Description
Die Erfindung betrifft eine LED-Röhre mit einem Gehäuse, das eine lichtdurchlässige Abdeckung aufweist, durch die Licht abstrahlbar ist aus dem Gehäuse in eine Umgebung, mit einer Mehrzahl von LEDs, die auf einer der lichtdurchlässigen Abdeckung zugewandten Seite einer Leiterplatte angeordnet sind, und mit einer Gleichrichtereinheit zur Bereitstellung von Gleichstrom für die LEDs.The invention relates to an LED tube having a housing having a translucent cover, can be emitted by the light from the housing in an environment with a plurality of LEDs, which are arranged on one of the translucent cover facing side of a circuit board, and with a rectifier unit for providing DC power to the LEDs.
Aus der
Aufgabe der vorliegenden Erfindung ist es daher, eine LED-Röhre derart weiterzubilden, dass sie mit geringem Aufwand in herkömmliche, für den Betrieb von Leuchtstoffröhren vorgesehene Gehäuseaufnahmen betreibbar sind.Object of the present invention is therefore to develop an LED tube such that they can be operated with little effort in conventional, intended for the operation of fluorescent tubes housing shots.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Schutzanspruchs 1 dadurch gekennzeichnet, dass die Gleichrichtereinheit in einer Anpassungseinrichtung integriert angeordnet ist, die derart ausgebildet ist, dass eine von einem für Leuchtstofflampen vorgesehenen Vorschaltgerät abgegebene Versorgungsspannung auf eine an die LEDs angepasste LED-Versorgungsspannung umgewandelt wird.To achieve this object, the invention in conjunction with the preamble of
Nach der Erfindung ist in einem Gehäuse der LED-Röhre eine Anpassungseinrichtung angeordnet, die derart ausgelegt ist, dass eine von einem für Leuchtstofflampen vorgesehenes Vorschaltgerät bereitgestellte Versorgungsspannung in eine für die in der LED-Röhre angeordneten LEDs angepasste LED-Versorgungsspannung umgewandelt wird. Vorteilhaft ermöglicht die Erfindung, dass mit geringem Aufwand herkömmliche Leuchtstofflampen durch die erfindungsgemäßen LED-Röhren ausgetauscht werden können, ohne dass ein die Leuchtstofflampen aufnehmendes und fest an einer Wand des Gebäudes arretiertes Gehäuse zusätzlich ausgewechselt werden müsste. Sogar das an dem Gehäuse der LED-Leuchte angeschlossene Vorschaltgerät kann verbleiben. Es muss lediglich eine elektrische Überbrückung eines an dem Gehäuse der LED-Leuchte angebrachten Starters erfolgen.According to the invention, a matching device is arranged in a housing of the LED tube, which is designed such that a supply voltage provided by a ballast provided for fluorescent lamps is converted into an LED supply voltage adapted for the LEDs arranged in the LED tube. Advantageously, the invention allows that conventional fluorescent lamps can be replaced by the LED tubes according to the invention with little effort, without the fluorescent lamps receiving and firmly locked on a wall of the building housing would also be replaced. Even the ballast connected to the housing of the LED lamp can remain. All that is required is electrical bridging of a starter attached to the housing of the LED light.
Nach einer bevorzugten Ausführungsform der Erfindung weist die Anpassungseinrichtung einen Mikrokontroller auf, in dem ein LED-Versorgungsprogramm implementiert ist. Das LED-Versorgungsprogramm steuert eine Gleichrichtereinheit derart, dass die von dem Vorschaltgerät bereitgestellte Versorgungsspannung in eine für den Betrieb der LEDs erforderliche Gleichspannung konvertiert wird. Hierbei wird eine Gleichspannung vorgegebener Höhe bereitgestellt. Vorteilhaft ermöglicht der Mikrokontroller eine Anpassung an unterschiedliche LED-Typen. Das heißt, es kann relativ einfach eine an die LEDs angepasste Versorgungsspannung erzeugt werden.According to a preferred embodiment of the invention, the adaptation device has a microcontroller in which an LED supply program is implemented. The LED supply program controls a rectifier unit such that the supply voltage provided by the ballast is converted into a DC voltage required for the operation of the LEDs. In this case, a DC voltage of predetermined height is provided. Advantageously, the microcontroller allows adaptation to different types of LEDs. This means that it is relatively easy to generate a supply voltage adapted to the LEDs.
Weitere Vorteile ergeben sich aus den weiteren Unteransprüchen.Further advantages emerge from the further subclaims.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert.An embodiment of the invention will be explained in more detail with reference to the drawings.
