Description

Die Erfindung betrifft eine Kaltlichtspiegelleuchte nach dem Oberbegriff des Anspruches 1.The invention relates to a cold light mirror lamp according to the preamble of claim 1.

Bei einer im Handel befindlichen Kaltlichtspiegelleuchte ist die Austrittsöffnung des Spiegelreflektors durch ein Deckglas verschlossen, das fest und unlösbar mit dem Spiegelreflektor verbunden ist. Das Deckglas bildet einerseits einen Schutz für die Lampe und die Innenseite des Spiegelreflektors und andererseits einen Unfallschutz, indem es ein Berühren der im eingeschalteten Zustand besonders heißen Lampe verhindert. Aufgrund der unlösbaren Verbindung von Spiegelreflektor und Deckglas muß bei einem Defekt der Lampe oder einer Beschädigung des Spiegelreflektors bzw. des Deckglases die gesamte Baugruppe aus Spiegelreflektor, Lampe und Deckglas ausgewechselt werden.In the case of a cold light mirror lamp commercially available, the exit opening of the mirror reflector is closed by a cover glass which is firmly and permanently connected to the mirror reflector. The cover glass on the one hand provides protection for the lamp and the inside of the mirror reflector and, on the other hand, protection against accidents by preventing the lamp, which is particularly hot when it is switched on, from touching. Due to the inseparable connection of the mirror reflector and cover glass, the entire assembly of mirror reflector, lamp and cover glass must be replaced if the lamp is defective or the mirror reflector or cover glass is damaged.

Bei einer anderen im Handel befindlichen, ebenfalls mit einem Deckglas versehenen Kaltlichtspiegelleuchte ist das Deckglas mit Hilfe eines aus Blech gefertigten Halteringes lösbar am wulstförmigen Rand des Spiegelreflektors angebracht, indem entweder mehrere durch Einschnitte am Haltering gebildete Lappen um den wulstförmigen Rand umgebogen werden oder der Haltering mit Hilfe zweier durch entsprechende Bohrungen des Halteringes hindurchgesteckte Federbügel mit einer Leuchtenhalterung verbunden wird. Dem Vorteil der lösbaren Verbindung zwischen Spiegelreflektor und Deckglas steht der Nachteil des erhöhten technischen Aufwandes, insbesondere bei der zweiten Version mit den Federbügeln gegenüber.In another commercially available cold light mirror luminaire, which is also provided with a cover glass, the cover glass is detachably attached to the bead-shaped edge of the mirror reflector with the aid of a holding ring made of sheet metal, either by bending several flaps formed by incisions on the holding ring around the bead-shaped edge or the holding ring with Is connected to a lamp holder with the aid of two spring clips inserted through corresponding holes in the retaining ring. The advantage of the detachable connection between the mirror reflector and the cover glass is offset by the disadvantage of the increased technical outlay, particularly in the case of the second version with the spring clips.

Der Erfindung liegt die Aufgabe zugrunde, eine mit einem Deckglas versehene Kaltlichtspiegelleuchte zu schaffen, bei der das Deckglas auf einfache Weise am Spiegelreflektor anbringbar und wieder entfernbar ist. Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The invention has for its object to provide a cold light mirror lamp provided with a cover glass, in which the cover glass can be easily attached to the mirror reflector and removed again. The object is achieved by the characterizing features of claim 1.

Durch die Maßnahme, das Deckglas über eine unmittelbare kraftschlüssige Verbindung lösbar mit dem Spiegelreflektor zu verbinden, läßt sich das Deckglas ohne weitere Hilfs- oder Haltemittel am Spiegelreflektor anbringen und bei Bedarf wieder entfernen, so daß eine lösbar im Spiegelreflektor angeordnete Lampe bei einem Defekt ausgewechselt oder auch der Spiegelreflektor bzw. das Deckglas im Falle einer Beschädigung einzeln ausgetauscht werden können.The measure of releasably connecting the cover glass to the specular reflector via a direct non-positive connection enables the cover glass to be attached to the specular reflector without further aids or holding means and removed again if necessary, so that a lamp which is detachably arranged in the specular reflector is replaced in the event of a defect or the mirror reflector or cover glass can also be replaced individually in the event of damage.

Gemäß den Ansprüchen 2 bis 5 ist die unmittelbare kraftschlüssige Verbindung als eine Bajonett- oder als eine Schraubverbindung ausgebildet, wobei ein Teil der Verbindungselemente am Deckglas und der mit diesen korrespondierende andere Teil der Verbindungselemente am Spiegelreflektor ausgebildet ist.According to claims 2 to 5, the direct non-positive connection is designed as a bayonet or as a screw connection, part of the connecting elements being formed on the cover glass and the other part of the connecting elements corresponding thereto being formed on the specular reflector.

Gemäß Anspruch 6 ist dem Spiegelreflektor eine beliebige Anzahl von Deckgläsern zugeordnet, die sich hinsichtlich ihrer optischen und/oder farblichen Eigenschaften unterscheiden und gegeneinander austauschbar sind, um den Abstrahlwinkel und/oder den Farbcharakter der Leuchte zu verändern.According to claim 6, the mirror reflector is assigned any number of cover glasses, which differ in terms of their optical and / or color properties and are interchangeable in order to change the beam angle and / or the color character of the lamp.

Die Erfindung ist anhand von drei in der Zeichnung dargestellten Ausführungsbeispielen erläutert. Es zeigen:

  • Fig. 1 eine Schnittdarstellung einer Kaltlichtspiegelleuchte und eines Deckglases, das über eine Bajonettverbindung mit dem Spiegelreflektor verbindbar ist;
  • Fig. 2 die Kaltlichtspiegelleuchte und das Deckglas aus Fig. 1 in einer anderen Sicht;
  • Fig. 3 eine vergrößerte Darstellung der Verbindungselemente einer alternativen Bajonettverbindung und
  • Fig. 4 eine Anzahl einer Kaltlichtspiegelleuchte und eines Deckglases, das über ein Gewinde mit dem Spiegelreflektor verbindbar ist.
The invention is explained with reference to three exemplary embodiments shown in the drawing. Show it:
  • Figure 1 is a sectional view of a cold light mirror light and a cover glass, which can be connected to the mirror reflector via a bayonet connection.
  • FIG. 2 the cold light mirror lamp and the cover glass from FIG. 1 in a different view;
  • Fig. 3 is an enlarged view of the connecting elements of an alternative bayonet connection and
  • Fig. 4 shows a number of a cold light mirror light and a cover glass which can be connected to the mirror reflector via a thread.

Die Kaltlichtspiegelleuchte des ersten Ausführungsbeispieles besteht im wesentlichen aus einem Spiegelreflektor 1, einer Niedervoltlampe 2 und einem Deckglas 3.The cold light mirror luminaire of the first exemplary embodiment essentially consists of a specular reflector 1, a low-voltage lamp 2 and a cover glass 3.

In einem Ansatz 4 des Spiegelreflektors 1 ist ein Einsatz 5 aus einem elektrisch nicht leitfähigen Material einzementiert. In dem Einsatz 5 sind zwei Federklemmen 6 angeordnet, die je einen aus dem Einsatz 5 herausragenden Anschlußstift 7 aufweisen. Mit Hilfe der Anschlußstifte 7 läßt sich der Spiegelreflektor 1 mit einer nicht dargestellten Leuchtenfassung verbinden.An insert 5 made of an electrically non-conductive material is cemented into an attachment 4 of the mirror reflector 1. In the insert 5, two spring clips 6 are arranged, each having a connector pin 7 protruding from the insert 5. With the help of the connecting pins 7, the mirror reflector 1 can be connected to a lamp holder, not shown.

Zum Montieren der Lampe 2 werden deren Anschlußstifte 8 durch nicht näher bezeichnete Durchtrittsbohrungen des Einsatzes 5 hindurch in die Federklemmen 6 eingeschoben.To mount the lamp 2, its connecting pins 8 are inserted into the spring clips 6 through through bores of the insert 5, which are not specified.

Die Lampe 2 ist somit lösbar mit dem Spiegelreflektor 1 verbunden und kann ggf. ausgewechselt werden.The lamp 2 is thus detachably connected to the mirror reflector 1 and can be replaced if necessary.

Die Austrittsöffnung 9 des Spiegelreflektors 1 ist durch einen Wulstrand 10 begrenzt. Im Wulstrand 10 sind zwei Aussparungen 11 enthalten, von denen eine in Fig. 2 dargestellt ist.The outlet opening 9 of the mirror reflector 1 is delimited by a bead 10. Two recesses 11 are contained in the beaded edge 10, one of which is shown in FIG. 2.

Das Deckglas 3 besteht aus einer Glasscheibe 12 und zwei im wesentlichen L-förmigen Ansätzen 13, deren Anordnung und Breite an die Aussparungen 11 angepaßt sind.The cover slip 3 consists of a glass pane 12 and two essentially L-shaped shoulders 13, the arrangement and width of which are adapted to the cutouts 11.

Zur Montage des Deckglases 3 werden die Ansätze 13 durch die Aussparungen 11 hindurchgesteckt, woraufhin das Deckglas 3 mindestens so weit gedreht wird, daß die Ansätze 13 den Wulstrand 10 vollständig hintergreifen. Die Form und Tiefe der Ansätze 13 ist hierbei derart an die Form und Dicke des Wulstrandes 10 angepaßt, daß das Verdrehen des Deckglases 3 nur unter Überwindung eines Reibwiderstandes durchgeführt werden kann, so daß das Deckglas 3 mit Selbsthemmung am Spiegelreflektor 1 festsitzt.To mount the cover glass 3, the lugs 13 are inserted through the cutouts 11, whereupon the cover glass 3 is rotated at least to such an extent that the lugs 13 completely engage behind the beaded edge 10. The shape and depth of the lugs 13 are adapted to the shape and thickness of the bead 10 in such a way that the twisting of the cover glass 3 can only be carried out by overcoming a frictional resistance can, so that the cover slip 3 is self-locking on the mirror reflector 1.

Der mit den Aussparungen 11 versehene Wulstrand 10 bildet mit den Ansätzen 13 eine Bajonettverbindung 14.The bead 10 provided with the recesses 11 forms a bayonet connection 14 with the projections 13.

Bei der in Fig. 3 dargestellten alternativen Ausführungsform einer Bajonettverbindung 15 zwischen einem Spiegelrefelektor 16 und einem Deckglas 17 ist ein neben einer jeden Aussparung 18 im Wulstrand 19 befindlicher Abschnitt 20 des Wulstrandes 19 keilförmig ausgebildet. Die L-förmigen Ansätze 21 des Deckglases 17 sind entsprechend ausgebildet, indem eine hinter den Wulstrand 19 bzw. dessen Abschnitte 20 greifende Rippe 22 in entsprechender Weise keilförmig ausgebildet ist.In the alternative embodiment of a bayonet connection 15 shown in FIG. 3 between a mirror reflector 16 and a cover glass 17, a section 20 of the bead base 19 located next to each recess 18 in the bead base 19 is wedge-shaped. The L-shaped projections 21 of the cover glass 17 are formed accordingly by a rib 22 which engages behind the bead edge 19 or its sections 20 in a corresponding manner.

Bei der Bajonettverbindung 15 kann das Deckglas 17 aufgrund der keilförmig gestalteten Elemente 20 und 22 auf dem Spiegelreflektor 16 durch entsprechendes Drehen festgeklemmt werden, wodurch auch bei größeren Maßtoleranzen bezüglich der Dicke des Wulstrandes 19 und der Tiefe der Ansätze 21 eine sichere Verbindung des Deckglases 17 mit dem Spiegelreflektor 16 gewährleistet ist.In the case of the bayonet connection 15, the cover glass 17 can be clamped on the specular reflector 16 due to the wedge-shaped elements 20 and 22, so that even with larger dimensional tolerances with regard to the thickness of the bead 19 and the depth of the shoulders 21, the cover glass 17 is connected securely the mirror reflector 16 is guaranteed.

Bei dem Ausführungsbeispiel nach Fig. 4 ist auf dem Wulstrand 23 des Spiegelreflektors 24 ein Außengewinde 25 ausgebildet. Das Deckglas 26 besteht aus einer Glasscheibe 27 und einem sich axial erstreckenden Ring 28, an dessen Innenseite ein Innengewinde 29 ausgebildet ist. Bei diesem Ausführungsbeispiel wird das Deckglas 26 wie ein Schraubdeckel auf den Spiegelreflektor 24 aufgeschraubt. Die Gewindeelemente 25, 29 bilden eine Schraubverbindung 30.In the exemplary embodiment according to FIG. 4, an external thread 25 is formed on the bulge 23 of the mirror reflector 24. The cover glass 26 consists of a glass pane 27 and an axially extending ring 28, on the inside of which an internal thread 29 is formed. In this exemplary embodiment, the cover glass 26 is screwed onto the mirror reflector 24 like a screw cap. The threaded elements 25, 29 form a screw connection 30.

Bei den verschiedenen Ausführungsbeispielen kann die Glasscheibe 12 bzw. 27 wahlweise glatt und farblos transparent oder als optische Linse zur Erzielung eines bestimmten Abstrahlwinkels oder bzw. zusätzlich als farbiges Filter ausgebildet sein.In the various exemplary embodiments, the glass pane 12 or 27 can optionally be designed to be smooth and colorless transparent or as an optical lens to achieve a specific radiation angle or as a colored filter.
