Method for optimal selecting LED light sources and implementing full spectrum light

摘要

A method for optimal selecting light-emitting diode (LED) light sources for full spectrum lighting is disclosed. The optimal selecting method includes the following steps: gathering a plurality of spectral power distributions corresponding to LED light sources; arranging the spectral power distributions to obtain a matrix A corresponding to the LED light sources; calculating a reconstructed coefficient, which is a least-square approximation of the matrix with respect to a spectral power distribution of a CIE standard illuminant; and selecting a best combination of the LED light sources according to the reconstructed coefficient. An LED light source assembly is also disclosed.
