SPR-960 spectrofluorimetric system to measurement the 3D fluorescence spectrum, quantum efficiency, energy efficiency, luminous efficiency, fluorescence chromaticity of LED phosphors. The phosphors can be excited by monochromatic light from 200 nm to 800 nm. With the information of 3D fluorescence spectrum, suitable phosphor materials and LED chip can be chosen to implement the best matching in luminous efficacy and color performance (Tc, Ra) for white LEDs.

To determine junction temperature,thermal resistance under the stable and temporal conditions and luminous flux, radiant flux, spectrum distribution, peak wavelength, WHM, electric parameters of LEDs operating at various of ambient temperature and forward current.
