A light emitting device (1) comprising plurality of solid state light sources(21, 22, 23), and a transparent substrate (3) comprising a first light input surface (31) and a first light exit surface (32) extending in an angle different from zero to one another, the transparent substrate (3) being adapted for receiving light (13) emitted by the plurality of light sources (21, 22, 23) at the first light input surface (31), guiding the light (13) to the first light exit surface (32) and coupling the light (13) out of the first light exit surface (32), wherein active layers of the plurality of solid state light sources(21, 22, 23) are provided in direct physical contact with the first light input surface (31) of the transparent substrate (32) and wherein the first light input surface has a larger surface area than the first light exit surface. |
