The commercial window lighting project has determined the indirect reflection lighting method that can reflect the inner light transmission color effect of the abstract window through the field research on the commercial block and the feedback of relevant opinions. In order to carry out computer abstract simulation of commercial display windows with different light colors in commercial blocks, certain color stimulus selection principles are necessary. The lighting manufacturer project is investigating and summarizing various types of commercial buildings in commercial blocks, and extracts the light colors of four outdoor commercial display windows that often appear in commercial blocks, which are orange-yellow light sources with a color temperature of about 2000k. The color temperature of the light source is warm yellow of about 3000K, the color temperature of the light source is about 4500K of warm white light source and the color temperature of the light source is about 6000K of white light source.
