Taiwan Applied Crystal: High Power LD/LED Illuminous Application—Heat Resistant Phosphor

Application of high-end white light illumination: Laser headlights and laser projectors have been a trend in the use of high-end illumination over the past decade. Initially, white light was created by using blu-ray LD and Ce: YAG fluorescent ceramics (headlights) or by casting LD on a phosphor painted color-wheel plate (projector). As the laser power rises, the heat generated by the conversion of electro-optical efficiency increases the temperature and deteriorates the quantum conversion efficiency of the fluorescent material, which is known as thermal quenching, resulting in...
