Abstract
The invention provides light generating system () comprising a first light generating device (), a luminescent body (), one or more thermally conductive bodies (), and one or more optical elements (); wherein: (A) the first light generating device () is configured to generate first device light (), wherein the first light generating device () comprises a first light source () selected from the group of a superluminescent diode and a laser; (B) the luminescent body () comprises a luminescent material () configured to convert at least part of the first device light () into luminescent material light (); wherein the luminescent body () comprises a first face (), a second face (), and a bridging face () bridging the first face () and the second face (); wherein the second face () has an second face equivalent circular diameter D2, wherein the bridging face () In has a first height (H1), wherein H1/D2<1, and a perimeter (P); (C) the one or more thermally conductive bodies () comprise: (C1) a first thermally conductive body part (), in thermal contact with at least part of the first face (); and (C2) a second thermally conductive body part (), in thermal contact with one or more of (i) part of the bridging face () and (ii) part of the second face (); (D) the first thermally conductive body part () and the second thermally conductive body part () define a slit-like opening () along at least part of the perimeter (P) of the bridging face (); and (E) the first light generating device () and the one or more optical elements () are configured to provide the first device light () via the slit-like opening () to the luminescent body ().
