LED Tester | Christmas Light Tester - LISUN

This is a new company which mainly manufactures lighting fixtures. When we arrived in Russia, our engineers went to customer’s company to do installation training for this customer immediately. This customer purchased our LSG-1700B Rotation Luminaire Goniophotometer (Big Size) and LPCE-3 spectrometer integrating sphere system . Their engineers and managers also received our engineers very enthusiastically. Our engineers carefully guide them how to use the two systems. They also gave them a complete and comprehensive training. During the training, the engineers were always talking and laughing. Our engineers said this ampere training trip was very happy.

Please take a look at the photos taken by customers at that time: [caption id="attachment_11040" align="alignnone" width="900"] Picture 1. Group photo of L...

 The difference between Integrating Sphere Test System and Goniophotometer 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 these two test system: 1. Integrating Sphere & Spectroradiometer Test System The Integrating Sphere Test System make measurement using integral method. Firstly, calibrated the system with a standard lighting source and then measure the sample lamp. The test result of luminous flux or color temperature is the relative value of the data of the standard lighting source. The measurement is made through the diffuse reflection spread the light into the optical fiber, and then measure it, the test time is very short, only need several seconds. In the process of diffuse emission, the light will be affected by the self-absorption performance of the lamp housing, s...
