1、编号本科生毕业设计（论文）题目：环形荧光灯管光通量测定(配光曲面法)理学院光信息科学与技术专业学号13020702**学生姓名***指导教师***讲师二〇一一年六月摘要本论文开篇先介绍了光源以及光源的辐射能量、辐射通量、辐射强等各项辐射特性；介绍了照明用光源的光强、光通量、发光效率等参数.接下来对气体放电灯的介绍从结构、工作电路开始，详细论述了电子发射、电极、伏安特性等方面的原理。我们着重介绍了电感镇流器及电感—电容镇流器在气体放电灯稳定工作中的作用.在低压水银荧光灯章节中，图表结合，详细讲述了低压汞蒸气放电的最佳汞气压、惰性气体作用、低压汞

2、灯直径和长度、电流密度选定，并对荧光粉层光学特性作了简要概述.在荧光灯设计要点一章中，主要介绍了灯的尺寸和电参数、荧光粉层的选用、电极的结构等.在最后一部分光通量的测量一章中，先对标准光源、光探测器、光强度测量的原理——配光曲面法作了简单介绍；然后详细阐述了配光曲面法测量光通量的原理，对轴对称光源和非轴对称光源的测量分别作了介绍。在对轴对称光源测量的介绍中分别对等角度法和等立体角法作了阐述.在实验中，我们选用的是PHILIPS的环形荧光灯TL5C32W/865，在暗室环境下，利用配光曲面法对光强，光通量进行了测量.关键词：光源；气体放电灯；荧
