LM-79 Moving Detector Type C Goniophotometer

What is type C goniophotometer definition?
LSG-6000 Moving Detector Goniophotometer (Mirror Type C) was manufactured by
LISUN completely meets LM-79-19, IES LM-80-08, 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 the LM-79-19 standard
Clause 7.3.1, its an automatic light distribution intensity 3D curve testing
system for measuring light. The measuring distance is from 5m to 30m.

What is the use of goniophotometer?
LSG-6000 gonio photometer manufacturer is LISUN, it can measure all types of
lighting sources, LED, Plant Lighting or HID luminaires such as indoor and
outdoor luminaires, roadway luminaires, street lamps, flood lights and other
kinds of luminaires.

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 luminaire under test rotates around the mirror 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
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.
