Product Description

GPM-2000 Centric Rotating Reflector Goniophotometer Which Meets The Requirement Of  CIE And IESNA Standards  

GPM-2000 goniophotometer is a high intelligent performance testing system. Test distance frm 5m to 30m(adjustable), it can measure all types of lighting sources and luminaires including all kinds of luminaire, such as indoor and outdoor luminaires roodway luminaires, and flood lights with high accuracy, it can achieve the testing program of CIE C-γ,B-β and CIE A-α, the tested results can be used as international lighting design softwares, it meets the requirementsi of CIE and IESNA standards.

Main testing parameters

Luminous intensity data, luminous intensity distribution, zonal luminous flux, luminaires efficiency, luminance distribution, coefficient of utilization, luminance limitation curves, glare, maximum ratio of distance to height, equal illuminance diagrams, curves of luminaires vs lighting area, isocandela curve, efficient luminescence angle etc.


Technical Index:

 1. Tested light can rotate around the reflecting mirror (γ) ± 180 °

 ( or 0-360°) rotation, the measured light itself can be      rotated (C) ± 180 ° (or 0-360 °)

2. Angular precision:0.1 degree,  resolution of driving angle:0.01 degree

3. Photometric test range

    Luminance:0.01lx-10000lx    Intensity:1cd-107cd(detector)

4. Photometric test precision:2%(standard illuminants)

5. Stray light:≤ 0.1%

6. Maximum size lamps and lanterns which can be tested

    Diameter:1400mm           Weight:40Kg

      (2)Ideal temperature in normal test:25±2°C

      (3)Relative humidity:less than 70%(no condensation, air-condition is suggested to install)

9. The tested data must meet the requirements of international and national standards, IESNA file format output can transfer other lighting and lamps and lanterns design software

10.Tested lamp position and the actual use state are the same, lamps working condition is unchanged


Principle:



The goniophotometer rotates the luminaire in the prescribed buring position around the vertical axis and a reflecting mirror rotates around the horizontal axis(Main axis). A auxiliary axis will rotate toward the opposite direction sumultaneously. The combined motion of the luminaire and mirror permit luminous measurement at the direction of any horizontal or vertical angle without tilting the luminare during measurement. The photometer head is located at a fixed position of the limiting photometric distance in front of the reflecting mirror to gather the light in each direction.


 Working status:
