  • Operating circuit for a dielectrically impeded discharge lamp having an overvoltage protection circuit
    Publication number: 20050088116
    Abstract: The invention relates to a method and a circuit for starting or operating discharge lamps which are designed for dielectrically impeded discharges. In this case, it is established in advance, with the aid of an overvoltage protection circuit and test power pulses, whether the discharge lamp is connected.

  • Electronic ballast for a lamp to be operated using iterative voltage pulses
    Publication number: 20050035719
    Abstract: The invention relates to a ballast and its operating method for a dielectrically impeded discharge lamp. The ballast contains a transformer having a third winding which can be short-circuited via a switch. By this means, the injection of the voltage pulse into the lamp circuit may be controlled by an external trigger signal.

  • Dielectric barrier discharge lamp and method and circuit for igniting and operating said lamp
    Publication number: 20040183455
    Abstract: An elongated electrode of a dielectric barrier discharge lamp is divided into two component electrodes (A, A′) by a gap (L). The two component electrodes (A, A′) are driven in an ignition phase in such a way that an auxiliary discharge that facilitates the ignition of the main discharge (E) in the region of the electrode gap (L), in particular when the lamp is in the dark. In normal operation, the component electrodes (A, A′) are driven in such a way that they contribute to the generation of the main discharge (E).
