Abstract

The present invention includes a collapsible lighting device comprising: (a) a container having a base portion and optional lid portion, that is adapted to be reversibly moved from a closed position to an open position; (b) at least one light source disposed in the container; and (c) a collapsible envelope of a diffuser material disposed in the container, and adapted to be reversibly moved from a contained position defining a contained volume within the container when the container is in the closed position, to a deployed position when the container is in the open position.

Claims

1. A collapsible lighting device comprising:

a. a container having a base portion and a lid portion, said portions adapted to contain an initial volume and adapted to be reversibly moved from a closed position to an open position;

b. at least one light source disposed in said container; and

c. a collapsible envelope of a diffuser material disposed in said container, and adapted to be reversibly moved from a contained position defining a contained volume within said container when said container is in said closed position, to a deployed position wherein said collapsible envelope of a diffuser material defines a volume greater than said contained volume and extending outside said container, when said container is in said open position.

2. A lighting device according to claim 1, additionally comprising a frame adapted to be reversibly moved from a closed position to an open position, and to maintain said collapsible envelope of a diffuser material in said deployed position when said container is in said open position, said frame adapted to be collapsed into said container when said container is in said closed position.

3. A lighting device according to claim 2, wherein said frame comprises a plurality of hinged panels attached to said container so as to be adapted to be collapsed into said container when said container is in said closed position.

4. A lighting device according to claim 1 wherein said collapsible envelope of a diffuser material in said deployed position has a cylindrical shape around said at least one light source.

5. A lighting device according to claim 1, wherein said base and lid portions comprise a translucent plastic material.

6. A lighting device according to claim 1 wherein said container is adapted to be attached to a pole.

7. A lighting device according to claim 1 wherein said container additionally comprises a hook.

8. A lighting device according to claim 1 wherein said lid portion additionally comprises a handle.

9. A lighting device according to claim 1 wherein said base portion additionally comprises a retractable base extension.

10. A lighting device according to claim 1 wherein said diffuser material is releasably attached to said container.

11. A collapsible lighting device comprising:

a. a container having a base portion and a lid portion, wherein said base and lid portions are of a translucent plastic material and are adapted to contain a space when closed upon one another;

b. at least one light source disposed in said container; and

c. a collapsible envelope of a diffuser material disposed in said base portion, and adapted to be reversibly moved from a contained position within said space contained by said base and lid portions, to a deployed position upon opening said lid portion.

12. A collapsible lighting device comprising:

a. a container having a base portion and a lid portion, each said portion having a concave disk shape and adapted to contain an initial volume and adapted to be reversibly moved from a closed position to an open position;

b. at least one light source disposed in said container; and

c. a collapsible envelope of a diffuser material disposed in said container, and adapted to be reversibly moved from a contained position defining a contained volume within said container when said container is in said closed position, to a deployed position wherein said collapsible envelope of a diffuser material defines a volume greater than said contained volume and extending outside said container, when said container is in said open position, said collapsible envelope of a diffuser material having a substantially cylindrical shape.

13. A lighting device according to claim 12 wherein said collapsible envelope of a diffuser material in said deployed position has a cylindrical shape around said at least one light source.

14. A lighting device according to claim 12, additionally comprising at least one hinged support adapted to be reversibly moved from a closed position to an open position, and to maintain said collapsible envelope of a diffuser material in said deployed position when said container is in said open position, said hinged support adapted to be collapsed into said container when said container is in said closed position.

15. A lighting device according to claim 12, wherein said base and lid portions comprise a translucent plastic material.

16. A lighting device according to claim 12, wherein said at least one hinged support is attached to said portions, so as to be adapted to be collapsed into said container when said container is in said closed position.

17. A lighting device according to claim 12, additionally comprising at least one hinged support adapted to be reversibly moved from a closed position to an open position, and to maintain said collapsible envelope of a diffuser material in said deployed position when said container is in said open position, said hinged support adapted to be collapsed into said container when said container is in said closed position, and wherein said at least one light source comprises a light bulb mounted on said hinged support.

18. A lighting device according to claim 12 wherein said container is adapted to be attached to a pole.

19. A lighting device according to claim 12 wherein said container additionally comprises a hook.

20. A lighting device according to claim 12 wherein said lid portion additionally comprises a handle.

21. A lighting device according to claim 12 wherein said base portion additionally comprises a retractable base extension.

22. A lighting device according to claim 12 wherein said diffuser material is releasably attached to said container.
