1. A light emitting device comprising:

  • a light source adapted for, in operation, emitting light with a first spectral distribution,a first luminescent light guide comprising a first light input surface and a first light exit surface extending at an angle different from zero to one another,and the first luminescent light guide being adapted for receiving the light with the first spectral distribution at the first light input surface, converting at least a part of the light with the first spectral distribution to light with a second spectral distribution, guiding the light with the second spectral distribution to the first light exit surface and coupling the light with the second spectral distribution out of the first light exit surface, anda first transparent heat sink element arranged adjacent to at least one surface of the first luminescent light guide and in the optical path between the light source and the first luminescent light guide, the at least one surface being different from the light exit surface, wherein the first transparent heat sink element is adapted for redirecting light by means of any one of refraction and diffraction.
