More Information
Summary:Light converting device (130) comprising: - a substrate (131) functioning as a heatsink, - a light converter (134) adapted to convert laser light (10) to converted light (20) having a longer wavelength than the laser light (10), wherein the light converter (134) comprises a light entrance surface, a bonding surface opposite to the light entrance surface and at least one side surface, wherein the bonding surface is mechanically and thermally coupled to the substrate (131), - a reflective structure (137) attached to or part of the substrate (131) and comprising at least one reflective metal surface arranged to reflect laser light (10) and converted light (20), wherein the reflective structure (137) is arranged on the side of the substrate (131) facing the light converter (134), and - a translucent ceramic protection layer (138), arranged between the reflective structure (137) and the light converter (134), and having a thickness of less than 50 m icrometres.
