Description

Beleuchtungsanlage mit elektrischen, ein schwer verdampfbares Metall enthaltenden Entladungslampen, mit denen Variotoren in Reihe geschaltet sind Die Erfindung bezieht .sich auf eine Beleuchtungsanlage, in der .eine oder mehrere elektrische Entladungslampen mit schwer verdampfbarem Metall, dessen Dampf sich an der Lichtemission beteiligt, vorgesehen sind. Unter schwer verdampfbare Metalle sind hier die zum Erzeugen einer Dampfatmosphäre in Entladungsröhren benutzten Metalle, z. B. Natrium, zu verstehen, deren Dampfdruck bei einer Temperatur von zoo° C nur einen Bruchteil :eines Millimeters beträgt. Um den Strom in diesen Röhren konstant zu halten, ist es bekannt, in Reihe mit den Entladungslampen einen Variator zu schalten. Bekanntlich besteht solch ein Variator oft aus einem in einer Gasatmosphäre angeordneten Widerstandsdraht mit einem großen positiven Temperaturkoeffizienten des elektrischen Widerstandes.Lighting system with electrical, a metal that is difficult to vaporize containing discharge lamps with which variotors are connected in series The invention relates to a lighting system in which one or more electrical Discharge lamps with metal that is difficult to vaporize, the vapor of which is involved in the emission of light involved, are provided. Among the metals that are difficult to vaporize are those for Generating a vapor atmosphere in discharge tubes used metals, e.g. B. Sodium, to understand whose vapor pressure at a temperature of zoo ° C is only a fraction : is one millimeter. In order to keep the current in these tubes constant, is it is known to connect a variator in series with the discharge lamps. As is well known Such a variator often consists of a resistance wire arranged in a gas atmosphere with a large positive temperature coefficient of electrical resistance.

Es hat sich gezeigt, daß die Eigenschaften dieser Entladungslampen durch die Temperaturschwankungen der Umgebung beeinflußt werden. Wenn die Stromstärke durch die Entladungslampen derart eingestellt ist, daß sie bei einer bestimmten Umgebungstemperatur sehr günstig brennen, z. B. mit der größten Nutzwirkung, so zeigt -es sich, daß sich die Lage bei Änderung der Uxngebungstemperatur viel ungünstiger gestalten kann. Wenn z. B. diese Temperatur sinkt, so kann die Wärmeabgabe der Entladungslampen wesentlich größer werden, so daß sie eine niedrigere Temperatur und der in den Röhren vorhandene Metalldampf einen kleineren Druck erhält, was eine Verringerung der Nutzwirkung herbeiführen kann. Ebenso kann eine Steigerung der Umgebungstemperatur einen -erhöhten Dampfdruck bewirken und infolgedessen ebenfalls die Nutzwirkung beeinträchtigen.It has been shown that the properties of these discharge lamps be influenced by the temperature fluctuations of the environment. When the amperage is set by the discharge lamps so that they are at a certain Burn at ambient temperature very favorably, e.g. B. with the greatest usefulness, like this It turns out that the situation is much more unfavorable when the ambient temperature changes can shape. If z. B. if this temperature drops, the heat output of the discharge lamps are much larger, so they have a lower temperature and that in the tubes existing metal vapor is given a lower pressure, which reduces the useful effect can bring about. An increase in the ambient temperature can also increase the temperature Cause vapor pressure and consequently also impair the usefulness.

Gemäß der Erfindung wird dies dadurch verbessert, da.ß der Variator den gleichen Temperaturschwankungen wie dieEntladungslampen ausgesetzt wird. Bei niedrigerer Umgebungstemperatur regelt der Variator nämlich den Strom auf eine größere Stärke .als bei höherer Temperatur. Dieser stärkere Strom verursacht in den Entladungslampen eine größere Wärmeentwicklung, die dem Einfluß der gesteigerten Wärmeabgabe, die durch eine Abnahme der Umgebungstemperaturherbeigeführtwwird, entgegenwirkt undgegebenenfalls ganz ausgleicht.According to the invention this is improved by the fact that the variator is exposed to the same temperature fluctuations as the discharge lamps. at The variator regulates the current to a higher one when the ambient temperature is lower Strength. Than at higher temperature. This stronger current causes in the discharge lamps one greater heat development, which is influenced by the increased heat dissipation caused by a decrease in the ambient temperature is caused, counteracted and, if necessary completely compensates.

Falls die Anlage zur Beleuchtung von Wegen, Plätzen o. dgl. verw endet wird und wennsie z:». eine Anzahl Natriumdampfentladungslampen, die in der Regel mit einer wärmeisolierenden Hülle (z. B. einer doppelwandigen Hülle) versehen sind, und außer demeinen oder mehrere z. B. aus einem meiner Gasatmosphäre angeordneten Eisendrahtwiderstand bestehende Variatoren enthält, so werden diese Variatoren ebenso wie die Entladungslampen, mit denen sie in Reihe geschaltet sind, im Freien angeordnet. Es hat sich erwiesen, daß die Entladungslampen dieser Anlage viel weniger von der Außentemperaturabhängig sind als Anlagen, bei, denen die Variatoren z. B. in einem Transformatorhäuschen untergebracht sind.If the system is used to illuminate paths, squares or the like will and if you z: ». a number of sodium vapor discharge lamps that usually are provided with a heat-insulating cover (e.g. a double-walled cover), and besides one or more z. B. arranged from one of my gas atmosphere If iron wire resistance contains existing variators, so will these variators as well like the discharge lamps with which they are connected in series, arranged outdoors. It has been shown that the discharge lamps in this system are much less affected by the Outside temperature-dependent are as systems in which the variators z. B. in one Transformer houses are housed.
