Abstract

A LED light assembly, the light assembly comprising a reflective plate comprising a plurality of perforations formed therethrough the reflective plate, a plurality of LED bulbs wherein each LED bulb protrudes through a respective perforation of the plurality of perforations, and a control circuit selectively operable to produce a plurality of colored lights through the plurality of LED bulbs wherein the control circuit comprises a switch which when activated a defined number of times produces a plurality of at least light colors and light patterns wherein each of the plurality of at least light colors and light patterns are selected based on the defined number of times the switch is activated.

Claims

1. A heat dissipating LED light assembly for use under water, said light assembly comprising:

a light fixture, comprising;

a reflective plate comprising a plurality of perforations formed through said reflective plate, the reflective plate being configured to reflect heat;

a plurality of LED bulbs wherein the LED bulbs are placed on one side of the reflective plate to protrude through a respective perforation of said plurality of perforations and wherein a portion of the LED bulbs are angled from a horizontal axis to include angles between 15–

70 degrees, based on dimensions of an underwater structure that receives light from the light fixture;

a control circuit selectively operable to produce a plurality of colored lights through said plurality of LED bulbs;

wherein said control circuit comprises a switch which, when activated a defined number of times, produces a plurality of at least light colors wherein said plurality of at least light colors are selected based on said defined number of times said switch is activated.

2. The light assembly of claim 1 wherein one of said plurality of LED bulbs comprises long leads connecting said LED bulb to said control circuit and providing a distance between said LED bulb and said control circuit.

3. The light assembly of claim 2 wherein a sidewall of a perforation of said reflective plate provides support to said leads.

4. The light assembly of claim 2 wherein said reflective plate is a white plate.

5. The light assembly of claim 1 further comprising an Edison-style connector that fits within an Edison-style electric base.

6. The light assembly of claim 5 wherein said light assembly comprises a body comprising a plurality of symmetrically-shaped portions decreasing in size starting at said reflective plate and ending at said Edison-style connector.

7. The light assembly of claim 1 wherein said light assembly is operable with at least one of 12 volts and 24 volts.

8. The light assembly of claim 1 wherein said control circuit is held in place in said light assembly with a thermal conductive epoxy.

9. The light assembly of claim 1 wherein each LED bulb in said plurality of LED bulbs is operable to illuminate in a plurality of colors.

10. The light assembly of claim 1 wherein a LED bulb of said plurality of LED bulbs ranges in power from 1 to 5 watts.

11. The light assembly of claim 1, wherein the light fixture further comprises slots that enable water to flow behind the LED bulbs, between the light fixture and a mounting surface.

12. The light assembly of claim 11, further comprising a mounting structure that secures the light fixture, wherein the mounting structure includes at least one slot that enables water to pass behind the LED bulbs, between the mounting structure and the light fixture.

18. The light assembly of claim 1 wherein at least one LED bulb of said plurality of LED bulbs is angled from 0 to 75 degrees from the horizontal axis.

20. The light assembly of claim 1, wherein said switch when activated a defined number of times further produces a plurality of light patterns wherein each of said plurality of light patterns are selected based on said defined number of times said switch is activated.

13. A heat dissipating LED light assembly that includes a light fixture for use under water in a pool of water that is operable to replace an incandescent light in an existing niche pool lighting assembly, said LED light assembly comprising:

a light fixture comprising;

a body comprising a first end and a second end wherein a plurality of symmetrically-shaped stair-step portions decreasing in size from said first end to said second end are formed between said first end and said second so as to be similar in size and shape to a standard incandescent lamp bulb;

a reflective plate connected to said first end comprising a plurality of perforations formed through said reflective plate, the reflective plate being configured to reflect heat;

a plurality of LED bulbs wherein each LED bulb is placed on one side of the reflective plate to protrude through a respective perforation of said plurality of perforations and wherein a portion of the LED bulbs are angled from a horizontal axis to include angles between 15–

70 degrees, based on dimensions of an underwater structure that receives light from the light fixture;

an Edison-style connector connected to said second end;

a control circuit selectively operable to produce a plurality of colored lights through said plurality of LED bulbs; and

wherein said control circuit comprises a switch which when activated a defined number of times produces a plurality of at least one of light colors and light patterns wherein each of said plurality of at least one of light colors and light patterns are selected based on said defined number of times said switch is activated.

14. The light assembly of claim 13 wherein said reflective plate is a white plate.

15. The light assembly of claim 13 wherein said reflective plate insulates said control circuit from heat dissipated by said plurality of LED bulbs.

16. The light assembly of claim 13 wherein said plurality of LED bulbs are dispersed at a plurality of angles to minimize reflectivity from an interior surface liner of said pool of water.

17. The light assembly of claim 13 wherein said plurality of LED bulbs are dispersed at a plurality of beam angles.

19. The light assembly of claim 13 wherein at least one LED bulb of said plurality of LED bulbs is angled from 0 to 75 degrees from a horizontal axis.

21. The light assembly of claim 13, wherein the light fixture further comprises slots that enable water to flow behind the LED bulbs, between the light fixture and a mounting surface.

22. The light assembly of claim 21, further comprising a mounting structure that secures the light fixture, wherein the mounting structure includes at least one slot that enables water to pass behind the LED bulbs, between the mounting structure and the light fixture.
