Abstract
The invention describes a laser lighting module for a vehicle headlight comprising a laser for emitting laser light, a light conversion device, and a holographic optical device for transforming part of the laser light to first transformed laser light and focusing that on the light conversion device for converting the first transformed laser light to converted light. The holographic optical device is transparent to the converted light, and transforms another part of the laser light to second transformed laser light which is mixed with the converted light after the latter has been transmitted through the holographic optical device. The invention further describes a vehicle headlight comprising at least one such laser lighting module.
