1800 Rotation Luminaire Goniophotometer Measured Data For Large Size Led Lamp Tester
LCG-1800 can be applied to measure optical parameters for various kinds of LED street lights,luminaries indoor or outdoor.In detail,it can measure spatial intensity distribution curve, cross section spatial intensity distribution curve, isolux distribution curve, luminance limitation curve,area luminous flux,luminaries efficiency, glare class, total luminous flux,effective luminous flux,utilization factor,etc. Test data format meets international standard, can be output in IESNAL format and directly used in international illuminant design software.
Features & Specifications
1) Meets the requirements of China & IEC standards;
2) In order to ensure the luminaire installation, the system can be divided into two structures according to different measurement coordinates:
Double pillars structure (B-β, A-α plane coordinates):
Mainly used to measure FL etc. When installing luminaires, the lighting center of luminare and the rotating center of rotating table shall be at the same position. In B-β coordinates, luminaire axis is superposed with the horizontal axis of rotating table. In A-α coordinates, luminaire axis is vertical with the horizontal axis of rotating table.
Single pillar structure (C-γ plane coordinates and Conic coordinates):
Mainly used to measure downlight and floodlight etc. When installing luminaires, the lighting center of luminare and the rotating center of rotating table should be at the same position, and luminaire axis is superposed with the horizontal axis of rotating table.
Principle
LCG-1800 Goniophotometric System carries out measuring methods of fixed location and rotating luminaires. The measured luminaire is installed on the two-dimension rotating table, using “+” laser to make the luminaire lighting center superposed with the rotating center of rotating table. The mechanical equipment allows turning the tested luminaires around a vertical axis and a horizontal axis. When tested luminaires turn around horizontal axis, the detector which is at the same level with rotating table will measure the intensity of each direction at this surface. When rotating with vertical axis, the detector will measure the intensity at the vertical surface. The vertical and horizontal axis can be rotated continuously at ±180° or 0~360°. According to the measurement requirements, the system can be operated in B-β, A-α, and C-γ coordinates. When getting intensity distribution data, computer will calculate other photometric parameters automatically.
