Weiters betrifft die Erfindung eine Leuchtsignalvorrichtung aufweisend ein Gehäuse und zumindest ein Leiterplattenelement mit zumindest einem Leuchtelement zur Abgabe eines Signallichtes und ein Verfahren zur Herstellung eines Gehäuses zur Aufnahme zumindest eines Leiterplattenelements mit zumindest einem Leuchtelement zur Abgabe eines Signallichtes, wobei eine Linsenvorrichtung zur Streuung und/oder Sammlung des vom zumindest einen Leuchtelement abgegebenen Signallichtes vorgesehen ist, aufweisend eine Mantelfläche mit einer Lichtaustrittsfläche und eine die Mantelfläche in eine axiale Richtung im Wesentlichen begrenzende Deckfläche.The invention relates to a housing for accommodating at least one printed circuit board element with at least one lighting element for emitting a signal light, with a lens device for scattering and/or collecting the signal light emitted by the at least one lighting element being provided, having a lateral surface with a light exit surface and a lateral surface that converts into a axial direction substantially delimiting top surface. The invention also relates to a light signal device having a housing and at least one circuit board element with at least one light element for emitting a signal light, and a method for producing a housing for accommodating at least one circuit board element with at least one light element for emitting a signal light, with a lens device for scattering and/or Collection of the signal light emitted by at least one light-emitting element is provided, having a lateral surface with a light exit surface and a top surface that essentially delimits the lateral surface in an axial direction.

Im Stand der Technik sind Warnleuchten mit zylindrischer Lichtaustrittsfläche und hauptsächlich radialer Lichtabstrahlung, welche rundum gleichmäßig erfolgt, bekannt. Die Lichtabstrahlung kann im Fall einer Wandmontage beispielsweise auch nur halbzylindrisch mit einer 180°-Abstrahlung erfolgen. Weiters kann ein beliebig anderer Sektorenwinkel ausgestrahlt werden. Dabei können im Inneren der Warnleuchte LEDs als Lichtquelle so angeordnet sein, dass ihre Hauptabstrahlrichtung bereits radial orientiert ist.Warning lights with a cylindrical light exit surface and mainly radial light emission, which is uniform all around, are known in the prior art. In the case of wall mounting, for example, the light emission can also only be semi-cylindrical with a 180° emission. Furthermore, any other sector angle can be broadcast. LEDs can be arranged as a light source inside the warning light in such a way that their main emission direction is already oriented radially.

Es ist eine Vielzahl von Signalvorrichtungen, insbesondere Leuchtsignalvorrichtungen bekannt. Insbesondere sind Leuchtsignalvorrichtungen mit einem, gegebenenfalls eingefärbtem, Gehäuse, das beispielsweise zylindrisch ist, bekannt, in deren Inneren mit auf einem oder mehreren Leiterplattenelementen befestigten Leuchtdioden (LEDs) ein Leuchtsignal abgegeben werden kann.A large number of signaling devices, in particular luminous signaling devices, are known. In particular, luminous signal devices are known with an optionally colored housing, which is cylindrical for example, and inside which a luminous signal can be emitted using light-emitting diodes (LEDs) attached to one or more printed circuit board elements.

Solche Leuchtsignalvorrichtungen, insbesondere Warnleuchten, weisen üblicherweise eine umlaufende Lichtaustrittsfläche, auch als Kalotte bezeichnet, mit einer Deckfläche als Abschluss oder zur Stabilisierung auf. Darin befindet sich zumindest eine oder mehrere regelmäßig angeordnete Platinen, die im Wesentlichen parallel zur Achsrichtung der Warnleuchte angeordnet sind und zumeist mehrere LEDs in einer Reihe aufweisen, sowie eine Reihe von Primärlinsen, welche unmittelbar vor den LEDs angeordnet sind und deren Lichtstärke in Umfangsrichtung vergleichmäßigen und die Breite der Abstrahlung nach dem Einsatzzweck und erforderlichen Sichtbereich einstellen. Häufig ist ebenfalls eine Streustruktur auf der Kalotten-Innenfläche vorhanden, welche vor allem durch Verbreitern der ansonsten punktförmig erscheinenden Lichtquellen für ein gutes Erscheinungsbild der Leuchte sorgen.Such light signal devices, in particular warning lights, usually have a circumferential light exit surface, also referred to as a cap, with a top surface as a conclusion or for stabilization. It contains at least one or more regularly arranged circuit boards, which are arranged essentially parallel to the axis direction of the warning light and usually have several LEDs in a row, as well as a row of primary lenses, which are arranged directly in front of the LEDs and whose light intensity is evened out in the circumferential direction and Adjust the width of the radiation according to the application and required field of view. There is also often a scattering structure on the inner surface of the cap, which ensures a good appearance of the luminaire, primarily by widening the otherwise punctiform appearing light sources.

Eine vorteilhafte Ausführungsform von Warnleuchten wird von der EP 3 043 111 B1 offenbart. Diese schlägt eine Signalvorrichtung vor, die aus mehreren Signalmodulen aufgebaut ist. Das Signalmodul enthält dabei ein Leiterplattenelement mit LEDs und das Signalmodul ist lösbar mit einem weiteren Signalmodul mithilfe einer Bajonettverbindung verbindbar, wobei die Signalmodule im verbundenen Zustand übereinander angeordnet sind und von den verbundenen Signalmodulen eine durchgehende Leiterbahn über die Leiterplattenelemente gebildet wird. Zusätzlich zu dem beispielsweise in einem Stück gespritzten Gehäuse, bestehend aus einer Mantelfläche und einer Deckfläche, kann ein extra hinzuzufügendes Optikelement mit Linsen vorgesehen sein, mit welchen die von einer jeweils zugehörigen LED abgegebenen Lichtstrahlen verteilt bzw. gerichtet werden. Die Fertigung dieser Signalvorrichtung bzw. eines Signalmoduls ist allerdings aufwendig, da zusätzlich ein Optikelement mit Linsen hergestellt und im Signalmodul befestigt werden muss.An advantageous embodiment of warning lights is of the EP 3 043 111 B1 disclosed. This proposes a signaling device that is made up of several signaling modules. The signal module contains a printed circuit board element with LEDs and the signal module can be releasably connected to another signal module using a bayonet connection, the signal modules being arranged one above the other when connected and a continuous conductor path over the printed circuit board elements being formed by the connected signal modules. In addition to the housing, which is injection-molded in one piece and consists of a lateral surface and a cover surface, an additional optical element with lenses can be provided, with which the light beams emitted by a respective associated LED are distributed or directed. However, the manufacture of this signaling device or a signaling module is complex, since an optical element with lenses must also be manufactured and fastened in the signaling module.

Weiters zeigen die EP 3 199 866 A1 , die EP 2 878 879 A1 , die WO 2009/125160 A1 und die JP 2005 044738 A gestapelte Signallampen.Further show the EP 3 199 866 A1 , the EP 2 878 879 A1 , the WO 2009/125160 A1 and the JP 2005 044738 A stacked signal lamps.

Ein Ziel der Erfindung ist es, eine Signalvorrichtung bzw. ein Gehäuse zur Aufnahme eines Leiterplattenelements mit Leuchtelementen zu schaffen, die möglichst einfach hergestellt werden kann, wobei insbesondere weiters

  • die Rundum-Abstrahlung bzw. sektorale Abstrahlung vergleichmäßigt wird,
  • die Abstrahlungsbreite quer zur Umfangsrichtung gebündelt bzw. gestaltet wird,
  • die Lichtabstrahlung aus jeder Betrachtungsrichtung über einen wesentlichen Anteil der sichtbaren Austrittsfläche verteilt wird, und/oder
  • die Bündelung und Vergleichmäßigung in Umfangsrichtung und die Bündelung quer dazu bei virtuellen Drehleuchten erreicht wird.
One aim of the invention is to create a signaling device or a housing for accommodating a printed circuit board element with light-emitting elements, which can be manufactured as simply as possible, in particular further
  • the all-round radiation or sectoral radiation is evened out,
  • the radiation width is bundled transversely to the circumferential direction or is designed,
  • the light emission from each viewing direction is distributed over a substantial proportion of the visible exit surface, and/or
  • the bundling and equalization in the circumferential direction and the bundling across is achieved with virtual rotating lights.

Dies wird in der vorliegenden Erfindung durch ein Gehäuse nach Anspruch 1, eine Leuchtsignalvorrichtung nach Anspruch 13 und ein Verfahren nach Anspruch 14 erzielt. Beim Gehäuse zur Aufnahme zumindest eines Leiterplattenelements wie eingangs beschrieben sind die Linsenvorrichtung und die Deckfläche einstückig ausgebildet, wobei die Linsenvorrichtung nicht in direktem Kontakt mit der Mantelfläche ist, wobei die Linsenvorrichtung ausschließlich über die Deckfläche mit der Mantelfläche in Verbindung steht, wobei die Linsenvorrichtung von der Lichtaustrittsfläche der Mantelfläche einen Abstand von mehr als dem 0,5-fachen der radialen Erstreckung des Gehäuses aufweist. Weiters sind bei der Leuchtsignalvorrichtung wie eingangs beschrieben das Gehäuse und das zumindest eine Leiterplattenelement entsprechend ausgeführt, wobei bevorzugt das zumindest eine Leuchtelemente jeweils eine LED ist, die besonders bevorzugt linsenlos ist, einen ebenen Lichtaustritt aufweist und/oder als oberflächenmontiertes Bauelement (SMD) ausgeführt ist und beim Verfahren zur Herstellung eines Gehäuses wie eingangs beschrieben werden die Linsenvorrichtung und die Deckfläche einstückig hergestellt, wobei bevorzugt die Linsenvorrichtung unmittelbar entformbar oder mit einer Werkzeug-Konstruktionsweise, besonders bevorzugt einem Innenschieber, einem Zweistufen-Auswerfer, einem Schräg-Auswerfer, einem Feder-Auswerfer oder einem Einfallkern, entformbar hergestellt wird, wobei die Linsenvorrichtung nicht in direktem Kontakt mit der Mantelfläche ist, wobei die Linsenvorrichtung ausschließlich über die Deckfläche mit der Mantelfläche in Verbindung steht, wobei die Linsenvorrichtung von der Lichtaustrittsfläche der Mantelfläche einen Abstand von mehr als dem 0,5-fachen der radialen Erstreckung des Gehäuses aufweist.This is achieved in the present invention by a housing according to claim 1, a beacon device according to claim 13 and a method according to claim 14. In the case of the housing for accommodating at least one printed circuit board element, as described above, the lens device and the top surface are designed in one piece, with the lens device not being in direct contact with the lateral surface, with the lens device being connected to the lateral surface exclusively via the top surface, with the lens device being Light exit surface of the lateral surface has a distance of more than 0.5 times the radial extent of the housing. Furthermore, in the light signal device, the housing and the at least one printed circuit board element are designed accordingly, as described at the outset, with the at least one lighting element preferably being an LED in each case, which is particularly preferably lensless, has a planar light exit and/or is designed as a surface-mounted component (SMD). and in the method for producing a housing as described at the outset, the lens device and the cover surface are produced in one piece, with the lens device preferably being able to be removed from the mold directly or with a tool design, particularly preferably an internal slide, a two-stage ejector, an inclined ejector, a spring Ejector or a collapsing core, is made demouldable, wherein the lens device is not in direct contact with the lateral surface, wherein the lens device is in connection exclusively via the top surface with the lateral surface, wherein the lens device vo n the light exit surface of the lateral surface has a distance of more than 0.5 times the radial extension of the housing.

Die Linsenvorrichtung ist also einstückig bzw. einteilig mit dem Gehäuse, insbesondere der Deckfläche, d. h. sie ist integral mit diesem bzw. dieser ausgebildet. Die Linsenvorrichtung kann dabei eine beliebige Kombination von Linsen und gegebenenfalls eine entsprechende Halterung dieser darstellen. Als Linse können beispielsweise beliebige lichtbrechende, transparente Körper verwendet werden, beispielsweise Sammellinsen, Zerstreuungslinsen, oder Linsen die deren Funktionen kombinieren, z. B. auch richtungsabhängig. Es können auch mehrere Linsenvorrichtungen vorgesehen sein, die jeweils einstückig mit der Deckfläche ausgebildet sind. Weiters ist die Linsenvorrichtung nicht in direktem Kontakt mit der Mantelfläche. Es sind vorteilhafterweise allerdings auch die Deckfläche und die Mantelfläche einstückig ausgebildet.The lens device is therefore in one piece or in one piece with the housing, in particular the top surface, ie it is formed integrally with it. The lens device can represent any combination of lenses and optionally a corresponding holder of these. For example, any light-refracting, transparent body can be used as a lens, for example converging lenses, diverging lenses, or lenses which combine their functions, e.g. B. also dependent on direction. A plurality of lens devices can also be provided, each of which is formed in one piece with the top surface. Furthermore, the lens assembly is not in direct contact with the lateral surface. Advantageously, however, the top surface and the lateral surface are also formed in one piece.

Durch die einstückige Ausbildung werden die Fertigung und die Montage von Linsen, insbesondere von Primärlinsen, eingespart, wobei die technische Leistungsfähigkeit unverändert bleibt. Sofern das Gehäuse, insbesondere die Lichtaustrittsfläche, eingefärbt ist, muss die Wandstärke sowohl des Gehäuses/der Lichtaustrittsfläche als auch der Linsenvorrichtung bei der Bestimmung der notwendigen Farbmenge berücksichtigt werden.The one-piece design saves on the manufacture and assembly of lenses, in particular primary lenses, while the technical performance remains unchanged. If the housing, in particular the light exit surface, is colored, the wall thickness of both the housing/the light exit surface and the lens device must be taken into account when determining the necessary amount of paint.

Die Lichtaustrittsfläche ist insbesondere aus einem transparenten Material gefertigt. Die Lichtaustrittsfläche kann beispielsweise die gesamte oder einen Teil der Mantelfläche umfassen. Definitionsgemäß ist die Lichtaustrittsfläche ein Teil der Mantelfläche, es kann aber auch durch die Deckfläche oder einen Teil derselben Licht abgegeben werden. Der restliche Teil des Gehäuses, der nicht die Lichtaustrittsfläche bildet, kann transparent, teiltransparent oder opak sein.The light exit surface is made in particular from a transparent material. The light exit surface can, for example, encompass all or part of the lateral surface. By definition, the light exit surface is part of the lateral surface, but light can also be emitted through the top surface or part of the same. The remaining part of the housing that does not form the light exit surface can be transparent, partially transparent or opaque.

Die Deckfläche muss nicht die gesamte von einer Oberkante der Mantelfläche gebildete Fläche abdecken. Sie kann beispielsweise auch nur als Verbindungslinie zwischen zwei Stellen der Oberkante ausgebildet sein, wobei die Linsenvorrichtung mit der Verbindungslinie einstückig ausgebildet ist.The top surface does not have to cover the entire surface formed by an upper edge of the lateral surface. It can, for example, also be formed only as a connecting line between two points of the upper edge, with the lens device being formed in one piece with the connecting line.

Die radiale(n) Richtung(en) ist/sind orthogonal zur axialen Richtung. Üblicherweise entspricht die axiale Richtung der Höhenerstreckungsrichtung der Mantelfläche. Die Deckfläche kann im Wesentlichen plan sein, insbesondere auf der der Linsenvorrichtung abgewandten Seite. Sofern die Deckfläche im Wesentlichen plan ist, wird üblicherweise die axiale Richtung normal zur Ebene der Deckfläche sein bzw. die radiale(n) Richtung(en) parallel zur Ebene der Deckfläche.The radial direction(s) is/are orthogonal to the axial direction. The axial direction usually corresponds to the direction in which the lateral surface extends in height. The top surface can be essentially flat, in particular on the side facing away from the lens device. Unless the top surface is essentially is planar, the axial direction will usually be normal to the plane of the top surface or the radial direction(s) parallel to the plane of the top surface.

Es ist vorgesehen, dass die Linsenvorrichtung von der Lichtaustrittsfläche der Mantelfläche einen Abstand von mehr als dem 0,5-fachen, bevorzugt dem 0,7-fachen, der radialen Erstreckung des Gehäuses aufweist. Es beträgt insbesondere ein (insbesondere radialer) Abstand der Linsenvorrichtung (insbesondere jedes Punktes der Linsenvorrichtung) von der Lichtaustrittsfläche (insbesondere jedes Punktes der Lichtaustrittsfläche) mehr als das 0,5-fache, bevorzugt das 0,7-fache der radialen Erstreckung des Gehäuses. Ebenfalls ist es vorteilhaft, wenn eine radiale Erstreckung der Linsenvorrichtung (insbesondere in Richtungen der Lichtaustrittsfläche) im Wesentlichen das 0,15-fache bis 0,6-fache oder weniger als das 0,7-fache, bevorzugt weniger als das 0,5-fache, noch mehr bevorzugt weniger als das 0,3-fache, der radialen Erstreckung der Mantelfläche beträgt. Es können insbesondere linsenlose Leuchtelemente, z. B. LEDs, auf dem Leiterplattenelement vorgesehen sein, die einen ebenen Lichtaustritt aufweisen und/oder als oberflächenmontiertes Bauelement (SMD) ausgeführt sind. Diese haben beispielsweise eine hemisphärische Abstrahlung im Wesentlichen mit einer Cosinus-Verteilung, wobei die größte Abstrahlung in Achsrichtung, d. h. normal zum Leiterplattenelement in üblicher Befestigung des Leuchtelements, erreicht wird und diese mit zunehmender Veränderung des Betrachtungswinkels entsprechend einer Cosinus-Verteilung abnimmt, bei einem Winkel von 90° zur Normalen beträgt sie Null.It is provided that the lens device has a distance of more than 0.5 times, preferably 0.7 times, the radial extension of the housing from the light exit surface of the lateral surface. In particular, a (particularly radial) distance between the lens device (particularly each point of the lens device) and the light exit surface (particularly each point on the light exit surface) is more than 0.5 times, preferably 0.7 times, the radial extension of the housing. It is also advantageous if a radial extent of the lens device (in particular in the direction of the light exit surface) is essentially 0.15 times to 0.6 times or less than 0.7 times, preferably less than 0.5 times. times, more preferably less than 0.3 times, the radial extent of the lateral surface. In particular, lensless lighting elements, e.g. B. LEDs can be provided on the printed circuit board element, which have a flat light exit and / or as a surface-mounted device (SMD) are designed. These have, for example, a hemispherical emission essentially with a cosine distribution, with the greatest emission in the axial direction, i. H. normal to the printed circuit board element in the usual fastening of the lighting element, and this decreases with an increasing change in the viewing angle according to a cosine distribution, at an angle of 90° to the normal it is zero.

Bei der Bauweise mit nur einer Platine würde das Gehäuse beispielsweise im seitlichen Bereich der Platine dunkel bleiben, wenn nicht durch eine Primäroptik bzw. Linsenvorrichtung Licht dorthin gelenkt würde. Ein Zusammenlegen der Linsenvorrichtung bzw. derer Linsen mit den Streulinsen, die häufig auf der Lichtaustrittsfläche vorgesehen sind, würde nicht zum Erfolg führen, da eine räumliche Trennung bzw. Distanz von Linse und Gehäuse zur Vergleichmäßigung benötigt wird.In the construction with only one circuit board, the housing would remain dark, for example, in the lateral area of the circuit board if light were not directed there by a primary optics or lens device. Combining the lens device or its lenses with the scattering lenses, which are often provided on the light exit surface, would not lead to success, since a spatial separation or distance between the lens and the housing is required for equalization.

In einer bevorzugten Ausführungsform des Gehäuses hat die Mantelfläche die Form eines Zylinders, eines Zylindersektor, vorzugsweise eines Halbzylinders, oder eines Zylindersegments, wobei bevorzugt die Lichtaustrittsfläche der Mantelfläche im Wesentlichen dem Bereich der Mantelfläche entspricht, deren Querschnitt normal zur Mantelfläche und/oder normal zur axialen Richtung rund ist. Unter einem Zylindersektor (Zylinderausschnitt) wird dabei der Schnitt eines Zylinders mit einer Ebene verstanden, wobei die Mantelfläche gebildet wird von der Mantelfläche des Zylinders auf einer Seite der Ebene und der von den (insbesondere vier) Schnittlinien des Zylinders mit der Ebene begrenzten Fläche, die auf der Ebene liegt. Die schneidende Ebene ist dabei vorzugsweise parallel zur Mantelfläche und/oder der axialen Richtung des zu schneidenden Zylinders. Ein Zylindersegment entsteht durch den Schnitt eines Zylinder mit zwei Ebenen, die vorzugsweise parallel zur Mantelfläche des Zylinders und/ oder der axialen Richtung sind und bevorzugt jeweils eine Mittelachse der Mantelfläche beinhalten. Der Zylinder, der Zylindersektor bzw. das Zylindersegment sind vorzugsweise aus einem geraden Zylinder gebildet.In a preferred embodiment of the housing, the lateral surface has the shape of a cylinder, a cylinder sector, preferably a half cylinder, or a cylinder segment, with the light exit surface of the lateral surface preferably essentially corresponding to the area of the lateral surface whose cross section is round normal to the lateral surface and/or normal to the axial direction. A cylinder sector (cylinder section) is understood to mean the intersection of a cylinder with a plane, with the lateral surface being formed by the lateral surface of the cylinder on one side of the plane and the surface delimited by the (in particular four) intersection lines of the cylinder with the plane lies on the level. The cutting plane is preferably parallel to the lateral surface and/or the axial direction of the cylinder to be cut. A cylinder segment results from the intersection of a cylinder with two planes, which are preferably parallel to the lateral surface of the cylinder and/or the axial direction and preferably each contain a central axis of the lateral surface. The cylinder, the cylinder sector or the cylinder segment are preferably formed from a straight cylinder.

In einer vorteilhaften Ausführungsform weist die Linsenvorrichtung einen in eine Höhenerstreckungsrichtung bzw. in axialer Richtung der Mantelfläche im Wesentlichen gleich bleibenden Profilquerschnitt durch eine Ebene normal zur Höhenerstreckungsrichtung der Mantelfläche bzw. zur axialen Richtung auf. Somit weist die Linsenvorrichtung einen unmittelbar entformbaren Querschnitt auf und insbesondere im Spritzguss kann das gesamte Gehäuse aus einem Stück gespritzt werden und anschließend einfach und unmittelbar entformt werden. Weiters kann die Linsenvorrichtung einen Profilquerschnitt durch eine Ebene normal zur Höhenerstreckungsrichtung der Mantelfläche bzw. zur axialen Richtung aufweisen, der in eine Höhenerstreckungsrichtung der Mantelfläche bzw. in axialer Richtung eine gleichbleibende Form, allerdings in veränderlicher Größe aufweist, d. h. dass der beschriebene Profilquerschnitt entlang der Höhenerstreckungsrichtung der Mantelfläche bzw. entlang axialer Richtung geometrisch ähnlich, insbesondere nur zentrisch gestreckt, ist. Somit kann die Linsenvorrichtung beispielsweise pyramidenförmig sein, wobei verschiedenste Grundflächen möglich sind und wobei diese vorzugsweise in eine Richtung weg von der Mantelfläche zulaufend sind, sodass sie wiederum unmittelbar entformbar ist. Insbesondere kann die Linsenvorrichtung einen oder mehrere Profil-Linsenstäbe umfassen, die einen in eine Höhenerstreckungsrichtung der Mantelfläche bzw. in axialer Richtung gleich bleibenden Profilquerschnitt durch eine Ebene normal zur Höhenerstreckungsrichtung der Mantelfläche bzw. zur axialen Richtung aufweisen, wobei diese dementsprechend das Licht nur in radiale Richtungen manipulieren, d. h. streuen oder fokussieren, können, während konstruktinosbedingt eine axiale Manipulation (aufgrund des in dieser Richtung gleichbleibenden Profilquerschnitts) nicht oder nur sehr eingeschränkt möglich ist. Beispielsweise kann der Lichtstrahl in radialer (Umfangs-)Richtung über einen bestimmten azimutalen Winkelbereich vergleichmäßigt werden.In an advantageous embodiment, the lens device has a profile cross section that remains essentially the same in a height extension direction or in the axial direction of the lateral surface through a plane normal to the height extension direction of the lateral surface or to the axial direction. Thus, the lens device has a cross-section that can be removed from the mold immediately, and in particular in injection molding, the entire housing can be molded in one piece and then easily and directly removed from the mold. Furthermore, the lens device can have a profile cross-section through a plane normal to the direction of height of the lateral surface or to the axial direction, which has a constant shape in a direction of height of the lateral surface or in the axial direction, but of variable size, i.e. the profile cross-section described along the direction of height is geometrically similar to the lateral surface or along the axial direction, in particular only stretched centrally. The lens device can thus be pyramid-shaped, for example, with a wide variety of base surfaces being possible and with these preferably tapering in a direction away from the lateral surface are, so that they in turn can be demoulded immediately. In particular, the lens device can comprise one or more profile lens rods, which have a profile cross section that remains the same in a direction of height extension of the lateral surface or in the axial direction through a plane normal to the direction of height extension of the lateral surface or to the axial direction, with these correspondingly only directing the light in the radial direction Directions can be manipulated, ie scattering or focusing, while axial manipulation (due to the profile cross-section remaining the same in this direction) is not possible or only possible to a very limited extent due to the design. For example, the light beam can be equalized in the radial (circumferential) direction over a specific azimuthal angular range.

Selbstverständlich können zusätzlich zur einstückig ausgebildeten Linsenvorrichtung weitere Linsen vorgesehen sein.Of course, further lenses can be provided in addition to the one-piece lens device.

In einer bevorzugten Ausführungsform weist die Linsenvorrichtung zumindest eine Linsenkuppe auf, wobei die zumindest eine Linsenkuppe vorzugsweise jeweils einem Leuchtelement zugeordnet ist, d. h. dass nach der Aufnahme des Leiterplattenelements die Linsenkuppe sich vor dem Leuchtelement (in Richtung des Gehäuses bzw. eines Teils der Lichtaustrittsfläche) befindet. Unter Linsenkuppe wird dabei insbesondere eine linsenförmige Einbuchtung bzw. Ausbuchtung der Linsenvorrichtung verstanden. Mithilfe von Linsenkuppen ist es möglich, die Lichtausbreitung nicht nur in radialer, sondern auch in axialer Richtung zu manipulieren. Beispielsweise kann der Lichtstrahl in radialer Richtung über einen bestimmten azimutalen Winkelbereich vergleichmäßigt werden, wohingegen er in einen bestimmten axialen, d. h. polaren, Winkelbereich fokussiert wird. Die Linsenkuppen können dementsprechend kompliziert ausgestaltet sein, wobei sie mit bekannten Werkzeug-Konstruktionsweisen, beispielsweise einem Innenschieber, einem Zweistufen-, Schräg- oder Feder-Auswerfer, oder einem Einfallkern, entformbar sind bzw. nach dem Spritzguss entformt werden.In a preferred embodiment, the lens device has at least one lens dome, wherein the at least one lens dome is preferably associated with a respective lighting element, i. H. that after the recording of the circuit board element, the lens cap is located in front of the lighting element (in the direction of the housing or a part of the light exit surface). In this context, a lens cap is understood to mean, in particular, a lens-shaped indentation or bulge of the lens device. With the help of lens domes, it is possible to manipulate the light propagation not only in the radial but also in the axial direction. For example, the light beam can be equalized in the radial direction over a specific azimuthal angular range, whereas it is directed in a specific axial, i. H. polar, angular range is focused. Accordingly, the lens tips can have a complicated design, and they can be removed from the mold with known mold designs, for example an internal slide, a two-stage, inclined or spring ejector, or a collapsible core, or are removed from the mold after injection molding.

Unter dem azimutalen Winkel wird ein Winkel zwischen zwei Linien normal zur Höhenerstreckungsrichtung der Mantelfläche bzw. zur axialen Richtung verstanden. Der polare Winkel beschreibt einen Winkel zwischen zwei Linien, die in der Ebene der Höhenerstreckungsrichtung liegen bzw. parallel zur radialen Richtung/normal zur axialen Richtung sind, wobei der beschriebene Winkelbereich insbesondere drehsymmetrisch um einen Mittelpunkt der Mantelfläche (bzw. innerhalb des festgelegten azimutalen Winkelbereichs) zu betrachten ist und die Linien ebenfalls bevorzugt eine Ober- und eine Unterkante der Lichtaustrittsfläche schneiden. Die azimutalen und polaren Winkel werden entsprechend Zylinderkoordinaten verstanden, wobei die z-Achse der axialen Richtung entspricht und die x- und die y-Achse (die einem Polarkoordinatensystem entsprechen) normal zur axialen Richtung bzw. parallel zur radialen Richtung sind. Der azimutale Winkelbereich umfasst somit bis zu 360°, während der polare bis zu 180° umfasst.The azimuthal angle is understood to mean an angle between two lines normal to the height extension direction of the lateral surface or to the axial direction. The polar angle describes an angle between two lines that are in the plane of the height extension direction lie or are parallel to the radial direction/normal to the axial direction, with the angle range described being to be considered in particular as rotationally symmetrical about a center point of the lateral surface (or within the defined azimuthal angle range) and the lines also preferably an upper and a lower edge of the light exit surface cut. The azimuthal and polar angles are understood according to cylindrical coordinates, with the z-axis corresponding to the axial direction and the x- and y-axes (which correspond to a polar coordinate system) being normal to the axial direction and parallel to the radial direction, respectively. The azimuthal angle range is up to 360°, while the polar range is up to 180°.

Im Fall von Profil-Linsenstäben können die Anzahl und die Position der Leuchtelemente auf dem zu verwendenden Leiterplattenelement im Wesentlichen frei gewählt werden, wobei vorteilhafterweise die Leuchtelemente in einer Reihe auf einer Linie parallel zur Höhenerstreckungsrichtung der Mantelfläche bzw. der Linsenvorrichtung/des Profil-Linsenstabes angeordnet sind. Im Fall von Linsenkuppen ist die Anzahl und Position der Leuchtelemente auf dem anzubringenden Leiterplattenelement üblicherweise vorbestimmt. Es sind auch Kombinationen aus Profil-Linsenstäben und Linsenkuppen möglich.In the case of profile lens rods, the number and position of the light-emitting elements on the printed circuit board element to be used can essentially be freely selected, with the light-emitting elements advantageously being arranged in a row on a line parallel to the height extension direction of the lateral surface or the lens device/profile lens rod are. In the case of lens domes, the number and position of the light-emitting elements on the printed circuit board element to be attached is usually predetermined. Combinations of profile lens rods and lens caps are also possible.

Das vorgeschlagene Gehäuse kann insbesondere dazu geeignet sein, dass mehrere solcher Gehäuse übereinander angebracht werden und beispielsweise mithilfe einer Bajonettverbindung miteinander verbunden werden, wobei vorzugsweise die aufgenommenen Leiterplattenelemente eine durchgehende Verbindungsleitung bilden. Die Ausgestaltung des Gehäuses, mit Ausnahme der Linsenvorrichtung und des aufzunehmende Leiterplattenelements, die mit der Deckfläche einstückig ausgebildet sein soll, kann insbesondere entsprechend der im EP 3 043 111 B1 vorgeschlagenen erfolgen, die hiermit durch Referenz vollumfänglich in dieser Anmeldung aufgenommen sein soll.The proposed housing can be suitable in particular for several such housings to be fitted one above the other and to be connected to one another, for example using a bayonet connection, with the printed circuit board elements that are accommodated preferably forming a continuous connecting line. The configuration of the housing, with the exception of the lens device and the circuit board element to be accommodated, which is to be designed in one piece with the top surface, can, in particular, correspond to the EP 3 043 111 B1 Proposed take place, which is hereby fully incorporated by reference in this application.

Es ist vorteilhaft, wenn die Linsenvorrichtung jeweils eine Nut zur Aufnahme eines Leiterplattenelements und/oder einer Reihe von auf einer Linie im Wesentlichen parallel zur Höhenerstreckungsrichtung der Mantelfläche angeordneten Leuchtelemente aufweist. Die Einstückigkeit der gesamten Linsenvorrichtung bzw. aller Linsen mit dem Gehäuse, insbesondere der Deckfläche, erlaubt bei der Verwendung von mehreren solchen auf einer Linie angeordneten Reihen von Leuchtelementen die mechanische Verbindung der (jeweils einer solche Reihe zugeordneten) Linsen untereinander und damit eine erhebliche Verbesserung der inneren Stabilität, insbesondere sofern jeweils eine solche Reihe von Leuchtelementen in axialen Nuten, d. h. solchen in eine Höhenerstreckungsrichtung der Mantelfläche, gehalten werden.It is advantageous if the lens device has a groove for accommodating a printed circuit board element and/or a row of light-emitting elements arranged on a line essentially parallel to the height extension direction of the lateral surface. The integral nature of the entire lens device or all lenses with the housing, in particular the cover surface, allows the mechanical connection of the lenses (each assigned to such a row) to one another and thus a significant improvement in the use of several such rows of lighting elements arranged in a line internal stability, in particular if such a row of light-emitting elements is held in axial grooves, ie in a direction in which the lateral surface extends in height.

Insbesondere wenn die Mantelfläche entsprechend der Mantelfläche eines Zylinders ausgebildet ist, stellt es eine bevorzugte Ausführungsform dar, wenn die Aufnahme genau eines Leiterplattenelements, das bevorzugt Leuchtelemente auf beiden Seiten aufweist, die sich besonders bevorzugt jeweils auf einer Linie parallel zur Höhenerstreckungsrichtung der Mantelfläche befinden, vorgesehen ist und die Linsenvorrichtung zwei Profil-Linsenstäbe aufweist, zwischen die das Leiterplattenelement eingefügt werden kann. Eine Bauweise mit einer großen Leiterplatte mit Leuchtelementen, insbesondere LEDs, auf der Vorder- und Hinterseite, die durch zwei Profil-Linsenstäbe gehalten wird, welche für rundum gleiche Helligkeit sorgen, indem jeder Profil-Linsenstab das Licht in Umfangsrichtung über einen azimutalen Winkelbereich von 180° vergleichmäßigt, ist besonders kostengünstig und weist eine gute innere Wärmeabfuhr auf. Bei dieser Ausführungsform ist es vorteilhaft, wenn die Linsenvorrichtung von der Lichtaustrittsfläche der Mantelfläche einen Abstand von mehr als dem 0,5-fachen, bevorzugt dem 0,75-fachen, noch mehr bevorzugt dem 0,85-fachen der radialen Erstreckung des Gehäuses aufweist. Es beträgt insbesondere einen (insbesondere radialen) Abstand der Linsenvorrichtung (insbesondere jedes Punktes der Linsenvorrichtung) von der Lichtaustrittsfläche (insbesondere jedes Punktes der Lichtaustrittsfläche) mehr als des 0,5-fachen, bevorzugt des 0,75-fachen, noch mehr bevorzugt dem 0,85-fachen der radialen Erstreckung des Gehäuses. Ebenfalls ist es vorteilhaft, wenn eine radiale Erstreckung der Linsenvorrichtung im Wesentlichen das 0,15-fache bis 0,25-fache der radialen Erstreckung der Mantelfläche beträgt.In particular, if the lateral surface is designed to correspond to the lateral surface of a cylinder, it is a preferred embodiment if exactly one printed circuit board element is provided, which preferably has lighting elements on both sides, which are particularly preferably each located on a line parallel to the height extension direction of the lateral surface and the lens device has two profile lens rods between which the circuit board element can be inserted. A construction with a large printed circuit board with light elements, especially LEDs, on the front and back, which is held by two profile lens rods, which ensure uniform brightness all around, with each profile lens rod directing the light in the circumferential direction over an azimuthal angular range of 180 ° evened out, is particularly inexpensive and has good internal heat dissipation. In this embodiment, it is advantageous if the lens device has a distance of more than 0.5 times, preferably 0.75 times, even more preferably 0.85 times the radial extension of the housing from the light exit surface of the lateral surface . In particular, a (particularly radial) distance of the lens device (particularly each point of the lens device) from the light exit surface (particularly each point of the light exit surface) is more than 0.5 times, preferably 0.75 times, even more preferably 0 .85 times the radial extension of the housing. It is also advantageous if a radial extent of the lens device is essentially 0.15 to 0.25 times the radial extent of the lateral surface.

In einer bevorzugten Ausführungsform weist die Mantelfläche des Gehäuses die Form der Mantelfläche eines Halbzylinders auf, wobei die Lichtaustrittsfläche der runden Fläche der Mantelfläche (und gegebenenfalls der Deckfläche) entspricht, wobei als Linsenvorrichtung ein Profil-Linsenstab vorgesehen ist, wobei zwischen der der planen Fläche der Mantelfläche und dem Profil-Linsenstab ein Spalt zur Aufnahme des Leiterplattenelements vorgesehen ist. Das Leiterplattenelement weist auf der im aufgenommenen Zustand der Lichtaustrittsfläche zugewandten Seite zumindest ein Leuchtelement auf, vorzugsweise jedoch eine Reihe von Leuchtelementen, die auf einer Linie parallel zur Höhenerstreckungsrichtung der Mantelfläche angeordnet sind, wobei der Profil-Linsenstab angeordnet ist, um als Linse dieser Reihe von Leuchtelementen zu dienen. Die Erfindung kann somit auch bei einer sektoralen Bauweise der zu bildenden Warnleuchte verwendet werden, etwa bei halbseitiger Abstrahlung im Fall einer Wandmontage.In a preferred embodiment, the lateral surface of the The housing has the shape of the lateral surface of a semi-cylinder, with the light exit surface corresponding to the round surface of the lateral surface (and possibly the top surface), with a profile lens rod being provided as the lens device, with a gap between the planar surface of the lateral surface and the profile lens rod is provided for receiving the circuit board element. The printed circuit board element has at least one lighting element on the side facing the light exit surface in the recorded state, but preferably a row of lighting elements, which are arranged on a line parallel to the height extension direction of the lateral surface, with the profile lens rod being arranged in order to be used as a lens in this row of to serve lighting elements. The invention can thus also be used with a sectoral construction of the warning light to be formed, for example with half-sided radiation in the case of wall mounting.

Die beiden letztgenannten Ausführungsformen sind auch möglich mit der Verwendung von Linsenkuppen in der Linsenvorrichtung anstatt der Profil-Linsenstäbe, welche das Licht nicht nur in Umfangsrichtung über einen azimutalen Winkelbereich von 2 mal 180° bzw. von 180° durch Streuen vergleichmäßigen, sondern auch quer dazu, d. h. in einen polaren Winkelbereich, bündeln. Hierdurch kann eine höhere Umfangshelligkeit auf Kosten der Axialhelligkeit erzielt werden. Dies stellt beispielsweise eine typische Bauweise für Warnleuchten-Säulen dar.The two last-mentioned embodiments are also possible with the use of lens caps in the lens device instead of the profile lens rods, which not only make the light more uniform in the circumferential direction over an azimuthal angular range of 2 times 180° or 180° by scattering, but also transversely to it , i.e. H. into a polar angular range. As a result, a higher peripheral brightness can be achieved at the expense of the axial brightness. This represents, for example, a typical design for warning light columns.

In einer vorteilhaften Ausführungsform ist die Aufnahme mehrerer Leiterplattenelemente vorgesehen, die im Wesentlichen entlang eines Kreisbogens, bevorzugt eines Kreises, aufgenommen werden, dessen Mittelpunkt bevorzugt mit einem Mittelpunkt der Mantelfläche übereinstimmt, wobei die Leuchtelemente der Leiterplattenelemente vorzugsweise auf Linien parallel zur Höhenerstreckungsrichtung der Mantelfläche und schneidend den Kreisbogen angeordnet sind. D. h. die Leiterplattenelemente sind im aufgenommenen Zustand derart angeordnet, dass die Mittelpunkte der Leiterplattenelemente auf einem Kreisbogen, vorzugsweise regelmäßig beabstandet, liegen bzw. deren Mittelachsen in Höhenerstreckungsrichtung der Mantelfläche schneiden, so dass das jeweils eine Leuchtelement der Leiterplattenelemente auf einem Kreisbogen, vorzugsweise regelmäßig beabstandet, liegt oder dass die Linien parallel zur Höhenerstreckungsrichtung der Mantelfläche, auf denen eine Reihe von Leuchtelementen angeordnet sind, auf jeweils einem Leiterplattenelement auf einem Kreisbogen, vorzugsweise regelmäßig beabstandet, liegen. Die Linsenvorrichtung weist vorzugsweise Linsenkuppen auf, die jeweils das Licht eines Leuchtelements oder das Licht mehrerer Leuchtelemente eines Leiterplattenelements beeinflussen. Dabei kann die Linsenvorrichtung selbst im Wesentlichen die gleiche Form wie die Mantelfläche, nur mit einem geringeren Durchmesser, aufweisen, wobei Linsenkuppen an ihrer Oberfläche, jeweils einem Leuchtelement zugeordnet, angeordnet sind. Es sind vorzugsweise mehrere schmale Leiterplattenelemente mit je einer Reihe auf einer Linie parallel zur Höhenerstreckungsrichtung der Mantelfläche angeordneten Leuchtelementen so im Kreis angeordnet, dass die Leuchtelemente radial nach außen leuchten und deren Licht je durch eine Linse entweder nur in Umfangsrichtung gestreut oder gesammelt wird oder zusätzlich auch senkrecht dazu verteilt oder gesammelt wird. Bei dieser Ausführungsform, bei der die Aufnahme mehrerer Leiterplattenelemente vorgesehen ist, ist es vorteilhaft, wenn die Linsenvorrichtung von der Lichtaustrittsfläche der Mantelfläche einen Abstand von mehr als dem 0,6-fachen der radialen Erstreckung des Gehäuses aufweist. Es beträgt insbesondere ein (insbesondere radialer) Abstand der Linsenvorrichtung (insbesondere jedes Punktes der Linsenvorrichtung) von der Lichtaustrittsfläche (insbesondere jedes Punktes der Lichtaustrittsfläche) mehr als das 0,6-fache der radialen Erstreckung des Gehäuses. Ebenfalls ist es vorteilhaft, wenn eine radiale Erstreckung der Linsenvorrichtung im Wesentlichen das 0,4-fache bis 0,6-fache der radialen Erstreckung der Mantelfläche beträgt.In an advantageous embodiment, several circuit board elements are accommodated, which are essentially accommodated along an arc of a circle, preferably a circle, the center point of which preferably coincides with a center point of the lateral surface, with the light-emitting elements of the circuit board elements preferably intersecting on lines parallel to the height extension direction of the lateral surface are arranged in the arc of a circle. i.e. the printed circuit board elements are arranged in the recorded state such that the centers of the printed circuit board elements lie on a circular arc, preferably regularly spaced, or their central axes intersect in the direction of height extension of the lateral surface, so that each one lighting element of the printed circuit board elements on a Circular arc, preferably regularly spaced, or that the lines are parallel to the height extension direction of the lateral surface, on which a row of light-emitting elements are arranged, on a circuit board element on a circular arc, preferably regularly spaced. The lens device preferably has lens peaks, each of which influences the light of a light-emitting element or the light of a plurality of light-emitting elements of a printed circuit board element. In this case, the lens device itself can have essentially the same shape as the lateral surface, only with a smaller diameter, with lens peaks being arranged on its surface, each associated with a lighting element. Preferably, several narrow circuit board elements are arranged in a circle, each with a row of lighting elements arranged on a line parallel to the height direction of the lateral surface, so that the lighting elements shine radially outwards and their light is either scattered or collected only in the circumferential direction by a lens or additionally distributed or collected perpendicularly thereto. In this embodiment, in which several printed circuit board elements are to be accommodated, it is advantageous if the lens device has a distance of more than 0.6 times the radial extent of the housing from the light exit surface of the lateral surface. In particular, a (particularly radial) distance of the lens device (particularly each point of the lens device) from the light exit surface (particularly each point of the light exit surface) is more than 0.6 times the radial extension of the housing. It is also advantageous if a radial extent of the lens device is essentially 0.4 times to 0.6 times the radial extent of the lateral surface.

Es ist vorteilhaft, wenn die Linsenvorrichtung das von auf einer Linie parallel zur Höhenerstreckungsrichtung der Mantelfläche liegenden Leuchtelementen abgestrahlte Signallicht jeweils in Umfangsrichtung in einen im Wesentlichen für jede Reihe unterschiedlichen azimutalen, vorzugsweise genau an den nächsten angrenzenden, Winkelbereich fokussiert und vorzugsweise über diesen Winkelbereich vergleichmäßigt, wobei bevorzugt die Linsenvorrichtung das Signallicht in einen polaren Winkelbereich bündelt.It is advantageous if the lens device focuses the signal light emitted by light-emitting elements lying on a line parallel to the height extension direction of the lateral surface in the circumferential direction in a substantially different azimuthal angular range for each row, preferably precisely adjacent to the next, and preferably over equalizes this angular range, with the lens device preferably bundling the signal light into a polar angular range.

Gehäuse, die bei der Aufnahme der Leiterplattenelementen für mehrere Reihen an Leuchtelemente, die auf einer Linie im Wesentlichen parallel zur Höhenerstreckungsrichtung der Mantelfläche angeordnet sind, ausgelegt sind, benötigen durch die Linsenvorrichtung nicht notwendigerweise eine Vergleichmäßigung des Lichtes über die gesamte Umfangsrichtung der Lichtaustrittsfläche, sondern es können auch kleinere Sektoren, d. h. azimutale Winkelbereiche, der Lichtverteilung gewünscht sein, welche insbesondere nahtlos aneinander grenzen. Insbesondere für virtuelle Drehleuchten ist eine solche Anordnung mit mehreren nach Aufnahme der Leiterplatten im Wesentlichen auf einem Kreis(bogen) bzw. auf einem Zylinder(ausschnitt) angeordneten Leuchtelementen vorteilhaft. Dabei sollte die Linsenvorrichtung das Licht jedes Leuchtelements bzw. jeder Reihe von auf einer Linie parallel zur Höhenerstreckungsrichtung der Mantelfläche angeordneten Leuchtelementen jeweils in einem azimutalen Winkelbereich sammeln und vorzugsweise auch quer dazu, d. h. in einen polaren Winkelbereich, lichtsammelnde Funktion aufweisen. Bei virtuellen Drehleuchten werden die einzelnen Reihen von Leuchtelementen beispielsweise sequentiell angesteuert, um so einen visuellen Dreheffekt der Warnleuchte zu erzielen. Je mehr Reihen an Leuchtelementen vorhanden sind, umso enger können die Linsen das Licht der einzelnen Reihen in jeweilige aneinander angrenzende azimutale Winkelbereiche bündeln und umso intensiver bzw. gleichmäßiger wird der scheinbar rotierende Lichtstrahl. Auf einen Winkelbereich von 180° vergleichmäßigende Linsen würden nur einen geringen Dreheffekt zusammenbringen, die Bauweise mit nur einem beidseitig mit Leuchtelementen ausgestatteten Leiterplattenelement so gut wie gar keinen Dreheffekt. Für virtuelle Drehleuchten muss die elektrische Ansteuerung der Reihen von Leuchtelementen mit dem optischen Konzept der Linsenvorrichtung und des Gehäuses abgestimmt sein.Housings that are designed to accommodate the printed circuit board elements for several rows of lighting elements, which are arranged on a line essentially parallel to the height extension direction of the lateral surface, do not necessarily need the lens device to make the light more uniform over the entire circumferential direction of the light exit surface, but rather it can also smaller sectors, i. H. azimuthal angular ranges, the light distribution may be desired, which in particular border seamlessly. Such an arrangement with a plurality of lighting elements arranged essentially on a circle (arc) or on a cylinder (section) after receiving the printed circuit boards is particularly advantageous for virtual rotating lights. In this case, the lens device should collect the light of each light-emitting element or each row of light-emitting elements arranged on a line parallel to the height extension direction of the lateral surface in an azimuthal angular range and preferably also transversely thereto, i. H. in a polar angle range, have light-collecting function. In the case of virtual rotating lights, the individual rows of lighting elements are activated sequentially, for example, in order to achieve a visual rotating effect of the warning light. The more rows of light-emitting elements there are, the tighter the lenses can focus the light of the individual rows in respective adjoining azimuthal angular ranges and the more intense or even the apparently rotating light beam becomes. Lenses equalizing to an angular range of 180° would bring together only a small turning effect, the construction with only one printed circuit board element equipped with light elements on both sides almost no turning effect at all. For virtual rotating lights, the electrical control of the rows of lighting elements must be coordinated with the optical concept of the lens device and the housing.

Wie bereits im Zusammenhang mit bevorzugten Ausführungsformen beschrieben ist es vorteilhaft, wenn die Linsenvorrichtung das Signallicht in Umfangsrichtung über einen azimutalen Winkelbereich, der der Lichtaustrittsfläche der Mantelfläche entspricht, vergleichmäßigt, d. h. bündelt und/oder streut, und vorzugsweise das Signallicht in einen polaren Winkelbereich bündelt. Die Bündelung quer zur Umfangsrichtung, d. h. in einen polaren Winkelbereich, wird insbesondere benötigt, wenn das rundum abgestrahlte Licht insgesamt schräg nach unten abgestrahlt werden soll, z. B. bei hoher Anordnung der Signalleuchtvorrichtung, damit Licht nicht ungenutzt über alles hinweg ausgestrahlt wird.As already described in connection with preferred embodiments, it is advantageous if the lens device transmits the signal light in the circumferential direction over an azimuthal angular range, which corresponds to the light exit surface of the lateral surface, equalizes, ie bundles and/or scatters, and preferably bundles the signal light into a polar angle range. Bundling transversely to the circumferential direction, ie in a polar angular range, is required in particular if the light emitted all around is to be emitted obliquely downwards, e.g. B. with a high arrangement of the signal lighting device, so that light is not emitted unused over everything.

Es ist bevorzugt, dass die Lichtaustrittsfläche der Mantelfläche eine Streustruktur aufweist.It is preferred that the light exit surface of the lateral surface has a scattering structure.

Es ist vorteilhaft, dass die Linsenvorrichtung das zumindest eine von dem Gehäuse aufnehmbare Leiterplattenelement im aufgenommenen Zustand zumindest teilweise umschließt. Somit kann eine besonders gute Stabilität erreicht werden.It is advantageous that the lens device at least partially encloses the at least one circuit board element that can be accommodated by the housing in the accommodated state. A particularly good stability can thus be achieved.

Bezugnehmend auf die Leuchtsignalvorrichtung stellt die einstückige Ausführung von Linsenvorrichtung und Deckfläche eine besonders einfache Konstruktionsmöglichkeit dar, insbesondere wenn die Leuchtelemente linsenlos ausgeführt sind. Bezugnehmend auf das Verfahren zur Herstellung eines Gehäuses zur Aufnahme zumindest eines Leiterplattenelements mit zumindest einem Leuchtelement zur Abgabe eines Signallichtes stellt dies eine besonders kostengünstige und einfache Herstellungsmethode dar.With regard to the light signal device, the one-piece design of the lens device and cover surface represents a particularly simple design option, in particular if the light-emitting elements are designed without lenses. Referring to the method for manufacturing a housing for accommodating at least one printed circuit board element with at least one lighting element for emitting a signal light, this represents a particularly cost-effective and simple manufacturing method.

Fig. 1a zeigt eine bevorzugte Ausführungsform des erfindungsgemäßen Gehäuses 1 in einer Ansicht von schräg unten, Fig. 1b in einer Ansicht von genau unter, Fig. 1c eine Ansicht im Schnitt F-F aus Fig. 1b und Fig. 1d eine Ansicht im Schnitt G-G aus Fig. 1b, wobei die Deckfläche 5 als oben in Bezug auf das Gehäuse 1 definiert wird. Das Gehäuse weist eine Mantelfläche 3 auf, die die Form der Mantelfläche eines Zylinders hat. Die Mantelfläche 3 wird nach oben von der Deckfläche 5 begrenzt. Die Mantelfläche 3 weist eine Streustruktur 6 auf, die im Wesentlichen die Lichtaustrittsfläche 4 bildet, die in der vorliegenden Ausführungsform den gesamten Umfang der Mantelfläche 3 umläuft. Die Linsenvorrichtung 2 ist einstückig mit der Deckfläche 5 ausgebildet. Die Linsenvorrichtung 2 wird dabei von zwei Profil-Linsenstäben 7 gebildet, die eine Nut 8 zur Aufnahme eines Leiterplattenelements 9 (nicht abgebildet, vgl. Fig. 1e bis 1h) bilden. Weiters weisen die Profil-Linsenstäbe 7 jeweils eine Nut 8 zur Aufnahme einer Reihe von Leuchtelemente des Leiterplattenelements 9 auf, die im aufgenommenen Zustand entlang jeweils einer Linie parallel zur Höhenerstreckungsrichtung der Mantelfläche 3 auf beiden Seiten des Leiterplattenelements 9 angeordnet sind. Die Profil-Linsenstäbe 7 vergleichmäßigen das Licht jeweils über einen azimutalen Winkelbereich von 180°, sodass insgesamt die Lichtaustrittsfläche 4 über den gesamten Umfang möglichst gleichmäßig ausgeleuchtet wird. Um die Verteilung des Lichts über den gesamten Umfang der Lichtaustrittsfläche 4 zu ermöglichen, ist ein räumlicher Abstand zwischen Lichtaustrittsfläche 4 und Linsenvorrichtung 7 nötig. Die Linsenvorrichtung 2 ist in dieser Ausführungsform unmittelbar entformbar ausgeführt. Weiters weist das Gehäuse (wie auch in den Ausführungsformen der folgenden Figuren) Vorrichtungen zur Bajonettverbindung mit einem weiteren Gehäuse auf. Die Höhenerstreckungsrichtung der Mantelfläche 3 ist in Fig. 1b also normal zur Bildebene, wohingegen sie in Fig. 1c und 1d genau vertikal ist. Der azimutale Winkel(bereich) liegt dementsprechend in der Bildebene der Fig. 1b, während der polare Winkel(bereich) in der Bildebene der Fig. 1c und 1d liegt. Fig. 1a shows a preferred embodiment of the housing 1 according to the invention in an oblique view from below, Fig. 1b in a view from right below, 1c a view in section FF Fig. 1b and Fig. 1d a view in section GG Fig. 1b , where the top surface 5 is defined as being at the top with respect to the housing 1. The housing has a lateral surface 3 which has the shape of the lateral surface of a cylinder. The outer surface 3 is delimited at the top by the top surface 5 . The lateral surface 3 has a scattering structure 6, which essentially forms the light exit surface 4, which runs around the entire circumference of the lateral surface 3 in the present embodiment. The lens device 2 is formed in one piece with the top surface 5 . The lens device 2 is formed by two profile lens rods 7, which have a groove 8 for receiving a printed circuit board element 9 (not shown, cf. Figures 1e to 1h ) form. Furthermore, the profile lens rods 7 each have a groove 8 for accommodating a row of light-emitting elements of the printed circuit board element 9, which are arranged in the mounted state along a line parallel to the height extension direction of the lateral surface 3 on both sides of the printed circuit board element 9. The profile lens rods 7 equalize the light over an azimuthal angular range of 180°, so that overall the light exit surface 4 is illuminated as uniformly as possible over the entire circumference. In order to enable the light to be distributed over the entire circumference of the light exit surface 4 , a spatial distance between the light exit surface 4 and the lens device 7 is necessary. In this embodiment, the lens device 2 is designed so that it can be removed from the mold immediately. Furthermore, the housing (as in the embodiments of the following figures) has devices for a bayonet connection to another housing. The height direction of lateral surface 3 is in Fig. 1b i.e. normal to the image plane, whereas they are in Figures 1c and 1d is exactly vertical. The azimuthal angle (range) is accordingly in the image plane Fig. 1b , while the polar angle (area) in the image plane of Figures 1c and 1d lies.

Die Fig. 1e bis 1h zeigen dieselbe Ausführungsform von den jeweils entsprechenden Ansichten wie die Fig. 1a bis 1d, wobei das Gehäuse 1 zusätzlich das Leiterplattenelement 9 aufweist.the Figures 1e to 1h show the same embodiment from the respective corresponding views as FIG Figures 1a to 1d , wherein the housing 1 additionally has the printed circuit board element 9 .

Fig. 2a zeigt eine weitere bevorzugte Ausführungsform des Gehäuses 1 in einer Ansicht von schräg unten und Fig. 2b dieselbe Ausführungsform in einer Ansicht von unten, wobei die Mantelfläche 3 die Form der Mantelfläche eines Halbzylinders aufweist. Die im Querschnitt runde Fläche der Mantelfläche über einen Teil der Höhe der Mantelfläche bildet dabei die Lichtaustrittsfläche 4, die eine Streustruktur 6 aufweist. Die Linsenvorrichtung 2, die einstückig mit der Deckfläche 5 ausgebildet ist, weist einen Profil-Linsenstab 7 auf, der zusammen mit der planen Fläche der Mantelfläche 3 eine Nut 8 zur Aufnahme eines Leiterplattenelements 9 (nicht abgebildet) darstellt, wobei das Leiterplattenelement 9 ein Reihe von Leuchtelementen auf der im aufgenommenen Zustand der Lichtaustrittsfläche 4 zugewandten Seite aufweist, die auf einer Linie parallel zur Höhenerstreckungsrichtung der Mantelfläche 3 angeordnet sind und für die ebenfalls eine Nut 8 in der Linsenvorrichtung 2 vorgesehen ist. Der Profil-Linsenstab 7 vergleichmäßigt das Licht über einen azimutalen Winkelbereich von 180°, der der Lichtaustrittsfläche 4 entspricht. Die Streustruktur 6 streut das Licht von jeweiligen Stellen an der Lichtaustrittsfläche 4 jeweils in einen Bereich von etwa 180° weg von Lichtaustrittsfläche 4 gemessen in der Bildebene der Fig. 2b (d. h. derselben Ebene wie der azimutale Winkel). Der Profil-Linsenstab 7 und damit die Linsenvorrichtung 2 sind wiederum unmittelbar entformbar ausgebildet. Figure 2a shows a further preferred embodiment of the housing 1 in a view obliquely from below and Figure 2b the same embodiment in a view from below, the lateral surface 3 having the shape of the lateral surface of a semi-cylinder. The surface of the lateral surface, which is round in cross section, forms the light exit surface 4 over part of the height of the lateral surface, which has a scattering structure 6 . The lens device 2, which is formed in one piece with the top surface 5, has a profile lens rod 7 which, together with the flat surface of the lateral surface 3, forms a groove 8 for receiving a circuit board element 9 (not shown), the circuit board element 9 has a row of lighting elements on the side facing the light exit surface 4 in the recorded state, which are arranged on a line parallel to the height extension direction of the lateral surface 3 and for which a groove 8 is also provided in the lens device 2. The profile lens rod 7 equalizes the light over an azimuthal angular range of 180°, which corresponds to the light exit surface 4 . The scattering structure 6 scatters the light from respective points on the light exit surface 4 in an area of approximately 180° away from the light exit surface 4 measured in the image plane of FIG Figure 2b (ie same plane as the azimuthal angle). The profile lens rod 7 and thus the lens device 2 are in turn designed so that they can be removed from the mold immediately.

Fig. 3a zeigt eine vorteilhafte Ausführungsform der Leuchtsignalvorrichtung 11 mit dem Gehäuse 1 mit aufgenommenen Leiterplattenelementen 9 in einer Ansicht von schräg unten, Fig. 3b die dazugehörige Linsenvorrichtung im Detail von schräg unten, Fig. 3c die Ausführungsform von unten und Fig. 3d die Ausführungsform in einer Ansicht im Schnitt F-F in Fig. 3c. Die Mantelfläche 3 des Gehäuses 1 ist zylinderförmig ausgebildet und weist eine den gesamten Umfang und einen Teil der Höhe umfassende Lichtaustrittsfläche 4 mit einer Streustruktur 6 auf, wobei die Mantelfläche 3 nach oben im Wesentlichen von der Deckfläche 5 begrenzt wird. Die Linsenvorrichtung 2 ist ebenfalls im Wesentlichen zylinderförmig ausgebildet, wobei die Linsenvorrichtung 2 sechs Nuten 8 aufweist, in die jeweils ein Leiterplattenelement 9 aufgenommen ist. Jedes Leiterplattenelement 9 weist drei Leuchtelemente (nicht abgebildet) auf, die jeweils auf einer Linie parallel zur Höhenerstreckungsrichtung der Mantelfläche 3 angeordnet sind, wobei die Nuten 8 zur Aufnahme der Leiterplatten 9 jeweils weitere Nuten 8 zur Aufnahme der auf einer Linie angeordneten Leuchtelemente aufweisen. Jedem Leuchtelement zugeordnet weist die Linsenvorrichtung 2 eine Linsenkuppe 10 auf. Die Linsenkuppen 10 können beispielsweise so ausgeformt sein, dass das von einem Leuchtelement (bzw. einer auf einer Linie angeordneten Reihe von Leuchtelementen) ausgestrahlte Licht in aneinander angrenzende azimutale Winkelbereiche von 60° (z. B. bei Verwendung als virtuelle Drehleuchte) oder überschneidende Winkelbereiche von 180° gebündelt und vergleichmäßigt wird. Weiters bündeln die Linsenkuppen 10 das ausgestrahlte Licht in einem polaren Winkelbereich, der beispielsweise ein Winkelbereich von wenigen Grad, beispielsweise 15 Grad, über und wenige Grad, beispielsweise 15 Grad, unter der Bildebene in Fig. 3c sein kann. Wenn die Leuchtsignalvorrichtung aufweisend das Gehäuse an einem hohen Ort angebracht wird, kann der polare Winkelbereich auch zwischen der Bildebene oder wenige Grad, beispielsweise 5 Grad, unter der Bildebene in Fig. 3c und einigen Grad, beispielsweise 35 Grad, darunter sein. Figure 3a shows an advantageous embodiment of the light signaling device 11 with the housing 1 with printed circuit board elements 9 accommodated in a view obliquely from below, Figure 3b the associated lens device in detail from diagonally below, 3c the embodiment from below and 3d the embodiment in a view in section FF in 3c . The lateral surface 3 of the housing 1 is cylindrical and has a light exit surface 4 that encompasses the entire circumference and part of the height and has a diffusing structure 6 , the lateral surface 3 being delimited at the top essentially by the top surface 5 . The lens device 2 is also essentially cylindrical, with the lens device 2 having six grooves 8 in each of which a printed circuit board element 9 is accommodated. Each printed circuit board element 9 has three light-emitting elements (not shown), which are each arranged on a line parallel to the direction in which the lateral surface 3 extends in height, with the grooves 8 for receiving the printed circuit boards 9 each having further grooves 8 for receiving the light-emitting elements arranged in a line. The lens device 2 has a lens cap 10 assigned to each light-emitting element. The lens caps 10 can, for example, be shaped in such a way that the light emitted by a lighting element (or a row of lighting elements arranged in a line) radiates into adjacent azimuthal angular ranges of 60° (e.g. when used as a virtual rotating light) or overlapping angular ranges of 180° bundled and equalized becomes. Furthermore, the lens caps 10 bundle the emitted light in a polar angular range, which is, for example, an angular range of a few degrees, for example 15 degrees, above and a few degrees, for example 15 degrees, below the image plane in 3c can be. When the flared signaling device comprising the housing is mounted at a high location, the polar angle range can also be between the image plane or a few degrees, e.g. 5 degrees, below the image plane in 3c and a few degrees, for example 35 degrees, below.

Die in den Figuren dargestellten und in deren Zusammenhang beschrieben Ausführungsbeispiele dienen lediglich der Veranschaulichung der Erfindung und sind für diese nicht beschränkend.The exemplary embodiments shown in the figures and described in connection with them only serve to illustrate the invention and are not restrictive of it.
