Laser phosphor based pixelated light source

Abstract

The invention provides a light generating device () comprising (i) n laser light sources (), (ii) focusing optics (), and (iii) a luminescent body (), wherein: (A) the n laser light sources () are configured to generate laser light source light (); wherein the focusing optics () are configured to focus the laser light source light () into a focused beam () of laser light source light (); wherein n≥2; (B) the luminescent body () comprises a luminescent material (), wherein the luminescent body () is configured in a light receiving relationship with the n laser light sources (), wherein the luminescent material () is configured to convert at least part of the laser light source light () into luminescent material light (); (C) the n laser light sources () and focusing optics () are configured to provide in an operational mode light spots () of laser light source light () on the luminescent body (); wherein k sets of light spots () each have an individually selected number of m light spots (), wherein two or more of the light spots () within each set have a partial overlap, wherein 2≤m≤n and 1≤k<n; and (D) wherein a first spot area () is defined by 10-100% of the maximum intensity in the light spot (), wherein for at least one of the light spots () within at least one of the k sets applies that in the range of 5-80% of its first spot area () overlaps with at least another first spot area () within the set.
