GMS-5000Full Space Moving Mirror Goniophotometer
Energy Star Recommended Model
Introduction
GMS-5000 Goniophotometer is a highly intelligent light distribution performance testing system. The luminaire under test remains fixed while the moving mirror rotates around it and the probe rotates synchronously so that light enters the detector at normal incidence. It can measure all types of light sources and luminaires (indoor and outdoor luminaires, street luminaires, flood lamps, etc.) with high accuracy. It supports CIE C-γ, CIE B-β and CIE A-α test methods. Test results can be directly used by international lighting design software such as Dialux. It meets the requirements of CIE and IESNA standards including the U.S. Energy Star IESNA LM-79 standard.
Technology & Features
- Meets the requirements of the U.S. Energy Star IESNA LM-79 standard
- Rotation range: reflecting mirror or moving probe around tested light (γ) ±180° (or 0–360°); measured light itself can be rotated (C) ±180° (or 0–360°)
- Angular precision: 0.1°, resolution of driving angle: 0.01°
- Built-in spatial colourimetric test system
- APP control of rotary table (Android), convenient for engineers to install luminaires and improve work efficiency
- Imported servo motors and high-precision absolute encoders; photometric probe accuracy up to Class L, matching error f1'<1.5%
- Supports international file formats: .ies, .gldf, .ldt, .xml, .spdx, directly importable into Dialux and other lighting design software
Applications
Suitable for spatial photometric distribution and total luminous flux testing of indoor lighting luminaires, floodlights, road lights, plant growth lights, floodlights and other light sources and luminaires.
