摘要
微显示投影技术已开始向小型化发展,研发出集成机和袖珍机,体积小重量轻,便于携带,这都是LED小型光源促进的结果。LED照明系统重点是光能的充分利用,光束扩展理论(Etendue)是有力的设计工具,本文阐述了光束扩展的基本概念及其计算。
Mini-projector has been developed, based on the features of LED ,such as Intergrated and Pocket modules. The Mini-projectors are getting more attentions because of its mini-demension and portable. Etendue is an important tool for designing the illumination system of projectors. The elementary concept of Etendue and its calculation in LED-based projector are given in this paper.
