Integrating Spheres - Luminous Flux Measurement For LEDs And Lamps
-
Konica Minolta Sensing Americas, Inc
One of the most important tests in light measurement is the assessment of the total radiant power or luminous flux of light sources using integrating spheres. An integrating sphere’s inside surface is coated with a diffusely reflecting material which guarantees complete integration and homogenization of the emitted radiation. The integrated light is then measured at the detector port.

Light Distribution Photometer Goniophotometer
LCG-1600

Shenzhen Chuangxin Instruments Co., Ltd.
LCG-1600 Goniophotometeric 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 C-γ coordinates. When getting intensity distribution data, computer will calculate other photometric parameters automatically.
