Abstract

The present invention provides a lighting device having a light housing including a light source being rotatably connected by a rotatable connection means to a lighting device body, said body having said rotatable connection means positioned so as to allow said light housing to lay adjacent said body and to define therebetween a narrow space which is accessible in a base to top direction.

The present invention also provides a light housing for a lighting device, said light housing including a light source holder at one end thereof, said light housing also including means to receive a mounting member at one end of said light housing opposite to said light source holder, said light housing being characterised by said light source holder allowing limited pivotal movement of said light source when said light source is mounted in said light source holder, said limited pivotal movement being in the range of 5° to 30°.

The present invention further provides a method of assembling a light housing as claimed in any one of the preceding claims, said method including the steps of: attaching said cover to said box; inserting said tubular lens through said aperture; engaging said spigot with one end of said tubular lens; inserting said lighting source into the second end of said tubular lens; and securing said light source to said housing.

The present invention also provides light housing for a lighting device, said light housing including a first and second face and sides there around, a first side having a mounting spigot to receive one end of a tubular lens, and a second side opposite to said first side having an aperture therethrough, through which aperture tubular lens can pass and in which is received the other end of said tubular lens, said aperture and said mounting spigot being aligned.

Claims

1. A lighting device comprising:

a lighting device body containing a battery compartment, said lighting device body having an edge;

a lighting housing having a rear face and a forward cover, said light housing enclosing a plurality of light source assemblies;

wherein each light source assembly includes at least one light emitting diode, which is disposed in a hollow tubular lens of the light source assemblies; and

wherein the light housing is rotatably attached to the edge of the lighting device body.

2. The lighting device of claim 1, wherein the lighting device body comprises a removable cover to give access to the battery compartment.

3. The lighting device of claim 1, wherein a surface of the rear face is textured to provide a diffuse reflection.

4. The lighting device of claim 1, wherein the lighting device body is of a rectangular prismatic shape.

5. The lighting device of claim 1, further comprising a slot coupled to the body.

6. The lighting device of claim 5, wherein the slot is attachable to a rope.

7. The lighting device of claim 1, further comprising a hanging mechanism coupled to the body.

8. The lighting device of claim 1, further comprising a foot coupled to the body.

9. The lighting device of claim 1, wherein the rotatable attachment of the light housing to the body is provided with a degree of resistance.

10. The lighting device of claim 1, wherein the rotatable attachment of the light housing to the body provides a clamping force between the light housing and the body.

11. The lighting device of claim 10, wherein the clamping force holds the device in place on a pocket.

12. The lighting device of claim 1, wherein the forward face of the light housing can be selectively repositioned between 180°

and 225°

relative to a retracted position.

13. The lighting device of claim 1 further comprising at least one raised projection on along the terminal mounting edge to provide a locking bias to releasably hold the light housing in a retracted position.

14. The lighting device of claim 1, wherein one or more interior surfaces of the rear face are coated with a reflective material.

15. The lighting device of claim 1, wherein each light source assembly further includes a reflective spigot located on an end of the tubular lens.

18. The lighting device of claim 13, wherein the light housing is movable to a first, retracted position in which the forward cover faces the lighting device body and to a second, open position in which the forward cover is located at an angle between 180°

and 225°

relative to the first position.

16. A lighting device comprising:

a lighting device body containing a battery compartment, said lighting device body having an edge;

a lighting housing having a rear face and a light transmissive forward cover, wherein the lighting housing is attached to the edge;

a tubular, light transmissive lens disposed in the lighting housing, wherein the lens includes first and second opposing sides respectively with openings into the lens; and

first and second light emitting diodes respectively disposed in the openings of the lens.

17. The lighting device of claim 16, wherein the device is hung from an article of clothing to allow reading.

19. A lighting device, comprising:

a body, including;

an edge; and

a battery compartment that receives a battery;

a light source assembly, including;

a light emitting diode and a hollow tubular lens, wherein the light emitting diode is partially disposed in the hollow tubular lens; and

a lighting housing, including;

a rear face; and

a forward cover, wherein the lighting housing encloses the light source assembly and rests against the body in a retracted position.

20. The device of claim 21, wherein the light housing is pivotably attached to the edge so as to selectively pivot relative to the retracted position.
