Abstract

Employing a LED which emits light via excitation with UV light, particularly the foregoing high-power LED, disclosed are a white LED exhibiting high reliability and longer operating life, and a method of manufacturing the white LED. Also disclosed are a white light emitting diode possessing a phosphor layer which emits light via excitation with UV light, wherein the phosphor layer consists of phosphor, or possesses phosphor and transparent inorganic oxide, and a method of manufacturing the white light emitting diode, possessing the step of making phosphor particles to collide with a light emitting diode at high speed to deposit the phosphor layer, employing an aerosol deposition process.
