Abstract (en)
[origin: US5917287A] The circuit for operating a high-pressure gas discharge lamp (HID) has a device (ZZ+E,uml U+EE ) for ignition-time bridging by switching in a second lamp (GL), the ignition-time bridging device (ZZ+E,uml U+EE ) being driven by a signal (S) indicating the operating state of the high-pressure discharge lamp (HID), and the drive signal (S) being an output signal of a power controller (R) of the circuit.
