Abstract

A light fixture includes a light source driver circuit and a light engine. The light engine includes a light source and a temperature sensor configured to sense a temperature of the light source. The driver circuit includes a temperatures sensing circuit operable to connect to the temperature sensor and provide a temperature signal indicative of the temperature of the light source. The driver circuit monitors the temperature signal and shuts down an output current provided to the light source when the temperature is outside of a predetermined operating range. The driver circuit is configured to interface with a thermistor or normally bi-metal switch temperature sensor without alteration.
