The simulation result shows the collection efficiency of TIR lens model is 67% when the angle of light is confined within 15°. And the uniformity on observation screen is improved in some degree. The optimal design of TIR lens further provides the development space of LED micro-projection display system.4 On the base of the theory research and the model simulation, four projection display systems which have LCOS as micro-display panel and which combine different optical devise for UHP and LED light source respectively are proposed in this dissertation. And the quality of projection display system is evaluated by thesimulation outcome.

模拟结果表明，优化后的TIR透镜可实现将LED大角度扩展光束中67％的光能压缩到15°范围以内，并使目标屏的照明均匀性得到一定的改善，这为LED光源微投影显示系统设计提供了新的发展空间。4在以上理论研究和模拟分析的基础上，将优化和改造得到的照明光学元件应用到微投影显示的照明系统设计中，分别采用UHP和LED光源，设计了四套单片式LCOS微投影显示系统模型，通过光线追迹模拟结果，对系统性能进行了评价分析和对比。

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. So LW white LED radiation power output has to consume 1.51 W electric powers and the luminous flux efficiency limitation of electrical to optical conversion for the white LED is 197.8lm/W at above condition.

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1W的光功率所需的电功率为1.51W，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197.8lm/W。
