Abstract
A lighting system and method for maintaining constant color output. The lighting system may include a first light-emitting diode (LED) configured to emit a first color, a second LED configured to emit a second color, control circuitry configured to control the operation of the first LED, and a temperature sensor positioned in thermal communication with at least one of the first LED and the second LED and in electrical communication with the control circuitry. The luminous intensity of the second LED may vary with temperature. The control circuitry may be configured to control the luminous intensity of the first LED responsive to a temperature indication from the temperature sensor.
