Abstract: Testing platform for photo-biological safety was built in our laboratory in order to evaluate the potential photo-biological safety risk of indoor LED light sources. Several kinds of indoor LED light sources which were extensively used were tested by this system, mainly including the testing of irradiance and radiance. Furthermore, the work analyzed the experimental results according to the requirement of the standard GB /T 20145—2006: photo-biological safety of lamps and lamp system. At last, the hazard class of the light sources was evaluated and determined. The results have a certain reference significance for the research of testing system and testing method for photo-biological safety of the LED products.

Key words: testing system for photo-biological safety, indoor LED light sources, irradiance, radiance
