DEVICE FOR IGNITION WITH TWO INPUT POLES Russian patent published in 2012 - IPC H05B41/04 

FIELD: electricity.

SUBSTANCE: circuit ignition device is proposed, besides, a lamp for provision of a supply AC voltage (U_n) has a corresponding supply circuit, which comprises at least one throttle installed in series with a gas discharge lamp. Besides, the circuit ignition device comprises an igniting transformer, which at the primary side is connected with a control circuit by sparking, and at the secondary side may be connected to a lamp for ignition pulse transfer; an input source of energy for a sparking control circuit; the first switching device in a sparking control circuit; an electronic control device that controls the first switching device. A circuit ignition device corresponding to the invention differs by the fact that at the supply side it comprises an input lead, which in the supply circuit of the lamp may be connected between a throttle and a lamp, and there is a facility provided to model variation of a phase of a lamp AC supply parameter after lamp ignition, especially to identify transition through zero of the AC supply parameter. The invention also relates to the method for operation of the ignition circuit device.

EFFECT: reduced costs for wiring in regular devices for ignition of gas discharge lamps.
