Patent ID: 11933462

Abstract:
The invention provides a light generating device (1000) comprising (i) n laser light sources (10), (ii) focusing optics (20), and (iii) a luminescent body (200), wherein: (A) the n laser light sources (10) are configured to generate laser light source light (11); wherein the focusing optics (20) are configured to focus the laser light source light (11) into a focused beam (21) of laser light source light (11); wherein n≥2; (B) the luminescent body (200) comprises a luminescent material (210), wherein the luminescent body (200) is configured in a light receiving relationship with the n laser light sources (10), wherein the luminescent material (210) is configured to convert at least part of the laser light source light (11) into luminescent material light (211); (C) the n laser light sources (10) and focusing optics (20) are configured to provide in an operational mode light spots (300) of laser light source light (11) on the luminescent body (200); wherein k sets of light spots (300) each have an individually selected number of m light spots (300), wherein two or more of the light spots (300) within each set have a partial overlap, wherein 2≤m≤n and 1≤k<n; and (D) wherein a first spot area (310) is defined by 10-100% of the maximum intensity in the light spot (300), wherein for at least one of the light spots (300) within at least one of the k sets applies that in the range of 5-80% of its first spot area (310) overlaps with at least another first spot area (310) within the set.
