Measurement Principle LSG-1900B a high accuracy absolute measurement goniophotometer (C type) with no mirror, in accordance with the goniophotometer configuration from NIST U.S.A. Tests both the absolute spatial luminous intensity distribution directly. LSG-1900B can test luminaries rotating in the prescribed burning position and around the vertical axle and a detector rotates around the horizontal axle, meanwhile, a synchronous axle will rotate toward the opposite direction synchronously. The combined motion of the luminaries and detector permit luminous measurement at the direction of any horizontal...

LSG-1900B Goniophotometer is high precision automatic goniophotometric instrument for luminous intensity distribution measurements with facility for turning the light source. The LSG-1900B use a constant temperature detector, Japanese Motor which keeps high test accuracy. It is for industrial laboratory measurements the photometric data of luminaires. Be utilized to measure photometric parameters of luminaires for LED road lighting fixture, room lighting fixture and projecting lighting fixture, such as spatial intensity distribution curve, spatial iso-intensity curve, intensity distribution curve...

The Dimension of Dark Room for Goniometric Rotating Console and Photometric Light Patch: W3.5m*H2.5m*L4m (Other size please check with LISUN engineer) Operator Room for controlling cabinet, computer and printer Dimension: No less than W2.0m*L3.0m The wall, ceiling and floor should be all coated with dull black paint or be covered by black cloth and black carpet. Air-conditioner should be set in the dark room to control the temperature around lamps to the standard value upon the CIE requirements LISUN engineer dept will submit the Lab Design support documents according to the customer’s lab size...
