LED light apparatus with instantly adjustable color intensity
View Patent ↗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 ).
