Description

Taschenlampe flashlight
Die vorliegende Erfindung betrifft eine Taschenlampe mit mehreren LEDs an der Frontseite und einer Lichtquelle an der Längsseite, insbesondere eine Taschenlampe, die es ermöglicht, eine Raumausleuchtung vorzunehmen.The present invention relates to a flashlight with a plurality of LEDs on the front side and a light source on the long side, in particular a flashlight which makes it possible to illuminate a room.
Taschenlampen werden in aller Regel dazu verwendet, um kurzzeitig bestimmte Punkte oder Gegenstände zu beleuchten oder um zum Beispiel Reparaturen an schlecht ausgeleuchteten Orten vornehmen zu können. Des weiteren finden Taschenlampen in der freien Natur Anwendung um zum Beispiel Wanderern abends die Streckenfindung zu erleichtern. Zu diesen Zwecken werden Lichtquellen benötigt, deren Lichtkegel relativ schmal ist und einen begrenzten Radius ausleuchtet. Um diesen Radius herum zeigt die Taschenlampe keine Wirkung und es dringt nur wenig Streulicht in die weitere Umgebung. Oftmals befinden sich jedoch Wanderer mehrere Tage oder gar Wochen im freien Gelände und benötigen somit abends im Zelt oder in nicht elektrifizierten Hütten eine Lichtquelle, die es ermöglich, ein Zelt oder einen Raum als Ganzes auszuleuchten. Dafür sind allerdings die herkömmlichen Taschenlampen ungeeignet, da sie nur einen begrenzten Radius ausleuchten und wenig Streustrahlung besitzen. Insofern gelingt es einer normalen Taschenlampe nicht einen Raum zu erhellen.Flashlights are usually used to briefly illuminate certain points or objects or to be able to carry out repairs in poorly lit locations, for example. Flashlights are also used in the great outdoors, for example to make it easier for hikers to find their way in the evening. For these purposes, light sources are required whose light cone is relatively narrow and illuminates a limited radius. The flashlight has no effect around this radius and only little stray light penetrates into the surrounding area. However, hikers are often in open terrain for several days or even weeks and therefore need a light source in the evening in the tent or in non-electrified huts, which makes it possible to illuminate a tent or a room as a whole. However, conventional flashlights are unsuitable for this, as they only illuminate a limited radius and have little scattered radiation. In this respect, a normal flashlight is unable to illuminate a room.
LEDs haben den Vorteil, dass sie energiesparend und langlebig sind. Allerdings streuen LEDs stark. Bei der Beleuchtungs Vorrichtung nach DE 100 04 019 zum Anstrahlen von Gegenständen wird daher jeder LED ein Gehäuse mit einer Linse zugeordnet.LEDs have the advantage that they are energy-saving and durable. However, LEDs scatter widely. In the lighting device according to DE 100 04 019 for illuminating objects, each LED is therefore assigned a housing with a lens.
Aufgabe ist es daher, eine energiesparende Taschenlampe bereitzustellen, die es ermöglicht, als leistungsfähige Taschenlampe zu wirken und zusätzlich als Lichtquelle dienen kann, um damit in geeigneter Weise Räume zu erhellen.The task is therefore to provide an energy-saving flashlight that enables it to act as a powerful flashlight and can also serve as a light source to suitably illuminate rooms.
Der Erfindung liegt die Erkenntnis zugrunde, dass diese Aufgabe durch eine Taschenlampe gelöst werden kann, die mehrere LEDs an der Frontseite und eine Lichtquelle an der Längsseite aufweist, wobei die LEDs an der Frontseite von einer Abdeckplatte geschützt sind, welche an den Stellen an welchen sie die LEDs abdeckt, jeweils ein optisches Element aufweist.The invention is based on the knowledge that this object can be achieved by a flashlight which has a plurality of LEDs on the front side and a light source on the long side, the LEDs on the front side being protected by a cover plate, which at the points at which they covers the LEDs, each has an optical element.
Der Norteil einer solchen Taschenlampe liegt darin, dass neben der normalen Funktion der Taschenlampe, nämlich das Beleuchten bestimmter Punkte oder Gegenstände, diese Taschenlampe zusätzlich als herkömmliche Lichtquelle für die Raumausleuchtung benutzt werden kann. Dies ermöglicht dem Wanderer auf den Transport einer weiteren Lichtquelle verzichten zu können, die er sonst benötigen würde um sein Zelt oder einen Raum nachts zu erhellen.The northern part of such a flashlight is that in addition to the normal function of the flashlight, namely the illumination of certain points or objects, this flashlight can also be used as a conventional light source for illuminating the room. This enables the hiker to dispense with the transport of another light source that he would otherwise need to illuminate his tent or a room at night.
Der Begriff „Längsseite" ist nicht eng auszulegen. Unter Längsseite ist die Fläche zu verstehen, die sich der ersten Lichtquelle anschließt und als Behälter des Energiespeichers dient. Im Falle einer Stabtaschenlampe, wie in den Figuren gezeigt, ist die zweite Lichtquelle am Stab der Taschenlampe untergebracht.The term “long side” is not to be interpreted narrowly. The long side is to be understood as the area that adjoins the first light source and serves as a container for the energy store. In the case of a rod torch, as shown in the figures, the second light source is on the rod of the torch accommodated.
Vorzugsweise werden die LEDs an der Frontseite und die Lichtquelle an der Längsseite von einem gemeinsamen Energiespeicher gespeist. Die Verwendung nur eines Energiespeichers hat den Vorteil, dass wenig Platz benötigt wird für die Unterbringung dieser Energiespeicher und dadurch die Taschenlampe klein und handlich gehalten werden kann.The LEDs on the front side and the light source on the long side are preferably fed by a common energy store. The use of only one energy store has the advantage that little space is required to accommodate these energy stores and the flashlight can thus be kept small and handy.
Vorzugsweise werden Batterien als Energiespeicher verwendet, wobei in diesem Zusammenhang die Batterien als alle Energiespeicher verstanden werden, die es erlauben, Energie für längere Zeit zu speichern. Denkbar sind für Energiespeicher die herkömmlichen Einwegbatterien oder die wiederaufladbaren Akkumulatoren. Untergebracht sind diese Batterien vorzugsweise im Haltegriff der Taschenlampe. Damit ein Austausch der Batterien vorgenommen werden kann, lässt sich vorzugsweise der Haltegriff für den Austausch öffnen und schließen. Werden Akkumulatoren verwendet, können diese vorzugsweise herausgenommen werden, in einer separaten Vorrichtung geladen und anschließend wieder in die Taschenlampe zurückgegeben werden. Als Ladevorrichtung können die herkömmlichen Ladegeräte dienen, die über Steckdosen die Akkumulatoren aufladen oder aber vorzugsweise ein Ladegerät, welches Solarpanele aufweist, wodurch die Akkumulatoren regeneriert werden können. Solche mit Solarpanelen ausgestatteten Ladegeräte haben den Vorteil, dass eine Regenerierung der Akkumulatoren auch durchgeführt werden kann, wenn keine herkömmliche Energiequellen, wie Steckdosen vorhanden sind, das heißt, eine Aufladung ist auch abseits der Zivilisation in der Natur möglich. Denkbar ist aber auch, dass der Akkumulator in der Taschenlampe verbleiben kann und dafür die Taschenlampe eine Vorrichtung aufweist, die es ermöglicht, den Akkumulator über eine Steckfunktion wieder aufzuladen, wobei die Taschenlampe dadurch mit externen Energiequellen, wie zum Beispiel Generatoren, Steckdosen oder Solarpanelen in Verbindung gebracht wird.Batteries are preferably used as energy stores, in this context the batteries being understood as all energy stores which allow energy to be stored for a long time. Conventional disposable batteries or rechargeable batteries are conceivable for energy storage. These batteries are preferably located in the handle of the flashlight. So that the batteries can be exchanged, the Open and close the handle for the exchange. If accumulators are used, they can preferably be removed, charged in a separate device and then returned to the flashlight. The conventional charging devices, which charge the batteries via sockets, or preferably a charger, which has solar panels, can be used as the charging device, whereby the batteries can be regenerated. Such chargers equipped with solar panels have the advantage that the rechargeable batteries can also be regenerated when there are no conventional energy sources, such as sockets, which means that charging is also possible outside of civilization in nature. However, it is also conceivable that the battery can remain in the flashlight and for this purpose the flashlight has a device which makes it possible to recharge the battery via a plug-in function, the flashlight thereby being connected to external energy sources such as generators, sockets or solar panels Is connected.
Vorzugsweise besitzen die LEDs einerseits und die Lichtquelle andererseits unabhängige Stromkreise. Dies hat den Vorteil, dass die LEDs und die Lichtquelle unabhängig voneinander betrieben werden können und dadurch der Energiespeicher vor unnötigem Energieverlust geschützt wird. Vorzugsweise besitzt jeder Stromkreis seinen eigenen Schalter zum Ein- und Ausschalten dieses Stromkreises, wobei vorzugsweise Flächenschaltelemente verwendet werden.The LEDs on the one hand and the light source on the other hand preferably have independent circuits. This has the advantage that the LEDs and the light source can be operated independently of one another, thereby protecting the energy store against unnecessary energy loss. Each circuit preferably has its own switch for switching this circuit on and off, surface switch elements preferably being used.
Dabei sind die LED 's vorzugsweise kreisförmig am vorderen Ende der Taschenlampe angebracht. Die Verwendung von LED 's hat den Vorteil, dass diese energiesparend und langlebig sind.The LEDs are preferably attached in a circle at the front end of the flashlight. The use of LEDs has the advantage that they are energy-saving and durable.
Des weiteren ist bevorzugt, dass die einzelnen LEDs unabhängig voneinander zugeschalter werden können. Diese einzelne Zuschaltung erlaubt es, die Lichtintensität den tatsächlichen Lichtverhältnissen optimal anzupassen. Darüber hinaus wird bevorzugt, dass einzelne der LEDs vermehrt Blaulicht aussenden. Ein Verwenden von nur verstärkt blauemitierenden LEDs erlaubt es, angeleuchtete Tiere schwitzen zu sehen, was bei der Tierbeobachtung oft von großer Relevanz ist. Somit ist bevorzugt, dass alle verstärkt blauemitierenden LEDs gesondert ein- und ausgeschaltet werden können, neben den anderen gesondert ein- und ausschaltbaren LEDs.It is further preferred that the individual LEDs can be switched on independently of one another. This individual connection allows the light intensity to be optimally adapted to the actual lighting conditions. In addition, it is preferred that some of the LEDs emit more blue light. Using only blue-emitting LEDs allows illuminated animals to see sweat, which is often of great relevance when observing animals. So is preferred that all blue-emitting LEDs can be switched on and off separately, in addition to the other LEDs that can be switched on and off separately.
Die LEDs werden von der Abdeckplatte geschützt. Diese Abdeckplatte sichert die Lichtquellen gegen Feuchtigkeit und Stoss. Vorzugsweise handelt es sich bei der Abdeckplatte um Polycarbonat.The LEDs are protected by the cover plate. This cover plate secures the light sources against moisture and impact. The cover plate is preferably polycarbonate.
An den Stellen, an denen die Abdeckplatte die LEDs, abschirmt, ist die Abdeckplatte solcher Natur, dass das Licht gesammelt wird. Die Sammlung ist für die LEDs notwendig, da diese extrem stark streuen. Um diesen starken Streueffekt zu kompensieren ist eine Sammlung des Lichts notwendig. Demgemäß sind die optischen Elemente an der Abdeckplatte vorzugsweise als Sammellinsen ausgebildet.In the places where the cover plate shields the LEDs, the cover plate is of such a nature that the light is collected. The collection is necessary for the LEDs because they scatter extremely strongly. In order to compensate for this strong scattering effect, a collection of light is necessary. Accordingly, the optical elements on the cover plate are preferably designed as converging lenses.
Die Lichtquelle, die an der Längsseite der Taschenlampe angebracht ist, ist vorzugsweise als Lichtleiste die längs der Längsachse entlang läuft, ausgebildet. Dies hat den Vorteil, dass die Lichtquelle nicht nur punktförmig ist, und dadurch nicht nur ein Lichtkegel ausgebildet wird, sonder ein breites Streulicht zur Verfügung steht.The light source, which is attached to the longitudinal side of the flashlight, is preferably designed as a light bar that runs along the longitudinal axis. This has the advantage that the light source is not only point-shaped, and therefore not only a light cone is formed, but also a wide scattered light is available.
Denkbar ist aber auch, dass die Lichtquelle als Lichtleiste senkrecht zur Längsachse verläuft und einen Kreis bildet. Denkbar ist des weiteren, dass als Lichtquelle in beiden Fällen (längs bzw. senkrecht der Längsachse) keine relativ schmale Lichtleiste verwendet wird, sondern eine breite Lichtfläche. Dadurch würde im Falle der senkrechten Anordnung der Lichtquelle zur Längsachse eine geschlossene Mantelfläche entstehen.It is also conceivable that the light source runs as a light bar perpendicular to the longitudinal axis and forms a circle. It is also conceivable that in both cases (along or perpendicular to the longitudinal axis) the light source used is not a relatively narrow light bar, but rather a broad light area. This would result in a closed lateral surface in the case of a vertical arrangement of the light source with respect to the longitudinal axis.
Vorzugsweise handelt es sich bei der Lichtquelle um eine Leuchtstoffröhre, vorzugsweise mit niedrigem Energieverbrauch. Dies wiederum hat den Vorteil, dass diese Lichtquelle über einen längeren Zeitraum verwendet werden kann ohne dass der Energiespeicher unnötig belastet wird.The light source is preferably a fluorescent tube, preferably with low energy consumption. This in turn has the advantage that this light source can be used over a longer period of time without unnecessarily stressing the energy store.
Vorzugsweise tritt die Lichtquelle zumindest partiell aus dem Gehäuse der Taschenlampe heraus um dadurch die Lichtquelle, die in alle Richtungen strahlt, besser nutzen zu können. Vorzugsweise ist die Lichtquelle an der Längsseite ebenfalls durch eine Abdeckplatte geschützt, um sie so gegen Feuchtigkeit und Stoß zu sichern. Vorzugsweise besteht die Abdeckung aus Polycarbonat.The light source preferably emerges at least partially from the housing of the flashlight in order to be able to use the light source, which radiates in all directions, better. Preferably, the light source on the long side is also protected by a cover plate in order to secure it against moisture and shock. The cover is preferably made of polycarbonate.
Vorzugsweise sind hinter den LEDs der Frontseite und der Lichtquelle an der Längsseite Reflektoren vorgesehen, um die Lichtquellen effektiver ausnützen zu können.Reflectors are preferably provided behind the LEDs on the front side and the light source on the long side, in order to be able to use the light sources more effectively.
Vorzugsweise können alle LEDs einzeln ausgetauscht werden, um dadurch die Lebenszeit der Taschenlampe deutlich erhöhen zu können.All LEDs can preferably be replaced individually in order to be able to significantly increase the life of the flashlight.
Im folgenden wird ein Ausführungsbeispiel unter den Hinweis auf die beigefügten Zeichnungen näher beschrieben.In the following an embodiment will be described with reference to the accompanying drawings.

Taschenlampe (1) besitzt am vorderen Ende der Taschenlampe Lichtquellen (2), vorzugsweise LED 's, die kreisförmig um eine zentrale Lichtquelle (2) angeordnet sind. Diese Lichtquellen werden von einer Abdeckplatte (5) geschützt. In diese Abdeckplatte (5) sind optische Elemente (6) z.B. Sammellinsen eingearbeitet, die an den Stellen angebracht sind, die den Lichtquellen (2) gegenüber liegen. Dadurch kann das Streulicht gesammelt werden, so dass eine gute Beleuchtung von Gegenständen oder Punkten möglich ist. An der Längsseite der Taschenlampe befindet sich die Lichtquelle (3), die als Lichtleiste ausgebildet ist. Diese Lichtleiste wird durch eine Abdeckplatte (nicht eingezeichnet) geschützt. Die Lichtquellen (2;3) können durch die Flächenschaltelemente (7;8) jeweils unabhängig voneinander ein- und ausgeschaltet werden. Des weiteren besitzt die Taschenlampe (1) eine abnehmbare Abdeckung (9), unter dem sich die Energiespeicher (4) befinden und somit herausgenommen werden können. Denkbar ist auch, dass statt der Abdeckung (9) ein Drehverschluss (10) vorhanden ist, der aufgeschraubt werden kann und aus dem dann die Energiespeicher (4), vorzugsweise Batterien, entnommen werden können. Flashlight (1) has light sources (2), preferably LEDs, at the front end of the flashlight, which are arranged in a circle around a central light source (2). These light sources are protected by a cover plate (5). Optical elements (6), for example converging lenses, are incorporated into this cover plate (5), which are attached at the points opposite the light sources (2). This allows the scattered light to be collected, so that good lighting of objects or points is possible. The light source (3), which is designed as a light bar, is located on the long side of the flashlight. This light bar is protected by a cover plate (not shown). The light sources (2; 3) can be switched on and off independently of one another by the surface switching elements (7; 8). Furthermore, the flashlight (1) has a removable cover (9), under which the energy stores (4) are located and can thus be removed. It is also conceivable that instead of the cover (9), a twist lock (10) is present, which can be screwed on and from which the energy store (4), preferably batteries, can then be removed.
