Abstract

A light includes a body, a front housing secured to a front end of the body, a translating retainer rotatably engaged with the front housing, a slip ring positioned around the front housing and between the translating member and the front end of the body, a compressible ring positioned around the front housing and between the slip ring and the front end of the body, a lens mounted to the front housing, an electronic assembly, and a light emitting element in electrical communication with the electronic assembly and positioned within the lens. Rotation of the translating retainer in a first direction causes the translating retainer to drive the slip ring toward the front end of the body, compressing the compressible ring and causing the compressible ring to bulge outward to contact, and removably engage, an inner wall of a pipe or conduit that the light is positioned in.

First claim

What is claimed is:

1. A light, comprising:
a body having a front end and a rear end;
a lens coupled to the body, wherein the body and the lens define a waterproof chamber;
an electronic assembly mounted in the waterproof chamber, the electronic assembly including at least one light-emitting element for emitting light; and
means for mounting the light to an inner surface of a conduit, the conduit including an electrical cable for supplying electrical current to the light, wherein the means for mounting comprises:
a front housing secured to the front end of the body;
a translating retainer rotatably engaged with the front housing;
a slip ring positioned around the front housing and between the translating retainer and the front end of the body; and
a compressible ring positioned around the front housing, and between the slip ring and the front end of the body,
wherein rotation of the translating retainer with respect to the lens in a first direction causes the translating retainer to drive the slip ring toward the front end of the body, compressing the compressible ring between the slip ring and the front end of the body, and causing the compressible ring to bulge outward.

2. The light of claim 1 , wherein the compressible ring includes abrasive teeth for increased pull-out resistance.

3. The light of claim 1 , wherein the compressible ring comprises a barbed element.

4. The light of claim 1 , wherein the compressible ring comprises an o-ring.

5. The light of claim 1 , wherein the compressible ring comprises an adhesive.

6. The light of claim 5 , wherein the adhesive is silicone based.

7. The light of claim 1 , wherein the compressible ring secures to the inner diameter of a pipe or electrical conduit.

8. The light of claim 1 , wherein the compressible ring forms a watertight seal with the inner diameter of the conduit.

9. The light of claim 1 , wherein the compressible ring is expandable to form a watertight seal with conduits of varying inner diameter sizes.

10. The light of claim 1 , wherein the translating retainer secures to a front face of the conduit.

11. The light of claim 1 , further comprising a first heat sink secured to the front end of the body, and in thermal communication with the electronic assembly, wherein the first heat sink dissipates heat away from the electronic assembly.

12. The light of claim 11 , further comprising a second heat sink, the second heat sink having a higher thermal conductivity than the first heat sink.

13. The light of claim 11 , further comprising a water pathway placing the first heat sink in contact with water.

14. The light of claim 1 , wherein the cable provides control commands to the electronic assembly.

15. The light of claim 1 , wherein the electronic assembly includes a wireless transceiver.

16. The light of claim 15 , wherein the electronic assembly wirelessly receives control commands through the wireless transceiver.

17. The light of claim 1 , wherein the light can be installed in a wall bulk head fitting.

18. The light of claim 1 , wherein the light can be installed in a dry environment.

19. The light of claim 1 , wherein the light can be installed in a wet environment.

20. The light of claim 1 , wherein the light can be installed in a wet environment and a dry environment.

21. The light of claim 1 , wherein a thermally conductive potting compound encapsulates the electronic assembly.

22. The light of claim 1 , wherein the lens includes an optic for directional control of emitted light.

23. The light of claim 1 , further comprising an adjustable reflective optic for directional control of emitted light.

24. The light of claim 1 , further comprising a heat-pipe that conducts heat from the electronic assembly and the light emitting element, and spreads the heat evenly throughout the body.

25. The light of claim 1 , wherein the electronic assembly comprises a plurality of printed circuit boards mated using stand-off connectors.

26. The light of claim 1 , wherein the electronic assembly comprises a plurality of printed circuit boards mated using edge card connections.

27. The light of claim 1 , wherein the electronic assembly comprises a plurality of printed circuit boards mated using a flex tail.

28. The light of claim 1 , wherein the compressible ring is configured to absorb expansion due to freezing water.

29. The light of claim 1 , wherein the compressible ring comprises a hollow o-ring that can absorb expansion due to freezing water.

30. The light of claim 1 , wherein the compressible ring is formed of a flexible material that can absorb expansion due to freezing water.

31. The light of claim 1 , wherein the compressible ring is coated with a flexible material that can absorb expansion due to freezing water.

32. The light of claim 1 , further comprising a thermal management system in communication with the electronic assembly, the thermal management system preventing operation of the electronic assembly and the light emitting element at an operational temperature exceeding component limitations.

33. The light of claim 1 , wherein the lens includes one or more apertures configured to be engaged by a stationary tool for securing the lens, and the means for mounting includes one or more slots configured to be engaged by a rotating tool for rotating a portion of the means for mounting.

34. The light of claim 33 , wherein the stationary tool and the rotating tool are adapted to interface with at least one of a screwdriver, wrench, ratchet, or drill.

35. The light of claim 1 , wherein the light emitting element is an LED.

36. The light of claim 35 , wherein the LED is one of a RGB LED, RGBW LED, white LED, or ultraviolet LED.

37. A light, comprising:
a body having a front end and a rear end;
a lens coupled to the body, wherein the body and the lens define a waterproof chamber;
an electronic assembly mounted in the waterproof chamber, the electronic assembly including at least one light-emitting element for emitting light; and
means for mounting the light to an inner surface of a conduit, the conduit including an electrical cable for supplying electrical current to the light, wherein the means for mounting comprises:
a front housing secured to the front end of the body;
a translating retainer rotatably engaged with the front housing;
a slip ring positioned around the front housing and between the translating retainer and the front end of the body; and
a compressible ring positioned around the front housing, and between the slip ring and the front end of the body,
wherein rotation of the lens with respect to the translating retainer in a first direction causes the translating retainer to drive the slip ring toward the front end of the body, compressing the compressible ring between the slip ring and the front end of the body, and causing the compressible ring to bulge outward.

38. The light of claim 37 , wherein the compressible ring includes abrasive teeth for increased pull-out resistance.

39. The light of claim 37 , wherein the compressible ring comprises a barbed element.

40. The light of claim 37 , wherein the compressible ring comprises an o-
