摘要： A light output control device which includes a controllable bidirectional semiconductor which with its mains current path is connected across the two filaments of a luminescent lamp. The firing moment of the semiconductor can be selectively set, so that the average lamp current in each half cycle of the a.c. voltage across the lamp can be controlled. During the intervals in which the semi-conductor is fired, a compensation current is flowing through the lamp filaments, by which proper ignition of the lamp during each half cycle of power source a.c. voltage is ensured.

摘要： A circuit arrangement for controlling an alternating current through a load in response to a control signal applied to its input terminals is provided with an improved organization of a firing circuit arrangement which in its simplest form comprises only two transistors. With a suitable dimensioning of the resistors and capacitors associated with two transistors, highly equivalent voltage waveforms of opposite polarity can be produced during successive half cycles in response to the control signal provided from an asymmetric signal source to fire a semiconductor switch element through its gate control terminal in dependence on that control signal.
