How to improve the accuracy of LED flux test in Sphere?

Abstract: According to the particularity of LED luminous flux measurement, unique optimization is adopted in the design of the integrating sphere for LED measurement combined with the diffuse materials of high reflectivity, which makes the system stability and accuracy have great improvement. The experimental results show that the system stability and consistency is much higher than other commo...

Surge generator anti-interference measurement is based on the international standard IEC 61000-4-5

Surge generator anti-interference measurement is based on the international standard IEC 61000-4-5. Test objective The entire lightning stroke in the nature (namely the indirect thunder such as the lighting stroke between the clouds, or the lighting stroke happened to the adjacent objects) can induce the surge voltage and current in outdoor aerial. Besides, huge surge voltage and current will als...
