Abstract:
In various embodiments a light emitting device is disclosed comprising a first and second source for emitting light with a first and a second spectral distribution, respectively, a first and second light guides comprising a first light input surface and a first light exit surface, respectively, the light input surface and the light exit surface of the respective light guide extending at an angle with respect to each other. The first and second light guide configured to convert a part of the received light to light with a third and fourth spectral distribution, respectively, and couple at least a part of the light with the third and fourth spectral distribution out of the first and second light exit surface, respectively. The light have the first and the second spectral distribution having different spectral distributions, and the light having the third and the fourth spectral distribution have different spectral distributions.
