Bekannte Taschenleuchten in Stabform weisen in der Regel ein stabförmiges Batteriegehäuse zur Aufnahme von Stabbatterien auf, einen Schraubverschluss am Boden des Batteriegehäusen und einen abnehmbaren Reflektor, in den ein Leuchtmittel einsetzbar ist. Zur Beschaltung des Leuchtmittels mit elektrischem Strom ist auf dem Körper des Batteriegehäuses in der Regel ein Schiebeschalter vorhanden, über welchen die Taschenleuchte ein- und ausgeschaltet werden kann und in vielen Ausführungen weist dieser Schalter eine Position auf, in welcher die Taschenlampe kurzzeitig durch leichten Druck auf den Schalter eingeschaltet werden kann. Diese so aufgebauten Taschenleuchten erfüllen ihren Zweck für die meisten Anwendungen in zufriedenstellender Weise. Ältere Taschenleuchten weisen als Leuchtmittel batteriebetriebene Lampen mit einer Glühwendel auf, wobei die Glühwendel empfindlich gegenüber Schlag oder Erschütterung reagiert, in welcher die Wendel im hoch erhitzten Zustand bei Erschütterung reißt. Neuere Taschenleuchten weisen zur Erhöhung der Lichtausbeute andere Leuchtmittel auf, wie beispielsweise Xenon-Hochdruck-Lampen, in welchen statt eines Glühfadens ein Plasma aus ionisiertem Edelgas als Lichtquelle eingesetzt wird. Noch andere Taschenleuchten weisen zur weiteren Erhöhung der Lichtausbeute Leuchtdioden auf, wobei Leuchtdioden den Nachteil von monochromatischem Licht aufweisen, das bei Ausleuchtung eines Gegenstands für das menschliche Auge ungewohnte, mithin schwache, weil nur in einem Farbbereich vorhandene Kontraste erzeugt. Um diesen Nachteil zu umgehen, ist man dazu übergegangen, Taschenleuchten mit unterschiedlichen Leuchtdioden auszustatten, die in unterschiedlichen, schmalbandigen Spektralbereichen leuchten. Zur Ansteuerung dieser Leuchtdioden-Module ist es notwendig, mindestens eine Strombegrenzung zwischen Stromquelle und Leuchtdiode zu schalten. Da die unterschiedlichen Leuchtdioden-Typen unterschiedlich hell leuchten, ist es auch notwendig, den Strom der unterschiedlichen Leuchtdioden anzupassen, um ein annehmbar weiß erscheinendes und kontraststarkes Licht zu erzeugen. Die Strombegrenzung wird in der Regel elektronisch vorgenommen und die dafür notwendige Elektronik wird in einem dafür vorgesehenen Volumen der Taschenleuchte untergebracht und in der Regel mit einem Mikroschalter ein- und ausgeschaltet.Known flashlights in rod form usually have a rod-shaped battery housing for holding rod batteries, a screw cap on the bottom of the battery case and a removable reflector, in which a light source can be used. For wiring the lamp with electric current on the body of the battery case usually a slide switch is present, through which the flashlight can be switched on and off and in many versions, this switch has a position in which the flashlight briefly by light pressure the switch can be turned on. These flashlights constructed in this way fulfill their purpose satisfactorily for most applications. Older flashlights have battery-powered lamps with an incandescent filament as the light source, the incandescent coil being sensitive to shock or vibration in which the coil breaks in the highly heated state upon vibration. Newer flashlights have to increase the luminous efficacy on other bulbs, such as xenon high-pressure lamps, in which instead of a filament, a plasma of ionized noble gas is used as a light source. Still other flashlights have to further increase the luminous efficiency of light-emitting diodes, light emitting diodes having the disadvantage of monochromatic light, the unusual in illumination of an object for the human eye, thus weak, because it produces only in a color range contrasts. In order to avoid this disadvantage, it has gone over to equip flashlights with different LEDs, which light up in different, narrowband spectral ranges. To control these light-emitting diode modules, it is necessary to switch at least one current limit between the power source and light emitting diode. Since the different types of light emitting diodes light up to a different brightness, it is also necessary to adjust the current of the different light emitting diodes to produce a reasonably white and high contrast light. The current limit is usually made electronically and the necessary electronics are housed in a dedicated volume of the flashlight and usually switched on and off with a microswitch.

Aus der US-Patentdruckschrift 6,022,127 ist eine Taschenlampe bekannt, die mit einem Laserpointer kombiniert ist, wobei Laserpointer und das Leuchtmittel der Taschenlampe durch einen Platinenschalter geschaltet werden und wobei der Platinenschalter kreisrund ist und durch Verdrehung gegenüber einem Kontaktsatz die beiden Leuchtmittel in Abhängigkeit von der Drehstellung ein- und ausschaltet.From the U.S. Patent Document 6,022,127 a flashlight is known, which is combined with a laser pointer, laser pointer and the flashlamp of the flashlight are switched by a circuit board switch and wherein the circuit board switch is circular and by turning against a contact set the two bulbs in response to the rotational position on and off.

In der internationalen Patentanmeldung WO00/45086 wird eine Kombinationstaschenlampe beschrieben, die eine erste Leuchtseite mit einem gerichteten Lichtstrahl und eine zweite Leuchtseite mit einer ungerichteten Lichtquelle aufweist. Die ungerichtete Lichtquelle ist zur diffusen Beleuchtung der Umgebung gedacht, hingegen ist der gerichtete Lichtstrahl zur punktuellen Beleuchtung eines Objektes gedacht. In dieser Taschenlampe nach WO00/45086 bilden Kontaktfedern des Platinenschalters Teil eines Batteriemoduls, womit ein modularer Aufbau erreicht wird.In the international patent application WO00 / 45086 a combination flashlight is described which has a first luminous side with a directed light beam and a second luminous side with a non-directional light source. The non-directional light source is intended for the diffuse illumination of the environment, whereas the directed light beam is intended for the selective illumination of an object. In this flashlight after WO00 / 45086 form contact springs of the Circuit board switch part of a battery module, whereby a modular structure is achieved.

Schließlich ist aus der Druckschrift US 2006/0164828 eine robuste Taschenlampe mit einem Drehschalter bekannt, wobei der Drehschalter nach Art einer Kulissenmechanik auf der Innenseite des Drehschalters Kipp- oder Tastschalter der Taschenlampe auslöst.Finally, from the publication US 2006/0164828 a robust flashlight with a rotary switch known, the rotary switch triggers in the manner of a sliding mechanism on the inside of the rotary switch tilt or push button of the flashlight.

An Taschenleuchten zur Ausrüstung von Einsatzpersonal im öffentlichen Dienst, wie Polizei, Katastrophenschutz, Feuerwehr oder Sicherheitsdiensten aber auch zur Ausrüstung von Soldaten werden besonders hohe Anforderungen in Bezug auf Haltbarkeit, Verlässlichkeit, Wartungsarmut und Reparaturfähigkeit gestellt. Wichtig neben der Einstellung der Helligkeit und der Taschenlampenlichtfarbe ist, dass die Taschenleuchten unempfindlich sind gegenüber Nässe, Schlag, häufiges Schalten und intensive Nutzung mit häufigen Ein-Ausschaltvorgängen. Diese hohen Anforderungen werden in der Regel von bekannten Taschenleuchten nicht erfüllt.Flashlights for the equipment of public service personnel, such as police, civil protection, fire brigade or security services, but also for the equipment of soldiers, are subject to particularly high demands in terms of durability, reliability, low maintenance and repair capability. Important besides adjusting the brightness and the flashlight light color is that the flashlights are insensitive to moisture, shock, frequent switching and intensive use with frequent on-off operations. These high requirements are usually not met by known flashlights.

Aufgabe der Erfindung ist es deshalb, eine Taschenleuchte zur Verfügung zu stellen, welche die oben genannten hohen Anforderungen erfüllt.The object of the invention is therefore to provide a flashlight available, which meets the above-mentioned high requirements.

Die erfindungsgemäße Aufgabe wird dadurch gelöst, dass in der Eingangs erwähnten Taschenlampe die Strompulse eine Frequenz von 20 Hz bis 200 kHz aufweisen, wobei die elektronische Schaltung das Puls-Pause-Verhältnis in Abhängigkeit vom logischen Zustand variiert. Weiter vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The object of the invention is achieved in that in the input mentioned flashlight, the current pulses have a frequency of 20 Hz to 200 kHz, wherein the electronic circuit varies the pulse-pause ratio in dependence on the logic state. Further advantageous embodiments of the invention are specified in the subclaims.

Die erfindungsgemäße Taschenleuchte zeichnet sich dadurch aus, dass zur Beschaltung des Leuchtmittels, hier Leuchtdioden, eine bedruckte Leiterplatte verwendet wird, die mit Kontaktfedern in reibschlüssiger Verbindung steht. Diese Leiterplatte beschaltet die Kontaktfedern bei unterschiedlichen Drehstellungen mit einem unterschiedlichen elektrischen Strommuster. Besonders an dieser Schaltungsanordnung ist, dass diese gedruckte Leiterplatte als Schalteranordnung besonders leicht auswechselbar ist. Gerade bei Ausrüstungen von großen Mannschaften mit dem gleichen Taschenleuchten-Typ ermöglicht diese Auswechselbarkeit des im häufigen Einsatz leicht verschleißenden Schalters eine hohe Zuverlässigkeit und einfache Reparaturmöglichkeit, was die Gesamtkosten zum Unterhalt großer Mengen identischer Taschenleuchten verringert. Würde hingegen ein elektronischer Mikroschalter eingesetzt, um die Elektronik für die Stromversorgung der Leuchtdioden ein- und wieder auszuschalten, wäre es mit hin notwendig, im Reparaturfall den Mikroschalter auszuwechseln, der in der Regel fest mit dem Batteriegehäuse verbunden oder darin eingelassen ist.The flashlight according to the invention is characterized in that the circuit of the lamp, here light-emitting diodes, a printed circuit board is used, which is frictionally engaged with contact springs. This circuit board connects the contact springs at different rotational positions with a different electrical Current pattern. A particular feature of this circuit arrangement is that this printed circuit board is particularly easy to replace as a switch assembly. Especially in equipments of large crews with the same type of flashlight, this interchangeability of the frequently used in frequent use switch allows high reliability and easy repair, which reduces the overall cost of maintaining large amounts of identical flashlights. If, on the other hand, an electronic microswitch were used to switch on and off the electronics for the power supply of the light emitting diodes, it would be necessary to replace the microswitch in the event of repair, which is usually firmly connected to the battery housing or embedded therein.

In Ausgestaltung der Erfindung ist vorgesehen, dass die Kontaktfedern Teil eines Batteriemoduls sind, das in das stabförmige Gehäuse der Taschenleuchte eingeschoben wird. Zur Beschaltung der Leuchtmittel werden die Kontaktfedern als auswechselbarer Teil des Batteriemoduls gegenüber eine leicht auswechselbaren bedruckte Leiterplatte verdreht.In an embodiment of the invention it is provided that the contact springs are part of a battery module, which is inserted into the rod-shaped housing of the flashlight. To connect the bulbs, the contact springs are rotated as a replaceable part of the battery module with respect to an easily replaceable printed circuit board.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die mindestens eine Vorrichtung zur Beschaltung eine elektronische Schaltung umfasst, die zwischen das mindestens eine Leuchtmittel und mindestens eines der mindestens zwei Kontaktfedern geschaltet ist, wobei die mindestens eine Kontaktfeder elektrischen Strom zur Signalisierung eines logischen Zustands an die elektronische Schaltung weiterleitet. Je nach Stellung der Kontaktflächen auf der gedruckten Leiterbahn ergeben sich so verschiedene Schaltmuster, die von der Ansteuerelektronik für die als Leuchtmittel eingesetzten Leuchtdioden ausgewertet werden und in Abhängigkeit davon die Leuchtdioden entsprechend beschaltet. Dabei beschaltet die elektronische Schaltung in Abhängigkeit vom signalisierten logischen Zustand das mindestens eine Leuchtmittel mit kontinuierlichem elektrischem Strom oder mit elektrischen Strompulsen. Die Beschaltung mit kontinuierlichem elektrischen Strom, wobei der kontinuierliche elektrische Strom durch die elektronische Schaltung begrenzt wird, führt zur Maximalleistung und damit zur höchsten Helligkeitsstufe der so angesteuerten Leuchtdioden.In a further embodiment of the invention it is provided that the at least one device for wiring comprises an electronic circuit which is connected between the at least one lamp and at least one of the at least two contact springs, wherein the at least one contact spring electrical current for signaling a logic state to the electronic circuit forwards. Depending on the position of the contact surfaces on the printed conductor so different switching patterns, which are evaluated by the control electronics for the light-emitting diodes used as a light source and depending on the LEDs connected accordingly. In this case, the electronic circuit, depending on the signaled logic state, the at least one lamp with continuous electrical current or electrical current pulses connected. The wiring with continuous electric current, wherein the continuous electric current is limited by the electronic circuit leads to Maximum power and thus the highest brightness level of the so-called light-emitting diodes.

Um die Helligkeit der Taschenleuchte zu reduzieren, ist vorgesehen, dass die Leuchtdioden mit Strompulsen beschickt werden, wobei die Strompulse mit einer derart hohen Frequenz der Leuchtdiode zugeleitet werden, dass das menschliche Auge die durch die Strompulse erzeugten Lichtpulse nicht als Blinklicht wahrnimmt. Die Frequenz ist somit höher als etwa 20 Hz und kann bis zu 200 kHz betragen. Auch sind noch höhere Frequenzen denkbar, dann allerdings müssen Maßnahmen getroffen werden, dass die Taschenleuchte keine den Funkverkehr störende Signale aussendet, was die Taschenleuchte unnötig verteuern würde. Zur Einstellung der Helligkeit ist aber nicht die Frequenz maßgeblich, sondern das Puls-Pause-Verhältnis, durch welche die mittlere Lichtleistung der so angesteuerten Leuchtdiode eingestellt wird. Wenn im Mittel der eingeschaltete Zustand, also der Zustand, in dem der Strompuls am Leuchtmittel anliegt, 10% - 15%, der Gesamtzeit ausmacht, dann kann so eine Helligkeitsreduktion erzielt werden, die im Wesentlichen proportional zum Quotienten aus Strompuls und Summe aus Strompuls und Pausendauer eines Schaltzyklus ist. Es ist aber möglich, dass Abweichungen auftreten. Diese Abweichungen entstehen aus der Kennlinie der Empfindlichkeit des menschlichen Auges bei verschiedenen Helligkeiten, nicht reinen rechteckigen Stromimpulsen, mit denen die Leuchtmittel angesteuert werden und von komponentenspezifischen Parametern.To reduce the brightness of the flashlight, it is provided that the light-emitting diodes are charged with current pulses, wherein the current pulses are supplied to the LED at such a high frequency that the human eye does not perceive the light pulses generated by the current pulses as a flashing light. The frequency is thus higher than about 20 Hz and can be up to 200 kHz. Even higher frequencies are conceivable, but then measures must be taken that the flashlight emits no disturbing the radio traffic signals, which would unnecessarily increase the price of the flashlight. To adjust the brightness but not the frequency is decisive, but the pulse-pause ratio, by which the average light output of the thus controlled light emitting diode is set. If, on average, the switched-on state, that is to say the state in which the current pulse is applied to the luminous means accounts for 10% -15% of the total time, then a brightness reduction can be achieved which is essentially proportional to the quotient of the current pulse and the sum of the current pulse and Pause duration of a switching cycle is. But it is possible that deviations occur. These deviations arise from the characteristic curve of the sensitivity of the human eye at different brightnesses, not pure rectangular current pulses, with which the light sources are controlled, and by component-specific parameters.

Um die relative Helligkeit verschiedener, eingesetzter Leuchtmittel zu variieren, ist vorgesehen, dass sofern mindestens zwei eingesetzte Leuchtmittel vorhanden sind, die elektronische Schaltung die mindestens zwei Leuchtmittel individuell mit kontinuierlichem elektrischem Strom oder mit elektrischen Strompulsen beschickt. Dadurch können die verschiedenen Leuchtmittel in ihrer Kennlinie aneinander angepasst werden. Die Variation der relativen Helligkeit verschiedener Leuchtmittel hat neben der Anpassung der Kennlinie den Vorteil, dass die Leuchtfarbe der Taschenleuchte angepasst werden kann.In order to vary the relative brightness of different, inserted bulbs, it is provided that if at least two used bulbs are present, the electronic circuit, the at least two bulbs individually charged with continuous electric current or electric current pulses. As a result, the different lamps can be matched in their characteristic to each other. The variation of the relative brightness of different bulbs in addition to the adjustment of the characteristic has the advantage that the color of the flashlight luminous color can be adjusted.

Neben einem Betrieb mit weißer, roter, blauer, grüner und gelber Farbe ist auch ein Betrieb mit ultraviolettem Licht oder mit Infrarotlicht möglich. Hierzu hat es sich als vorteilhaft erwiesen, wenn beispielsweise im Kombinationsbetrieb mit ultraviolettem Licht, die Leuchtmittel für das ultraviolette Licht nicht gleichzeitig mit dem sichtbaren Licht gemeinsam leuchten. Beispielsweise bei der Inspektion von Tatorten unter ultraviolettem Licht zur Sichtbarmachung von Spuren ist es vorteilhaft, wenn neben dem ultraviolettem Licht auch noch sichtbares Licht scheint, aber die beiden Lichtquellen zu unterschiedlichen, wenn auch für das Auge unmerklich kurzen Zeiten leuchten, um gegebenenfalls Fluoreszenzmarker nicht durch sichtbares Licht zu stören. Im Kombinationsbetrieb mit infrarotem Licht hilft die wechselseitige Einschaltung der Leuchtmittel, einerseits einer infrarotempfindlichen Kamera die Szene auszuleuchten, auf der anderen Seite kann ein geringer Anteil sichtbaren Lichtes hinzugemischt werden, um dem menschlichen Auge Licht zum sehen zur Verfügung zu stellen. Ob die Lichtquellen wechselseitig oder nicht wechselseitig aber mit unterschiedlichem Puls-Pause-Verhältnis geschaltet werden, hängt vom gewünschten Anwendungsfall ab.In addition to operating in white, red, blue, green and yellow colors, operation with ultraviolet light or infrared light is also possible. For this purpose, it has proven to be advantageous if, for example, in combination operation with ultraviolet light, the bulbs for the ultraviolet light do not shine together with the visible light at the same time. For example, in the inspection of crime scenes under ultraviolet light for visualization of tracks, it is advantageous if in addition to the ultraviolet light also visible light shines, but the two light sources shine at different, albeit imperceptibly short, times, if necessary, to fluorescence marker not through to disturb visible light. In combination operation with infrared light, the mutual switching of the lamps, on the one hand an infrared-sensitive camera helps illuminate the scene, on the other hand, a small amount of visible light can be added to provide light to see to the human eye. Whether the light sources are switched alternately or not mutually but with different pulse-pause ratio, depends on the desired application.

Ein weiterer Betriebszustand ist der Blinkzustand, in die Taschenleuchte entweder bei einer Farbe oder mit mehr als einer Farbe wechselseitig blinkt. Sofern eine Frequenz im oberen Frequenzbereich für das menschliche Auge eingesetzt wird, und ein wechselseitiges Blinken mit mehr als einer Farbe gewählt wird, kann mit der Taschenleuchte beispielsweise beim hin- und herwedeln oder bei Erzeugung eines kreisförmigen Signals durch Schwenken im Kreis ein mehrfarbiger Kreis oder Bogen erzeugt werden. Diese Signale können als weit sichtbare und differenzierbare Not- oder Informationssignale verwendet werden. Bei Verwendung eines Blinksignals mit nur einer Farbe kann auch ein Morse-Zeichen nach dem Morse-Alphabet abgegeben werden. So hat es sich als vorteilhaft erwiesen, wenn als festes Betriebsprogramm ein S-O-S-Signal erzeugt wird, dass sich durch die Blinkfolge Kurz-Kurz-Kurz-Lang-Lang-Lang-Kurz-Kurz-Kurz, wobei "Kurz" für einen kurzen Impuls und "Lang" für einen langen Impls steht. Noch eine Möglichkeit des Einsatzes von Blinksignalen ist es, wenn ein Buchstabe nach dem Morse-Alphabet in einer ersten Farbe, ein darauf folgender Buchstabe in einer zweiten Farbe ausgesendet wird, denn dadurch hat der Empfänger die Möglichkeit, verschiedene, aufeinander folgende Buchstaben leichter von einander zu unterscheiden.Another operating state is the flashing state in which the flashlight flashes alternately, either with one color or with more than one color. If a frequency in the upper frequency range is used for the human eye, and a flashing alternately with more than one color is selected, with the flashlight, for example, in the back and forth or by generating a circular signal by panning in the circle a multicolored circle or arc be generated. These signals can be used as widely visible and differentiable emergency or information signals. When using a flashing signal with only one color, a Morse code can also be given according to the Morse alphabet. Thus, it has proved to be advantageous if a SOS signal is generated as a fixed operating program, that is indicated by the blinking sequence short-short-short-long-long-long-short-short-short, with "short" for a short pulse and "Lang" stands for a long Impls. Another possibility of using flashing signals is when a letter after the Morse alphabet in a first color, one on it the next letter is sent out in a second color, because this enables the recipient to distinguish between different consecutive letters more easily.

Das Batteriemodul 3 wird zur Montage längs in das untere Batteriegehäuse 2 eingesetzt, hingegen wird die Leuchtmittelanordnung 9 in den Reflektor 5 eingesetzt, wobei hier nicht gezeigte Mittel dafür sorgen, dass das Batteriemodul 3 drehfest in dem Batteriegehäuse 2 sitzt und dass die Leuchtmittelanordnung 9 drehfest in der Reflektoranordnung 5 sitzt. Zur Schlussmontage werden die Einheiten aus Leuchtmittelanordnung 9 und Reflektoranordnung 5 auf der einen Seite und die Anordung aus Batteriemodul 3 und Batteriegehäuse 2 miteinander über ein Gewinde 11 miteinander verschraubt. Um die bedruckte Leiterplatte 8 gegenüber den Federkontakten 7 zu verdrehen, ist vorgesehen, dass die Einheit aus Reflektoranordnung 5 und Leuchtmittelanordnung 9 im Gewinde gedreht wird. Somit wird die Gesamte erfindungsgemäße Taschenleuchte beim Schalten minimal geöffnet und wieder geschlossen. Die oben erwähnte Leiterplatte 8 wird in der nächsten Figur 2 näher dargestellt.In FIG. 1 a flashlight 1 according to the invention is shown, comprising a lower battery case 2 with molded on the surface tread grooves 3 for better tangibility of the flashlight 1. In the battery case 2 is a battery module 3 is provided for receiving batteries 4 and at its to a reflector assembly. 5 facing side having a spring contact arrangement 6, wherein the individual spring contacts 7 are in electrical contact with the batteries 4 and are movable in the longitudinal direction of the battery module 3 against a spring force. The spring contacts 7 are in the mounted state of the flashlight 1 in frictional engagement with a printed circuit board 8, which is part of a light assembly 9, in which a control electronics 10 is present, the yes after wiring pattern of their electrical inputs and outputs, the bulbs in the light assembly. 9 differently charged with electric current. The battery module 3 is used for mounting along in the lower battery case 2, however, the lamp assembly 9 is inserted into the reflector 5, wherein means not shown here ensure that the battery module 3 rotatably seated in the battery case 2 and that the lamp assembly 9 rotatably seated in the reflector assembly 5. For final assembly, the units of lamp assembly 9 and reflector assembly 5 on one side and the arrangement of battery module 3 and battery case 2 are screwed together via a thread 11 with each other. To rotate the printed circuit board 8 with respect to the spring contacts 7, it is provided that the unit of reflector assembly 5 and lamp assembly 9 is rotated in the thread. Thus, the entire pocket light according to the invention is minimally opened and closed when switching. The above-mentioned circuit board 8 will be in the next FIG. 2 shown in more detail.

In Figur 2 ist eine Aufsicht auf die Leiterplatte 8 dargestellt, die eine zentrale Kontaktfläche V+ aufweist, die beim Verdrehen der Leiterplatte 8 gegen die Kontaktfedern 7 ihren elektrischen Kontakt nicht verliert, weil sie im Drehpunkt liegt. Eine zweite Kontaktfläche G ist als konzentrischer Bogen um die zentrale Kontaktfläche V+ herum gestaltet. Eine äußerste ebenfalls mit der zentralen Kontaktfläche V+ konzentrische Kontaktfläche B1 umspannt den gleichen Winkel, jedoch ist diese Kontaktfläche B1 aufgrund ihrer äußeren Lage wesentlich größer als die Kontaktfläche G.In FIG. 2 is a plan view of the circuit board 8 is shown, which has a central contact surface V +, which does not lose their electrical contact upon rotation of the circuit board 8 against the contact springs 7, because it lies in the fulcrum. A second contact surface G is designed as a concentric arc around the central contact surface V +. An outermost also concentric with the central contact surface V + contact surface B1 spans the same angle, but this contact surface B1 is much larger than the contact surface G due to their outer layer.

Zwischen der bogenförmigen Kontaktfläche B1 am äußeren Ende und der inneren Kontaktfläche G im inneren der kreisförmigen Leiterplatte 8 befinden sich zwei konzentrische, bogenförmige Spuren, die als in der Spur unterbrochene Kontaktflächen ausgebildet sind und dazu verwendet werden, beim Verdrehen der Reflektoranordnung 5 in verschiedene Stellungen ein unterschiedliches Beschaltungsmuster der Kontaktfedern 7, die mit den Leiterplatte 8 in reibschlüssiger und damit elektrisch leitender Verbindung stehen, zu erzeugen. Die Wirkung dieser unterschiedlichen Beschaltung wird anhand der folgenden Figuren erläutert, in denen Blockschaltbilder der in der Leuchtmittelanordnung 8 untergebrachten Elektronik dargestellt sind.Between the arcuate contact surface B1 at the outer end and the inner contact surface G in the inner circuit board 8 are two concentric arcuate tracks, which are formed as discontinuous in the track contact surfaces and are used, when turning the reflector assembly 5 in different positions different Beschaltungsmuster the contact springs 7, which are in frictional and thus electrically conductive connection with the circuit board 8 to produce. The effect of this different wiring is explained with reference to the following figures, in which block diagrams of the accommodated in the light emitting device 8 electronics are shown.

In Figur 3 ist ein Blockschaltbild abgebildet, wobei das Blockschaltbild ein erstes Modul 20 umfasst, das im Wesentlichen aus der Elektronik aus dem integrierten Schaltkres IC1 und dem Mikrocontroller IC3 der Leuchtmittelanordnung 9 besteht und ein zweites Modul 21 umfasst, das aus einem Teil des Batteriemoduls 3 und der Leiterplatte in der Leuchtmittelanordnung 8 besteht. In dem Modul 21 wird durch Einstellung eines Beschaltungsmusters verschiedener Ein- und Ausgänge der Elektronik in der Leuchtmittelanordnung 8 eine Funktion der Elektronik in der Leuchtmittelanordnung 8 aktiviert. Die Elektronik in der Leuchtmittelanordnung 8 begrenzt den elektrischen Strom, der durch die mindestens eine Leuchtdiode fließt und beschaltet die mindestens eine Leuchtdiode mit kontinuierlichem Strom oder mit Strompulsen, wobei die Frequenz unter etwa 20 Hz beträgt, wenn erwünscht ist, dass durch die Strompulse ein Blinklicht erzeugt wird und über etwa 20 Hz, wenn durch die Strompulse eine Reduktion er Gesamthelligkeit erzielt werden soll. Die Frequenz etwa 20 Hz ist die Grenzfrequenz, bei der ein menschliches Auge ein blinken nicht mehr von einer geringeren mittleren Helligkeit unterscheiden kann. In spezieller Ausgestaltung der Erfindung ist vorgesehen, die beiden Frequenzen überlagert werden, also eine Frequenz unter 20 Hz und eine Frequenz deutlich über 20 Hz, wenn ein Blinken mit verringerter Helligkeit erwünscht ist.In FIG. 3 a block diagram is shown, wherein the block diagram comprises a first module 20, which consists essentially of the electronics from the integrated circuit ICs and the microcontroller IC3 of the lamp assembly 9 and comprises a second module 21, which consists of a part of the battery module 3 and the circuit board in the lamp assembly 8. In the module 21, a function of the electronics in the lighting arrangement 8 is activated by setting a wiring pattern of different inputs and outputs of the electronics in the lighting arrangement 8. The electronics in the light assembly 8 limits the electrical current flowing through the at least one light emitting diode and connects the at least one continuous current or current pulse LED, the frequency being less than about 20 Hz when it is desired to have a flashing light through the current pulses and over about 20 Hz when the total current brightness is to be reduced by the current pulses. The frequency about 20 Hz is the cutoff frequency at which a human eye can no longer distinguish a flashing from a lower average brightness. In a special embodiment of the invention, it is provided that the two frequencies are superimposed, that is to say a frequency below 20 Hz and a frequency clearly above 20 Hz, when flashing with reduced brightness is desired.

Die Zusammenwirkung der Leiterplatte 8 er Leuchtmittelanordnung 8 und der Kontaktfedern 7 wird in Figur 4 näher erläutert.The interaction of the circuit board 8 he lamp assembly 8 and the contact springs 7 is in FIG. 4 explained in more detail.

In Figur 4 ist ein Blockschaltbild unter Darstellung nur einer Leuchtdiode LED2 dargestellt, wobei ein Taster SW 1 vorgesehen ist, wenn die Leuchtdiode nur auf Anforderung kurz aufleuchten soll. Leuchtdiode LED2, Batterie U1 und Taster SW1 sind alle gemeinsam mit einem Pol an Kontakt G der Leiterplatte über eine Kontaktfeder 7 verbunden. Um die Taschenleuchte stromlos zu schalten, wird die Reflektoranordnung 5 so weit verdreht, dass die Kontaktfläche G der Leiterplatte 8 mit keinem der Kontaktfedern 7 in Kontakt steht. In allen anderen Stellungen ist die Taschenleuchte mit elektrischem Strom beschaltet, der durch die zentrale Kontaktfläche V+ und die Kontaktfläche G in die Elektronik fließt. Die äußere Kontaktfläche B der Leiterplatte 8 beschaltet den Pluspol der Leuchtdioden, wobei dieser Kontakt synchron mit der Beschaltung durch den Kontakt G läuft. Als Rest verbleiben die Kontaktspuren A und G, durch welche ein Logikmuster auf die Elektronik geschaltet wird. Die Kontaktflächen in Figur 2 zeigen drei Kombinationen, G2 und A2, A2, und die Kombination G1 und A1. Diese drei Kombinationen führen zur Beschaltung im Stand-By-Modus (Einschaltung der LED durch einen Taster), Beschaltung im Dauerzustand mit kontinuierlichem Strom und Beschaltung mit einem gepulsten Strom.In FIG. 4 is a block diagram showing only one LED LED2 shown, with a button SW 1 is provided when the LED is to light up only briefly on request. LED LED2, battery U1 and button SW1 are all connected together with a pole to contact G of the circuit board via a contact spring 7. In order to disconnect the flashlight, the reflector assembly 5 is rotated so far that the contact surface G of the circuit board 8 is in contact with none of the contact springs 7. In all other positions, the flashlight is connected to electrical current flowing through the central contact surface V + and the contact surface G in the electronics. The outer contact surface B of the circuit board 8 connects the positive pole of the light-emitting diodes, wherein this contact in synchronism with the wiring through the contact G is running. The remainder remain the contact tracks A and G, through which a logic pattern is switched to the electronics. The contact surfaces in FIG. 2 show three combinations, G2 and A2, A2, and the combination G1 and A1. These three combinations lead to the connection in stand-by mode (activation of the LED by a push-button), continuous mode wiring with continuous current and wiring with a pulsed current.

In Besonderer Ausgestaltung der Erfindung ist vorgesehen, dass die austauschbare Leuchtmittelanordnung 8 seine eigene Leiterplatte 8 aufweist, durch welche die Elektronik durch zwei Spuren mit elektrischem Strom versorgt wird, und drei puren, durch welche ein bestimmtes Strommuster auf die drei Eingänge A, G und B gegeben werden kann, um verschiedene Modi er Taschenleuchte auszuwählen, wie dauer-Ein, Blinklicht, S-O-S-Signal, verschiedenfarbiges Blinksignal verschiedener Frequenz und ein oder mehrere Zustände mit abgedunkelter Helligkeit der Leuchtmittel.In a particular embodiment of the invention, it is provided that the replaceable lamp assembly 8 has its own circuit board 8, through which the electronics are supplied by two tracks with electric current, and three pure, through which a certain current pattern on the three inputs A, G and B. can be given to select different modes he flashlight, such as continuous-on, flashing light, SOS signal, different colored flashing signal of different frequency and one or more states with darkened brightness of the bulbs.
