Title:
LIGHT-EMITTING DEVICE, WAVELENGTH CONVERSION UNIT, AND HEADLIGHT OR DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/060519
Kind Code:
A1
Abstract:
Provided is a light-emitting device (1) comprising: a light-emitting element (20); a plate-shaped light-transmissive heat dissipation member (11); a wavelength conversion member (12) that takes in, from a light scattering layer (12a) side, light which is emitted from the light-emitting element (20) and passes through the light-transmissive heat dissipation member (11), and that converts the wavelength thereof at a phosphor layer (12b); a plate-shaped lateral heat dissipation member that includes a high heat conduction member (13) in contact via a light reflection member (14) with a side surface of the wavelength conversion member (12) and that is in contact with an upper surface of the light-transmissive heat dissipation member (11); and a package (21) that accommodates the light-emitting element (20) and supports a wavelength conversion unit (100) which includes the light-transmissive heat dissipation member (11), the wavelength conversion member (12), and the lateral heat dissipation member.
