    摘要： A light emission diode (LED) assembly, comprising a LED die (10), a phosphor layer (12), and a filter layer (14), wherein said filter layer (14) is developed in such a manner that light rays with a wavelength of about 400 nm to 500 nm, preferably of about 420 nm to 490 nm, emitted from the LED die (10) are at least partially reflected depending on their emission angle to the normal on the filter layer (14). With the inventive LED assembly it is possible to provide a LED assembly which solves the yellow ring problem without a reduction of the efficiency of the LED assembly.

    摘要： An arrangement for emitting mixed light (5) comprising primary and secondary radiation (51, 52, 53) in a mean direction of emission (5), comprising at least one first electroluminescent light-source (21) for emitting first primary radiation (51) having a maximum intensity at a first wavelength, at least one second electroluminescent light-source (22) for emitting second primary radiation (52) having a maximum intensity at a second wavelength greater than the first wavelength, and a light-converting element (3) for absorbing at least one of the primary radiations (52, 53) and re-emitting the secondary radiation (53), which light-converting element (3) is so arranged that the entire proportion of primary radiation (51, 52) in the mixed light passes through the light-converting element (3), and that the light-converting element (3) comprises a ceramic light-converting material whose microstructure is selected to be such that the color point of the mixed light (5) comprising primary and second radiation is substantially independent of the angle of viewing (B).
