Description

Die Erfindung betrifft eine Vorrichtung zur Beleuchtung von Fahrzeugen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for illuminating vehicles according to the preamble of patent claim 1.

Aus der DE 44 18 399 A1 ist eine Vorrichtung zur Beleuchtung von Fahrzeugen bekannt, die einen Lichtquellenträger mit einer Aufnahme für eine Lichtquelle aufweist, wobei der Lichtquellenträger elektrische Kontaktelemente aufweist zur elektrischen Verbindung mit der Lichtquelle einerseits und zur elektrischen Verbindung mit an einer Rückwand eines Gehäuses angeordneten elektrischen Anschlüssen andererseits, von denen elektrische Leitungen zu einer ortsfern angeordneten elektrischen Spannungsquelle abführen. Die elektrischen Leitungen verlaufen innerhalb des Gehäuses von einer elektrischen Anschlusstelle im Bereich einer Öffnung der Rückwand, in die der Lichtquellenträger einsetzbar ist, zu einem in einer weiteren Öffnung der Rückwand angeordneten zentralen Steckerteil, von dem aus die von den einzelnen Lichtquellen ankommenden Leitungen zusammengefasst zu der ortsfern angeordneten elektrischen Spannungsquelle weitergeleitet werden.From the DE 44 18 399 A1 a device for illuminating vehicles is known which has a light source carrier with a receptacle for a light source, wherein the light source carrier has electrical contact elements for electrical connection to the light source on the one hand and for electrical connection with arranged on a rear wall of a housing electrical connections on the other hand, of which dissipate electrical leads to a remote electrical voltage source. The electrical lines run within the housing from an electrical connection point in the region of an opening of the rear wall into which the light source carrier can be inserted to a arranged in a further opening of the rear wall central connector part, from which the incoming of the individual light sources lines to the remote electrical voltage source can be forwarded.

Zum Anbringen der Lichtquelle an der Rückwand des Gehäuses ist es erforderlich, dass die elektrischen Leitungen von einer Innenseite des Gehäuses her im Bereich der Öffnung an Kontaktierungsstellen angebracht sind. Erst in einem weiteren Schritt kann die in den Lichtquellenträger eingesetzte und kontaktierte Lichtquelle zusammen mit dem Lichtquellenträger von hinten in die Öffnung der Rückwand des Gehäuses eingesetzt und dann durch Verdrehen des Lichtquellenträgers um seine Längsachse in eine Verriegelungsstellung mit gleichzeitiger Kontaktierung der Anschlusselemente des Lichtquellenträgers mit Anschlussenden der elektrischen Leitung verbracht werden.For attaching the light source to the rear wall of the housing, it is necessary that the electrical lines are mounted from an inner side of the housing in the region of the opening at contacting points. Only in a further step, the light source used in the light source carrier and contacted light source can be used together with the light source carrier from behind into the opening of the rear wall of the housing and then by rotating the light source carrier about its longitudinal axis in a locking position with simultaneous contacting of the connection elements of the light source carrier with terminal ends of the be spent electrical line.

Nachteilig an der bekannten Vorrichtung ist, dass der Aufwand für das Anbringen von elektrischen Kontaktelementen an der Rückwand des Gehäuses relativ aufwendig ist. Neben dem Vorsehen eines zentralen Steckerteils in einer Öffnung der Rückwand sind an einer Kontaktierungsstelle im Bereich des angesetzten Lichtquellenträgers Kontaktierungsmaßnahmen notwendig. Der Montageaufwand ist hierdurch relativ groß.A disadvantage of the known device that the cost of attaching electrical contact elements on the rear wall of the housing is relatively expensive. In addition to the provision of a central plug part in an opening of the rear wall contacting measures are necessary at a contact point in the region of the attached light source carrier. The assembly effort is thereby relatively large.

Aus der DE 198 22 895 A1 ist eine Vorrichtung zur Beleuchtung von Fahrzeugen mit einer Lichtquelle und einem Lichtquellenträger bekannt. Der Lichtquellenträger ist über ein Adapter mit der Rückwand eines Gehäuses lösbar verbunden. Der Adapter verfügt über Befestigungsmittel zur mechanischen Verbindung mit dem Lichtquellenträger. Der Adapter verfügt über Kontaktelemente, so dass eine elektrische Verbindung hergestellt werden kann zum einen mit Kontaktelementen des Lichtquellenträgers und zum anderen mit Anschlussenden der elektrischen Leitung, die in Verbindung steht mit einer elektrischen Spannungsquelle. Diese Vorrichtung offenbart keine Aufnahmenut, in der ein Kontaktelement zur elektrischen Verbindung mit Kontaktelementen des Lichtquellenträgers angeordnet sein kann.From the DE 198 22 895 A1 a device for illuminating vehicles with a light source and a light source carrier is known. The light source carrier is detachably connected via an adapter to the rear wall of a housing. The adapter has fasteners for mechanical connection to the light source carrier. The adapter has contact elements, so that an electrical connection can be made on the one hand with contact elements of the light source carrier and on the other with connection ends of the electrical line, which is in communication with an electrical voltage source. This device does not disclose a receiving groove in which a contact element for electrical connection with contact elements of the light source carrier can be arranged.

Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zur Beleuchtung von Fahrzeugen anzugeben, so dass zum einen eine einfache und sichere Kontaktverbindung der Lichtquelle im Bereich der Gehäuserückwand erzielt wird und dass zum anderen der Montageaufwand verringert wird.Object of the present invention is therefore to provide a device for illuminating vehicles, so that on the one hand a simple and secure contact connection of the light source is achieved in the region of the rear wall and that on the other hand, the assembly cost is reduced.

Zur Lösung dieser Aufgabe weist die Erfindung die Merkmale des Patentanspruchs 1 auf.To solve this problem, the invention has the features of claim 1.

Nach der Erfindung ist ein Adapter vorgesehen, so dass zum einen eine mechanische Verbindung an einer Rückwand des Gehäuses geschaffen wird. Zum anderen ist der Adapter derart ausgebildet, dass eine elektrische Verbindung zwischen der Lichtquelle bzw. dem Lichtquellenträger und den zu der ortsfern angeordneten Spannungsquelle hinführenden elektrischen Leitungen unter Umgehung von Kontaktierungsmaßnahmen an der Rückwand des Gehäuses erfolgen kann. Bei der elektrischen Kontaktierung erfolgt somit eine Entkopplung der Rückwand des Gehäuses, so dass die Montage der Lichtquelle an der Rückwand des Gehäuses vereinfacht wird. Der Adapter stellt ein mechanisches Verbindungselement zwischen dem Lichtquellenträger und dem Gehäuse dar. Dadurch, dass der Adapter bereits Kontaktelemente zur elektrischen Verbindung mit Anschlussenden der elektrischen Leitungen aufweist, können diese Anschlussenden bereits vor Montage des Lichtquellenträgers elektrisch mit den Kontaktelementen des Adapters verbunden sein, wobei der Adapter als Zwischenprodukt zur Montage bereitgestellt werden kann. Zusammen mit dem Lichtquellenträger wird der Adapter in die Öffnung der Rückwand eingesetzt und mit derselben mechanisch verbunden. Erfindungsgemäß ist der Adapter ringförmig ausgebildet und weist mindestens zwei Rastnasen mit Widerhaken auf, die nach dem Einsetzen des Adapters in die Öffnung die Rückwand des Gehäuses hintergreifen. Auf diese Weise wird eine sichere formschlüssige Verbindung zwischen dem Adapter und der Rückwand gewährleistet, die nur in Ausnahmefällen durch Verbiegen der Rastnasen in Querrichtung zur Längsachse des Lichtquellenträgers gelöst werden kann. Vorteilhaft erfolgt die Montage des Adapters ausschließlich durch eine Längsbewegung desselben zusammen mit dem Lichtquellenträger, bis die vorzugsweise gegenüberliegend angeordneten Rastnasen mit ihren Widerhaken die Gehäuserückwand hintergreifen. Erfindungsgemäß weist der Adapter an einer der Gehäuserückwand abgewandten hinteren Seite eine Nut zur Aufnahme von Anschlussenden der elektrischen Leitungen (Anschlussenden Aufnahmenut) auf, in der die Anschlussenden der elektrischen Leitung mit den Kontaktelementen des Adapters elektrisch verbunden sind. Die Kontaktierung der Anschlussenden der elektrischen Leitung erfolgt somit in einem definierten und vorzugsweise durch einen Axialkragen nach außen hin abgedeckten Bereich des Adapters. Eine Zugänglichkeit der elektrischen Kontaktelemente von außen wird vermieden, so dass sich bei Wechsel der Lichtquelle kein unerwünschter Kurzschluss mit negativen Wirkungen auf die Bordelektronik einstellen kann.According to the invention, an adapter is provided so that on the one hand a mechanical connection is provided on a rear wall of the housing. On the other hand, the adapter is designed such that an electrical connection between the light source or the light source carrier and the electrical power lines leading to the remote location of the voltage source can be made bypassing contacting measures on the rear wall of the housing. In the electrical contacting thus takes place decoupling of the rear wall of the housing, so that the mounting of the light source is simplified to the rear wall of the housing. The adapter represents a mechanical connecting element between the light source carrier and the housing. Due to the fact that the adapter already has contact elements for the electrical connection to terminal ends of the electrical lines, these connecting ends can be electrically connected to the contact elements of the adapter before the light source carrier has been mounted Adapter can be provided as an intermediate for assembly. Together with the light source carrier, the adapter is inserted into the opening of the rear wall and mechanically connected to the same. According to the invention the adapter is annular and has at least two locking lugs with barbs, which engage behind the rear wall of the housing after insertion of the adapter into the opening. In this way, a secure positive connection between the adapter and the rear wall is ensured, which can only be solved in exceptional cases by bending the locking lugs in the transverse direction to the longitudinal axis of the light source carrier. Advantageously, the assembly of the adapter takes place solely by a longitudinal movement of the same together with the light source carrier until the preferably oppositely arranged locking lugs engage behind the rear wall of the housing with their barbs. According to the invention, the adapter has, on a rear side remote from the rear wall of the housing, a groove for receiving connection ends of the electrical lines (connection ends receiving groove), in which the connection ends of the electrical line are electrically connected to the contact elements of the adapter. The contacting of the terminal ends of the electrical line thus takes place in a defined and preferably by an axial collar to the outside covered area of the adapter. An accessibility the electrical contact elements from the outside is avoided, so that when changing the light source no unwanted short circuit can set negative effects on the on-board electronics.

Nach einer Weiterbildung der Erfindung weist der Adapter Befestigungsmittel auf, mittels derer der Adapter lösbar mit dem Lichtquellenträger einerseits und der Rückwand des Gehäuses andererseits verbunden ist. Vorteilhaft kann hierdurch die Lichtquelle lediglich durch Entfernen des Lichtquellenträgers entnommen werden, ohne dass die elektrischen Leitungen in ihrer Position verändert werden müssten. Der Adapter kann grundsätzlich fest in der Öffnung der Rückwand verharren und dient somit als elektrisches und mechanisches Verbindungselement für den Lichtquellenträger.According to a development of the invention, the adapter has fastening means, by means of which the adapter is releasably connected to the light source carrier on the one hand and the rear wall of the housing on the other hand. Advantageously, as a result, the light source can be removed only by removing the light source carrier, without the electrical lines would have to be changed in position. The adapter can basically remain firmly in the opening of the rear wall and thus serves as an electrical and mechanical connection element for the light source carrier.

Nach einer Weiterbildung der Erfindung sind die Befestigungsmittel des Adapters bzw. des Lichtquellenträgers derart ausgebildet, dass die Haltekraft zwischen dem Adapter und der Rückwand größer ist als die Haltekraft zwischen dem Adapter und dem Lichtquellenträger. Auf diese Weise wird bei einem Wechsel der Lichtquelle gewährleistet, dass nur der Lichtquellenträger aus der montierten Position entfernt wird. Der Adapter bleibt zusammen mit den elektrischen Leitungen am Gehäuse befestigt.According to a development of the invention, the fastening means of the adapter or the light source carrier are designed such that the holding force between the adapter and the rear wall is greater than the holding force between the adapter and the light source carrier. In this way, when changing the light source ensures that only the light source carrier is removed from the mounted position. The adapter remains attached to the housing along with the electrical leads.

Nach einer Weiterbildung der Erfindung ist der Lichtquellenträger hohlzylinderförmig ausgebildet und weist Führungselemente auf, mittels derer der Lichtquellenträger passgenau in das Adapter einsetzbar ist. Zusätzlich weist der Lichtquellenträger federnde Rastnasen auf, die eine Ringwandung des Adapters hintergreifen und somit eine mechanische Verbindung mit dem Adapter herstellen.According to a development of the invention, the light source carrier is hollow-cylindrical and has guide elements, by means of which the light source carrier can be inserted accurately into the adapter. In addition, the light source carrier has resilient latching noses, which engage behind an annular wall of the adapter and thus produce a mechanical connection with the adapter.

Dadurch, dass die Rastnasen eine sich entgegen der Montagerichtung verjüngende Schrägfläche aufweisen, kann bei Angriff einer Kraft entgegen der Montagerichtung diese Angriffskraft umgelenkt werden unter Bildung einer Querkomponente, die das lösende Verbiegen der Rastnasen bewirkt. Somit kann auf einfache Weise lediglich durch Angriff einer lösenden Kraft in Längsrichtung die Verbindung zwischen dem Lichtquellenträger und dem Adapter gelöst werden. Durch Ergreifen eines Griffelementes des Lichtquellenträgers und Ausüben einer entsprechenden Kraft kann bedienungsfreundlich der Lichtquellenträger für einen Wechsel der Lichtquelle entfernt werden.Due to the fact that the latching lugs have an inclined surface which tapers counter to the mounting direction, a force can be applied against the mounting direction when a force is applied deflecting this attack force to form a transverse component, which causes the releasing bending of the locking lugs. Thus, the connection between the light source carrier and the adapter can be solved in a simple manner only by attacking a releasing force in the longitudinal direction. By grasping a grip element of the light source carrier and exerting a corresponding force, the light source carrier can be removed in a user-friendly manner for changing the light source.

Wie insbesondere aus Figur 1 und Figur 9 ersichtlich ist, weist zu diesem Zweck der Adapter 8 auf gegenüberliegenden Seiten jeweils eine Rastnase 10 auf, die mit an freien Enden angeordneten Widerhaken 11 die Rückwand 9 des Gehäuses 1 hintergreifen. Die Rastnasen 10 sind relativ verwindungssteif ausgebildet und weisen eine in Querrichtung verlaufende Vertiefung 12 auf, deren Breite zur Dicke der Rückwand 9 des Gehäuses 1 korrespondiert. Auf diese Weise ist eine sichere mechanische Verbindung zwischen dem Adapter 8 und der Rückwand 9 gewährleistet, wobei ein Entriegeln der Verbindung nur durch unmittelbaren Angriff einer Kraft an dem Ende der Rastnase 10 in Querrichtung erfolgen kann.In the present embodiment, both the light source carrier 7 and the adapter 8 fastening means, such that on the one hand the light source carrier 7 with the adapter 8 and on the other hand the adapter 8 with the rear wall 9 of the housing 1 is detachably connected. As can be seen in particular from Figure 1 and Figure 9, for this purpose, the adapter 8 on opposite sides in each case a locking lug 10 which engage behind the rear wall 9 of the housing 1 with arranged at free ends barbs 11. The locking lugs 10 are formed relatively rigid and have a transverse groove 12 in the transverse direction, whose width corresponds to the thickness of the rear wall 9 of the housing 1. In this way, a secure mechanical connection between the adapter 8 and the rear wall 9 is ensured, wherein unlocking of the connection can be made only by direct attack of a force at the end of the locking lug 10 in the transverse direction.

Der Adapter 8 dient nicht nur als mechanisches Verbindungselement zwischen dem Lichtquellenträger 7 und der Rückwand 9 des Gehäuses 1. Der Adapter 8 dient auch als Kontaktierungsring zur elektrischen Verbindung der Lichtquelle 2 an eine ortsfern angeordnete Spannungsquelle. Zu diesem Zweck weist der Adapter 8 an gegenüberliegenden Seiten eine Anschlussendenaufnahmenut 13 zur Aufnahme von Anschlussenden einer zu der Spannungsquelle hinführenden elektrischen Leitung 14 auf. Die Aufnahmenut 13 ist entlang eines Ringausschnittes des Adapters 8 auf einer der Lichtquelle 2 abgewandten Seite des Adapters 8 angeordnet, so dass die Anschlussenden sowie die elektrischen Leitungen 14 außerhalb des topfförmigen Gehäuses 1 verlaufen. Das Gehäuse 1 ist daher vorteilhaft frei von elektrischen Kontaktierungsmitteln.The adapter 8 serves not only as a mechanical connecting element between the light source carrier 7 and the rear wall 9 of the housing 1. The adapter 8 also serves as Kontaktierungsring for electrical connection of the light source 2 to a locally remote voltage source. For this purpose, the adapter 8 on opposite sides of a Anschlußenden receiving groove 13 for receiving terminal ends of an electrical line 14 leading to the voltage source. The receiving groove 13 is arranged along a ring cutout of the adapter 8 on a side facing away from the light source 2 of the adapter 8, so that the terminal ends and the electrical leads 14 extend outside of the cup-shaped housing 1. The housing 1 is therefore advantageously free of electrical contacting means.

Die Anschlussenden der elektrischen Leitung 14 sind durch Verkrimpen in der Aufnahmenut 13 mit elektrischen Kontaktelementen 15 des Adapters 8 verbunden. Damit die elektrische Kontaktierung zwischen den Anschlussenden der elektrischen Leitung 14 und den Kontaktelementen 15 nach außen hin geschützt ist, weist die Aufnahmenut 13 einen Axialkragen 16 auf, der die Kontaktierungsstelle abdeckt und schützt. Die jeweils den Anschlussenden der elektrischen Leitung 14 zugeordneten Kontaktelemente 15 des Adapters 8 sind aus einem elektrisch leitenden und verbiegbarem Material hergestellt und erstrekken sich von der Kontaktierungsstelle in der Aufnahmenut 13 von einer Außenseite 17 des Adapters 8 unter Umlenkung in Richtung einer Montagerichtung 18 um 180° auf eine Innenseite 19 des Adapters 8, an der eine weitere Kontaktierungsstelle angeordnet ist. Die Kontaktelemente 15 sind jeweils klemmend an dem Adapter 8 befestigt.The terminal ends of the electrical line 14 are connected by crimping in the receiving groove 13 with electrical contact elements 15 of the adapter 8. Thus, the electrical contact between the terminal ends of the electrical line 14 and the contact elements 15 is protected to the outside, the receiving groove 13 on an axial collar 16 which covers the contact point and protects. Each of the terminal ends of the electrical line 14 associated contact elements 15 of the adapter 8 are made of an electrically conductive and bendable material and extend from the contact point in the receiving groove 13 from an outer side 17 of the adapter 8 under deflection in the direction of mounting direction 18 by 180 ° on an inner side 19 of the adapter 8, on which a further contacting point is arranged. The contact elements 15 are each clamped to the adapter 8.

Zur elektrischen Kontaktierung des Lichtquellenträgers 7 mit den jeweiligen an der Innenseite 19 des Adapters 8 angeordneten Kontaktelementen 15 weist der Lichtquellenträger 7 in Querrichtung wirkende Kontaktfedern 20 auf, die gegenüberliegend unter Bildung einer bauchigen bzw. konvexen Form den Außenrand des Lichtquellenträgers 7 im Bereich der Kontaktierungsstellen bilden. Die Federkraft der Kontaktfedern 20 ist derart ausgebildet, dass bei mechanischer Verbindung zwischen dem Lichtquellenträger 7 und dem Adapter 8 eine vorgegebenen Kontaktierungskraft ausgeübt wird. Die Kontaktfedern 20 sind jeweils über nach innen umgelegte Kontaktleisten 21 zu einer innen liegenden Kontaktierungsstelle 22 geführt, in der nach Einsetzen der Lichtquelle 2 in eine Aufnahme 23 des Lichtquellenträgers 7 eine elektrische Verbindung zu Anschlüssen der Lichtquelle 2 hergestellt ist.For electrical contacting of the light source carrier 7 with the respective contact elements 15 arranged on the inside 19 of the adapter 8, the light source carrier 7 has transversely acting contact springs 20 which lie opposite one another forming the outer edge of the light source carrier 7 in the region of the contacting points to form a bulbous or convex shape. The spring force of the contact springs 20 is designed such that when mechanical connection between the light source carrier 7 and the adapter 8, a predetermined contacting force is exerted. The contact springs 20 are each guided over inwardly folded contact strips 21 to an inner contacting point 22, in which after insertion of the light source 2 in a receptacle 23 of the light source carrier 7, an electrical connection to terminals of the light source 2 is made.

Zur mechanisch lösbaren Verbindung des Lichtquellenträgers 7 mit dem Adapter 8 weist der Lichtquellenträger 7 an gegenüberliegenden Seiten in Querrichtung zu demselben verbiegbare Rastnasen 24 auf, die im montierten Zustand die Innenseite 19 des Adapters 8 hintergreifen. Die vorzugsweise an gegenüberliegenden Seiten paarweise angeordneten Rastnasen 24 weisen nicht nur eine Einführschrägfläche 25 auf, die in Montagerichtung 18 verjüngend ausgebildet ist zum erleichternden Einführen des Lichtquellenträgers 7 durch den Adapter 8. Darüber hinaus ist eine entgegen der Montagerichtung 18 sich verjüngende Schrägfläche 26 vorgesehen, die ein Lösen des Lichtquellenträgers 7 aus der reibschlüssigen Verbindung mit dem Adapter 8 ermöglicht. Dadurch, dass die Schrägfläche 26 einen spitzen Winkel zu der Längsachse des Lichtquellenträgers 7 bildet, liegt bei Angriff einer Entriegelungskraft entgegen der Montagerichtung 18 stets eine Querkraftkomponente vor, die radial nach innen gerichtet ist und ein Verschwenken der Rastnasen 24 nach innen bewirkt. Auf diese Weise kann der Lichtquellenträger 7 von dem Adapter 8 entriegelt und herausgeschoben werden.For mechanically detachable connection of the light source carrier 7 with the adapter 8, the light source carrier 7 on opposite sides in the transverse direction to the same bendable locking lugs 24 which engage behind the inside 19 of the adapter 8 in the mounted state. The preferably on opposite sides arranged in pairs locking lugs 24 not only have a Einführschrägfläche 25 which is tapered in the mounting direction 18 for facilitating insertion of the light source carrier 7 through the adapter 8. In addition, a counter to the mounting direction 18 is tapered inclined surface 26 is provided a release of the light source carrier 7 from the frictional connection with the adapter 8 allows. Characterized in that the inclined surface 26 forms an acute angle to the longitudinal axis of the light source carrier 7, when attacking an unlocking against the mounting direction 18 is always a transverse force component, which is directed radially inward and causes pivoting of the locking lugs 24 inward. In this way, the light source carrier 7 can be unlocked and pushed out of the adapter 8.

Der Lichtquellenträger 7 weist Führungselemente 27 auf, so dass er mit Ausnahme der Rastnasen 24 passgenau durch den ringförmigen Adapter 8 mit der Aufnahme 23 hindurchgesteckt werden kann, bis ein Flansch 28 des Lichtquellenträgers 7 an eine Ringfläche 29 des Adapters 8 anschlägt. Mit Anschlag des Flansches 28 an die Ringfläche 29 des Adapters 8 erfolgt die Einrastung der Rastnasen 24, so dass eine sichere mechanische Verbindung zwischen dem Lichtquellenträger 7 und dem Adapter 8 besteht. Vorzugsweise erfolgt vor Einführung des Lichtquellenträgers 7 in das Adapters 8 bereits das Einsetzen der Lichtquelle 2 in die Aufnahme 23 des Lichtquellenträgers 7. Zur Montage der Lichtquelle 2 an der Rückwand 9 des Gehäuses 1 wird der Lichtquellenträger 7 an einem rückwärtigen Griffelement 30 durch eine geeignete Handhabungseinrichtung erfasst - dies kann auch manuell erfolgen- , mit der Lichtquelle 2 durch die Öffnung des Adapters 8 eingesteckt, bis eine Verrastung mit demselben erfolgt. Sodann wird die durch den Lichtquellenträger 7 und den Adapter 8 gebildete Baueinheit in Montagerichtung 18 in die Öffnung der Rückwand 9 des Gehäuses 1 eingesetzt, bis eine Verrastung des Adapters 8 mittels der Rastnasen 10 mit der Rückwand 9 des Gehäuses 1 erfolgt. Die Montage erfolgt daher auf einfache Weise durch Bewegen der Baueinheit in eine Längsrichtung.The light source carrier 7 has guide elements 27, so that it with the exception of the locking lugs 24 fit through the annular adapter 8 with the Receptacle 23 can be inserted therethrough until a flange 28 of the light source carrier 7 abuts an annular surface 29 of the adapter 8. With engagement of the flange 28 to the annular surface 29 of the adapter 8, the latching of the latching lugs 24 takes place, so that a secure mechanical connection between the light source carrier 7 and the adapter 8 is made. Preferably, the light source 2 is inserted into the receptacle 23 of the light source carrier 7 before the light source carrier 7 is inserted into the adapter 8. For mounting the light source 2 to the rear wall 9 of the housing 1, the light source carrier 7 is attached to a rear handle element 30 by a suitable handling device detected - this can also be done manually-, with the light source 2 inserted through the opening of the adapter 8 until it is latched to the same. Then, the unit formed by the light source carrier 7 and the adapter 8 is inserted in the mounting direction 18 in the opening of the rear wall 9 of the housing 1 until a locking of the adapter 8 by means of the locking lugs 10 with the rear wall 9 of the housing 1. The assembly is therefore carried out in a simple manner by moving the assembly in a longitudinal direction.

Alternativ könnte der Adapter 8 auch zuerst in die Öffnung der Rückwand 9 eingesetzt sein, wonach der Lichtquellenträger 7 in die Öffnung des Adapters 8 eingesetzt wird.Alternatively, the adapter 8 could also be first inserted into the opening of the rear wall 9, after which the light source carrier 7 is inserted into the opening of the adapter 8.

Damit ein zur Kontaktierung lagerichtiges Einsetzen des Lichtquellenträgers 7 in den Adapter 8 gewährleistet ist, weist der Adapter 8 auf der Innenseite 19 gegenüberliegende Einkerbungen 31 auf, die als Verwechslungsschutz dienen.In order to ensure correct contact for insertion of the light source carrier 7 into the adapter 8, the adapter 8 has on the inside 19 opposite notches 31, which serve as confusion protection.

Die Lichtquelle 2 kann als Glühlampe oder Leuchtdiode ausgebildet sein.The light source 2 may be formed as a light bulb or light emitting diode.
