Abstract
Description
Scheinwerfer üblicher Art für Rollstuhl bestehen aus einem Gehäuse, einem Reflektor und mindestens einer Glühbirne. Die Energie-Quelle für den Scheinwerfer wird von dem Akku des Rollstuhls abgenommen. Die Akku-Leistung der Rollstuhl ist ziemlich begrenzt, dadurch dass sie auch die Motoren des Rollstuhls betreiben muss. Headlights of a common type for wheelchairs consist of a housing, a reflector and at least one light bulb. The energy source for the headlight is removed from the wheelchair battery. The The wheelchair's battery power is quite limited in that it too must operate the wheelchair motors.
Der in den Patentansprüchen 1 bis 30 angegebenen Erfindung liegt das Problem zugrunde, eine sehr kleinen Scheinwerfer mit eine extreme Leuchtstärke zu schaffen, die auch sehr sparsam ist. This is the invention specified in claims 1 to 30 Problem underlying a very small headlamp with an extreme one To create luminosity that is also very economical.
Dieses Problem wird mit den in den Patentansprüchen 1 bis 30 aufgeführten Merkmalen gelöst. This problem is solved with the in claims 1 to 30 Features listed solved.
Mit der Erfindung wird ein Rollstuhl-Scheinwerfer geschaffen, der sehr wenig Energie verbraucht und trotzdem sehr stark beleuchtet. With the invention, a wheelchair headlight is created consumes very little energy and is nevertheless very strongly illuminated.
Vorteile der Erfindung sind:
- - der Energieverbrauch ist deutlich niedriger als bei der Glühbirne,
- - diese Scheinwerfer kann zusätzlich an verschiedene Stellen und Geräten angebracht werden oder einfach als Taschenlampe benutzt werden,
- - sie ist erschütterungsunempfindlich,
- - sie ist sehr langlebig,
- - sie ist sehr klein und sehr intensiv leuchtend,
- - im Sparmodus kann sie, je nach Ausführung und Akku-Kapazität, bis zu mehrere Wochen ununterbrochen leuchten.
- - the energy consumption is significantly lower than that of the light bulb,
- - these headlights can also be attached to different places and devices or simply used as a flashlight,
- - it is insensitive to vibrations,
- - it is very durable,
- - it is very small and shines very intensely,
- - In economy mode, depending on the version and battery capacity, it can light up continuously for up to several weeks.
Ausführungsbeispiele der Erfindung werden anhand der Fig. 1 bis 3 erläutert. Es zeigen: Embodiments of the invention are explained with reference to FIGS. 1 to 3. Show it:
Fig. 1 eine einfache Variante diese Scheinwerfer, FIG. 1 shows a simple variant such headlamps,
Fig. 2 ein Scheinwerfer, der etwas kompliziert ist und mit mehreren LED-s bestückt ist, S-LED is equipped Fig. 2 is a headlight that is somewhat complicated and having a plurality of
Fig. 3 eine Anwendungs-Möglichkeit dieser Scheinwerfer in Rollstuhl. Fig. 3 shows an application of these headlights in a wheelchair.
Dieser Scheinwerfer besteht aus einem kleinen Gehäuse 1 in der die weisse Leuchtdioden 2, ein Schalter 3 und ein Stecker 4 oder Stromverbindung mit der Rollstuhl-Akku 5 angebracht sind. Als Variante kann eine 9-V-Batterie-Andockstelle 6 oder Clip, angebracht werden. Eine Batterie- oder Akku-Schacht ist nicht integriert oder vorgesehen. Eine 9-V- Blockbatterie oder 9-V-Block-Akku kann ausserhalb des Gehäuses auf die 9-V-Baterie-Andockstelle oder Clip einfach angedockt werden. Dann kann man diesen Scheinwerfer abnehmen und als Taschenlampe benutzen. Die LED-s sind paarweise in Reihe angeschlossen. Dadurch ist die Spannung und Strom optimal für die LED-s und somit ein Strombegrenzer überflüssig. This headlight consists of a small housing 1 in which the white LEDs 2 , a switch 3 and a plug 4 or a power connection to the wheelchair battery 5 are attached. As a variant, a 9 V battery docking station 6 or clip can be attached. A battery or accumulator shaft is not integrated or provided. A 9 V block battery or 9 V block battery can easily be docked outside the housing onto the 9 V battery docking point or clip. Then you can remove this headlight and use it as a flashlight. The LEDs are connected in pairs in series. As a result, the voltage and current are optimal for the LED s and thus a current limiter is superfluous.
Diese Scheinwerfer kann über den 9-V-Batterie-Andockstelle oder Clip beliebige Arten von Akkus oder Batterien oder Batteriehalter, die mit einer 9-V-Batterieclip ausgestattet sind, angedockt werden. These headlights can be attached via the 9 V battery dock or clip any type of rechargeable battery or battery or battery holder that comes with a 9 V battery clip are equipped to be docked.
Der abnehmbare Scheinwerfer besteht lediglich aus einem kleinen Gehäuse (Kopf), in der mindestens ein weisses und intensiv leuchtendes LED angebracht ist und einem Schalter. The removable headlamp consists of only a small one Housing (head) in which at least one white and intensely shining LED is attached and a switch.
Die Spannung kann auch sehr stark variieren, soll aber um die 9-V sein. Die Variante mit konstantem Strom-Regler, kann auch viel höhere Spannungen aufnehmen. The voltage can also vary a lot, but should be around 9V. The variant with constant current regulator can also be much higher Record tensions.
Die Fig. 2 ist etwa komplizierter gebaut. Sie weist mehrere LED-s. Diese sind in zwei Reihen parallel eingeschaltet. Die zwei LED-Reihen sind nochmals in Reihe angeschlossen. Je nach gewünschter Leuchtintensität, kann ein Vorwiderstand für die LED-s eingebaut werden. Es reicht im Prinzip ein Widerstand, die eine Leistung von etwa 0,2 W bis 2 oder 10 W hat (je nach Leuchtdioden Anzahl). FIG. 2 is roughly constructed complex. It has several LED s. These are switched on in parallel in two rows. The two rows of LEDs are connected in series again. Depending on the desired light intensity, a series resistor can be installed for the LEDs. In principle, a resistor with an output of approximately 0.2 W to 2 or 10 W is sufficient (depending on the number of LEDs).
Dadurch, dass der "Kopf" dieser Scheinwerfer, bei einer Variante einen Stromregler (ein Trimmpott oder transistor-gesteuerte Spannungs-Regler) aufweist, kann sie mit einer beliebigen Spannung betrieben werden. Es reicht dass der Regler richtig eingestellt wird. Die Variante mit automatischen Regler macht das automatisch. The fact that the "head" of these headlights, in a variant one Current regulator (a trim pot or transistor-controlled voltage regulator) has, it can be operated with any voltage. It is enough that the controller is set correctly. The variant with automatic controller does that automatically.
