The invention describes a light converting device (130) comprising: - a light converter (134) for converting laser light (10) to converted light (20) having a longer peak emission wavelength than the laser light (10), - a heatsink (131) comprising a reflective structure (137), and - a clamping structure (132) mechanically coupling the light converter (134) to the heatsink (131), the clamping structure (132) for pressing the light converter (134) on a surface of the heatsink (131) such that thermal conductance between the light converter (134) and the heatsink (131) is increased and at least a part of the converted light (20) is reflected by means of the reflective structure (137) when illuminated by means of the laser light (10). The invention further describes a laser-based light source (100) comprising such a light converting device (130), and a vehicle headlight comprising such a laser-based light source (100).
