Luminous Intensity Distribution Test System for LED Lamp
1. Introduction
PG-1200A luminous intensity distribution test system is applied to test the total luminous flux, isocandela diagram, isolux diagram, IES file and other photometry data. Equip with dark chamber and light diaphragm, the dark room is needless. The test system is applied to test LED reflection lamp fixture, meet the requirements of LM-79, IEC and CIE121.
