    • Proposed is a gaseous-discharge lamp, in particular for motor-vehicle headlamps, comprising a burner vessel of glass or the like having at least two electrodes, the burner vessel being provided with a lamp base that includes the electrical terminals and that is insertable into a lamp base socket. Arranged in the lamp base is an electronic ballast unit that supplies the lamp with the necessary ignition and maintaining voltage. By accomodating the balast unit in the lamp base, one can achieve a small-volume gaseous-discharge lamp having short high-voltage leads i an integrated type of construction, making it possible to keep the ignition voltage to a minimum.

    • An arrangement for protecting a control device for gas discharge lamps from overtemperature contains a control device and a DC/DC converter. Regulation of the power conveyed to the gas discharge lamp is performed. The output value of the power controller (to be considered the manipulated variable) and the input value of the power controller (to be considered the setpoint) are ascertained by way of the control device. The ratio of these two values (manipulated variable to setpoint) is determined. The value determined for that ratio can be used to limit the output power of the control device. The control device may contains a microcontroller, and the controller is provided as a program in the microcontroller and is implemented as software in order to limit the output power of the control device.

    • A DC-DC converter having a transformer, a reactance coil and a controllable switch for turning a DC supply voltage on and off. The contact gap of a switching transistor is set at a reference potential at a connecting tap between a primary winding and a secondary winding of the reactance coil, which is connected like a transformer with a certain transformation ratio. The anode-cathode segment of a diode and an output capacitor are set at reference potentials in series with the secondary winding of the reactance coil, with the output voltage for a load being applied across the output capacitor. The DC supply voltage is supplied to the primary winding of the reactance coil over an inductance arrangement, and a capacitance arrangement is arranged in parallel with the contact gap of the switching transistor so that a series resonant circuit, which is operative in the turn-on and turn-off phases of the switching transistor, is provided by the inductance arrangement and the capacitance arrangement.
