Abstract

Embodiments of the disclosure provide a system for selecting a color show generated by LED landscape, pool, and/or spa lights. The system can include an overlay indicating the color shows available to select from. A selector adjacent to the overlay can be positioned to select one of the color shows. The system includes a microcontroller in communication with the selector and a triac circuit in communication with the microcontroller. The microcontroller controls the LED landscape, pool, and/or spa lights using the triac circuit in response to the position of the selector.

Claims

1. A system for selecting one of a plurality of color shows generated by at least one of light emitting diode landscape, pool, and spa lights, the system comprising:

an overlay indicating the plurality of color shows available to select from;

a selector adjacent to the overlay positioned to select one of the plurality of color shows;

a microcontroller in communication with the selector; and

a triac circuit in communication with the microcontroller, the microcontroller controlling the at least one of light emitting diode landscape, pool, and spa lights using the triac circuit in response to the position of the selector.

2. The system of claim 1 and further comprising a recall switch in communication with the microcontroller, wherein the overlay includes a recall switch selection area in communication with the recall switch and the microcontroller controls the at least one of light emitting diode landscape, pool, and spa lights using the triac circuit in response to the status of the recall switch.

3. The system of claim 1 and further comprising a hold switch in communication with the microcontroller, Wherein the overlay includes a hold switch selection area in communication with the hold switch and the microcontroller controls the at least one of light emitting diode landscape, pool, and spa lights using the triac circuit in response to the status of the hold switch.

4. The system of claim 1 and further comprising a current sensing circuit in communication with the microcontroller and the microcontroller controls the at least one of light emitting diode landscape, pool, and spa lights using the triac circuit in response to the current sensing circuit.

5. The system of claim 1 and further comprising a front cover coupled to a rear cover forming an enclosure, wherein the overlay is coupled to the front cover and the microcontroller is housed within the enclosure.
