Abstract

The present invention provides a lighting device having a plurality of light source assemblies within a light housing. The light source assemblies include a light emitting diode disposed in tubular lens. The light housing is attached to an edge of the body.

Claims

1. A light box comprising:

a plurality of light source assemblies, each having at least one light emitting diode disposed in a hollow tubular lens;

a rear face including a plurality of channels formed in an interior surface of the rear face and a plurality of cylindrical mounts formed on interior side surfaces of the rear face; and

a front cover coupled to the rear face.

2. The light box of claim 1, the plurality of channels maintain the location of the plurality of light source assemblies when in use.

3. The light box of claim 1, the light source assemblies including spigots insertable into the cylindrical mounts.

4. The light box of claim 1, the channels comprising a shallow, curved in cross section in which can sit the hollow tubular lenses.

5. The light box of claim 1, wherein the interior surface of the rear face is textured to provide a diffuse reflection.

6. The light box of claim 1, further comprising a hanging mechanism.

7. The light box of claim 1, wherein one or more interior surfaces of the rear face are coated with a reflective material.

8. The light box of claim 1, wherein each light source assembly further includes a reflective spigot located on an end of the tubular lens and inserted into the cylindrical mounts.

9. A lighting device comprising:

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

a light box comprising;

a plurality of light source assemblies, each having at least one light emitting diode disposed in a hollow tubular lens;

a rear face including a plurality of channels formed in an interior surface of the rear face and a plurality of cylindrical mounts formed on interior side surfaces of the rear face;

a light transmissive front cover coupled to the rear face; and

an attachment mechanism pivotally attached to the edge of the body.

10. The lighting device of claim 9, the attachment mechanism provides a clamping force in a retracted position to permit attachment of the lighting device on articles.

11. The lighting device of claim 10, the articles comprise one or more of the group comprising a pocket, a belt, a string, and a necklace.

12. The lighting device of claim 9, the light box being movable to a first, retracted position in which the front cover faces the 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.

13. The lighting device of claim 9, the channels comprising a shallow, curved in cross.

14. The lighting device of claim 9, the attachment mechanism being operative to selectively pivot relative to a retracted position.
