Abstract:
The invention relates to a high-pressure mercury vapor lamp suitable for sterilization purposes. The high-pressure mercury vapor lamp according to the invention is remarkable in that germanium and oxygen are added in small quantities to the mercury and/or the mercury halides. The addition of germanium monoxide furthermore surprisingly increases the GAC efficiency (GAC: short for Germicidal Action Curve) of a high-pressure mercury vapor lamp, because germanium monoxide emits a strong molecular band system in the range from 250 to 280 nm. The germicidal action of the high-pressure mercury vapor lamp according to the invention is thus increased with respect to that of conventional highpressure mercury vapor lamps. This is apparent from the fact that the GAC-weighted radiant flux is greater than before in the high-pressure mercury vapor lamp according to the invention.

Abstract:
The invention relates to a tubular discharge lamp (1) with a wall (4) which is transparent to UV-radiation. The tube (2) encloses a discharge space (5) having an internal diameter D. The discharge space (5) comprises a filling of mercury metal vapor in a concentration range of 0.4-2.5 mg/cm . A reduction of both the diameter D from about 22 mm down to about 13.5 mm and the average mercury concentration from about 1.7 mg/cm down to about 0.8 mg/cm leads to an increase in the effective germicidal UV-output of the lamp (1) of about 35%.

Abstract:
It is known that one can alter the spectral output of certain discharge lamps by the application of pulsed waveforms rather than simple sinusoidal ones. This effect has been used in the past to make fluorescent lamps of variable colour output. In the invention short pulses (about 1 mu S) at a frequency of about 5 kHz are applied to a discharge lamp such as the low-pressure mercury/argon lamp in order to shift the ratio of the intensities of two of the mercury lines, in particular the 254 nm and 365 nm lines, of which for sinusoidal application the 254 nm line is predominant, towards the higher wavelength. This greatly increases the efficiency of a lamp using phosphors excited by these UV emissions, because of the reduced Stokes shift.
Abstract:
Die Erfindung betrifft eine Vorrichtung für die Behandlung eines Substrats mit UV-Strahlung, umfassend eine Reaktionskammer zur Aufnahme des zu bestrahlenden Substrats, die einen Einlass zur Einleitung eines Stickstoffstroms in die Reaktionskammer aufweist, und einen von der Reaktionskammer räumlich getrennten Kühlkanal zur Durchleitung eines Kühlfluides, und einen UV-Strahler zur Emission der UV-Strahlung auf das Substrat. Um eine Vorrichtung in kompakter Bauweise anzugeben, die mit maximaler Strahlungsausbeute arbeitet und einen effizienten Einsatz des Inertgases und des Kühlfluids ermöglicht, wird erfindungsgemäß vorgeschlagen, dass der UV-Strahler eine Quecksilberdampfentladungslampe mit mindestens einem Quecksilberdepot in mindestens einem Strahler-Ende umfasst, die eine Entladungszone innerhalb der Reaktionskammer aufweist und deren Strahler-Ende mit dem Quecksilberdepot in den Kühlkanal hineinragt. Die Vorrichtung findet in einem Verfahren zur foto-induzierten Polymerisation von Silikonschichten Verwendung.
Abstract:
A high intensity discharge lamp includes a ceramic envelope that defines an enclosed volume that is filled with a pressurized gas, the envelope having an exterior with axial poles and an equator and, when viewed in longitudinal cross section, plural exterior steps extending in series from the respective axial pole to the equator, each of the steps having a flat surface that is angled to refract light from inside the envelope toward a plane of the equator. The flat surfaces may be planar (plural facets in concentric tiers) or annular and the envelope may have a spherical interior surface. The lamp may have a reflector with an aperture that is aligned with the respective axial pole.
