Description

Die Erfindung betrifft eine Leuchte mit einem Lampengehäuse, das mindestens ein Leuchtmittel kapselt, und mit einem am Lampengehäuse anschließenden Verbindungsmittel, das zum Lagern der Leuchte über einem Schienenfuß und auf Höhe eines Schienenstegs einer Schiene eines Bahngleises ausgebildet ist.The invention relates to a luminaire having a lamp housing which encapsulates at least one luminous means, and having a connecting means which adjoins the lamp housing and which is designed to mount the luminaire over a rail foot and at the level of a rail web of a railroad track.

Zur verbesserten Ausleuchtung eines Bahngleises schlägt die WO2008/107141A1 vor, an einem Schienensteg einer Schiene eines Bahngleises eine Leuchte mit LED-Leuchtmitteln zu befestigen. Die Leuchten sind in einem Gehäuse gekapselt untergebracht, das über eine Verklebung oder eine Verschraubung als Verbindungsmittel mit am Schienensteg der Schiene befestigt ist. Dadurch wird die Leuchte über einem Schienenfuß der Schiene und auf Höhe des Schienenstegs gelagert. Nachteilig übertragen sich durch eine derartige Befestigung Erschütterungen der Schiene unmittelbar auf die Leuchte, was diese beschädigen oder auch von der Schiene lösen kann. Es ist sohin eine verminderte Standfestigkeit der Leuchte zu befürchten.For improved illumination of a railway track suggests the WO2008 / 107141A1 to attach a luminaire with LED bulbs to a rail web of a railway track rail. The lights are housed encapsulated in a housing which is secured via a bond or a screw connection means as with the rail web of the rail. As a result, the lamp is mounted above a rail of the rail and at the level of the rail web. Disadvantageously transferred by such a mounting vibrations of the rail directly on the lamp, which can damage this or even solve the rail. It is thus to fear a reduced stability of the lamp.

Es ist daher die Aufgabe der Erfindung, eine Leuchte der eingangs geschilderten Art derart konstruktiv zu verändern, dass diese trotz Befestigung an einer Schiene eine hohe Standfestigkeit aufweist. Zudem soll die Leuchte konstruktiv einfach ausgeführt und in ihrer Handhabung einfach sein.It is therefore an object of the invention to change a luminaire of the type described constructively such that it has a high stability despite attachment to a rail. In addition, the light should be structurally simple and easy to handle.

Die Erfindung löst die gestellte Aufgabe dadurch, dass das von einem federnden Material ausgebildete Verbindungsmittel eine Klammer und einen Endabschnitt aufweist, wobei die Klammer einen zum Untergreifen des Schienenfußes ausgebildeten Unterzug und zwei zum Umgreifen von gegenüberliegenden Schmalseiten des Schienenfußes ausgebildete Laschen aufweist, welche Laschen an beiden Enden des Unterzugs anschließen, und wobei das Lampengehäuse am Endabschnitt befestigt ist, der an einer Lasche der Klammer und zu dieser Lasche nach außen abgewinkelt anschließt, um das Lampengehäuse über dem Schienenfuß auf Höhe des Schienenstegs der Schiene federnd zu lagern.The invention achieves the stated object in that the connection means formed by a resilient material comprises a clamp and an end portion, wherein the clamp has a trained for engaging underneath the rail base beam and two trained to encompass opposite narrow sides of the rail foot plates, which tabs on both Connecting ends of the beam, and wherein the lamp housing is attached to the end portion, which at a tab of the clip and to this tab to the outside Angled adjoins to store the lamp housing over the rail foot at the height of the rail web of the rail resiliently.

Weist das von einem federnden Material ausgebildete Verbindungsmittel eine Klammer auf, wobei die Klammer einen zum Untergreifen des Schienenfußes ausgebildeten Unterzug und zwei zum Umgreifen von gegenüberliegenden Schmalseiten des Schienenfußes ausgebildete Laschen aufweist, welche Laschen an beiden Enden des Unterzugs anschließen, kann zunächst möglich werden, die Leuchte handhabungsfreundlich an einer Schiene zu befestigen. Aufgrund des federnden Materials kann die Klammer nämlich aufgebogen und damit leicht und sicher am Schienenfuß vorgesehen werden. Zudem können durch das federnde Material Toleranzen am Schienenfuß ausgeglichen werden - was die, insbesondere lösbare, Verbindung mit der Schiene verbessern kann.
Weist zudem das von einem federnden Material ausgebildete Verbindungsmittel einen Endabschnitt auf, wobei das Lampengehäuse am Endabschnitt befestigt ist, der an einer Lasche der Klammer und zu dieser Lasche nach außen abgewinkelt anschließt, kann zudem möglich werden, das Lampengehäuse direkt über dem Schienenfuß auf Höhe des Schienenstegs der Schiene federnd zu lagern. Es ist dadurch möglich, Erschütterungen der Schiene von der federnden Lagerung abzutragen, bevor diese das Lampengehäuse erreichen - womit sich die Gefahr der Beschädigung am oder des Lösens des Lampengehäuses vermindern kann. Eine besonders standfeste Leuchte ist damit geschaffen, die selbst widrigen Umständen am Bahngleis standhalten kann.
Des Weiteren ist die Ausführung des Verbindungsmittels unter Verwendung eines federnden Materials vergleichsweise einfach auszubilden, was die Lampe konstruktiv einfach und kostengünstig in der Herstellung machen kann. Im Allgemeinen wird erwähnt, dass sich als federndes Material ein federndes Flachmaterial besonders eignen kann.If the connecting means formed by a resilient material has a clamp, wherein the clamp has a lower rail designed to engage under the rail foot and two straps designed to encompass opposite narrow sides of the rail foot, which straps connect at both ends of the lower rail, it may initially be possible to do so Light to handle easy to attach to a rail. Because of the resilient material, the clip can namely bent and thus be easily and safely provided on the rail. In addition, tolerances on the rail foot can be compensated by the resilient material - which can improve the, in particular releasable, connection to the rail.
In addition, the connection means formed by a resilient material on an end portion, wherein the lamp housing is attached to the end portion which adjoins a tab of the clip and to this tab angled outward, can also be possible, the lamp housing directly above the rail at the height of the Rail track of the rail to store springy. It is thereby possible to remove vibrations of the rail from the resilient mounting before they reach the lamp housing - thus reducing the risk of damage to or loosening of the lamp housing. A particularly stable light is thus created, which can withstand adverse conditions on the railway track.
Furthermore, the design of the connecting means using a resilient material is relatively simple form, which can make the lamp structurally simple and inexpensive to manufacture. In general, it is mentioned that a springy material can be particularly suitable as a resilient material.

Ist das Lampengehäuse mit seiner Gehäuseunterseite am Endabschnitt befestigt, kann mit einer vergleichsweise breiten Überlappung zwischen diesen eine standfeste Verbindung zur Verfügung gestellt werden. Ein unbeabsichtigtes Lösen der festen Verbindung zwischen Lampengehäuse und Verbindungsmittel bzw. Klammer und Endabschnitt, ist damit verbessert zu vermeiden.If the lamp housing is fastened with its lower side of the housing at the end portion, can with a comparatively wide overlap between these a stable Connection can be provided. An unintentional release of the fixed connection between the lamp housing and connecting means or clamp and end portion, is thus to be avoided.

Schräge Flächen zur Abweisung von Flüssigkeiten können auf konstruktiv einfache Weise an der Leuchte geschaffen werden, wenn das Lampengehäuse im Querschnitt eine Parallelogrammform aufweist.Sloping surfaces for rejection of liquids can be created in a structurally simple manner on the lamp when the lamp housing has a parallelogram shape in cross section.

Indem das Lampengehäuse an seiner Gehäuserückseite ein davon abstehendes elektrisches Kabel aufweist, kann das elektrische Kabel bzw. damit auch die elektrische Verbindung der Lampe gegenüber mechanischen Beschädigungen besonders gut geschützt werden.By the lamp housing has on its rear side of a housing projecting electrical cable, the electrical cable or thus the electrical connection of the lamp against mechanical damage can be protected very well.

Springt zumindest die Gehäuseoberseite der Gehäuserückseite des Lampengehäuses vor, kann auf konstruktiv einfache Weise eine Abdeckung am Lampengehäuse ausgebildet werden. Diese Abdeckung kann gegebenenfalls ein elektrisches Kabel, einen elektrischen Anschluss, elektrischen Stecker/Buchse und/oder auch eine Kabeldurchführung, etc. etwa von Verschmutzung weitgehend schützen. Die Standfestigkeit der Leuchte kann sich damit weiter verbessern.If at least the housing upper side of the housing rear side of the lamp housing projects, a cover can be formed on the lamp housing in a structurally simple manner. If necessary, this cover can largely protect an electrical cable, an electrical connection, an electrical plug / socket and / or a cable bushing, etc., from contamination. The stability of the lamp can thus continue to improve.

Eine besonders hohe Standfestigkeit an der Leuchte kann erreicht werden, wenn ein Metallblech die Gehäusefrontseite, die Gehäuseoberseite, die Gehäuseunterseite und die beiden Gehäusebreitseiten des Lampengehäuses ausbildet.A particularly high stability on the luminaire can be achieved if a metal sheet forms the housing front side, the upper side of the housing, the underside of the housing and the two housing broad sides of the lamp housing.

Die Leuchte kann konstruktiv vereinfacht und besonders standfest gegenüber widrigsten Umständen an einem Bahngleise ausgebildet werden, wenn die Leuchte eine Vergussmasse aufweist, mit der das Lampengehäuse vergossen ist.The lamp can be structurally simplified and particularly stable against adverse conditions on a railway tracks are formed when the lamp has a potting compound with which the lamp housing is potted.

Bildet die Vergussmasse die Gehäuserückseite aus, kann die Leuchte weiter konstruktiv vereinfacht werden.If the potting compound forms the back of the housing, the luminaire can be further simplified structurally.

Weist die Leuchte eine mit Spiel zum Lampengehäuse vorgesehene Scheibe auf, über die das Leuchtmittel abstrahlt, wobei das Spiel zwischen Scheibe und Lampengehäuse mit Vergussmasse ausgefüllt ist, kann die Standfestigkeit der Leuchte weiter erhöht werden. Die Vergussmasse kann nämlich zur mechanische Entkopplung der Scheibe vom Lampengehäuse dienen, wodurch selbst direkt auf das Lampengehäuse einwirkende Erschütterungen vorteilhaft abgetragen werden können.If the luminaire has a disk provided with play for the lamp housing, through which the illuminant radiates, whereby the clearance between the disk and the lamp housing is filled with potting compound, the stability of the luminaire can be further increased. The potting compound can namely serve for the mechanical decoupling of the disc from the lamp housing, whereby even directly acting on the lamp housing vibrations can be advantageously removed.

Vorzugsweise kann vorgesehen sein, dass das Leuchtmittel über die Frontseite des Lampengehäuses abstrahlen, beispielsweise über eine transparente Teilfläche an der Frontseite des Lampengehäuses.Preferably, it can be provided that the light emitting means radiate over the front side of the lamp housing, for example via a transparent part surface on the front side of the lamp housing.

Die mechanische Verbindung zwischen Klammer und Schienenfuß ist weiter verbesserbar, wenn die Laschen hakenförmig verlaufen - und auf diese Weise die gegenüberliegenden Schmalseiten des Schienenfußes besonders fest geklemmt werden können.The mechanical connection between the clamp and rail foot can be further improved if the tabs are hook-shaped - and in this way the opposite narrow sides of the rail foot can be particularly firmly clamped.

Die Leuchte kann sich besonders bei einer Schiene mit einem Schienenfuß, mit einem Schienensteg und mit einem Schienenkopf eignen.The luminaire may be particularly suitable for a rail with a rail foot, with a rail web and with a rail head.

In den Figuren ist beispielsweise der Erfindungsgegenstand anhand einer Ausführungsvariante näher dargestellt. Es zeigen

  • Fig. 1 eine geschnittene Seitansicht auf die Leuchte, montiert an einer Schiene und
  • Fig. 2 eine vergrößerte Teilansicht der Fig. 1
In the figures, for example, the subject invention is illustrated in more detail with reference to a variant embodiment. Show it
  • Fig. 1 a sectional side view of the lamp, mounted on a rail and
  • Fig. 2 an enlarged partial view of the Fig. 1

Nach Fig. 1 wird die erfindungsgemäße Leuchte 1 beispielsweise dargestellt. Die Leuchte 1 weist ein Lampengehäuse 2 auf, das mehrere LED-Leuchtmittel 3 kapselt. Zudem ist die Leuchte 1 mit einem Verbindungsmittel 4 versehen, das die Leuchte 1 an einer Schiene 5, die einen Schienenfuß 6, einen Schienensteg 7 und einen Schienenkopf 8 aufweist, verbindet.To Fig. 1 For example, the luminaire 1 according to the invention is shown. The lamp 1 has a lamp housing 2, which encapsulates a plurality of LED lamps 3. In addition, the lamp 1 is provided with a connecting means 4, which connects the lamp 1 to a rail 5, which has a rail 6, a rail web 7 and a rail head 8.

Des Weiteren ist erkennbar, dass das Verbindungsmittel 4 konstruktiv ausgebildet ist, das Lampengehäuse 2 über dem Schienenfuß 6 und auf Höhe des Schienenstegs 7 der Schiene 5 eines nur andeutungsweise neben der Schiene 5 dargestellten Bahngleises 9 zu lagern. Durch diese Position der LED-Leuchtmittel 3 kann das Bahngleis 9 bzw. das Gleis verbessert ausgeleuchtet werden. Die erfindungsgemäße Leuchte 1 dient jedoch auch als Gleisbeleuchtung, Gleisfeldbeleuchtung und/oder Beleuchtung von Schienenfahrzeugen bzw. damit generell jedem Beleuchtungszweck.
Im Allgemeinen wird erwähnt, dass jegliche Art von Leuchtmitteln 4 für die Erfindung vorstellbar ist - sich jedoch LED-Leuchtmittel aufgrund ihres Wirkungsgrads und ihrer Standfestigkeit besonders dafür eignen.Furthermore, it can be seen that the connecting means 4 is constructively designed to support the lamp housing 2 above the rail base 6 and at the level of the rail web 7 of the rail 5 of a rail track 9 only hinted at next to the rail 5. This position of the LED light source 3, the railroad track 9 and the track can be improved illuminated. However, the luminaire 1 according to the invention also serves as track lighting, track field lighting and / or lighting of rail vehicles or thus generally any lighting purpose.
In general, it is mentioned that any type of light emitting means 4 for the invention is conceivable - but LED bulbs are particularly suitable because of their efficiency and stability.

Durch eine besondere Ausführung der Verbindungsmittel 4 erreicht die erfindungsgemäße Leuchte 1 eine gegenüber dem Stand der Technik erhöhte Standfestigkeit - und ist dennoch auf einfache Weise an einer Schiene 5 montierbar. Hierfür bildet ein federndes Material, nämlich Flachmaterial, beispielsweise aus einem Federstahl, das Verbindungsmittel 4 aus, das sich selbst in eine Klammer 10 und einen Endabschnitt 11 unterteilt.
Die Klammer 10 dient dem lösbaren Verbinden der Leuchte 1 mit dem Schienenfuß 6. Hierzu weist die Klammer 10 einen zum Untergreifen des Schienenfußes 6 ausgebildeten Unterzug 10.1 und zwei zum Umgreifen von gegenüberliegenden Schmalseiten 6.2, 6.3 des Schienenfußes 6 ausgebildete Laschen 10.2, 10.3 auf. Diese Laschen 10.2, 10.3 schließen an den Unterzug 10.1 an und klemmen unter Ausnützung der federnden Eigenschaft des Materials den Schienenfuß 6 am Verbindungsmittel 4 fest.By a particular embodiment of the connecting means 4, the luminaire 1 according to the invention achieves an increased stability compared with the prior art - and yet can be easily mounted on a rail 5. For this purpose, forms a resilient material, namely flat material, for example of a spring steel, the connecting means 4, which divides itself into a clamp 10 and an end portion 11.
The clamp 10 is used for releasably connecting the lamp 1 with the rail 6. For this purpose, the clamp 10 has a trained under the rail foot 6 beam 10.1 and two for grasping opposite narrow sides 6.2, 6.3 of the rail 6 trained tabs 10.2, 10.3. These tabs 10.2, 10.3 close to the beam 10.1 and clamp using the resilient property of the material the rail 6 on the connecting means 4 fixed.

Der Endabschnitt 11 dient unter anderem der Befestigung und Positionierung des Lampengehäuses 2. Hierzu schließt der Endabschnitt 11 an einer ersten Lasche 10.2 der beiden Laschen 10.2, 10.3 an - nämlich zu dieser Lasche 10.3 nach außen abgewinkelt, was in Fig. 2 am stumpfen Winkel 12 zwischen Lasche 10.3 und Endabschnitt 11 zu erkennen ist. Der Endabschnitt 11 ist also dazu ausgebildet, das Lampengehäuse 2 über dem Schienenfuß 6 auf Höhe des Schienenstegs 7 der Schiene 5 federnd zu lagern. Erschütterungen werden daher von der Federung vom Lampengehäuse 2 bzw. dem darin gekapselten Leuchtmittel 3 und/oder der Elektronik ferngehalten - was der Leuchte 1 eine besonders hohe Standfestigkeit gibt.Among other things, the end portion 11 is used for fastening and positioning the lamp housing 2. For this purpose, the end portion 11 connects to a first tab 10.2 of the two tabs 10.2, 10.3 - namely angled outwardly to this tab 10.3, which in Fig. 2 can be seen at the obtuse angle 12 between tab 10.3 and end portion 11. The end portion 11 is thus adapted to the Lamp housing 2 on the rail 6 to store at the level of the rail web 7 of the rail 5 resiliently. Shocks are therefore kept away from the suspension of the lamp housing 2 and the encapsulated lamp 3 and / or the electronics - which gives the lamp 1 a very high stability.

Außerdem ist in der Fig. 1 zu erkennen, dass die Gehäuseunterseite 2.1 des Lampengehäuses 2 am Endabschnitt 11 des Verbindungsmittels 4 befestigt ist - vorzugsweise stoffschlüssig verbunden, nämlich verschweißt.Moreover, in the Fig. 1 to recognize that the housing bottom 2.1 of the lamp housing 2 is fixed to the end portion 11 of the connecting means 4 - preferably cohesively connected, namely welded.

Das Lampengehäuse 2 weist zudem im Querschnitt eine Parallelogrammform auf, was unter Berücksichtigung der Befestigung am abgewinkelten Endabschnitt 11 einen geneigte Lage des Lampengehäuses 2 zur Schiene 5 sicherstellt - und damit das Lampengehäuses 2 vor einem Anbacken von Verschmutzung schützt.The lamp housing 2 also has a parallelogram in cross section, which, taking into account the attachment to the angled end portion 11 ensures an inclined position of the lamp housing 2 to the rail 5 - and thus protects the lamp housing 2 from caking of dirt.

Zudem weist das Lampengehäuse 2 an seiner Gehäuserückseite 2.2 eine Kabeldurchführung 13 auf, durch welche ein elektrisches Kabel 14 zur elektrischen Verbindung, beispielsweise Energieversorgung und/oder zur Ansteuerung, der Lampe 1 geführt ist. Die Kabeldurchführung 13 weist ein nicht näher dargestelltes Entlüftungsventil auf. Dadurch kann die Kabeldurchführung 13 atmungsaktiv zur mechanisch und einseitig hydroskopisch dichten Durchführung eines geschirmten oder ungeschirmten elektrischen Kabels 14 mit/ohne Zugentlastung mit/ohne Biegeschutz für dieses Kabel 14 ausgebildet sein.In addition, the lamp housing 2 has on its rear side of the housing 2.2 a cable feedthrough 13, through which an electrical cable 14 for electrical connection, for example, power supply and / or for driving, the lamp 1 is performed. The cable bushing 13 has a vent valve not shown in detail. As a result, the cable feedthrough 13 can be designed to be breathable for mechanically and unilaterally hydroscopically impermeable passage of a shielded or unshielded electrical cable 14 with / without strain relief with / without bending protection for this cable 14.

Im Allgemeinen wird erwähnt, dass das vom Lampengehäuse 2 abstehende, elektrische Kabel 14 an der Schiene 5 anliegen kann, wie dies in Fig. 2 zu erkennen ist, um damit das Lampengehäuse 2 über dem Schienenfuß 6 auf Höhe des Schienenstegs 7 der Schiene 5 gedämpft federnd zu lagern.In general, it is mentioned that the electrical cable 14 projecting from the lamp housing 2 can rest against the rail 5, as shown in FIG Fig. 2 can be seen, so as to support the lamp housing 2 on the rail 6 at the height of the rail web 7 of the rail 5 damped resiliently.

Indem - wie insbesondere in Fig. 2 zu erkennen - die Gehäuseoberseite 2.3 und zudem auch die Gehäuseunterseite 2.1 und die beiden Gehäusebreitseiten 2.4, 2.5 der Gehäuserückseite 2.2 des Lampengehäuses 2 vorspringen, kann - auf konstruktiv einfache Weise gelöst - die elektrische Verbindung abgedeckt und damit gegenüber Umwelteinflüssen geschützt werden. Dies erhöht wiederum die Standfestigkeit der Leuchte 2.By - as in particular in Fig. 2 to recognize - the housing top 2.3 and also the bottom of the housing 2.1 and the two sides of the housing 2.4, 2.5 of the housing rear side 2.2 of the lamp housing 2 project, can - on constructive solved simple way - the electrical connection covered and thus protected against environmental influences. This in turn increases the stability of the luminaire 2.

Diese Standfestigkeit wird weitere verbessert, indem ein Metallblech die Gehäusefrontseite 2.6, die Gehäuseoberseite 2.3, Gehäuseunterseite 2.1 und die beiden Gehäusebreitseiten 2.4, 2.5 des Lampengehäuses 2 ausbildet.This stability is further improved by a metal sheet, the housing front side 2.6, the housing top 2.3, housing bottom 2.1 and the two housing sides 2.4, 2.5 of the lamp housing 2 forms.

Beispielsweise können diese Seiten 2.1, 2.3, 2.4, 2.5, 2.6 des Lampengehäuses 2 in einem Umformschritt aus einer Blechplatine geschaffen werden. Damit ist eine Wanne herstellbar, welche - mit einer Vergussmasse 14 gefüllt - das Leuchtmittel 3 verkapselt. Diese Vergussmasse 14 bildet dann auch die Gehäuserückseite 2.2 des Lampengehäuses 2 aus.For example, these pages 2.1, 2.3, 2.4, 2.5, 2.6 of the lamp housing 2 can be created in a forming step from a sheet metal blank. For a tub can be produced, which - filled with a potting compound 14 - encapsulated the bulb 3. This potting compound 14 then forms the housing rear side 2.2 of the lamp housing 2.

In der Gehäusefrontseite 2.6 ist eine Ausnehmung 15 vorgesehen, in die eine transparente Scheibe 16 mit umlaufenden Spiel 17 zum Lampengehäuse 2 eingesetzt ist. Über diese Scheibe 16 strahlt das Leuchtmittel 3 über die Frontseite 2.6 ab. Im Spiel zwischen Lampengehäuse 2 und transparenter Scheibe 16 ist Vergussmasse 14 vorgesehen, was zu einer mechanischen Entkopplung beider Gehäuseteile beiträgt.In the housing front side 2.6, a recess 15 is provided, in which a transparent disc 16 is inserted with circumferential play 17 to the lamp housing 2. About this disc 16 radiates the bulb 3 on the front 2.6. In the game between the lamp housing 2 and transparent disc 16 potting compound 14 is provided, which contributes to a mechanical decoupling of the two housing parts.

Zudem kann der Fig. 1 entnommen werden, dass die beiden Laschen 10.2, 10.3 hakenförmig verlaufen, womit die gegenüberliegenden Schmalseiten des Schienenfußes besonders fest geklemmt werden.In addition, the Fig. 1 be taken that the two tabs 10.2, 10.3 are hook-shaped, so that the opposite narrow sides of the rail foot are particularly firmly clamped.
