A light-emitting module includes: a package substrate that is provided with a recessed portion having an opening at an upper surface thereof; a light-emitting device that is housed in the recessed portion; a window member that is provided on the upper surface such that the window member covers the opening; and a sealing portion that bonds the package substrate and the window member. The window member includes a lens portion facing the light-emitting device and a flange portion that projects from the lens portion and bonds to the sealing portion. The lens portion and the flange portion are formed of the same glass material.

Light-emitting module and method of manufacturing light-emitting module

A sterilization apparatus is provided with: a light source, which has a semiconductor light-emitting element that emits ultraviolet light; a housing, which forms a flow passage through which a fluid subject to sterilization passes; a light receiving unit, which receives a portion of the ultraviolet light emitted from the light source and detects the amount of ultraviolet light that has been received; and a control unit, which controls the output of the semiconductor light-emitting element based on information regarding the amount of ultraviolet light acquired from the light receiving unit. The housing has an incidence portion on which ultraviolet light becomes incident and a reflection portion, which reflects the ultraviolet light at the inner surface thereof. The light receiving unit is provided at a position where the light receiving unit can receive the portion of ultraviolet light that has been transmitted through the reflection portion.

Fluid sterilization apparatus

A sterilization device includes: a treatment chamber with a discharge valve provided on a downstream side of the treatment chamber; a light source that irradiates a fluid stored temporarily in the treatment chamber with ultraviolet light; and a heat exchange chamber connected to an upstream side of the treatment chamber via a gate valve. The heat exchange chamber is thermally connected to the light source. The sterilization device may further include a heat pipe that thermally connects the light source and the heat exchange chamber. The heat pipe may be provided to extend vertically upward from the light source toward the heat exchange chamber.
