Description
Die Erfindung betrifft eine Leuchte mit einem Leuchtengehäuse und einer, auf einer Leiterplatte angeordneten elektronischen Schaltung.The invention relates to a lamp with a lamp housing and an electronic circuit arranged on a printed circuit board.
Aus dem Stand der Technik ist eine Leuchte mit einem Leuchtengehäuse und einer elektronischen Schaltung bekannt, bei der die elektronische Schaltung auf einer Leiterplatte angeordnet ist, die in dem Leuchtengehäuse montiert ist. Die Leiterplatte mit der darauf angeordneten Elektronik ist also im Innenraum des Leuchtengehäuses angeordnet und von Letzterem umschlossen. Zur Montage wird die Leiterplatte in dem Leuchtengehäuse befestigt und anschließend Letzteres mit einem Deckel verschlossen.A lamp with a lamp housing and an electronic circuit is known from the prior art, in which the electronic circuit is arranged on a printed circuit board which is mounted in the lamp housing. The circuit board with the electronics arranged on it is thus arranged in the interior of the lamp housing and enclosed by the latter. For assembly, the circuit board is fastened in the luminaire housing and then the latter is closed with a cover.
Insbesondere im Fall von Leiterplatten, auf denen LEDs (LED: Lichtemittierende Diode) zur Lichterzeugung angeordnet sind, muss Sorge dafür getragen werden, dass die während des Betriebs der LEDs von Letzteren erzeugte Wärme effizient abgeführt wird. Eine entsprechende Problematik ergibt sich auch im Fall einer Leiterplatte, auf der elektronische Komponenten zum Versorgen von Lichtquellen angeordnet sind. In beiden Fällen ist durch die Anbindung der Leiterplatte an das Leuchtengehäuse ein thermischer Widerstand gebildet, so dass eine besondere thermische Kopplung zur Abfuhr der Wärme zwischen der betreffenden Leiterplatte und dem Leuchtengehäuse vorgesehen werden muss. Hierzu ist insbesondere ein nicht zu vernachlässigender Material- und Montageaufwand erforderlich.Particularly in the case of printed circuit boards on which LEDs (LED: light-emitting diode) are arranged to generate light, care must be taken to ensure that the heat generated by the LEDs during operation is efficiently dissipated. A corresponding problem also arises in the case of a printed circuit board on which electronic components for supplying light sources are arranged. In both cases, a thermal resistance is formed by the connection of the circuit board to the luminaire housing, so that a special thermal coupling for dissipating the heat must be provided between the relevant circuit board and the luminaire housing. This requires in particular a not insignificant expenditure of material and assembly.

Der Erfindung liegt die Aufgabe zugrunde, eine entsprechende verbesserte Leuchte anzugeben, insbesondere eine Leuchte mit reduziertem Herstellungs- und Montageaufwand.The invention has for its object to provide a corresponding improved lamp, in particular a lamp with reduced manufacturing and assembly costs.
Diese Aufgabe wird gemäß der Erfindung mit dem in dem unabhängigen Anspruch genannten Gegenstand gelöst. Besondere Ausführungsarten der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved according to the invention with the subject matter mentioned in the independent claim. Particular embodiments of the invention are specified in the dependent claims.
Gemäß der Erfindung ist eine Leuchte vorgesehen, die ein Leuchtengehäuse und eine, auf einer Leiterplatte angeordnete elektronische Schaltung aufweist. Die Leiterplatte ist dabei derart gestaltet und angeordnet, dass durch sie ein Außenwandbereich des Leuchtengehäuses gebildet ist.According to the invention, a lamp is provided which has a lamp housing and an electronic circuit arranged on a printed circuit board. The circuit board is designed and arranged in such a way that it forms an outer wall area of the lamp housing.
Hierdurch lässt sich erzielen, dass die Leiterplatte in unmittelbarem Kontakt mit einer Umgebungsluft der Leuchte steht. Auf diese Weise ist eine effiziente und quasi direkte Abfuhr der Wärme ermöglicht, die während eines Betriebs der Leuchte durch die elektronische Schaltung erzeugt wird. Es ist sozusagen eine sehr gute thermische Anbindung an die Umgebung erzielt. Dabei lässt sich ein Montageschritt einsparen, da das Leuchtengehäuse nach der Montage der Leiterplatte nicht mehr gesondert mit einem Deckel oder Ähnlichem geschlossen werden muss.In this way it can be achieved that the circuit board is in direct contact with the ambient air of the lamp. In this way, an efficient and quasi-direct dissipation of the heat that is generated by the electronic circuit during operation of the luminaire is made possible. A very good thermal connection to the surroundings is achieved, so to speak. One assembly step can be saved since the luminaire housing no longer has to be closed separately with a cover or the like after the circuit board has been installed.
Bei der Leiterplatte handelt es sich vorzugsweise um eine Metallkernplatine, insbesondere um eine Metallkernplatine mit einer einseitigen Leiterbahnführung. Die der Leiterbahnführung gegenüberliegende Außenfläche der Leiterplatte kann dementsprechend ohne Leiterbahnen gestaltet sein, so dass sie sich besonders für einen unmittelbaren Kontakt mit der Umgebungsluft eignet.The printed circuit board is preferably a metal core board, in particular a metal core board with a one-sided conductor track guide. The outer surface of the circuit board opposite the conductor track guide can accordingly be designed without conductor tracks, so that it is particularly suitable for direct contact with the ambient air.
Erfindungsgemäß ist die Leiterplatte an dem restlichen Leuchtengehäuse mittels einer Schraubverbindung und/oder Schnappern und/oder einer Verriegelung und/oder eines Einschubs befestigt. Ein Schnapper oder eine sonstige Rastverbindung ermöglicht eine besonders einfache Montage. Dabei sind die Leiterplatte und das restliche Leuchtengehäuse so gestaltet, dass bei wie vorgesehen angeordneter Leiterplatte auf zwei gegenüberliegenden Seiten der Leiterplatte Freiräume gebildet sind, die durch Vergießen geschlossen sind. Durch einen Verguss lässt sich besonders geeignet eine dichte Verbindung zwischen der Leiterplatte und dem restlichen Leuchtengehäuse bilden.According to the invention, the printed circuit board is fastened to the remaining luminaire housing by means of a screw connection and / or snappers and / or a lock and / or an insert. A snap or other locking connection enables particularly simple assembly. The circuit board and the rest of the luminaire housing are designed in such a way that, when the circuit board is arranged as intended, free spaces are formed on two opposite sides of the circuit board and are closed by potting. A potting compound is particularly suitable for forming a tight connection between the circuit board and the rest of the luminaire housing.
Vorzugsweise weist das Leuchtengehäuse eine Schulterfläche auf, die zur Anlage der Leiterplatte ausgebildet ist. Hierdurch lässt sich besonders geeignet eine definierte Positionierung der Leiterplatte gegenüber dem restlichen Leuchtengehäuse bei einfacher Montage erzielen.The luminaire housing preferably has a shoulder surface which is designed to abut the printed circuit board. This makes it particularly suitable to achieve a defined positioning of the circuit board with respect to the rest of the luminaire housing with simple assembly.
Ein besonders dichtes Leuchtengehäuse lässt sich erzielen, wenn zwischen der Leiterplatte und dem restlichen Leuchtengehäuse dichtend ein Dichtelement angeordnet ist.A particularly tight luminaire housing can be achieved if a sealing element is sealingly arranged between the circuit board and the rest of the luminaire housing.
Der Montageaufwand der Leuchte lässt sich weitergehend reduzieren, wenn die Leiterplatte - wie erfindungsgemäß vorgesehen - einen Durchbruch oder eine Ausnehmung zur Durchführung eines Stromversorgungskabels der Leuchte aufweist; weiterhin vorteilhaft ist auf der Leiterplatte ein Geräteanschlusselement angeordnet.The installation effort of the lamp can be further reduced if the printed circuit board - as provided according to the invention - has an opening or a recess for the passage of a power supply cable for the lamp; a device connection element is also advantageously arranged on the printed circuit board.
Die Leuchte eignet sich besonders in Form einer Außenleuchte und/oder insbesondere in Form einer Fassadenleuchte.The lamp is particularly suitable in the form of an outdoor lamp and / or in particular in the form of a facade lamp.
