Description
Die
Erfindung betrifft eine Signalleuchte eines Kraftfahrzeugs mit einer
Lichtquelle in einem Gehäuse
mit einer Lichtscheibe. Eine Leuchte mit diesen Elementen ist aus
Die
Anzeigevorrichtung nach
Ein Nachteil bei diesem Stand der Technik besteht darin, daß die Niederdruckgasentladungslampe relativ viel Bauraum beansprucht. Insbesondere in Bremsleuchten von Kraftfahrzeugen steht jedoch nur ein schmaler Bauraum zur Verfügung. Ferner erfordert die hohe Versorgungsspannung der Gasentladungslampe in Bezug auf die elektrische Versorgung einen erheblichen Aufwand, und die Störungen anderer elektrischer Komponenten in dem Fahrzeug durch die elektrische Versorgung der Leuchte sind nicht vernachlässigbar.One Disadvantage of this prior art is that the low-pressure gas discharge lamp claimed a relatively large amount of space. Especially in brake lights However, only a narrow space is available from motor vehicles. Further requires the high supply voltage of the gas discharge lamp in With respect to the electrical supply a considerable effort, and the glitches other electrical components in the vehicle by the electrical Supply of the lamp are not negligible.
Andererseits ist es nicht möglich, die Niederdruckgasentladungslampe durch eine beliebige andere Lichtquelle zu ersetzen, da dies das Design des Fahrzeugs negativ beeinflussen würde: die durch die Niederdruckgasentladungslampe hervorgerufene moderne Anmutung der Leuchte ginge gänzlich verloren.on the other hand it is impossible, the low pressure gas discharge lamp by any other light source as this negatively affects the design of the vehicle would: the modern low-pressure gas discharge lamp caused Appearance of the lamp would go completely lost.
Eine
Leuchte nach dem Oberbegriff des Anspruchs 1 zeigt die
Aufgabe der Erfindung ist es, eine Alternative zu der üblichen Gasentladungslampe in einer Signalleuchte eines Kraftfahrzeugs zu schaffen, die die oben genannten Nachteile umgeht.task The invention is an alternative to the conventional gas discharge lamp in a signal light of a motor vehicle to create the top bypasses mentioned disadvantages.
Diese Aufgabe wird gelöst durch eine Leuchte mit den Merkmalen nach Anspruch 1. Bevorzugte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.These Task is solved by a luminaire with the features of claim 1. Preferred embodiments The invention are the subject of the dependent claims.
Bei der erfindungsgemäßen Lösung der Aufgabe werden als Lichtquelle mehrere nebeneinander angeordnete lichtemittierende Dioden (LED) verwendet, vor denen sich ein Lichtleiterelement aus einem transparenten Medium befindet. Das Lichtleiterelement dient im wesentlichen dazu, das Licht, das von der Lichtquelle in Richtung auf das Lichtaustrittsfenster der Leuchte abgestrahlt wird, zu bündeln und (in Querrichtung der Leuchte) zu homogenisieren.at the solution of the invention Task are as light source several juxtaposed light emitting diodes (LED) used, in front of which a light guide element from a transparent medium. The light guide element essentially serves to light the light coming from the light source Direction is emitted to the light exit window of the lamp, to bundle and (in the transverse direction of the luminaire) to homogenize.
Bei der erfindungsgemäßen Leuchte mit einer Lichtquelle in einem Gehäuse mit einer Lichtscheibe ist ein Lichtleiterelement aus einem transparenten Medium zwischen der Lichtquelle und der Lichtscheibe angeordnet ist und die Lichtquelle umfaßt mehrere nebeneinander angeordnete lichtemittierende Dioden.at the luminaire according to the invention with a light source in a housing with a lens is a light guide element made of a transparent medium between the light source and the lens is arranged and the light source comprises several juxtaposed light-emitting diodes.
Vorzugsweise umfaßt die Lichtquelle mehrere Reihen mit jeweils nebeneinander angeordneten lichtemittierenden Dioden. Dadurch wird erreicht, daß die Leuchtstärke der Leuchte optimal gewählt werden kann.Preferably comprises the light source a plurality of rows, each with juxtaposed light-emitting Diodes. This ensures that the luminosity of the Lamp can be selected optimally can.
Zur besseren Einkopplung des Lichts von der Lichtquelle ist der Lichtleiterstab aus einem transparenten Medium, der auf der Seite, die der Lichtquelle gegenüberliegt, eine Oberfläche aufweist, die mindestens Fresnel-Element umfaßt. Auch kann eine Lichtleiterscheibe aus einem transparenten Medium sein, die auf der Seite, die der Lichtquelle gegenüberliegt, eine Oberfläche aufweist, die mindestens ein Fresnel-Element umfaßt.to better coupling of the light from the light source is the light guide rod from a transparent medium, on the side opposite to the light source, a surface comprising at least Fresnel element. Also, a fiber optic disk be made of a transparent medium on the side that the Opposite light source a surface comprising at least one Fresnel element.
Statt nur eines Lichtleiterstabes kann das Lichtleiterelement zwei parallele Lichtleiterstäbe aus einem transparenten Medium umfassen. Diese können jeweils auf der Seite, die der Lichtquelle gegenüberliegt, eine Oberfläche aufweisen, die mindestens ein Fresnel-Element umfaßt.Instead of Only one light guide rod, the light guide element two parallel Light guide rods from a transparent medium. These can each be on the page, which is opposite to the light source, a surface comprising at least one Fresnel element.
Erfindungsgemäß ist das Lichtleiterelement eine Kombination aus Lichtleiterscheibe und Lichtleiterstab, wobei das Lichtleiterelement mindestens einen Lichtleiterstab aus einem transparenten Medium und eine Lichtleiterscheibe zwischen Lichtleiterstab und der Lichtquelle umfaßt.This is according to the invention Optical fiber element a combination of fiber optic disk and optical fiber rod, wherein the optical fiber element comprises at least one optical fiber rod a transparent medium and a light guide plate between Optical fiber rod and the light source includes.
Ein Vorteil der erfindungsgemäßen Leuchte besteht darin, daß das Licht durch die Verwendung des Lichtleiterelements "homogenisiert" wird. Ein weiterer Vorteil besteht darin, daß die LEDs schneller ansprechen als eine Gasentladungslampe: bei einer Geschwindigkeit von 100 km/h bedeutet die schnellere Reaktion der Lichtquelle, daß man im Durchschnitt einen Bremsweg von 8 m gewonnen hat. Ein zusätzlicher Vorteil der Erfindung besteht darin, daß man mit LEDs und Leichtleiterelement gegenüber dem Stand der Technik vorteilhafte Abstrahlungseigenschaften der Leuchte erzielt, so ist z. B. kein Reflektor mehr notwendig.One Advantage of the lamp according to the invention exists in that that Light is "homogenized" by the use of the light guide element. Another The advantage is that the LEDs respond faster than a gas discharge lamp: at one speed of 100 km / h means the faster reaction of the light source, that in Average has gained a braking distance of 8 m. An additional one Advantage of the invention is that with LEDs and light conductor element across from the prior art advantageous radiation properties of Achieved, so z. B. no reflector required.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus der folgenden Beschreibung von Ausführungsbeispielen, wobei Bezug genommen wird auf die beigefügten Zeichnungen.Further Advantages and features of the invention will become apparent from the following Description of exemplary embodiments, wherein reference is made to the accompanying drawings.

Ferner muß die Gasentladungslampe mit einer höheren Spannung betrieben werden, was einen erheblichen Aufwand in Bezug auf die elektrische Versorgung der Leuchte bedeutet und zu Störungen anderer elektrischer Komponenten in dem Fahrzeug führt.at In the prior art, the light source is a low-pressure gas discharge lamp. This has the disadvantage that they claimed a relatively large amount of space. Especially in brake lights However, only a narrow space is available from motor vehicles. Further must the Gas discharge lamp with a higher Voltage operated, which is a considerable effort in terms on the electrical supply of the lamp means and disturbances of others electrical components in the vehicle leads.
