What are the types of goniophotometer

There are several common goniophotometers for light distribution. The difference between them lies in the geometric shape of the measurement, that is, how to collect photometric data and how to mechanically realize the measurement. The types of Goniophotometers can be basically divided into Type A, Type B and Type C. For a detailed description, please refer to the 1987 edition of CIE 70. The diffe...

The Difference Between The Total Luminous Flux Test Results Of The Integrating Sphere And The Goniophotometer When Testing Bare Light Sources (Small Lamps) And Big Size lamps
12 May, 2020 2189

The Difference Between The Total Luminous Flux Test Results Of The Integrating Sphere And The Goniophotometer When Testing Bare Light Sources (Small Lamps) And Big Size lamps

According to the provisions of IESNA-LM-79-08, both the integrating sphere system and the goniophotometer can test the luminous flux and color parameters of SSL products. In this experiment, an LED bulb and an integrated street lamp were used to measure the luminous flux in the integrating sphere and goniophotometer, respectively. As shown in the figure below, the same bare light source LED bulb w...
