Description

Die vorliegende Erfindung betrifft eine Taschenlampe mit einem Gehäuse, einer Lichtquelle, einem Lampenkopfhals und einem Lampenkopf.The present invention relates to a flashlight with a housing, a light source, a lamp head neck and a lamp head.

Mittlerweile ist nach dem Stand der Technik eine Vielzahl unterschiedlicher Formen und Ausgestaltungen von Taschenlampen bekannt, wobei diese häufig mehrere Einzelkomponenten besitzen, die im Werk mühevoll und demzufolge mit einem hohen Arbeitsaufwand zusammengesetzt werden müssen. Hinzu kommen erhöhte Produktionskosten, die aufgrund der großen Anzahl unterschiedlicher Bauelemente relativ hoch sind.Meanwhile, a variety of different shapes and designs of flashlights is known in the art, and these often have several individual components that must be laboriously and consequently assembled at the factory with a lot of work. In addition, there are increased production costs, which are relatively high due to the large number of different components.

Eine Reduktion der Einzelkomponenten geht allerdings häufig zu Lasten einer dauerhaften Funktionsfähigkeit sowie der Haltbarkeit der Taschenlampe, da bestimmte Komponenten unterschiedliche Funktionen innerhalb der Taschenlampe parallel übernehmen müssen.However, a reduction of the individual components is often at the expense of a permanent functionality and the durability of the flashlight, as certain components have to take over different functions within the flashlight in parallel.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Taschenlampe zu schaffen, die aus möglichst wenig Einzelkomponenten zusammengesetzt ist, kompakt aufgebaut ist und gleichsam eine zuverlässige Funktionsweise liefert.It is therefore the object of the present invention to provide a flashlight, which is composed of as few individual components as possible, has a compact design and, as it were, provides reliable operation.

Diese Aufgabe wird durch die Taschenlampe nach Anspruch 1 gelöst, bei der erfindungsgemäß die Lichtquelle auf einem scheibenförmigen Halter angeordnet ist, auf dem bereichsweise wärmeleitfähige Flächen ausgebildet sind, wobei der scheibenförmige Halter zwischen dem Gehäuse und dem Lampenkopfhals formschlüssig gelagert ist. Insgesamt sind neben den standardmäßigen Komponenten, nämlich dem Gehäuse, einschließlich einer Endkappe und einer Batteriekartusche, und dem Lampenkopfhals keine weiteren Bauteile mehr notwendig, um eine zuverlässig funktionsfähige Taschenlampe zu bauen. Insbesondere kann auf ein Zusatzelement verzichtet werden, womit der scheibenförmige Halter mit der Lichtquelle mit dem Gehäuse verbunden wird.This object is achieved by the flashlight according to claim 1, wherein according to the invention, the light source is arranged on a disk-shaped holder, on the partially thermally conductive surfaces are formed, wherein the disc-shaped holder is mounted positively between the housing and the lamp head neck. Overall, in addition to the standard components, namely the housing, including an end cap and a battery cartridge, and the lamp head neck no further components longer necessary to build a reliable functional flashlight. In particular, can be dispensed with an additional element, whereby the disk-shaped holder is connected to the light source with the housing.

Weitere bevorzugte Ausführungsformen der vorliegenden Erfindung werden im Folgenden sowie in den Unteransprüchen beschrieben. Vorzugsweise wird als Lichtquelle eine Leuchtdiode (LED) verwendet, die trotz einer hohen Lichtimmission vergleichsweise wenig Wärme produziert. Zudem zeichnen sich LEDs im Vergleich zu herkömmlichen Glühbirnen durch ihre Langlebigkeit aus.Further preferred embodiments of the present invention are described below and in the subclaims. Preferably, a light emitting diode (LED) is used as the light source, which produces comparatively little heat despite a high light immission. In addition, LEDs are characterized by their longevity compared to conventional light bulbs.

Nach einer bevorzugten Ausgestaltung der vorliegenden Erfindung weist der scheibenförmige Halter gehäuseseitig kreis- und/oder ringförmig konzentrisch angeordnete elektrische Kontaktflächen auf. Der Ausgestaltung der elektrischen Kontaktflächen eignen sich besonders für solche Taschenlampen, bei denen die Batterien in einer Batteriekartusche angeordnet sind, da diese unabhängig von ihrer angularen Ausrichtung stets mit der elektrischen Kontaktfläche verbunden ist. Allerdings kann hierauf auch verzichtet werden, sofern sichergestellt ist, dass die elektrischen Kontakte zwischen Batteriekartusche und dem scheibenförmigen Halter geschlossen sind, was beispielsweise durch eine Führung der Batteriekartusche in einer gehäuseseitigen Nut erfolgen kann.According to a preferred embodiment of the present invention, the disc-shaped holder on the housing side circular and / or annular concentrically arranged electrical contact surfaces. The design of the electrical contact surfaces are particularly suitable for those flashlights in which the batteries are arranged in a battery cartridge, since it is always connected to the electrical contact surface regardless of their angular orientation. However, this can also be dispensed with, provided that it is ensured that the electrical contacts between the battery cartridge and the disc-shaped holder are closed, which can be done for example by a guide of the battery cartridge in a housing-side groove.

Vorzugsweise besitzt der scheibenförmige Halter gehäuseseitig eine ringförmige wärmeleitfähige Anlagefläche, die im eingebauten Zustand mit dem Gehäuse in Anlage ist. Durch die Ausgestaltung der wärmeleitfähigen Anlagefläche wird der gesamte Halter gekühlt, indem die Wärme an das Gehäuse wirksam abgegeben wird, was die Haltbarkeit der verwendeten Lichtquelle erhöht. Als bevorzugte Materialien eignen sich hierzu insbesondere Aluminium, Messing oder Kupfer.Preferably, the disk-shaped holder on the housing side has an annular heat-conductive contact surface, which is in the installed state with the housing in Appendix. By the design of the heat-conductive abutment surface of the entire holder is cooled by the heat is released to the housing effectively, which increases the durability of the light source used. Particularly preferred materials for this purpose are aluminum, brass or copper.

Allerdings kann nicht nur die gehäuseseitige Anlagefläche wärmeleitend ausgebildet sein. Um die Kühlung des Halters zudem zu erhöhen, ist vorteilhafter Weise vorgesehen, dass der scheibenförmige Halter eine als wärmeleitfähige Fläche ausgebildete Mantelfläche aufweist, die im eingebauten Zustand mit einem mantelförmigen Teilbereich des Gehäuses in Anlage ist. Darüber hinaus kann der scheibenförmige Halter auch lampenkopfseitig wärmeleitfähige Flächen aufweisen, die im eingebauten Zustand mit einer Anlage des Lampenkopfhalses verbunden sind.However, not only the housing-side contact surface may be formed thermally conductive. In order to increase the cooling of the holder also, it is advantageously provided that the disk-shaped holder has a lateral surface formed as a heat-conductive surface, which is in the installed state with a jacket-shaped portion of the housing in abutment. In addition, the disc-shaped holder may also have lamp-head side heat-conductive surfaces, which are connected in the installed state with a system of Lampenkopfhalses.

Um einen sicheren Halt des Halters innerhalb der Taschenlampe zu gewährleisten, besitzen zur formschlüssigen Lagerung des Halters der Lampenkopfhals und das Gehäuse je einen Anschlag, zwischen dem der scheibenförmige Halter im zusammengebauten Zustand angeordnet ist. Die entsprechenden Anlageflächen sind wärmeleitfähig ausgestaltet, damit die an der LED entstehende Wärme optimal abgeleitet werden kann.In order to ensure a secure hold of the holder within the flashlight, have for positive storage of the holder of the lamp head neck and the housing each have a stop, between which the disc-shaped holder is arranged in the assembled state. The corresponding contact surfaces are designed thermally conductive, so that the heat generated at the LED can be optimally dissipated.

Vorzugsweise sind Lampenkopfhals und Gehäuse mittels einer Gewindeverbindung miteinander verbunden, die vergleichsweise robust und zugleich einfach herzustellen ist. Zudem sind der Lampenkopf und der Lampenkopfhals ebenfalls mittels einer Gewindeverbindung verbunden, wozu der Lampenkopf und der Lampenkopfhals je einen korrespondierenden Gewindeabschnitt besitzen. Eine etwaig eingebaute Reflektorlinse kann hierzwischen eingebaut werden, so dass sie verliersicher vom Lampenkopf und Lampenkopfhals gehalten wird. Alternativ kann die Reflektorlinse auch einen eigenen Gewindeabschnitt aufweisen, so dass sie in den Lampenkopf eingeschraubt werden kann, womit der Lampenkopf auch direkt auf das Gehäuse aufgeschraubt werden kann. Hierdurch reduziert sich die Anzahl der verwendeten Bauteile um das Bauteil des Lampenkopfhalses, was weiteren Montageaufwand einspart. Selbstverständlich kann die Reflektorlinse auch durch einen separaten Halter im Lampenkopf befestigt werden, der beispielsweise ein Zylinder mit entsprechendem Außengewinde sein kann.Preferably, lamp head neck and housing are connected to each other by means of a threaded connection, which is relatively robust and at the same time easy to manufacture. In addition, the lamp head and the lamp head neck are also connected by means of a threaded connection, to which the lamp head and the lamp head neck each have a corresponding threaded portion. A possibly incorporated reflector lens can be installed between them, so that it is held captive by the lamp head and lamp head neck. Alternatively, the reflector lens may also have its own threaded portion, so that it can be screwed into the lamp head, with which the lamp head can also be screwed directly onto the housing. This reduces the number of components used to the component of the lamp head neck, which saves further assembly work. Of course, the reflector lens can also be attached by a separate holder in the lamp head, which may be, for example, a cylinder with a corresponding external thread.

Bei einer solchen Ausgestaltung sind der Lampenkopf und der Lampenkopfhals einteilig ausgebildet.In such an embodiment, the lamp head and the lamp head neck are integrally formed.
