The effective reflection luminance of different color temperature (CT) blackbody radiation light sources on warm- toned and cold- toned samples and different dominant wavelength (DW) Gaussian light sources on samples with destined DW are studied. How different CT and DW of light sources work on reflection luminance are obtained. Results show that matched CT of light source and object lead to higher effective reflection luminance, and matched DW of light source and object also lead to higher effective reflection luminance. In multi- chips light emitting diode (LED) spectrum synthesis, matched DW can achieve relatively higher effective refiection luminance and is the key importance of improving effective efficiency, and color appearance of light source should also be taken in consideration. RGB chip LEDs with high purity single chip are more likely to reach high luminivity reflectivity for a designated object. Because of white chip has a low purity, WRB chip LEDs are more stable in luminance reflectivity for all kinds of objects.
