Description

Elektrische Glühlampe in Form einer Kerzenflamme Die Erfindung bezieht sich auf diejenigen elektrischen Glühlampen, welche im großen und ganzen die Form seiner Kerzenfbnime haben. Solche Lampen kannten bisher in brauchbarer Form nicht mit einem Kolben aus durchscheinendem, sogenanntem Opalglas hergestellt werden, obwohl bei diesen. Glühlampen ein diffuses Licht, welches der Kerzenflamme ähnlich- ist, erwünscht wäre, da sie bisher nur als Vakuumlampen hergestellt werden konnten und deshalb zur raschen Schwärzung neigen, was zur Folge hat, daß Lampen mit Opalglaskolben nach kurzer Brennzeit eine schmutziggraue Eäxbung aufweisen. Mit Gas konnten wiederum diese Lampen deshalb nicht ,gefüllt werden, wieil die Kolbenwand durch die Wärmeleitung des Gases viel zu heiß wird.Electric incandescent lamp in the form of a candle flame The invention relates refer to those electric light bulbs which by and large take the form of his candlesticks. Such lamps were previously unknown in a usable form be made with a bulb made of translucent, so-called opal glass, although with these. Incandescent lamps emit diffuse light, which is similar to the flame of a candle. is, would be desirable, since they could previously only be produced as vacuum lamps and therefore tend to blacken quickly, which means that lamps with opal glass bulbs show a dirty gray finish after a short burning time. With gas again these lamps are therefore not filled, as the bulb wall is through the conduction of heat the gas gets too hot.

Die erfindungsgemäße Lampe ist eine in Form einer Kerzenflamme ausgeführte Glühlampe mit einem Kolben aus Opalglas, welche einen wendelföTmigen Glühkörper, eine Gasfüllung aus Krypton unter evtl. Beimengung von geringeren Mengen Argon oder Stickstoff öder beiden Gasen zugleich enthält und einen Gasdruck von mehr. als 200 mm Quecksübersäule hat.The lamp according to the invention is designed in the form of a candle flame Incandescent lamp with a bulb made of opal glass, which has a helical incandescent body, a gas filling made of krypton with possibly the addition of smaller amounts of argon or Contains nitrogen or both gases at the same time and a gas pressure of more. than 200 mm of mercury column.

Die mehr als 20o mm Quecksilbersäule Gasdrucküberschreitende Kryptonfüllung ermöglicht es, seine in Form- einer Kerzenflamme ;geformte gasgehüllte elektrische Glüh-Lampe herzustellen, deren Wand nicht übermäßig warm wird, ohne über die heute üblichen Dimensionen der Kerzenlampe hinauszugehen. Die Gasfüllung und die dadurch erreichte Verringerung der Schwärzung ermöglicht es wiederum, einen Kolben aus Opalglas zu verwenden und auf diese Weise eine Lampe mit rein diffusem Licht herzustellen.The more gas pressure border than 20o mm of mercury krypton filling enables its in form of a candle flame, produce h shaped gasgehüllte electrical Glü lamp, the wall does not become excessively hot, without going beyond the usual today dimensions of the candle lamp. The gas filling and the resulting reduction in blackening make it possible in turn to use a bulb made of opal glass and in this way to produce a lamp with purely diffuse light.

Die erfindungsgemäße, Lampe hat außer den obergenannten Vorteilen noch die bekannten Vorzüge der Kryptonfüllung usw., die erhöhte ökonomie und Lebensdauer sowie das viel weißere Licht. Durch die Erfindung erreicht die Qualität der Lampe diejenige der Normallampen, so daß die handlichere Form mit der guten Qualität vereint wird und eine weitere Verbreitung der bezeichneter Glühlampe @ermöglicht.The lamp according to the invention also has the advantages mentioned above nor the well-known advantages of the krypton filling, etc., the increased economy and service life as well as the much whiter light. The invention achieves the quality of the lamp that of normal lamps, so that the more manageable shape is combined with the good quality and a further distribution of the designated incandescent lamp @ is made possible.

Der Kolben der Lampe kann in an und für sich bekannter Weise aus Opalüberfangglas bestehen.The bulb of the lamp can be made of opal flashed glass in a manner known per se exist.
