Abstract :
A simplified Photo-Electro model of high power LED is proposed in this paper. Theoretical derivation of this model and optical experiments are introduced . The variables of this model are forward voltage U and forward current Id, which can be easily obtained and controlled in LED drivers. The validity of this model is verified through two kinds of typical LED chips and the model is helpful to the LED driver design and the LED strategy study.
