ULTRAVIOLET LIGHT-EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an ultraviolet light-emitting device including an ultraviolet light-emitting element and a light reflector of a resin molding superior in ultraviolet reflection property.SOLUTION: The ultraviolet light-emitting device includes: an ultraviolet light-emitting element; and a light reflector arranged to reflect a beam of ultraviolet light emitted from the ultraviolet light-emitting element. The light reflector is constituted of a resin molding containing an inorganic filler. The band gap of the inorganic filler is 4 eV or more, and the refraction index thereof is 1.7 or more.
