Abstract

A method of varying the color of light emitted by a light-emitting device comprising a light-emitting device chip in a phosphor-coated or a phosphor- embedded enclosure. By coating or embedding phosphor on or in the enclosure of the light-emitting device, the phosphor is excited by the blue light emitted from the light-emitting device chip to emit yellow light. Through mixing both the blue and yellow lights, white light is produced.
