Abstract
A lighting fixture includes a fixture housing. A circuit board is positioned in the fixture housing. The circuit board includes a driver circuit. A plurality of light emitters are disposed on the circuit board. The light emitters are operatively connected to the driver circuit to produce a light output. A temperature sensor is disposed on the circuit board, the temperature sensor configured to measure a temperature of the circuit board and output a signal. The driver circuit is configured to reduce the light output in response to the signal from the temperature sensor.
