摘　　要：分析了大功率白光发光二极管在不同温度下光通量、正向电压、色坐标、波长等参数随温度变化的关系,并对其中部分关系进行了曲线拟合,从而量化了大功率白光发光二极管的光电参数与温度的关系。研究结果表明温度是影响大功率发光二极管光电性能的主要因素。The property of luminous flux, forward voltage,color coordinate and wavelengh of high power white LED have some relations with temperature. This paper reached on these property ,and we also fitted some data, measured the relationship between temperature and photoelectricity property of high power white LED. The results showed that temperature is the main factor to influence the photoelectricity prooerty of high power white LED.
