Abstract

A light-emitting diode (LED) with high color-rendering index includes a substrate being provided on one face with a plurality of recesses; a plurality of first chips being separately disposed in the recesses and adapted to emit blue light; a plurality of fluorescent glues being separately filled in the recesses; at least one second chip being disposed on the substrate at a predetermined position to electrically connect to the first chips, and adapted to emit red light; and a light-transmittable layer provided on the substrate to protectively cover the first chips, the fluorescent glues, and the second chip. The blue light emitted from the first chips and the yellow or green light from the fluorescent glues are mixed first, and the produced light is then further mixed with the red light emitted from the second chip to produce warm white light, which is then projected through the light-transmittable layer.
