LSG-1800 Goniophotometric system is an automatic goniophotometric measurement system for measuring photometric parameters of luminaires, such as LED road lighting fixture, room lighting fixture and projecting lighting fixture. The measured data meets IES standard format and can be applied for lighting design by lighting design software. The measurement system fully satisfy the requirement of lighting design work.

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
