Moving Detector Goniophotometer (Mirror Type C)

What is the definition of type C goniophotometer?

LSG-6000 Moving Detector Goniophotometer (Mirror Type C) manufactured by LISUN completely meets LM-79-24, LM-79-19, COMMISSION DELEGATED REGULATION (EU) 2019/2015, CIE-121, CIE S025, SASO 2902, IS16106 and EN13032-1 clause 6.1.1.3 type 4 requirements. LSG-6000 is the latest upgraded product of LSG-5000 and LSG-3000 in compliance with the requirements of LM-79-19 Clause 7.3.1. It is an automatic light distribution intensity 3D curve testing system for measuring light and the darkroom can be designed according to the customer’s existing room size.

How does Mirror Goniophotometer work?

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.

Specification Highlights

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°.
Photometer detector accuracy: Constant temperature photo detector DIN5032-6/CIE pub1. No. 69 Class L with f1′ < 1.5%.
LISUN goniophotometer software can export CIE, IES, LDT and other format files for use in DiaLux and other illumination design software.
Connect the goniophotometer to PC via USB cable. English software supports Win7, Win8, Win10 and Win11.
LSG-6000 can work with CCD Spectroradiometer for spatial CCT distribution and other spectral color parameters as Goniospectroradiometer (LSG-6000CCD).
LSG-6000CCD software and hardware support plant lighting PAR, PPF and PPFD spatial distribution testing and can export IES/LDT files.

Feature

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 luminaires will be kept without moving at all, and the detector will always sense the light directly from the luminaires.
The rotary motor is from Japan MITSUBISHI MOTORS and the angle decode system is from Germany for smooth high-accuracy rotation and stable start-stop behavior.
The working principles are according to IESNA and CIE, and LSG-6000 completely meets LM-79, LM-75, GB, EN and CIE121-1996 standards.
Special collimation device with cross laser line helps install the position of luminaires under test conveniently and accurately.
