Abstract

A lighting device ( 10 ) having a base housing ( 12 ) to receive one or more batteries therein to power a light source located in a light housing ( 14 ). The light housing ( 14 ) being pivotally attached to the base housing ( 12 ) at pivot points on both sides of the base housing ( 12 ), wherein a handle ( 24 ) is provided which extends along the axis of rotation ( 13 ) between the pivot points.

First claim

What is claimed is:

1. A lighting device comprising a base housing to receive one or more batteries therein to power a light source located in a light housing, the light housing being pivotally attached to said base housing at pivot points on both sides of said base housing; a tubular handle extending along the axis of rotation in between said pivot points; and a printed circuit board (PCB) having at least one light emitting diode (LED) thereon, and a lens with a planar section extending away from the at least one LED, and the at least one LED is arranged so as to emit light into an edge of the lens.

2. The lighting device as claimed in claim 1 wherein said base housing and said light housing each include a body and at least one arm extending from opposed sides of the respective body.

3. The lighting device as claimed in claim 1 wherein said tubular handle is formed on said base housing.

4. The lighting device as claimed in claim 1 wherein said light housing is positioned between a front portion and a rear portion of said base housing.

5. The lighting device as claimed in claim 1 wherein said tubular handle includes a mechanism configured to secure a portion of a handle covering material thereon.

6. The lighting device as claimed in claim 1 wherein said base housing is pivotally secured to a stand when assembled.

7. The lighting device as claimed in claim 1 wherein the lighting device is a hand-held device.

8. A light panel assembly for a portable lighting device, said light panel assembly comprising: a printed circuit board (PCB) having at least one light emitting diode (LED) thereon, and a substantially planar thin lens extending away from said at least one LED, said at least one LED being arranged so as to emit light into an edge of said lens, wherein the lens includes a flange extending along an outer periphery of said lens away from said edge to emit light from said light panel assembly.

9. The light panel assembly of claim 8 , wherein the lens includes at least one recess to receive said at least one LED and said PCB.

10. The light panel assembly as claimed in claim 9 wherein said light source includes a recess for each LED on said PCB.

11. The light panel assembly as claimed in claim 8 further comprising a heat sink attached to said PCB.

12. The light panel assembly as claimed in claim 8 wherein said heat sink includes one or more projections thereon that extend towards said lens.

13. The light panel assembly as claimed in claim 8 wherein said lens includes a respective recess for each projection on said heat sink.

14. The light panel assembly as claimed in claim 13 wherein each respective recess is included in a bight formed along an edge of said lens.

15. The light panel assembly as claimed in claim 8 wherein said lens includes an array of dots or shapes etched thereon to assist in the reflection or transmission or emission of light from the lens.

16. The light panel assembly as claimed in claim 8 wherein said lens is cantilevered in said light housing.

17. The light panel assembly as claimed in claim 13 wherein each respective recess is located in a bight.

18. The light panel assembly as claimed in claim 17 , wherein securing apertures are located at either side of said bight.

19. The light panel assembly as claimed in claim 8 wherein a seal is provided between the light housing surface and a surface of said lens.

20. The light panel assembly as claimed in claim 19 wherein said seal extends across a portion of the width of said lens in the vicinity of said PCB and LEDs.

21. The light panel assembly as claimed in claim 8 wherein the light panel is configured to be placed in the hand-held lighting device.

22. A lighting panel for a portable lighting device, said lighting panel configured as a lens having at least one exposed planar surface forming a substantial portion of the lighting panel for emitting light from the portable lighting device and said exposed planar surface having a periphery defined collectively by a light incident edge and one or more free edges, said lighting panel including around its periphery a flange extending in a lateral direction away from the planar surface, wherein each free edge of said lighting panel includes said flange which extends away from said light incident edge.

23. The lighting panel as claimed in claim 22 wherein said lighting panel includes a front planar surface and a rear planar surface and said flange extends in opposed directions away from said front planar surface and said rear planar surface.

24. The lighting panel as claimed in claim 22 wherein a cross section of a portion of the lighting panel has one of an L-shaped configuration, a T-shaped configuration, an H-shaped configuration or an I-shaped configuration.

25. The lighting panel as claimed in claim 22 wherein said flange defines a curved terminal edge.
