Description

Reflektor ohne Belüftungsöffnungen, Verfahren zur Herstellung desselben und Verwendung des Reflektors Reflector without ventilation openings, method of manufacturing the same and use of the reflector

Beschreibungdescription

Die Erfindung betrifft einen Reflektor, bei dem kein Licht aus Belüftungsschlitzen austritt und bei dem die Geräuschentwicklung stark verringert wird, ferner ein Verfahren zu seiner Herstellung und seiner Verwendung.The invention relates to a reflector in which no light emerges from ventilation slots and in which the noise is greatly reduced, further to a method for its production and its use.

Die Reflektoren besitzen im Allgemeinen eine elliptische, parabolische oder kegelschnittähnliche Grundkontur. Sie können Glas oder Glas- Keramik als Substrat enthalten. Als Lampen werden Gasentladungsleuchtkörper verwendet; diese stehen unter einem hohen Innendruck von bis zu 2*105 hPa. Sie haben zwar zahlreiche technologische Vorteile, jedoch ist ihre Lebensdauer durch thermochemische Einflüsse begrenzt. Im allgemeinen liegt die Lebensdauer in der Größenordnung von 2000 Stunden. Ein gravierender Nachteil solcher Leuchtkörper besteht darin, dass am Ende ihrer Lebensdauer ihre Zerstörung durch eine Explosion eintritt. Durch die Explosion des Leuchtkörpers wird der Reflektor so stark beschädigt, dass Glassplitter umherfliegen und eine erhebliche Gefahr verursachen. Durch die Explosion können wertvolle optische Komponenten und Bauteile beschädigt werden. Zur Vermeidung der Splitterbildung sind Reflektoren mit großer Wandstärke hergestellt worden. Die Wandstärke beträgt mehr als 4 mm. Durch die hohen thermischen Belastungen treten bei diesen Reflektoren Wärmespannungen auf, die wiederum zu Bruch führen. Die Erhöhung der Wandstärke bringt keine befriedigende Lösung. Bei herkömmlichen Reflektoren tritt Licht aus Belüftungsschlitzen, was sich störend auswirkt. Um die Belüftungsschlitze klein zu halten, müssen Ventilatoren bereitgestellt werden. Das Betreiben der Ventilatoren ist mit Geräuschbelästigung verbunden.The reflectors generally have an elliptical, parabolic or conic-like basic contour. They can contain glass or glass-ceramic as a substrate. Gas discharge lamps are used as lamps; these are under a high internal pressure of up to 2 * 10 5 hPa. Although they have numerous technological advantages, their service life is limited by thermochemical influences. In general, the lifespan is on the order of 2000 hours. A serious disadvantage of such luminous bodies is that they are destroyed by an explosion at the end of their service life. The reflector is so badly damaged by the explosion of the filament that glass fragments fly around and cause considerable danger. The explosion can damage valuable optical components. To avoid splintering, reflectors with a large wall thickness have been manufactured. The wall thickness is more than 4 mm. Due to the high thermal loads, thermal stresses occur in these reflectors, which in turn lead to breakage. Increasing the wall thickness does not bring a satisfactory solution. With conventional reflectors, light emerges from ventilation slots, which has a disruptive effect. To keep the ventilation slots small, fans must be provided. The operation of the fans is associated with noise pollution.

Aus der DE 37 23 245 C2 ist ein Reflektor bekannt, welcher als Spiegelträger einen Sandwichaufbau aufweist. Der Kern besteht aus einem flexiblen Leichtbaukörper auf welchen, um eine formstabile Struktur zu schaffen, auf der Vorder- und Rückseite Kunststoffplatten befestigt sind. Auf der Innenseite kann weiterhin als ebene Unterlage für einen reflektierenden Film oder eine reflektierende Folie ein hartes und glattes Substrat beispielsweise aus Glas oder Metall angebracht werden. Ein solcher Spiegelträger ist in seiner Herstellung relativ aufwendig und kostenintensiv und von der Form her eher instabil. Eine Außenbe- schichtung zur Vermeidung der Splitterbildung bei einer Explosion des Leuchtkörpers oder auch einer Außenbeschichtung zur Vermeidung von Lichttransmission durch den Spiegelträger ist hier nicht erforderlich.From DE 37 23 245 C2 a reflector is known which has a sandwich structure as a mirror support. The core consists of a flexible lightweight body on which plastic plates are attached to the front and back to create a dimensionally stable structure. A hard and smooth substrate, for example made of glass or metal, can also be attached to the inside as a flat base for a reflective film or film. Such a mirror support is relatively complex and expensive to manufacture and its shape is rather unstable. An outer coating to avoid splintering in the event of an explosion of the luminous element or an outer coating to avoid light transmission through the mirror carrier is not necessary here.

Aus der DE 44 26 843 A1 ist die Verwendung von Fluorpolymer als Werkstoff bekannt. Aufgabe ist hier die Bereitstellung eines elektrischen Substratmaterials mit hoher Dieelektrizitätskonstante und niedrigem Wärmekoeffizient der Elektrizitätskonstante als Träger von Mikrowellenschaltungen. Hierzu wird das Fluorpolymer als Matrix neben verschiedenen möglichen Keramikpulvern auch mit Hartglaspulver zu einem Fluorpolymer-Keramikverbundwerkstoff vermischt.DE 44 26 843 A1 discloses the use of fluoropolymer as a material. The task here is to provide an electrical substrate material with a high dielectric constant and a low heat coefficient of the electricity constant as a carrier for microwave circuits. For this purpose, the fluoropolymer is mixed as a matrix in addition to various possible ceramic powders and also with hard glass powder to form a fluoropolymer-ceramic composite material.

Die Aufgabe der Erfindung besteht darin, einen Reflektor aus Glas oder Glaskeramik bereitzustellen, bei dem kein Licht aus Belüftungsschlitzen austritt und keine Kühlung durch Ventilatoren erforderlich ist, femer der Reflektor stabil bleibt bei einer explosiven Zerstörung des Leuchtkörpers, ferner ein Verfahren zu seiner Herstellung und zu seiner Verwendung anzugeben. Die Aufgabe der Erfindung wird durch einen Reflektor gemäß Anspruch 1 gelöst, ein Verfahren zur Herstellung des Reflektor ist durch Anspruch 8 gegeben und seine Verwendung durch den Anspruch 11.The object of the invention is to provide a reflector made of glass or glass ceramic, in which no light emerges from ventilation slots and no cooling by fans is required, furthermore the reflector remains stable in the event of an explosive destruction of the luminous element, furthermore a method for its production and indicate its use. The object of the invention is achieved by a reflector according to claim 1, a method for producing the reflector is given by claim 8 and its use by claim 11.

Gemäß der Erfindung wird ein Reflektor der eingangs genannten Art mit einer Beschichtung versehen. Die Beschichtung besteht aus einem Polymer, das hochtemperaturbeständig ist und das eine über den Reflektorumfang zusammenhängende Schicht bildet. Dabei braucht nicht unbedingt die gesamte Reflektoraußenfläche von der Polymerschicht bedeckt zu sein. Es kann auch genügen, einen Polymerschichtring um den Reflektor zu legen, der sich - in axialer Richtung des Reflektors gesehen - über den notwendigen Teil der Reflektorfläche hinweg erstreckt. Durch die nichttransparente Schicht wird verhindert, daß Licht durch Belüftungsschlitze austritt. Es werden auch weniger oder kleine Ventilatoren benötigt, wodurch die Geräuschentwicklung verringert wird.According to the invention, a reflector of the type mentioned at the outset is provided with a coating. The coating consists of a polymer that is resistant to high temperatures and that forms a coherent layer over the circumference of the reflector. The entire outer surface of the reflector need not necessarily be covered by the polymer layer. It may also be sufficient to place a polymer layer ring around the reflector, which — viewed in the axial direction of the reflector — extends over the necessary part of the reflector surface. The non-transparent layer prevents light from escaping through ventilation slots. Fewer or smaller fans are also required, which reduces noise.

Die Polymerschicht enthält insbesondere ein Fluorpolymer. Fluorpolymere haben sich als besonders temperaturbeständig erwiesen. Bei einer Explosion wird durch das Fluorpolymer das Herumfliegen von Splitter vermieden. Die Fluorpolymerschicht hält dem stärksten Explosionsdruck stand.The polymer layer contains in particular a fluoropolymer. Fluoropolymers have proven to be particularly temperature-resistant. In the event of an explosion, the fluoropolymer prevents splinters from flying around. The fluoropolymer layer withstands the strongest explosion pressure.

Die nichttransparente Schicht enthält mindestens einen der nachfolgenden Bestandteile, wie Lack, Primer oder Polymer. Durch Spritzen oder Tauchen wird eine nichttransparente Schicht von etwa 5 μm bis 30 μm aufgebracht. Die Schicht hat eine Dichte, die Austreten des Lichtes verhindert.The non-transparent layer contains at least one of the following components, such as lacquer, primer or polymer. A non-transparent layer of approximately 5 μm to 30 μm is applied by spraying or dipping. The layer has a density that prevents the light from escaping.

Die ursprüngliche Funktion des Reflektors, nämlich die Infraroten Strahlen seitlich herauszuführen, wird durch die Fluorpolymerschicht in keiner Weise beeinträchtigt. Der aufgrund dieser Funktion so genannte Kaltlichtreflektor kann wie vorgesehen verwendet werden. Der außenbeschichtete Kaltlichtreflektor hat somit eine große wirtschaftliche Bedeutung.The fluoropolymer layer in no way affects the original function of the reflector, namely to guide the infrared rays out to the side. The so-called because of this function Cold light reflector can be used as intended. The externally coated cold light reflector is therefore of great economic importance.

Die Polymerschichtdicke beträgt von 5 μm bis 200 μm, bevorzugt von 50 μm bis 180 μm und besonders bevorzugt von 80 μm bis 170 μm. Bei den nicht explosionsgefährdeten Bereichen genügt eine Schichtdicke bevorzugt von 35 μm bis 50 μm. In Bereichen, die explosionsgefährdet sind, beträgt die Schichtdicke bevorzugt von 120 μm bis 170 μm. Der Hals des Reflektors ist vorzugsweise nicht beschichtet.The polymer layer thickness is from 5 μm to 200 μm, preferably from 50 μm to 180 μm and particularly preferably from 80 μm to 170 μm. In the non-hazardous areas, a layer thickness of preferably 35 μm to 50 μm is sufficient. In areas that are at risk of explosion, the layer thickness is preferably from 120 μm to 170 μm. The neck of the reflector is preferably not coated.
