Abstract

Versorgungssystem mit Wechselspannungsquelle für die LED-Beleuchtung, dadurch gekennzeichnet, dass das Leuchtmittel, zwischen den Leuchtdioden mit Vorwiderständen und dem vorgeschalteten Gleichrichter, zusätzlich parallel angeschlossene Kondensatoren enthält.Supply system with AC voltage source for LED lighting, characterized in that the illuminant, between the light-emitting diodes with series resistors and the upstream rectifier, additionally contains capacitors connected in parallel.

Description

Die Erfindung betrifft ein System zur elektrischen Versorgung der Leuchtmittel, die als Lichtquellen Leuchtdioden – LEDs – enthalten.The invention relates to a system for the electrical supply of the lamps, which contain light emitting diodes as LEDs - LEDs.

Eine der verbreiteten Lösungen basiert darauf, dass die Leuchtdioden mit einer stabilisierten Konstantstromquelle versorgt werden. Die deklarierte Lebensdauer der Leuchtdioden wird somit vollständig erreicht.One of the common solutions is based on the fact that the LEDs are supplied with a stabilized constant current source. The declared life of the LEDs is thus fully achieved.

Bei einer anderen bekannten Lösung wird eine Konstantspannungsquelle benutzt, wobei die in Reihe mit den Leuchtdioden geschalteten Vorwiderstände unverzichtbar sind. Die deklarierte Lebensdauer der Leuchtdioden wird kaum beeinflusst.In another known solution, a constant voltage source is used, wherein the series resistors connected in series with the light-emitting diodes are indispensable. The declared lifetime of the LEDs is hardly affected.

Bei einer weiteren bekannten Lösung werden die Leuchtdioden von einer Wechselspannungsquelle versorgt, wobei zwischen den Leuchtdioden mit Vorwiderständen und der Wechselspannungsquelle sich ein Brückengleichrichter befindet; die Leuchtdioden werden mit pulsierendem Strom versorgt. Der Nachteil dieser Lösung liegt daran, dass die Lebensdauer der Leuchtdioden ungünstig beeinflusst werden kann.In another known solution, the light emitting diodes are powered by an AC voltage source, wherein between the light emitting diodes with series resistors and the AC voltage source is a bridge rectifier; the LEDs are supplied with pulsating current. The disadvantage of this solution is that the life of the LEDs can be adversely affected.

Die vorliegende Erfindung ermöglicht die Benutzung einer Wechselspannungsquelle ohne die negative Beeinflussung der Lebensdauer der Leuchtdioden. Dadurch, dass zwischen dem Gleichrichter und den Leuchtdioden ein oder mehrere Kondensatoren zum Einsatz kommen, werden die Leuchtdioden nicht mit pulsierendem, sondern mit annähernd konstantem Strom versorgt.The present invention allows the use of an AC voltage source without negatively affecting the life of the LEDs. The fact that one or more capacitors are used between the rectifier and the light-emitting diodes, the light-emitting diodes are not supplied with pulsating, but with approximately constant current.
