The light source cooling body comprises a homogeneous body () made of a thermally conductive material. The homogenous body comprises an open space that comprises a wick structure, a condenser () and an evaporator (). Near the evaporator the light source cooling body has an interface area () 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 portionof 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.
