摘要： 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.

摘要： 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.

摘要： A fluid sterilization device includes a straight pipe that constitutes a flow passage extending in a longitudinal direction, and a light source that emits ultraviolet light in the longitudinal direction toward a fluid flowing in a laminar state within the flow passage. The light source includes a light emitting element for emitting ultraviolet light and emits ultraviolet light so as to provide an intensity distribution on a cross section of the flow passage perpendicular to a longitudinal direction, in which the ultraviolet intensity in an area near the center is higher than the ultraviolet intensity around the area.

摘要： A fluid sterilization apparatus includes: a flow passage for causing a fluid to flow; and a light source that irradiates the fluid flowing in the flow passage with ultraviolet light of a wavelength of 290˜310 nm. The fluid contains a cutting fluid for a cutting work or Japanese sake in the process of manufacturing.

摘要： An irradiation apparatus is provided with: a straight pipe that is formed of polytetrafluoroethylene (PTFE); and a light source that is arranged at an end portion of the straight pipe and that irradiates the inside of the straight pipe with ultraviolet light. The light source has a light emitting device that emits ultraviolet light and an adjustment mechanism that adjusts the direction of the ultraviolet light such that the ultraviolet light from the light emitting device becomes incident on the internal wall surface of the straight pipe at an incident angle of 75 degrees or more.
