中文摘要:为有效去除民用飞机座舱中的挥发性有机化合物(volatile organic compounds,简称VOCs),对一种新型飞机管路式光触媒净化装置中的光学部件进行了设计、仿真与优化。该光学部件是将置于导光板端面的紫外发光二极管(ultraviolet light emitting diode,简称UV LED)点光源转换为导光板面光源,以获得净化装置中均匀的光照。受限于净化装置的构型,导光板需设计为两端入光的窄长型结构,而如何获得均匀的面光源出光性能成为一大难题。为了解决这一难题,对该光学部件进行了合理的光学设计,并予以仿真。进而根据仿真结果对导光板上的网点分布作出优化,并获得了较好的面光源出光性能。
英文摘要:In order to remove the VOCs (volatile organic compounds) in civil aircraft cabin efficiently, the optical component in a new aircraft pipe line photocatalytic decontamination device is designed, simulated and optimized in this paper. In this optical component, the UV LED (ultraviolet light emitting diode) point light sources which located at both ends of the light guide plate are transformed into an area light source for uniform illumination in the decontamination device. Limited by the configuration of the device, the light guide plate must be narrow and long, so it is a problem to have uniform optical performance. To solve this problem, reasonable optical design and simulation are conducted in this paper. In addition, dot distribution on the light guide plate is optimized according to the simulation results for better optical performance.
