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 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.

2. The lighting device of claim 1, the attachment mechanism provides a clamping force in a retracted position to permit attachment of the lighting device on articles.

3. The lighting device of claim 2, the articles comprise one or more of the group comprising a pocket, a belt, a string, and a necklace.

4. The lighting device of claim 1, 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.

5. The lighting device of claim 1, the channels comprising a shallow, curved in cross.

6. The lighting device of claim 1, the attachment mechanism being operative to selectively pivot relative to a retracted position.

7. The lighting device of claim 1, wherein the plurality of light source assemblies are disposed in the plurality of channels.

8. The lighting device of claim 7, wherein each channel comprises a cylindrical portion formed in the interior surface of the rear face and configured to receive a hollow tubular lens of a light source assembly.

9. The lighting device of claim 7, wherein the plurality of light source assemblies are held by the plurality of cylindrical mounts.

10. The lighting device of claim 1, wherein the plurality of light source assemblies are disposed in the plurality of curved channels such that the plurality of channels seat the light source assemblies.

11. 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, wherein the plurality of light source assemblies are disposed in the plurality of curved channels such that the plurality of channels seat the light source assemblies; and

a light transmissive front cover coupled to the rear face.

12. The lighting device of claim 11 further comprising the attachment mechanism pivotally attached to the edge of the body.
