Integrating Sphere Test System
The Integrating Sphere Test System is used to test the LED relative spectral power distribution Pλ, the chromaticity coordinates (x, y) (u, v), correlated color temperature Tc, color rendering index Ra, standard deviation of color matching SDCM, peak wavelength λp, spectrum half width △λ, dominant wavelength λd, color purity, luminous flux lm, luminous intensity, luminous efficacy, forward voltage, reverse leakage current, and other Light electric performance parameters to ensure products can accord with the international standards.
