Abstract

The lamp excites a gas located in it through electronically produced microwave radiation, causing an emission of light. A pulsed production of the microwave radiation higher than 2 W is performed, and the microwave transmitter is positioned in the interior of the lamp. A metal wire mesh or perforation mask with holes of less than approx. 1/2 (half the wavelength of the radiation) is pref. arranged inside or outside the lamp. The interior of the lamp is pref. coated with a fluorescence layer, and filled optionally with xenon gas.

Description

Die Erfindung betrifft einen Leuchtkörper, der mittels Mikrowellen ein Gas zum Leuchten anregt. Dabei wird die Mikrowellenstrahlung elektronisch erzeugt. Damit sind kleine Leistungen ab einigen Watt bis etwa 100 Watt realisierbar.The invention relates to a luminous element which uses a microwave to generate a gas Lights up. The microwave radiation is generated electronically. With that Small outputs from a few watts to about 100 watts can be achieved.

Bisherige Mikrowellenlampen arbeiten mit röhrenerzeugten Mikrowellen hoher Leistung im kWatt-Bereich.Previous microwave lamps work higher with tube-generated microwaves Power in the kWatt range.

Das Hauptproblem bisheriger Lampen ist der geringe (Licht-) Wirkungsgrad bzw. bei elektrodenbehafteten Röhren die beschränkte Haltbarkeit infolge der Glühdrähte. Ein weiterer Nachteil bisheriger Lampen ist ihre Anfälligkeit bei Erschütterungen. Diese Probleme werden durch die neuentwickelte Lampe gelöst, da sie ohne Elektroden und Glühdrähte auskommt. Sollte ein elektronisches Bauteil ausfallen, so kann es außerhalb der Lampe ausgewechselt werden.The main problem with previous lamps is the low (light) efficiency or Electrode tubes the limited durability due to the filament. On Another disadvantage of previous lamps is their susceptibility to vibrations. These problems are solved by the newly developed lamp, since it has no electrodes and glow wires gets along. If an electronic component fails, it can be replaced outside the lamp.

Dazu wird vorgeschlagen, ein in einer Lampe befindliches Gas, etwa Xenon, das von Glas umschlossen ist, einer elektronisch erzeugten Mikrowellenstrahlung auszusetzen. Hierdurch wird das Gas zur Lichtemission angeregt.For this purpose, it is proposed to use a gas in a lamp, such as xenon, from Glass is enclosed to be exposed to electronically generated microwave radiation. This stimulates the gas to emit light.

Des weiteren wird vorgeschlagen, die Mikrowellenstrahlung elektronisch gepulst zu erzeugen. Dadurch sind höhere Mikrowellenintensitäten und damit höhere Lichtleistungen möglich.Furthermore, it is proposed that the microwave radiation be electronically pulsed produce. This means higher microwave intensities and thus higher ones Light outputs possible.

Um Platz zu sparen und die Übertragung der Mikrowelle in die Lampe zu vereinfachen, wird vorgeschlalgen, den Mikrowellensender direkt in der Lampe unterzubringen. Bei Autoscheinwerfern etwa kann man dann zwischen zwei Sendern zum Abblendlicht oder Fernlicht umschalten (vgl. Fig. 2). In order to save space and to simplify the transfer of the microwave into the lamp, it is suggested that the microwave transmitter be placed directly in the lamp. In the case of car headlights, for example, you can then switch between two transmitters for low or high beam (see Fig. 2).

Um die elektromagnetische Mikro-Welle durch Reflexion im Inneren der Lampe zu behalten, das Licht jedoch hindurchgelangen zu lassen, wird vorgeschlagen, eine Lochblende mit Lochdurchmesser < λ2 oder ein Metallgitter mit Gitterabstand < λ/2 aus Metall bzw. elektrisch leitfähigem Material an der Lampenöffnung anzubringen, während der übrige Teil von Metall umgeben ist (hierbei ist λ die Wellenlänge der Mikrowellenstrahlung).To the electromagnetic micro-wave by reflection inside the lamp too keep but let the light get through, it is suggested one Pinhole with hole diameter <λ2 or a metal grid with grid spacing <λ / 2 to be attached to the lamp opening from metal or electrically conductive material, while the rest is surrounded by metal (here λ is the wavelength of the Microwave radiation).

Um das je nch Gasart erzeugte UV-Licht in sichtbares Licht umzuwandeln, wird vorgeschlagen, wie bei herkömmlichen Leuchtstofflampen im Inneren der Lampe eine Fluoreszenzschicht aufzutragen.In order to convert the UV light generated per gas type into visible light proposed as a conventional fluorescent lamp inside the lamp Apply fluorescent layer.

Bild 1 zeigt eine solche Lampe, deren lichtaussendende Oberfläche von einer Lochblende L umfaßt wird. Im Inneren der Lampe befindet sich der Mirowellensender S. Figure 1 shows such a lamp, the light-emitting surface of which is enclosed by an aperture L. Inside the lamp is the microwave transmitter S.

Bild 2 zeigt darüber hinaus einen Autoscheinwerfer mit Umschaltmöglichkeit durch S zwischen Abblendlicht durch den Sender S2 bzw. Fernlicht mittels des Mikrowellensenders S1. Die Blende B dient dabei der Abschirmung des Abblendlichtes. M bedeutet last not least den Mikrowellensender. Figure 2 also shows a car headlight that can be switched by S between low beam by transmitter S2 or high beam by microwave transmitter S1. The aperture B serves to shield the low beam. M means last but not least the microwave transmitter.
