Abstract:
In various embodiments, a light emitting device is provided comprising a plurality of first solid state light sources for emitting first light with a first spectral distribution, and a first light guide comprising a first light input surface, a first end surface extending in an angle with respect to each other and at least one first further surface extending parallel to the first light input surface. The first light guide receiving the first light at the first light input surface, and guiding a part of the first light to the first end surface. The light emitting device further comprises one first optical element, for shaping light that is coupled out of the first light guide through a part of the at least one first further surface such as to provide a first shaped light, and at least one second optical element on the first end surface.
