LED路灯全空间快速分布光度计系统

Full-field Goniophotometer System for LED Road Lights

总光通量、空间颜色均匀性、空间光强分布及眩光评价和近场分布特性等均是LED路灯极为重要的指标,包括转镜分布光度计在内的传统测量设备只能部分实现以上参数的测试,不能提供全面的测量和评价,快速、精确、全面测量以上技术指标,遇到了前所未有的挑战。在国家863计划项目的持续支持下,我国在LED全空间光分布测量技术方面取得了举世瞩目的成就,拥有核心自主知识产权的相应设备也已成功开发,并出口国际高端市场,受到国际照明委员会(CIE)等国际组织的高度肯定。本文将作具体介绍。

The total luminous flux,spatial color uniformity,spatial luminous intensity distribution,glare estimation,and near-field photometry distribution and etc.are all important specifications to character LED road lights.However,the traditional measurement can only measure part of the specifications,and it is a challenge to measure all the above specifications comprehensively,quickly and accurately.Under the support of national 863 project,China obtains remarkable achievements in the field of LED full-field photometric measurement,nd the corresponding instruments which owns key patents has been developed successfully and exported to national high-end market,it awards high appraisement by the international organizations e.g.CIE.This paper will introduce the full-field goniophotometer and the measurement of LED road lights.
