目前,发光二极管(Light Emitting Diode,LED)作为一种数字显示元件,已经获得广泛的应用,但是在其他领域,诸如照明等还处于起步和探索阶段.本文介绍了基于大功率LED的光照补偿光源的原理、设计过程等.在分析论证的基础上,依据斯派罗准则,通过计算,并且依照实际需要对所得结果进行修正,得到了适合需要的设计.最后,根据实际的需要以及相应的评判标准-五点均匀法则,指出了所设计光源的优越性,同时,根据前后的仿真结果,分析了前后差异的原因.%Now, LED(Light Emitting Dinde)has been widely applied as digital parts of an apparatus for display, while it is on the way of development in other application fields, taking the example of illumination. Principle of light-source for illuminating compensation based on LED of high power and designing process are discussed in this paper. The kind of design meeting requirements is obtained through calculation on the basis of analysis and demonstration, which follows the Spyro Criterion, at the same time, the correction of the result is made considering the actual requirements. Finally, advantages of this design and development trend of illumination are involved on the base of Five-Point-Uniformity-Law. And the reason of differences between theoretical and actual results is obtained by analyzing the simulation results.
