Description:
AIMING APPARATUS

FIELD OF INVENTION

The present invention relates to aiming apparatus for mounting on a lighting apparatus. Particular embodiments relate to an aiming apparatus compensating for its placement on the lighting apparatus. BACKGROUND

Lighting apparatus are an essential part of the urban landscape to illuminate precise areas on vertical or horizontal surfaces. Accurate positioning of these lighting apparatus is especially important in highlighting particular events for a public, e.g. concerts, sport events, artistic events. However, typically, positioning of the lighting apparatus in an accurate manner is difficult because the aiming apparatus for mounting on the lighting apparatus introduces aiming errors.

Several solutions exist for assisting in the aiming of lighting apparatus. However they may present several disadvantages such as having to be incorporated in the lighting apparatus or introducing inaccuracies to be compensated for in a further step. Thus, aiming apparatus compensating for their placement on the lighting apparatus by applying an angular correction are not known at the time of the present invention, even though it would provide a more reliable and user-friendly way to aim the lighting apparatus. At the same time, such an aiming apparatus would be able to be adapted to different types of lighting apparatus used in events and used multiple times. Its placement would be compensated for by an adjustment means. Hence there is a need for aiming apparatus for mounting on a lighting apparatus with a compensating approach presenting these characteristics.

SUMMARY The object of embodiments of the invention is to provide an aiming apparatus which is more accurate to use and which allows quick and easy orientating of a lighting apparatus. More in particular, embodiments of the invention aim to provide an aiming apparatus which allows for an easy aiming of a lighting apparatus. According to a first aspect of the invention there is provided an aiming apparatus. The aiming apparatus for mounting on a lighting apparatus comprises: - a base configured for being placed at a side of the lighting apparatus, such that the aiming apparatus is withheld on the lighting apparatus;

- a support pivotally coupled to a first portion of the base;

- an adjustment means configured for adjusting the angular position of the support relative to said first portion of the base;

- an image -capturing device provided on the support;

- a communication module coupled to the image -capturing device and configured for

communicating data captured by the image -capturing device to a viewing device. Embodiments of the invention are based inter alia on the insight that a common oversight to aim a lighting apparatus with an aiming apparatus is done by first aiming the aiming apparatus in a direction parallel to an axis perpendicular to a light-emitting side of the lighting apparatus which can result in a mismatch of the aiming of the aiming apparatus with respect to the aiming of the lighting apparatus. By providing the support pivotally coupled to a first portion of the base and an adjustment means configured for adjusting the angular position of the support relative to said first portion of the base, the aiming angle difference can be compensated such that the viewed image data will correspond to the aiming of the lighting apparatus in its desired position and will thus be more precise.

Because the image -capturing device will provide image data of the direction towards which the aiming apparatus is aiming at to a viewing device using the communication module, a user can easily adjust the orientation of the lighting apparatus in function of the image data received by the viewing device, resulting in a fast and easy positioning of the lighting apparatus. The data viewed on the viewing device may be raw image data as captured by the image -capturing device and/or processed image data based on the raw image data to provide additional information, e.g. angular position, distance, visual enhancements. Displaying such processed image data on the viewing device further eases the aiming process. Preferably, the base is configured to allow for a stable placement of the aiming apparatus on the lighting apparatus to enhance the precision of the aiming apparatus. The aiming apparatus may be placed in different configurations with respect to the front, i.e. the illuminating face, of the lighting apparatus depending on the base design. The base may be placed on or over a top, bottom or lateral side of the lighting apparatus or may be placed on or over the front or back of the lighting apparatus.

According to an exemplary embodiment, the base is substantially U-shaped; and the substantially U-shaped base comprises besides the first portion, a second portion opposite of the first portion, and a third portion coupling the first and the second portion. The substantially U-shaped base results in a quick installation of the base at a side of the lighting apparatus. The U shape improves the introduction and the maintaining of the aiming apparatus at the side of the lighting apparatus by naturally preventing excessive lateral movements of the aiming apparatus; indeed, the first portion will be engaging with the front face of the lighting apparatus, and the second portion with the backside of the lighting apparatus. The U-shaped base may be installed at a top, bottom, or lateral side of the lighting apparatus, preferably centred with respect to the chosen side. In another exemplary embodiment, the U-shaped base may be installed over the back or front of the lighting apparatus. In the last case, the U-shaped base may block part of the light emitted from the lighting apparatus.

Centring the aiming apparatus by aligning the aiming apparatus position substantially orthogonally respective to an optical centre of the lighting apparatus improves the accuracy of the aiming apparatus. In another exemplary embodiment, the aiming apparatus may be placed at a distance from the chosen side centre of the lighting apparatus and may optionally comprise an additional adjustment means configured for further compensating the aiming apparatus position such that the angular position of the support relative to the base may be adjusted with respect to two different angular parameters.

According to a preferred embodiment, the adjustment means comprises:

- a moveable portion mounted between the support and the base and positionable in a plurality of different positions corresponding to different angular positions of the support relative to the base;

- a coupling means configured to maintain the support against the moveable portion in the different positions of the moveable portion.

In this manner, adjusting with the adjustment means is more accurate in defining an angular position. Indeed, a moveable means mounted between the support and the base will allow progressive adjustment of the angular position of the support relative to the base. In an exemplary embodiment, the moveable means may be pushing the support to increase the angular position. However for the moveable means to be effective, a coupling means is needed to maintain the moveable portion in contact with the support or the base. Moreover, the coupling means will allow the separation between the support and the base to increase or decrease such that, associated with the pivot coupling of the support and the base, it defines an angular modification.

According to an exemplary embodiment, at least one of the moveable portion or the coupling means comprises a curved portion in contact with the support or the base. In this way, the adjustment of the angular position of the support relative to the base is more continuous. Indeed, a curved portion of the moveable portion and/or the coupling means creates a better transition among the plurality of different positions by providing a smoother point of contact. Moreover, due to the continuity of the contact, steps between at least two of the plurality of different positions can be made infinitesimally small.

According to a preferred embodiment, the adjustment means further comprises an actuation means to actuate the moveable portion, such that a surface in contact with the curved portion is changed. In this manner, adjusting the adjustment means is made easier and more accessible to a user by the manipulation of an actuation means.

According to an exemplary embodiment, the actuation means comprises a wheel. In this way, the actuation means is more convenient to manipulate.

According to a preferred embodiment, the actuation means comprises a substantially angular scale for indicating the angular position of the support relative to the base. In this manner, adjusting the angular position can be done in a more reliable way. Moreover, adding an angular scale allows more precise positioning of the actuation means and can be associated more easily to the desired position of the lighting apparatus and the position of the aiming apparatus on the lighting apparatus. According to an exemplary embodiment, the moveable portion is fixed to the support or the base with a screw.

In this way, the moveable portion may have a continuous change in its position by the action of screwing or unscrewing, which in turn may lead to a continuous change of the angular position of the support relative to the base. It provides a more accurate angular compensation.

According to a preferred embodiment, the actuation means is arranged such that it can rotate the screw.

In this manner, the actuation means will have a direct action on the moveable portion. According to an exemplary embodiment, the aiming apparatus further comprises a holder means provided on the base, wherein the holder means is configured for holding the viewing device.

In this way, a viewing device can be held on the base of the aiming apparatus and increases the freedom of use of the aiming apparatus to a user. Note however, that the operator may use a mobile device as the viewing device without having the need of using the holder means; especially if the operator wears a wearable device, e.g. smartwatch, headgear and the likes. Also the viewing device could be integrated in the aiming apparatus. In yet another embodiment the viewing device (e.g. a computer or laptop) may be arranged at a distance of the aiming apparatus and may be connected wirelessly or in a wired manner to the communication device.

According to a preferred embodiment, the holder means comprises a bracket configured to receive the viewing device, such as a smartphone, a tablet, or any other display device. In this manner, the viewing device is held more securely, more particularly in the case of a smartphone or a tablet. In other embodiments the viewing device may be carried by the operator. The viewing device may be a wearable device, e.g. a smart watch, smart glasses.

According to an exemplary embodiment, the aiming apparatus further comprises a clamping means for clamping the base to the lighting apparatus.

In this way, the base can be withheld more securely on the side of the lighting apparatus, by applying additional pressure on the lighting apparatus. According to a preferred embodiment, the clamping means comprises a bolt having a first end functioning as a support feet pressed against the lighting apparatus and a second end having a head rotatable by a user, wherein the bolt cooperates with a bore in the second portion of the base.

In this manner, the clamping means is more user-friendly and provides an easy-to-operate and reliable means to withhold the aiming apparatus.

According to an exemplary embodiment, at least one of the first or the second portion of the base is pivotally coupled to the third portion. According to a particular embodiment, the third portion of the base may be extendable. In these ways, the base can be adapted and secured in a better way to various shapes and dimensions of the side of the lighting apparatus.

The skilled person will understand that the hereinabove described technical considerations and advantages for lighting apparatus embodiments also apply to the below described corresponding method embodiments, mutatis mutandis.

According to a preferred embodiment, there is provided a method for aiming a lighting apparatus with an aiming apparatus comprising an image -capturing device. The method comprises the following steps:

- adjusting the aiming apparatus to compensate for a difference between a first optical axis of the image-capturing device and a second axis perpendicular to a light-emitting side of the lighting apparatus;

- mounting the aiming apparatus at a side of the lighting apparatus, such that the aiming apparatus is withheld on the lighting apparatus;

- capturing image data and displaying data based on the captured image data on a viewing device;

- adjusting the orientation of the lighting apparatus based on the data displayed on the viewing device. To be mounted in a quick manner, an aiming apparatus is placed at a side of a lighting apparatus. Because of this mounting position, the first optical axis of the image-capturing device will not correspond with the second axis associated with the lighting apparatus. The second axis associated with the lighting apparatus may be an axis perpendicular to a light-emitting side of the lighting apparatus, or may be the optical axis of the lighting apparatus. Based on the separation between the first and the second axis, and on the distance to the area to be lit by the lighting apparatus and aimed at via the aiming apparatus, a compensation angle will be adjusted on the aiming apparatus to allow for a greater accuracy. Once adjusted, the aiming apparatus will be mounted. It is to be noted that the two first steps of this method can be switched in order, but adjusting the aiming apparatus may be done before the mounting for convenience-sake. The mounting may be preferably done substantially centred with respect to the chosen side for the aiming to be more rigorous. In another exemplary embodiment, the mounting may be done at a distance from the chosen side centre of the lighting apparatus and the adjusting of the aiming apparatus may optionally comprise adjusting the compensation angle according to two different angular parameters to further improve the aiming accuracy. Once mounted, image data will be captured and displayed on a viewing device for easily assessing the situation of the current aiming direction of the aiming apparatus. The data displayed may be raw image data as captured or processed image data to be more user-friendly. The lighting apparatus orientation will be adjusted such that the displayed image data correspond to the desired position of the lighting apparatus.

According to an exemplary embodiment, the method further comprises:

- removing the aiming apparatus from the lighting apparatus.

In this manner, the aiming apparatus may be reused in a further utilization. In other embodiments multiple viewing devices and/or aiming apparatus may be used at the same time. According to another aspect, there is provided an aiming apparatus. The aiming apparatus for mounting on a lighting apparatus comprises:

- a base configured for being placed at a side of the lighting apparatus, such that the aiming apparatus is withheld on the lighting apparatus;

- a support pivotally coupled to a first portion of the base;

- an adjustment means configured for adjusting the angular position of the support relative to said first portion of the base;

- an imaging-capturing device provided on the support;

- a communication module coupled to the image -capturing device and configured for

communicating data captured by the image -capturing device to a signalling device, e.g. a mobile device or a wearable device or a lighting device.

In an exemplary embodiment, the signalling device, such as the mobile device or the wearable device or the lighting device, may comprise a display and may be configured for being used as the image viewing device. In another exemplary embodiment, additionally to or instead of the display, the signalling device, such as the mobile device or the wearable device, may comprise a communication module configured for outputting an output signal, and in particular for emitting an audio signal, and/or a haptic signal, and/or a vibration signal and/or a light signal based on data captured by the image-capturing device. In an exemplary embodiment, the signalling device may comprise a plurality of LEDs, e.g. integrated in the aiming apparatus or in the lighting apparatus. The light signal output by the plurality of LEDs may then be changed (e.g. a colour change) in function of the captured image data. The captured data may be processed to indicate an error in orientation of the lighting apparatus and the output signal may optionally indicate an orientation correction to be achieved in order for the lighting apparatus to reach an appropriate orientation. The skilled person will understand that the hereinabove described technical considerations and advantages for aiming apparatus embodiments in which data is communicated to the image - viewing device also apply for aiming apparatus embodiments in which data is communicated to the mobile or wearable device, mutatis mutandis. According to yet another aspect there is provided a method for aiming a lighting apparatus with an aiming apparatus comprising an image -capturing device, preferably an aiming apparatus according to any one of the previous embodiments, the method comprising the following steps:

- adjusting the aiming apparatus to compensate for a difference between a first optical axis of the image-capturing device and a second axis perpendicular to a light-emitting side of the lighting apparatus;

- mounting the aiming apparatus on the lighting apparatus, such that the aiming apparatus is withheld on the lighting apparatus;

- capturing image data and communicating the captured image data to a signalling device, e.g. a mobile device or a wearable device or a lighting device;

- outputting data based on the captured image data via the signalling device, e.g. emitting an audio signal, and/or a haptic signal, and/or a vibration signal, and/or a light signal based on the captured image data;

- adjusting the orientation of the lighting apparatus based on the data output by the signalling device.

Figure 1 shows a side view of an exemplary embodiment of an aiming apparatus according to the present invention. The aiming apparatus 100 comprises a base 110, a support 120, an adjustment means 130, an image-capturing device 140, and a communication module 150. The base 110 is substantially U-shaped and is configured for being placed at a side 210 of the lighting apparatus 200, e.g. a top side 210 as illustrated in the exemplary embodiment of Figure 4. In other exemplary embodiments, the base 110 may be placed at a bottom side or a lateral side of the lighting apparatus 200. In still another exemplary embodiment, the base 110 may differ in shape from a U- shaped base and may be placed at the side 210 of the lighting apparatus 200 via an attachment means. The attachment means may be specific to the lighting apparatus 200 with a design adapted to fit the side 210 of the lighting apparatus 200. Additionally or alternatively, the attachment means may comprise elements such as locking pins, suction cups, or retaining clips, such that the base is held at a predetermined angular position with respect to an optical axis of the lighting apparatus 200. The skilled person will understand that different embodiments of the base are possible to allow its secure positioning on the side 210 of the lighting apparatus 200 to achieve the desired effect.

In the exemplary embodiment of Figure 1, the base 110 is substantially U-shaped and comprises a first portion 111 , a second portion 112 opposite of the first portion 111, and a third portion 113 coupling the first portion 111 and the second portion 112. The first portion 111 and the third portion 113 are pivotally coupled, and the second 112 and the third portion 113 are pivotally coupled. In another embodiment as illustrated in Figure 2, the second 112 and the third portion 113 are not coupled by a pivot and the third portion 113 may be configured to be telescopic.

The skilled person will understand that various designs of the first 111, the second 112, and the third portion 113 can be implemented to better adapt the base 110 being placed and withheld at a side 210 of the desired lighting apparatus 200. For example, Figure 1 illustrates an embodiment where the coupling between the first 111 and the third portion 113 is in an upper part of the first portion 111, and Figure 2 illustrates an embodiment where the coupling between the first 111 and the third portion 113 is in a central part of the first portion 111, as will be described in detail below.

The first portion 111 comprises a first face 111a placed against the light-emitting side of the lighting apparatus 200, and a second face 11 lb opposite of the first face 111a; side faces extend between the first 111a and the second face 11 lb of the first portion 111. The support 120 is pivotally coupled and mounted such that it faces the second face 11 lb of the first portion 111. The support 120 comprises a first face 120a facing the second face 11 lb of the first portion 111, and a second face 120b of the support 120 opposite to the first face 120a of the support 120. The image- capturing device 140 is provided on the second face 120b of the support 120. The communication module 150 is coupled to the image -capturing device 140 and is configured for communicating image data captured by the image -capturing device 140 to a viewing device. The communication module 150 may be part of the image-capturing device 140 or provided separately.

The adjustment means 130 is configured for adjusting the angular position of the support

120 relative to the first portion 111 of the base 110. The adjustment means 130 comprises a moveable portion 131, and a coupling means 132. The moveable portion 131 is mounted between the support 120 and the base 110 and is positionable in a plurality of different positions corresponding to different angular positions of the support 120 relative to the base 110. In the exemplary embodiment of Figure 1, the moveable portion 131 comprises a curved portion 133 in contact with the first face 120a of the support 120. In other embodiments, the contact between the moveable portion 131 and the support 120 or the base 110 may be a point contact, a linear contact, or a planar contact. In still another embodiment, the adjustment means 130 may be a double-ended nut cooperating at one end with a first bolt fixed to the support 120, and at another end with a second bolt pivotally coupled, e.g. with a ball-head and a spring, to the first portion 111 such that rotating the nut may change the angular position of the support 120 relative to the first portion 111.

The coupling means 132 is configured to maintain the support 120 against the moveable portion 131 in the different positions of the moveable portion 131. The curved portion 133 may be spherical, cylindrical, or elliptical. For instance, Figure 1 illustrates an embodiment where the curved portion 133 is a spherical portion.

The adjustment means 130 further comprises an actuation means, e.g. a lever, a wheel, to actuate the moveable portion 131, such that the surface in contact with the curved portion 133 is changed. Figure 1 illustrates an embodiment where the actuation means comprises a wheel 135. The wheel 135 may be a disk section with a first circular end and a second circular end. The curved portion 133 may be provided at the centre of the second end of the wheel 135. The first end of the wheel 135 may be fixed to the base 110 with a screw 137, wherein the screw may cooperate with a bore in the first portion 111. The wheel 135 may be rotated by a user.

The coupling means 132 may couple the support 120 to the base 110, such that the moveable portion 131 mounted in-between has its curved portion 133 in contact with the support 120. In the exemplary embodiment of Figure 1, the support 120 is pivotally coupled to a bottom part of the first portion 111 of the base, and is coupled to an upper part of the first portion 111 through a ball-head and a spring to allow a continuous change of the angular position of the support 120 relative to the first portion 111 of the base 110. Rotating the wheel 135 clockwise or anti-clockwise may move the moveable portion 131 away from the base 110; the curved portion 133 of the moveable portion 131 may change its surface in contact with the support 120 and move the support 120 away from the base 110, adjusting the angular position of the support 120 relative to the first portion 111 of the base 110. The wheel 135 may comprise a substantially angular scale 136 for indicating the angular position of the support 120 relative to the base 110, based for instance on the screw 137 used and on the dimensions and position of the curved portion 133.

In the exemplary embodiment of Figure 1, the first portion 111 and the third portion 113 are pivotally coupled on both sides of the upper part of the first portion 111 such that the third portion 113 may rotate away from the first face 111 a of the first portion 111. Other designs of pivot coupling may be used by the skilled person, e.g. swivel, hinge, and may comprise one or more coupling points. The third portion 113 may extend away from the first portion 111 substantially perpendicularly. The second portion 112 may extend substantially perpendicularly away from the third portion 113, opposite of the first portion 111. The second portion 112 and the third portion 113 may be pivotally coupled. For example, Figure 1 illustrates an embodiment where the second 112 and the third portion 113 are coupled at each other end. Figure 1 shows the first 111, the second 112, and the third portion 113 that may be pivoted to engage with the side 210 of the lighting apparatus 200 such that the aiming apparatus 100 can be withheld on the lighting apparatus 200.

The aiming apparatus, according to the embodiment of Figure 1, further comprises a holder means 160 provided on the second portion 112 of the base 100. The holder means 160 is configured for holding the viewing device. The holder means 160 may be a bracket configured to receive the viewing device, e.g. a smartphone or a tablet. The communication module 150 coupled to the image-capturing device 140 is configured for communicating image data captured by the image-capturing device 140 to the viewing device wirelessly or in a wired manner. Alternatively, the viewing device may be a computer device. The image data may be processed to increase the aiming accuracy and to provide a more user-friendly interface.

The aiming apparatus 100 comprises a base 110, a support 120, an adjustment means 130, an image-capturing device 140, and a communication module 150. The base 110 comprises a first portion 111 , a second portion 112, and a third portion 113. The first portion 111 comprises a first face 111a and a second face 11 lb opposite of the first face; side faces extend between the first face 111a and the second face 11 lb of the first portion 111. The first face 11 la of the first portion 111 is placed against the light-emitting side of the lighting apparatus 200. The third portion 113 may be pivotally coupled on both side faces of a central part of the first portion 111 via two side parts, wherein the two side parts of the third portion 113 may extend along the side faces of the first potion 111. The two side parts of the third portion 113 may be connected to a second part substantially perpendicular to the two side parts. The third portion 113 may extend away from the first portion 111. The second portion 112 may be connected to an end of the second part of the third portion 113, and may extend substantially perpendicularly away from it, opposite to the first portion 111.

The third portion 113 of the base 110 may be extendable by a telescopic -like mechanism. The telescopic -like mechanism may comprise a first part 113a and a second part 113b sliding within the first part 113a such that the distance between the first portion 111 and the second portion 112 of the base may be varied. A blocking means 113c may allow the position of the first part 113a with respect to the second part 113b of the third portion 113 to be fixed. Thus the base 110 may be adapted to lighting apparatus 200 of varied dimensions.

The aiming apparatus 100 may comprise a clamping means 170 for clamping the base 110 to the lighting apparatus 200, provided to the second portion of the base 100 in the embodiment of Figure 2. The clamping means 170 may comprise a bolt having a first end functioning as a support feet 171 pressed again the lighting apparatus 200 and a second end having a head 172 rotatable by a user, wherein the bolt cooperates with a bore in the second portion 112 of the base 110.

The support 120 is pivotally coupled to the first portion 111 of the base 110. The support 120 comprises a first face 120a facing the second face 111b of the first portion 111, and a second face 120b opposite to the first face 120a of the support 120. The image-capturing device 140 and the communication module 150 may be provided on the second face 120b of the support 120. Figure 2 shows a spherical portion provided on a bottom part of the first face 120a of the support 120. It corresponds to a recess in the second face 11 lb of the first portion 111 of the base 110 such that there may be a pivotal movement allowed by the contact surface between the spherical portion and the recess.

The adjustment means 130 comprises a moveable portion 131 and a coupling means 132. In the exemplary embodiment of Figure 2, the coupling means 132 is coupled to a central part of the second face of the first portion 111 through a ball-head and a spring. The moveable portion 131 may comprise a curved portion 133, e.g. a spherical portion, in contact with the first portion 111. The adjustment means 130 may comprise an actuation means, e.g. a wheel 135, a lever. Figure 2 shows the wheel 135, wherein the wheel 135 is a disk section with a first circular end and a second circular end. The wheel may 135 be fixed to the support 120 with a screw 137 provided at the centre of the second end of the wheel 135 and cooperating with a bore in the support 120. The curved portion 133 is provided at the centre of the first end of the wheel 135.

The wheel 135 is rotatable by a user. Rotating the wheel 135 anti-clockwise or clockwise may move the moveable portion 131 away from the first face 120a of the support 120 and may increase the angular position of the support relative to the first potion 111 of the base 120. The wheel 135 may comprise a substantially angular scale 136 for indicating the angular position of the support 120 relative to the base 110. A calibration screw 137 may be provided to the base 100 for adjusting the angular position of the support 120 relative to the first portion 111 of the base 110 at a referenced angle.

Figure 3 shows a side view of a further exemplary embodiment of an aiming apparatus according to the present invention. The aiming apparatus 100 comprises a base 110, a support 120, an adjustment means 130, an image-capturing device 140, and a communication module 150 (not shown). The base 110 comprises a first portion 111, a second portion 112, and a third portion 113.

The first portion 111 of the base 110 may be substantially U-shaped, as illustrated in the embodiment of Figure 3. The support 120 may be pivotally coupled to the upper part of both side parts of the U of the first portion 111, such that the support 120 may rotate in-between the side parts of the U of the first portion 111. The image-capturing device 140 is provided on the support 120.

The adjustment means 130 is provided between the support 120 and the base 110. The adjustment means 130 comprises a moveable portion 131 and a coupling means 132. Figure 3 illustrates an embodiment where the moveable portion 130 is provided on a bottom part of the U of the first portion 111, and comprises a curved portion 133 in contact with a bottom part of the support 120. The adjustment means 130 comprises an actuation means, a wheel 135 in Figure 3. A screw 137 may be provided at the centre of one end of the wheel 135 and may cooperate with a bore in the bottom part of the U of the first portion 111. Rotating the wheel 135 clockwise or anti- clockwise may move the support 120 away from the bottom part of the U of the first portion 111 and may increase the angular position of the support 120 relative to the first portion 111. The wheel 135 may comprise an angular scale 136 for indicating the angular position of the support 120 relative to the base 110.

The first portion 111 may be pivotally coupled to the third portion 113 on the upper part of both side faces of the first portion 111. The second portion 112 may comprise a first and a second part. The first part may be pivotally coupled to an end of the third portion 113. The second part may be connected to the first part and may extend substantially perpendicularly away from the first part, opposite to the first face 11 la of the first portion 111.

A clamping means 170 for clamping the base 110 to the lighting apparatus 200 may be comprised in the aiming apparatus 100; it is provided on the second part of the second portion 112 in the embodiment of Figure 3. The clamping means 170 may comprise a bolt having a first end functioning as a support feet pressed against a flexible plate of the second portion 112, such that the flexible plate may be pressed against the lighting apparatus 200, and a second end having a head 172 rotatable by a user, wherein the bolt cooperates with a bore in the second portion 112 of the base 110. Figure 4 illustrates a side view of a further embodiment of the aiming apparatus according to the present invention. The aiming apparatus 100 comprises a U-shaped base 110, an image -capturing device 140, and a communication module 150. The communication module 150 is coupled to the image-capturing device 140 wirelessly or in a wired manner, and is configured for communicating image data captured by the image -capturing device 140 to a viewing device (not shown). The viewing device is viewed by a user and may be a computer device.

The base 110 allows the aiming apparatus to be placed at a side 210 of a lighting apparatus 200 and to be withheld on the lighting apparatus 200. The U-shaped base 110 may be installed at a top, bottom, or lateral side of the lighting apparatus 200, preferably centred with respect to the chosen side, centred at the top side 210 of the lighting apparatus 200 in the exemplary embodiment of Figure 4. Centring the aiming apparatus 100 by aligning the aiming apparatus 100 position substantially orthogonally respective to an optical centre of the lighting apparatus 200 improves the accuracy of the aiming apparatus 100. In another exemplary embodiment, the aiming apparatus 100 may be placed at a distance from the chosen side centre of the lighting apparatus 200 and may comprise an additional adjustment means configured for further compensating the aiming apparatus 100 position such that the angular position of the support 120 relative to the base 110 may be adjusted with respect to two different angular parameters.

The lighting apparatus 200 emits light in a direction parallel to the optical axis of the lighting apparatus 200. The light emitted is projected on a surface 300, e.g. sport field. The image - capturing device 140 captures image data in a direction parallel to a first optical axis 303 of the image-capturing device 140.

The lighting apparatus 200 may have to light a specific area of the surface 300. An aiming point 302 associated to the area to be lit may be marked visually on the surface 300. The aiming point 302 may be desired to be corresponding to a second position 304a of a second axis 304 associated with the lighting apparatus 200 when projected on the surface 300. The aiming point 302 may be corresponding to a desired orientation of the lighting apparatus 200. The second axis 304 associated with the lighting apparatus 200 may be an axis passing trough the centre of a light- emitting side of the lighting apparatus 200 and perpendicular to said light-emitting side. The second axis 304 may instead be the optical axis of the lighting apparatus 200.

The aiming apparatus 100 role is to aim the second projected position 304a of the second axis 304 at the aiming point 302 while taking into account the angular correction needed to compensate for the placing of the aiming apparatus 100 at the side 210 of the lighting apparatus. The aiming of the aiming apparatus 100 is deemed fulfilled if a first projected position 303a of the first optical axis 303 of the image-capturing device 140 is within a predetermined distance of the aiming point 302 when corresponding to the second projected position 304a of the second axis 304. Figure 5 illustrates schematically an exemplary embodiment of a method for aiming a lighting apparatus with an aiming apparatus according to the present invention. The method 50 comprises adjusting the aiming apparatus 51, mounting the aiming apparatus 52 on the lighting apparatus, capturing image data 53, displaying image data 54, adjusting the orientation of the lighting apparatus 55, and optionally removing the aiming apparatus 56.

The aiming apparatus 100 comprises an image-capturing device 140. The position of the lighting apparatus 200 may have to be adjusted to be in a desired position such that a specific area of a surface 300 may be lit by the lighting apparatus 200. The specific area to be aimed at by the aiming apparatus 100 may be marked visually such that an axis 304 perpendicular to a light- emitting side of the lighting apparatus 200 and passing through the centre of said light-emitting side, when projected on the lit surface 300, corresponds to the centre of the specific area when in the desired position, i.e. an aiming point 302.

The aiming apparatus 100 may be used for aiming the lighting apparatus 200 to this specific area. The aiming apparatus 100 may be mounted at a side 210 of the lighting apparatus 200. The aiming apparatus 100 may be mounted at a top side, a bottom side, or a lateral side. The image-capturing device 140 will capture image data, see step 53 in figure 5. However the optical axis 303 of the image-capturing device 140 does not correspond to the axis 304 associated with the lighting apparatus 200 due to its mounting position. In order to compensate for the difference between the two axes 303, 304, a prior adjusting of the aiming apparatus (step 51 in figure 5) may be done.

The distance between the two optical axis 303, 304 from their respective origin point, the distance from the aiming point 302 to the image-capturing device 140, and the distance from the aiming point 302 to the lighting apparatus 200 define an angle between the two axes 303, 304, such that the two axes 303, 304 meet at the aiming point 302. The defined angle is adjusted for on the aiming apparatus, see step 51 in figure 5.

The aiming apparatus is mounted (see step 52 in figure 5) on the lighting apparatus 200. A U-shaped base 110 comprised in the aiming apparatus 100 allows the aiming apparatus 100 to be withheld on the side 210 of the lighting apparatus 200. It is to be noted that the steps of adjusting the aiming apparatus 51 , and mounting the aiming apparatus 52 may be switched in order.

The image-capturing device 140 provided to the aiming apparatus 100 captures image data facing the aiming apparatus 100. However, given the angular difference between the optical axis 303 of the aiming apparatus and the axis 304 associated with the lighting apparatus, the image data may only partially overlap with the area to be aimed at with the lighting apparatus 200 when the lighting apparatus 200 is not in the desired position.

The image data are transferred to a viewing device to be displayed (see step 54 in figure 5) through the use of a communication module 150 coupled to the image-capturing device 140. A user views the displayed image data, see step 54. The viewing device may be a tablet, a smartphone, or a screen connected via the communication module 150 to the image-capturing device 140. The viewing device may be mounted to the base 110 of the aiming apparatus 100, e.g. with a bracket, such that the aiming apparatus 100 is easier to operate. The data displayed may be the raw image data as captured or processed image data to include additional information, e.g. angular position, distance, altered visualization, to the user.

Depending on the image displayed the orientation of the lighting apparatus 200 is adjusted, see step 55. If the adjusting of the aiming apparatus (step 51 in figure 5) is done within accepted tolerances, the adjusting of the lighting apparatus (step 55 in figure 5) may be achieved by adjusting the lighting apparatus orientation such that the displayed image aims at the aiming point 302.

For example, the data displayed on the viewing device may be a live feed view of the image data captured by the image -capturing device 140 connected via the communication module 150 and the aiming point 302 may be a visual mark on the surface to aim at. Alternatively, the data displayed may be processed by a processor comprised in the viewing device, or processed remotely in a remote device connected to the viewing device.

According to exemplary embodiments, a predetermined angular position of the lighting apparatus 200 to reach may be stored in the viewing device or the remote device and retrieved based on an identification of the lighting apparatus 200. The aiming point 302 may also be retrieved from a GPS tag placed on the surface to aim at. The processor of the viewing device or remote device may process the captured image data, and optionally process additional information captured by additional sensing means, determine the current orientation of the lighting apparatus 200, and compare the current determined orientation of the lighting apparatus 200 to the predetermined angular position, to reach the aiming point 302. From the difference between the current determined orientation of the lighting apparatus 200 and the predetermined angular position, it may be derived whether the lighting apparatus 200 is correctly positioned, and optionally a correction may be derived.

For example, the correction may be displayed on the viewing device via arrows indicating through different visual effects, e.g. blinking, colouring, transparency, towards which direction the lighting apparatus 200 has to be oriented. In another embodiment, in addition to or instead of the visual information from the viewing device, the orientation correction of the lighting apparatus 200 may be communicated to the operator via another output signal, such as an audio signal, a haptic signal, and/or a vibrating signal and/or a light signal. Also, a signalling means with physical indication means such as arrows may be used. Optionally, such a signalling means may be integrated in the aiming apparatus or in the lighting apparatus. Additional data to further process the correction may be stored in the remote device or the viewing device associated with the lighting apparatus 200, e.g. maintenance history, functioning history, geographical position, optics parameters. The viewing device may show a live feed view of the image data captured by the image-capturing device 140 together with the correction needed for the incorrectly placed lighting apparatus 200. Alternatively or additionally, the viewing device may indicate visually whether the lighting apparatus has reached the aiming point 302.

The viewing device may display information to the field operator based on the position information data for each lighting apparatus 200 of a plurality of lighting apparatus installed to illuminate a particular location, e.g. a stadium or arena. The viewing device may show an overview

representing the position information data for each lighting apparatus 100 of the plurality of lighting apparatus as a list or a table. The viewing device may, instead or additionally, exhibit a geographical map indicating at least the lighting apparatus 200 for which the position information data indicates that the angular positioning is not correct. The geographical position of the plurality of lighting apparatus 200 may have been sent from the remote device based on stored data or data measured from a GPS receiver comprised in the corresponding lighting apparatus 200. The adjusting of the lighting apparatus (step 55 in figure 5) is deemed fulfilled if a first projected position 303a of the optical axis 303 of the image-capturing device and a second projected position 304a of the axis associated with the lighting apparatus on the surface 300 are below a

predetermined distance based on lighting intensity tolerances.

The aiming apparatus 100 may be removed 56 before reuse for aiming another lighting apparatus 200.

In Figures 6A-6C, the aiming apparatus 620 comprises a base 630a, 630b, 630c, a support 640a, 640b, 640c, an adjustment means (not shown), an image-capturing device 650, and a communication module (not shown). The lighting apparatus 610 comprises a front surface 611 which may be emitting light, a back surface 612 opposite the front surface, and a lateral surface 613 extending between the front surface 611 and the back surface 612.

As illustrated in Figures 6A-6B, the base 630a, 630b may be substantially U-shaped and may comprise a first portion 631a, 631b, a second portion 632a, 632b, and a third portion 633a, 633b. In the embodiment of Figure 6C, the base 630c may differ in shape from a U-shaped base and may be placed at the side of the lighting apparatus 610 via an attachment means. The attachment means may be specific to the lighting apparatus 610 with a design adapted to fit the side of the lighting apparatus 610. Additionally or alternatively, the attachment means may comprise elements such as locking pins, suction cups, or retaining clips, suction cup 631c in the exemplary embodiment of Figure 6C, such that the base 630c is held at a predetermined angular position with respect to an optical axis OA of the lighting apparatus 610. The skilled person will understand that different embodiments of the base 630a, 630b, 630c are possible to allow its secure positioning on the side of the lighting apparatus 610 to achieve the desired effect.

The support 640a, 640b, 640c may be pivotally coupled a portion of the base 630a, 630b, 630c. The image-capturing device 650 is provided on the support 640a, 640b, 640c. In the embodiment of Figure 6A, the support 640a is provided to the second portion 632a of the base such that it is located on top of the lateral surface 613 of the lighting apparatus, substantially aligned relative to the optical axis OA of the lighting apparatus 610. In the embodiment of Figure 6B, the support 640b is provided to the second portion 632b of the base such that it is located on the upper part of the front surface 611 of the lighting apparatus, off-center relative to the optical axis OA of the lighting apparatus 610. In the embodiment of Figure 6C, the support 640c is provided to the base 630c such that it is located on the side part of the front surface 611 of the lighting apparatus, substantially aligned relative to the optical axis OA of the lighting apparatus 610.

Depending on the design of the base 630a, 630b, 630c, the aiming apparatus 620 may be placed on different sides of the lighting apparatus 610. In the exemplary embodiment of Figure 6 A, the base 630a is substantially U-shaped and the first and third portion 631a, 633a may be placed over the front and back surfaces 611, 612 of the lighting apparatus such that the second portion 632a of the base is across the top part of the lateral surface 613 of the lighting apparatus. In the exemplary embodiment of Figure 6B, the base 630b is substantially U-shaped and the first and third portion 631b, 633b may be placed over the top part and the bottom part of the lateral surface 613 of the lighting apparatus such that the second portion 632b of the base is across the front surface 611 of the lighting apparatus. In the exemplary embodiment of Figure 6C, the base 630c is provided directly to the front surface 611 of the lighting apparatus via the suction cup 631c.

A viewing device (not shown) communicates with a communication module (not shown) coupled to the image -capturing device 650 and can be held on the base 630a, 630b, 630c of the aiming apparatus, thereby increasing the freedom of use of the aiming apparatus 620 to an operator. Note however, that the operator may use a mobile device as the viewing device without having the need of using a holder means; especially if the operator wears a wearable device, e.g. smartwatch, headgear and the likes. In another embodiment, in addition to or instead of the visual information from the viewing device, orientation information of the lighting apparatus 610 may be communicated to the operator via another output signal, such as an audio signal, a haptic signal, and/or a vibrating signal and/or a light signal.
