There are three rotation axes in GMS-2000 goniophotometer. A precision reflecting mirror rotates around the horizontal axle and the tested luminaire rotates in the prescribed burning position and around the vertical axle, meanwhile, a synchronous axle will rotate toward the opposite direction synchronously. The combined motion of the luminaire and mirror permit light measurement at the direction of any horizontal or vertical angle without tilting the tested luminaire, therefore, the luminous intensity will be more stable. The photometer head located at a fixed position of the required photometric distance in front of the reflecting mirror to detect luminous intensity in each direction.

Patent invented integrating sphere for luminous flux and spectral distribution measurement special of T5/T8 LED tube. LED tube is burn-in on a test pole. While doing test, the test pole is directly pushed into the sphere from a special port of the sphere without operation of opening sphere. The uninterruptible power measurement could be achieved for batching testing. It increases more than 5 times efficiency for tube lamp measurement. The interfaces for typical sphere are reserved.

It is specially designed for accurate measurement of power LED devices, modules and lamps.

The test lamp can be measured at any angle as the working direction(up, down and tilt) in the rotating sphere. The rotating sphere can stop in any position for the measurement requirements of 2π side openings geometry and 4π central geometry. The sphere also can be conveniently and safety controlled to rotate to any position for lamp installation. The measuring equipment is fixed all the time to ensure high accuracy photometery and colorimetery measurement.

Mini Spectral Illuminometer is an advanced measuring instrument that combines spectral analysis and illuminance measurement functions, providing detailed information such as the spectral distribution, illuminance, and chromaticity of the light source.

To determine the spectroradiometric and colorimetric parameters by spectroradiometry method according to CIE NO.63, e.g: spectral power distribution, chromaticity coordinates, correlated color temperature, color rending index, color tolerance, color difference, color purty, dominant wavelength, luminous flux, radiant power, photobiology index, luminous efficiency etc. It is widely used in the quality analysis of light sources and luminaries and etc.
