Abstract

A system and method of thermal management for an LED are provided. A method provided by the system includes (a) providing a forward drive current to power the LED, the forward drive current having a first LED operating current component; (b) detecting the first LED operating current component; (c) sensing a first thermal operating point of the LED; and (d) generating a temperature signal indicative of the first thermal operating point. The method also includes (e) determining a thermal operating range of the LED; (f) determining that the first thermal operating point of the LED is outside the thermal operating range of the LED; and (g) generating a first control setting configured to cause the LED to be driven at a second operating point, the second thermal operating point within the thermal operating range.
