Abstract

In order to meet the requirements of multi-color temperature, high precision and wide spectrum, a large number of LED in different colors are used as internal light source for an integrating sphere. An asymmetric Gaussian function model is established to realize non-uniform spectral peak intervals. The research aims to find the desired spectral distribution of LED and the number in use through specific properties of the target spectrum to improve the obtained original fitting model. Simulation of spectral curve of specific color temperature can be realized through the simulation of standard blackbody spectral curve. The result shows that matching simulation error for small band is within 12%, and matching error verified by relative area method is within 4.63%.
