Abstract

An instantly controllable LED light apparatus provides an LED array (34) formed of red, green and blue LEDs in a regular arrangement. The apparatus also provides a unitary power supply/controller (4) disposed within a unitary housing (20) that is coupled only to the LED array (34) and a power source (56) in one embodiment. The power supply/controller (4) includes a memory device (64) such that, when a button (62) is pressed on the control panel (18) of the power supply/controller (4), a desired illumination color is instantly produced by the combination of the red, green and blue LEDs of the LED array (34).

Claims

1-26. -26. (Cancelled)

27. A lighting apparatus comprising:

a plurality of LEDs defining an array of LEDs including more than one different colored group of LEDs; and

an integral power supply/controller unit disposed within a unitary housing and connectible directly between said plurality of LEDs and a power source, and including;
