Description

  

   <Desc/Clms Page number 1> 
 



    Spar- bzw. Notbeleuchtungskörper.   



   Glühlampen mit eingebauten Transformatoren sind an sich bekannt. 



   Gegenstand der Erfindung sind elektrische   Beleuchtungskörper   in deren Sockel man einen entsprechend geformten und isolierten Kleintransformator und ein   Niedervoltlämpchen   einbauen kann. 



  Der Transformator ist mit einem Spezialschalter des   Beleuchtungskörpers   verbunden. Der Primärstrom geht über dem Spezialschalter sowohl zur normalen Glühlampe des   Beleuehtungskörpers,   als auch zum parallel angeschlossenem Transformator. 



   Der Sekundärstrom des Transformators geht ebenfalls über dem Spezialsehalter dem im   Beleuch-   tungskörper entsprechend eingebautem   Niedervoltlämpehen.   



   Schaltung 1 : Die normale Glühlampe im Beleuchtungskörper brennt. Ausserdem ist der Transformator unter Primärspannung. Die Sekundärseite ist noch ausgeschaltet. 



     Schaltung   2 : Die normale Glühlampe erlis. ht, da die Stromzufuhr ausgeschaltet ist. Dagegen bleibt der Transformator weiter unter Spannung, wobei die   Sekundärseite   eingeschaltet wurde. Das   Niedervoltlämpchen brennt.   



   Schaltung 3 : Die Stromzufuhr zur Primärseite wird abgeschaltet, das   Niedervoltlämpchen   erliseht, der ganze Beleuchtungskörper ist stromlos. 



   Der Einbau des kleinen Transformators kann in allen Arten von elektrischen   Beleuchtungskörpern     form entsprechend erfolgen.

    Economy or emergency lighting.



   Incandescent lamps with built-in transformers are known per se.



   The invention relates to electrical lighting fixtures in the base of which a correspondingly shaped and insulated small transformer and a low-voltage lamp can be installed.



  The transformer is connected to a special switch on the lighting fixture. The primary current goes through the special switch both to the normal light bulb of the lighting body and to the transformer connected in parallel.



   The secondary current of the transformer also goes via the special switch to the low-voltage lamp built into the lighting unit.



   Circuit 1: The normal incandescent lamp in the lighting fixture burns. In addition, the transformer is under primary voltage. The secondary side is still switched off.



     Circuit 2: The normal light bulb is lost. ht because the power is off. On the other hand, the transformer remains live, with the secondary side being switched on. The low-voltage lamp burns.



   Circuit 3: The power supply to the primary side is switched off, the low-voltage lamp goes out, the entire lighting fixture is de-energized.



   The installation of the small transformer can be done in all types of electrical lighting fixtures.

PATENT-ANSPRUCH : EMI1.1 Transformator, dadurch gekennzeichnet, dass durch Betätigung eines geeigneten Schalters die Sekundärseite des Niedervolt-Transformators an ein gleichfalls in dem Beleuchtungskörper eingebautes Niedervoltlämpchen gelegt werden kann. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: EMI1.1 Transformer, characterized in that, by actuating a suitable switch, the secondary side of the low-voltage transformer can be connected to a low-voltage lamp that is also built into the lighting fixture. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
