LSG-1700 goniophotometer is an automatic goniophotometric instrument for luminous intensity distribution measurement with facility for rotating the light source. It is for industrial laboratory photometric data measurement of luminaires such as LED luminaires, HID luminaires, fluorescent lamps and so on. Goniophotometer LSG 1700 IES file testing Goniophotometer Specification: • Meets the requ...
In recent years, semiconductor lighting technology has developed rapidly, and subsequently semiconductor lighting lamps have also been greatly developed. This requires corresponding testing theory, testing technology, testing equipment, and testing standards to test and evaluate emerging new products. Vertical Goniophotometer is the core testing equipment of lighting fixtures. It is usually divide...
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...
Goniophotometer is the main measurement equipment for the light distribution performance test of lamps and luminous. It can be used to measure the spatial light intensity distribution of lamps or light sources, total luminous flux and lamp efficiency and other parameters. The composition of the Goniophotometer system includes: precision turntable and control system, spectrum analysis system, stand...
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...
LISUN engineer went to Egypt in December 2018 to provide on-site installation & training services for customers there. During the period, we held a lighting testing technology salon in Glorious Hotel (Cairo, Egypt). LISUN senior engineer Mr. Jacky Jiang shared the following topic there: 1. How to get improve the lumen test accuracy in integrating sphere 2. How to update your LED driver design...
LISUN engineer went to Iran in December 2018 to provide on-site installation & training services for customers there. And held Lighting Testing Technology Salon on 25th afternoon and 26th afternoon. LISUN senior engineer Mr. Jacky Jiang shared the following topic there: 1. How to get improve the lumen test accuracy in integrating sphere 2. How to update your LED driver design to meet the EMC...

In optical testing, the measurement of luminous flux and color temperature are essential. There are two test equipment for the measurement: Integrating Sphere Testing System and Goniophotometer. Here we give you a brief introduction to the difference of goniophotometer vs integrating sphere: 1. Integrating Sphere & Spectroradiometer Test System The Integrating Sphere Test System make me...
LED package is mainly to provide a platform for LED chips, so that LED chips have better performance of light, electricity and heat. Good packaging can make LEDs have better luminous efficiency and good heat dissipation environment, and good heat dissipation environment can enhance LEDs. The service life. LED packaging technology is mainly built on five main considerations, namely optical extracti...
According to the requirements of the LM-79 optical testing standards applicable to the widest range in the world, although there are many photometric measurements for light sources and lamps are available, but these standards are dedicated to the measurements for light sources and lamps. Because the form of current SSL products are lamps or luminaires, and LED in the luminaires is not easy to be ...
LED luminaires are this kind of device which can transmit, distribute, and change the light distribution of light source. They are becoming the main products of a new generation of lighting market with its high efficiency, energy saving, safety, long service life, compact, and other technical characteristics. They effectively promote energy-saving environmental protection industry of high-speed d...
