Die Erfindung betrifft eine Leuchte für Fahrzeuge, insbesondere Heckleuchte, mit einem Gehäuse und einer lichtdurchlässigen Abschlussscheibe sowie mit in dem Gehäuse angeordneten Reflektoren und Lichtleitkörpern.The invention relates to a lamp for vehicles, in particular a rear lamp, with a housing and a translucent lens and with in reflectors and light-guiding bodies arranged in the housing.
Eine derartige Leuchte ist aus der EP 0 780 265 A2 bekannt. Die bekannte Leuchte weist jedoch die Nachteile auf, dass separate Gehäusekammern für jede Beleuchtungsfunktion vorzusehen sind und dass die Leuchte insbesonde re in der Tiefe ein groß bauendes Gehäuse benötigt.Such a lamp is known from EP 0 780 265 A2. The well-known However, the lamp has the disadvantages that separate housing chambers for every lighting function must be provided and that the luminaire in particular re needs a large housing in depth.
Aus der DE 298 07 774 U1 ist eine Leuchte für Fahrzeuge bekannt, bei der mehrere langgestreckte, nebeneinanderliegende Lichtleiterstäbe in einem Leuchtengehäuse angeordnet sind, das von einer Abschlussscheibe abgedeckt ist. Mit Hilfe von LEDs wird an einer Stirnfläche der Lichtleiterstäbe Licht ein gekoppelt, welches dann in Richtung der Abschlussscheibe umgelenkt wird. Es ist als nachteilig anzusehen, dass wegen der geringen Lichtleistung der LEDs nur eine Lichtfunktion mit der Leuchte realisiert werden kann und dass bei der Erweiterung der Leuchte um eine zweite Lichtfunktion der Bauraum der Leuch te wesentlich vergrößert werden muss.From DE 298 07 774 U1 a lamp for vehicles is known in which several elongated, adjacent fiber optic rods in one Luminaire housing are arranged, which is covered by a lens is. With the help of LEDs, light is applied to an end face of the light guide rods coupled, which is then deflected towards the lens. It is to be regarded as disadvantageous because of the low light output of the LEDs only one light function can be realized with the luminaire and that with the Extension of the luminaire by a second light function in the installation space of the luminaire te must be increased significantly.
Die Aufgabe der Erfindung besteht darin, die gattungsgemäße Leuchte derart weiterzubilden, dass die Gesamtfläche der Abschlussscheibe bei einer Erwei terung der Anzahl der Signalfunktionen nur unwesentlich vergrößert werden muss, bei gleichzeitiger Verringerung der Bautiefe der Leuchte.The object of the invention is the generic lamp in such a way to further develop that the total area of the lens in the event of an expansion The number of signal functions can only be increased insignificantly must, while reducing the overall depth of the luminaire.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die einzelnen Re flektoren rinnenartig ausgebildet und zeilen-/spaltenförmig mit Abstand über- /nebeneinander verlaufend angeordnet sind und die Lichtleitkörper als Lichtlei terstäbe ausgebildet sind, welche in Richtung des Lichtaustritts gesehen in ei ner Ebene vor den Reflektoren und jeweils dazwischen verlaufend angeordnet sind.This object is achieved in that the individual Re reflectors are channel-shaped and line / column-shaped with spacing above / are arranged side by side and the light guide body as Lichtlei Terstellen are formed, which seen in the direction of light emission in egg ner level in front of the reflectors and arranged in between are.
Jedem der Reflektoren und Lichtleiterstäbe ist eine Lichtquelle zugeordnet, um die Leistung der Lichtquellen möglichst gering zu halten und die Wärmeent wicklung in der Leuchte zu minimieren.A light source is assigned to each of the reflectors and light guide rods to keep the power of the light sources as low as possible and the heat to minimize winding in the luminaire.
Bei einer vorteilhaften Weiterbildung der Erfindung sind die den Reflektoren zugeordneten Lichtquellen jeweils an einem Ende eines rinnenförmigen Reflek tors und die den Lichtleiterstäben zugeordneten Lichtquellen jeweils an einem Ende der Lichtleiterstäbe angeordnet.In an advantageous development of the invention, these are the reflectors assigned light sources at one end of a trough-shaped reflect tors and the light sources assigned to the light guide rods each on one End of the light guide rods arranged.
Zweckmäßigerweise ist das jeweilige Reflektorinnere in seiner Längserstrec kung konkav verlaufend ausgebildet, um die Lichtstrahlen möglichst großflä chig und homogen in Lichtaustrittsrichtung zu reflektieren.The length of the respective reflector interior is expedient Kung concavely formed to make the light rays as large as possible to reflect brightly and homogeneously in the direction of light emission.
Weiterhin ist es vorteilhaft, wenn die Lichtleiterstäbe mit optischen Mitteln ver sehen sind, die das Licht in Richtung der gewünschten Lichtaustrittsrichtung umlenken, um auch hier eine möglichst großflächige und homogene Signal funktion zu erzielen.It is also advantageous if the light guide rods ver with optical means are seen that the light in the direction of the desired light exit direction redirect in order to achieve the largest possible, homogeneous signal to achieve function.
Bei einer weiteren vorteilhaften Ausführungsform der Erfindung sind die Licht leiterstäbe an die Abschlussscheibe angespritzt, was zu einer Verringerung der Bauelemente und somit auch des Montageaufwandes führt.In a further advantageous embodiment of the invention, the light conductor bars molded onto the lens, which leads to a reduction in Components and thus the assembly effort leads.
Um den Aufbau der Leuchte zu vereinfachen ist es zweckmäßig, den Innen raum der Leuchte mittig durch ein Bauelement zu unterteilen, welches die Lichtquellen aufnimmt und das die Aufnahme der seitlich des Bauelementes erstreckenden Reflektoren und Lichtleiterstäbe aufnimmt.In order to simplify the structure of the lamp, it is advisable to use the inside to divide the space of the luminaire in the middle by a component that Light sources and that the recording of the side of the component extending reflectors and light guide rods.
Vorteilhaft sind die Lichtquellen auf Platinen angeordnete LEDs.The light sources arranged on circuit boards are advantageous LEDs.
Die Leuchte kann trotz ihrer geringen Baugröße je nach Farbgebung der ein zelnen Lichtfunktionen verschiedene, großflächige und homogene Signalfunk tionen erfüllen. Despite its small size, the lamp can be a depending on the color individual light functions different, large-area and homogeneous signal radio cations.

Die Leuchte (10) besteht aus einem Leuchtengehäuse (14) auf das mit Hilfe von Befestigungsschrauben (16) eine Abschlussscheibe (12) geschraubt ist. In dem so entstandenen Innenraum der Leuchte (10) befinden sich mehrere, ne beneinanderliegende und über Stege (26) verbundene Reflektoren (18), die sich in horizontaler Richtung von der vertikalen Mittelachse der Leuchte (10) aus erstrecken. Auf der vertikalen Mittelachse der Leuchte befinden sich Platinen (24), auf denen LEDs (22) aufgebracht sind, die Halterungen (34/36) für die Platinen (24) und die Lichtleiterstäbe (20) sowie die Zuleitungen (30) für die LEDs (22). Der Bereich der vertikalen Mittelachse wird durch eine Blende (32) überdeckt, die in den Bereichen der LEDs (22) mit Durchbrüchen versehen ist. Durch die vertikale Positionierung der Platinen (24) sind die LEDs (22) um 90° gedreht zur Abschlussscheibe (12) angeordnet und geben so Lichtstrahlen in die Reflektoren (18) und in die Lichtleiterstäbe (20) ab. Die Lichtleiterstäbe (20) sind zwischen der Abschlussscheibe (12) und den Reflektoren (18) oberhalb der zwischen den Reflektoren (18) befindlichen Stegen (26) angeordnet. In ei ner anderen Ausführungsform der Leuchte (10) sind, wie aus Fig. 7 ersichtlich, die Lichtleiterstäbe (20) direkt an die Abschlussscheibe (12) angespritzt. Die erste Lichtfunktion der Leuchte (10) wird mit Hilfe der Reflektoroptiken (18) realisiert. Die LEDs (22), die den einzelnen Reflektoren (18) zugeordnet sind, strahlen ihr Licht von einer Seite in die Reflektoren (18), die das Licht in Rich tung der Abschlussscheibe (12) reflektieren, ein. Für die zweite Lichtfunktion der Leuchte (10) wird das Licht der, den Lichtleiterstäben (20) zugeordneten LEDs (22) in die Lichtleiterstäbe (20) eingekoppelt, die das Licht dann mit Hilfe von Optikelementen ebenfalls in Richtung der Abschlussscheibe (12) umlen ken. The lamp ( 10 ) consists of a lamp housing ( 14 ) onto which an end plate ( 12 ) is screwed with the aid of fastening screws ( 16 ). In the resulting interior of the lamp ( 10 ) there are several, ne side by side and via webs ( 26 ) connected reflectors ( 18 ) which extend in the horizontal direction from the vertical central axis of the lamp ( 10 ). On the vertical center axis of the lamp there are boards (24), on which LEDs are applied (22), the brackets (34/36) for the boards (24) and the light guide rods (20) and the leads (30) for the LEDs ( 22 ). The area of the vertical central axis is covered by an aperture ( 32 ) which is provided with openings in the areas of the LEDs ( 22 ). Due to the vertical positioning of the boards ( 24 ), the LEDs ( 22 ) are arranged rotated by 90 ° to the cover plate ( 12 ) and thus emit light rays into the reflectors ( 18 ) and into the light guide rods ( 20 ). The light guide rods ( 20 ) are arranged between the cover plate ( 12 ) and the reflectors ( 18 ) above the webs ( 26 ) located between the reflectors ( 18 ). In another embodiment of the lamp ( 10 ), as can be seen in FIG. 7, the light guide rods ( 20 ) are injection molded directly onto the lens ( 12 ). The first light function of the lamp ( 10 ) is realized with the aid of the reflector optics ( 18 ). The LEDs ( 22 ), which are assigned to the individual reflectors ( 18 ), radiate their light from one side into the reflectors ( 18 ), which reflect the light in the direction of the lens ( 12 ). For the second light function of the light (10), the light is the one coupled to the light guide rods (20) associated LEDs (22) into the light guide rods (20) which ken then umlen the light by means of optical elements also in the direction of the lens (12) ,
