Title:
METHOD FOR MANUFACTURING WAVELENGTH CONVERSION MEMBER AND WAVELENGTH CONVERSION MEMBER GROUP
Document Type and Number:
WIPO Patent Application WO/2018/012273
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a wavelength conversion member with which it is possible to obtain a wavelength conversion member with a desired chromaticity with a high degree of accuracy. The method is for manufacturing a wavelength conversion member 1 containing phosphor particles 3 and is characterized by comprising a step of acquiring correlation between the chromaticity and the thickness of a plate-shaped base material containing phosphor particles, and a step of determining target thickness corresponding to target chromaticity for the wavelength conversion member 1 on the basis of the correlation between the chromaticity and the thickness, and grinding the plate-shaped base material to the target thickness.
