LSG-1800B Lamp LED on-line Goniophotometer for LED Light Measurement Introduction: 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. http://www.lisungroup.com/ wooden case
