Integrating Sphere Development Integrating Sphere is used for flux measurement, which can make test result more reliable. Integrating Sphere can reduce the measurement error caused by the shape of light, divergence angle and responsiveness difference in different location on detector. Let us learn more details about the development of Integrating Sphere manufacture technology. Picture […]
LISUN engineer do installation & training in Mexico in December 2017 In December 2017, LISUN engineer went to Mexico to do installation and training for customer. The customer purchased LSG-1800B High Precision Rotation Luminaire Goniophotometer from LISUN. LSG-1800B Goniophotometer is automatic goniophotometric instrument for luminous intensity distribution measurements with facility for turning the light source. The […]
Advantages and disadvantages for total flux test of Integrating Sphere System and Goniophotometer According to IESNA-LM-79-80, the total luminous flux (lumen) of SSL products shall be measured with an integrating sphere system or a goniophotometer. The method may be chosen depending on what other measurement quantities (color, intensity distribution) need to be measured, the size […]
What are EMC tests? With the widespread use of electrical and electronic equipment, the problem of electromagnetic disturbance has also brought electromagnetic pollution. EMC(Electro Magnetic Compatibility) refers to the ability of a device or system to operate within its electromagnetic environment without incurring unacceptable electromagnetic interference to any device in its environment. […]
Goniophotometer System Standard Operating Procedures Goniophotometer is mainly used to measure the light performance of luminaries and light source, it mainly could measure the light intensity distribution curve, light intensity data, beam angle, total flux, luminaries efficiency, zonal luminaries flux, luminance distribution, coefficient of utilization, luminance limitation curves, maximum efficiency ratio of distance to […]
