LSG-1600 Type C Goniophotometer 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.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:? C-γ test Meets the requirements of CIE, IEC, IES & GB standards? 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 computersSpecifications:? Photometric accuracy: class 1 (1%)? Test range of illuminance: 0.001Lx to 100,000Lx? Angle accuracy: 0.01 degree?
