Rück-Dauer-Licht üblicher Art für Fahrzeuge besteht aus einem Reflektor und einer oder mehreren Glühbirnen, die in einem Gehäuse integriert sind. Diese Rück-Scheinwerfer haben sich ganz gut bis jetzt bewährt. Heutzutage gibt es eine interessante Frontscheinwerfer-Variante. Diese Scheinwerfer bestehen aus einer Xenon-Röhre, die ein sehr helles Licht erzeugt.The usual type of permanent rear light for vehicles consists of a reflector and one or more light bulbs that are integrated into a housing. These rear headlights have proven to be quite effective up to now. Nowadays there is an interesting headlight variant. These headlights consist of a xenon tube that produces a very bright light.
Alle diese Scheinwerfer verbrauchen ziemlich viel Energie und sind nicht ganz stossunempfindlich. Auch viel Wärme wird dadurch erzeugt.All of these headlights consume a lot of energy and are not completely shock-proof. They also generate a lot of heat.
An vielen EU-Ländern ist das Dauerlicht schon Pflicht während des Autofahrens. Die EU-Kommission plant laut BILD-Zeitung München(13.07.2001 - Seite 1) und Süddeutsche Zeitung (14 / 15.07.2001 ; Seite V1/1) einen generellen Dauerlicht-Einbau in den Neuwagen. Die Meinung der Experten geht auseinander: Laut ADAC wird der Spritverbrauch erhöht. Die anderen meinen, dass die Sicherheit deutlich erhöht wird.In many EU countries, permanent headlights are already compulsory when driving. According to BILD newspaper Munich (July 13, 2001 - page 1) and Süddeutsche Zeitung (July 14/15, 2001; page V1/1), the EU Commission is planning to generally install permanent headlights in new cars. Experts' opinions differ: According to ADAC, this will increase fuel consumption. Others believe that safety will be significantly increased.
Der in den Schutzansprüchen 1 bis 24 angegebenen Erfindung liegt das Problem zugrunde ein Dauer-Rücklicht für Fahrzeug zu schaffen, der sehr stark, extrem hell und intensiv leuchtend ist, der aber nicht zu viel Energie verbraucht.The invention specified in claims 1 to 24 is based on the problem of creating a permanent rear light for vehicles which is very strong, extremely bright and intensely luminous, but which does not consume too much energy.
Dieses Problem wird mit den in den Schutzansprüchen 1 bis 24 aufgeführten Merkmalen gelöst.This problem is solved by the features set out in claims 1 to 24.
Vorteile der Erfindung sind:Advantages of the invention are:
- das Dauer-Rücklicht leuchtet viel heller als der herkömmliche, und dadurch ist er besser von anderen Verkehrsteilnehmer wahrzunehmen,- the permanent rear light 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 extreme Helligkeit, etc.- increased safety due to 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 und übertrifft bei weitem den Lebensdauer eines Neuwagens. 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.The lifespan of the LEDs is very long and far exceeds the lifespan of a new car. They are insensitive to vibrations and consume very little energy. These properties make them very advantageous for continuous use. They are very visible and can be seen from a very long distance. This significantly increases road safety.
In den Figuren ist das neuartige Dauer-Rücklicht 1 dargestellt. Dadurch, dass heutige Leuchtdioden (LED-s) 2 nicht so intensiv leuchtend sind, muss man mehrere davon in eine Gruppe anschliessen um den Lichtfaktor zu erhöhen. Wenn nur eine Leuchtdiode verwendet würde, dann reicht sie nicht aus um die Strasse zu beleuchten. Die Farbe der Leuchtdipden kann rot oder weiss sein. Bei weissen Leuchtdioden ist eine rote Abdeckung erforderlich. Die besten Ergebnisse werden mit 100 und mehr LED-s erzielt. Sie sind in eine Gruppe elektrisch parallel oder in Reihe, je nach Spannungshöhe angeschlossen. Bei 12 V Spannung sollen sie 3-4 Fach in Reihe angeschlossen, falls kein Strombegrenzer verwendet wird. Der Lichtstrahl der roten LED-s ist ziemlich präzise gebündelt, deswegen ist die Strahlrichtung nicht stark verstreut. Mehrere kleine Reflektoren 3 können das Licht noch stärker angrenzen. Die Schutzscheibe 4 ist mit kleinen kuppenförmigen Verformungen 5 ausgestattet, die genau vorThe figures show the new permanent rear light 1. Since today's light-emitting diodes (LEDs) 2 do not shine as intensely, several of them must be connected in a group to increase the light factor. If only one LED were used, it would not be enough to illuminate the road. The color of the LEDs can be red or white. For white LEDs, a red cover is required. The best results are achieved with 100 or more LEDs. They are connected in a group electrically in parallel or in series, depending on the voltage level. At 12 V voltage, they should be connected 3-4 times in series if no current limiter is used. The light beam of the red LEDs is bundled quite precisely, so the beam direction is not very scattered. Several small reflectors 3 can focus the light even more. The protective screen 4 is equipped with small dome-shaped deformations 5, which are located exactly in front of
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.each LED in the beam direction. They act like an 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 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 oder Insektenauge 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 a beehive or insect eye. The LEDs are mounted in a facet-shaped aperture. 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 120 bis 640 Stück angebracht sind. Optimal ist jedoch eine Anzahl von 120 bis 220 Stück pro Leiste.The strip version consists of at least one row of 8 LEDs in which 120 to 640 pieces are attached. However, a number of 120 to 220 pieces per strip is optimal.
Der Schalter ist im üblichen Bedienungsfeld des Fahrzeugs integriert 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 dem Zündschloss gekoppelt ist auch möglich.The switch is integrated into the vehicle's usual control panel and, when pressed, switches the energy source and the LED group in series. Because this headlight remains switched on continuously, a version that is coupled to the ignition lock is also possible.
Diese Dauer-Scheinwerfer kann auf der gesamten Heck-Fläche des Fahrzeugs verteilt werden. Er kann auch in das Gehäuse des herkömmlichen Scheinwerfers integriert werden oder als separater Leuchtkörper in das Fahrzeug eingebaut werden.This permanent headlight can be distributed over the entire rear area of the vehicle. It can also be integrated into the housing of the conventional headlight or installed in the vehicle as a separate light source.
