Definitions
- the present invention relates to a luminaire for a light band.
- the present invention also relates to a device carrier for such a luminaire.
- a light band usually a linear juxtaposition of several lights is referred to, within the light band several lights have a common power supply and are controlled together.
- a luminaire for such a light band usually has a support profile for ceiling and wall mounting and a device carrier, which can be fastened to the support profile, preferably releasably, and which carries at least one socket for a light source.
- the functional separation between the support profile and equipment carrier can be advantageously implemented so that the support profile can be mounted without attached equipment carrier on the wall or ceiling.
- the device carrier can also be removed from the support profile, such that the support profile remains on the wall or ceiling.
- Such a version for example, have a foot which is inserted into an opening of the device carrier and fixed to an opening edge enclosing the opening, z. B. locked so can be.
- the device carrier can be designed, for example, as a sheet metal part, with comparatively small plate thicknesses being used to achieve low production costs and a low component weight.
- An introduced into the device carrier thus prepared, in particular punched, opening for receiving the socket foot has an opening edge, which has a comparatively low rigidity.
- a transverse load of the socket can therefore be the case that the catch between the foot and opening edge loosened and in extreme cases also solved, so that the foot out of the opening move and the socket can move relative to the equipment rack.
- Such a transverse load of the Socket can occur, for example, when a fluorescent tube is used as the light source, which is held at its longitudinal ends in two such versions.
- the fluorescent tube enveloping and also held in the sockets thermowell can extend thermally induced and thereby introduce lateral forces in the sockets. These transverse forces may be sufficient to cancel the latching, wherein in extreme cases, the respective foot in the associated opening can bend so far that the respective version can move away from the equipment rack. There is a risk that the respective bulb in the version of the respective electrical contact dissolves and is energized in the sequence.
- a recessed luminaire whose device carrier can be installed by means of appropriate fasteners directly into a cover-side or wandseitiege installation niche.
- the device carrier has centrally to the stiffening on a profile education, which defines a central support area, are formed in the openings for attaching sockets.
- the invention is concerned with the problem of providing an improved embodiment for a luminaire of the type mentioned, which is characterized in particular by an increased reliability of the fixation between the socket and device carrier.
- the invention is based on the general idea to form the opening edge limiting opening edge on a support portion of the device carrier, the surrounds the opening and which is arranged offset relative to a region of the device carrier adjacent thereto in the longitudinal direction of the luminaire.
- the opening, opening edge and support area lie in an opening plane or support area plane which runs parallel to a plane (device support plane) in which the area of the equipment support adjacent to the support area lies.
- the support area is offset from the adjoining area of the equipment carrier offset perpendicular to the opening plane. This offset creates a step profile in a section through the equipment carrier in the area of the opening, which leads to an intensive stiffening of the equipment carrier in the carrying area.
- the support region has the opening edge, thereby also the opening edge is stabilized, whereby the connection, in particular a catch, receives a higher pull-out strength between foot and opening edge. It is clear that the support area is not a separate component, but an integral part of the device carrier.
- the support profile is designed so that it can be mounted without attached equipment carrier to the respective ceiling or wall.
- the assembly is simplified, since so the first compared to the equipment carrier light support profile can be easily mounted on the wall or ceiling, while in comparison to the support profile heavy equipment carrier with attached devices, e.g. Bulbs, then also can be easily attached to the support profile.
- This is particularly advantageous when mounting the luminaire to a ceiling, since this is to be performed by the respective fitter as an overhead assembly, in which any weight reduction is of great advantage.
- the respective support region is formed by deformation on the equipment carrier.
- the support area is integrally formed on the equipment carrier, so no relative to the equipment carrier separate component.
- Such deformation generates in the region of the above-mentioned stage, which forms the transition between the support region and the region adjacent thereto, a material hardening or stiffening, which leads to the stiffening of the support region.
- an embodiment in which the respective support region is formed by embossing on the equipment carrier is particularly advantageous.
- An embossing corresponds to a deep drawing for producing a step for stiffening purposes.
- the support portion is integrally formed on the equipment carrier and is therefore not a separate component with respect to the device carrier.
- Such embossing can be realized particularly easily by an embossing process with a corresponding embossing punch.
- a correspondingly modified cutting punch can be used for the stamping, with the aid of which the respective opening on the equipment carrier is punched out.
- both the opening edge and the embossment can be produced in a single processing step.
- the support area may lie in a support area plane which extends parallel to and at a distance from a device support plane in which the area of the equipment support adjoining the support area lies. This results in particularly easy to produce geometric structures, which favors an inexpensive production of the equipment carrier and thus the lamp.
- the region of the equipment carrier adjacent to the support region surrounds or encloses the support region in an annular manner.
- a configuration can be easily produced by means of an embossing which generates the supporting area in the device carrier in the form of a raised area or depression, which in the device carrier Longitudinal section and / or cross section over two, preferably symmetrical, steps merges into the area adjacent to the support area.
- the respective survey or depression is expedient just designed.
- At least one edge portion of the opening edge may be angled away from the support area.
- the angling of the edge portion of the opening edge from the support area results in a significant stiffening of the support area, which mainly affects an increased rigidity of the opening edge in said edge portion.
- the opening edge in the region of the respective edge section thereby also receives an increased material thickness, which is measured perpendicular to the opening plane. This also leads to a stiffening of the support area in the respective edge portion. At the same time this simplifies a positive locking between foot and opening edge.
- the respective edge portion by about 90 ° with respect to a support area level, in which the support area is located, be angled.
- By bending by about 90 ° results in a maximum wall thickness for the opening edge in the respective edge portion, which simplifies a high-quality locking.

- at least those edge portions are angled, which extend perpendicular to a longitudinal direction of the device carrier.
- the respective edge section may be angled away from the support area, counter to a direction in which the support area is offset from the adjacent area.

With respect to the support profile of the support portion may be offset outwards, while the respective edge portion is angled inward. Thus, a sharp contour can be avoided on the side facing away from the support profile outside of the equipment carrier.
- the foot has at least one latching element, which engages behind the respective angled edge section for latching the foot with the opening edge. This results in a positive connection between the angled edge portion and locking element, whereby particularly high extraction forces can be realized.

Abstract
Description
Die vorliegende Erfindung betrifft eine Leuchte für ein Lichtband. Die vorliegende Erfindung betrifft außerdem einen Geräteträger für eine derartige Leuchte.The present invention relates to a luminaire for a light band. The present invention also relates to a device carrier for such a luminaire.
Als Lichtband wird üblicherweise eine geradlinige Aneinanderreihung mehrerer Leuchten bezeichnet, wobei innerhalb des Lichtbands mehrere Leuchten eine gemeinsame Stromversorgung aufweisen und gemeinsam angesteuert werden.As a light band usually a linear juxtaposition of several lights is referred to, within the light band several lights have a common power supply and are controlled together.
Eine Leuchte für ein derartiges Lichtband weist üblicherweise ein Tragprofil zur Decken- und Wandmontage sowie einen Geräteträger auf, der am Tragprofil, vorzugsweise lösbar, befestigt werden kann und der zumindest eine Fassung für ein Leuchtmittel trägt. Dabei kann die funktionale Trennung zwischen Tragprofil und Geräteträger zweckmäßig so realisiert sein, dass das Tragprofil auch ohne daran angebrachten Geräteträger an der Wand oder Decke montiert werden kann. Insbesondere lässt sich der Geräteträger auch vom Tragprofil entfernen, derart, dass das Tragprofil an der Wand bzw. Decke verbleibt. Eine derartige Fassung kann beispielsweise einen Fuß aufweisen, der in eine Öffnung des Geräteträgers eingesteckt und an einem die Öffnung einfassenden Öffnungsrand festgelegt, z. B. damit verrastet, werden kann. Der Geräteträger kann beispielsweise als Blechformteil konzipiert sein, wobei zur Erzielung niedriger Herstellungskosten und eines geringen Bauteilsgewicht vergleichsweise geringe Blechstärken verwendet werden. Eine in den so hergestellten Geräteträger eingebrachte, insbesondere eingestanzte, Öffnung zur Aufnahme des Fassungsfußes besitzt einen Öffnungsrand, der eine vergleichsweise geringe Steifigkeit besitzt. Bei einer Querbelastung der Fassung kann daher der Fall auftreten, dass die Verrastung zwischen Fuß und Öffnungsrand gelockert und im Extremfall auch gelöst wird, so dass sich der Fuß aus der Öffnung herausbewegen und sich die Fassung relativ zum Geräteträger bewegen kann. Eine derartige Querbelastung der Fassung kann beispielsweise dann auftreten, wenn als Leuchtmittel eine Leuchtstoffröhre verwendet wird, die an ihren Längsenden in zwei derartigen Fassungen gehalten ist. Die Leuchtstoffröhre oder ein bei bestimmten Anwendungen und Einbausituationen vorgeschriebenes, die Leuchtstoffröhre umhüllendes und ebenfalls in den Fassungen gehaltenes Schutzrohr kann sich thermisch bedingt ausdehnen und dadurch Querkräfte in die Fassungen einleiten. Diese Querkräfte können ausreichen, die Verrastung aufzuheben, wobei im Extremfall sich der jeweilige Fuß in der zugehörigen Öffnung soweit verbiegen kann, dass sich die jeweilige Fassung vom Geräteträger entfernen kann. Dabei besteht die Gefahr, dass sich auch das jeweilige Leuchtmittel in der Fassung vom jeweiligen elektrischen Kontakt löst und in der Folge unbestromt ist.A luminaire for such a light band usually has a support profile for ceiling and wall mounting and a device carrier, which can be fastened to the support profile, preferably releasably, and which carries at least one socket for a light source. In this case, the functional separation between the support profile and equipment carrier can be advantageously implemented so that the support profile can be mounted without attached equipment carrier on the wall or ceiling. In particular, the device carrier can also be removed from the support profile, such that the support profile remains on the wall or ceiling. Such a version, for example, have a foot which is inserted into an opening of the device carrier and fixed to an opening edge enclosing the opening, z. B. locked so can be. The device carrier can be designed, for example, as a sheet metal part, with comparatively small plate thicknesses being used to achieve low production costs and a low component weight. An introduced into the device carrier thus prepared, in particular punched, opening for receiving the socket foot has an opening edge, which has a comparatively low rigidity. In a transverse load of the socket can therefore be the case that the catch between the foot and opening edge loosened and in extreme cases also solved, so that the foot out of the opening move and the socket can move relative to the equipment rack. Such a transverse load of the Socket can occur, for example, when a fluorescent tube is used as the light source, which is held at its longitudinal ends in two such versions. The fluorescent tube or a prescribed in certain applications and installation situations, the fluorescent tube enveloping and also held in the sockets thermowell can extend thermally induced and thereby introduce lateral forces in the sockets. These transverse forces may be sufficient to cancel the latching, wherein in extreme cases, the respective foot in the associated opening can bend so far that the respective version can move away from the equipment rack. There is a risk that the respective bulb in the version of the respective electrical contact dissolves and is energized in the sequence.
Aus der
Hier setzt die vorliegende Erfindung an. Die Erfindung beschäftigt sich mit dem Problem, für eine Leuchte der eingangs genannten Art eine verbesserte Ausführungsform anzugeben, die sich insbesondere durch eine erhöhte Zuverlässigkeit der Fixierung zwischen Fassung und Geräteträger auszeichnet.This is where the present invention begins. The invention is concerned with the problem of providing an improved embodiment for a luminaire of the type mentioned, which is characterized in particular by an increased reliability of the fixation between the socket and device carrier.
Dieses Problem wird bei der vorliegenden Erfindung insbesondere durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved in the present invention, in particular by the subject of the independent claim. Advantageous embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, den die Öffnung begrenzenden Öffnungsrand an einem Tragbereich des Geräteträgers auszubilden, der die Öffnung einfasst und der gegenüber einem in der Längsrichtung der Leuchte daran angrenzenden Bereich des Geräteträgers versetzt angeordnet ist. Beispielsweise liegen Öffnung, Öffnungsrand und Tragbereich in einer Öffnungsebene oder Tragbereichsebene, die parallel zu einer Ebene (Geräteträgerebene) beabstandet verläuft, in welcher der an den Tragbereich angrenzenden Bereich des Geräteträgers liegt. Mit anderen Worten, der Tragbereich ist gegenüber dem daran angrenzenden Bereich des Geräteträgers senkrecht zur Öffnungsebene versetzt angeordnet. Durch diesen Versatz entsteht in einem Schnitt durch den Geräteträger im Bereich der Öffnung ein Stufenprofil, was zu einer intensiven Aussteifung des Geräteträgers im Tragbereich führt. Da der Tragbereich den Öffnungsrand aufweist, wird dadurch auch der Öffnungsrand stabilisiert, wodurch die Verbindung, insbesondere eine Verrastung, zwischen Fuß und Öffnungsrand eine höhere Auszugsfestigkeit erhält. Es ist klar, dass der Tragbereich kein separates Bauteil, sondern ein integraler Bestandteil des Geräteträgers ist.The invention is based on the general idea to form the opening edge limiting opening edge on a support portion of the device carrier, the surrounds the opening and which is arranged offset relative to a region of the device carrier adjacent thereto in the longitudinal direction of the luminaire. For example, the opening, opening edge and support area lie in an opening plane or support area plane which runs parallel to a plane (device support plane) in which the area of the equipment support adjacent to the support area lies. In other words, the support area is offset from the adjoining area of the equipment carrier offset perpendicular to the opening plane. This offset creates a step profile in a section through the equipment carrier in the area of the opening, which leads to an intensive stiffening of the equipment carrier in the carrying area. Since the support region has the opening edge, thereby also the opening edge is stabilized, whereby the connection, in particular a catch, receives a higher pull-out strength between foot and opening edge. It is clear that the support area is not a separate component, but an integral part of the device carrier.
Besonder zweckmäßig ist hierbei eine Ausführungsform, bei welcher das Tragprofil so ausgestaltet ist, dass es ohne daran angebrachten Geräteträger an der jeweiligen Decke oder Wand montiert werden kann. Die Montage vereinfacht sich, da so zuerst das im Vergleich zum Geräteträger leichte Tragprofil einfach an der Wand oder Decke montiert werden kann, während der im Vergleich zum Tragprofil schwere Geräteträger mit daran angebrachten Geräten, z.B. Leuchtmitteln, dann ebenfalls einfach an das Tragprofil angebaut werden kann. Dies ist insbesondere bei der Montage der Leuchte an einer Decke besonders vorteilhaft, da dies vom jeweiligen Monteur als Überkopfmontage auszuführen ist, bei der jede Gewichtsreduzierung von großem Vorteil ist.Particularly useful here is an embodiment in which the support profile is designed so that it can be mounted without attached equipment carrier to the respective ceiling or wall. The assembly is simplified, since so the first compared to the equipment carrier light support profile can be easily mounted on the wall or ceiling, while in comparison to the support profile heavy equipment carrier with attached devices, e.g. Bulbs, then also can be easily attached to the support profile. This is particularly advantageous when mounting the luminaire to a ceiling, since this is to be performed by the respective fitter as an overhead assembly, in which any weight reduction is of great advantage.
Besonders vorteilhaft ist eine Ausführungsform, bei welcher der jeweilige Tragbereich durch Umformung am Geräteträger ausgebildet ist. Hierbei ist der Tragbereich integral am Geräteträger ausgeformt, also kein bezüglich des Geräteträgers separates Bauteil. Eine derartige Umformung erzeugt im Bereich der vorstehend genannten Stufe, die den Übergang zwischen Tragbereich und daran angrenzenden Bereich bildet, eine Materialverfestigung bzw. Versteifung, die zur Aussteifung des Tragbereichs führt.Particularly advantageous is an embodiment in which the respective support region is formed by deformation on the equipment carrier. Here, the support area is integrally formed on the equipment carrier, so no relative to the equipment carrier separate component. Such deformation generates in the region of the above-mentioned stage, which forms the transition between the support region and the region adjacent thereto, a material hardening or stiffening, which leads to the stiffening of the support region.
Besonders vorteilhaft ist dabei eine Ausführungsform, bei welcher der jeweilige Tragbereich durch eine Verprägung am Geräteträger ausgebildet ist. Eine Verprägung entspricht dabei einem Tiefziehen zum Herstellen einer Stufe zu Versteifungszwecken. Auch hierbei ist der Tragbereich integral am Geräteträger ausgeformt und ist folglich kein bezüglich des Geräteträgers separates Bauteil. Eine derartige Verprägung kann besonders einfach durch einen Prägevorgang mit einem entsprechenden Prägestempel realisiert werden. Beispielsweise kann für die Verprägung ein entsprechend modifizierter Schneidstempel verwendet werden, mit dessen Hilfe die jeweilige Öffnung am Geräteträger ausgestanzt wird. So können in einem einzigen Verarbeitungsschritt sowohl der Öffnungsrand als auch die Verprägung hergestellt werden.In this case, an embodiment in which the respective support region is formed by embossing on the equipment carrier is particularly advantageous. An embossing corresponds to a deep drawing for producing a step for stiffening purposes. Again, the support portion is integrally formed on the equipment carrier and is therefore not a separate component with respect to the device carrier. Such embossing can be realized particularly easily by an embossing process with a corresponding embossing punch. For example, a correspondingly modified cutting punch can be used for the stamping, with the aid of which the respective opening on the equipment carrier is punched out. Thus, both the opening edge and the embossment can be produced in a single processing step.
Zweckmäßig kann vorgesehen sein, dass der Tragbereich in einer Tragbereichsebene liegt, die sich parallel und beabstandet zu einer Geräteträgerebene erstreckt, in welcher der an den Tragbereich angrenzende Bereich des Geräteträgers liegt. Hierdurch ergeben sich besonders einfach herstellbare geometrische Strukturen, was eine preiswerte Herstellung des Geräteträgers und somit der Leuchte begünstigt.It may be expedient to provide for the support area to lie in a support area plane which extends parallel to and at a distance from a device support plane in which the area of the equipment support adjoining the support area lies. This results in particularly easy to produce geometric structures, which favors an inexpensive production of the equipment carrier and thus the lamp.
Bei einer anderen vorteilhaften Ausführungsform kann vorgesehen sein, dass der an den Tragbereich angrenzende Bereich des Geräteträgers den Tragbereich ringförmig geschlossen umfasst bzw. einfasst. Insbesondere lässt sich eine solche Konfiguration mittels einer Verprägung einfach herstellen, die im Geräteträger den Tragbereich in Form einer Erhebung oder Vertiefung erzeugt, die im Längsschnitt und/oder Querschnitt über zwei, vorzugsweise symmetrische, Stufen in den an den Tragbereich angrenzenden Bereich übergeht. Die jeweilige Erhebung bzw. Vertiefung ist zweckmäßig eben ausgestaltet.In another advantageous embodiment, it can be provided that the region of the equipment carrier adjacent to the support region surrounds or encloses the support region in an annular manner. In particular, such a configuration can be easily produced by means of an embossing which generates the supporting area in the device carrier in the form of a raised area or depression, which in the device carrier Longitudinal section and / or cross section over two, preferably symmetrical, steps merges into the area adjacent to the support area. The respective survey or depression is expedient just designed.
Bei einer anderen vorteilhaften Ausführungsform kann zumindest ein Randabschnitt des Öffnungsrands vom Tragbereich abgewinkelt sein. Durch die Abwinklung des Randabschnitts des Öffnungsrands vom Tragbereich ergibt sich zum einen eine signifikante Aussteifung des Tragbereichs, die sich vor allem auf eine erhöhte Steifigkeit des Öffnungsrands in besagtem Randabschnitt auswirkt. Zum anderen erhält der Öffnungsrand im Bereich des jeweiligen Randabschnitts dadurch auch eine vergrößerte Materialstärke, die senkrecht zur Öffnungsebene gemessen ist. Auch dies führt zu einer Aussteifung des Tragbereichs im jeweiligen Randabschnitt. Gleichzeitig vereinfacht sich dadurch eine formschlüssige Verrastung zwischen Fuß und Öffnungsrand.In another advantageous embodiment, at least one edge portion of the opening edge may be angled away from the support area. By the angling of the edge portion of the opening edge from the support area results in a significant stiffening of the support area, which mainly affects an increased rigidity of the opening edge in said edge portion. On the other hand, the opening edge in the region of the respective edge section thereby also receives an increased material thickness, which is measured perpendicular to the opening plane. This also leads to a stiffening of the support area in the respective edge portion. At the same time this simplifies a positive locking between foot and opening edge.
Bei einer vorteilhaften Weiterbildung kann der jeweilige Randabschnitt um etwa 90° gegenüber einer Tragbereichsebene, in welcher der Tragbereich liegt, abgewinkelt sein. Durch die Abwinklung um etwa 90° ergibt sich eine maximale Wandstärke für den Öffnungsrand im jeweiligen Randabschnitt, was eine hochwertige Verrastung vereinfacht. Gleichzeitig wird dadurch die Biegesteifigkeit des Öffnungsrand im jeweiligen Randabschnitt optimiert.In an advantageous development of the respective edge portion by about 90 ° with respect to a support area level, in which the support area is located, be angled. By bending by about 90 ° results in a maximum wall thickness for the opening edge in the respective edge portion, which simplifies a high-quality locking. At the same time, the bending stiffness of the opening edge in the respective edge section is thereby optimized.
Zweckmäßig kann der jeweilige abgewinkelte Randabschnitt geradlinig sein.Suitably, the respective angled edge portion may be rectilinear.
Gemäß einer bevorzugten Ausführungsform sind zumindest zwei einander gegenüberliegende abgewinkelte Randabschnitte vorgesehen, was zur Erzielung einer symmetrischen Verrastung von Vorteil ist. Zweckmäßig sind zumindest diejenigen Randabschnitte abgewinkelt, die sich senkrecht zu einer Längsrichtung des Geräteträgers erstrecken.According to a preferred embodiment, at least two opposing angled edge portions are provided, which is advantageous for achieving a symmetrical locking. Suitably, at least those edge portions are angled, which extend perpendicular to a longitudinal direction of the device carrier.
Bei einer anderen Ausführungsform kann der jeweilige Randabschnitt entgegen einer Richtung, in welcher der Tragbereich gegenüber dem angrenzenden Bereich versetzt ist, vom Tragbereich abgewinkelt sein. Auf diese Weise baut der abgewinkelte Randabschnitt nicht zusätzlich auf den Tragbereich auf, wodurch die Ausgestaltung des Geräteträgers im Bereich der Öffnung kompakt und flach bleibt. Bezüglich des Tragprofils kann der Tragbereich nach außen versetzt sein, während der jeweilige Randabschnitt nach innen abgewinkelt ist. Somit kann an der vom Tragprofil abgewandten Außenseite des Geräteträgers eine scharfe Kontur vermieden werden.In another embodiment, the respective edge section may be angled away from the support area, counter to a direction in which the support area is offset from the adjacent area. In this way, the angled edge portion does not additionally build on the support area, whereby the design of the device carrier in the region of the opening remains compact and flat. With respect to the support profile of the support portion may be offset outwards, while the respective edge portion is angled inward. Thus, a sharp contour can be avoided on the side facing away from the support profile outside of the equipment carrier.
Gemäß einer bevorzugten Ausführungsform weist der Fuß wenigstens ein Rastelement auf, das zum Verrasten des Fußes mit dem Öffnungsrand den jeweiligen abgewinkelten Randabschnitt hintergreift. Hierdurch ergibt sich ein Formschluss zwischen abgewinkeltem Randabschnitt und Rastelement, wodurch besonders hohe Auszugskräfte realisierbar sind.According to a preferred embodiment, the foot has at least one latching element, which engages behind the respective angled edge section for latching the foot with the opening edge. This results in a positive connection between the angled edge portion and locking element, whereby particularly high extraction forces can be realized.
Bei einer anderen vorteilhaften Ausführungsform kann der Geräteträger ein Blechformteil sein, das aus einem Blechkörper mit einer Wandstärke hergestellt ist. Derartige Blechformteile lassen sich besonders einfach und preiswert herstellen.In another advantageous embodiment of the device carrier may be a sheet metal part, which is made of a sheet metal body with a wall thickness. Such sheet metal parts can be produced in a particularly simple and inexpensive.
Zweckmäßig kann nun der jeweilige abgewinkelte Randabschnitt um eine Höhe vom Tragbereich abstehen, die etwa gleich groß ist wie die Wandstärke des Blechkörpers, aus dem der Geräteträger hergestellt ist. Mit anderen Worten, der abgewinkelte Randbereich steht mit der Wandstärke des Geräteträgers vom Tragbereich ab. Zusätzlich oder alternativ kann der Tragbereich um einen Versatz gegenüber dem angrenzenden Bereich versetzt sein, der etwa gleich groß ist wie die Wandstärke des Blechkörpers, aus dem der Geräteträger hergestellt ist. Mit anderen Worten, der Tragbereich ist gegenüber dem angrenzenden Bereich um die Wandstärke des Geräteträgers versetzt. Die Formulierung "etwa gleich groß" soll grundsätzlich Abweichungen von ± 50 % oder ± 20 % gegenüber dem Wert der Wandstärke zulassen.Expediently, the respective angled edge section can now protrude from the support region by a height which is approximately the same as the wall thickness of the sheet metal body from which the device carrier is made. In other words, the angled edge region is with the wall thickness of the device carrier from the support area. Additionally or alternatively, the support region may be offset by an offset relative to the adjacent region, which is approximately the same size as the wall thickness of the sheet metal body from which the device carrier produced is. In other words, the support area is offset from the adjacent area by the wall thickness of the device carrier. The wording "about the same size" should allow deviations of ± 50% or ± 20% compared to the value of the wall thickness.
Bei einer anderen vorteilhaften Ausführungsform kann das Leuchtmittel eine Leuchtstoffröhre sein, so dass am Geräteträger zwei einander gegenüberliegende Fassungen zum Halten der Leuchtstoffröhre vorgesehen sind. Zweckmäßig kann nun ein die Leuchtstoffröhre umhüllendes Schutzrohr vorgesehen sein, das ebenfalls an den beiden Fassungen gehalten ist.In another advantageous embodiment, the lighting means may be a fluorescent tube, so that the device carrier two opposing sockets are provided for holding the fluorescent tube. Appropriately, a protective tube surrounding the fluorescent tube can now be provided, which is likewise held on the two sockets.
Ein erfindungsgemäßer Geräteträger charakterisiert somit durch eine Öffnung für einen Fuß einer Fassung, deren Öffnungsrand an einem Tragbereich des Geräteträgers ausgebildet ist, der gegenüber einem daran angrenzenden Bereich des Geräteträgers versetzt angeordnet ist.An inventive device carrier thus characterized by an opening for a foot of a socket whose opening edge is formed on a support portion of the device carrier, which is arranged offset relative to an adjacent thereto region of the device carrier.
Üblicherweise nimmt das Tragprofil eine Verkabelung zur Stromversorgung des jeweiligen Leuchtmittels auf. Die Verkabelung kann dabei durch den Fuß zur Fassung und über die Fassung dann zum jeweiligen Leuchtmittel geführt sein.Usually, the support profile receives a wiring to the power supply of the respective bulb. The wiring can be performed by the foot to the socket and then on the socket to the respective bulb.
Zweckmäßig kann der Fuß einen rechteckigen Querschnitt aufweisen und insbesondere vier Rastelemente besitzen, die beispielsweise kreuzförmig angeordnet sein können. Komplementär zum Fuß kann die Öffnung einen rechteckigen Querschnitt aufweisen.Suitably, the foot may have a rectangular cross-section and in particular have four locking elements, which may be arranged, for example, cross-shaped. Complementary to the foot, the opening may have a rectangular cross-section.
Der an den Tragbereich angrenzende Bereich kann den Tragbereich vollständig umschließen, wodurch die Aussteifung des Tragbereichs allseitig realisierbar ist. Eine Tragbereichebene, in welcher sich der ebene Tragbereich erstreckt, ist gegenüber einer Geräteträgerebene, in welcher sich der zumindest in der Längsrichtung des Geräteträgers an den Tragbereich angrenzende ebene Bereich des Geräteträgers erstreckt, senkrecht versetzt, derart, dass die Tragbereichebene parallel und beabstandet zur Geräteträgerebene verläuft.The region adjacent to the support region can completely surround the support region, as a result of which the stiffening of the support region can be realized on all sides. A support region plane, in which the planar support region extends, is offset vertically relative to a device support plane in which the planar region of the device support adjoins the support region, at least in the longitudinal direction of the device support, such that the support region plane extends parallel to and spaced from the device support plane ,
Der Geräteträger ist zweckmäßig lösbar am Tragprofil befestigt. Vorzugsweise ist der Geräteträger mit dem Tragprofil verclipst, was die Montage vereinfacht.The equipment carrier is suitably releasably attached to the support profile. Preferably, the equipment carrier is clipped to the support profile, which simplifies installation.
