    摘要： The fragile glass envelope of a fluorescent lamp or similar device is enclosed in a tight-fitting sleeve of shrunk lighttransmitting plastic to provide a shatter-proof and explosionproof lamp. Various fluorescent lamp embodiments wherein the shrunk plastic sleeve is also utilized as a filter, a lightpolarizing component, a radiation-converting medium, and as a means for encasing an exterior starting aid or reflector are also disclosed. In another embodiment the enclosure comprises a loosefitting plastic jacket having shrunk ends, or a separate lighttransmitting plastic jacket that is held in place on the lamp by a pair of overlapping shrunk plastic sleeves, so that the jacket serves both as a protective member and as a thermal insulating enclosure that permits the lamp to be used in outdoor lighting applications.

    摘要： 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.

    摘要： The invention relates to a light source for generating light having a spectral emittance in at least a part of the range of 380 nm to 680 nm. The light has a spectral power distribution E(λ) as a function of the wave-length λ over a first range of 600 nm =0.08, A third ratio of the integral power distribution over said third range to that of a range of 380 nm =0.03 or Ps>=0.015 if Pl>=0.75l A respective radiation emission peak in each of the first, second and third wavelength range has a full width half maximum (=FWHM) of at least 12 nm.
