Hs-Hv-QIHs-Hv-QI
Die Neuerung betrifft eine Taschenlampe deren Leuchtmittel über Taster/Schalter mittels elektrischer Energie betrieben werden, wobei die Energiequelle eine in das Taschenlampengehäuse einfügbare chemische Batterie oder ein hierin eingefügter wiederaufladbarer Akkumulator ist.The innovation concerns a flashlight whose lighting means are operated via buttons/switches using electrical energy, whereby the energy source is a chemical battery that can be inserted into the flashlight housing or a rechargeable accumulator inserted therein.
Die bekannten Taschenlampen der beschriebenen Art setzen als Leuchtmittel Glühlfadenlampen, vorzugsweise, der längeren Lebensdauer und des besseren Wirkungsgrades wegen, gasgefüllte Glühlampen ein. Die Lichtintensität dieses Leuchtmittels ist recht hoch, so dass mit derart ausgestatteten Taschenlampen auch weit entfernte Objekte ausgeleuchtet werden können. Allerdings ist der Wirkungsgrad dieses Leuchtmittels niedrig, da nur etwa 10% des elektrischen Stromes in Licht umgesetzt werden und der Rest als Wärme verloren geht.The well-known flashlights of the type described use incandescent filament lamps as their light source, preferably gas-filled light bulbs because of their longer lifespan and better efficiency. The light intensity of this light source is quite high, so that flashlights equipped in this way can also illuminate objects that are far away. However, the efficiency of this light source is low, since only about 10% of the electrical current is converted into light and the rest is lost as heat.
Als Leuchtmittel bekannt sind auch Licht emittierende Dioden (LEDs) die gegenüber den Glühlampen nur einen sehr geringen Stromverbrauch aufweisen, deren Lichtintensität jedoch auch entsprechend gering ist. Sie dienen daher insbesondere als Signalmittel, obwohl mit ihnen auch ein, allerdings begrenzter, Nahbereich ausgeleuchtet werden kann.Light-emitting diodes (LEDs) are also known as lighting devices. They use very little power compared to incandescent lamps, but their light intensity is also correspondingly low. They are therefore used primarily as signaling devices, although they can also be used to illuminate a close-up area, albeit a limited one.
Aufgabe der Neuerung ist es, eine Möglichkeit anzugeben, wie das Ausleuchten sowohl ferner wie auch naher Objekte mit einer einzigen Taschenlampe bei gutem Wirkungsgrad, also mit geringem Stromverbrauch und damit über einen langen Zeitraum, durchgeführt werden kann.The aim of the innovation is to provide a way of illuminating both distant and close objects with a single flashlight with good efficiency, i.e. with low power consumption and thus over a long period of time.
Erreicht wird das nach der Neuerung dadurch, das Leuchtmittel sowohl eine Glühlampe wie auch mindestens eine Licht emittierende Diode (LED) ist. Diese Leuchtmittel können gemeinsam oder wahlweise einzeln mittels Schalter oder Taster mit der Energiequelle verbunden werden, wobei es sich empfiehlt die Glühlampe mit dem hohen Stromverbrauch nur über den Taster zu betreiben. Dadurch wird eine schnelle Entladung der Batterie bzw. des Akkumulators vermieden. Vorteilhafterweise wird die Glühlampe zentral in einem Reflektor angebracht, und werden die Dioden kranzförmig um einen solchen Reflektor angeordnet.According to the innovation, this is achieved by the light source being both a light bulb and at least one light-emitting diode (LED). These light sources can be connected to the energy source together or individually using a switch or button, although it is recommended that the light bulb with the high power consumption should only be operated using the button. This prevents the battery or accumulator from discharging quickly. The light bulb is advantageously mounted centrally in a reflector and the diodes are arranged in a ring around such a reflector.

Mit einer Taschenlampe der neuerungsgemäßen Art ist es sowohl möglich einen Fernbereich, wie auch einen Nahbereich, beispielsweise zur Durchführung manueller Arbeiten„ mit geringst möglichem Stromverbrauch und damit über eine lange Gebrauchsdauer auszuleuchten.With a flashlight of the new type, it is possible to illuminate both a distant area and a close area, for example for carrying out manual work, with the lowest possible power consumption and thus over a long period of use.
Auf der Zeichnung ist eine Taschenlampe der beschrieben Art dargestellt. In einem Lampengehäuse 1 sind Batterien 2 (oder Akkumulatoren) untergebracht. Über Schalter 3 oder Taster 4 sind im Kopf der Taschenlampe angeordnete Leuchtmittel 5,6 mit dieser Batterie zu verbinden. Hierbei setzt der Taster 4 lediglich die in einem Reflektor (7) angeordnete Glühlampe 6 unter Strom, während mit dem Schalter 3 sowohl die Dioden 5 wie auch die Glühlampe 6 eingeschaltet werden können.The drawing shows a flashlight of the type described. Batteries 2 (or accumulators) are housed in a lamp housing 1. The light sources 5, 6 arranged in the head of the flashlight are connected to this battery via a switch 3 or button 4. The button 4 only supplies current to the light bulb 6 arranged in a reflector (7), while the switch 3 can be used to switch on both the diodes 5 and the light bulb 6.
