A blue-violet enhanced BDJ photodetector and its application in the color measurement of RGB LEDs for solid-state lighting

摘要：

A blue-violet enhanced BDJ photodetector which can simultaneously determine the centroid wavelength and the radiant power of LEDs from 380 to780nm was investigated, and its application in the color measurement and the white balancing of RGB white LEDs was demonstrated. This BDJ photodetector directly gave the chromatic coordinates of a LED that was approximated as a monochromatic stimulus due to its narrow spectrum compared with the CIE colormatching functions. Maximal simulated and experimental errors uv to the target white point of the white balanced RGB LEDs was 0.0154 and 0.0214. The BDJ photodetector also performed to be sensitive to the spectrum variation characterized by CCT, and was preferable as a sensor for monitoring the white point.
