Die Erfindung betrifft eine Glühlampe, insbesondere eine Niedervoltleuchte.The invention relates to an incandescent lamp, in particular a low-voltage lamp.
&iacgr;&ogr; Ausgangssituation &iacgr;&ogr; Initial situation
Glühlampen nutzen die Eigenschaft, daß ein hocherhitzter Faden zum Glühen angeregt wird. Dies kann im Normalfall mit einem elektrischen Strom geschehen, der der Leuchte direkt zugeführt wird. Der Glühfadenstrom ist damit direkt von der Netzspannung abhängig, Spannungsspitzen können den Faden zerstören. Bei Niedervoltleuchten wird über eine Anpaßschaltung die Netzspannung auf die gewünschte niedrigere Spannung reduziert. Dadurch kann der Glühfaden stabiler gestaltet werden, sein Innenwiderstand ist geringer und die benötigte Leistung reduziert sich.Incandescent lamps use the property that a highly heated filament is stimulated to glow. This can normally be done with an electric current that is fed directly to the lamp. The filament current is therefore directly dependent on the mains voltage, and voltage peaks can destroy the filament. In low-voltage lamps, the mains voltage is reduced to the desired lower voltage using an adapter circuit. This makes the filament more stable, its internal resistance is lower and the power required is reduced.
Der erfmdung liegt die Aufgabe zugrunde, eine Glühlampe der eingangs genannten Art zu schaffen, bei der Spannungsspitzen wie bei netzspannungsbetriebenen Lampen nur reduziert auftreten können und mit welcher eine Anpaßschaltung wie bei Niederspannungslampen eingespart werden kann. Erfindungsgemäß wird die gestellte Aufgabe durch die im Kennzeichen des Anspruchs 1 aufgegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen sind in den Ansprüchen 2 bis 5 angegeben.The invention is based on the object of creating an incandescent lamp of the type mentioned at the beginning, in which voltage peaks can only occur to a reduced extent as with mains voltage operated lamps and with which an adaptation circuit as with low voltage lamps can be saved. According to the invention, the stated object is achieved by the features specified in the characterizing part of claim 1. Advantageous further developments are specified in claims 2 to 5.
Kurz gesagt besteht die Erfindung darin, eine Glühlampe, insbesondere eine Niedervoltlampe, zur indirekten Speisung ihres Niedervoltglühfadens aus dem Versorgungsnetz über einen Heizwiderstand mit angegliedertem Seebeckelement/Peltierlement zu betreiben.In short, the invention consists in operating an incandescent lamp, in particular a low-voltage lamp, for indirectly feeding its low-voltage filament from the supply network via a heating resistor with an attached Seebeck element/Peltier element.
Die Netzspannung in Form von Gleich- oder Wechselspannung versorgt einen Heizwiderstand. Dieser erhitzt durch seine Wärme ein Seebeck/Peltierelement. Durch den Wärmefluß über dieses Element zum Kühlblech und zur Außenluft erzeugt das Element eine elektrische Spannung, die dem Glühfaden zugeführt wird und durch den Laststrom diesen zum Glühen und damit zum Leuchten bringt.The mains voltage in the form of direct or alternating voltage supplies a heating resistor. This heats a Seebeck/Peltier element. The heat flow through this element to the cooling plate and the outside air causes the element to generate an electrical voltage that is fed to the filament and, thanks to the load current, causes it to glow and thus light up.
Im folgenden wird die Erfindung anhand von Fig. 1 und 2 der Zeichnung, welche zwei Ausfuhrungsbeispiele zeigen, noch näher erläutert.In the following, the invention is explained in more detail with reference to Fig. 1 and 2 of the drawing, which show two exemplary embodiments.
Fig. 1 zeigt das elektrische Schaltbild der Neuentwicklung.Fig. 1 shows the electrical circuit diagram of the new development.
An die Anschlußklemmen 9 wird die Netzspannung 1 angelegt. DieThe mains voltage 1 is applied to the connection terminals 9. The
&iacgr;&ogr; Netzspannung 1 treibt einen Strom durch den teilweise wärmeisolierten Heizwiderstand 2. An der nichtisolierten Seite ist ein Seebeckelement/Peltierelement 3 angeordnet. Die Wärme des Heizwiderstandes 2 fließt durch dieses Element 3 und erzeugt dort eine elektrische Spannung, der Glühfaden 7 ist der Lastwiderstand für diese Spannung. Der erzeugte Laststrom bringt den Glühfaden 7 zum Leuchten.Mains voltage 1 drives a current through the partially heat-insulated heating resistor 2. A Seebeck element/Peltier element 3 is arranged on the non-insulated side. The heat from the heating resistor 2 flows through this element 3 and generates an electrical voltage there, the filament 7 is the load resistance for this voltage. The load current generated causes the filament 7 to glow.
Das Kühlblech 5 fuhrt die Wärme vom
Seebeckelement/Peltierelement 3 ab und erhält damit die energieerzeugende Wärmedifferenz an diesem Element 3 aufrecht.The cooling plate 5 conducts the heat from the
Seebeck element/Peltier element 3 and thus maintains the energy-generating heat difference at this element 3.
Fig. 2 zeigt einen möglichen Aufbau der Leuchte. Aus dem nicht dargestellten Glaskörper ragen die Anschlußklemmen 9 heraus. Sie fuhren zu dem teilisolierten Heizwiderstand 2. An den Widerstand anliegend das Seebeckelement 3, dessen Ausgangsspannung durch den Laststrom 8 den Glühfaden 7 zum Glühen bringt. Das Kühlblech 5 leitet die Wärme vom Seebeckelement 3 an die Außenluft 6 ab.Fig. 2 shows a possible design of the lamp. The connecting terminals 9 protrude from the glass body (not shown). They lead to the partially insulated heating resistor 2. The Seebeck element 3 is connected to the resistor, the output voltage of which causes the filament 7 to glow due to the load current 8. The cooling plate 5 conducts the heat from the Seebeck element 3 to the outside air 6.
