摘　　要：介绍了几种实用的灯具分布光度测试系统的原理和结构,并对各种系统的性能作了对比分析。重点介绍了一种大型旋转反光镜式空间光分布测试系统,通过使用一个大型椭圆旋转反光镜将光源的光信号反射到光度计探头[1],增加了探测器与光源之间的距离,从而对测试场所的尺寸要求降低。另外,光源的光线不直接到达探测器的受光面上,也减少了杂散光对测量结果的影响。This articale introduces the principle and structure of some kinds of useful lamps and lanterns distributing luminosity measurement system,and makes a contrastive analysis about each kind of system's performance.Make an emphasis on a great distributing luminosity system with a rotary mirror.This equipment uses a big ellipse rotary mirror in order to reflect the source's light signal to the photometer head,adds the distance between the light and photometer head,therefore debates the request of the measure place.Otherwise makes the light's beam can not incidence into the acceptance area of photometer head directly,reduces the affect of stray light.
