Light Source Quality Evaluating Method by Using Spectral Resemblance With Respect to the Blackbody Radiation

摘要

The present invention relates to a light source quality evaluating method by using spectral resemblance with respect to the blackbody radiation, which mainly comprises 5 method steps. This method is used for evaluating the quality of light based on physiological perception of human. In evaluating operation, the method firstly transfers a power spectrum of a light source to a luminance spectrum of light source through a luminosity function. Next, the method compares the luminance spectrum of light source with a luminance spectrum of the blackbody radiation thereof. Therefore, an index of spectral resemblance with respect to the black body radiation (SR_BR) would be calculated and then obtained, such that the SR_BR can be used for evaluating the quality of the light source. Moreover, comparing to conventional color rendering index (CRI), SR_BR is a better light source quality evaluating method because of having fairness and consistency.
