| 摘 要： | 阐述了光强测试的重要性,分析了2种不同光源(点、面)的测试原理,根据测试原理,推导出3种不同的面光源(圆盘形面光源、长条形面光源、长方形面光源)对于不同的测量距离的误差。提出了测试空间的建议,即在满足一定的误差下,可以容许的最小测试距离,从而为室内测试节省大量空间。

| Abstract: | This paper expounds upon the importance of luminous intensity test,analyzes test principles of two different kinds of photo sources(spot,surface),and with testing theory,it derives measurement errors of three different surface light source(disk-shaped surface,a long strip surface,a rectangular surface) relative to different distances.Finally,this paper puts forward the test space: after meeting some of the errors,it can allow the minimum test distance,thus saving a lot of space for indoor testing. |
