Abstract: A lighting unit which includes a driver, a light source and a buffer capacitor of an auxiliary circuit (such as an independent active electronic circuit). The charging current allowed to flow to the buffer capacitor is controlled based on sensed currents flowing to the light source thereby to control the charging current of the buffer capacitor. In this way, large inrush currents caused by the use of a large buffer capacitor at the output of the driver can be avoided and the triggering of a fault detection mode within the driver can be prevented. Furthermore this circuit ensures that the driver is operated within the specification limits during start-up.

Abstract: A high frequency driver for a gas discharge lamp is supplied with a DC voltage. The driver converts the input DC voltage to an AC voltage and supplies the AC voltage to a load, which comprises a gas discharge lamp, an inductor connected in series with the lamp and a capacitor connected in parallel to the lamp. The AC voltage has a first high frequency during ignition of the lamp and a second high frequency during normal operation of the lamp after its ignition. The first frequency is higher than the second frequency by a ratio of at least 2.2. By modulating the frequency of the AC voltage the ratio can be increased while still complying with EMI and RFI requirements.

Abstract: An electric circuit for igniting a discharge lamp includes a voltage source, and at least one condenser electrically connected to the voltage source. Further, a series chain is provided, electrically connected in parallel with the condenser, of at least one ignition and at least one inductor. A discharge lamp is electrically connected in parallel with the ignition.
