Abstract

A lighting device is disclosed. The lighting device can include a light bar and a base having an elongated groove shaped to receive the light bar. The light bar can be rotatable relative to the base around an axis substantially perpendicular to the long axis of the light bar. Rotation of the light bar around this axis can move the light bar into and out of the elongated groove, thus converting the lighting device between compact and expanded configurations. For greater maneuverability, the light bar can include a light source housing portion rotatable around an axis substantially parallel to the long axis of the light bar. The light source housing portion can include two or more light emitting diodes positioned along the long axis of the light bar. The lighting device can be used with a mounting sleeve shaped to receive, for example, one end of the base.

Claims

1. A lighting device, comprising:

a base having an elongated groove with a first end and a second end; and

an elongated light bar, wherein the elongated light bar includes a hinged connection to the base, the hinged connection is positioned closer to the first end of the elongated groove than to the second end of the elongated groove, the elongated light bar is rotatable at the hinged connection around a first rotation axis substantially perpendicular to a long axis of the elongated light bar, a light source housing portion of the elongated light bar is rotatable around a second rotation axis substantially parallel to the long axis of the elongated light bar, and the lighting device is convertible into a compact configuration with at least a portion of the elongated light bar positioned within the elongated groove.

2. The lighting device according to claim 1, wherein the hinged connection is positioned within the elongated groove.

3. The lighting device according to claim 1, wherein the base is elongated and the long axis of the elongated light bar is substantially parallel to a long axis of the base when the lighting device is in the compact configuration.

4. The lighting device according to claim 1, wherein rotation of the elongated light bar around the first rotation axis is restricted to a range of less than about 180 degrees.

5. The lighting device according to claim 1, wherein rotation of the light source housing portion around the second rotation axis is restricted to a range of less than about 360 degrees.

6. The lighting device according to claim 1, wherein the base includes a battery compartment.

7. The lighting device according to claim 1, wherein the base includes a DC power port.

8. The lighting device according to claim 1, wherein the base has a first end and a second end, the second end of the base is adjacent to the second end of the elongated groove, and the lighting device further comprises a hook adjacent to the first end of the base.

9. The lighting device according to claim 8, wherein the hook is rotatable into a hook recess within the base.

10. The lighting device according to claim 1, wherein the light source housing portion includes two or more light emitting diodes positioned along the long axis of the elongated light bar.

11. The lighting device according to claim 10, wherein the light emitting diodes are positioned behind a substantially transparent window, and the length of the substantially transparent window is between about 50% and about 100% of the length of the elongated light bar.

12. The lighting device according to claim 1, wherein the second end of the elongated groove is open such that the second end of the elongated light bar is exposed when the lighting device is in the compact configuration.

13. The lighting device according to claim 12, wherein a portion of the elongated light bar projects beyond the second end of the elongated groove when the lighting device is in the compact configuration.

14. A lighting device kit, comprising:

a lighting device including a base having an elongated groove with a first end and a second end, and an elongated light bar; and

a mounting sleeve, wherein the elongated light bar includes a hinged connection to the base, the hinged connection is positioned closer to the first end of the elongated groove than to the second end of the elongated groove, the elongated light bar is rotatable at the hinged connection around a first rotation axis substantially perpendicular to a long axis of the elongated light bar, a light source housing portion of the elongated light bar is rotatable around a second rotation axis substantially parallel to the long axis of the elongated light bar, the lighting device is convertible into a compact configuration with at least a portion of the elongated light bar positioned within the elongated groove, and the lighting device is configured to slide into or out of the mounting sleeve without the use of tools.

15. The lighting device kit according to claim 14, wherein the base has a first end and a second end, the second end of the base is adjacent to the second end of the elongated groove, and the mounting sleeve is configured to receive the first end of the base.

16. The lighting device kit according to claim 14, wherein the mounting sleeve includes an opening, and rotation of the elongated light bar around the first rotation axis causes a portion of the elongated light bar to move into the opening.

17. The lighting device kit according to claim 14, wherein the lighting device kit further comprises an electrical adaptor configured to electrically connect the lighting device to an electrical receptacle.

18. A lighting device, comprising:

a base having an elongated groove;

an elongated light bar;

first hinge means for allowing the elongated light bar to rotate relative to the base around a first rotation axis substantially perpendicular to a long axis of the elongated light bar; and

second hinge means for allowing a light source housing portion of the elongated light bar to rotate relative to the base around a second rotation axis substantially parallel to the long axis of the elongated light bar, wherein the lighting device is convertible into a compact configuration with at least a portion of the elongated light bar positioned within the elongated groove.

19. The lighting device according to claim 18, further comprising power means for providing power to lighting elements positioned within the light source housing portion.

20. The lighting device according to claim 18, further comprising mounting means for attaching the lighting device to amounting surface.
