摘　　要：LED照明应用已经从过去的室外照明逐步迈向室内照明应用,因此除了光通量、空间光度分布等指标外,空间颜色分布也是非常重要的一项指标,美国能源之星标准IES LM79-2008以及中国国家标准GB/T 24824-2009,都对LED空间颜色分布提出了测量要求。现根据测量要求设计一种可对低功率LED光源的空间光度和色度分布同步进行快速测量的小型分布式光色度计,该光色度计具有所需场地小,使用灵活的特点。LED lighting applications have gradually changed from outdoor applications in the past into indoor applications. As a result, in addition to indicators such as luminous flux and spatial distribution of luminosity, spatial color distribution is also a very important indicator. The U. S. Energy Star standard IES LM-79： 2008 and China National Standard GB/T 24824 -2009, have both proposed requirements for the measurement of spatial color distribution for LED. The aim of the study is to develop a small, flexible, low cost measurement device for the fast measurement of the light and color distribution specific for low power LED light. The device is easy to use and requires only a small space.
