A1: LED for General, mainly parameters such as luminous flux, the spatial distribution of light beam, color rendering index and color feature parameters. From the point of optical performance, LED optical performance mainly involve the spectrum, the performance requirements of the luminosity and chroma, according to “ Semiconductor light-emitting diode method”, the main emitting peak wavelength, spectral bandwidth, axial luminous intensity, half the intensity of light beam angle, luminous flux, luminous efficiency, chromaticity coordinates,correlated color temperature, color purity and dominant wavelength and color rendering index parameters.
