Integrating Spheres have a specified sensitivity to beam size and beam divergence. An integrating sphere is an optical instrument for capturing a light beam and measuring the power in the beam under specific conditions. It is also known as the Ulbricht Sphere and consists of a hollow spherical cavity. The inner surface is covered with a diffuse white reflective coating and the entrance and exit p...

LM-79 and LM-80 are energy efficiency standards approved by IESNA for LED product testing. LM-79 test refers to the photoelectric measurement of solid-state lighting products, mainly testing the luminous flux, light intensity, color degree, etc. LM-80 luminous flux maintenance rate (LED) life standard mainly tests the maintenance rate of luminous flux output, that is, the life test of LED light so...
After in-depth study on the three main forms of direct lightning strike, conducted lightning strike and induced lightning strike, people have established the theory of lightning induction and high-voltage counterattack, and defined the transmission law of high-voltage lightning wave on metal wire On this basis, gap series fuse arrester, gapless zinc oxide arrester and transient overvoltage surge s...

There are multiple methods for the evaluation of flammability and fire resistance of the material. They are usually direct flame and indirect flame methods. ”Direct Flame Method” applies a flame to a vertically or horizontally placed specimen under specific orientations. On the other hand, the ”Indirect Flame Method” uses a non-flaming heat source and then applies it to the...
Two types of photometry are used: spectrophotometer and goniophotometer. The optical characteristics detection of LED mainly includes: luminous intensity test, luminous flux test, spectral characteristics test (chromaticity coordinate correlated color temperature, color rendering index, dominant wavelength), spatial light intensity distribution test, and the influence of temperature effect on LED ...
