摘要
本文主要研究和讨论了采用LED作为光源的照明系统的二次配光器件设计方法以及经过配光后的照度分布。在过去的五十年中,照明光学技术取得了重大的发展和进步,一些新的技术和应用逐渐出现并被应用到照明行业的各个领域,如背光照明领域、户外照明领域,室内照明领域以及投影显示领域等等,而这些技术的核心问题就是如何获得预先设定形状的照度分布。与成像光学不同,照明光学系统属于非成像光学的范畴。因此,在本文中,对照明领域中基本问题的回答将从非成像光学的角度论述,这些观点包括了一些新的设计思想和设计理念,例如"边缘光线理论"、"光学扩展量守恒"、"最大收集率"等等,试图建立一个完整的应用于LED照明二次光学设计的框架。
This thesis discusses and researches about the design and illuminance distribution of the illumination system of LED sources for lighting.In the past fifty years,illumination optics had made great progress along with new technologies and applications such as backlighting,outdoor lighting,indoor lighting and projection display etc.But the basic issue behind these technologies and applications is how to get a prescribed irradiance.Different from imaging optics,illumination optics belongs to nonimaging optics.Thus in this dissertation,the essential problem of illumination field will be answered from a viewpoint of nonimaging concepts,concluded the rules and given the new orientation to meet the development of lighting design.In the paper,we will talk about the basic rules and principles of nonimaging optics,such as ＂the edge-ray principle＂,＂the concept of ètendue＂,＂maximum concentration＂,and try to establish the framework of LED optical devices design method.
