Abstract
Description
Die Erfindung betrifft ein Leuchtmittel mit einer Vielzahl von Leuchtdioden, einem Gehäuse und einem Träger, auf welchem die Leuchtdioden angeordnet sind.The The invention relates to a luminous means having a multiplicity of light-emitting diodes, a housing and a carrier, on which the light-emitting diodes are arranged.
Aus der Gebrauchsmusterschrift zum deutschen Gebrauchsmuster mit dem Aktenzeichen 20 2004 006 871 ist eine Dekorationslichterkette bekannt, die beispielsweise als Unterbodenleuchte für ein Kraftfahrzeug verwendet werden kann. Die Lichterkette weist eine Vielzahl von nebeneinander angeordneten LEDs, als Gehäuse eine einstückige flexible durchlässige hohle Abdeckung, und zwei Leiter für die beiden Elektroden der jeweiligen LEDs auf. Die beiden Enden der Leiter bilden jeweils einen Anschlusskontakt der Lichterkette zur Verbindung mit einer Energieeinspeisung. Die Abdeckung ist an ihren beiden Enden und an ihrer unteren Seite offen ausgebildet, wobei ein Abdichtungsstreifen aus Silikongummi zum dichtenden Schließen der offenen Unterseite der Abdeckung vorgesehen ist.Out of the utility model for the German utility model with the Reference 20 2004 006 871 discloses a decorative light chain used for example as underbody light for a motor vehicle can be. The fairy lights have a variety of side by side arranged LEDs, as a housing a one-piece flexible permeable hollow cover, and two conductors for the two electrodes of the respective LEDs. The two ends of the ladder form respectively a connection contact of the fairy lights for connection to a Energy supply. The cover is at both ends and formed on its lower side open, with a sealing strip made of silicone rubber for sealing closing the open bottom the cover is provided.
Ein Nachteil der aus der Druckschrift bekannten Dekorationslichterkette ist die aufwändige Herstellung. So muss die lichtdurchlässige hohle Abdeckung als Spritzgussteil hergestellt werden. Eine kostengünstige Herstellung als Strangpressteil ist nicht möglich. Ein weiterer Nachteil, der bei der Benutzung der Dekorationslichterkette zum Tragen kommt ist, dass durch die flexible lichtdurchlässige Abdeckung ein Teil des von den Leuchtdioden erzeugten Lichts absorbiert wird und für den Beleuchtungszweck nicht zur Verfügung steht.One Disadvantage of the known from the document decorative light chain is the elaborate production. So must the translucent hollow cover can be produced as an injection molded part. An inexpensive production as extruded part is not possible. Another disadvantage when using the decorative light chain comes to fruition that through the flexible translucent cover a part of the light generated by the light-emitting diodes is absorbed and for the lighting purpose is not available.
Vor dem Hintergrund der bekannten Dekorationslichterkette liegt der Erfindung die Aufgabe zugrunde, ein Leuchtmittel mit einer Vielzahl von Leuchtdioden, Lampen oder dergleichen und einem Gehäuse herzustellen, welches zum einen preisgünstig hergestellt und welches zum anderen eine effektivere Lichtausbeute hat.In front the background of the known decorative light chain is the Invention the task is based, a light source with a variety of light-emitting diodes, lamps or the like and a housing, which for a reasonably priced produced and which on the other hand a more effective light output Has.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Gehäuse ein U-förmiges Profil hat, das der Träger mit den Leuchtdioden auf der einem Steg des Gehäuses abgewandten Seite in dem Gehäuse angeordnet ist, und dass der Schaltungsträger und das Gehäuse mit der Vergussmasse miteinander vergossen sind. Das Gehäuse, welches ein gleichförmiges U-förmiges Profil hat, kann kostengünstig als Strangpressteil hergestellt werden. Damit ist eine kostengünstige Herstellung des Leuchtmittels möglich. Die Leuchtdioden werden zusammen mit dem Träger in dem Gehäuse vergossen. Dabei können die oberen Teile der Gehäuse der Leuchtdioden jedoch aus der Vergussmasse herausragen, so dass keine unnötige Absorption des von den Leuchtdioden erzeugten Lichts durch eine Abdeckung oder dergleichen erfolgt. Dadurch kann die Lichtausbeute des Leuchtmittels im Vergleich zu der aus dem Stand der Technik bekannten Dekorationslichterkette verbessert werden.These Task is inventively characterized solved, that the case a U-shaped Profile has that the carrier arranged with the LEDs on the side facing away from a web of the housing in the housing is, and that the circuit carrier and the case with the potting compound are shed together. The case, which a uniform U-shaped Profile has, can be cost-effective be produced as extruded part. This is a cost-effective production of the bulb possible. The light emitting diodes are encapsulated in the housing together with the carrier. It can the upper parts of the housing However, the LEDs protrude from the potting compound, so that no unnecessary Absorption of the light generated by the LEDs by a Cover or the like is done. As a result, the luminous efficacy of the illuminant compared to that of the prior art known decorative light string can be improved.
Auf dem Träger können vorzugsweise Leiterbahnen angeordnet sein, die geeignet und eingerichtet sind, die Leuchtdioden mit elektrischer Energie zu versorgen. Ebenso ist es theoretisch denkbar, dass anstelle von Leiterbahnen die elektrische Energieversorgung der Leuchtdioden über Drähte erfolgt.On the carrier can Preferably, conductor tracks are arranged, which are suitable and furnished are to provide the light-emitting diodes with electrical energy. As well It is theoretically conceivable that instead of conductor tracks, the electrical Power supply of the LEDs via wires.
Vorzugsweise ist das Leuchtmittel biegsam ausgeführt. D. h., sowohl das Gehäuse, als auch die ausgehärtete Vergussmasse und der Träger sind auch nach der Montage des Leuchtmittels biegsam.Preferably the bulb is flexible. That is, both the housing, as also the cured one Potting compound and the carrier are flexible even after mounting the bulb.
Die Leuchtdioden können bei einem erfindungsgemäßen Leuchtmittel in Erstreckungsrichtung des Gehäuses nebeneinander angeordnet sein. Die Leuchtdioden können dabei in Gruppen, beispielsweise in Gruppen zu drei Leuchtdioden angeordnet sein.The Light-emitting diodes can in a luminous means according to the invention in the extension direction of the housing be arranged side by side. The light-emitting diodes can do this be arranged in groups, for example in groups of three light-emitting diodes.
Vorzugsweise sind die Leuchtdioden einer Gruppe elektrisch in Reihe geschaltet, während die Gruppen selbst wiederum elektrisch parallel zueinander geschaltet sind.Preferably are the light-emitting diodes of a group electrically connected in series, while the groups themselves are in turn electrically connected in parallel are.
Als Leuchtdioden kommen insbesondere RGB-Leuchtdioden in Frage, mit denen Licht verschiedener Farben erzeugt werden kann.When LEDs are in particular RGB LEDs in question, with which light of different colors can be produced.
Das Leuchtmittel kann nach Art einer Leiste ausgebildet sein. Die Breite der Leiste kann dabei wenige Zentimeter, die Länge der Leiste mehrere Meter betragen.The Illuminant can be designed in the manner of a bar. The width the bar can be a few centimeters, the length of the bar several meters be.
Vorzugsweise ist das Gehäuse aus einem Kunststoff, beispielsweise aus einem synthetischen Kautschuk hergestellt.Preferably is the case from a plastic, for example from a synthetic rubber produced.
Das erfindungsgemäße Leuchtmittel kann mit einem Steuergerät zusammengeschaltet werden, wobei das Steuergerät geeignet und eingerichtet ist, die Leuchtdioden oder die Gruppen der Leuchtdioden anzusteuern.The Lamp according to the invention can with a control unit be interconnected, the control unit suitable and furnished is to control the light-emitting diodes or the groups of light-emitting diodes.
Ein Ausführungsbeispiel für ein erfindungsgemäßes Leuchtmittel ist anhand der Zeichnung näher beschrieben. Es zeigt:One embodiment for a Illuminant according to the invention is closer to the drawing described. It shows:

Ebenso ist eine Verwendung zur Beleuchtung von Aquarien, Gartenteichen oder dergleichen denkbar.The Lamp according to the invention can over a per se known control means are controlled. The light source can be used for example as underbody lighting for motor vehicles. Likewise, a use for lighting aquariums, garden ponds or the like conceivable.
