Abstract:
1. A system for supplying power to an LED load, the system comprising: a LED driver module operable to regulate a flow of a LED current through the LED load as a function of a temperature-dependent feedback signal; a current controller module in electric communication with said LED driver module to communicate the temperature-dependent feedback signal to said LED driver module; and a fault detection module in electrical communication with the current controller module, the fault detection module operable to generate a fault detection signal in response to an output signal received from the current controller module, wherein the current controller module is operable to generate the output signal as a function of the flow of the LED current through the LED load, wherein said current controller module is operable to generate the temperature-dependent feedback signal as a function of an operating temperature of the LED load and the flow of the LED current through the LED load.
