Study on the color of light source and energy efficiency for floodlight

摘要

For floodlighting, the luminance and the color of the lighted object depend not only on the power and the color of the light source, but also on the color of the lighted object (the spectral reflectance of the surface), this paper put forward the way to choose the optimum matching light source for the lighted object in nightscop lighting design, by calculating the reflected luminous efficiency, comparing the color difference.
