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 configured to mount the light to an inner surface of a conduit of a pool or a spa.

2. The light of claim 1 , further comprising a first heat sink, the first heat sink conducting heat away from the electronic assembly.

3. The light of claim 2 , further comprising a second heat sink, the second heat sink having a higher thermal conductivity than the first heat sink.

4. The light of claim 2 , further comprising a water pathway placing the first heat sink in contact with water.

5. The light of claim 1 , wherein the means configured to mount creates a seal with the conduit in which the light is installed.

6. The light of claim 1 , wherein the means configured to mount secures the light within the conduit in which the light is installed.

7. The light of claim 1 , further comprising a cable extending through the rear end of the body and in electrical communication with the electronic assembly, the cable providing power to the electronic assembly.

8. The light of claim 7 , wherein the cable provides control commands to the electronic assembly.

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

10. The light of claim 9 , wherein the electronic assembly wirelessly receives control commands through the wireless transceiver.

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

12. The light of claim 1 , wherein the means configured to mount comprises abrasive teeth for increased pull-out resistance.

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

14. 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.

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

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

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

18. The light of claim 1 , wherein the body is formed using low-pressure over-molding.

19. The light of claim 1 , wherein the means configured to mount is configured to absorb expansion due to freezing water.

20. The light of claim 1 , wherein the means configured to mount comprises a hollow o-ring that can absorb expansion due to freezing water.

21. The light of claim 1 , wherein the means configured to mount is formed of a flexible material that can absorb expansion due to freezing water.

22. The light of claim 1 , wherein the means configured to mount is coated with a flexible material that can absorb expansion due to freezing water.

23. 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.

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

25. The light of claim 24 , wherein the LED is one of a GB LED, RGBW LED, white LED, or ultraviolet LED.

26. The light of claim 1 , wherein the means configured to mount is expandable to form a watertight seal with conduits of varying inner diameter sizes.
