LSG-2000: Goniophotometer with Rotating Mirror

LSG-2000 Goniophotometer with Rotating Mirror (Moving MirrorGoniophotometer) completely meet LM-79 Clause 9.3.1. The LSG-2000is an automatic light distribution intensity 3D curve testingsystem for measuring light. The measuring distance isfrom 5m to 30m. It can measure all types of lighting sources, LEDor HID luminaires such as indoor and outdoor luminaires, roadwayluminaires, street lamps, flood lights and other kinds ofluminaires.

Measurement:
Luminous Intensity Data,Luminous Intensity Distribution, Zonal Luminous Flux,Luminaries Efficiency, Luminance Distribution, Coefficient OfUtilization, Luminance Limitation Curves Glare, Maximum Ratio ofDistance to Height, Equal Illuminance Diagrams, Curves ofLuminaires VS Lighting Area, Lsocandela Diagrams, EfficientLuminescence Angle Etc.

Features:
•Many national patents pending on hardware and software.
•CIE Class A & Constant temperature photodetector (Class L detector can be optional).
•High degree of intelligent and test function is complete.
•The rotation motor is from Japan MITSUBISHI MOTORS and  ituses Germanic Angle decode system, it will help smoothly and highaccuracy rotation. It is very stable when start and stop.
•The working principles are according to IESNA and CIE. Thisinstrument is specially recommended byLM-75, LM-79 and CIE121-1996.
•With some optional instruments, it has good expandingfunctions
•The position and working state remain the same as it is underworking.
•Special collimation device with laser cross line, conveniently andaccurately fix the position of the tested luminaries.

Specifications:
•The tested luminaire rotates around the mirror with an angle of(γ)±180°(or 0-360°) and the tested luminaire rotates around itselfwith an angle of (C)±180°(or 0-360°).
•The accuracy of angle: 0.1° Resolution of angle: 0.01°
•Accuracy of photometry: CIE class A (Standard Class) or ClassL.
•The test result can be exported as CIE, IES, LDT and other formatfiles. This kind of format files can be transferred by otherillumination and luminaire design software such as DiaLux.
• RS-232C standard interface can be connected to PC, Englishversion software can run in WinXP or Win7
 

LSG-2000 can be used with a USB CCD Spectrometer to testspatial CCT Distribution and other Spectral color parameters. Wecall this system "Goniospectroradiometer (LSG-2000CCD)".
