LSG-1800B High Precision Rotation Luminaire Goniophotometer
LSG-1800B Goniophotometer is high precision automatic goniophotometric instrument for luminous intensity distribution measurements with facility for turning the light source. The LSG-1800B is an update version for LSG-1800, the LSG-1800B use a constant temperature detector, Japanese Motor and Germany precision angle coder 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 on each section (represent by right-angled coordinates or polar coordinates, 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 and electric parameters voltage, current, wattage, power factor and etc. The measured data meets IES standard format and can be applied for lighting design by lighting design software. The measurement system fully satisfies the requirement of lighting design work. LSG-1800B Test all of the luminaries which max size is 1.65x1.6m (LxW) Features: • Meets the requirements of CIE, IEC, IES & GB standards • Reaching many measurement ways such as B-βand C-γ • Can be drive 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 • RS-232C interface, compatible with all kinds of computers Technical Specifications: • Photometric measurement range: illuminance0.01lx~99999lx. light intensity 1.0cd～107cd(comply with the latest test distance 2m, the farthest distance test 30m) • Photometric measurement accuracy: 1% • Photometric linearity: 0.2% • Constant temperature photometric detector to choose Class A: f1<3% (Option Class L: f1<1.5%) stray light: less than 0.1% • Angle precision: 0.1degree • Transmission Angle resolution: γ angle is 0.01 degree C angle is 0.01 degree • Files can be export following format:
