Patent number: 8400059Abstract: Known mercury-vapor discharge lamps for planar irradiation are provided with a lamp bulb made of quartz glass, which encloses a closed discharge space having a non-linear gas-discharge channel. In order to provide a structurally simple lamp, which also guarantees a highest possible homogeneity of the UV irradiation, even for a small distance to the surface to be treated, the lamp bulb is formed as a quartz-glass chamber defined by straight walls and having bottom, top, and side walls and is divided into sub-chambers by several separating webs made of quartz glass and projecting from the bottom wall to the top wall. These sub-chambers include a front-most sub-chamber and a rear-most sub-chamber and form in series interconnection the non-linear gas-discharge channel. The separating webs extend alternately from one side wall up to close to the opposite side wall, while leaving open a gap connecting adjacent sub-chambers in a fluid-communicating manner.Type: GrantFiled: July 13, 2011Date of Patent: March 19, 2013Assignee: Heraeus Noblelight GmbHInventors: Alex Voronov, Burkard Jung, Franz-Josef Schilling

Publication number: 20130020942Abstract: In a known method for operating an amalgam lamp having a nominal power Poptimum, it is provided that a lamp voltage Uoptimum designed for a maximum UVC emission is applied between electrodes or a lamp current Ioptimum designed for a maximum UVC emission flows between electrodes. The discharge space is accessible for an amalgam deposit, which is heatable by a heating element in which a heating current Iheating is conducted through the heating element. Starting from this background, in order to provide an operating mode that ensures a stable operation in the region of the optimum power, it is proposed that a target value of the lamp current Itarget is set that is less than Ioptimum and that the heating current Iheating is turned on or increased when the lamp current falls below a lower limit I1 and is turned off or reduced when it exceeds an upper limit I2 for the lamp current.Type: ApplicationFiled: March 14, 2011Publication date: January 24, 2013Applicant: HERAEUS NOBLELIGHT GMBHInventor: Alex Voronov
