Document Type and Number:
Japanese Patent JP5803941
Kind Code:
B2
Abstract:
Disclosed is a method for manufacturing a light emitting device (100) having an LED element (3) and a wavelength conversion part (6) that converts light emitted from the LED element (3) to long-wavelength light, wherein the wavelength conversion part (6) contains a material that elutes a base component in a mixed liquid when dispersed in the liquid. This manufacturing method comprises a step for applying or dripping a first mixed liquid that contains a base component eluted in a dispersion liquid, which is constituted of phosphors and a precipitation preventing agent dispersed in a solvent, onto the LED element (3), heating, and forming a precursor for the wavelength conversion part (6) and a step for applying or dripping a second mixed liquid, in which a translucent ceramic precursor is dispersed in a solvent, onto the precursor for the wavelength conversion part (6), heating, and forming the wavelength conversion part (6).
