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 swimming pool light assembly, said light assembly comprising:

(a) a plate comprising a plurality of perforations and a plurality of edges;

(b) a plurality of LED bulbs wherein each LED bulb protrudes through a respective perforation of said plurality of perforations;

(c) a plurality of sidewall segments wherein each respective sidewall segment is attached to a respective edge of said plate; and

(d) a plurality of slots formed therethrough a sidewall segment of said plurality of sidewalls, wherein water flows through the plurality of slots to dissipate heat generated from the plurality of LED bulbs.

2. The light assembly of claim 1 further comprising a transparent lens covering said plurality of LED bulbs and providing a water-tight seal.

3. The light assembly of claim 1 further comprising a mounting bracket operable to connect said pool light assembly to a side of said swimming pool, wherein the mounting bracket includes attachment fixtures between the plurality of slots that do not obstruct the flow of water through the plurality of slots.

4. The light assembly of claim 3 further comprising a protective surface attachment placed between said mounting bracket and said side of said swimming pool.

5. The light assembly of claim 1 further comprising a control circuit selectively operable to illuminate a plurality of colored lights through said plurality of LED bulbs.

6. The light assembly of claim 5 wherein said 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 said plurality of at least light colors and light patterns are based on said defined number of times said switch is activated.

7. The light assembly of claim 5 wherein said control circuit is located at a location remote from said swimming pool and connectors provide control signals to said light assembly.

8. The light assembly of claim 1 wherein each LED bulb in said plurality of LED bulbs is operable at a low voltage approximately between 12 and 24 volts to illuminate in a plurality of colors.
