  • Light-emitting device
    Patent number: 11165002
    Abstract: A light-emitting device 1 comprises a base 30, a nitride semiconductor light-emitting element 10 flip-chip mounted on the base 30, and an amorphous fluororesin sealing the nitride semiconductor light-emitting element 10. The light-emitting device 1 comprises a deformation-prevention layer 60 for preventing a shape change of an amorphous fluororesin by heat treatment after shipment of the light-emitting device 1, and the deformation-prevention layer 60 is formed of a layer in which a thermosetting resin or an ultraviolet curing resin is cured, and the cured layer directly covers the surface of the amorphous fluororesin.
    Type: Grant
    Filed: August 30, 2017
    Date of Patent: November 2, 2021
    Assignees: SOKO KAGAU CO., LTD., AGC INC.
    Inventors: Akira Hirano, Yosuke Nagasawa, Masamichi Ippommatsu, Ko Aosaki, Yuki Suehara, Yoshihiko Sakane
  • Ultraviolet light-emitting device, method for manufacturing ultraviolet light-emitting device and method for manufacturing ultraviolet light-emitting module
    Patent number: 11107961
    Abstract: The ultraviolet light-emitting device includes a base, a nitride semiconductor ultraviolet light-emitting element flip-chip mounted on the base, and a lens for sealing a nitride semiconductor ultraviolet light-emitting element to focus or diffuse light emitted from the nitride semiconductor ultraviolet light-emitting device. The lens is composed of an amorphous fluororesin in which a structural unit of a polymer or copolymer has a fluorine-containing aliphatic cyclic structure and a terminal functional group is a perfluoroalkyl group, and a density of the amorphous fluororesin is higher than 2.11 g/cm3.
