When working out the solution according to the invention we aimed to create an equipment, which allows the production of a special tunnel-like lighting effect from the direction of one side or both sides, which equipment could function also as a simple mirror when turned off.

When creating the solution according to the invention we realized as an inventive step, that if mirror and semi-transparent mirror or mirrors are placed in an external frame, which is capable of holding and fixing them firmly, and if light sources, in the given case an internal frame containing LEDs is placed between the mirrors, then the set aim can be achieved.

The invention is a lighting equipment with three dimensional effect, which equipment has lighting units mounted on a frame. It is characterized by that the equipment has an outside frame, a front panel made of semi-transparent mirror placed in the external fame, and has a rear panel made of semi-transparent mirror or mirror, which are placed in grooves formed in the external frame, and there is an internal frame between the front panel and the rear panel, to which the lighting units, of the equipment, made of LEDs are fixed.

In a further prefered application of the method according to the invention the front panel is aligned at a given angle, and the rear panel is aligned at another given angle (β) relative to the internal surface of the external fame, and the front panel and the rear panel are parallel to each other, i.e. they are aligned with a = 90° and β = 90° relative to the external frame.

In a further prefered application of the method according to the invention the front panel and the rear panel have an angle a = 90°, β= 85-87° relative to the internal surface of the external frame.

In a further prefered application of the method according to the invention the material of the external frame is wood, or metal, or plastic, and the external frame is fitted together from a number of partial units, and are connected or joined with known method at their places, in the given case by means of screwing or adhering.

The Fig. 1 shows the front view of the equipment 1 according to the invention.

The Fig. 2 shows section A- A of the equipment 1 introduced in Fig. 1.

The Fig. 3 shows the view of the internal frame 5 of the equipment 1 according to the invention.

The Fig. 4 shows the section C-C of the internal frame introduced in Fig. 3.

The Fig. 5 show the enlarged image of detail B of the equipment indicated in Fig. 2.

The Fig. 1 shows the front view of the equipment 1 according to the invention. The items shown in the figure are the external fame 2 of the equipment 1, the front panel 3 made of semi-transparent mirror placed in the external frame 2. Also, there is a dashed line included in the figure to show the internal frame 5 with LEDs 6 placed inside the equipment 1, as well as the electrical connection opening 10 formed in the external frame 2.

The Fig. 2 shows section A- A of the equipment 1 introduced in the Fig. 1. The items shown in the figure are the external fame 2 of the equipment 1, and the front panel 3 made of semi-transparent mirror placed in the groove 8 of the external frame 2, as well as the rear panel 4 made of semi-transparent mirror in the given case or mirror place in its groove 9. The figure also shows the internal fame 5 placed between the front panel 3 and the rear panel 4 inside the equipment 1, which serves for supporting the LEDs 6. The LEDs 6 can be seen on the internal surface of the internal frame 5 fixed to the carrier strip 7.

The Fig. 3 shows the view of the internal frame 5 of the equipment 1 according to the invention. In case of the embodiment shown in the figure the internal frame 5 has a circular shape, on the internal surface of which internal frame 5 the LEDs 6 are placed on a carrier strip 7. In the given case, the carrier strip 7 ensures the electrical supply to the LEDs 6 with the help of leads routed within it. The Fig. 4 shows the section C-C of the internal frame introduced in the Fig. 3. The figure shows the internal frame 5 and the carrier strip 7 with mounted LEDs 6 on one of the surface of internal frame 5.

The Fig. 5 show the enlarged image of detail B of the equipment indicated in the Fig. 2. The items depicted in the figure include external frame 2 of the equipment, the front panel 3 of the external frame 2 placed in the groove 8, and the rear panel 4 placed in groove 9. Also, the figure shows the internal frame 5 placed between the front panel 3 and the rear panel 4 inside the equipment 1. The LEDs 6 fixed on the carrier strip 7 can be seen on the internal surface of the internal frame 5.

It can be seen in the Fig. 5 that the external frame 2 has a thickness V, and the grooves 8, 9 formed in the external frame 2 have a depth dimension M, and the grooves 8, 9 are located at a distance K from the edge of the external frame 2. The internal surface of front panel 3 and the rear panel 4 in the external frame 2 are located at a distance T from each other, whereas the spatial effect provided by the equipment 1 can be varied by changing the distance T. It can also be seen in the figure, that the front panel 3 placed in the 8,9 grooves has an angle a, and the rear panel 4 has an angle β relative to the internal surface of the external fame 2. The spatial affect provided by the equipment 1 can be influenced by changing angle a of front panel 3 and angle β of rear panel 4.

In case of a possible embodiment of the equipment according to the invention a = 90° and β = 90, therefore, the front panel 3 and the rear panel 4 are parallel to each other. In this case the visual effect produced by the equipment is an image similar to a straight tunnel, in which the LEDs 6 appear as concentric circles.

In case of another possible embodiment of the equipment according to the invention α>β, in the given case a = 90°, and β < 90°, preferably β= 85-87°, therefore, the front panel 3 and the rear panel 4 are inclined relative to each other by several degrees. In this case the visual effect produced by the equipment is an image of a slightly curved tunnel, in which the LEDs 6 appear as circles inclined relative to one another. In case of a possible actual embodiment of the solution according to the invention, a separate control unit is used to control the operation of LEDs 6, which works in a preprogrammed mode, or can be operated with a remote controller. This arrangement enhances the experiments in terms of colours and other visual effects.

An important feature is that there are two frames embedded into one other. There is an external frame 2, which ensures the fastening and mechanical stability of the elements of the equipment 1, and an internal frame 5 in which the LEDs 6 are placed. The material of the external frame 2 can be wood, metal or plastic. The shapes of the external frame 2 and the internal frame 5 are not identical, there is a certain distance, a gap between them. In addition to the physical fixing of the LEDs 6 it has a function of cooling the LEDs 6 or other lighting bodies. For this reason the material of the internal frame 5 is preferably metal, steel, copper, etc., but it could be made also from plastic. This improved cooling ensures a longer life span for LED 6.

In case of a preferred embodiment of the solution, the front panel 3 and the rear panel 4 acting as two mirrors, at least one of them is a semi-transparent mirror, aligned opposite to each other in parallel or close to parallel, and there are a row of light made from LEDs 6 between them. The row of light made of LEDs 6 are located at equal distances from the mirrors between them. The inclination of the mirrors relative to the parallel is a couple of degrees, preferably 3-5°. This improves the spatial experience, and it modifies the image in a way that the observer does not see a straight tunnel with parallel wall, but a slightly curving tunnel depending on the inclination angle of the mirrors.

According to a preferred embodiment of the equipment 1 according to the invention the shape, form of external frame 2 and the internal frame 5 can be arbitrary. It can be angular, arched or arbitrary shaped by the combination of these shapes according to the need. The external frame 2 and the internal fame 5 can have different shapes even, for instance, an arched internal frame 5 can be placed in a rectangular external frame 2. The internal arched design results in a tunnel-like light effect. It is advantageous to have a certain distance between the external frame 2 and the internal frame 5 in order to improve the efficiency of cooling. In the given case, the lighting bodies, the LEDs 6 are placed on a "LED strip", which ensures the voltage supply and the mechanical fixing. This is a commercially available product.

The external frame 2 and the internal frame 5 could have different shapes or designs, but always two frame are used, an external frame 2, and an internal frame 5 inserted in it so that the cooling of the lighting bodies could be ensured.

In case of the equipment according to the invention the depth M of the external frame 2, and in turn, the distance L between the front panel 3 and the rear panel 4 influences the depth of the spatial tunnel seen, experienced. For instance, when the external frame 2 is 8 cm wide, and the mirror distance is L=6 cm, the spatial experience is a tunnel about 1- 1.5 m deep, and in case of mirror distance L= 25-30 cm, the spatial experience is a tunnel 5-6 m deep.

The equipment according to the invention may be designed with a full mirror at one side, meaning that the rear panel 4 is a full mirror, and the other, the front panel 3 at the side of the observer is a semi-transparent mirror, the so called observation mirror. In this case the equipment can be looked at from one side, and the spatial experience is detected only from one of the sides. This design can be used if the equipment is mounted on a wall or placed in front of a closed surface.

In case of another possible design, a semi-transparent mirror is inserted at both sides, meaning that the front panel 3 and the rear panel 4 is a semi-transparent mirror. If the equipment is set up alone within a space, then the spatial experience is observable from both sides. For the observer it makes a tunnel-like image, the illusion of an infinite tunnel when viewed from any of the sides.

Various objects can be placed within the equipment 1 according to the invention at the centre of the internal frame 5 between the front panel 3 and the rear panel 4. These objects could have reflecting or light emitting properties themselves, e.g. bright sphere or other spatial shape, or further row of lights, row of LEDs, which provide further tunnel-like experience. The other objects could include ornamental pieces, jewellery, pictures, logos or emblems. For advertising purposes the logo of a given product or make appears with a very interesting spatial effect, the equipment ensures a special spatial experiment for it. When the internal lighting of the equipment 1 is turned off, then the equipment 1 appears to be a simple mirror, and it could be used as such.

Further preferred options for use are as follows:

As a mirror, and in turned on state, as an object providing spatial effects, functioning as a general interior object or office decoration or ornamental item, or as a subdued lighting.

In case of this use, it can be mounted on walls or office furniture or any other furniture item.

It can be installed in desks, or can be placed in suspended ceilings or in flooring. It is the actual installation which determine whether the semi-transparent mirror is used only at one side or both sides.

Application at outdoor locations for advertising purposes.

It can be used as advertising board, trade sign, mounted on external wall, aligned perpendicularly to the wall, in shop windows or as part of shop windows, as well as in openings (door, window, space separators).

A small consumption with high luminous power can be ensured with the use of state of art light sources, in the give case LEDs with a single or multiple colours.

In terms of electrical safety the equipment does not require separate measures to ensure protection of life, because the included light sources, the LEDs operate at low voltages, in the given case at 12 V. In the given case, if the consumption of LED is 5 Watt, then the current input from the mains is 28 - 30 mA. The connection to the generally available electrical mains having a voltage of 220-230 V takes place in every case with an adapter, which is safe in terms of life protection. If the size of the assembly is large, having a diameter of 1-1.5 m, then the consumption of the LEDs could reach 100 W or several 100 W. For this purpose it is necessary to ensure the appropriate power supply, as well as the safe leading of the power voltage. In case of a large assembly, having a higher luminous power, it could operate as self contained lighting equipment for a given room or surface, without using additional illumination.

The advantage of the solution according to the invention is that with the help of lighting means, row of lights consisting of LEDs a special tunnel-like spatial image is produced, and at the same time, the equipment can also be used as a simple mirror in turned off state. With a simple arrangement it can produce experiential spatial and lighting effect, which could be further improved by placing similar equipment side by side, and combining the colours and the shapes.
