| Abstract: | In order to accurately describe the volt-ampere characteristics of high-power LED(Light Emitting Diode), the classical Shockley equation is combined with the LED physical model to deduce the theory, the Taylor equation is developed and the model is segmented to construct the electrical parameter model of high power LED.The volt-ampere characteristic curve of the high-power LED is verified to be closer to the actual volt-ampere characteristic curve than the classical PN junction model, which is more consistent with the measured curve,and the error is less than 1%. |
