The result showed that the luminous flux for LW white LED radiation power output is 298.7 lm and the total photons are 2.7×1018. If under ideal conditions, one electron-hole pair injected yields one blue photon and the quantum efficiency of the phosphor equals one, the numbers of electron-hole pair must equal to the numbers of white photons.

在理想情况下，注入一个电子-孔穴对产生一个蓝光光子，设荧光粉的量子效率为1，因此，注入的电子-孔穴对数亦等于白光光子数，进而计算出白光LED每辐射1 W的光功率所需的电功率为1.51 W，上述白光LED发光光谱对应的白光LED的电-光转换的理论极限流明效率为197.8 lm/W。

The luminous efficiency of cool white LEDs was improved from 38 lm/W to 66 lm/W through the optimum ratio of silicate phosphor. The luminous efficiency of white LEDs with YAG phosphor was 80 lm/W.

经研究最佳化后，以混矽酸盐萤光粉进行封装则光效可从38 lm/W提升至66 lm/W；以混YAG萤光粉进行封装光效可提升到80 lm/W。

The project ducts research on new sealing structure of power-type white light emitting diode to achieve low thermal resistance and emitting efficiency over 80lm/W. It can promote phosphor transfer efficiency and improve sealing technique procedure, introduce automatic production and testing equipment,to increase white light LED emitting efficiency and other performance indexes and further large-scale productivity.
