Glühwendel für eine Glühlampe und GlühlampeFilament for an incandescent lamp and incandescent lamp
Die Erfindung betrifft eine Glühwendel für eine Glühlampe gemäß des Oberbegriffs des Patentanspruchs 1 und eine Glühlampe mit einer derartigen Glühwendel.The invention relates to a filament for an incandescent lamp according to the preamble of claim 1 and an incandescent lamp with such a filament.
I. Stand der TechnikI. State of the art
Eine derartige Glühwendel ist beispielsweise in der europäischen Offenlegungs- schrift EP 1 255 279 A2 offenbart. Diese Schrift beschreibt eine Halogenglühlampe, deren Abmessung quer zu ihrer Längserstreckung maximal nur 6 mm beträgt. Diese Lampe ist zum Einsatz in einer Taschenleuchte vorgesehen. Die Glühwendel dieser Halogenglühlampe besitzt zwei Wendelabgänge, die jeweils mit einem Stromzuführungsdraht verschweißt sind.Such an incandescent filament is disclosed, for example, in European laid-open publication EP 1 255 279 A2. This document describes a halogen incandescent lamp, the dimension of which is a maximum of only 6 mm across its longitudinal extent. This lamp is intended for use in a flashlight. The incandescent filament of this halogen incandescent lamp has two filament outlets, each of which is welded to a power supply wire.
II. Darstellung der Erfindung Es ist die Aufgabe der Erfindung, eine Glühwendel für eine Glühlampe bcreitzustel- len, die sich auf möglichst einfache Weise innerhalb eines axialsymmctrischen Lampengefäßes parallel versetzt zur Lampengefäßachse fixieren lässt. Außerdem ist es die Aufgabe der Erfindung, eine Glühlampe mit einer entsprechenden Glühwendel bereitzustellen.II. Representation of the Invention It is the object of the invention to provide an incandescent filament for an incandescent lamp which can be fixed in the simplest possible way within an axially symmetrical lamp vessel, offset parallel to the lamp vessel axis. It is also the object of the invention to provide an incandescent lamp with a corresponding incandescent filament.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in den abhängigen Patentansprüchen beschrieben.This object is achieved by the features of claim 1. Particularly advantageous embodiments of the invention are described in the dependent claims.
Die beiden Wendelabgänge der erfindungsgemäßen Glühwendel weisen jeweils einen abgewinkelten Schenkel auf, die in einer gemeinsamen, parallel versetzt zur Wickelachse der Glühwendel verlaufenden Ebene angeordnet sind. Dadurch kann in einem axialsymmetrischen Lampengefäß, das an einem Ende abgedichtet ist, ohne zusätzliche Maßnahmen eine axiale Ausrichtung der Glühwendel, parallel versetzt zur Symmetrieachse des Lampengefäßes realisiert werden. Zu diesem Zweck genügt es, dass die abgewinkelten Wendelabgänge jeweils mit einem in dem abgedichteten Ende des Lampengefäßes eingebetteten Stromzuführungsteil verbunden sind. Insbesondere kann daher auf ein Gestell zur Halterung der Glühwendel in dem Lampenge- faß verzichtet werden.The two filament outlets of the filament according to the invention each have an angled leg, which are arranged in a common plane running parallel to the winding axis of the filament. As a result, an axial alignment of the incandescent filament can be offset in parallel in an axially symmetrical lamp vessel, which is sealed at one end, without additional measures for the axis of symmetry of the lamp vessel. For this purpose, it is sufficient that the angled filament outlets are each connected to a power supply part embedded in the sealed end of the lamp vessel. In particular, a frame for holding the incandescent filament in the lamp vessel can therefore be dispensed with.
Vorzugsweise sind die beiden Wendelabgänge der erfindungsgemäßen Glühwendel jeweils L-förmig ausgebildet. Das heißt, jeder Wendelabgang ist nur einmal und zwar rechtwinklig abgewinkelt. Ein erster L-Schenkel jedes Wendelabgangs ist mit dem für die Lichtemission verantwortlichen Bereich der Glühwendel verbunden, während ein zweiter L-Schenkel davon im rechten Winkel abgewinkelt ist, so dass diese zweiten L-Schenkel der beiden Wendelabgänge in einer gemeinsamen, parallel versetzt zur Wickelachse der Glühwendel verlaufenden Ebene angeordnet sind.Preferably, the two filament outlets of the filament according to the invention are each L-shaped. This means that each spiral outlet is only angled once and at right angles. A first L-leg of each filament exit is connected to the area of the incandescent filament responsible for the light emission, while a second L-leg is angled at a right angle therefrom, so that these second L-legs of the two filament exits in a common, offset parallel to the winding axis the filament extending plane are arranged.
Die erfindungsgemäße Glühwendel eignet sich besonders gut zum Einsatz in Glühlampen, vorzugsweise Halogenglühlampen, die zum Zweck einer gerichteten Licht- abstrahlung ein mit einer lichtreflektierenden Beschichtung versehenes, axialsymmetrisches Lampengefäß und eine axial ausgerichtete, parallel versetzt zur Lampen- gefaßachse angeordnete Glühwendel aufweisen.The incandescent filament according to the invention is particularly well suited for use in incandescent lamps, preferably halogen incandescent lamps, which, for the purpose of directed light emission, have an axially symmetrical lamp vessel provided with a light-reflecting coating and an axially aligned incandescent filament which is arranged parallel to the lamp vessel axis.
Die erfindungsgemäße Glühlampe weist ein axialsymmetrisches, lichtdurchlässiges Lampengefäß, das an einem Ende abgedichtet und mit Stromdurchführungen verse- hen ist, sowie eine axial in dem Lampengefäß ausgerichtete, parallel versetzt zur Lampenge fäßachse angeordnete Glühwendel auf, wobei die Glühwendel zwei Wendelabgänge mit jeweils einem abgewinkelten Schenkel, die in einer gemeinsamen, parallel versetzt zur Wickelachse der Glühwendel verlaufenden Ebene angeordnet sind, besitzt, und wobei die abgewinkelten Schenkel jeweils mit einem in dem abge- dichteten Ende des Lampengefäßes eingebetteten Stromzuführungsteil verbunden sind. Dadurch wird ohne zusätzliche Maßnahmen eine zuverlässige, außermittige Halterung der Glühwendel in dem Lampengefäß gewährleistet. Insbesondere ist kein aufwändiger Gestellaufbau zur Wendelhalterung nötig. Bei den in dem abgedichteten Ende des Lampengefäßes eingebetteten Stromzufuhrungsteilen, mit denen die abgewinkelten Schenkel verbunden sind, handelt es sich vorteilhafter Weise jeweils um eine Metallfolie, insbesondere eine Molybdänfolie, die einerseits als Stromzuführung für die Glühwendel dienen und sich andererseits zur Abdichtung des Lampengefäßes eignen, da sie gasdicht in dem abgedichteten Ende des Lampengefäßes eingeschmolzen werden können.The incandescent lamp according to the invention has an axially symmetrical, translucent lamp vessel which is sealed at one end and provided with current feedthroughs, and an incandescent filament which is axially aligned in the lamp vessel and is arranged offset parallel to the lamp vessel axis, the incandescent filament having two angled legs , which are arranged in a common plane parallel to the winding axis of the incandescent filament, and wherein the angled legs are each connected to a power supply part embedded in the sealed end of the lamp vessel. This ensures reliable, off-center mounting of the filament in the lamp vessel without additional measures. In particular, no complex frame structure for the helix holder is necessary. The power supply parts embedded in the sealed end of the lamp vessel, with which the angled legs are connected, are each advantageously a metal foil, in particular a molybdenum foil, which serve on the one hand as a power supply for the incandescent filament and on the other hand are suitable for sealing the lamp vessel, since they can be melted gas-tight in the sealed end of the lamp vessel.
Das Lampengefäß der erfindungsgemäßen Glühwendel ist vorzugsweise mit einer lichtreflektierenden Beschichtung versehen, die sich über einen Teil des Umfangs des Lampengefäßes erstreckt, und die Glühwendel ist vorzugsweise in Richtung der lichtreflektierenden Beschichtung parallel versetzt zur Lampengefäßachse angeordnet, um eine gerichtete Lichtabstrahlung in einen bevorzugten Raumwinkel zu erreichen.The lamp vessel of the incandescent filament according to the invention is preferably provided with a light-reflecting coating which extends over part of the circumference of the lamp vessel, and the incandescent filament is preferably arranged offset parallel to the lamp vessel axis in the direction of the light-reflecting coating in order to achieve directional light radiation in a preferred solid angle ,

Die Beschichtung 104 erstreckt sich über 50 Prozent des Umfangs des kreiszylindrischen Gefäßabschnitts 102 und reicht bis zum Pumpstängelansatz 103. Mit anderen Worten ausgedrückt, die Beschichtung 104 bedeckt eine Halbschale des zy- lindrischen Lampengefäßabschnitts 102 und ist bis zum Pumpstängelansatz 103 fortgesetzt. Die Beschichtung 104 besteht aus einer ersten, unmittelbar auf der Oberfläche des Lampengefäßes aufgebrachten lichtreflektierenden Silberschicht, einer zweiten, darauf aufgebrachten lichtundurchlässigen Chromschicht und einer dritten, auf der Chromschicht angeordneten Si02-Schutzschicht. Die Glühwendel HO ist axial ausgerichtet und parallel versetzt gegenüber der Zylinderachse A-A des kreiszylindrischen Gefäßabschnitts 102 angeordnet. Der Außendurchmesser des Lampengefäßes 100 beträgt 9,5 mm und seine Wandstärke 1 mm. Die Achse 1 104 der Glühwendel 1 10, die identisch mit ihrer Wickelachse ist, ist um 2 mm gegenüber der Zylinderachse A-A in Richtung der Beschichtung 104 parallel verschoben. Die beiden abge- winkelten Schenkel 1 1021 bzw. 1 1031 der Wendelabgänge der Glühwendel 1 10 sind mit der Molybdänfolie 123 bzw. 124 verschweißt. Außerdem sind die beiden abge- winkelten Schenkel 11021 und 11031 in einer gemeinsamen Ebene, d.h. in der Ebene der Molybdänfolien 123, 124, die auch die Zylinderachse A-A enthält, angeordnet und verlaufen parallel zueinander. Die Achse, das heißt, die Wickelachse 1 104 der Glühwendel 110 ist außerhalb der vorgenannten Ebene, um 2 mm parallel versetzt zur Zylinderachse A-A angeordnet. In der Orientierung der Figur 3 verläuft die Wickelachse 1104 der Glühwendel 1 10 ungefähr 2 mm unterhalb der durch die abgewinkelten Schenkel 11021 und 1 1031 definierten Ebene. Die Quetschdichtung 101 ist in einem G4-Sockel (nicht abgebildet) angeordnet.The exemplary embodiment of the incandescent lamp shown in FIGS. 3 and 4 is a halogen incandescent lamp with an electrical power consumption of approximately 20 watts. This lamp has a lamp vessel 100 made of quartz glass, which is sealed gas-tight at one end by means of a pinch seal 101. The lamp vessel 100 also has a circular cylindrical vessel section 102 and a pump stem attachment 103 arranged diametrically to the pinch seal 101. A filament 110 according to FIG. 1 is arranged inside the lamp vessel 100. The angled legs 1 1021, 1 1031 of their two spiral outlets are each connected to a gas-tight molybdenum foil 123, 124 embedded in the pinch seal 101. The molybdenum foils 123, 124 are each connected to a contact pin 125, 126 of the halogen incandescent lamp protruding from the pinch seal 101. The circular cylindrical vessel section 102 is provided with a light-reflecting coating 104 on its outer surface. The coating 104 extends over 50 percent of the circumference of the circular cylindrical vessel section 102 and extends as far as the pump stem attachment 103. In other words, the coating 104 covers a half-shell of the cylindrical lamp vessel portion 102 and is continued up to the pump stem attachment 103. The coating 104 consists of a first light-reflecting silver layer applied directly to the surface of the lamp vessel, a second opaque chrome layer applied thereon and a third SiO 2 protective layer arranged on the chrome layer. The incandescent filament HO is aligned axially and offset parallel to the cylinder axis AA of the circular-cylindrical vessel section 102. The outer diameter of the lamp vessel 100 is 9.5 mm and its wall thickness is 1 mm. The axis 1 104 of the incandescent filament 1 10, which is identical to its winding axis, is displaced parallel to the cylinder axis AA by 2 mm in the direction of the coating 104. The two angled legs 1 1021 and 1 1031 of the filament branches of the incandescent filament 1 10 are welded to the molybdenum foil 123 and 124, respectively. In addition, the two angled legs 11021 and 11031 are arranged in a common plane, ie in the plane of the molybdenum foils 123, 124, which also contains the cylinder axis AA, and run parallel to one another. The axis, that is, the winding axis 1 104 of the incandescent filament 110 is arranged outside the aforementioned plane, offset by 2 mm parallel to the cylinder axis AA. 3, the winding axis 1104 of the incandescent filament 110 extends approximately 2 mm below the plane defined by the angled legs 11021 and 11031. The pinch seal 101 is arranged in a G4 base (not shown).
Die Erfindung beschränkt sich nicht auf die oben näher erläuterten Ausführungsbei- spiele der Erfindung. Beispielsweise kann anstelle der oben beschriebenen Beschichtung 104 auch ein sogenannter Kaltlichtspiegel verwendet werden, der für Infrarotstrahlung transparent ist und elektromagnetische Strahlung aus dem sichtbaren Spektralbereich reflektiert. Die beiden abgewinkelten, in einer gemeinsamen Ebene angeordneten L-Schenkel 1 1021 , 1 1031 müssen nicht unbedingt parallel zueinander verlaufen, sondern ihr Abstand kann beispielsweise in Richtung der Molybdänfolien 123, 124 zunehmen. Ferner kann die Erfindung auch auf Glühlampen und Glühwendeln anderer Leistungsstufen als 20 Watt angewendet werden. The invention is not limited to the exemplary embodiments of the invention explained in more detail above. For example, instead of the coating 104 described above, a so-called cold light mirror can also be used, which is transparent to infrared radiation and reflects electromagnetic radiation from the visible spectral range. The two angled L-legs 1 1021, 1 1031 arranged in a common plane do not necessarily have to run parallel to one another, but their distance can increase, for example, in the direction of the molybdenum foils 123, 124. Furthermore, the invention can also be applied to incandescent lamps and filaments other than 20 watts.
