标准简介

This document establishes the ways of expressing the luminance distribution of light sources and luminaires with a planar emitting surface, and describes the measurement conditions, measuring equipment and measurement methods for the luminance distribution. This document is applicable to the measurement, under laboratory or field conditions, of the luminance distribution of lamps, luminaires and modules with a planar emitting surface supplied by AC or DC, and of their lighting systems. The luminance distribution measurement of other light sources and luminaires may be carried out with reference to this document. This document is not applicable to planar light sources and luminaires emitting mainly ultraviolet or infrared radiation.
