Abstract
Description
Bremslichter üblicher Art bestehen aus einer Glühbirne und einem Reflektor, die hinter einer roten oder durchsichtigen Abdeckscheibe angebracht sind. Brake lights of the usual type consist of a light bulb and a Reflector behind a red or transparent cover are attached.
Je höher die Bremslichter am Fahrzeug angebracht sind, desto sicherer ist es, dass sie von anderen Verkehrsteilnehmern rechtzeitig gesehen werden. Das Gehäuse für die Brems-Lichter ist ziemlich gross. Der Reflektor nimmt am meisten Platz und ist teilweise innen am Fahrzeug- Gepäckraum angebracht. Die Fahrzeugkarosserie ist an der Stelle, wo das Bremslicht, Blinklicht und das Rücklicht kommt, meistens mit einer Einbau-Öffnung ausgestattet. Diese Einbau-Öffnung ist eine Schwachstelle der Karosserie und mit viele Problemen verbunden. Das Rücklicht, Bremslicht, Blinker und Rückwärtslicht müssen abgedichtet an die Karosserie angebracht werden, sonst dringt Wasser (bei Regen oder Schnee) in den Gepäckraum ein. Das Gepäckvolumen wird durch den Reflektor ein wenig verkleinert. Diese Lichter bringen einige unnötige kg auf die Wage. The higher the brake lights are attached to the vehicle, the safer it is it that they were seen by other road users on time become. The housing for the brake lights is quite large. The Reflector takes up the most space and is partially inside the vehicle Luggage compartment attached. The vehicle body is where the brake light, flashing light and the taillight usually come with one Built-in opening. This installation opening is one Body weak point and associated with many problems. The Tail light, brake light, turn signals and rear light must be sealed the body must be attached, otherwise water penetrates (in the rain or Snow) in the luggage compartment. The luggage volume is determined by the Reflector a little smaller. These lights bring some unnecessary kg on the scales.
Der in den Patentansprüchen 1 bis 20 angegebenen Erfindung liegt das Problem zugrunde ein Bremslicht-System für Fahrzeuge zu schaffen dass ohne voluminösen Reflektor und Glühbirne auskommt und trotzdem sehr gut sichtbar ist. The invention specified in claims 1 to 20 lies there Problem to create a brake light system for vehicles that works without a voluminous reflector and light bulb and still very much is clearly visible.
Dieses Problem wird mit den in den Patentansprüchen 1 bis 20 aufgeführten Merkmalen gelöst. This problem is solved with the in claims 1 to 20 Features listed solved.
Mit der Erfindung wird ein Bremslicht-System für Fahrzeuge geschaffen, dass ein sehr kleines Volumen hat, sehr einfach und kostengünstig gebaut ist. With the invention, a brake light system for vehicles is created, that has a very small volume, built very easily and inexpensively is.
Dem Hersteller entstehen viel weniger Kosten. Der Aufwand ist auch sehr gering. Dieses Bremslicht ist sehr schnell in das Fahrzeug eingebaut. Der Energie-Verbrauch ist ebenfalls viel geringer als bei herkömmlichen Bremslichtern. Die grosse Einbau-Öffnung (für die Brems-/Rücklichter) an der Karosserie entfällt und dadurch wird die passive Sicherheit des Fahrzeugs erhöht. The manufacturer incurs much less costs. The effort is also very high low. This brake light is very quickly installed in the vehicle. The Energy consumption is also much lower than that of conventional ones Brake lights. The large installation opening (for the brake / rear lights) on the body is omitted and the passive safety of the Vehicle increased.
Neu ist bei dieser Erfindung, dass das Licht parallel zu der Lichtabdeck- Scheiben-Fläche bis zum Austrittspunkt/Fläche fliesst. Das bringt ein Vorteil mit sich, dass der Lichtstrahler platzsparend seitlich angebracht werden kann. Der Lichtstrahlrichtung ist quer zum Fahrzeug in der Lichtabdeckscheibe. Nach aussen kommt das Licht mit der Strahlrichtung längs zum Fahrzeug. What is new in this invention is that the light is parallel to the light cover Disk surface flows to the exit point / surface. That brings in The advantage of this is that the light emitter is attached laterally to save space can be. The light beam direction is transverse to the vehicle in the Lichtabdeckscheibe. The light comes out with the beam direction lengthways to the vehicle.
Ausführungsbeispiele der Erfindung werden anhand der Fig. 1 bis 5 erläutert. Es zeigen: Embodiments of the invention are explained with reference to FIGS. 1 to 5. Show it:
Fig. 1 ein Bremslicht-System mit Laser-Dioden, Fig. 1, a brake light system with laser diodes,
Fig. 2 ein Bremslicht-System mit LED-s, Fig. 2 is a brake light system with LED-s,
Fig. 3 eine Abdeckscheibe mit Lichtbrecher, Fig. 3 is a cover disc with light interrupter,
Fig. 4 eine Abdeckscheibe mit Reflektor-Streifen oder Linien, Fig. 4 is a cover disc with reflective stripes or lines,
Fig. 5 eine strukturelle Anordnung der Mikrokratzer. Fig. 5 shows a structural arrangement of the microscratches.
Fig. 6 eine Variante mit Lichtleiter. Fig. 6 shows a variant with light guide.
Das System besteht aus einem Lichtstrahler, der eine Laser-Diode oder eine herkömmliche intensiv leuchtende Leuchtdiode sein kann. Eine Leuchtdiode ist in der Regel nicht ausreichend. Es sind mehrere davon notwendig z. B. 30-200 Stück. The system consists of a light emitter, which is a laser diode or can be a conventional intensely luminous LED. A The LED is usually not sufficient. There are several of them necessary z. B. 30-200 pieces.
Das Arbeitsprinzip dieses Bremslicht ist sehr einfach: Ein Lichtstrahler 1 bzw. eine rote Laser-Diode strahlt einen gebündelten Lichtstrahl 2, die direkt in die Abdeckscheibe 3 an einem Rand 4 eindringt. Die Lichtstrahlen werden durch das Glas- oder Kunststoff-Material wie bei einem Lichtleiter geleitet. Die Bahn der Lichtstrahlen wird durch den Totalen-Reflektions- Effekt in der Abdeckscheibe gehalten. Erst wenn der Lichtstrahl einen Bereich 5 in der Abdeckcheibe trifft, die eine Lichtbrechung oder eine Lichtreflektion unter einem bestimmten Winkel-Bereich verursacht, dann verlassen die Lichtstrahlen die Glasscheibe. Dieser Punkt verhält sich als wäre er die Lichtquelle. Der Lichtbrecher kann aus mehreren parallel angeordneten "Schnittlinien" 6 bestehen und wird an die Stelle platziert, die für Bremslichter vorgesehen ist. Die einfallenden Lichtstrahlen sollen auf diese Linien unter einem Winkel zwischen 20-170° erfolgen. Wenn das Licht aus dem Laserstrahler oder den Leuchtdioden auf die Linien einfällt, leuchten sie sehr intensiv. Diese Linien oder Mikrokratzer 7 oder Einkerbungen sollen stufenartig lichteinfallend auf eine Fläche im inneren Struktur der Scheibe angeordnet werden und das auf die verschiedene Tiefen-Struktur der Scheibe, um das Licht gleichmässig auf die Scheibe zu verteilen. The working principle of this brake light is very simple: A light emitter 1 or a red laser diode emits a bundled light beam 2 , which penetrates directly into the cover plate 3 at an edge 4 . The light rays are guided through the glass or plastic material like a light guide. The path of the light rays is kept in the cover plate by the total reflection effect. Only when the light beam strikes an area 5 in the cover pane which causes light refraction or light reflection at a certain angle range, then do the light beams leave the glass pane. This point behaves as if it were the light source. The light breaker can consist of several "cut lines" 6 arranged in parallel and is placed at the location which is intended for brake lights. The incident light rays should be on these lines at an angle between 20-170 °. When the light from the laser emitter or the light-emitting diodes hits the lines, they shine very intensely. These lines or microscratches 7 or notches are to be arranged in a step-like manner so that light is incident on a surface in the inner structure of the pane, and this on the different depth structure of the pane, in order to distribute the light evenly over the pane.
Eine Variante weist mehrere dünne Silberstreifen 8 oder Linien an bestimmten Stellen, die in der Abdeckscheibe auf die Stellen integriert sind, die die Bremslichter darstellen sollen. Sie reflektieren das Licht aus dem Lichtstrahler auf die Fahrbahn. Feine Luftblasen in der Abdeckscheibe können auch für diesem Zweck benutzt werden. A variant has several thin silver strips 8 or lines at certain points, which are integrated in the cover plate at the points that are to represent the brake lights. They reflect the light from the light emitter onto the road. Fine air bubbles in the cover plate can also be used for this purpose.
Der Lichtstrahler (Laser oder LED) kann direkt an die Abdeckscheibe integriert werden. The light emitter (laser or LED) can be attached directly to the cover panel to get integrated.
Die Fig. 6 zeigt eine Variante mit Glassfasern 9. Die Glasfasern sind entlang der Scheibe angeordnet. Sie können auch in die Scheibe integriert werden. Ein Schutzmantel kann sie vor Lichtverlust schützen. An einem Ende kommt das Licht aus dem Lichtstrahler rein. Am anderen Ende tritt das Licht aus. Das Ende kann mit einer Spiegel-Fläche 10 ausgestattet werden oder das Austritts-Ende ist einfach so gebogen, das das Licht nach aussen abgegeben wird. Fig. 6 shows a variant with glass fibers 9. The glass fibers are arranged along the pane. They can also be integrated into the pane. A protective jacket can protect them from loss of light. At one end the light comes in from the light emitter. The light comes out at the other end. The end can be equipped with a mirror surface 10 or the exit end is simply curved so that the light is emitted to the outside.
