  • Dielectric barrier discharge lamp and method and circuit for igniting and operating said lamp
    Patent number: 6982526
    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).

  • Circuit arrangement and operating device for operating lamps
    Publication number: 20050285545
    Abstract: The invention relates to circuit arrangements for operating lamps and to operating devices which contain such circuit arrangements. A first stage of a circuit arrangement according to the invention comprises a SEPIC known from the literature. The SEPIC provides a DC voltage which an inverter converts to a radiofrequency AC voltage for lamp operation. According to the invention, an electronic switch (S1) acts both in the SEPIC and in the inverter. Two diodes (D1, D2), which are connected into the supply line for the electronic switch (S1), prevent the SEPIC and the inverter from influencing one another.

  • Circuit for the operation of light sources
    Publication number: 20050275353
    Abstract: An electronic transformer for halogen incandescent lamps is equipped with a self-commutated half-bridge inverter. The half-bridge inverter contains a start circuit with a start capacitor (C3), which starts commutation of the half-bridge inverter after each mains half-wave by driving a lower half-bridge transistor (T2). The start circuit has to be suppressed while the half-bridge inverter is commutating. This is achieved according to the invention by discharging the start capacitor (C3) whenever an upper half-bridge transistor is turned on (T1). This is done by an amplifier element (V1), which is driven via a high-pass filter (C4) from the half-bridge midpoint (M).

  • Supply unit for identifying and powering a LED unit, and method therefor
    Patent number: 6975214
    Abstract: The invention relates to a supply unit (1) and method for detecting the identity of and for supplying power to LED units (2). The supply unit (1) firstly determines, by means of a detection unit (7), the identity of a connected LED unit (2) by the application of an electrical quantity and reception of a further electrical quantity generated in response thereto by an identification unit (3). By means of a control unit (6), the power supply required for the LED unit (2) can subsequently be determined using the identity determined and said power supply can be output to the LED unit (2) via an output unit (5). In this case, both the detection of the identity and the power supply are effected via the supply terminals (4a, 4b).

  • Tubular dielectric barrier discharge lamp and method for its production
    Publication number: 20050253525
    Abstract: A tubular dielectric barrier discharge lamp having a discharge vessel and at least one inner wall electrode has, at least at one end, a constriction 9, which extends along the entire circumference of the discharge vessel and tapers in the direction opposite to the interior of the discharge vessel. The constriction 9 serves the purpose of sealing this end of the discharge vessel in a gas-tight manner via a closure element 4, which is in the form of an exhaust plate and is inserted at this point. The tapering of the discharge tube for the purpose of forming the constriction 9 prevents or at least markedly reduces any negative effect of the electrode spacing and/or the thickness of the dielectric coating of the electrodes in the region of the discharge space which is immediately adjacent to the constriction 9.
