Abstract
A device for emitting ultraviolet light includes at least one excimer lamp and a housing for the excimer lamp(s). Each excimer lamp has a discharge vessel filled with light-emitting gases, and a pair of first and second electrodes that are placed in contact with the discharge vessel and produce a dielectric barrier discharge inside the discharge vessel. The housing is made of an insulating and heat-resistant resin material. The housing is configured to house the excimer lamp(s), and has a light-emitting window that allows light with a center wavelength in a range from 200 nm to 230 nm emitted from the excimer lamp(s) to exit from the housing.

A device for emitting ultraviolet light, the device comprising:
- at least one excimer lamp, each of the at least one excimer lamp having a discharge vessel filled with light-emitting gases, and a pair of first and second electrodes that are placed in contact with the discharge vessel and produce a dielectric barrier discharge inside the discharge vessel, and
- a housing made from an insulating and heat-resistant resin material, the housing configured to house the at least one excimer lamp, and having a light-emitting window that allows light with a center wavelength in a range from 200 nm to 230 nm emitted from the at least one excimer lamp to exit from the housing
- wherein the housing forms a closed space for housing the at least one excimer lamp.
