WHITE LIGHT LED WITH MULTIPLE ENCAPSULATION LAYERS

摘要

Light-emitting semiconductor devices with multiple encapsulation layers having more uniform white light when compared to conventional light-emitting devices and methods for producing the same are provided. The uniformity of the emitted white light may be quantified by comparing correlated color temperature (CCT) variations between devices, where embodiments of the present invention have a lower CCT variation when compared to conventional devices over a substantial range of light emission angles.
