LSG-2000 Goniophotometer with Rotating Mirror is also called the Moving Mirror Goniophotometer. The LSG-2000 is an automatic light distribution intensity 3D curve testing system. The darkroom can be designed according to the customer’s existing room size. It can measure all types of lighting sources, LED or HID luminaires such as indoor and outdoor luminaires, roadway luminaires, street lamps, flood lights and other kinds of luminaires.

Features:
- Der Rotationsmotor ist von MITSUBISHI MOTORS aus Japan und das Winkeldecodiersystem ist aus Deutschland. Sie helfen dem Goniophotometer, sich gleichmäßig und mit hoher Genauigkeit zu drehen. Es ist sehr stabil, wenn Start und Stopp.
• The working principles are according to IESNA and CIE. The LSG-2000 completely meets the LM-80, LM-79, LM-75, GB, EN13032-1 and CIE121-1996 Standards.
• Special collimation device with laser cross line help you installaing the position of luminaires undertest conveniently and accurately.
Specifications:
• The mirror rotates around the luminaire under test with an angle of (γ) ±180° (or 0-360°) and the luminaire rotates around itself with an angle of (C) ±180° (or 0-360°).
- Die Genauigkeit des Winkels: 0,05°, Auflösung des Winkels: 0,001°
• Accuracy of Fotodetektor: Constant temperature Fotodetektor DIN5032-6/CIE pub1. Nr. 69 Klasse L
- Die LISUN-Goniophotometer-Software kann Dateien im CIE-, IES-, LDT- und anderen Formaten exportieren. Diese Formatdateien können über andere Beleuchtungs- und Leuchtendesignsoftware wie DiaLux verwendet werden.
• Connect goniophotometer to PC via USB cable. English version software can run on Win7, Win8, Win10 Win11.
• LSG-2000 can be used together with a USB CCD Spectrometer to test spatial CCT Distribution and other Spectral color parameters. We call this system “Goniospectroradiometer (LSG-2000CCD)”. Please download the brochure for LSG-2000CCD.
