The wide-spectrum white-light LED electric light source is characterized in that the chip array layer comprises chip arrays formed by combining chips with different emission wavelengths, each array at least comprises a chip, and the fluorescent powder coating array layer comprises fluorescent powder ...
but the LED is still missing many wavelengths of the white light spectrum. Both the low cost of this technology and the general adequacy of the light color
LED术语和实际应用指南白色LED(whitelight emittingdiodes) 白色LED指将多种不同波长的光叠加输出白色光线的二极管。主要用于 液晶面板的背照灯光源、照明光源、霓虹灯、指示器光源以及汽车前照灯光 源等,应用范围较广。由于耗电量低且寿命长,因此可代替荧光管和白炽灯 成为新一代光源而备受期待。白色LED中,加强红色...

荧光材料之激发特性常以激发光谱(Photoluminescence-excitation spectrum;PLE)来判断,通常也可以用荧光光谱仪(Photoluminescence analyzer)进行量测。由于目前LED之发光光谱之波形半高宽多介于10～30 nm之间,且其发光波峰有可能会受操作因素(如温度、功率之影响)而有所迁移,故荧光材料所具有之激发波段通常越宽广越佳。
