Patent ID: 7279716

Claim:
A single-chip light-emitting diode (LED) with three luminescent spectrums of red, blue and green wavelengths, comprising: a base; two conductive pins; a single-chip light-emitting element, disposed on the base and electrically connected to the two conductive pins; a package material, for packaging the single-chip light-emitting element; and red fluorescent powder, added to the package material, with an emission wavelength ranging from 585 nm to 710 nm; wherein the single-chip light-emitting element comprising: a substrate, a N-type cladding layer; a P-type cladding layer; at least one green light-emitting layer, formed between the N-type cladding layer and the P-type cladding layer, with an emission wavelength ranging from 510 nm to 585 nm; and at least one blue light-emitting layer, formed between the N-type cladding layer and the P-type cladding layer, with an emission wavelength ranging from 400 nm to 495 nm.
