Socket capacitance for discharge lamps

Socket capacitance for discharge lamps

A method and a device for igniting two series-connected HID lamps (1A, 1B) are described, the two HID lamps being connected in series to a single ignitor (10). The ignitor generates a high voltage ignition pulse, which is sequentially applied to the two lamps sequentially, due to a capacitive unbala...

Zusammenfassung:A method and a device for igniting two series-connected HID lamps (1A, 1B) are described, the two HID lamps being connected in series to a single ignitor (10). The ignitor generates a high voltage ignition pulse, which is sequentially applied to the two lamps sequentially, due to a capacitive unbalance between the two lamps. In order to ensure such capacitive unbalance, a capacitor (13) may be arranged in parallel with one of the lamps (1B).
