Abstract

A light includes a magnetic base; a light housing having a plurality of LEDs and a DC power source; and a frictional pivot connection between the magnetic base and the light housing.

Claims

1. A light comprising:

a magnetic base;

a light housing having a plurality of LEDs and a DC power source; and

a frictional pivot connection between the magnetic base and the light housing.

2. The apparatus of claim 1, wherein said DC power source is rechargeable.

3. The apparatus of claim 1, further comprising an AC power adapter/recharger for providing AC power to said plurality of LEDs and for recharging said DC power source.

4. The apparatus of claim 1, further comprising a switch for controlling a level of light output by the LEDs.

5. The lighting assembly according to claim 1, wherein the LEDs are high intensity white light LEDs.

6. The apparatus of claim 1, wherein the fictional pivot connection comprises a pivot post pivotally received in a receptacle, and a spring biased piston in the receptacle ad exerting a holding force on the pivot post.

7. The apparatus of claim 6, wherein the receptacle is defined by at least two upstanding walls.

8. The apparatus of claim 7, wherein the at least two upstanding walls define a gap, and wherein the pivot post can pivot along the gap relative to the base.

9. The apparatus of claim 6, wherein the receptacle is rotatable relative to the base, and wherein the pivot post is pivotable relative to the receptacle.

10. The apparatus of claim 6, wherein the piston has an end to correspond to an end shape of the pivot post.

11. The apparatus of claim 8, wherein the spring holds the pivot post in a position relative to the base by biasing the piston against the end of the pivot post.

12. The apparatus of claim 7, wherein the upstanding walls have curved inner surfaces closely matched to the shape of the pivot post.

13. The apparatus of claim 1, wherein the magnetic base comprises a magnet, and wherein the strength of the magnet is 5 to 10 lbs.

14. The apparatus of claim 1, wherein the base is composed of acrylonitrile butadiene styrene (ABS) plastic resin.

15. The apparatus of claim 1, wherein the magnetic base is composed of a rubber.

16. The apparatus of claim 1, wherein the housing is composed of a material selected from the group consisting of color anodized aluminum, ABS, and mixtures thereof.

17. The apparatus of claim 1, wherein the pivot post is composed of a material selected from the group consisting of nylon resin, steel alloy or combinations thereof.

18. The apparatus of claim 1, further comprising a transparent housing top covering the LEDs.

19. The apparatus of claim 6, further comprising a washer between the pivot post and the piston.

20. The apparatus of claim 19, wherein the washer is rubber
