LM-79 Moving Detector Goniophotometer (Mirror Type C)

Measurement:
Luminous Intensity Data, Photometric Data, Luminous Intensity Distribution, Zonal Luminous Flux, Luminaries Efficiency, Luminance Distribution(Option), Coefficient Of Utilization, Luminance Limitation Curves Glare, Maximum Ratio of Distance to Height, Equal Illuminance Diagrams, Curves of Luminaires VS Lighting Area, Isocandela Diagrams, Efficient Luminescence Angle, EEI, UGR, etc.

Features:
? The near field detector moves together with the big mirror in a line. The big mirror and the far field detector move synchronously.
? The burning position of the lumainares will be kept without moving at all, and the detector will always sense the light directly from the luminares.
? The rotary motor is from Japan MITSUBISHI MOTORS and the angle decode system is from Germany. They help the goniophotometer rotating smoothly with high accuracy. It is very stable when start and stop.
? The working principles are according to IESNA and CIE. The LSG-6000 completely meet the LM-80, LM-79, LM-75, GB, EN and CIE121-1996 standards.
? Special collimation device with cross laser line help you installing the position of the luminaires under test conveniently and accurately.

Specifications:
? The mirror and detector rotates around the luminaire under test with an angle of (γ) vertical axis ±180° (or 0-360°) and the luminaire rotates around itself with an angle of (C) horizontal axis ±180° (or 0-360° ).
? The accuracy of angle: 0.05°, Resolution of angle: 0.001°
? Accuracy of Goniophotometry detector: Constant temperature photo detector DIN5032-6/CIE pub1. No. 69 Class L
? LISUN goniophotometer software can export CIE, IES, LDT and other format files. These kinds of format files can be used via other illumination and luminaire design software such as DiaLux.
? Connect the goniophotometer to PC via USB cable. English version software can run on Win7, Win8 or Win10, Win11
? LSG-6000 can be used together with a CCD Spectroradiometer to test spatial CCT Distribution and other Spectral color parameters. We call this system “Goniospectroradiometer (LSG-6000CCD)”. LSG-6000CCD Goniospectroradiometer = LSG-6000 Goniophotometer System  +  LPCE-2 Integrating sphere Spectroradiometer System. Please click to download the LSG-6000CCD Brochure
? The LSG-6000CCD software and hardware support the plant lighting PAR, PPF and PPFD spatial distribution test , and it can export IES/LDT files

The following Photo Detectors are optional to test UV light:

Goniophotometer adopts the measuring principle of fixed detector and rotating lamp method. The measuring lamp is installed on a two-dimensional rotating worktable, and the luminous center of the lamp coincides with the rotating center of the rotating worktable through the laser beam of the laser sight.
