Description

Die Erfindung bezieht sich auf eine Leuchte für eine stab­förmige, an beiden Enden mit Stiftsockeln versehene Leuchtstofflampe mit einem langgestreckten Trägerprofil, dessen Breite nur wenig größer oder kleiner als der Durch­messer des Lampenkolbens ist und an das sich beidseitig mit Fassungskontakten bestückte Fassungsgehäuse anschließen, die mit je einem Schlitz zur Aufnahme der Sockelstifte beim achsparallelen Einsetzen der Lampe versehen sind.The invention relates to a lamp for a rod-shaped fluorescent lamp provided at both ends with pin bases with an elongated support profile, the width of which is only slightly larger or smaller than the diameter of the lamp bulb and to which the socket housing, which is equipped with socket contacts on both sides, connects with each a slot for receiving the socket pins are provided when the lamp is inserted parallel to the axis.

Derartige Leuchten sind üblicherweise mit Fassungen ausge­stattet, in welche die Lampe mit ihren Sockelstiften achs­parellel eingesetzt wird, wonach durch eine Vierteldrehung der Lampe um ihre Längsachse eine Arretierung und Kontaktierung der Sockelstifte mit den Fassungskontakten erfolgt. Soll die Leuchte jedoch aus formalen Gründen sehr schmal ausgebildet, d.h. in ihrer Breite nur wenig größer oder sogar kleiner als der Durchmesser des Lampenkolbens sein, so können handelsübliche Lampenfassungen nicht mehr eingesetzt werden, da sich diese nicht so klein herstellen lassen.Such lights are usually equipped with sockets, in which the lamp with its base pins is used axially parallel, after which a locking and contacting of the base pins with the socket contacts takes place by a quarter turn of the lamp about its longitudinal axis. However, if the luminaire is designed to be very narrow for formal reasons, i.e. their width can be only slightly larger or even smaller than the diameter of the lamp bulb, so standard lamp holders can no longer be used because they cannot be produced so small.

Aus der EP-PS 12 234 ist eine Leuchte für eine stabförmige Leuchtstofflampe mit einem langgestreckten Trägerprofil bekannt, dessen Breite in der Größenordnung des Lampen­kolbens liegt. Zum Einsetzen bzw. Auswechseln der Lampe sind die Fassungsgehäuse gegenüber dem Trägerprofil in Achsrichtung verschiebbar angeordnet, d.h. die Fassungs­gehäuse lassen sich aus ihrer normalen Betriebsstellung axial so weit nach außen in eine gerastete Stellung verschieben, daß die Leuchtstofflampe ohne weiter Maßnahmen einsetzbar bzw. herausnehmbar ist. Unabhängig davon, daß es sich hierbei um eine relativ aufwendige Konstruktion handelt, benötigt die bekannte Leuchte einen großen Platzbedarf in Längsrichtung. Eine Lichtband­anordnung ist hiermit nicht möglich.From EP-PS 12 234 a lamp for a rod-shaped fluorescent lamp with an elongated support profile is known, the width of which is in the order of the lamp bulb. To insert or replace the lamp, the socket housings are arranged to be displaceable in the axial direction with respect to the carrier profile, ie the socket housings can be moved axially outwards from their normal operating position into a locked position move that the fluorescent lamp can be used or removed without further measures. Regardless of the fact that this is a relatively complex construction, the known lamp requires a large amount of space in the longitudinal direction. A light band arrangement is not possible with this.

Der Erfindung liegt daher die Aufgabe zugrunde, eine kostengünstige Leuchte mit einem schmalen Trägerprofil zu schaffen, bei der zum achsparallelen Einsetzen der Lampe in die Fassungsgehäuse diese gegenüber dem Trägerprofil in einer festen Stellung verbleiben.The invention is therefore based on the object of providing an inexpensive luminaire with a narrow support profile, in which the lamp remains in a fixed position in relation to the support profile for the axially parallel insertion of the lamp into the holder housing.

Diese Aufgabe wird bei einer Leuchte eingangs erwähnter Art gemäß der Erfindung dadurch gelöst, daß auf die Lampensockel Zwischenstücke aus Isoliermaterial aufgesetzt sind, die auf ihrer Rückseite je einen sich prallel zu den Sockelstiften erstreckenden Quersteg aufweist, der derart geformt ist, daß die einzelnen Sockelstifte auf verschiedenen Seiten des Quersteges liegen, und der beim Einsetzen der Lampe in die Leuchte in den Schlitz eines Fassungsgehäuses verriegelnd eingreift, wobei die Sockel­stifte mit den Fassungskontakten in Verbindung kommen.This object is achieved in a lamp of the type mentioned according to the invention in that intermediate pieces made of insulating material are placed on the lamp base, each of which has on its back a transverse web extending parallel to the base pins, which is shaped such that the individual base pins on lie on different sides of the crossbar, and which engages when the lamp is inserted into the lamp in the slot of a socket housing, the socket pins coming into contact with the socket contacts.

Hierbei wird die Lampe mit Hilfe der auf die Lampensockel aufgesetzten Zwischenstücke in den Fassungsgehäusen gehaltert, ohne daß diese gegenüber dem Trägerprofil in Achsrichtung verschoben werden müssen. Die Länge der Leuchte wird somit zum Auswechseln der Lampe nicht geändert. Durch die Anordnung der einzelnen Sockelstifte der Lampe auf verschiedenen Seiten des Quersteges der Zwischenstücke werden die Sicherheitsvorschrfiten erfüllt, wonach keiner der beiden Sockelstifte berührbar sein darf, wenn der andere Stift bereits in elektrischer Verbindung mit einem der Fassungskontakte steht. Vorzugsweise ist hierfür der Quersteg in seinem Querschnitt S-förmig ausge­bildet.Here, the lamp is held in the socket housing with the aid of the intermediate pieces placed on the lamp base, without these having to be displaced in the axial direction relative to the carrier profile. The length of the lamp is therefore not changed to replace the lamp. The arrangement of the individual socket pins of the lamp on different sides of the crosspiece of the intermediate pieces fulfills the safety requirements according to which neither of the two socket pins may be touchable if the other pin is already in electrical connection with one of the socket contacts. For this purpose, the cross bar is preferably S-shaped in its cross section.

Zur besseren Halterung der Zwischenstücke in den Fassungs­gehäusen kann der Quersteg der Zwischenstücke am Oberrand eine Verbreiterung aufweisen, welche in den Schlitz des Fassungsgehäuses deckelartig einrastet.To better hold the intermediate pieces in the socket housings, the crossbar of the intermediate pieces can have a widening at the upper edge, which snaps into the slot of the socket housing like a lid.

Damit auch bei unsachgemäßer Handhabung der Lampe, z.B. bei dem Versuch, die Lampe ohne Zwischenstücke in die Fassungsgehäuse einzusetzen, keine Kontaktmöglichkeit eines der Lampenstifte gegeben wird, besitzen gemäß einer vorteilhaften Weiterbildung der Leuchte nach der Erfindung die Zwischenstücke zum Einstecken der beiden Sockelstifte je zwei Kontakthülsen, welche in ihrer Länge über die Sockelstifte hinausragen und dort mit den entsprechend tief im Fassungsgehäuse untergebrachten Fassungskontakten zusammenwirken. Hierbei liegen die Fassungskontakte derart tief in den Fassungsgehäusen, daß beim Einsetzen einer Lampe ohne Zwischenstücke deren relativ kurze Sockelstifte die Fassungskontakte nicht erreichen können.So even if the lamp is handled improperly, e.g. in an attempt to insert the lamp into the socket housing without intermediate pieces, no contact possibility of one of the lamp pins is given, according to an advantageous development of the lamp according to the invention, the intermediate pieces for inserting the two socket pins each have two contact sleeves, which protrude in length beyond the socket pins and there interact with the socket contacts, which are located deep in the socket housing. Here, the socket contacts are so deep in the socket housings that when a lamp is inserted without spacers, its relatively short base pins cannot reach the socket contacts.

Um die beiden Lampensockel vollständig abzudecken, besitzt gemäß einer weiteren vorteilhaften Ausführungsform der Leuchte nach der Erfindung jedes Zwischenstück an seiner Vorderseite eine den Lampensockel aufnehmende Zylinder­hülse.In order to completely cover the two lamp bases, according to a further advantageous embodiment of the lamp according to the invention, each intermediate piece has on its front side a cylinder sleeve which receives the lamp base.

Ein Ausführungsbeispiel nach der Erfindung wird nunmehr anhand der Zeichnung näher erläutert. Es zeigen:

An embodiment of the invention will now be explained in more detail with reference to the drawing. Show it:
  • 1 is a side view of a lamp with a fluorescent lamp arranged above it axially, on the base of which intermediate pieces are placed,
  • 2 is a perspective view of a socket housing (partly in section) with an intermediate piece that can be placed on a fluorescent lamp before it is inserted into the socket housing,

  • 5 shows a cross section through this intermediate piece along the plane VV of FIG. 4th

Die Leuchte nach Fig. 1 besitzt ein langgestrecktes rinnenförmiges Trägerprofil 1, an das sich beidseitig Fassungsgehäuse 2 aus z.B. Kunststoff anschließen. Die Leuchte dient zur Aufnahme einer stabförmigen, an beiden Enden mit Stiftsockeln 3 versehenen Leuchtstofflampe 4 (vgl. Fig. 2). Die beiden Stiftsockel 3 der Leuchtstoff­lampe 4 besitzen jeweils zwei Sockelstifte 5. In dem Trägerprofil 1, dessen Breite nur wenig größer oder kleiner als der Durchmesser des Glaskolbens der Lampe 4 ist, können die für den Betrieb der Leuchtstofflampe 4 benötigten Vorschaltgeräte, wie Drosselspule, Starter und gegebenenfalls Temperatursicherung (in der Zeichnung nicht dargestellt), untergebracht werden. Wird die Lampe 4 mit einem elektronischen Vorschaltgerät betrieben, so kann dieses in eines der Fassungsgehäuse 2 eingebaut werden. In einem der Fassungsgehäuse 2 ist ein elektrischer Schalter 6 zum Ein- und Ausschalten der Lampe 4 unterge­bracht. Wie aus Fig. 2 hervorgeht, ist jedes Fassungs­gehäuse 2 mit einem Schlitz 7 zur Aufnahme der Sockel­stifte 5 versehen. In den Fassungsgehäusen 2 sind Fassungskontakte 8 vorgesehen, die übereinander angeordnet sind.The lamp according to Fig. 1 has an elongated channel-shaped support profile 1, on which both sides of the socket housing 2 made of e.g. Connect plastic. The lamp serves to accommodate a rod-shaped fluorescent lamp 4 provided with pin bases 3 at both ends (cf. FIG. 2). The two pin bases 3 of the fluorescent lamp 4 each have two base pins 5. In the carrier profile 1, the width of which is only slightly larger or smaller than the diameter of the glass bulb of the lamp 4, the ballasts required for the operation of the fluorescent lamp 4, such as a choke coil, starter and, if necessary, thermal fuse (not shown in the drawing). If the lamp 4 is operated with an electronic ballast, this can be installed in one of the socket housings 2. An electrical switch 6 for switching the lamp 4 on and off is accommodated in one of the socket housings 2. As can be seen from FIG. 2, each socket housing 2 is provided with a slot 7 for receiving the socket pins 5. In the socket housing 2 socket contacts 8 are provided, which are arranged one above the other.

Auf die Lampensockel 3 werden Zwischenstücke 9 aus Isoliermaterial aufgesetzt, die in den Fig. 3 bis 5 näher dargestellt sind. Diese Zwischenstücke 9 bestehen aus einem plattenförmigen Kunststoffteil 10, der auf seiner Rückseite einen sich parallel zu den Sockelstiften 5 erstreckenden Quersteg 11 aufweist, der in seinem Quer­schnitt S-förmig ausgebildet ist (Fig. 5). Beim Einsetzen der mit den Zwischenstücken 9 versehenen Lampe 4 in Pfeil­richtung in die Leuchte dringen die Querstege 11 in die Schlitze 7 der Fassungsgehäuse 2 ein. Jeder Quersteg 11 besitzt an seinem Oberrand eine Verbreiterung 12, welche in die den Schlitz 7 umgebende Wand eines Fassungs­gehäuses 2 deckelartig einrastet, wodurch die Lampe 4 an der Leuchte gehaltert wird.Intermediate pieces 9 made of insulating material are placed on the lamp base 3 and are shown in more detail in FIGS. 3 to 5. These intermediate pieces 9 consist of a plate-shaped plastic part 10, which has on its rear side a transverse web 11 which extends parallel to the base pins 5 and which has an S-shaped cross section (FIG. 5). When the lamp 4 provided with the intermediate pieces 9 is inserted into the lamp in the direction of the arrow, the transverse webs 11 penetrate into the slots 7 in the socket housing 2. Each crossbar 11 has at its upper edge a widening 12 which snaps into the cover 7 surrounding the slot 7 wall of a lampholder housing 2, whereby the lamp 4 is held on the lamp.

Wie aus Fig. 3 hervorgeht, besitzen die Zwischenstücke 9 zum Einstecken der beiden Sockelstifte 5 der Lampe 4 je zwei längsgeschlitzte Kontakthülsen 13, welche erheblich länger als die Sockelstifte 5 sind und sich jeweils auf verschiedenen Seiten des Quersteges 11 erstrecken (Fig. 5).As can be seen from FIG. 3, the intermediate pieces 9 each have two longitudinally slotted contact sleeves 13 for inserting the two socket pins 5 of the lamp 4, which are considerably longer than the socket pins 5 and each extend on different sides of the crosspiece 11 (FIG. 5).

An seiner Vorderseite besitzt jedes Zwischenstück 9 einen den Lampensockel 3 aufnehmende Zylinderhülse 14. Am Fuße der Zylinderhülse 14 sind zwei schlitzartige Aus­sparungen 15 vorgesehen, die zur Aufnahme einer isolierenden Abdeckscheibe 16 dienen (Fig. 3).On its front side each intermediate piece 9 has a cylinder sleeve 14 which receives the lamp base 3. At the foot of the cylinder sleeve 14 there are two slot-like recesses 15 which serve to receive an insulating cover plate 16 (FIG. 3).

Wie insbesondere aus den Fig. 1 und 4 hervorgeht, sind die Zwischenstücke 9 auf die Lampensockel 3 aufgesetzt, wobei die Lampensockel 3 von der Zylinderhülse 14 abgedeckt werden. Die Sockelstifte 5 der Lampe 4 dringen hierbei unter Bildung einer großen Kontaktfläche in die Kontakt­hülsen 13 ein. Anschließend wird die Lampe 4 mit den aufgesetzten Zwischenstücken 9 in Pfeilrichtung achs­parallel zum Trägerprofil 1 hin verschoben, wobei die Zwischenstücke 9 mit ihren Querstegen 11 in die Schlitze 7 der Fassungsgehäuse 2 eindringen, bis die Verbreiterungen 12 der Querstege 11 in der Wand der Fassungsgehäuse 2 einrasten und die Schlitze 7 deckelartig verschließen. Hierbei kommen die beiden Kontakthülsen 13, welche in ihrer Länge über die Sockelstifte 5 hinausragen, mit den tief im Fassungsgehäuse 2 untergebrachten Fassungskontakten 8 in Berührung, und zwar die in Fig. 2 untere Kontakthülse mit dem unteren Fassungskontakt und die obere Kontakthülse mit dem oberen Fassungskontakt. Hierdurch wird eine elektrische Verbindung von den Fassungskontakten 8 über die Kontakthülsen 13 zu den Sockelstiften 5 der Lampe 4 hergestellt. Da, wie insbe­sondere aus Fig. 5 hervorgeht, die beiden Kontakthülsen 13 auf verschiedenen Seiten des Quersteges 11 liegen, kann beim Einsetzen der Lampe 4 in die Fassungsgehäuse 2 jede Kontakthülse 13 nur jeweils mit dem ihr zugeordneten Fassungskontakt 8 in elektrische Verbindung kommen. Die Kontaktgabe zwischen den beiden Kontakthülsen 13 und ihren Fassungskontakten 8 geschieht somit gleichzeitig, wobei keine Berührung der Kontakte von außen möglich ist. - Das Herausnehmen oder Auswechseln der Lampe 4 geschieht in umgekehrter Reihenfolge.1 and 4, the intermediate pieces 9 are placed on the lamp base 3, the lamp base 3 being covered by the cylinder sleeve 14. The base pins 5 of the lamp 4 penetrate into the contact sleeves 13 to form a large contact area. Subsequently, the lamp 4 with the attached spacers 9 is displaced axially parallel to the support profile 1 in the direction of the arrow, the spacers 9 penetrating with their transverse webs 11 into the slots 7 of the socket housing 2 until the Snap the widenings 12 of the crossbars 11 into the wall of the socket housing 2 and close the slots 7 like a cover. Here, the two contact sleeves 13, which protrude in length beyond the base pins 5, come into contact with the socket contacts 8 housed deep in the socket housing 2, namely the lower contact sleeve in FIG. 2 with the lower socket contact and the upper contact sleeve with the upper socket contact . This creates an electrical connection from the socket contacts 8 via the contact sleeves 13 to the base pins 5 of the lamp 4. Since, as can be seen in particular from FIG. 5, the two contact sleeves 13 lie on different sides of the crossbar 11, when the lamp 4 is inserted into the socket housing 2, each contact sleeve 13 can only come into electrical connection with the socket contact 8 assigned to it. The contact between the two contact sleeves 13 and their socket contacts 8 thus occurs simultaneously, with no contact of the contacts from the outside being possible. - The removal or replacement of the lamp 4 is done in reverse order.
