Abstract
A light converting device comprising: a light converter with a light entrance surface and a light emission surface, wherein the light converter is arranged to convert laser light scanned over the light entrance surface to converted light, wherein a peak emission wavelength of the converted light is in a longer wavelength range than a laser peak emission wavelength of the laser light, a confinement structure enclosing the light converter, wherein the confinement structure is arranged to preserve a geometric shape of the light converter in case of a mechanical failure of the light converter. A laser-based light source comprising such a light converting device and a vehicle headlight comprising such a laser-based light source.
