Abstract

A lighting device includes a lens portion and a base portion. The lens portion includes at least one light-distributing void for distributing light throughout the lens portion. The base portion includes a light source for emitting light into the lens portion.

Claims

1. A lighting device comprising:

a lens portion having a predetermined shape and an extended portion having at least one of an embossed rim or debossed rim, said lens portion comprising at least one light-distributing void to help distribute light throughout said lens portion for emitting the light outside of the entirety of the lighting device; and

a base portion configured to mate with said lens portion, said base portion having a cavity having at least one of an embossed rim and a debossed rim that corresponds to said at least one embossed rim and debossed rim of the extended portion for removing and securing said extended portion within the cavity, said base portion comprising a light source for emitting light into said lens portion.

2. A lighting device according to claim 1 wherein said lens portion comprises a first void having a predetermined size and shape and a second void having a predetermined size and shape, said second void being positioned at a predetermined distance and at a predetermined angle from said first void.

3. A lighting device according to claim 1 wherein said lens portion comprises a first void having a predetermined size and shape, a second void having a predetermined size and shape, said second void being positioned at a predetermined distance and at a predetermined angle from said first void, and a third void having a predetermined size and shape, said third void being positioned at a predetermined distance and at a predetermined angle from at least one of said first void and said second void.

4. A lighting device according to claim 1, wherein said lens portion comprises a plurality of light-distributing voids.

5. A lighting device according to claim 4, wherein said plurality of light-distributing voids comprises light-distributing voids of at least two different shapes.

6. A lighting device according to claim 4, wherein at least one of said light-distributing voids directs at least a portion of the light emitted by said light source toward at least another of said light-distributing voids.

7. A lighting device according to claim 1, comprising one or more batteries for supplying power to said light sources.

8. A lighting device according to claim 7, comprising one or more solar panels for charging said one or more batteries.

9. A lighting device according to claim 1, wherein said lens portion comprises a transparent plastic material.

10. A lighting device according to claim 1, wherein said lens portion comprises a translucent plastic material.

11. A lighting device according to claim 1, wherein said light-distributing void has a triangular shape.

12. A lighting device according to claim 1, wherein said light-distributing void has a diamond-like shape.

13. A lighting device according to claim 1, wherein said light-distributing void has a hexagonal shape.

14. A lighting device according to claim 1, wherein said light-distributing void has a round shape.

15. A lighting device according to claim 1, wherein said light-distributing void has a diamond-like shape with a 2:

1 height to width ratio.

16. A lighting device according to claim 1, wherein said light source comprises a light emitting diode.

17. A method of making a lighting device comprising:

forming a lens of a predetermined shape from a transparent or translucent material, said lens having an extended portion having at least one of an embossed rim and a debossed rim;

including in the lens one or more void areas having a predetermined shape, the one or more voids being positioned within the lens to help distribute light throughout substantially the entire lens;

forming a base portion configured to mate with the extended portion, said base portion having a cavity having at least one of an embossed rim and a debossed rim that corresponds to said at least one embossed rim debossed rim of the extended portion;

providing a light source in said base portion; and

inserting the extended portion into the base portion.

18. A method according to claim 17, wherein forming the lens includes one or more voids having a triangular shape.

19. A method according to claim 17, wherein forming the lens includes one or more voids having a diamond-like shape.

20. A method according to claim 17 wherein the step of including in the lens one or more voids comprises a first void having a predetermined size and shape and a second void having a predetermined size and shape, the second void being positioned at a predetermined distance and angle from the first void.

21. A method according to claim 17 wherein the step of including in the lens one or more void comprises a first void having a predetermined size and shape, a second void having a predetermined size and shape, the second void being positioned at a predetermined distance and angle from the first void, and a third void having a predetermined size and shape, the third void being positioned at a predetermined distance and angle from at least one of the first void and second void.
