Abstract

Intelligent lighting system 100 is configured to operate from an AC source 12. An array of visible light emitting diodes (LEDs) 124 responds to environmental room conditions monitored by a sensor circuit. A microcontroller 146 operates in response to sensor circuit communications to control the state of the visible light array. An internal low noise voltage source VL is derived from the waste heat product from a portion of the LED array. The low noise voltage source is used to power the sensor circuit and the microcontroller.
