摘要

摘要: 通过对灯具空间光强测试方法的研究，提出了一种空间光强测试新方法。建立了灯具空间光强自动对中的数据模型，介绍了空间光强自动测试装置的组成和测试原理。借助二维扫描系统和专用测试软件绘制出空间光强的三维图形，从而可快速求出灯具x和y轴的光强分布曲线以及发散角，故而可获得所需的测试信息，并可通过全过程测试得到更加丰富的测试信息及测试报告。最后给出将一投影灯置于离探测器5m处的测试结果，按文中所述测试原理测得的峰值光强为2634.4cd，发散角为15.25°。

Abstract: After investigations on the methods usually used in measuring the spatial light intensity of lamps, a new test method for spatial light intensity is proposed. A data model, which can automatically align the spatial light intensity of a lamp, has been established. The structure and principle of the system for automatically measuring the spatial light intensity are introduced. The threedimensional figures of spatial light intensity were drawn with a 2D scanning system and a dedicated test softwave (Matlab). With the technology we can rapidly derive the lightintensity distribution in x and y axes, and the divergence angle of the lamp. An example of measuring a projection lamp is given in details. The ideal results, among which the peak light intensity is 2634.4 cd and the divergence angle is 15.25°， are acquired in the experiment while a lamp is 5m away from the detector of the system.
