High intensity white light source with good uniformity based on a plurality of light sources

Abstract

The invention provides a light generating system () comprising: (i) a first set () comprising n1 first light generating devices (), (ii) a first optical element (), and (iii) a luminescent body (), wherein: —the n1 first light generating devices () are configured to generate first device light (); wherein the n1 first light generating devices () may be selected from the group of lasers and superluminescent diodes; —the first set () comprises k1 first subsets () of each at least one first light generating device () of the n1 first light generating devices (), wherein n1≥3, especially n1≥5, and 2≤k1≤n1; —the luminescent body () is configured to: (i) convert part of the first device light () into luminescent material light (), and (ii) transmit part of the first device light (); —the n1 first light generating devices () and the first optical element () are configured to provide first beams () of first device light () to the luminescent body (), wherein two or more first beams () of two or more first light generating devices () of the k1 first subsets () have different first angles of incidence (α) relative to a normal to the luminescent body (); and—in an operational mode of the light generating system () a first intensity of the first device light () of the k1 first subsets () is dependent upon the first angles of incidence (α).
