Description
Scheinwerfer üblicher Art für Fahrräder bestehen aus einem Reflektor und einer oder mehreren Glühbirnen, die in einem Gehäuse integriert sind. Diese Scheinwerfer haben sich ganz gut bis jetzt bewährt.Common headlights for bicycles consist of a reflector and one or more light bulbs integrated into a housing. These headlights have proven to be quite effective so far.
Diese Scheinwerfer verbrauchen ziemlich viel Energie und sind nicht ganz stossunempfindlich. Auch viel Wärme wird dadurch erzeugt.These headlights consume a lot of energy and are not completely shock-proof. They also generate a lot of heat.
Der in den Schutzansprüchen 1 bis 26 angegebenen Erfindung liegt das Problem zugrunde einen Dauer-Scheinwerfer für Fahrrad zu schaffen, der sehr stark, extrem hell (vergleichbar mit einem Xenon-Scheinwerfer) und intensiv leuchtend ist, der aber nicht zu viel Energie verbraucht.The invention specified in claims 1 to 26 is based on the problem of creating a permanent headlight for bicycles which is very powerful, extremely bright (comparable to a xenon headlight) and intensely luminous, but which does not consume too much energy.
Dieses Problem wird mit den in den Schutzansprüchen 1 bis 26 aufgeführten Merkmalen gelöst.This problem is solved by the features set out in claims 1 to 26.
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,
- erhöhte Sicherheit durch Dauerlicht und extreme Helligkeit, etc.- increased safety through continuous light and extreme brightness, etc.
Ausführungsbeispiele der Erfindung werden anhand der Fig. 1 bis 6 erläutert. Es zeigen:Embodiments of the invention are explained with reference to Figs. 1 to 6. They show:
Fig. 1 eine Variante mit Facetten-Artigen-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,
Fig. 4 die halbzylindrische Verformungen, die wie eine zylindrische Linse wirken,Fig. 4 the semi-cylindrical deformations that act like a cylindrical lens,
Fig. 5 die facettenförmige Blende,Fig. 5 the facet-shaped aperture,
Fig. 6 die Leisten-Variante.Fig. 6 the strip variant.
Die Lebensdauer der Leuchtdioden ist sehr hoch. Sie sind erschütterungsunempfindlich und verbrauchen sehr wenig Energie. Diese Eigenschaften machen sie sehr vorteilhaft für eine Nutzung in Dauerbetrieb. Sie sind sehr gut und sehr weit sichtbar. Dadurch wird die Verkehrssicherheit deutlich erhöht. Das Fahrrad wird besser von anderen Verkehrsteilnehmer gesehen (auch tagsüber).The lifespan of the LEDs is very long. They are insensitive to vibrations and consume very little energy. These properties make them very advantageous for continuous use. They are very visible and from a very long distance. This significantly increases road safety. The bike is easier to see by other road users (even during the day).
In den Figuren ist der neuartige Dauer-Scheinwerfer 1 dargestellt. Dadurch, dass heutige weissen Leuchtdioden (LED-s) 2 nicht so intensiv leuchtend sind, kann man mehrere davon in eine Gruppe anschliessen um den Lichtfaktor zu erhöhen. Wenn nur eine weisse Leuchtdiode verwendet würde, dann reicht sie nicht aus um die Strasse zu beleuchten. Sie ist aber trotzdem auch tagsüber gut sichtbar.The figures show the new permanent headlight 1. Since today's white light-emitting diodes (LEDs) 2 do not shine as intensely, several of them can be connected in a group to increase the light factor. If only one white light-emitting diode were used, it would not be sufficient to illuminate the road. However, it is still clearly visible during the day.
Die besten Ergebnisse werden mit 8 und mehr LED-s 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 4 ist mit kleinen kuppenförmigen Verformungen 5 ausgestattet, die genau vor jedem LED in Strahlrichtung platziert sind. Sie wirken wie eine 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 Leuchtdioden können auf einer Fläche angeordnet sein. Eine enge Gruppierung kann durch eine Facetten-Anordnung 6 erreicht werden. Dadurch wird die Strahldichte sehr stark erhöht. Die Facetten-Blende 7 verhindert das seitliche Lichtverstreuen. Den Frontlichtstrahlen steht sie nicht im Weg.The best results are achieved with 8 or more LEDs. 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 4 is equipped with small dome-shaped deformations 5, which are placed exactly in front of each LED in the beam direction. They act like an additional lens and thus bundle 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 light-emitting diodes can be arranged on a surface. A close grouping can be achieved by a facet arrangement 6. This greatly increases the radiance. The facet aperture 7 prevents the light from scattering to the sides. It does not get in the way of the front light rays.
Die facettenförmige Variante, ist ähnlich wie der Bienestock aufgebaut. In eine facettenförmige Blende sind die LED-s angebracht. Vor jedem LED ist eine kleine linsenartige Verformung der Abdeckscheibe angebracht. Eine zylindrische Verformung der Abdeckscheibe kann sehr gut für eine ganze LED-Reihe geeignet sein. Die Facetten verhindern das die Lichtstrahlen unkontrolliert verstreut werden.The facet-shaped variant is constructed similarly to the beehive. The LEDs are mounted in a facet-shaped cover. A small lens-like deformation of the cover plate is mounted in front of each LED. A cylindrical deformation of the cover plate can be very suitable for an entire row of LEDs. The facets prevent the light rays from being scattered uncontrollably.
Die Leisten-Variante besteht aus mindestens einer Reihe (8) von LED-s in der 5 bis 12 Stück angebracht sind.The strip variant consists of at least one row (8) of LEDs in which 5 to 12 pieces are mounted.
Der Schalter ist im Lenkrad des Fahrrads eingebaut und schaltet beim Drücken, die Energie Quelle und die Leuchtdioden-Gruppe in Reihe. Dadurch dass dieses Scheinwerfer im Dauerbetrieb eingeschaltet bleibt, ist eine Ausführung, die mit einem Rad-Sensor gekoppelt ist auch möglich. In diesem Fall, wird der Dauerscheinwerfer automatisch eingeschaltet, sobald das Fahrrad fährt. Eine Zeitverzögerung sorgt dafür, dass das Licht noch einige Zeit nachdem das Fahrrad angehalten ist, leuchtet.The switch is built into the handlebar of the bike and when pressed, switches the energy source and the LED group in series. Because this headlight remains switched on in continuous operation, a version that is coupled with a wheel sensor is also possible. In this case, the permanent headlight is switched on automatically as soon as the bike is moving. A time delay ensures that the light continues to shine for some time after the bike has stopped.
