Abstract

Es wird eine Vorrichtung zum Anzeigen einer Meldung mit einer Leuchtdiode und einer den Betriebsstrom der Leuchtdiode steuernden Steuereinheit vorgeschlagen, bei der die Steuereinheit zur Anhebung der Signalwirkung der Meldung den Betriebsstrom (ILED) der Leuchtdiode (1, 2, 3 oder 4) kurzzeitig wiederholt über das sonstige Niveau des Betriebsstroms (IN) anhebt. Des weiteren werden Schaltungsanordnungen aufgezeigt, mit denen die vorgeschlagene Betriebsweise der Leuchtdiode (1, 2, 3 oder 4) realisiert werden kann.
