LSG-1800B Goniophotometer system is a update version of LSG-1800. The LSG-1800B have a constant temperature detector, and use luminous intensity standard lamp to calibrate the system. Lisun develop a new software to run LSG-1800B. Measures: Electronic parameters, spatial intensity distribution curve, spatial iso-intensity curve, iso-illuminance distribution curve, luminance limitation curve, luminaire efficiency, glare grade, effective beam angle, upward luminous flux ratio, downward luminous flux ratio, total luminous flux, effective luminous flux, utilization factor. Features: • Reaching many measurement ways such as B-β, A-α and C-γ • Can be drived by both double pillars and single pillar • Special laser cross aim device makes the installation of luminaire • The special rotating electric devices for lighting the tested luminaire • Provided with the precious metal fiber for signal transmission • Measured data match with international standard form (IES) and can be applied for lighting design by other lighting design software such as Dialux • Emergency stop function • RS-232C interface, compatible with all kinds of computers • Meets the requirements of IEC, CIE and LM-79 standards
