Abstract
Thermal management and control techniques for light emitting diode and other incandescent replacement light technologies using a current controller are disclosed.
Claims24
A method of thermal management of an illumination device comprising a light-emitting diode (LED), the method comprising:
- (a) generating a regulated current from a source voltage;
- (b) supplying the regulated current to the LED;
- (c) generating a sense voltage based on (i) the regulated current and (ii) an LED temperature resulting from heat produced by the LED;
- and
- (d) modifying the regulated current supplied to the LED based on the sense voltage, whereby the LED temperature is maintained within a non-destructive range of LED temperatures.
