Abstract: Methods and systems for producing a change in a medium. A first method and system (1) place in a vicinity of the medium at least one upconverter including a gas for plasma ignition, with the upconverter being configured, upon exposure to initiation energy, to generate light for emission into the medium, and (2) apply the initiation energy from an energy source including the first wavelength λ1 to the medium, wherein the emitted light directly or indirectly produces the change in the medium. A second method and system (1) place in a vicinity of the medium an agent receptive to microwave radiation or radiofrequency radiation, and (2) apply as an initiation energy the microwave radiation or radiofrequency radiation by which the agent directly or indirectly generates emitted light in the infrared, visible, or ultraviolet range to produce at least one of physical and biological changes in the medium.

Abstract: A system for improving an appearance of light from an excimer lamp includes the excimer lamp configured to output excimer light that includes ultraviolet light having an ultraviolet wavelength and visible light having a first visible wavelength or spectra. The system further includes at least one additional light source configured to be packaged with the excimer lamp and to output additional light having a second visible wavelength or spectra. The system further includes a cover that is at least one of transparent or translucent to the ultraviolet wavelength and having a surface pattern that causes the excimer light to blend with the additional light.

Abstract: An excimer lamp includes a housing portion having a sealed internal space, an internal electrode, and a discharge gas with which the internal space is filled. One end side of the internal electrode is electrically connected to a power supply member provided with a metal foil electrically connected to the internal electrode and is sealed together with the power supply member to one end side of the housing portion via a sealing portion. The other end side of the internal electrode protrudes into the internal space. A protrusion length, being a length of the internal electrode in the internal space and a length from one end of the internal space to the other end of the internal electrode, is equal to or less than a length from the other end of the internal electrode to the other end of the internal space in a direction along the axis.

Abstract: The present invention has as an object the provision of a light irradiation device capable of performing optical cleaning with high stability regardless of the transport speed of a workpiece.The light irradiation device of the present invention emits ultraviolet light to one surface of a band-shaped workpiece transported along a transport path, and includes a lamp house having an opening along a passing plane on a side of the one surface of the workpiece in the transport path, an ultraviolet lamp provided in the lamp house so as to extend in a width direction of the workpiece, gas supplier configured to supply a treatment-space gas into the lamp house, and an exhaust space forming member having an opening along a passing plane on a side of the other surface of the workpiece in the transport path. The treatment-space gas is produced by mixing a gas containing oxygen and/or water with an inert gas serving as a principal component, and a shielding body for forming a gas circulation resistance bottleneck between the shielding body and each edge part of the workpiece is provided in the opening of the lamp house.
