Abstract:
Provided is a solid state lighting apparatus that includes multiple light emitting diodes (LEDs) including at least a first LED and a second LED. The apparatus includes a thermal sensor that is configured to provide a temperature signal corresponding to an operating condition of the solid state lighting apparatus and a control circuit that is configured to receive the temperature signal and to selectively interrupt electrical current to a portion of the plurality of light emitting diodes responsive to the temperature signal including a value that exceeds a high temperature limit.
