Title:
METHOD OF MANUFACTURING LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/023424
Kind Code:
A1
Abstract:
A light-emitting device comprises an LED element (3) that radiates light with a prescribed wavelength; and a wavelength conversion unit further comprising phosphors that are excited by light radiated from the LED element (3) and radiate fluorescence with a wavelength different from the excited wavelength. A method of manufacturing the light-emitting device is provided with: a process for jetting out mixed liquid (40), which comprises the phosphors, layer-formed silicate minerals, and translucent ceramic precursors, towards the LED element (3) from a nozzle (32) of a spray apparatus (30) for jetting out the mixed liquid (40), and coating the LED element (3) therewith, while moving the nozzle (32) relative to the LED element (3); and a process for heating the mixed liquid (40) that was jetted out and coated upon the LED element (3), to form the wavelength conversion unit.
