Description
Die Ausführung von Leuchten für Gruben und andere explosionsgefährdete Betriebe unterliegt besonders strengen Vorschriften. Insbesondere die Leuchten mit röhrenförmigen Entladungslampen werden infolgedessen sehr schwer und teuer, auch sind sie in Bergwerken vor Ort infolge ihrer Größe kaum verwendbar.The execution of lights for pits and other potentially explosive Businesses are subject to particularly strict regulations. In particular the lights with As a result, tubular discharge lamps become very heavy and expensive, too they are hardly usable in on-site mines due to their size.
Es ist bereits bekannt, bei explosionsgeschützten Leuchten für Bergwerke wendelförmige Entladungslampen zu verwenden.It is already known for explosion-proof lights for mines to use helical discharge lamps.
Die Erfindung bezweckt die Schaffung einer Leuchte für rohrförmige Entladungslampen für explosionsgefährdete Betriebe, die auch in niedrigen Stollen und vor Ort verwendbar ist und mit wesentlich geringerem Aufwand hergestellt werden kann.The invention aims to create a lamp for tubular Discharge lamps for companies with a risk of explosion, also in low tunnels and can be used on site and can be produced with significantly less effort can.
Die Erfindung betrifft eine schlagwetter- und explosionsgeschützte Leuchte mit wendelförmiger Entladungslampe, insbesondere für Bergwerke, und besteht darin, daß die Entladungslampe in einen durchsichtigen Kunststoffkörper, vorzugsweise aus Kunstharz, eingegossen ist. Dadurch ist die Lampe gegen Bruch völlig gesichert, ohne daß ein besonderer Schutzkorb verwendet wird. Als Vergußmassen für die Lampe kommen Akrylsäure mit Härtemitteln oder Polyesterharze in Betracht. Diese Stoffe bleiben Lis mindestens 8o bis i2o° C völlig ungetrübt. Als Lampen sollen dabei Leuchtstofflampen, Ouecksilberdampflampen od. ä. Entladungslampen verwendet werden.The invention relates to a firedamp and explosion-proof Luminaire with a helical discharge lamp, especially for mines, and consists in that the discharge lamp in a transparent plastic body, preferably made of synthetic resin. This completely secures the lamp against breakage, without using a special protective cage. As a casting compound for the lamp Acrylic acid with hardeners or polyester resins come into consideration. These substances Lis remain at least 8o to 12o ° C completely undisturbed. The lamps should be fluorescent lamps, Mercury vapor lamps or similar discharge lamps are used.
Die Leuchte kann auch in Verbindung mit einem in die Leuchte eingebauten, völlig vergossenen Transformator betrieben werden, dessen Primärseite auf ein Netz von niedriger Spannung, beispielsweise 6o Volt, geschaltet ist. Zu diesem Zweck ist die Leuchte in einen Anschlußraum, in den völlig vergossenen Transformatorraum und in den ebenfalls vollständig vergossenen Lampenraum unterteilt. Zweckmäßig kann auch der Transformator und/oder die Vorschaltdrossel in den die Lampe enthaltenden Kunststoffkörper mit eingegossen sein.The luminaire can also be used in conjunction with a built-in fully encapsulated transformer are operated, the primary side of which is connected to a network of low voltage, for example 6o volts, is switched. To this end is the luminaire in a connection room, in the completely encapsulated transformer room and subdivided into the lamp compartment, which is also completely encapsulated. Appropriate can also the transformer and / or the series choke in the one containing the lamp Plastic body to be cast in.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The drawing shows an embodiment of the invention.
Die kegelwendelförmig gestaltete Quecksilberdampflampe i ist mit einem glasklaren, härtbaren Kunstharz, z. B. Polyesterharz, in Form einer Halbkugel 2 mit einem Halteflansch 3 umgossen. Die Halbkugel ist am Leuchtengehäuse a. durch den Ring 5 und durch Schraubbolzen 6 unter Zwischenlage einer Gummidichtung 7 gehalten. Die Lampenelektroden sind über Steckverbindungen 8 mit einem Kleintransformator 9 verbunden, der mit den Steckverbindungen ebenfalls in einen Isolierkörper io eingegossen ist. Dieser den Transformator enthaltende Körper io kann auch zusammen mit dem Körper 2 aus einem Stück bestehen. Die Primärseite d°s Transformators ist ebenfalls durch Steckverbindungen i i mit der Anschlußdose 12 verbunden, an deren Klemmen 13 die beiden Adern i4 des Kabels 15 angeschlossen sind.The cone-shaped mercury vapor lamp i is with a clear, hardenable synthetic resin, e.g. B. polyester resin, in the form of a hemisphere 2 encapsulated with a retaining flange 3. The hemisphere is on the luminaire housing a. by the ring 5 and held by screw bolts 6 with a rubber seal 7 in between. The lamp electrodes are connected to a small transformer via plug connections 8 9 connected, which is also cast into an insulating body io with the plug connections is. This body containing the transformer can also be used together with the body 2 consist of one piece. The primary side of the transformer is also through Plug connections i i connected to the junction box 12, at whose terminals 13 the both wires i4 of the cable 15 are connected.
Soll die Leuchte an eine Netzspannung von 22o Volt bei Verwendung einer Leuchtstofflampe angeschlossen werden, so kann der Transformator durch eine Drossel ersetzt und eine der bekannten Zündvorrichtungen eingebaut werden.Should the lamp be connected to a mains voltage of 22o volts when in use connected to a fluorescent lamp, the transformer can be replaced by a Choke replaced and one of the known ignition devices installed.
