[PH1-2] Tuning of Chromaticity Coordinates for Ce:YAG Single Crystals by Laser Excitation
Laser excitation system, Yellow-emitting phosphor, Correlated color temperature
Phosphor-converted light sources excited by a blue laser have attracted attention. There are few phosphor variations for such lasers and thus the color temperature variation of white is limited. Here, laser light sources are evaluated under various excitation conditions. It is found that the color temperature can be controlled.
