灯具配光曲线及其电子文档标准格式

Photometric Curve of Luminaire and Standard Format of Its Electric File

传统的配光曲线表示法无法满足照明计算机辅助设计技术推广与应用的要求,本文列举了国际上比较流行的CIBSETM-14、EULUMDAT、CIE102、IESNALM-63等配光曲线电子文件格式的标准。以IESNALM-63-1995为例,介绍了如何解读灯具配光曲线的IES文件,及值得注意的几个问题,如IES文件中的垂直角度和水平角度,灯具的光学中心、测试灯具光度数据时遇到的问题等。

The requirement of popularization and application of lighting computer aided design technology can not be satisfied by traditional photometric curve. The article lists the international popular standards of electronic file format for photometric curve such as CIBSE TM-14, EULUMDAT, CIE 102, IESNA LM- 63 etc. Taking IESNA LM-63-1995 as an example, it is introduced how to interpret IES file of photometric curve and its remarkable points, such as the vertical and horizontal angle in IES files, photometric center of luminaries, problems in testing luminosity data of luminaries, etc.
