Description

Die Erfindung betrifft ein Leuchtengehäuse, insbesondere für Einbauleuchten, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a luminaire housing, in particular for recessed luminaires, according to the preamble of claim 1.

Die Erfindung ist insbesondere für ein- oder mehrlampige Einbaurasterleuchten vorgesehen, bei denen in einem Leuchtengehäuse elektrische Einbauteile, Leuchtmittel und im Bereich einer nach unten gerichteten Lichtaustrittsöffnung ein Leuchtenraster angeordnet sind.The invention is intended in particular for single or multi-lamp built-in grid lights, in which a luminaire grid is arranged in a luminaire housing electrical components, lighting means and in the region of a downwardly directed light exit opening.

Das Leuchtenraster ist in aller Regel absenkbar und einseitig abklappbar angeordnet oder kann aus dem Leuchtengehäuse entfernt werden, wenn beispielsweise ein Leuchtmittelwechsel vorgenommen werden soll.The luminaire grid is usually lowered and arranged hinged on one side or can be removed from the luminaire housing, if, for example, a bulb replacement is to be made.

Es ist bekannt, die Leuchtenraster mechanisch und elektrisch mit dem Leuchtengehäuse zu verbinden, wobei es vorteilhaft ist, eine selbsttätige elektrische Schutzleiterverbindung zwischen dem Leuchtenraster und dem Leuchtengehäuse in eine mechanische Befestigungseinrichtung zu integrieren. Hierzu sind zusätzliche Einbauteile, beispielsweise Führungselemente, erforderlich, welche am Leuchtengehäuse befestigt werden müssen und in welche Befestigungsmittel des Leuchtenrasters eingreifen und geführt werden ( DE 197 06 500 B2 , DE 195 05 471 C2 , DE 86 32 021.1 U1 ).It is known to connect the luminaire grid mechanically and electrically to the luminaire housing, wherein it is advantageous to integrate an automatic electrical protective conductor connection between the luminaire grid and the luminaire housing into a mechanical fastening device. For this purpose, additional built-in parts, such as guide elements required, which must be attached to the lamp housing and in which fasteners of the luminaire grid intervene and are guided ( DE 197 06 500 B2 . DE 195 05 471 C2 . DE 86 32 021.1 U1 ).

Es ist auch bekannt, das Leuchtengehäuse mit abgestuften oder abgeschrägten Gehäuseseitenwänden auszubilden und im Bereich der Stufen oder Schrägen Ausschnitte als Führungsöffnungen für die an dem Leuchtenraster befestigten Befestigungsmittel vorzusehen ( EP 0 271 770 B1 ).It is also known to form the lamp housing with stepped or beveled housing side walls and in the area of the steps or bevels cutouts as guide openings for the fasteners attached to the luminaire grid ( EP 0 271 770 B1 ).

Das Dokument US 3035165 offenbart dem des Anspruchs 1.The document US 3,035,165 discloses that of claim 1.

Nachteile der bekannten Leuchtengehäuse mit zusätzlichen Einbauteilen oder mit gestuften oder abgeschrägten Gehäuseseitenwänden sind eine relativ aufwendige Fertigung und Handhabung bei der Montage des Leuchtengehäuses bzw. der Leuchte und die damit verbundenen Fertigungs- und Montagekosten.Disadvantages of the known luminaire housing with additional built-in parts or with stepped or bevelled housing side walls are a relatively complex production and handling during assembly of the luminaire housing or the lamp and the associated manufacturing and assembly costs.

Der Erfindung liegt die Aufgabe zugrunde, ein Leuchtengehäuse, insbesondere für Einbaurasterleuchten zu schaffen, welches außerordentlich einfach und kostengünstig hergestellt werden kann und eine effiziente Montage des Leuchtenrasters und der Leuchte ermöglicht. Außerdem soll eine stabile und insbesondere selbsttätige Schutzleiterverbindung zwischen dem Leuchtengehäuse und Leuchtenraster mit besonders geringem Aufwand herstellbar sein.The invention has for its object to provide a lamp housing, especially for Einbaurasterleuchten, which can be made extremely simple and inexpensive and allows efficient installation of the luminaire grid and the lamp. In addition, a stable and especially automatic protective conductor connection between the luminaire housing and luminaire grid with particularly little effort to produce.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Zweckmäßige und vorteilhafte Ausgestaltungen sind in den Unteransprüchen und in der Figurenbeschreibung enthalten.According to the invention the object is achieved by the features of claim 1. Advantageous and advantageous embodiments are contained in the subclaims and in the description of the figures.

Die Erfindung geht von dem Grundgedanken aus, ein außerordentlich einfaches Leuchtengehäuse vorzusehen, welches keine zusätzlichen Einbauteile zum Eingriff und zur Führung der Befestigungsmittel des Leuchtenrasters und auch keine gestuften oder schrägen Gehäuseseitenwände mit im Bereich der Stufen oder Schrägen ausgebildeten Führungsöffnungen für die Befestigungsmittel des Leuchtenrasters erforderlich macht.The invention is based on the basic idea of providing an extremely simple luminaire housing which does not require any additional installation parts for engagement and guidance of the fastening means of the luminaire grid and also no stepped or oblique housing side walls with guide openings formed in the region of the steps or bevels for the fastening means of the luminaire grid ,

Erfindungsgemäß sind die Gehäuseseitenwände prinzipiell vertikal und parallel zueinander ausgerichtet und weisen in den Bereichen, in denen die Befestigungsmittel für das Leuchtenraster verstellbar und lösbar gehalten sind, Befestigungsflächen auf, welche im Wesentlichen horizontal in den Gehäuseinnenraum des Leuchtengehäuses ragend angeordnet und mit den Führungsöffnungen für den Eingriff und die Führung jeweils eines Befestigungselementes für das Leuchtenraster versehen sind.According to the invention, the housing side walls are in principle vertically aligned and parallel to each other and have in the areas in which the fastening means for the luminaire grid are adjustably and detachably held, fastening surfaces which are arranged horizontally projecting substantially horizontally into the housing interior of the luminaire housing and provided with the guide openings for the engagement and guidance of a fastening element for the luminaire grid.

Die wesentlichen Vorteile des erfindugnsgemäßen Leuchtengehäuses bestehen darin, dass die Führungsöffnungen und die Befestigungsflächen in dem Leuchtengehäusezuschnitt, das heißt, in dem planen, unabgekanteten Leuchtengehäuseblech, eingebracht und z.B. in einem Fertigungsschritt ausgestanzt werden können und dass die zweckmäßigerweise dreiseitigen Ausstanzungen für die Befestigungsflächen, welche zunächst nicht umgebogen bzw. abgewinkelt werden, mit den Gehäuseseitenwänden fluchten und dadurch die weitere Fertigung, beispielsweise das Abkanten, die Lagerung und Komplettierung des Leuchtengehäuses bzw. der Leuchte nicht behindern können.The main advantages of the luminaire housing according to the invention are that the guide openings and the mounting surfaces are incorporated in the luminaire housing blank, that is to say in the planar, unobtruded luminaire housing sheet, and, e.g. can be punched out in a manufacturing step and that the expediently three-sided punched for the mounting surfaces, which are initially not bent or angled, aligned with the housing side walls and thus the further manufacturing, such as folding, storage and completion of the lamp housing or the lamp not can hamper.

Das Um- oder Abbiegen der ausgestanzten Befestigungsflächen kann vorteilhaft erst im fertigen, abgekanteten Leuchtengehäuse, beispielsweise während der Montage der Einbauteile und/oder des Leuchtenrasters, erfolgen.The turning or bending of the stamped attachment surfaces can advantageously be done only in the finished, beveled luminaire housing, for example during assembly of the mounting parts and / or the luminaire grid.

Es ist vorteilhaft, dass die Befestigungsflächen mit den Führungsöffnungen für die Rasterbefestigungsmittel vor Ort und außerordentlich rasch, insbesondere mit einem einfachen Handwerkzeug, in eine nahezu horizontale, in den Gehäuseinnenraum ragende Position umgebogen werden können.It is advantageous that the attachment surfaces with the guide openings for the grid fasteners on site and extremely quickly, in particular with a simple hand tool, in a nearly horizontal, projecting into the housing interior position can be bent.

Das manuelle Umbiegen der Befestigungsflächen wird weiter erleichtert, wenn die Biegekante, die auch als Verbindungsseite der Befestigungsfläche an den Gehäusewänden betrachtet werden kann, durch Perforationen vorgegeben ist. Zweckmäßigerweise können die Perforationen, welche punkt- oder schlitzförmig und dergleichen ausgebildet werden können, zusammen mit den Ausstanzungen eingebracht werden.The manual bending of the mounting surfaces is further facilitated if the bending edge, which also considered as the connecting side of the mounting surface on the housing walls can be, is predetermined by perforations. Conveniently, the perforations, which can be formed point or slot-shaped and the like, can be introduced together with the punched-out.

Die vorteilhaften Perforationen ermöglichen außerdem eine Lagebestimmung der Biegekante.The advantageous perforations also allow a determination of the position of the bending edge.

Ein weiterer Vorteil des Leuchtengehäuses mit ausgestanzten und nachträglich umbiegbaren Befestigungsflächen mit Führungsöffnungen für die Rasterbefestigungselemente besteht darin, dass eine selbsttätige und stabile Schutzleiterverbindung im Bereich der Führungsöffnungen und der Befestigungsflächen vorgesehen werden kann.Another advantage of the lamp housing with stamped and subsequently bendable mounting surfaces with guide openings for the grid fasteners is that an automatic and stable protective conductor connection in the region of the guide openings and the mounting surfaces can be provided.

Vorteilhaft ist ein Kontaktelement vorgesehen, welches von der Führungsöffnung her auf einen Bereich der Befestigungsfläche aufgeschoben und in seiner Wirklage zusätzlich gesichert werden kann.Advantageously, a contact element is provided, which can be pushed from the guide opening onto a region of the fastening surface and additionally secured in its operative position.

Wenn in einer bevorzugten Ausbildung die Befestigungsflächen und die darin vorgesehene Führungsöffnungen sowie die Ausbrüche in den Gehäuseseitenwänden, welche nach dem Umbiegen der Befestigungsflächen entstehen, eine rechteckige Kontur mit Längsseiten und wesentlich kürzeren Stirnseiten aufweisen, kann das Kontaktelement vorteilhaft auf einen stirnseitigen Bereich der Befestigungsfläche aufgeschoben werden, um mit einem als Federbügel ausgebildeten Befestigungselement zusammenzuwirken.If in a preferred embodiment, the attachment surfaces and the guide openings provided therein and the breakouts in the housing side walls, which arise after bending the mounting surfaces have a rectangular contour with long sides and much shorter end faces, the contact element can be advantageously pushed onto a frontal region of the mounting surface to cooperate with a fastener designed as a spring clip.

Vorteilhaft ist das Kontaktelement annähernd U-förmig ausgebildet und mit vor- bzw. überstehenden Kontaktecken versehen, welche bei der Montage die Lackierung des Leuchtengehäuses im Bereich der Befestigungsflächen ankratzen und eine ausreichende, dauerhaft gegen Korrosion geschützte elektrische Verbindung zwischen dem Leuchtengehäuse und dem metallischen Leuchtenraster herstellen.Advantageously, the contact element is approximately U-shaped and provided with protruding or protruding contact corners, which scratch the painting of the lamp housing in the region of the mounting surfaces during assembly and produce a sufficient, permanently protected against corrosion electrical connection between the luminaire housing and the metallic luminaire grid.

Zu diesem Zweck ist das Kontaktelement aus einem nichtrostenden, federnden Metall bzw. einer Metalllegierung hergestellt, und das Befestigungselement des Leuchtenrasters, beispielsweise ein Federbügel, liegt mit Spreizschenkeln ständig an den Stirnseiten der Führungsöffnungen und damit an dem hier befestigten Kontaktelement an. Das Rasterbefestigungsmittel ist vorteilhafterweise ebenfalls aus einem federnden, nicht rostenden Metall bzw. einer Metalllegierung hergestellt und in der Regel lösbar am Leuchtenraster, beispielsweise mit Hilfe eines Halteelementes, befestigt.For this purpose, the contact element is made of a stainless, resilient metal or a metal alloy, and the fastening element of the light grid, such as a spring clip, is located with expansion limbs constantly on the end faces of the guide openings and thus on the attached contact element here. The grid fastener is advantageously also made of a resilient, non-rusting metal or a metal alloy and usually releasably attached to the luminaire grid, for example by means of a holding element attached.

Besonders vorteilhaft ist ein Sicherungselement, welches als ein um etwa 90° umgebogener Klemmsteg an einem Basisteil des Kontaktelementes angeformt ist und das aufgeschobene Kontaktelement in einer Klemmhalterung sichert. Diese Sicherung erfolgt auch, wenn die Spreizschenkel des Befestigungselementes nicht federnd in der Führungsöffnung und damit an dem U-förmigen Kontaktschenkel des Kontaktelementes anliegen und somit auch bei abgehängtem Leuchtenraster und aus der Führungsöffnung entnommenen Befestigungselement. Zur Ausbildung und Befestigung eines U-förmigen Federbügels wird auf die DE 197 06 500 B2 verwiesen.Particularly advantageous is a securing element, which is formed as a bent by about 90 ° clamping bar on a base part of the contact element and secures the deferred contact element in a clamp. This backup is also carried out when the expansion legs of the fastener not resiliently rest in the guide opening and thus on the U-shaped contact leg of the contact element and thus also with suspended luminaire grid and removed from the guide opening fastener. For training and attachment of a U-shaped spring clip is on the DE 197 06 500 B2 directed.

In Figur 1 ist als Leuchte 2 eine einlampige Einbaurasterleuchte mit einem Leuchtengehäuse 3, einem Leuchtenraster 6 und Befestigungselementen 16 gezeigt.In FIG. 1 is shown as a lamp 2 einlampige Einbaurasterleuchte with a lamp housing 3, a light grid 6 and fasteners 16.

Das Leuchtenraster 6 ist als Parabolspiegelraster ausgebildet und weist zwei Längsseiten 25, 26 und Querlamellen 27 auf. Das Leuchtenraster 6 wird von einander gegenüberliegenden Befestigungselementen 16 am Leuchtengehäuse 3 gehalten und kann aus der in den Figuren 1 und 2 gezeigten Position, in welcher das Leuchtenraster 6 im Bereich einer Lichtaustrittsöffnung 13 des Leuchtengehäuses 3 angeordnet ist, nach unten verstellt, einseitig ausgehängt und auch vom Leuchtengehäuse 3 gelöst werden (siehe Fig. 5).The luminaire grid 6 is formed as a parabolic louvre and has two longitudinal sides 25, 26 and transverse blades 27. The luminaire grid 6 is held by opposing fastening elements 16 on the lamp housing 3 and can from the in the Figures 1 and 2 shown position in which the lighting grid 6 is arranged in the region of a light exit opening 13 of the lamp housing 3, adjusted downwards, unilaterally unhooked and also detached from the lamp housing 3 (see Fig. 5 ).

Zu diesem Zweck ist jedes Befestigungselement 16 in einer Führungsöffnung 5, welche in den nahezu vertikal ausgerichteten Gehäuseseitenwänden 4 ausgebildet ist, geführt. Die Herstellung der Führungsöffnungen 5 im Bereich von Befestigungsflächen 7 geht aus den Figuren 2, 3 und 4 hervor.For this purpose, each fastening element 16 in a guide opening 5, which is formed in the nearly vertically oriented housing side walls 4, out. The preparation of the guide openings 5 in the region of attachment surfaces 7 goes out of the Figures 2 . 3 and 4 out.

Figur 3 vermittelt die Ausschnitte bzw. Ausstanzungen, welche bereits im planen Leuchtengehäuseblech bzw. im Leuchtengehäusezuschnitt (nicht dargestellt) eingebracht wurden. Dabei wird jede Führungsöffnung 5 in Form eines Schlitzes bzw. eines Rechtecks mit parallelen Längsseiten und parallelen, relativ kurzen Stirnseiten ausgebildet. FIG. 3 conveys the cutouts or punched holes, which have already been introduced in the flat luminaire housing sheet or in the luminaire housing blank (not shown). In this case, each guide opening 5 is formed in the form of a slot or a rectangle with parallel longitudinal sides and parallel, relatively short end faces.

Bei den Ausstanzungen für die Befestigungsflächen 7 handelt es sich um dreiseitige Materialausstanzungen 15 sowie um Perforationen 30, welche eine Biegekante bzw. eine Verbindungsseite 20 markieren und das Umbiegen, insbesondere das manuelle Umbiegen, sowie die Lagebestimmung der Biegekante optimieren. Nach dem Umbiegen der Befestigungsfläche 7 um die Verbindungsseite 20 sind eine in den Gehäuseinnenraum 8 des Leuchtengehäuses 3 ragende Befestigungsfläche 7 mit Führungsöffnung 5 und in den Gehäuseseitenwänden 4 jeweils ein Ausbruch 9 gebildet.The punch-outs for the attachment surfaces 7 are three-sided material punching 15 and perforations 30, which mark a bending edge or a connecting side 20 and optimize the bending, in particular the manual bending, as well as the orientation of the bending edge. After bending over the attachment surface 7 about the connection side 20, a fastening surface 7 protruding into the housing interior 8 of the luminaire housing 3 with a guide opening 5 and an opening 9 in the housing side walls 4 are formed.

In Fig. 2 ist die Befestigungsfläche 7 mit Führungsöffnung 5 vor dem Umbiegen in den Gehäuseinnenraum 8 strichliert und nach dem Umbiegen mit durchgezogenen Linien gezeigt.In Fig. 2 is the mounting surface 7 with guide opening 5 before bending into the housing interior 8 dashed and shown after bending with solid lines.

Figur 4 verdeutlicht, dass jede nach innen ragende Befestigungsfläche 7 im Bereich der Führungsöffnung 5 zur Aufnahme eines Befestigungselementes 16 (siehe Fig. 1 und 2) und zur Führung des Befestigungselementes 16 geeignet ist. Durch das Umbiegen in Richtung Gehäuseinnenraum 8 wird jeweils ein Ausbruch 9 in der Gehäuseseitenwand 4 gebildet. FIG. 4 illustrates that each inwardly projecting mounting surface 7 in the region of the guide opening 5 for receiving a fastener 16 (see Fig. 1 and 2 ) and is suitable for guiding the fastening element 16. By bending in the direction of the housing interior 8 in each case an outbreak 9 is formed in the housing side wall 4.

Aus Figur 4 geht auch hervor, dass die im planen, unabgekanteten Gehäuseblech eingebrachten Ausstanzungen für die Führungsöffnungen 5 und Befestigungsflächen 7 den weiteren Herstellungsprozess des Leuchtengehäuses 3 nicht behindern. Die nach innen ragenden Befestigungsflächen 7 können erst während der Montage der Einbauteile bzw. für die Befestigung des Leuchtenraster durch einfaches Umbiegen, beispielsweise mit einem Handwerkzeug, ausgebildet werden.Out FIG. 4 also shows that the introduced in the plan, unabgekanteten housing plate punched holes for the guide openings 5 and mounting surfaces 7 do not hinder the further manufacturing process of the lamp housing 3. The inwardly projecting mounting surfaces 7 can be formed only during assembly of the mounting parts or for the attachment of the luminaire grid by simply bending, for example with a hand tool.

Figur 5 zeigt im oberen Bereich das Leuchtengehäuse 3 mit nach innen ragenden Befestigungsflächen 7, darin ausgebildeten Führungsöffnungen 5 und einem aufgeschobenem Kontaktelement 10 für eine Schutzleiterverbindung. Zwei Pfeile zeigen an, dass das am Leuchtenraster 6 gehaltene Befestigungselement 16, welches ein U-förmiger Federbügel mit zwei Spreizschenkeln 24 ist, im zusammengedrückten Zustand durch die Führungsöffnung 5 in der linken Gehäuseseitenwand 4 eingeführt werden kann. Danach liegen die Spreizschenkel 24 im Bereich der Stirnseiten der Führungsöffnung 5 an, so dass eine elektrische Verbindung über das hier angeordnete Kontaktelement 20 zwischen dem Leuchtenraster 6 und dem Leuchtengehäuse 3 gewährleistet ist (siehe Fig. 2). FIG. 5 shows in the upper part of the lamp housing 3 with inwardly projecting mounting surfaces 7, formed therein guide openings 5 and a deferred contact element 10 for a protective conductor connection. Two arrows indicate that the held on the light grid 6 fastener 16, which is a U-shaped spring clip with two expansion legs 24 can be inserted in the compressed state through the guide opening 5 in the left side wall 4 of the housing. Thereafter, the expansion legs 24 are in the region of the end faces of the guide opening 5, so that an electrical connection via the contact element 20 arranged here between the light grid 6 and the lamp housing 3 is ensured (see Fig. 2 ).

Gleiche Merkmale in den Figuren sind mit identischen Bezugszeichen versehen.Identical features in the figures are provided with identical reference numerals.

Ausbildung und Anordnung des Kontaktelementes 10 sind weiter in den Figuren 6 bis 8 gezeigt. Das Kontaktelement 10 weist ein Basisteil 21 mit überstehenden Kontaktecken oder -spitzen 11 auf. Mit diesen Kontaktecken 11 wird der Lack des Leuchtengehäuses 3 im Bereich der Befestigungsflächen 7 (Fig. 6) abgekratzt. Der Kontakt zwischen dem Befestigungselement 16 (siehe Fig. 2) und dem Kontaktelement 10 erfolgt im Bereich eines U-förmigen Kontaktschenkels 22, welcher an dem Basisteil 21 angeformt ist. Die U-förmige Öffnung und die Gesamtlänge des Kontaktelementes 10 sind auf die Blechdicke des Leuchtengehäuses 3 bzw. auf die Länge eines stirnseitigen Bereiches 12 der Befestigungsfläche 7 abgestimmt und ein Sicherungselement 23 kann die Befestigungsfläche 7 stirnseitig umgreifen.Training and arrangement of the contact element 10 are further in the FIGS. 6 to 8 shown. The contact element 10 has a base part 21 with protruding contact corners or tips 11. With these contact corners 11 of the paint of the lamp housing 3 in the region of the mounting surfaces 7 (FIG. Fig. 6 ) scraped off. The contact between the fastener 16 (see Fig. 2 ) and the contact element 10 takes place in the region of a U-shaped contact leg 22, which is integrally formed on the base part 21. The U-shaped opening and the total length of the contact element 10 are matched to the sheet thickness of the lamp housing 3 and to the length of an end region 12 of the mounting surface 7 and a securing element 23, the mounting surface 7 engage around the front side.

Auf diese Weise wird eine Rast- und Klemmhalterung des Kontaktelementes 10 erreicht.In this way, a latching and clamping holder of the contact element 10 is achieved.

Vorteilhaft ist das Kontaktelement 10 von der Führungsöffnung 5 aus auf den stirnseitigen Bereich 12 aufschiebbar und das Sicherungselement 23, welches eine 90° -Umbiegung am Basisteil 21 darstellt, kann in der Wirklage verrasten. Eine stabile und sichere Schutzleiterverbindung mit Hilfe des Kontaktelementes 10 ist damit jederzeit und unabhängig von der Anlage der Spreizschenkel 24 des Befestigungselementes 16 gewährleistet.Advantageously, the contact element 10 can be pushed onto the frontal region 12 from the guide opening 5, and the securing element 23, which represents a 90 ° bend on the base part 21, can engage in the effective position. A stable and safe protective conductor connection with the aid of the contact element 10 is thus ensured at any time and independently of the system of the expansion leg 24 of the fastening element 16.
