摘要

New laser based remote phosphor solutions are starting to replace conventional lamp or LED systems particularly where high luminance is needed. For automotive applications the light of blue semiconductor laser diodes is partly converted by a yellow phosphor and scattered. This light modules with a lambertian white luminous intensity distribution, a high luminance of more than 200 Mcd/m~2 and a spot size smaller than 0,5 mm is an optimal point source for car headlamp systems. This hybrid of divergent laser and broadband radiation, developed to function as a conventional light source is actually not completely covered by the existing safety standards neither the IEC 60825-1 Ed.3.0:2014 [1] nor the IEC 62471:2006 [2]. A vertical product safety standard can close this gap and provide automotive specific requirements for robustness tests, information about maintenance, service, labelling and measures to avoid failure modes.
