摘要： A discharge lamp lighting circuit is provided with a DC power source circuit, a DC-AC conversion circuit, and start circuits. A primary circuit of a transformer in each start circuit has a capacitor and a switch element. When the voltage across the capacitor exceeds a threshold value, or when the switch element has electrical continuity, a high voltage is supplied separately to the discharge lamps from the primary coil through the secondary coil. A common voltage supply circuit supplies the voltage to the primary circuit of each start circuit from the DC power source circuit or the DC-AC conversion circuit.

摘要： An arrangement for detecting the ignition of a high-pressure gas discharge lamp, in particular for use with a motor vehicle headlamp, comprising a circuit for supplying the high-pressure gas discharge lamp with burning energy, a control circuit and an ignition circuit. The ignition circuit is provided with an auxiliary voltage for the ignition. The control circuit is configured such that it detects the ignition of the high-pressure gas discharge lamp immediately via the behavior or the status of the auxiliary voltage (U.sub.H). The control circuit can be provided with a microcontroller (20). The auxiliary voltage supplied during the ignition is connected to the microcontroller in such a way that the microcontroller detects the ignition without delay. For this, the auxiliary voltage is supplied via a voltage divider (22, 23, 24) with logic potential to the external interrupt input (21) of the microcontroller. The declining edge or the low voltage level developing during the ignition as a result of the collapse of the auxiliary voltage is detected immediately by the if microcontroller and is interpreted as ignition.

摘要： A d.c. voltage source delivers the voltage at its output terminals. This voltage is converted to a higher voltage level by a d.c./d.c. converter. This higher voltage level forms the input voltage to a controlled power-supply circuit. From this, the power-supply circuit forms the supply voltage and supply current for a high-pressure gas-discharge lamp to supply it with burning energy. A control circuit is provided to control the power-supply circuit, and an ignition circuit (9) is provided for the ignition. The power-supply circuit is controlled by the control circuit so that the high-pressure gas-discharge lamp is operated with a defined overload when illumination is started. In this context, the overload is defined so as to prevent flickering or light-saddles. The overload is controlled by the control circuit as a function of the state of the high-pressure gas discharge lamp. In so doing, the control circuit takes into account the temperature of the high-pressure gas-discharge lamp, subdivided according to the temperature of the electrodes and the temperature of the gas of the high-pressure gas-discharge lamp.

摘要： A discharge-lamp lighting device stably lights and controls a discharge lamp suitable for use in a vehicle. In the discharge-lamp lighting device, an inverter for receiving DC power from a DC step-up circuit supplies AC power to the discharge lamp. Further, a start-discharging circuit applies a high voltage for effecting start discharging to the discharge lamp. A lamp current controlling circuit decides the value of a current to be supplied to the discharge lamp, based on both the luminous efficiency of the discharge lamp, which varies depending on a voltage applied to the discharge lamp and a voltage for the discharge lamp, which has been detected by a voltage detector circuit. A step-up controlling circuit controls a voltage output from the DC step-up circuit in such a manner that the decided value of current coincides with the value of a current to be supplied to the discharge lamp, which has been detected by a current detector circuit.

摘要： A ballast control apparatus for an electric discharge lamp comprises a first series circuit including a first winding of an AC supply voltage transformer, a first winding of a ballast transformer, a lamp current sensing resistor and the lamp. A current sensing transformer has a first winding parallel to the resistor. A second winding of the supply voltage transformer, the ballast transformer and the current sensing transformer are connected in a second series circuit. A signal voltage proportional to lamp power is derived by adding together the voltages induced in the three series-connected second windings. A second signal voltage proportional to lamp voltage is derived across the series combination of the second windings of the ballast transformer and the supply voltage transformer. The voltage induced in the second winding of the current sensing transformer is proportional to lamp current. A signal voltage indicative of the condition of the lamp load can be derived across the second winding of the ballast transformer. These three signal voltages are used to control a DC/AC inverter that energizes the lamp via the supply voltage transformer.

摘要： A controller for a gas discharge lamp supplies the lamp with a direct current which has been pulse-width modulated at a high frequency via a smoothing circuit and a polarity inversion circuit. The polarity inversion circuit periodically reverses the polarity of current supplied to the lamp to equalize electrode wear in the lamp. The controller senses the lamp voltage, current, power or other characteristics and maintains at least one operating parameter of the lamp, for example the lamp current, constant. A warm up cycle allows this parameter to be adjusted for fast starting of the lamp.
