OPTICAL WAVELENGTH CONVERSION COMPONENT, LIGHT-EMITTING DEVICE, AND METHOD FOR MANUFACTURING OPTICAL WAVELENGTH CONVERSION COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide an optical wavelength conversion component which can prevent an increase in temperature of an optical wavelength conversion member and can prevent light from leaking between a metal frame and the optical wavelength conversion member, a light-emitting device, and a method for manufacturing the optical wavelength conversion component.;SOLUTION: An optical wavelength conversion member 11 of an optical wavelength conversion component 9 is fixed in contact with a metal frame 13 having high thermal conductivity. The inside of the metal frame 13 has an overlapping part 25 which overlaps with an outer periphery of the optical wavelength conversion member 11. Even when the metal frame 13 and the optical wavelength conversion member 11 have different thermal expansion coefficients, a gap is unlikely to be formed between the metal frame 13 and the optical wavelength conversion member 11. When a light-emitting device 5 irradiates the optical conversion member 11 with light for optical wavelength conversion, the light is unlikely to leak from a gap between the metal frame 13 and the optical wavelength conversion member 11 even when a temperature changes.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
