  • Device for operating discharge lamps by means of a transformer with four windings, and a corresponding method
    Patent number: 7034465
    Abstract: A device for operating a plurality of discharge lamps is to be fashioned cost-effectively. Consequently, two discharge lamps (71, 72) are operated with the aid of one ballast in whose load circuit the heating current for the individual incandescent filaments (711, 712, 721, 722) is transmitted via a heating transformer with three secondary windings (Lhs1, Lhs2, Lhs3). The associated primary winding (Lhp) is located in a coupling-out circuit (30) with the aid of which the required heating energy is coupled out via an inductor (Lres). The heating current can be controlled by a temperature-sensitive thermistor (PTC).

  • Low-pressure discharge lamp
    Patent number: 7030564
    Abstract: A low-pressure discharge lamp is described having a base housing (10), a discharge vessel (2), whose end sections are fixed to an end section of the base housing, and a contact-making system for making electrical contact with the lamp, which is located on the end section of the base housing (10) which is remote from the discharge vessel, a conductive section (5) being provided, which is electrically connected to the contact-making system and is arranged adjacent to the discharge vessel (2) in the base housing (10) in such a way that an electrical short circuit is formed around the discharge vessel (2). This makes it possible to reduce the starting voltage of the lamp. As an alternative, or in addition, to this, the cross section of the web attachments is increased, which also increases the rate of the luminous-flux run-up.
