DETAILED DESCRIPTION

Conventionally, lighting fixtures are used to produce a desired degree of illumination. Typically, a lighting fixture comprises a visor to block the upward directional light emitted by a plurality of light sources such as LEDs, bulbs etc., fixed to the lighting fixture. However, to fasten the visor to the lighting fixture, a plurality of fasteners is required, which increases the number of apertures to be machined on the visor and on the lighting fixture to accommodate the fasteners. Furthermore, the field installation time of the visor on the lighting fixture increases.

Therefore, there is felt a need for a visor that alleviates the abovementioned drawbacks of conventional visors and prevents the sky glow. The present disclosure envisages a visor for use with a lighting fixture. The visor, of the present disclosure, is hereinafter described with reference to Figure 1 through Figure 5.

Referring to Figure 1 and Figure 5, a visor 100 for use with a lighting fixture 102 comprises a central panel 104, and a pair of side panels 106, wherein the pair of side panels 106 is extended from the operative ends of the central panel 104. Further, at least one connecting portion 108 is extended from each of the central panel 104 and the pair of side panels 106. The connecting portion 108 is configured to facilitate the mounting of the visor 100 on the lighting fixture 102. In an embodiment, the connecting portions 108 are configured centrally on the operative edges of the central panel 104 and pair of side panels 106, thereby forming a three -point contact, and allowing the visor 100 to be rigidly fixed to the lighting fixture 102.

Further, the free operative ends of the connecting portion 108 are hemmed to form a hemmed formation 110, wherein the hemmed formation 110 is configured to provide a link to fit at least one clip 112. The clip 112 is fitted into the hemmed formation 110 to facilitate fastening of the visor 100 on the lighting fixture 102. The hemmed formation 110 strengthens the connecting portions 108 so that the connection portion 108 can support the weight of the visor 100 connected to the lighting fixture 102.

In an embodiment, the clip 112 has a U-shaped profile having connecting legs 113 to securely fix to the lighting fixture 102. Further, the clip 112 has bent portions configured near the free ends of the connecting legs 113. The connecting legs 113 are extended and undergo a spring back action to rigidly hold the visor 100 of the lighting fixture 102. In an embodiment, the visor 100 is snap fitted onto the lighting fixture 102 by means of the clip 112. The clip 112 has smooth extended ends at the connecting legs 113 which facilitate easy sliding of the at least one clip 112, and prevents any damage to the lighting fixture 102. In an embodiment, the clip 112 has any other profile which provides rigid fitment of the visor 100 with the lighting fixture 102.

Further, the clip 112 is pivotable within the hemmed formation 110 of the connecting portions 108. In an embodiment, the angle of rotation of the clip 112 is 320°, which provides pivotable motion to the at least one clip 112 within the hemmed formation 110. Further, the use of the clips 112 for fitting the visor 100 to the lighting fixture 102 eliminates the use of any fasteners, thereby eliminating the use of any tools required to fix the visor 100. Moreover, the installation time and maintenance required for the visor 100 is reduced as compared to the conventional visors. In another embodiment, the at least one clip 112 is replaceable.

Further, the central panel 104 is inclined at a pre-determined angle with respect to a front cover 114 of the lighting fixture 102. In an embodiment, the pre determined angle is 70°. In an exemplary embodiment, the central panel of a conventional visor is inclined at an angle of 90°. The pre-determined angle of the central panel 104 of the visor 100 of the present disclosure is optimized by 20° compared to the conventional visor for the lighting fixture 102. An optimized angle 118 of 20° provides a tilt angle to the visor 100, which maximizes a forward coverage of the light emitted by a plurality of LEDs fixed to the lighting fixture 102. Further, optimizing of the angle of the central panel 104 of the visor 100 also reduces the conventional length 122 of the central panel 104, thereby providing minimal upward waste light illuminated by the LEDs. In an embodiment, the optimized length 120 and optimized angle 118 of the central panel 104 of the present disclosure reduces sky glow (minimal upward waste light) substantially when compared to the conventional visor.

In an embodiment, the central panel 104 and the pair of side panels 106 of the visor 100 are provided with a reflecting surface which enhances the effective utilization of light emitted by the LEDs.

In an embodiment, the connecting portions 108 configured at operative edges of the central panel 104 and the pair of side panels 106 interface with the front cover 114. In an exemplary embodiment, a plurality of notches 124 are provided at the operative edges of the central panel 104 and the pair of side panels 106 to facilitate the fitment of the visor 100 over a guard 116, wherein the guard 116 is disposed between the front cover 114 and the lighting fixture 102.

In an embodiment, the visor 100 comprising the central panel 104, the pair of side panels 106, the connecting portions 108, the hemmed formation 110, the at least one clip 112 and the connecting legs 113 is made of steel. In another embodiment, the visor 100 and the clips 112 of made of any metal or any suitable non-metallic material.

The visor 100, of the present disclosure, provides tool less operation to fit the visor 100 to the lighting fixture 102. Further, the visor 100 also reduces sky glow and enhances the effective utilization of light emitted by the LEDs and the like.
