Title:
OPTICAL MEMBER AND METHOD FOR MANUFACTURING THE SAME, LIGHT EMITTING DEVICE AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2022031299
Kind Code:
A
Abstract:
To achieve an optical member capable of efficiently extracting light.SOLUTION: A method for manufacturing an optical member having a translucent member and a wavelength conversion member includes the steps of: preparing a translucent member in which a metal film and an optical film having a film thickness larger than a film thickness of the metal film are formed in different regions of an upper surface of a base material; preparing the wavelength conversion member having a metal film formed on a lower surface of the base material; and bonding the metal film of the translucent member and the metal film of the wavelength conversion member via metal adhesive under a state in which an optical film is positioned directly below a wavelength conversion section of the wavelength conversion member.SELECTED DRAWING: Figure 12
