Description
Herkömmliche Fahrradscheinwerfer bestehen aus einem Reflektor und einer kleinen Glühbirne. Diese ist mit einem Dynamo mit Hilfe von einer Litze oder Draht elektrisch verbunden. Der Schalter für das Licht entfällt. Sobald das Dynamo aktiviert ist, leuchtet der Scheinwerfer. Diese Art von Beleuchtung hat sich bis jetzt sehr gut bewährt. Die Glühbirnen sind immer besser geworden: heller und langlebiger. Trotzdem reicht manchmal die Leuchtkraft und die Helligkeit der Glühbirnen (egal welche Ausführung) oder der Halogen-Scheinwerfer nicht aus, um die anderen Verkehrsteilnehmer auf sich aufmerksam zu machen. Dadurch, dass im Strassenverkehr immer mehr Fahrzeuge mit leuchtstarken Xenon-Scheinwerfern gibt, werden die Fahrradscheinwerfer immer unauffälliger. Ein heller Fahrrad-Scheinwerfer, der mit der Helligkeit eines Xenon-Scheinwerfers vergleichbar ist, könnte viel besser von anderen Verkehrsteilnehmer wahrgenommen werden als ein Halogen-Strahler oder eine herkömmliche Glühbirne.Conventional bicycle headlights consist of a reflector and a small light bulb. This is electrically connected to a dynamo using a strand or wire. There is no switch for the light. As soon as the dynamo is activated, the headlight lights up. This type of lighting has proven to be very effective up to now. Light bulbs have become better and better: brighter and more durable. Nevertheless, sometimes the luminosity and brightness of the light bulbs (regardless of the model) or the halogen headlights are not enough to attract the attention of other road users. As there are more and more vehicles on the road with bright xenon headlights, bicycle headlights are becoming less and less conspicuous. A bright bicycle headlight that is comparable to the brightness of a xenon headlight could be much more easily noticed by other road users than a halogen spotlight or a conventional light bulb.
Es gibt heutzutage eine interessante Variante der Frontscheinwerfer für das Fahrrad: Sie besteht aus einer herkömmliche Glühbirne und einem Zusatzscheinwerfer mit LED, der ziemlich schwach leuchtet. Dieser Zusatzscheinwerfer ist nicht stark genug für eine Fahrbahn-Beleuchtung aber als Standlicht gut geeignet.Nowadays, there is an interesting variant of the headlight for bicycles: It consists of a conventional light bulb and an additional headlight with LED, which shines quite weakly. This additional headlight is not strong enough to illuminate the road but is well suited as a parking light.
Der in den Schutzansprüchen 1 bis 35 angegebenen Erfindung liegt das Problem zugrunde einen Frontscheinwerfer für Fahrrad zu schaffen, der sehr stark, extrem hell (vergleichbar mit einem Xenon-Scheinwerfer) und intensiv leuchtet (auch bei niedrigere Strom) aber keine Glühbirne oder Halogen-Strahler aufweist.The invention specified in claims 1 to 35 is based on the problem of creating a headlight for bicycles which is very strong, extremely bright (comparable to a xenon headlight) and shines intensively (even at lower current) but does not have a light bulb or halogen spotlight.
Dieses Problem wird mit den in den Schutzansprüchen 1 bis 35 aufgeführten Merkmalen gelöst.This problem is solved by the features set out in claims 1 to 35.
Vorteile der Erfindung sind:Advantages of the invention are:
- dieser Scheinwerfer leuchtet viel heller als der herkömmliche, und dadurch ist er besser von anderen Verkehrsteilnehmer wahrzunehmen,- this headlight shines much brighter than the conventional one, and is therefore easier to see by other road users,
- sehr lange Lebensdauer,- very long service life,
- geringer Stromverbrauch,- low energy consumption,
- erschütterungs-unempfindlich,- shock-resistant,
- bessere Fahrbahn-Beleuchtung,- better road lighting,
- erhöhte Sicherheit durch extreme Helligkeit,- increased safety due to extreme brightness,
- erhöhte Sicherheit durch die integrierte Lichthupe, etc.- increased safety through the integrated headlight flasher, etc.
Ausführungsbeispiele der Erfindung werden anhand der Fig. 1 bis 7 erläutert. Es zeigen:Embodiments of the invention are explained with reference to Figs. 1 to 7. They show:
Fig. 1 eine Variante mit Facettenartigen-Anordnung der LED-s, Fig. 2 eine Variante, wobei jedes LED einen kleinen Reflektor aufweist, Fig. 3 die kuppenförmige Verformungen der Scheibe, die wie Linsen wirken,Fig. 1 a variant with facet-like arrangement of the LEDs, Fig. 2 a variant where each LED has a small reflector, Fig. 3 the dome-shaped deformations of the disc, which act like lenses,

In den Figuren ist der neuartige Scheinwerfer 1 dargestellt. Dadurch, dass heutige weissen LED-s nicht so intensiv leuchtend sind, muss man mehrere davon in eine Gruppe anschliessen um den Lichtfaktor zu erhöhen. Wenn nur eine weisse LED verwendet würde, dann reicht sie nicht aus um die Strasse zu beleuchten.The figures show the new headlight 1. Since today's white LEDs are not as bright, several of them must be connected in a group to increase the light factor. If only one white LED were used, it would not be enough to illuminate the road.
Die besten Ergebnisse werden mit 12 bis 80 oder mehr LED-s 2 erzielt. Sie sind in eine Gruppe elektrisch parallel oder in Reihe, je nach Spannungshöhe angeschlossen. Der Lichtstrahl der weissen LED-s ist nicht präzise gebündelt, deswegen soll die Strahlrichtung parallel sein. Mehrere kleine Reflektoren 3 können behilflich sein. Die Schutzscheibe ist mit kleinen kuppenförmigen Verformungen 5 ausgestattet, die genau vor jedem LED in Strahlrichtung platziert sind. Sie wirken wie eineThe best results are achieved with 12 to 80 or more LEDs 2. They are connected in a group electrically in parallel or in series, depending on the voltage level. The light beam of the white LEDs is not precisely bundled, so the beam direction should be parallel. Several small reflectors 3 can be helpful. The protective screen is equipped with small dome-shaped deformations 5, which are placed exactly in front of each LED in the beam direction. They act like a
Zusatzlinse und bündeln somit die Lichtstrahlen in eine bestimmte Richtung. Diese Verformung kann auch zylindrisch geformt sein. Die zylindrische Form eignet sich sehr gut für die langen Reihen der LED-s. Die facettenförmige Variante, ist ähnlich wie der Bienestock aufgebaut. In eine facettenförmige Blende 6 sind die LED-s angebracht. Vor jedem LED ist eine kleine linsenartige Verformung 5 der Abdeckscheibe angebracht. Eine zylindrische Verformung 7 der Abdeckscheibe kann sehr gut für eine ganze LED-Reihe geeignet sein. Die Facetten verhindern das die Lichtstrahlen unkontrolliert verstreut werden. Der Scheinwerfer ist extrem flach.Additional lens and thus focus the light rays in a certain direction. This deformation can also be cylindrical. The cylindrical shape is very suitable for the long rows of LEDs. The facet-shaped variant is constructed similarly to the beehive. The LEDs are mounted in a facet-shaped aperture 6. A small lens-like deformation 5 of the cover plate is mounted in front of each LED. A cylindrical deformation 7 of the cover plate can be very suitable for an entire row of LEDs. The facets prevent the light rays from being scattered uncontrollably. The spotlight is extremely flat.
Die Leisten-Variante besteht aus mindestens eine Leiste 8 oder eine Reihe von LED-s in der 12 bis 64 Stück angebracht sind. Optimal ist jedoch eine Anzahl von 20 bis 32 Stück. Die Leiste kann senkrecht auf die Fahrrad-Vordergabel 9 oder Lenkrad angebracht werden. Der Scheinwerfer weist eine Gehäuse 14 und einen 9-V-Blockbatterie-Clip 15 auf. Die Befestigung erfolgt mittels einem oder zwei verstellbaren Bändern 10. Diese Variante kann direkt mit der Dynamo verbunden werden oder von eine Akku versorgt werden.The bar variant consists of at least one bar 8 or a row of LEDs in which 12 to 64 are attached. However, a number of 20 to 32 is optimal. The bar can be attached vertically to the bicycle front fork 9 or handlebar. The headlight has a housing 14 and a 9 V block battery clip 15. It is attached using one or two adjustable straps 10. This variant can be connected directly to the dynamo or powered by a battery.
Die Lichthupenfunktion besteht aus einem Kondensator 11 mit hoher Kapazität, einen Akku 12 oder anderen Energie-Quellen und einem Schalter 13, der den Kondensator und die Energie-Quelle wahlweise parallel oder in Reihe schalten kann. Bei parallel Schalten wird der Kondensator aufgeladen. Der Schalter ist ein Taster und schaltet beim Drücken den Kondensator, die Energie Quelle und die LED-s in Reihe. Im losgelassenen Zustand schaltet er den Kondensator parallel mit der Energie-Quelle. Auch die LED-s werden gleichzeitig von der Stromversorgung getrennt und ausgeschaltet.The headlight flasher function consists of a high-capacity capacitor 11, a battery 12 or other energy source and a switch 13 that can connect the capacitor and the energy source either in parallel or in series. When connected in parallel, the capacitor is charged. The switch is a button and when pressed, it connects the capacitor, the energy source and the LEDs in series. When released, it connects the capacitor in parallel with the energy source. The LEDs are also disconnected from the power supply and switched off at the same time.
