摘　　要：通过发光二极管(LED)的光电特性实验,测量了LED的伏安曲线、发光强度、光谱分布、峰值波长和视角特征,依据LED的光电特性对实验进行了扩展,验验证了最基本的颜色理论———三基色原理,并运用波分复用原理实现了多路信号的传输.A college physics experiments about V-I characteristic, luminous intensity, spectral distribution, peak wavelength, visual angle characteristic of light emitting diode （LED）were intro- duced. Based on the electro-optical characteristics of LED, two experiment of three primary colors theory and the different transmission transmitted by the wavelength division multiplex （WDM）, were expanded.
