    Abstract: Provide a compact ultraviolet irradiation device in which a degree of an adverse effect on the human body is suppressed. The ultraviolet irradiation device includes:
    a lamp house (2) on at least one surface of which a light extraction surface (10) is formed;
    an excimer lamp (3) accommodated in the lamp house (2) in a position separated from the light extraction surface (10) in a first direction (X), the excimer lamp (3) that emits ultraviolet light (L1), a main emission wavelength of which belongs to a first wavelength band of 190-225 nm;
    a first electrode arranged in contact with an outer surface of an luminous tube of the excimer lamp (3);
    a second electrode arranged in contact with the outer surface of the luminous tube of the excimer lamp (3);
    an optical filter (21) that is arranged on the light extraction surface (10) and substantially transmits the ultraviolet light (L1) in the first wavelength band and does not substantially transmit ultraviolet light (L1) of a wavelength of 240-300 nm; and
    a reflecting surface (31) that is located outside the luminous tube of the excimer lamp (3) and away from the luminous tube in a third direction (Z) orthogonal to the first direction (X) and a second direction (Y) parallel to a tube axis of the excimer lamp (3), the reflecting surface (31) being inclined to the light extraction surface (10) as seen in the second direction and exhibiting reflectivity with respect to the ultraviolet light (L1) in the first wavelength band.

    Abstract: The present application discloses a novel ultraviolet lamp tube, comprising an outer tube 1; an inner tube 2 coaxially installed inside the outer tube; an outer electrode 4 embedded on the outer tube; and an inner electrode 3 installed inside the inner tube; wherein the outer surface of the inner electrode or inner tube is plated with a clutter waves coating 31 or an inner tube coating 21 that can reflect a desired wavelength band; and the outer sidewall of the outer tube is plated with a single-wavelength band coating 11 that can transmit a single-wavelength band. The coating method is used for wave filtering to ensure monochromaticity of the light emitted by the light source and greatly reduce the volume of the ultraviolet lamp tube. At the same time, the ultraviolet lamp can be in a cylindrical shape to effectively increase the beam angle of the ultraviolet lamp and effectively improve the luminous efficiency of the ultraviolet lamp.

    Abstract: To improve startability in a UV irradiation apparatus equipped with excimer lamps. The UV irradiation apparatus includes a plurality of excimer lamps (11,12) each having a light-emitting tube filled with a discharge gas containing a noble gas. The plurality of excimer lamps includes a first excimer lamp (11) filled with the discharge gas at a first enclosed gas pressure and a second excimer lamp (12) filled with the discharge gas at a second enclosed gas pressure lower than the first enclosed gas pressure. The first excimer lamp (11) is placed in a position such that at least part of light (L12) emitted from the second excimer lamp (12) is allowed to enter the first excimer lamp (11).

    Abstract: An excimer lamp 100 includes a dielectric tube 110, an end cap 120, a conductive hollow tube 130, and an electrode grid 140. The dielectric tube has a closed end 112 and an open end 114, and defines a cavity. The end cap sealingly covers the open end. The conductive hollow tube passes through the end cap and into the cavity of the dielectric tube, with a volume defined between an exterior surface of the conductive hollow tube and an interior surface of the dielectric tube. The volume is configured to hold a gas. The electrode grid is disposed on an exterior surface 118 of the dielectric tube.
