Zur Beleuchtung der Betriebsanzeige elektrischer Geräte, wie Heißwassergeräte, Waschmaschinen, Heizlüfter, Elektrogeräte als auch Lichtschalter und Drucktaster werden als Lichtquellen überwiegend Glimmlampen aber auch Leuchtdioden und Glühlampen eingesetzt. Üblicherweise werden diese Lichtquellen in gesockelter Form verwendet. Dabei können die mit einem Hohlkörper, der die Leuchtquelle umschließt, versehenen Lichtquellen einen daran angeformten Sockel aufweisen, der in das jeweilige Gerät eingesetzt wird, oder es ist ein zusätzlicher Stecksockel erforderlich, in welchen die Lichtquellen eingesetzt werden. Im letzteren Fall werden die aus dem Hohlkörper herausgeführten Anschlußdrähte an ihren Enden umgebogen und dienen als Anschlußkontakte, die beim Einsetzen in den Stecksockel mit den dort befindlichen Gegenkontakten die Stromverbindung sicherstellen.To illuminate the operating display of electrical devices, such as hot water devices, washing machines, fan heaters, electrical devices as well as light switches and push buttons are considered Light sources predominantly glow lamps but also light emitting diodes and incandescent lamps used. Usually these are Socketed light sources used. You can with a hollow body that encloses the light source, provided light sources have a base molded onto them, which is inserted into the respective device, or it an additional plug-in base is required, in which the light sources are used. In the latter case the lead wires led out of the hollow body bent at their ends and serve as connection contacts, those when inserted into the socket with the ones located there Ensure the power connection to mating contacts.
Generell ist zu beachten, daß der Einsatz derartiger Lichtquellen am normalen Versorgungsnetz nur mit einem Vorwiderstand erfolgt, um den Strom zu begrenzen und unzulässige Stromüberschreitungen auszuschließen. Dabei ist jeder Vorwiderstand auf die jeweilige Leistungstype der Lichtquelle abgestimmt. Dies führt dazu, daß beim Auswechseln einer Lichtquelle gegen eine Lichtquelle mit anderen elektrischen Parametern auch der betreffende Vorwiderstand geändert werden muß. Anderenfalls könnte es zu Funktionsstörungen kommen.In general, it should be noted that the use of such light sources on the normal supply network only with a series resistor done to limit the current and impermissible Exclude excess currents. Every series resistor is there to the respective power type of the light source Voted. This means that when replacing one Light source against a light source with other electrical The relevant series resistor can also be changed got to. Otherwise malfunctions could occur.
Insbesondere für Glimmlampen gilt, daß ungesockelte Glimmlampen im allgemeinen mit angepaßten Vorwiderständen angeboten werden. Allerdings ist hierbei die Montage sowie das Auswechseln der Glimmlampe im Falle einer Störung sehr aufwendig.For glow lamps, in particular, unsocked glow lamps apply generally offered with adapted series resistors become. However, here is the assembly as well Replace the glow lamp in the event of a malfunction complex.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung eine Lichtquelle der eingangs genannten Art zu schaffen, welche die vorstehend aufgezeigten Nachteile vermeidet, eine einfache Handhabung gewährleistet und einfach und kostengünstig herstellbar ist. Darüberhinaus soll auf geringe Baugröße geachtet werden, damit die Lichtquelle auch in solchen Geräten Anwendung finden kann, wo es auf platzsparenden Einbau ankommt.Based on this state of the art, it is the task of Invention to a light source of the type mentioned create, which avoids the disadvantages indicated above, easy handling guaranteed and simple and is inexpensive to manufacture. In addition, is said to small size are taken into account so that the light source can also be used in such devices where it is on space-saving installation arrives.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Danach ist vorgesehen, daß der zum Betrieb erforderliche Vorwiderstand in die die Lichtquelle bildende Baueinheit integriert ist, indem der Vorwiderstand unmittelbar an einen der aus dem Hohlkörper herausgeführten Anschlußdrähte angeschlossen ist und die Verbindung mit dem zugeordneten Gegenkontakt im Stecksockel bildet. Auf diese Weise ist sichergestellt, daß jede Lichtquelle mit dem richtigen Vorwiderstand versehen ist und überdies sofort einsatzbereit ist.This object is achieved by the characterizing Features of claim 1 solved.

This ensures that provide each light source with the correct series resistor is and is also immediately ready for use.
Entsprechend der Erfindung ist der aus Glas gebildete Hohlkörper auf seiner Unterseite mit einer Schutzkappe versehen, welche seine Unterseite sowie den hieran anschließenden Vorwiderstand aufnimmt. Ferner sind hierbei der aus dem Glashohlkörper herausgeführte andere Anschlußdraht sowie das freie Ende des Vorwiderstands, welche beide als Anschlußkontakte dienen, ebenfalls gegeneinander isoliert durch die Schutzkappe nach außen geführt, wo sie in gleicher Weise rückgebogen sind und hierdurch einerseits die gewünschte Kontaktfläche als Anschlußkontakt bilden und andererseits die Schutzkappe daran hindern, von dem Hohlkörper abzugleiten.According to the invention is the hollow body made of glass on its underside with a protective cap covering its underside as well as the series resistor connected to it. Furthermore, here are those led out of the hollow glass body other connecting wire as well as the free end of the Series resistor, both of which serve as connection contacts, also isolated from each other by the protective cap led outside where they are bent back in the same way and thereby on the one hand the desired contact area as Form connection contact and on the other hand the protective cap prevent it from sliding off the hollow body.
In vorteilhafter Ausgestaltung der Erfindung ist der Vorwiderstand zylindrisch ausgebildet mit jeweils an den Stirnseiten anschließenden Anschlußdrähten. Ein solcher Vorwiderstand ist als handelsüblicher Kohleschicht- bzw.
