ULTRAVIOLET LIGHT EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an ultraviolet light emitting device capable of generating a desired quantity of ultraviolet light at a good reproducibility.

SOLUTION: The ultraviolet light emitting device is equipped with an ultraviolet light emitting diode (LED) chip 1 for emitting ultraviolet light and a package A for containing the ultraviolet LED chip 1. The package A is equipped with a light receiving element 4 for detecting ultraviolet light emitted from the ultraviolet LED chip 1. A package 2 is made of an inorganic material and the ultraviolet LED chip 1 is sealed in a sealing part 5 which is made of glass as a translucent inorganic material in the package 2.
