针对固态体积式真三维立体显示对高亮度和色温可调的要求,设计了采用大功率、单芯片发光二极管(LED)的投影光源。理论计算了投影光源的亮度,结合液晶光阀对不同波长透过率的影响,对理论设计结果进行了修正。考虑寿命、散热等影响因素,提出了采用大功率红绿蓝LED加白光LED的投影光源方案。针对选取的LED发光特性,采用混合集光方法设计了准直器,并进行了仿真和实际测试。测试结果表明:采用准直器后,LED的发散角从±75°减小为±20°。搭建了真三维显示系统样机,测试其屏前亮度达到149cd/m

,且无闪烁,立体感强,但存在视角较小的问题。实验显示,设计的投影光源满足固态体积式真三维立体显示的要求。
According to the needs of solid-state volumetric true-3D display for high brightness and adjustable color temperatures
a projection light source with high power and single chip Light Emitting Diodes(LEDs) was designed. The brightness of the projection light source was computed theoretically. The results were then corrected according to the spectrum curve of a Liquid Crystal(LC) shutter. With the considerations of life and heat dissipation
the projection light source with high-power RGB LEDs and a white LED was put forward. Based on the optical characteristics of the chosen LEDs
the refraction-and-reflection mixed method was applied to the design of collimating lens. Both simulation and practical test were performed on the projection light source. The experimental results show that the divergence angle of the LED has been reduced from ±75°to ±20° after applying the collimating lens. A 3D display prototype was developed. The practical luminance on the LC shutter close to observers reaches 149 cd/m

. The prototype presents the merits of no perceived flickers and strong 3D feeling
as well as the shortcoming of a smaller viewing angle. The proposed light source satisfies the requirements of solid-state volumetric true-3D display.
