Abstract

A gas-discharge vessel for compact lamps consists of an evacuated or gas-filled outer sleeve, which is at least partially transparent, is closed in a sealed manner on all sides and is equipped with at least two electrodes having connections for supplying power from a ballast. In order to achieve an illuminating surface that is as large as possible with a compact construction it is provided that the diameter of the outer sleeve corresponds approximately to the external diameter of the compact lamp and the electrode connections are arranged such that they can be connected directly but detachably to the ballast to form a complete compact lamp.

Description

Kompaktlampen, auch Sparlampen genannt, sind in den letzten Jahren aufgrund ihres geringen Stromverbrauchs von nur etwa einem Fünftel im Vergleich zu herkömmlichen Glühlampen stark gefragt.Compact lamps, also called energy-saving lamps, have been in high demand in recent years due to their low power consumption of only about a fifth compared to conventional incandescent lamps.

Leider besitzen die bisherigen Konstruktionen einige gravierende Nachteile, nämlich eine wesentlich größere Baulänge als Glühlampen und sie benötigen aufwendige elektronische Vorschaltgeräte, um die Lampen zu starten und ihre Stromaufnahme zu begrenzen, was of zu klobigen und plumpen Lösungen führte.Unfortunately, the previous designs have some serious disadvantages, namely a much longer length than incandescent lamps and they require complex electronic ballasts to start the lamps and limit their current consumption, which often leads to bulky and clumsy solutions.

Aufgabe der Erfindung ist eine möglichst große Leuchtfläche bei gedrängtem Aufbau und sparsamen Aufwand zu erzielen.The object of the invention is to achieve the largest possible luminous area with a compact structure and economical effort.

Herkömmliche Kompaktlampen benützen fast ausschließlich dünne Rohre von etwa 10 bis 12 mm Durchmesser, welche als mehrere parallel angeordnete, aber in Serie geschaltete Stäbe verbunden werden.Conventional compact lamps almost exclusively use thin tubes of approximately 10 to 12 mm in diameter, which are connected as several rods arranged in parallel but connected in series.

Fig. 1 bis 2 stellen eine solche bekannte Anordnung dar. Eine bessere Lösung kann man durch eine gewendelte Ausführung der Rohre erreichen, wie sie in Fig. 3 und 4 dargestellt ist. Hier ergeben sich bereits bei gleicher Baugröße größere Rohrlängen und damit höhere Leistungen.1 to 2 represent such a known arrangement. A better solution can be achieved by a coiled design of the tubes, as shown in FIGS. 3 and 4. In this case, longer pipe lengths and thus higher outputs are obtained with the same size.

Fig. 5 und 6 zeigen eine weitere Verbesserung, indem der Innenraum der Wendel so gestaltet ist, daß zumindest Teile des Vorschaltgerätes im Zentrum der Leuchtwendel untergebracht werden können, was entweder eine verkürzte Ausführung der Lampe bei gleicher Leistung, oder eine höhere Leistung bei gleicher Baulänge gestattet.5 and 6 show a further improvement in that the interior of the filament is designed such that at least parts of the ballast can be accommodated in the center of the filament, which is either a shortened version of the lamp with the same power or a higher power with the same overall length allowed.

Allen beschriebenen Ausführungen haftet jedoch der gemeinsame Nachteil an, daß zwischen den Rohren nichtleuchtende Zonen bestehen, und die Rohre sich gegenseitig überdecken und sich dadurch abschatten.However, all the designs described have the common disadvantage that there are non-luminous zones between the tubes, and the tubes overlap one another and thereby shade themselves.

Um die angeführten Nachteile zu vermeiden, wird erfindungsgemäß vorgeschlagen, das Gasentladungsgefäß der Kompaktlampe aus einer Außenhülle (2), welche etwa dem Außendurchmesser der Kompaktlampe entspricht, aufzubauen und nicht, wie bisher, aus einer Kombination von dünnen Rohren, wobei die erforderlichen Elektrodenanschlüße derart angeordnet sind, daß sie direkt mit dem Vorschaltgerät, aber lösbar, in einfacher Weise zu einer kompletten Kompaktlampe verbunden werden können.In order to avoid the disadvantages mentioned, it is proposed according to the invention to construct the gas discharge vessel of the compact lamp from an outer envelope (2), which corresponds approximately to the outer diameter of the compact lamp, and not, as previously, from a combination of thin tubes, the necessary electrode connections being arranged in this way are that they can be connected directly to the ballast, but releasably, in a simple manner to form a complete compact lamp.

Damit erzielt man eine geschlossene Leuchtfläche mit beser Ausnutzung der Oberfläche. Die sonst vorhandenen Zwischenräume entfallen und die geschlossene Außenhülle kann einfach gereinigt werden, was bei den bisherigen Kompaktlampen fast unmöglich ist und zubaldigen Lichteinbußen führte.This creates a closed illuminated surface with the best use of the surface. The otherwise existing gaps are omitted and the closed outer shell can be easily cleaned, which is almost impossible with the previous compact lamps and led to loss of light at an early stage.

Um die Gasentladung und ihre gleichmäßige Verteilung optimal zu gestalten, wird vorgeschlagen, die erste der beiden erforderlichen Elektrode auf einer Seite der Außenhülle (2) anzuordnen und die zweite Elektrode (5) auf der gegenüberliegenden Seite der Außenhülle vorzusehen, wobei deren Anschluß (6) über ein abgedichtetes, möglichst zentral gelegenes Innenrohr (8) nach außen geführt wird, vorzugsweise in Richtung des Anschlußes (4) der ersten Elektrode (3).In order to optimally design the gas discharge and its uniform distribution, it is proposed to arrange the first of the two required electrodes on one side of the outer shell (2) and to provide the second electrode (5) on the opposite side of the outer shell, the connection (6) of which is led to the outside via a sealed, preferably centrally located inner tube (8), preferably in the direction of the connection (4) of the first electrode (3).

Der Durchmesser des Innenrohres (8) wird erfindungsgemäß so gewählt, daß sich zwischen Innenrohr (8) und Außenhülle (2) ein optimaler Abstand von maximal 12 mm ergibt. Das sichert erfahrungsgemäß gute Eigenschften der Gasentladung, aber eine solche Dimension gestattet auch die Unterbringung von Teilen des Vorschaltgerätes (7) innerhalb des Innenrohres (8) und ermöglichst günstigere Baulängen der Kompaktlampe.The diameter of the inner tube (8) is chosen according to the invention so that there is an optimal distance of a maximum of 12 mm between the inner tube (8) and the outer shell (2). Experience has shown that this ensures good properties of the gas discharge, but such a dimension also allows parts of the ballast (7) to be accommodated within the Inner tube (8) and enables cheaper lengths of the compact lamp.

Kostensparend wirkt sich auch die erfindungsgemäße Konstruktion aus, nur die Innenseite der Außenhülle (2) mit einem teuren Leuchtstoffbelag (9) zu beschichten. Das Innenrohr (8) muß nicht mit einem Leuchtstoffbelag versehen werden. Es wird vielmehr empfohlen, das Innenrohr (8) mit einem gut reflektierenden belag zu versehen, welcher die Intensität der bestrahlung des Leuchtstoffbelages erhöht.The construction according to the invention also has a cost-saving effect if only the inside of the outer shell (2) is coated with an expensive fluorescent coating (9). The inner tube (8) does not have to be provided with a fluorescent coating. Rather, it is recommended to provide the inner tube (8) with a well reflective coating, which increases the intensity of the irradiation of the fluorescent coating.

Ein innenseitiger elektrisch leitender Belag am Innenrohr (8) kann durch seinen elektrostatischen Einfluß auf den Zündvorgang diesen begünstigen und stellt eine weitere Verbesserungsmöglichkeit der Erfindung dar. Eine derartige unsichtbare Anbringung eines Belages zur Zündhilfe ist bei den bisherigen Konstruktionen nicht möglich.An electroconductive coating on the inside of the inner tube (8) can favor it by its electrostatic influence on the ignition process and represents a further possibility for improvement of the invention. Such an invisible application of a coating for ignition aid is not possible with previous designs.

Die rotationssymmetrische Form eines erfindungsgemäßen Gasentladungsgefäßes begünstigt die Anordnung von ringförmigen Elektroden. Besonders die Elektrode (3) läßt sich vorteilhaft entweder als Drahtring, oder als gewendelter Drahtring bei beheizten Elektroden, oder auchals aufgedampfte leitende Schicht ausführen, welche sogar eine einfache Beheizung in bekannter Art gestattet.The rotationally symmetrical shape of a gas discharge vessel according to the invention favors the arrangement of annular electrodes. In particular, the electrode (3) can advantageously be implemented either as a wire ring, or as a coiled wire ring in the case of heated electrodes, or as a vapor-deposited conductive layer, which even allows simple heating in a known manner.

Unter bestimmten Voraussetzungen, bei hohen Qualitätsanforderungen ist es zweckmäßig, die Ringelektrode (10) in mehrere Segmente (11) aufzuteilen und jedem Segment (11) Anschlüße (12) zuzuordnen.Under certain conditions and with high quality requirements, it is expedient to divide the ring electrode (10) into several segments (11) and to assign connections (12) to each segment (11).

Diese Segmente können entweder von dem Vorschaltgerät zyklisch in schneller Folge angesteuert werden, oder sie können gemeinsam oder in Gruppen über elektrische Kopplungselemente (13) geschaltet werden. Als Kopplungselement (13) kommen sowohl induktive als auch ohmsche oder kapazitive Verbindungen in Frage, welche sich besonders bei einem Aufdampfen der Segmente (11) einfachst und kostengünstig herstellen lassen.These segments can either be controlled cyclically in rapid succession by the ballast, or they can be switched together or in groups via electrical coupling elements (13). Both inductive and ohmic or capacitive connections can be used as the coupling element (13), which are simple and inexpensive to produce, particularly when the segments (11) are vapor-deposited to let.

Eine weitere erfindungsgemäße Maßnahme zur Homogenisierung der Entladung besteht darin, zumindest an einer Elektrode eine Art Ionisierungskammer in Form eines Hohlraumes (14) vorzusehen. Eine solche Ionisierungskammer begünstigt bei Wechselstrombetrieb die Aufrechterhaltung der Entladung, aber auch eine bessere räumliche Verteilung derselben.A further measure according to the invention for homogenizing the discharge consists in providing a type of ionization chamber in the form of a cavity (14) at least on one electrode. Such an ionization chamber promotes the maintenance of the discharge in AC operation, but also a better spatial distribution of the same.

Auch die Beheizung der Elektroden ist erfindungsgemäß ohne weiteres möglich, sofern man die zusätzlich erforderlichen Heizanschlüße (15,16) vorsieht. Das gleiche gilt für zusätzliche Zündelektroden (17).According to the invention, heating of the electrodes is also readily possible, provided that the additionally required heating connections (15, 16) are provided. The same applies to additional ignition electrodes (17).

Die nachfolgende Beschreibung von Ausführungsbeispielen ist in keiner Weise als umfassend oder beschränkend aufzufassen, sondern dient lediglich zur besseren Darstellung des Erfindungsgedankens.The following description of exemplary embodiments is in no way to be considered comprehensive or restrictive, but merely serves to better illustrate the concept of the invention.

Die Fig. 1 bis 6 zeigen bisherige Ausführungsformen von Kompaktlampen, die meist mit Leuchtrohren (18) in Stab- oder Wendelform ausgeführt wurden. Die lichttechnisch nicht genutzten Zwischenräume (22) sind klar erkennbar, ebenso die gegenseitige Abschattung der sich überdeckenden Leuchtröhren (18).1 to 6 show previous embodiments of compact lamps, which were mostly carried out with light tubes (18) in the form of rods or filaments. The spaces (22) not used in terms of lighting technology are clearly recognizable, as is the mutual shading of the overlapping fluorescent tubes (18).

Die Ausführung Fig. 5 zeigt die mögliche räumliche Verkürzung der Baulänge einer Kompaktlampe, indem man einen Teil (22) des Vorschaltgerätes (7) in die Wendel eintauchen läßt.5 shows the possible spatial reduction in the overall length of a compact lamp by allowing a part (22) of the ballast (7) to be immersed in the filament.

Den Beispielen ist gemeinsam, daß das Vorschaltgerät (7) mit dem Sockel (20) zum Einsetzen in eine Fassung fest verbunden ist.The examples have in common that the ballast (7) is firmly connected to the base (20) for insertion into a socket.

Fig. 7 zeigt den Schnitt durch eine Kompaktlampe mit erfindungsgemäßem Gasentladungsgefäß. Die dicht abgeschlossene Außenhülle (2) kann mit den Anschlüßen (4) und (6), welche die beiden Elektroden (3) und (5) mit dem Vorschaltgerät (7) verbinden, an diesem abgesteckt werden. In der schematischen Darstellung Fig. 7 wurden die Anschlüße (4) und (6) als einfache Steckanschlüße gezeichnet, aber jede andere Art der Verbindung als Bajonett-Anschluß oder ähnliche Lösungen sind möglich. Fig. 8 zeigt die klare Form der Kompaktlampe von unten.7 shows the section through a compact lamp with a gas discharge vessel according to the invention. The tightly sealed outer shell (2) can with the connections (4) and (6), which the two electrodes (3) and (5) with the Connect the ballast (7) and unplug it. 7, the connections (4) and (6) were drawn as simple plug connections, but any other type of connection as a bayonet connection or similar solutions are possible. 8 shows the clear shape of the compact lamp from below.

Wesentlich ist die Anordnung der zweiten Elektrode (5) am unteren Ende des Innenrohres (8), um eine gleichmäßige Ausbildung der Gasentladung zu erreichen. Der zugehörige Anschluß (6) ist im Innenrohr (8) mit der Elektrode (5) verbunden.The arrangement of the second electrode (5) at the lower end of the inner tube (8) is essential in order to achieve a uniform formation of the gas discharge. The associated connection (6) is connected to the electrode (5) in the inner tube (8).

Fig. 9 zeigt ein wesentlich verbessertes Beispiel eines erfindungsgemäßen Gasentladungsgefäßes. In diesem Beispiel ist das Volumen des Entladungsraumes durch einen größeren Radius des Innenrohres (8) verringert. Der Abstand zwischen Innenrohr (8) und Außenhülle (2) ist verkleinert. Billigeres Evakuieren und Füllen mit Gas ist die Folge.9 shows a significantly improved example of a gas discharge vessel according to the invention. In this example, the volume of the discharge space is reduced by a larger radius of the inner tube (8). The distance between the inner tube (8) and outer shell (2) is reduced. The result is cheaper evacuation and filling with gas.

Das Innenrohr (8) ist mit einer Beschichtung (21) versehen, die mehrere Aufgaben erfüllen kann. Als elektrisch leitende Schicht begünstigt sie kapazitiv das Zündverhalten der Gasentladung. Als gut reflektierende Schicht reflektiert sie die im Gasentladungsraum auftretende Ultraviolettstrahlung und regt den Leuchtstoffbelag (9) zur intensiveren Lichtabgabe an. Eine höhere Lichtausbeute ist die Folge.The inner tube (8) is provided with a coating (21) that can perform several tasks. As an electrically conductive layer, it capacitively favors the ignition behavior of the gas discharge. As a highly reflective layer, it reflects the ultraviolet radiation occurring in the gas discharge space and stimulates the fluorescent coating (9) to emit more intensively. The result is a higher luminous efficacy.

Da nur die Außenhülle (2) einen Leuchtstoffbelag (9) besitzt, werden nur tatsächlich Licht aussendende Flächen beschichtet und bisher abgedeckte oder abgeschattete Teilflächen nicht unnötig mit den sehr teuren Leuchtstoffen belebt. Eine weitere Kostensenkung ist die Folge.Since only the outer cover (2) has a fluorescent coating (9), only areas that actually emit light are coated and previously covered or shaded partial areas are not unnecessarily revitalized with the very expensive phosphors. The result is a further cost reduction.

Die in Fig. 9 schematisch als aufgedampfte, ringförmige Elektrode (10) mit ihren Anschlüßen (12) hat direkte Verbindung zum Vorschaltgerät (7), welches auch über den Anschluß (6) mit der Eletrode (5) in Verbindung steht.The schematic in FIG. 9 as a vapor-deposited annular electrode (10) with its connections (12) has a direct connection to the ballast (7), which is also connected to the electrode (5) via the connection (6) stands.

Auch der schematisch dargestellte Hohlraum (14) im Bereich der Elektrode (5) begünstigt die Gasentladung. Er stellt eine Ionisierungskammer dar, welche eine gleichförmige Funktion fördert.The schematically represented cavity (14) in the area of the electrode (5) also favors gas discharge. It represents an ionization chamber that promotes a uniform function.

Der Fig. 9 ist klar zu entnehmen, daß infolge der Unterbringung von Teilen des Vorschaltgerätes (7) im Innenrohr (8) die gesamte Baulänge der Kompaktlampe (1) verkleinert werden kann.9 clearly shows that the overall length of the compact lamp (1) can be reduced as a result of accommodating parts of the ballast (7) in the inner tube (8).

Fig. 10 zeigt ein schematisches Schaltbild einer ringförmigen Elektrode (10), welche in mehrere Segmente (11) unterteilt ist. Jedes Segment (11) hat einen Anschluß (12), welcher mit dem Vorschaltgerät (7) in Verbindung steht. Das Vorschaltgerät (7) steuert die einzelnen Segmente in schneller Folge zyklisch an, so daß die den Segmenten (11) zugeordneten Bereiche der Gasentladung flimmerfrei beaufschlagt werden.Fig. 10 shows a schematic circuit diagram of an annular electrode (10) which is divided into several segments (11). Each segment (11) has a connection (12) which is connected to the ballast (7). The ballast (7) controls the individual segments cyclically in rapid succession, so that the areas of the gas discharge assigned to the segments (11) are acted upon without flickering.

Fig. 11 zeigt eine andere Variante der Ansteuerung der Segmente (11). In diesem Beispiel sind die Segmente (11) durch Kopplungselemente (13) verbunden, so daß sie unabhängig voneinander arbeiten können.Fig. 11 shows another variant of the control of the segments (11). In this example, the segments (11) are connected by coupling elements (13) so that they can work independently of one another.

Fig. 12 zeigt ebenfalls schematisch, daß auch die Beheizung der Elektroden (3) oder (5) ohne weiteres möglich ist. Es sind lediglich zusätzliche Heizanschlüße (15,16) erforderlich.Fig. 12 also shows schematically that heating of the electrodes (3) or (5) is also easily possible. Only additional heating connections (15, 16) are required.

Auch zusätzliche Zündelektroden (17) sind in bekannter Art möglich und in Fig. 12 schematisch dargestellt.Additional ignition electrodes (17) are also possible in a known manner and are shown schematically in FIG. 12.

Aus den Beispielen sind die Erfindungsgedanken gut erkennbar und die allgemeine breite Auslegung der Erfindung deutlich. Alle bisher üblichen Konstruktionen können unbeschränkt angewendet werden. Sei es in der Art der Steckverbindungen, oder in bezug auf die Schaltbilder der elektronischen Vorschaltgeräte oder der verschiedenen Fassungen. Auch die verwendeten Materialien für die Bauteile, ob Glas, Kunststoff oder Metall, sind dem Konstrukteur überlassen.The ideas of the invention can be clearly seen from the examples and the general broad interpretation of the invention is clear. All constructions that have been common until now can be used without restriction. Be it in the type of connectors, or in relation to the wiring diagrams of the electronic ballasts or the various versions. The materials used for the components, whether glass, plastic or metal, are also left to the designer.
