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.
