A Mathematical Model for Spectra of Both LEDs and Phosphors
Author(s): 
Pages: 532-537
Year: Issue:  6
Journal: Applied Laser

Keyword:  发光二级管 荧光粉 光谱功率分布;
Abstract: 提出了LED光谱数学模型,并对在不同驱动电流条件下红光、黄光、绿光和蓝光LED的光谱分布进行了实验验证。结果表明此光谱模型拟合的LED光谱分布非常接近实际测量光谱分布,优于其他光谱模型,并表明此光谱模型同样适用于荧光粉。进一步对白光LED光谱分布和显色性进行了仿真模拟,结果也表明提出的新光谱模型优于其他光谱模型。
