A light emitting device (1) is provided comprising a light source (2) adapted for, in operation, emitting light (13) with a first spectral distribution, a first luminescent light guide (4) comprising a first light input surface (41) and a first light exit surface (42) extending at an angle different from zero to one another, and being adapted for receiving the light (13) with the first spectral distribution at the first light input surface (41), converting the light (13) with the first spectral distribution to light (14) with a second spectral distribution, guiding the light (14) with the second spectral distribution to the first light exit surface (42) and coupling the light (14) with the second spectral distribution out of the first light exit surface (42), and a first transparent heat sink element (3) arranged adjacent to at least one surface of the first luminescent light guide (4) and in the optical path between the light source (2) and the first luminescent light guide (4), the at least one surface being different from the light exit surface (42), wherein the first transparent heat sink element (3) is adapted for redirecting light by means of any one of refraction and diffraction. |
