摘　　要：针对基于RGB混色技术在小角度、近距离空间内较难实现彩色LED,且有关彩色变焦照明相关文献也较少的问题,设计了一款彩色变焦照明系统。系统主要由LED光源、TIR透镜、微结构透镜组成,可在650mm处实现良好混色照明,变焦范围为4.2°~9.1°(半光强角),且变焦照明过程中,在光强下降为20%的角度内能量利用率达85%以上,半光强角内的能量利用率始终在75%以上,满足设计要求。It is difficult to realize color LED in small angle and close space based on RGB color mixing technology and the related literature on color zoom lighting is also less.One system combined with the zoom and color mixing lighting is proposed with a LED source,TIR lens and microstructure lens.The result shows that a good color mixing effect at650 mm,and the zoom lighting range（half intensity angle）is 4.2°~9.1°.Within the angle which the light intensity decreases to 20%,the energy utilization ratio is more than 85% during the zoom lighting procedure.The energy utilization rate of half-light intensity angle is maintained above 75%,as is expected.
