Abstract
The invention provides a light conversion system () comprising (a) one or more luminescent bodies (), (b) a thermally conductive body (), (c) a waveguide element (), and (d) a light generating device (), wherein: (A) the thermally conductive body () comprises a first reflective face (), and a first slit () in at least part of the first reflective face (), wherein the first slit () comprises a first slit opening (); (B) the waveguide element () comprises a light entrance part () and a light exit part (), wherein at least part of the light exit part () is configured in the first slit (); wherein the waveguide element () is configured to guide at least part of first light () coupled into the waveguide element () via the light entrance part () to the light exit part (); (C) the one or more luminescent bodies () comprise a reflector-directed part () and an optical output part (); wherein the reflector-directed part () is in thermal contact with at least part of the first reflective face () and wherein the reflector-directed part () encloses at least part of the first slit opening (); wherein the one or more luminescent bodies () are configured (a) to receive via at least part of the reflector-directed part () at least part of the first light () escaping from the light exit part () of the waveguide element () and (b) to convert in a light conversion process at least part of the first light () into luminescent material light (), wherein at least part of the luminescent material light () emanates from the optical output part (); and (D) the light generating device () is configured to generate the first light (), wherein the light generating device () is configured upstream of the light entrance part () of the waveguide element (); and wherein the light generating device () comprises a solid state light source.
