LISUN LSG-6000CCD LM-79 Moving Detector Goniospectroradiometer (Mirror Type C) were in the market for more than 10 years, LISUN engineers service team already summary the most of the After Sales Questions and Answers in the above link. Please read it carefuly, you can solve the most of the problems by yourself if you have some questions while using the instruments. LISUN will be continue to update this pages and more FAQ can be found in this topic link.
Supported Standards
| LM-79-19 | Optical and Electrical Measurements of Solid State Lighting Products |
| EN13032-1 | Light and lighting – Measurement and presentation of photometric data of lamps and luminaires – Part 1: Measurement and file format; German version EN 13032-1:2004+A1:2012 |
| CIE-121 | The Photometry and Goniophotometry of Luminaires |
| CIE S025 | Test Method for LED Lamps, LED Luminaires and LED Modules |
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.
