Ansteuerschaltung fuer wenigstens eine lichtemittierende Diode
摘要
<p>A series connection consisting of a diode and one of two transistors of a transistor push-pull circuit is connected in parallel to the feed current path for a light-emitting diode and a capacitor is interconnected between the junction of the push-pull transistors and the junction between the light-emitting diode and an additional diode which is present in the feed current path. When the transistor in the series connection is in a blocking state, the light-emitting diode receives feed current and is thus switched to a light-emitting state. The capacitor causes a current pulse to be superimposed on the feed current during switchover for rapidly driving the light-emitting diode by decreasing the time span required by the light-emitting diode to reach a condition of maximum light emission.</p>
