    摘要: The present invention provides a method of monitoring performance of a discharge lamp. The discharge lamp includes electrodes and a discharge vessel filled with gas and equipped with a luminescent layer, wherein the gas is intended to emit a first ultraviolet light in a first spectral range when the gas is excited by an electric field produced by the electrodes, and at least part of the first ultraviolet light is intended to be changed into a second ultraviolet light in a second spectral range of longer wavelength than the first spectral range by the luminescent layer. The method comprises the steps of finding the value of a first intensity of the first ultraviolet light; finding the value of a second intensity of the second ultraviolet light; and determining the conversion efficiency of the luminescent layer for converting the first ultraviolet light into the second ultraviolet light on the basis of the ratio of the value of the second intensity to the value of the first intensity.

    摘要: This invention relates to a dielectric barrier Xe discharge lamp comprising an UV-B phosphor. The lamp consists of a gas-tight, discharge vessel with a gas filling containing Xe or a Xe/Ne mixture and is provided with a luminescent layer, which comprises at least one luminescent material emitting in the UV-B range (280 to 320 nm). The luminescent layer comprises a Gd3+ activated phosphor according to the formulas McPO4:Gd, Lal1—XAl3(BO3)4:Gdx, and La1—xB3O6:Gdx which is eventually sensitised by Bi3+, Pr3+ or Nd3+ The advantages of such an UV-B emitting discharge lamp over fluorescent lamps based on a Hg low-pressure discharge are a high power density, 10 instant light, long lifetime, a spectral power distribution which is only determined by the phosphor blend, and an arbitrary burner design.
