一种应用于博物馆文物展示的LED照明系统

A LED Illuminating System Applied in Museum Exhibition

白色发光二极管的诸多优点使其在照明领域的应用越来越广泛 ,将成为继白炽灯、荧光灯和气体放电灯之后新一代的光源 ,二十一世纪将进入以LED为代表的固体光源照明时代。尤其在博物馆文物展示照明中 ,白色LED光源照明的优势更显见。一般的荧光灯或者金属卤化物灯的紫外辐射会对博物馆文物造成不同程度的老化和损害 ,本文提出了一种应用白色LED环形光源的照明系统 ,使得这种损害大大降低 ,在博物馆文物展示中实现了绿色照明。本文给出了该系统的光学设计和理论模型 ,通过计算机编程得到相应的反射镜面曲线方程参数 ,并在光学软件 (ASAP)中模拟出几何模型 ,进行光线追迹和数据分析 ,理论上证实此系统的可行性。

White LED(light emitting diode) has so many advantages that it is applied in more and more illuminating fields, and will be the new generation of light source following the incandescent source、 fluorescent source、 HID source and so on in the 21th century. Especially in museum exhibition, white LED has obvious advantages. The fluorescent lamp or halogen lamp will do harm to the cultural relics by producing ultraviolet, so a new design with white LED annular sources is presented,In this paper,it reduces much of the harm. the optical design model with ASAP、 the relative theory elements and the data analysis are discussed.
