Abstract

The invention relates to a lighting or illuminating device, especially for motor vehicles, having a light source and a light exit surface or a light exit plane according to the generic part of Patent Claim 1. In a lighting or illuminating device of this type, the signal image function of the device is configured in a non-glare manner while retaining an optimal illumination of the roadway. To this end, the invention provides that the light exit plane is comprised of a middle area (10) which permits a part of the available light efficiency of the light source to pass through in a manner in which it is nearly unattenuated, and is comprised of an outer area (20) which encircles said middle area in a ring-shaped manner. Said outer area permits the available remaining part of the light efficiency to pass through in a manner in which it is slightly attenuated.

Description

Licht- bzw. Beleuchtungseinrichtung, insbesondere für Kraftfahrzeuge Light or lighting device, in particular for motor vehicles
Die Erfindung betrifft eine Licht- bzw. Beleuchtungseinrichtung, insbesondere für Kraftfahrzeuge mit einer Lichtquelle und einer Lichtaustrittsfläche bzw. einer Lichtaustrittsebene, gemäß Oberbegriff des Patentanspruches 1.The invention relates to a light or lighting device, in particular for motor vehicles, with a light source and a light exit surface or plane, according to the preamble of claim 1.
Bei Beleuchtungseinrichtungen, insbesondere für Kraftfahrzeuge, unterscheidet man grundsätzlich zwischen Projektionstyp und Refiexionstyp. Die grundsätzliche Bauform bei einer Beieuchtungseinrichtung nach dem Reflexionstyp ist, daß am Fuße der Brenn- bzw. Lichtquelle dieselbe von einem parabolischen Reflektor umgeben ist. Vor dem Reflektor, d.h., in denjenigen Halbraum, in den das Licht abgestrahlt wird, ist eine Halteeinrichtung, welche in der Regel mit einer Linse versehen ist, angeordnet. Dabei wird versucht, das Licht gleichförmig aus der Reflektorzone auszukoppeln und auf das Linsensystem zu bringen. Weitere bekannte Varianten bestehen darin, zwischen Reflektor und Linse einen zyiinder- förmigen Mantel vorzusehen, der Streulicht einfängt. Wesentlich ist dabei, daß die Schein- werferprojektionslinse bei bekannten Scheinwerfern oder Beleuchtungseinrichtungen das gesamte verfügbare Licht einsammelt und nach vorne werfen soll. Die lichtemittierende Fläche bzw. die Lichtaustrittsfläche oder Lichtaustrittsebene wird durch die Außenfläche der Scheinwerferiinse gegeben.With lighting devices, in particular for motor vehicles, a basic distinction is made between projection type and reflection type. The basic design of an illumination device according to the reflection type is that it is surrounded by a parabolic reflector at the foot of the burning or light source. A holding device, which is usually provided with a lens, is arranged in front of the reflector, i.e. in the half space into which the light is emitted. An attempt is made to decouple the light uniformly from the reflector zone and to bring it onto the lens system. Further known variants consist in providing a cylinder-shaped jacket between the reflector and lens, which captures stray light. It is essential that the headlight projection lens in known headlights or lighting devices collect all the available light and throw it forward. The light-emitting surface or the light exit surface or light exit plane is given by the outer surface of the headlight lens.
Einem Fahrzeugscheinwerfer kommt zum einen die Aufgabe zu, insbesondere in Fahrtrichtung eine Ausleuchtung der Fahrbahn bei Dunkelheit zu gewährleisten und gleichzeitig für entgegenkommende Fahrzeuge das Signalbild für ein herannahendes Fahrzeug darzustellen. Mit dieser Doppelaufgabe bedacht sind im Stand der Technik vielfaches Scheinwerferanordnungen bekannt, bei denen darauf geachtet wird, das Licht möglichst gut zu bündeln. Dies wiederum zeigt vielfache Nachteile. Zum einen wird zwar der nach vorne gerichtete Raum vor dem Fahrzeug bei Dunkelheit für den Fahrzeugführer selbst gut ausgeleuchtet, jedoch ist die zum Ausleuchten verwendete Lichtmenge bzw. Lichtenergie auch diejenige, die das Signalbild darstellt. Dies führt dazu, daß ein gut ausleuchtender Scheinwerfer in den meisten Fällen den Gegenverkehr blendet. Aus diesem Grund sind im Stand der Technik Scheinwerferanordnungen zur Vermeidung von Blendeffekten bekannt.On the one hand, a vehicle headlight has the task of ensuring illumination of the roadway in the dark, in particular in the direction of travel, and at the same time of displaying the signal image for oncoming vehicles for an approaching vehicle. With this double task in mind, multiple headlight arrangements are known in the prior art, in which care is taken to focus the light as well as possible. This in turn shows multiple disadvantages. On the one hand, the forward-facing space in front of the vehicle is well illuminated in the dark for the driver, but the amount of light or light energy used to illuminate is also that which represents the signal image. This means that a well-illuminating headlamp dazzles oncoming traffic in most cases. For this reason, headlight arrangements for avoiding glare effects are known in the prior art.
Aus der DE 19 625 923 A1 ist ein Scheinwerfer für Fahrzeuge bekannt, welcher nach dem Projektionstyp arbeitet. Der Scheinwerfer besteht dabei aus einem Reflektor, einer Lichtquelle, einer Blende und einer nachgeschalteten Linse. Der Lichtstrom wird dabei in seiner vertikalen und horizontalen Grundeinstellung bezüglich einer Scheinwerferlängsachse durch vertikale und horizontale Verschiebung der Linse eingestellt. Dabei kann die besagte Linse exzentrisch zur Scheinwerferlängsachse gelagert sein und im wesentlichen um die Scheinwerferlängsachse drehbar angeordnet sein. Hierbei steht die besagte Lichtstromver- teiiung als solches im Vordergrund, insgesamt wirft der Scheinwerfer die gesamte Lichtmenge nach vorne aus. Es wird dabei, wie auch in anderen bekannten Systemen versucht, möglichst viel der Lichtmenge auf die Fahrbahn in einem nach unten gerichteten Winkel abzustrahlen. Hierdurch versucht man, die Blendung des Gegenverkehrs durch eine entsprechende Abwendung des Lichtkegels zu erreichen.From DE 19 625 923 A1 a headlight for vehicles is known which works according to the projection type. The headlamp consists of a reflector, a light source, an aperture and a downstream lens. The luminous flux is adjusted in its vertical and horizontal basic setting with respect to a longitudinal axis of the headlamp by vertical and horizontal displacement of the lens. Said lens can be mounted eccentrically to the longitudinal axis of the headlamp and can be arranged essentially rotatable about the longitudinal axis of the headlamp. The foregoing luminous flux distribution as such is in the foreground, overall the headlight throws the entire amount of light forward. As in other known systems, an attempt is made to emit as much of the amount of light onto the roadway as possible at a downward angle. In this way, an attempt is made to dazzle oncoming traffic by appropriately turning away the light cone.
Aus der DE 19 715 6 93 A 1 ist eine Leuchte für ein Fahrzeug bekannt, bei weichem eine Abschirmung in dem Lichtweg zwischen Reflektor und Linse angeordnet wird, die eine Abschattung bzw. Veränderung der Lichtverteilung bewirkt. Dabei soll erreicht werden, daß der Lichtstrahl im Randbereich eine verringerte Schärfe aufweist. Dies heißt mit anderen Worten, daß der Lichtstrahl von einem inneren Kernbereich nach außen hin diffus gestreut wird.From DE 19 715 6 93 A 1 a lamp for a vehicle is known in which a shield is arranged in the light path between the reflector and lens, which causes shading or change in the light distribution. It should be achieved that the light beam has a reduced sharpness in the edge area. In other words, this means that the light beam is diffusely scattered outwards from an inner core area.
Da das Abschirmelement jedoch im direkten Lichtweg platziert ist, wird ein nicht unwesentlicher Teil des verfügbaren Kernlichtes, also nicht des Streulichtes, abgeschattet und steht für die reine Ausleuchtfunktion nicht mehr zur Verfügung.However, since the shielding element is placed in the direct light path, a not insignificant part of the available core light, i.e. not the scattered light, is shaded and is no longer available for the pure illumination function.
Aus der DE 41 02 586 A1 ist ein Scheinwerfer bekannt, der mit einer Korrektureinrichtung zum Korrigieren einer Lichtverteilungscharakteristik versehen ist, welche durch eine Neigung eines Karosserieteils bezüglich einer Fahrbahn verursacht wird. Hierzu werden Abdeckmittel verwendet, die sich mit der Neigung des Fahrzeuges oder des Karosserieteiles verändern. Eine solche Bauart wird bei Motorrädern eingesetzt. Aber auch hier wird die Blendung in den Gegenverkehr nicht vermieden.DE 41 02 586 A1 discloses a headlamp which is provided with a correction device for correcting a light distribution characteristic which is caused by an inclination of a body part with respect to a roadway. For this purpose, cover means are used which change with the inclination of the vehicle or the body part. Such a design is used in motorcycles. But here, too, the glare in oncoming traffic is not avoided.
Aus der europäischen Patentanmeldung EP 06 23 780 A2 ist eine Fahrzeugscheinwerfer- projektionslinse bekannt, die zur Erzeugung eines Abblendlichtmusters so ausgestaltet ist, daß die konvexe Abstrahlfläche der Linse unterschiedlich abbildende Abschnitte aufweist, 3 wobei ein oberhalb der Horizontalebene durch die optische Achse liegender oberer Abschnitt und ein unterhalb dieser Horizontalebene liegender unterer Abschnitt vorgesehen ist, wobei zumindest zwei untere Abschnitte vorgesehen sind, von denen einer eine über die Horizontalebene zum seitlichen Linsenrand hin anstehende obere Begrenzung aufweist, bzw. eine kontinuierlich verschieden abbildende Oberfläche vorgesehen ist. Auch hierbei wird der Lichtstrahl insgesamt in Segmente aufgeteilt. Dies führt lediglich zur einer Auffächerung des eigentlichen Lichtkegels. Die Vermeidung einer Blendwirkung ist auch hierbei nicht gewährleistet.From the European patent application EP 06 23 780 A2 a vehicle headlight projection lens is known which is designed to generate a low beam pattern so that the convex emission surface of the lens has different imaging sections, 3, an upper section lying above the horizontal plane through the optical axis and a lower section lying below this horizontal plane being provided, at least two lower sections being provided, one of which has an upper boundary protruding beyond the horizontal plane towards the lateral lens edge, or a continuously different imaging surface is provided. Here, too, the light beam is divided overall into segments. This only leads to a fanning out of the actual light cone. Avoiding glare is also not guaranteed here.
Ausgehend von dieser Problematik liegt der vorliegenden Erfindung somit die Aufgabe zugrunde, eine Licht- bzw. Beleuchtungseinrichtung, insbesondere für Kraftfahrzeuge der gattungsgemäßen Art dahingehend weiterzubilden, daß unter Beibehaltung einer optimalen Ausleuchtung der Fahrbahn die Signalbildfunktion der Einrichtung blendfrei ist.Based on this problem, the present invention is based on the object of further developing a light or lighting device, in particular for motor vehicles of the generic type, in such a way that the signal image function of the device is glare-free while maintaining optimum illumination of the roadway.
Die gestellte Aufgabe wird bei einer Licht- bzw. Beleuchtungseinrichtung, insbesondere für Kraftfahrzeuge, gemäß Oberbegriff des Patentanspruches 1, erfindungsgemäß dadurch gelöst, daß die Lichtaustrittsebene aus einem einen Teil der verfügbaren Lichtausbeute der Lichtquelle nahezu ungeschwächt durchlassenden mittleren Bereich, sowie einem den besagten mittleren Bereich ringförmig umgebenden äußeren Bereich besteht, welcher den verfügbaren anderen Teil der Lichtausbeute lediglich geschwächt durchläßt.The object is achieved in a light or lighting device, in particular for motor vehicles, according to the preamble of patent claim 1, according to the invention in that the light exit plane consists of a part of the available light output of the light source, which allows the central source to pass almost unattenuated, as well as a said central region there is a ring-shaped surrounding outer area, which only allows the other part of the light output available to be weakened.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den übrigen abhängigen Ansprüchen angegeben.Further advantageous embodiments of the invention are specified in the remaining dependent claims.
Kern der Erfindung besteht darin, daß der mittlere Bereich vorzugsweise bzw. in einem Ausführungsbeispiel auch mit Linse versehen, den Hauptanteil des verfügbaren Lichtes zur Ausleuchtung der Fahrbahn auf dieselbe richtet, und der äußere Bereich das verbleibende Rest- und/oder Streulicht verwendet, welches Gegenverkehr als Signalbild zugewandt ist. Durch die Verwendung des gestreuten, nicht mehr in den Hauptlichtkegel zurückreflektierten Lichtanteiles durch einen äußeren Ringbereich, der das besagte Licht dem Gegenverkehr zuwendet, ist dasselbe blendfrei abgeschwächt. D.h., dasjenige Licht, was über den äußeren Ringbereich der Lichtaustrittsebene emittiert, stellt lediglich das Signalbild dar.The essence of the invention is that the central area is preferably or in one embodiment also provided with a lens, the main part of the available light for illuminating the road is directed at the same, and the outer area uses the remaining and / or scattered light which is oncoming traffic is facing as a signal image. The use of the scattered light component, which is no longer reflected back into the main light cone, through an outer ring area, which turns the light in question to oncoming traffic, attenuates it without glare. This means that the light that emits via the outer ring area of the light exit plane only represents the signal image.
Die weitergehende blendfreie Abschwächung dieses besagten Lichtteiles in dem besagten ringförmigen Außenbereich kann dadurch erreicht werden, daß die Innenflächen abschwächend bzw. eine definierte Transmittanz aufweisend verspiegelt sind. WO 99/47852 n PCT/---.P99/00734The further glare-free weakening of said light part in said annular outer region can be achieved by weakening the inner surfaces or reflecting them with a defined transmittance. WO 99/47852 n PCT / ---. P99 / 00734
Insgesamt wird durch die erfindungsgemäße Ausbildung der Beleuchtungseinrichtung die gesamte verfügbare Lichtausbeute der Lichtquelle benutzt. Im Kernbereich, d.h., im besagten mittleren Bereich, wird zur Ausieuchtung der Fahrbahn, beispielsweise durch eine Linse, der Hauptlichtanteil dem Gegenverkehr abgewendet und auf die Fahrbahn zur Ausleuchtung gelenkt. Lediglich der äußere Bereich ist dem Gegenverkehr ungewandt und verwendet nur noch den Restlichtanteil, deren Intensitätsschwächung auch, wie bereits ausgeführt, durch eine metallische Teilbedampfung erreicht werden kann.Overall, the total available light output of the light source is used by the inventive design of the lighting device. In the core area, i.e. in the middle area, the main part of the light is turned away from oncoming traffic to illuminate the road, for example by means of a lens, and directed onto the road for illumination. Only the outer area is unresponsive to oncoming traffic and only uses the residual light component, the attenuation of its intensity, as already stated, can also be achieved by partial metal vapor deposition.
Somit entsteht auf sehr einfache Weise eine Aufteilung des Lichtes von der Lichtquelle derart, daß zum einen die Fahrbahn optimal und für den Gegenverkehr blendfrei, ausgeleuchtet wird und zum anderen, das dem Gegenverkehr zugewandte Signalbild der Beleuchtungseinrichtung blendfrei abgeschwächt ist.This results in a very simple way of dividing the light from the light source such that, on the one hand, the road is optimally illuminated and glare-free for oncoming traffic and, on the other hand, the signal image of the lighting device facing oncoming traffic is weakened without glare.
In vorteilhafter Ausgestaltung kann die Beieuchtungseinrichtung von Reflexionstyp sein, so daß hinter der Lichtquelle ein Reflektor angeordnet ist.In an advantageous embodiment, the illumination device can be of the reflection type, so that a reflector is arranged behind the light source.
Weitergehend kann der Reflektor zur Lichtquelle derart positioniert sein, daß die Kern- lichtrefiexion auf den mittleren Bereich der Lichtaustrittsfläche projizierbar ist, und die übrige Streulichtausbeute den äußeren Bereich beleuchtet.Furthermore, the reflector can be positioned in relation to the light source in such a way that the core light reflection can be projected onto the central area of the light exit surface, and the remaining scattered light yield illuminates the outer area.
Wie gesagt, kann der mittlere Bereich durch eine Linse gebildet werden, bzw. eine solche enthalten.As said, the central region can be formed by a lens or contain such a lens.
In besonders vorteilhafter Ausgestaltung ist der äußere Bereich derart verspiegelt, daß der besagte Streulichtanteil denselben von der Lichtquelle ausgehend durchscheinend durchleuchtet und bei von vorne kommendem Licht verspiegelt scheint.In a particularly advantageous embodiment, the outer region is mirrored in such a way that said scattered light component shines through it translucently starting from the light source and appears mirrored when the light comes from the front.
Die Erfindung ist in der Zeichnung dargestellt und nachfolgender näher beschrieben.The invention is illustrated in the drawing and described in more detail below.
Es zeigt:It shows:
Figur 1 : Schnitt durch eine erfindungsgemäße Beleuchtungseinrichtung.Figure 1: Section through a lighting device according to the invention.
Figur 2: Frontansicht. Figur 1 zeigt einen Schnitt durch einen erfindungsgemäß ausgestalteten Scheinwerfer. Derselbe ist innerhalb eines Lampengehäuses 30 angeordnet. Die wesentlichen Elemente sind die Lampe 1 , die zentriert in einem Reflektor 2 angeordnet ist. Dabei wird das von der Lampe 1 emittierte Licht über den Reflektor 2 im wesentlichen auf die davor angeordnete Linse 11 gerichtet. Die besagte Linse 11 ist im sogenannten erfindungsgemäßen mittleren Bereich der gesamten Lichtaustrittsfläche angeordnet. Die gesamte Lichtaustrittsfläche wird jedoch von der gesamten Abdeckung 21 realisiert, was in nachfolgend beschriebener erfindungsgemäßer Weise geschieht. Innerhalb des Lampengehäuses 30 ist jedoch nicht nur das vom Reflektor 2 auf die Linse 11 gerichtete Licht das gesamt verfügbare Licht, sondern innerhalb des Lampengehäuses 30 ist auch sogenanntes Restlicht vorhanden, welches aus dem Reflektor 2 nicht auf die Linse 11 gerichtet wird, sondern diffus innerhalb des Lampengehäuses 30 gestreut wird. In bekannten Beteuchtungseinrichtungen werden hierzu zwischen Reflektor und Linse zylinder-mantelförmige Elemente angeordnet, die dieses ausgekoppelte Licht wieder in den Strahiengang der Linse zurückführen. Dies ist jedoch bei dem erfindungsgemäßen Scheinwerfer bzw. bei der erfindungsgemäßen Beleuchtungseinrichtung anders realisiert. Das quasi vagabundierende Restlicht, welches innerhalb des Lampengehäuses 30 gestreut wird und von der Linse 11 zumindest nicht mehr direkt, d.h., auf den vorbestimmten Focus gebracht wird, soll ganz bewußt die teiiverspiegelte Ringfläche 22 der Abdeckung 21 erreichen.Figure 2: Front view. Figure 1 shows a section through a headlamp designed according to the invention. The same is arranged within a lamp housing 30. The essential elements are the lamp 1, which is arranged centered in a reflector 2. The light emitted by the lamp 1 is directed via the reflector 2 essentially onto the lens 11 arranged in front of it. Said lens 11 is arranged in the so-called central region according to the invention of the entire light exit surface. However, the entire light exit surface is realized by the entire cover 21, which is done in the manner according to the invention described below. Inside the lamp housing 30, however, not only the light directed from the reflector 2 onto the lens 11 is the total available light, but inside the lamp housing 30 there is also so-called residual light, which is not directed from the reflector 2 onto the lens 11, but diffusely within of the lamp housing 30 is scattered. In known illuminating devices, cylinder-jacket-shaped elements are arranged between the reflector and lens for this purpose, which lead this coupled-out light back into the beam path of the lens. However, this is implemented differently in the headlight according to the invention or in the lighting device according to the invention. The quasi-stray residual light, which is scattered within the lamp housing 30 and is at least no longer directly, ie brought to the predetermined focus, by the lens 11, should deliberately reach the partially mirrored ring surface 22 of the cover 21.
D.h., das Kernlicht des Reflektors 2 wird auf die Linse 11 projiziert, während dem das Streulicht auf die teiiverspiegelte Ringfläche 22 trifft. Die Teilverspiegelung ist dabei so vorgesehen, daß das im Lampengehäuse 30 vorhandene Restlicht durchaus die teiiverspiegelte Ringfläche 22 durchscheinen kann. Die Teilverspiegelung der Ringfläche 22 ist dabei so ausgelegt bzw. so zu verstehen, daß das im Lampengehäuse 30 vorhandene Restlicht die besagte verspiegelte Ringfläche durchdringen kann und lediglich ein wenig abgedämpft wird. Die besagte Verspiegelung in diesem Maße gibt jedoch in Frontansicht, d.h., von außerhalb des Lampengehäuses auf dasselbe bzw. die Abdeckung geblickt, einen Spiegeleffekt wieder, so daß man von außerhalb des Lampengehäuses nicht in dasselbe hineinsehen kann.That is, the core light of the reflector 2 is projected onto the lens 11, during which the scattered light strikes the partially mirrored ring surface 22. The partial mirroring is provided so that the residual light present in the lamp housing 30 can shine through the partially mirrored ring surface 22. The partial mirroring of the ring surface 22 is designed or understood in such a way that the residual light present in the lamp housing 30 can penetrate the said mirrored ring surface and is only slightly damped. The said mirroring to this extent, however, shows a mirror effect in a front view, i.e. looking at the same or the cover from outside the lamp housing, so that one cannot look into the same from outside the lamp housing.
Die Kontur 23 der Abdeckung 21 bildet lediglich einen Ring, in welchem entweder die Linse 11 eingelassen ist oder der einen Übergang vom übrigen Bereich der Abdeckung in den Linsenbereich beinhaltet. Die Linse 11 kann jedoch auch in die Abdeckung mit eingearbei- o tet werden, so daß Linse 11 und Abdeckung 21 einstückig sind. D.h., innerer Bereich 10 und äußerer Bereich 20 der Abdeckung 21 gehen dann stoffschlüssig ineinander über.The contour 23 of the cover 21 only forms a ring, in which either the lens 11 is embedded or which contains a transition from the remaining area of the cover into the lens area. However, the lens 11 can also be incorporated into the cover with o tet so that lens 11 and cover 21 are in one piece. That is, the inner region 10 and the outer region 20 of the cover 21 then merge into one another.
Abbildung 2 zeigt nur schematisch die Anordnung der Beleuchtungseinrichtung in einem Einbauschacht 40. Der Einbauschacht 40 kann sich dabei beispielsweise im Frontbereich des Kraftfahrzeuges beidseitig neben den Kühlerschlitzen befinden. Zu erkennen ist deutlich die Abgrenzung der eigentlichen Lampenabdeckung 21 im mittleren Bereich 10, der die Linse beinhaltet, sowie den erfindungsgemäßen äußeren Ringbereich 20. Der äußere Ringbereich 20 , d.h., die Fläche zwischen den beiden dargestellten dicken Kreislinien, ist dabei in der erfindungsgemäßen Weise verspiegelt. Dies bewirkt, daß das vom Reflektor 2 auf die Linse projizierte Kernlicht der Lampe durch den mittleren Bereich 10, d.h., die dahinter oder davor angeordnete Linse das Lampengehäuse verläßt. Dieser Lichtkegel dient zur Ausleuchtung der Fahrbahn und ist auf dieselbe gerichtet, d.h., aus dem Gegenverkehrsichtfeld abgeblendet. Durch die entsprechend verspiegelte Ringfläche 20 wird das Restlicht innerhalb des Lampengehäuses gedämpft nach außen emittiert. D.h., für den Gegenverkehr ergibt sich eine hell erleuchtete, abgeblendete mittlere Kreisfläche sowie eine mit einer zweiten effektiven Beleuchtungsstärke emittierende Kreisringfläche außerhalb. Der den mittleren Bereich verlassende Lichtkegel 10 ist dem Gegenverkehr abgeblendet, ist jedoch als deutlich hellere Kreisfläche erkennbar. Die äußere Ringfläche ist abgedämpft, so daß sich insgesamt ein Signalbild für den Gegenverkehr ergibt. D.h., alles Licht ist entsprechend aufgeteilt, der mittlere Bereich lediglich auf die Fahrbahn fokussiert, d.h., abgeblendet, und die Kreisringfläche als Signalbild dem Gegenverkehr in iichtgedämpfter Weise zugewandt.Figure 2 shows only schematically the arrangement of the lighting device in an installation slot 40. The installation slot 40 can be located, for example, in the front area of the motor vehicle on both sides next to the radiator slots. The delimitation of the actual lamp cover 21 in the central region 10, which contains the lens, and the outer ring region 20 according to the invention can be clearly seen. The outer ring region 20, ie the area between the two thick circular lines shown, is mirrored in the manner according to the invention . This causes the core light of the lamp projected onto the lens by the reflector 2 through the central region 10, i.e. the lens arranged behind or in front of it, to leave the lamp housing. This cone of light is used to illuminate the road and is directed towards it, i.e., dimmed from the oncoming traffic field of vision. Due to the correspondingly mirrored ring surface 20, the residual light within the lamp housing is emitted to the outside in an attenuated manner. This means that for oncoming traffic there is a brightly lit, dimmed central circular area and a circular ring area outside with a second effective illuminance. The light cone 10 leaving the central area is dimmed from oncoming traffic, but is recognizable as a clearly brighter circular area. The outer ring surface is damped, so that overall there is a signal image for oncoming traffic. This means that all light is divided accordingly, the central area is only focused on the road, i.e., dimmed, and the circular ring surface as a signal image faces the oncoming traffic in an unattenuated manner.
Dadurch wird die besagte Funktion erzielt, daß Kernreflexionslicht zum Ausleuchten der Fahrbahn zu verwenden und das übrige Licht zur blendfreien Signalbildung.This achieves the function mentioned that core reflection light is used to illuminate the road and the rest of the light for glare-free signal formation.
Des weiteren ist zu erkennen, daß Stege 11 in der Kontur der Abdeckung angeordnet sind, die lediglich zur Befestigung des in Figur 1 dargestellten Kreisringes 23 zur Aufnahme der Linse 11 dienen. Die Darstellung der Stege 11 ist lediglich schematisch und bedarf im übrigen hier keiner weiteren Ausführung. Furthermore, it can be seen that webs 11 are arranged in the contour of the cover, which are used only for fastening the circular ring 23 shown in FIG. 1 for receiving the lens 11. The representation of the webs 11 is only schematic and otherwise requires no further execution.
