Description

Die Erfindung bezieht sich auf ein Scheinwerfermodul für ein Fahrzeug nach dem Oberbegriff von Anspruch 1.The invention relates to a headlight module for a vehicle according to the preamble of claim 1.

Danach ist ein Scheinwerfermodul für ein Fahrzeug bekannt, mit einer Lichtaustrittsscheibe, die zur Anpassung an eine angrenzende Außenkontur des Fahrzeugs dreidimensional gekrümmt ist, einer Leuchtdiodenanordnung und einer planaren Grundplatine zur Stromversorgung und Fixierung der einzelnen Leuchtdioden der Leuchtdiodenanordnung.According to this, a headlight module for a vehicle is known, with a light exit disk that is three-dimensionally curved to adapt to an adjacent outer contour of the vehicle, a light-emitting diode arrangement and a planar base board for power supply and fixing of the individual light-emitting diodes of the light-emitting diode arrangement.

Insbesondere an Frontscheinwerfern im Schienenfahrzeugbau werden besondere Anforderungen hinsichtlich ihrer Leuchtstärke, Lichtverteilung, Sichtbarkeit unter bestimmten Stellungen des Fahrzeugs im Gleisbett, Einstellbarkeit und Zugänglichkeit gestellt. Viele diese Anforderungen sind in speziellen Schienenfahrzeugnormen festgehalten, so z.B. in der TSI- und der UIC-Norm, was den europäischen Raum anbetrifft, der Ghost für Russland und der NPRM2 für den amerikanischen Markt.In particular, front headlights in rail vehicle construction are subject to special requirements with regard to their luminosity, light distribution, visibility under certain positions of the vehicle on the track bed, adjustability and accessibility. Many of these requirements are laid down in special rail vehicle standards, e.g. in the TSI and UIC standards for Europe, the Ghost for Russia and the NPRM2 for the American market.

Da als Frontscheinwerfer eingesetzte Scheinwerfermodule regelmäßig an eine angrenzende Kontur des damit zu bestückenden Fahrzeugs anzupassen sind, ist es schwierig, Scheinwerfermodule zu realisieren, die bei einer Vielzahl von Fahrzeugkopfkonturen einsetzbar sind. Es ist bekannt, Standard-LED-Scheinwerfermodule einzusetzen. Bei diesen ergibt sich jedoch der Nachteil, dass bei größeren Winkeln zwischen den Ausrichtungen der Lichtaustrittsscheibe und der planaren Grundplatine erhebliche Abstände zwischen den Leuchtdioden und der Lichtaustrittsscheibe vorkommen können. Wünschenswert wäre eine Anordnung der Leuchtdioden unmittelbar benachbart zu einer Innenseite der Lichtaustrittsscheibe. Des Weiteren ist es bekannt, nicht eine einzelne planare Grundplatine einzusetzen, sondern treppenförmig kaskadierte Einzelplatinen mit vergleichsweise kleineren Leuchtdiodenmodulreihen. Bei dieser Ausführung können zwar einzelne Leuchtdioden näher an die Lichtaustrittsscheibe herangebracht werden. Es ergeben sich jedoch Nachteile dahingehend, dass eine einheitliche Einstellung bzw. Justierung der Scheinwerfermodule nicht mehr bzw. nur erschwert möglich ist. Bei einer kaskadierten Lösung müssten nämlich sämtliche Einzelplatinen separat justiert und zueinander ausgerichtet werden. Dies hat erhebliche Montagekosten zur Folge.Since headlight modules used as headlights have to be regularly adapted to an adjacent contour of the vehicle to be fitted with them, it is difficult to implement headlight modules that can be used with a large number of vehicle head contours. It is known to use standard LED headlight modules. With these, however, there is the disadvantage that with larger angles between the orientations of the light exit disk and the planar base plate, considerable distances can occur between the light-emitting diodes and the light exit disk. An arrangement of the light-emitting diodes directly adjacent to an inside of the light-emitting pane would be desirable. Furthermore, it is known not to use a single planar base board, but to use individual boards cascaded in the form of steps with comparatively smaller rows of light-emitting diode modules. At this Although individual light-emitting diodes can be brought closer to the light-emitting disk in execution. However, there are disadvantages in that a uniform setting or adjustment of the headlight modules is no longer possible or only possible with difficulty. In a cascaded solution, all the individual boards would have to be adjusted separately and aligned with one another. This results in considerable installation costs.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein Scheinwerfermodul der eingangs genannten Art derart weiterzuentwickeln, dass eine Positionierung und eine Einstellbarkeit eines Lichtaustritts für die Leuchtdiodenanordnung hinter der Lichtaustrittsscheibe verbessert und vereinfacht wird.Proceeding from this, the invention is based on the object of further developing a headlight module of the type mentioned at the outset in such a way that positioning and adjustability of a light exit for the light-emitting diode arrangement behind the light exit disk is improved and simplified.

Diese Aufgabe wird gelöst durch ein Scheinwerfermodul nach Anspruch 1.This object is achieved by a headlight module according to claim 1.

Danach zeichnet sich das eingangs beschriebene Scheinwerfermodul dadurch aus, dass der Lichtaustrittsscheibe auf ihrer Innenseite unmittelbar benachbart eine Lichtausgabeanordnung vorgesehen ist, die aus einzelnen Lichtausgabeelementen aufgebaut ist, die jeweils einer der Leuchtdioden der Leuchtdiodenanordnung zugeordnet und in ihrem Abstand zu der Lichtaustrittsscheibe derart einstellbar sind, dass sie einer Kontur einer Innenseite der Lichtaustrittsscheibe folgen, und an der Grundplatine (direkt oder indirekt) befestigt sind.Accordingly, the headlight module described at the beginning is characterized in that a light output arrangement is provided immediately adjacent to the light exit disk on its inside, which is made up of individual light output elements which are each assigned to one of the light-emitting diodes of the light-emitting diode arrangement and whose distance from the light exit disk can be adjusted in such a way that they follow a contour of an inside of the light exit disk, and are attached to the base board (directly or indirectly).

Im Ergebnis wird sozusagen eine "Einzelkaskadierung" der einzelnen Lichtausgabeelemente realisiert. Durch eine flexible Einstellbarkeit des Abstands der Lichtausgabeelemente zur Innenseite der Austrittsscheibe lässt sich eine Lichtausgabe unmittelbar benachbart zur Innenseite der Lichtaustrittsscheibe erreichen.As a result, a so-to-speak “individual cascading” of the individual light output elements is realized. The flexible adjustability of the distance between the light output elements and the inside of the exit pane allows light to be output directly adjacent to the inside of the light exit pane.

Im Sinne der vorliegenden Beschreibung wird unter einer "Lichtausgabeanordnung" eine räumliche Anordnung von Lichtquellen verstanden, wie sie von außerhalb des Scheinwerfermoduls wahrnehmbar ist. Beispielsweise können die einzelnen Lichtausgabeelemente von den Leuchtioden der Leuchtdiodenanordnung selbst gebildet sein, wobei dann die Leuchtdioden in ihrem Abstand justierbar unmittelbar benachbart zur Innenseite der Lichtaustrittsscheibe positioniert werden. Es ist jedoch ebenso möglich, dass die Leuchtdioden unmittelbar auf der planaren Grundplatine angeordnet sind, ihr emittiertes Licht jedoch über einen geeigneten Lichtleiter mit einer endseitigen Lichtaustrittsfläche unmittelbar auf die Innenseite der Lichtaustrittsscheibe geführt wird. In beiden Fällen würde eine Positionierung der Leuchtdioden bzw. der freien Enden der Lichtleiter gegenüber der Innenseite der Lichtaustrittsscheibe über eine Einstellvorrichtung erfolgen, die an der planaren Grundplatine des Scheinwerfermoduls befestigt ist.As used herein, a "light output array" is a spatial array of light sources understood as perceptible from outside the headlight module. For example, the individual light output elements can be formed by the light-emitting diodes of the light-emitting diode arrangement itself, the light-emitting diodes then being positioned directly adjacent to the inside of the light-emitting pane so that their distance can be adjusted. However, it is also possible for the light-emitting diodes to be arranged directly on the planar base plate, but for their emitted light to be guided directly to the inside of the light-emitting pane via a suitable light guide with a light-emitting surface at the end. In both cases, the light-emitting diodes or the free ends of the light guides would be positioned opposite the inside of the light-emitting pane via an adjustment device that is attached to the planar base board of the headlight module.

In einer bevorzugten Ausführungsform sind die Lichtausgabeelemente jeweils von Lichtaustrittsflächen freier Enden einzelner längeneinstellbarer Röhrchen gebildet, die jeweils an der Grundplatine angebracht sind und in denen jeweils eine Leuchtdiode angeordnet ist. Je nachdem, ob die Leuchtdioden unmittelbar an den freien Enden der Röhrchen oder auf der Grundplatine angeordnet sind, wirken die Röhrchen damit als reine Justiereinrichtung für deren Positionierung (die Lichtaustrittsflächen erscheinen als Lichtausgabeelemente) oder als Kombination aus einer Positioniereinrichtung und bevorzugt einem Lichtleiter oder röhrenförmigen Lichtreflektor. Grundsätzlich können die Leuchtdioden an beliebiger Stelle entlang der längeneinstellbaren Röhrchen in deren Innenraum fixiert sein und ggf. ist den jeweiligen Röhrchen eine Linse vorgeschaltet.In a preferred embodiment, the light output elements are each formed by light exit surfaces of free ends of individual length-adjustable tubes, which are each attached to the base board and in each of which a light-emitting diode is arranged. Depending on whether the light-emitting diodes are arranged directly on the free ends of the tubes or on the base plate, the tubes act purely as an adjustment device for their positioning (the light exit surfaces appear as light output elements) or as a combination of a positioning device and preferably a light guide or tubular light reflector . In principle, the light-emitting diodes can be fixed at any point along the length-adjustable tubes in their interior and, if necessary, a lens is connected in front of the respective tubes.

Vorteilhafterweise sind die Röhrchen aus wenigstens zwei Längsabschnitten gebildet, von denen ein erster Längsabschnitt auf der Grundplatine angebracht und ein zweiter Längsabschnitt längeneinstellbar mit dem ersten Längenabschnitt verbunden ist. Dabei können die ersten Längenabschnitte als Gewindebuchsen einheitlicher Länge und die zweiten Längsabschnitte als Gewinderöhrchen variabler Länge ausgebildet sein. Eine Längserstreckung der Gewindebuchsen bestimmt damit ein Längenintervall, innerhalb dessen die zweiten Längsabschnitte relativ zu der (planaren) Grundplatine und der Lichtaustrittsscheibe frei positionierbar sind. Alternativ können die Längsabschnitte auch nur relativ zueinander verschieblich und z. B. mittels einer Madenschraube gegeneinander fixiert sein.The tubes are advantageously formed from at least two longitudinal sections, of which a first longitudinal section is attached to the base plate and a second longitudinal section is connected to the first longitudinal section in a length-adjustable manner. The first length sections as threaded bushings of uniform length and the second Longitudinal sections can be designed as threaded tubes of variable length. A longitudinal extent of the threaded bushings thus determines a length interval within which the second longitudinal sections can be freely positioned relative to the (planar) base plate and the light exit panel. Alternatively, the longitudinal sections can only be displaced relative to one another and z. B. be fixed against each other by means of a grub screw.

In einer bevorzugten Variante sind die Leuchtdioden unmittelbar auf der Grundplatine angeordnet. In diesem Fall kann die Röhrchenanordnung zur Minimierung von Lichtverlusten an ihrer Innenseite verspiegelt sein, so dass das von der einzelnen Leuchtdiode emittierte Licht möglichst verlustfrei zur Austrittsfläche am freien Ende des Röhrchens transportiert wird.In a preferred variant, the light-emitting diodes are arranged directly on the motherboard. In this case, the tube arrangement can be mirrored on its inside to minimize light losses, so that the light emitted by the individual light-emitting diode is transported with as little loss as possible to the exit surface at the free end of the tube.

In einer alternativen Ausführungsform können die Leuchtdioden in den freien Enden der Röhrchen angeordnet sein und für jede Leuchtdiode kann eine Energieversorgungsleitung vorgesehen sein, welche die Leuchtdiode mit der Grundplatine verbindet. Bei dieser Ausführungsform entfällt die Funktion der Röhrchen als Lichtleiter.In an alternative embodiment, the light-emitting diodes can be arranged in the free ends of the tubes and a power supply line can be provided for each light-emitting diode, which connects the light-emitting diode to the motherboard. In this embodiment, the tube does not function as a light guide.

Zur variablen Positionierbarkeit der Leuchtdioden ist es von Vorteil, wenn die jeweils zugeordnete Energieversorgungsleitung spiralförmig ausgebildet ist, um Abstandsänderungen zur planaren Grundplatine zu gestatten. Aber auch andere Formen einer flexiblen Energieversorgung z.B. über Schleifkontakte innerhalb der Röhrchen sind denkbar.In order to be able to position the light-emitting diodes variably, it is advantageous if the power supply line assigned in each case is designed in a spiral shape in order to allow changes in the distance to the planar motherboard. But other forms of flexible energy supply, e.g. via sliding contacts inside the tubes, are also conceivable.

Die Lichtlichtausgabeelemente, insbesondere die Lichtaustrittsflächen der freien Enden der einzelnen Längeneinstellbaren Röhrchen, können zusätzlich mittels eines Traggerüstes positioniert sein. Dieses Traggerüst kann beispielsweise geeignete Haltevorrichtungen für die einzelnen Röhrchen umfassen. Es ist auch möglich, dass die Lichtausgabeelemente bzw. die Lichtausgabeelemente aufweisenden Röhrchen zusätzlich mittels einer Lochplatte und/oder einer Abdeckplatte geführt werden, um eine stabile Lagerung der Röhrchen und damit auch eine Stabilisierung eines vorgesehen Lichtausgaberasters der Lichtausgabeelemente sicherzustellen.The light output elements, in particular the light exit surfaces of the free ends of the individual length-adjustable tubes, can also be positioned by means of a supporting structure. This support structure can, for example, include suitable holding devices for the individual tubes. It is also possible that the light output elements or the tubes having the light output elements are additionally guided by means of a perforated plate and/or a cover plate be in order to ensure a stable storage of the tubes and thus also a stabilization of an intended light output grid of the light output elements.

Figur 1 zeigt ein Scheinwerfermodul für ein Schienenfahrzeug, mit einer planaren Grundplatine 1, die eine Leuchtdiodenanordnung trägt, welche aus einzelnen Leuchtdioden 2 gebildet ist, von denen, wie auch bei weiteren, noch zu erläuternden Komponenten des Scheinwerfermoduls, aus Übersichtlichkeitsgründen lediglich eine mit einem Bezugszeichen bezeichnet ist. Die Leuchtdioden 2 sind in mehreren Reihen übereinander auf der Grundplatine 1 angeordnet, wobei die einzelnen Reihen räumlich zueinander versetzt sind. Ein erster Längsabschnitt 4 eines längeneinstellbaren Röhrchens 3 wird von einer Gewindebuchse gebildet, die über ihre gesamte Länge mit einem Innengewinde ausgestattet ist. Die Gewindebuchsen sind in fertig montiertem Zustand, vergleich Figur 2, auf der Grundplatine 1 befestigt und senkrecht zur Grundplatine 1 und damit parallel zu einer Haupt-Lichtaustrittsrichtung des Scheinwerfermoduls angeordnet. figure 1 shows a headlight module for a rail vehicle, with a planar base board 1, which carries a light-emitting diode arrangement, which is formed from individual light-emitting diodes 2, of which, as with other components of the headlight module that are still to be explained, only one is designated with a reference symbol for reasons of clarity . The light-emitting diodes 2 are arranged in several rows one above the other on the motherboard 1, with the individual rows being spatially offset from one another. A first longitudinal section 4 of a length-adjustable tube 3 is formed by a threaded bushing which is equipped with an internal thread over its entire length. The threaded bushes are in fully assembled condition, compare figure 2 , Fixed on the motherboard 1 and perpendicular to the motherboard 1 and thus arranged parallel to a main light exit direction of the headlight module.

Eine Lochplatte 5, die mit Durchgangsbohrungen 6 versehen ist, ist unmittelbar auf der der Grundplatine 1 abgewandten Seite der Gewindebuchsen aufgesetzt. Zweite, jeweils als Gewinderöhrchen ausgeführte Längsabschnitte 7 der Röhrchen 3 sind an ihrem der Grundplatine 1 zugewandten Ende mit einem Außengewinde ausgestattet, so dass sich die zweiten Längsabschnitte 7 der Röhrchen 3 in die zugeordneten Innengewinde der ersten Längsabschnitte 4 einschrauben lassen. In dieser Weise ergibt sich eine Längenverstellbarkeit der Röhrchen 3 insgesamt, deren Längengrenzen durch eine gewählte Längserstreckung der Gewindebuchsen bestimmt ist.A perforated plate 5, which is provided with through-holes 6, is placed directly on the side of the threaded bushings facing away from the base plate 1. Second longitudinal sections 7 of the tubes 3, each designed as a threaded tube, are equipped with an external thread at their end facing the base plate 1, so that the second longitudinal sections 7 of the tubes 3 can be screwed into the associated internal threads of the first longitudinal sections 4. In this way, the tubes 3 can be adjusted in length overall, the length limits of which are determined by a selected longitudinal extension of the threaded bushings.

Die zweiten Längsabschnitte 7 der Röhrchen 3 durchdringen die Durchgangsbohrungen 6 der Lochplatte 5, so dass die Lochplatte 5 relative Abstände der einzelnen Röhrchen 3 untereinander festlegt und die Röhrchenanordnung insgesamt stabilisiert.The second longitudinal sections 7 of the tubes 3 penetrate the through bores 6 of the perforated plate 5, so that the perforated plate 5 defines relative distances between the individual tubes 3 and stabilizes the tube arrangement overall.

Des Weiteren ist jedem der Röhrchen 3 eine Linse 8 zugeordnet, welche jeweils das von der zugeordneten Leuchtdiode 2 emittierte Licht bündelt.Furthermore, each of the tubes 3 is assigned a lens 8 which bundles the light emitted by the assigned light-emitting diode 2 .

Eine Abdeckplatte 9 ist mit Durchgangsbohrungen 10 versehen. Wie aus Figur 2 hervorgeht, wird die Abdeckplatte 9, die auch Designzwecken dient, auf die von den Röhrchen 3 gebildete Röhrchenanordnung gesteckt, so dass jedes der Röhrchen 3 eine der Durchgangsbohrungen 10 durchdringt. Die Abdeckplatte 9 stabilisiert somit zusätzlich die Röhrchenanordnung und weist zudem stegförmige Seperatoren auf, die übereinander liegende Reihen von Röhrchen 3 optisch voneinander trennen. Wie Figur 2 veranschaulicht, ist die äußere Form der Abdeckplatte 9 an diejenige einer Lichtaustrittsscheibe 11 im Sinne eines Flächen-Offsets angepasst, d.h. einander zugewandte Außenflächen der Abdeckplatte 9 und der Lichtaustrittsscheibe 11 halten einen einheitlichen Abstand zueinander ein. Es ist ersichtlich, dass freie Enden 12 der zweiten Längsabschnitte 7 der Röhrchen 3 unmittelbar an einer Innenseite der Lichtaustrittsscheibe 11 angeordnet sind. Lichtaustrittsflächen 13 der freien Enden 12 wirken als Lichtausgabeelemente des Scheinwerfermoduls, d.h. bei Betrachtung von außen werden die Lichtaustrittsflächen 13 als Orte der Lichtquellen wahrgenommen. Dies gilt unabhängig davon, an welchem Ort entlang der Röhrchen 3 eine zugeordnete Leuchtdiode 2 tatsächlich angeordnet ist.A cover plate 9 is provided with through holes 10 . How out figure 2 shows, the cover plate 9, which also serves design purposes, is placed on the tube arrangement formed by the tubes 3, so that each of the tubes 3 penetrates one of the through-holes 10. The cover plate 9 thus additionally stabilizes the tube arrangement and also has bar-shaped separators which optically separate rows of tubes 3 lying one above the other. How figure 2 illustrated, the outer shape of the cover plate 9 is adapted to that of a light exit panel 11 in the sense of a surface offset, ie facing outer surfaces of the cover plate 9 and the light exit panel 11 maintain a uniform distance from one another. It can be seen that free ends 12 of the second longitudinal sections 7 of Tubes 3 are arranged directly on an inside of the light exit disk 11 . Light exit surfaces 13 of the free ends 12 act as light output elements of the headlight module, ie when viewed from the outside, the light exit surfaces 13 are perceived as the locations of the light sources. This applies regardless of the location along the tubes 3 at which an associated light-emitting diode 2 is actually arranged.

Figur 3 zeigt eine Unterbaugruppe des Scheinwerfermoduls von Figur 1. Diese Unterbaugruppe umfasst die Grundplatine 1, die Röhrchen 3 sowie die Lochplatte 5. Seitlich der Röhrchen 3 ist ein Traggerüst 14 vorgesehen, das sich schräg entlang den Röhrchen 3 erstreckt. Das Traggerüst 14 trägt Abstandshalter 15, welche in einer gemeinsamen Ebene liegende Röhrchen 3 jeweils wenigstens teilweise umschließen, so dass diese präzise positioniert sind. Zudem ist aus Figur 3 ersichtlich, dass die Gewindebuchsen 4 von einheitlicher Längenausdehnung sind, während die Röhrchen 3 je nach Anordnung der Lichtaustrittsscheibe 13 im Raum auch von variabler Länge sein können. Für jedes der Röhrchen 3 ist jedoch die Längeneinstellbarkeit gegeben, und zwar durch Einschrauben der zweiten Längenabschnitte 7 der Röhrchen 3 in die als Gewindebuchsen vorliegenden ersten Längsabschnitte 4. figure 3 12 shows a subassembly of the headlight module of FIG figure 1 . This sub-assembly comprises the base board 1, the tubes 3 and the perforated plate 5. A support frame 14 is provided on the side of the tubes 3, which extends obliquely along the tubes 3. The support framework 14 carries spacers 15, which each at least partially enclose small tubes 3 lying in a common plane, so that these are precisely positioned. In addition, it is off figure 3 It can be seen that the threaded bushings 4 are of uniform length, while the tubes 3 can also be of variable length depending on the arrangement of the light exit disc 13 in space. However, the length of each tube 3 can be adjusted by screwing the second longitudinal sections 7 of the tubes 3 into the first longitudinal sections 4 present as threaded bushings.

Die Figuren 4 und 5 zeigen verschiedene Ausführungsformen, die sich ausschließlich durch die Position der Leuchtdioden 2 in Längsrichtung der Röhrchen 3 nebst zugehöriger Linse 8 unterscheiden. Bei der Ausführungsform nach Figur 4 sind die Leuchtdioden 2 unmittelbar auf der Grundplatine 1 angeordnet, wobei sich ihre jeweils zugeordnete Linse 8 unmittelbar auf der der Grundplatine 1 abgewandten Seite der Leuchtdiode 2 befindet. Die Röhrchen 3 sind innen verspiegelt, so dass sie als Lichtleiter bzw. als rohrförmiger Reflektor für das von den Leuchtdioden 2 emittierte Licht wirken. Alternativ kann auch eine Ausführung als Faser-Lichtleiter vorgesehen werden. Auch in diesem Fall erscheint von außen die Lichtaustrittsfläche 13 des freien Endes 12 des betreffenden Röhrchens 3 als Lichtquelle. Alternativ könnte die Linse 8 auch am entgegengesetzten Ende der einstellbaren Röhrchen 3 platziert werden und dort das Licht noch einmal bündeln.The figures 4 and 5 show different embodiments, which differ only by the position of the light-emitting diodes 2 in the longitudinal direction of the tube 3 together with the associated lens 8. In the embodiment according to figure 4 the light-emitting diodes 2 are arranged directly on the base board 1, with their associated lens 8 being located directly on the side of the light-emitting diode 2 facing away from the base board 1. The tubes 3 are mirrored on the inside, so that they act as light guides or as tubular reflectors for the light emitted by the light-emitting diodes 2 . Alternatively, an embodiment as a fiber optic light guide can also be provided. In this case, too, the light exit surface 13 of the free end 12 of the relevant tube 3 appears from the outside as a light source. Alternatively, the lens 8 could also be placed at the opposite end of the adjustable tube 3 and focus the light there again.

Bei der in Figur 5 veranschaulichten Ausführungsform ist die jeweilige Linse 8 unmittelbar an der jeweiligen Austrittsfläche 13 des betreffenden Röhrchens 3 angeordnet. Bezogen auf das jeweilige Röhrchen 3 liegt die jeweils zugeordnete Leuchtdiode 2 einwärts der Linse 13. Jeweilige Leuchtdioden 2 und zugehörige Linsen 8 sind in inneren Hohlräumen der Röhrchen 3 befestigt. Zur Energieversorgung der einzelnen Leuchtdioden 2 ist jeweils eine Energieversorgungsleitung 16 vorgesehen, welche die jeweilige Leuchtdiode 2 mit der Grundplatine 1 elektrisch verbindet. Zur Unterstützung einer Längenjustierung der einzelnen Röhrchen 3 ist die Energieversorgungsleitung 16 spiralförmig ausgebildet oder über Schleifkontakt im Röhrchen sichergestellt. Die Röhrchen 3 dienen bei dieser Ausführungsform allein als längeneinstellbarer Abstandshalter für Leuchtdioden-Linsen-Kombinationen, wobei in indirekter Weise wiederum eine Fixierung an der Grundplatine 1 gegeben ist.At the in figure 5 In the illustrated embodiment, the respective lens 8 is arranged directly on the respective exit surface 13 of the tube 3 in question. In relation to the respective tube 3, the associated light-emitting diode 2 is located inwards of the lens 13. The respective light-emitting diodes 2 and associated lenses 8 are fastened in inner cavities of the tubes 3. To supply energy to the individual light-emitting diodes 2 , a power supply line 16 is provided in each case, which electrically connects the respective light-emitting diode 2 to the motherboard 1 . To support length adjustment of the individual tubes 3, the energy supply line 16 is designed in a spiral shape or is secured in the tube by means of a sliding contact. In this embodiment, the tubes 3 serve solely as length-adjustable spacers for light-emitting diode-lens combinations, with in turn being fixed to the base plate 1 in an indirect manner.

In einer nicht dargestellten Ausführungsform ist es ebenfalls denkbar, die die Leuchtdioden auf die freien Enden 12 der Röhrchen 3 aufgesetzt sind. In diesem Fall wirken die Leuchtdioden 2 selbst als Lichtausgabeelemente, wobei auf Linsen verzichtet werden kann.In an embodiment that is not shown, it is also conceivable that the light-emitting diodes are placed on the free ends 12 of the tubes 3 . In this case, the light-emitting diodes 2 themselves act as light-emitting elements, and lenses can be dispensed with.
