Abstract: A light source cooling body (100), a light source assembly, a luminaire and a method to manufacture a light source cooling body or a light source assembly are provided. The light source cooling body comprises a homogeneous body (104) made of a thermally conductive material. The homogenous body comprises an open space that comprises a wick structure, a condenser (112) and an evaporator (116). Near the evaporator the light source cooling body has an interface area (102) to thermally couple with a light source and to receive heat from the light source. The condenser is arranged away from the interface area. A portion 114 of the open space is tubular shaped. The open space may hold a cooling liquid partially in the gaseous phase and partially in the liquid phase and the wick structure is configured to transport the cooling material in the liquid phase towards the evaporator.

Abstract: There is provided a light emitting module (1) having at least one light emitting element (3) which is arranged to emit light of a primary wavelength, and a wavelength converting element (5) arranged at a distance from the at least one light emitting element (3). The wavelength converting element (5) is arranged to convert at least part of the light of a primary wavelength into light of a secondary wavelength. Further the module (1) comprises a first optical component (7) having surface structures (11) on a surface facing away from the light emitting element (3). Light rays incident on the first optical component (7) at small angles are reflected and light rays incident on the first optical component (7) at large angles are transmitted and bent towards a normal of the first optical component (7). The invention is advantageous in that it provides a compact and efficient light-directing module.
