Description
Die Erfindung betrifft eine Leuchte einem in einem Lampengehäuse untergebrachten, ggf. beweglichen Reflektor und einer die Lampe aufnehmenden Fassung, mit einem außerhalb des Lampengehäuses betätigbaren Schalter, wobei die Fassung an einer in das Lampengehäuse eingesetzten Platte befestigt ist, und wobei das Lampengehäuse auf seiner der Abstrahlseite entgegengesetzt liegenden Seite eine mittels eines Dekkels verschließbare Öffnung aufweist, durch die die Platte ins Innere des Lampengehäuses einschiebbar ist.The invention relates to a lamp housed in a lamp housing, possibly movable reflector and a lamp holder socket, with a switch that can be actuated outside the lamp housing, the socket being fastened to a plate inserted into the lamp housing, and the lamp housing on its The opposite side of the radiation side has an opening that can be closed by means of a cover, through which the plate can be inserted into the interior of the lamp housing.
Eine Leuchte, die mit einem in einem Lampengehäuse untergebrachten Reflektor und einem die Lampe aufnehmenden Sockel und mit einem von außerhalb des Lampengehäuses betätigbaren Schalter zum Einschalten der Lampe versehen ist, ist beispielsweise durch die CEAG-Leuchte, Typ BWE 6.1 bekannt geworden.A lamp which is provided with a reflector accommodated in a lamp housing and a base which receives the lamp and with a switch which can be actuated from outside the lamp housing to switch on the lamp has become known, for example, from the CEAG lamp, type BWE 6.1.
Eine der Leuchte der eingangs genannten Art ist aus der EP 0 301 236 A2 bekannt geworden. Diese Leuchte besitzt ein Leuchtengehäuse, das aus einem Strangpreßprofil abgeschnitten werden kann, wobei das Gehäuse auf einer Seite mit einer transparenten Scheibe und auf der anderen Seite mittels eines Deckels verschlossen werden kann. Innerhalb des Gehäuses an der Innenseite befinden sich Nuten, die in Abstand von 120° gegeneinander versetzt sind. Von der Seite aus, die mittels des Dekkels verschlossen wird, wird eine Chassisebene eingesetzt, an der ein Hitzeschild befestigt ist, der das Leuchtengehäuse axial in zwei Räume unterteilt und auf der Lampenseite einen Sockel mit eingesetzter Lampe trägt. Auf der Chassisebene ist weiterhin ein Vorschaltgerät befestigt, und die Chassisebene ist mittels einer von außen betätigbaren Schraube axial verschiebbar, wobei in besonderen Fällen die Schraube nicht vorhanden ist, dann müssen andere Befestigungselemente für die Chassisebene gefunden werden. Wegen der jeweils um 120° versetzten Nuten an der Innenseite bedarf besonderer Befestigungselemente für die Chassisebene; ein einfaches Einschieben in zwei sich gegeneinanderliegende Nuten erscheint nicht ohne weiteres möglich. Weiterhin ist nicht angegeben, wo sich ein evtl. Schalter befinden könnte. Eine Andeutung, daß der Schalter innerhalb des Leuchtengehäuses vorhanden ist, ist nicht gegeben.One of the luminaires of the type mentioned at the outset has become known from EP 0 301 236 A2. This lamp has a lamp housing that can be cut from an extruded profile, the housing can be closed on one side with a transparent pane and on the other side with a cover. There are grooves inside the housing on the inside, which are offset by 120 ° from each other. From the side that is closed by means of the cover, a chassis level is used, to which a heat shield is attached is that axially divides the luminaire housing into two rooms and carries a base with an inserted lamp on the lamp side. A ballast is also attached to the chassis level, and the chassis level is axially displaceable by means of an externally operable screw, the screw not being present in special cases, then other fastening elements for the chassis level must be found. Because of the 120 ° offset grooves on the inside, special fastening elements are required for the chassis level; a simple insertion into two mutually opposing grooves does not appear to be easily possible. Furthermore, it is not specified where a switch might be located. There is no indication that the switch is inside the luminaire housing.
Aus der FR 2 627 612 ist eine Leuche bekannt geworden, die ein topfförmiges Gehäuse aufweist, welches im Boden eine Öffnung aufweist, in die eine Lampe eingesetzt und darin gehaltert ist. Der Boden ist von außen mittels einer transparenten Abdeckkappe überdeckt. In das Innere des topfförmigen Gehäuses ist eine Leiterplatte eingesetzt, die elektronische Bauteile trägt; die offene Seite ist mittels einer Verschlußplatte abgedeckt und darüberhinaus noch mit einer Verschlußkappe, durch die elektrische Leiter der Leuchte zugeführt werden. Die Lampe wird nicht von der Leiterplatte gehaltert, da die Lampenfassung im Boden des Gehäuses vorhanden ist. Auch ist ein Schalter nicht dargestellt.From FR 2 627 612 a lamp has become known which has a pot-shaped housing which has an opening in the bottom into which a lamp is inserted and held therein. The bottom is covered from the outside by means of a transparent cover cap. In the interior of the pot-shaped housing, a circuit board is used, which carries electronic components; the open side is covered by a closure plate and moreover with a closure cap through which electrical conductors of the lamp are fed. The lamp is not supported by the circuit board because the lamp holder is in the bottom of the housing. A switch is also not shown.
Aufgabe der Erfindung ist es, eine Leuchte der eingangs genannten Art zu schaffen, bei der der Austausch der Lampe und evtl. auch bestimmter elektrischer Komponenten innerhalb des Lampengehäuses vereinfacht ist.The object of the invention is to provide a lamp of the type mentioned, in which the replacement of the lamp and possibly also certain electrical components within the lamp housing is simplified.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Platte als Leiterplatte ausgebildet ist, auf der die Fassung und der von außerhalb betätigbare Schalter unmittelbar befestigt sind, und daß die elektrischen Verbindungen zwischen dem Schalter und der Lampe sowie zu Anschlußklemmen am Lampengehäuse durch auf der Leiterplatte befindliche Leiterbahnen erzeugt sind.This object is achieved in that the plate is designed as a circuit board on which the socket and the switch operable from the outside are directly attached, and that the electrical connections between the switch and the lamp and to terminals on the lamp housing by located on the circuit board Traces are generated.
Auf diese Weise ist der Austausch einer Lampe erheblich vereinfacht. Man muß nur noch den Deckel öffnen und die Leiterplatte herausziehen, um die Lampe auszutauschen.In this way, the replacement of a lamp is considerably simplified. You just have to open the lid and pull out the circuit board to replace the lamp.
Eine vorteilhafte Ausgestaltung der Erfindung kann dahin gehen, daß das Lampengehäuse seitlich zur Abstrahlrichtung eine durch eine transparente Platte dicht verschlossene weitere Öffnung aufweist, durch welche ein auf einer in das Lampengehäuse von hinten einschiebbaren weiteren Leiterplatte angebrachte Anzeigedisplay sichtbar ist.An advantageous embodiment of the invention can be such that the lamp housing has a further opening that is sealed by a transparent plate laterally to the direction of radiation, through which an additional display mounted on a circuit board that can be inserted into the lamp housing from behind is visible.
Eine weitere vorteilhafte Ausgestaltung der Erfindung kann dahin gehen, daß die Kupplung zwischen dem Schalter und einem außerhalb des Lampengehäuses befindlichen Schaltgriffs in ihrer Längsrichtung und quer zur Einschieberichtung der Leiterplatte geteilt ist, dergestalt, daß die Kupplung beim Herausziehen der Leiterplatte nicht erst gelöst werden muß.A further advantageous embodiment of the invention can be such that the coupling between the switch and a switching handle located outside the lamp housing is divided in its longitudinal direction and transversely to the direction of insertion of the circuit board in such a way that the coupling does not have to be released when the circuit board is pulled out.
Zu diesem Zweck befindet sich an dem Schaltgriff ein Fortsatz, der angenähert einen Halbkreisquerschnitt besitzt; dieser Halbkreisquerschnitt wird zu einem Vollkreisquerschnitt ergänzt durch einen Fortsatz am Schalter, wobei die Trennebene zwischen diesen beiden Fortsätzen dergestalt angeordnet ist, daß eine Kraftübertragung vom Handgriff auf den Schalter möglich ist, die beiden Fortsatzabschnitte aber beim Herausziehen der Leiterplatte voneinander getrennt werden können.For this purpose there is an extension on the control handle, which has approximately a semicircular cross section; this semicircular cross section becomes a full circle cross section supplemented by an extension on the switch, the parting plane between these two extensions being arranged such that a power transmission from the handle to the switch is possible, but the two extension sections can be separated from one another when the circuit board is pulled out.
Eine weitere Ausgestaltung der Erfindung kann insbesondere dann, wenn das Lampengehäuse nach vorn in Lichtabstrahlrichtung mittels einer klar transparenten Scheibe verschlossen ist, dahin gehen, daß am Gehäuse eine nach innen vorspringende, gegen die vordere Fläche der Scheibe federnd zum Anliegen gelangende Lippe angeformt ist, die als Dichtlippe für die Abdichtung zwischen dem Gehäuse und dem Reflektorraum dient.A further embodiment of the invention can, in particular, if the lamp housing is closed at the front in the light emission direction by means of a clearly transparent pane, in that a lip is formed on the housing which projects inwards and resiliently abuts against the front surface of the pane serves as a sealing lip for the seal between the housing and the reflector space.
Wenn der Reflektor mit einem Drehring verbunden ist, mit dem der Reflektor in Lichtabstrahlrichtung bezogen auf die Lampe verstellbar ist, um beispielsweise die Abstrahlcharakteristik zu verändern, dann kann diese Dichtlippe an dem Drehring angeformt sein.If the reflector is connected to a rotating ring with which the reflector can be adjusted in relation to the lamp in the direction of light emission, for example in order to change the radiation characteristic, then this sealing lip can be integrally formed on the rotating ring.
Damit eine optimale Dichtung erzielt wird, bildet die an der Innenseite des Gehäuses oder Drehringes angeformte Lippe einen spitzen Winkel mit den Mantellinien der Innenfläche des Gehäuses oder des Drehringes; die radiale Dicke der Lippe wird dann zu ihrem freien Ende hin keilförmig sich verringern. Damit die Dichtlippe auch als Dichtlippe dient und wirkt, wird sie eine gewisse Elastizität besitzen. Ggf. kann der zwischen dem Reflektor, der Dichtlippenkante und dem Gehäuse bzw. dem Drehring gebildete Ringraum, der im Querschnitt dreieckförmig ist, zusätzlich mit einer Dichtmasse gefüllt sein.So that an optimal seal is achieved, the lip formed on the inside of the housing or rotating ring forms an acute angle with the surface lines of the inner surface of the housing or rotating ring; the radial thickness of the lip will then decrease in a wedge shape towards its free end. So that the sealing lip also serves and acts as a sealing lip, it will have a certain elasticity. Possibly. The annular space formed between the reflector, the sealing lip edge and the housing or the rotating ring, which is triangular in cross section, can additionally be filled with a sealing compound.

Es sei nun Bezug genommen auf die Figur 1.Reference is now made to FIG. 1.
Eine Lampe 10 besitzt ein Lampengehäuse 11, an dessen in der Zeichnung oben dargestelltem Abschnitt ein Handgriff 12 anschließt. Das Gehäuse 11 besitzt in der vorliegenden Form einen kreisförmigen Querschnitt und ist an seinem einen, in Lichtabstrahlrichtung hinteren Stirnende mittels eines Deckels 13 verschlossen, welcher einen Napfrand 14 aufweist, der von dem Gehäuse 11 mit einem vorspringenden Abschnitt 15 mit vergrößertem Innendurchmesser und gleichem Außendurchmesser unter Zwischenfügung einer Dichtung 16 umfaßt ist.A
Das andere vordere Stirnende besitzt einen Innengewindeabschnitt 17, in den ein Außengewindeabschnitt 18 eines Drehringes 19 eingeschraubt ist, der selbst wiederum ein Innengewinde 20 im Bereich des Außengewindeabschnittes 18 aufweist.The other front end has an
Der Drehring 11 besitzt an seinem dem Außengewindeabschnitt 18 entgegengesetzten, stirnseitigen Ende eine nach innen vorspringende Lippe 21, die umlaufend angeordnet ist und, unter einem Winkel alpha zur Mantellinie des Drehringes geneigt, in Richtung zum Innengewinde 20 vorspringt. Dadurch bildet die Lippe 21 einen federnden Absatz 22, gegen den eine vordere Glasscheibe 23 anliegt, die zusammen mit einer Zusatzscheibe 24, die eine zentrale, lupenartige Verdickung 25 aufweist, eine Art von Verbundglasscheiben bildet. An die Glasscheiben 23/24 schließt sich ein Reflektor 26 an, der an seinem freien Ende mit großem Durchmesser einen zylinderförmigen Fortsatz 27 aufweist, dessen Außendurchmesser dem Innendurchmesser des Drehringes, der dem Innendurchmesser des Gewindeabschnittes 20 entspricht, angepaßt ist. Der Übergang von dem zylinderförmigen Fortsatz 27 zu dem paraboloidförmigen Reflektorabschnitt 26a besitzt auf seiner Außenfläche eine radial verlaufende Stufung 28, gegen die ein Gewindering 29 mit einem Außengewinde anliegt, wenn der Gewindering 29 in das Innengewinde 20 eingeschraubt ist. Zwecks besseren Festschraubens besitzt der Gewindering 29 mindestens zwei sich gegenüberliegende, nach innen offene Nuten 30.The
Der Reflektor 26, der am Drehring 19 befestigt ist, umgibt einen Innenreflektor 31, der einen Stutzen 32 aufweist, der auf der entgegengesetzten Seite des Reflektorbereiches 33 von dieser aus vorspringt und dabei eine Zylinderform aufweist, deren Innendurchmesser dem Außendurchmesser des Sockels 34 einer Lampe 35 angepaßt ist. Der Innenreflektor mit dem Stutzen 32 ist auf einer Leiterplatte 36, siehe Figur 3, befestigt, an der auch ein Schalter 37 befestigt ist, der einen radial nach außen in Richtung zum Handgriff 12 weisenden, vorspringenden Schaltwellenabschnitt 38 aufweist, der mit einem parallel dazu verlaufenden, von einem Schaltgriff 40 nach innen vorspringenden Schaltwellenabschnitt 39 an diesem Schaltgriff 40 angekuppelt ist. Der Schaltgriff 40 ist in einer Vertiefung 41 drehbar gelagert, wobei der Boden der Vertiefung 41 mit einem Vorsprung 42 in eine erste Nut 43 und ein zylinderförmiger Vorsprung 44 in eine Nut 45 eingreift, und wobei der Schaltwellenabschnitt 39 unter Zwischenfügung einer Dichtung 46 eine Öffnung 47 im Gehäuse 11 durchgreift.The
Die Figur 1 zeigt, daß zwei Varianten zum Einsetzen von Nebenlampen 50 und 51 vorgesehen sein können. Bei der ersten, oberhalb der Schnittlinie II-II gezeichneten Variante (siehe auch Figur 3) besitzt der Innenreflektor 33 einen parallel zum Stutzen 32 verlaufenden Nebenstutzen 52, in dem die Nebenlampe 50 aufgenommen ist; bei der zweiten Variante (in Figur 3 nicht dargestellt) ist die Nebenlampe 51 in einen Nebenreflektor 53 eingesetzt, der eine ellipsoide Kontur aufweist; das von dem Nebenreflektor 53 reflektierte Licht wird durch eine Öffnung 44 im Innenreflektor 33 bzw. im Reflektorabschnitt 33 hindurch nach außen abgestrahlt.FIG. 1 shows that two variants for inserting
Aus Figur 2 ist ersichtlich, daß der Stutzen 32 an der Leiterplatte 36 mittels Nieten 55, 56 und der Schalter 37 auf nicht näher dargestellte Weise an der Leiterplatte 36 befestigt sind. Zur Bildung einer elektrisch-leitenden Verbindung zwischen der Lampe 35 und weiteren, nicht näher dargestellten Leitungsanschlüssen ist auf der Seite der Leiterplatte 36, auf der sich der Stutzen 32 befindet, eine L-förmige Kontaktdruckfeder 57 befestigt, deren einer Schenkel parallel zur Leiterplatte 36 und deren anderer Schenkel in Form eines federnden Kontaktelementes senkrecht dazu verläuft und mit einem der Kontaktstücke der Lampe 35 in Kontaktierung gelangt. Die Leiterbahnen auf der Leiterplatte verbinden dann das federnde Kontaktelement mit dem einen Kontaktstück des Schalters 37.From Figure 2 it can be seen that the
Zum Einschieben der Leiterplatte 36 besitzt das Gehäuse 11 zwei sich gegenüberliegende Rillen 58 und 59, die die Leiterplatte 36 aufnehmen und führen.To insert the
Neben den Rillen 58 und 59 sind weitere Rillen 60, 60a und 61, 61a bzw. 62 und 63 vorgesehen, in die weitere Leiterplatten 64, 64a und 65 eingesetzt werden können.In addition to the
An der Leiterplatte 65 ist ein Träger 66 befestigt, an dem ein napfförmiger Behälter 67 zur Aufnahme eines Elektronikdisplays 68 befestigt ist; in einem Gehäusevorsprung, der von dem Gehäuse 11 nach innen vorspringt, ist mittels eines Dichtelementes 70 eine Scheibe 71 eingesetzt, durch die das Display 68 sichtbar ist. Die Anordnung derartiger Fenster ist an sich bekannt, insbesondere auch ist bekannt, daß bei explosionsgeschützten Leuchten derartige Fenster abgedichtet sein müssen, so daß hier nicht näher darauf eingegangen werden soll.A
Für die vorliegende Erfindung ist lediglich erforderlich, anzugeben, daß eine Scheibe 71 vorgesehen ist, durch die ein Anzeigedisplay 68 sichtbar ist.For the present invention, it is only necessary to indicate that a
Die Lippe 21 ist aufgrund ihrer sich geringfügig verjüngenden Kontur federnd ausgebildet, so daß die Lippe 21 bei entsprechender Vorspannkraft, die durch den Gewindering 29 erzeugt wird, als Dichtung dienen kann. Zusätzlich könnte in den V-förmigen oder im Querschnitt dreieckförmigen Abschnitt 21a, den die Dichtlippe 21 aufgrund ihrer Form mit dem übrigen Drehring-Bereich und der Scheibe 23 bildet, mit einer Dichtmasse (21b) ausgegossen sein.The
Die beiden Schaltwellenabschnitte 38 und 39 sind so ausgebildet, daß im montierten Zustand, wie in Figur 1 dargestellt, beide Schaltwellenabschnitte miteinander gekuppelt sind, wogegen im ausgeschalteten Zustand des Schalters eine leichte Demontage, d. h. ein leichtes Herausziehen der Leiterplatte 36 mit dem Schalter 37 und dem Innenreflektor 33 mit dem Stutzen 32 möglich ist.The two
Der Ring 19 besitzt an seinem Außenumfang eine am Umfang verlaufende Vertiefung 72, in die eine durch das Gehäuse 11 hindurchgeschraubte Schraube 73 eingreift; wenn der Drehring 19 und damit der Reflektor 26 verdreht wird, was zu einer Lageveränderung des Brennpunktes des Reflektors führt, dann schlägt die Schraube 73 an die in Umfangsrichtung in Abstand zueinander angeordneten Enden der Vertiefung 72 an, wodurch ein weiteres Verdrehen des Drehringes unmöglich wird. Daß die Schraube 73 und die Vertiefung 72 vorgesehen sein müssen, liegt daran, daß die Leuchte in explosionsgefährdeten Bereichen eingesetzt werden soll. Zu diesen Zwecken darf beispielsweise der durch das Gewinde 18/17 gebildete Luftspalt zwischen dem Gehäuse 11 und dem Drehring 19 durch Verdrehen des Drehrings 19 nicht so weit verkleinert werden, daß bei einer Explosion im Inneren des Gehäuses heiße Gase nach außen treten können. Die beiden Anschläge in der Vertiefung 72 verhindern, daß der Drehring 19 nur so weit herausgezogen bzw. herausgedreht werden kann, daß der Luftspalt immer ausreichend ist.The
