Arrangement for emitting mixed light
摘要:
An arrangement for emitting mixed light including a primary and secondary radiation with at least one first electroluminescent light-source for emitting first primary radiation, at least one second electroluminescent light-source for emitting second primary radiation, and a light-converting element for absorbing at least one of the primary radiations and re-emitting the secondary radiation. The light-converting element is arranged so that the entire proportion of primary radiation in the mixed light passes through the light-converting element. The light-converting element is a ceramic light-converting material whose microstructure is selected to be such that the color point of the mixed light of primary and second radiation is substantially independent of the angle of viewing.
