A funnel-shaped metal heat shield body is disposed inside the domelike bulge and spaced apart from the bulb cover.

Description

Die Erfindung betrifft eine mit einer auf einem Rohrmast oder dergleichen senkrechten Träger angeordneten Leuchtenhalterung insbesondere für Straßen- oder dergleichen Außenleuchten lösbar verbundene Lampenabdeckung, bestehend aus einem die Lampe umgebenden Leuchtenglas aus Kunststoff, einem innerhalb desselben in Höhe der Lampe angeordneten Blendring aus Metall, einem oberhalb der Lampe außerhalb des Leuchtenglases angeordneten und in seinem zentralen Bereich vom Lampenglas durchdrungenen und überragten Leuchtendach und einem innerhalb des Leuchtenglases in dessen das Leuchtendach überragenden Teil angeordneten trichterförmigen Wärmeschutzkörper aus Metall.The invention relates to a lamp cover detachably connected to a lamp holder arranged on a tubular mast or the like, in particular for street or similar exterior lights, consisting of a lamp glass made of plastic surrounding the lamp, a metal cover ring arranged inside the lamp at the level thereof, one above the lamp arranged outside the lamp glass and in its central area penetrated and surmounted by the lamp glass and a lamp funnel-shaped heat protection body made of metal arranged inside the lamp glass in its part projecting beyond the lamp roof.

Lampenabdeckungen mit diesen Merkmalen sind bereits in verschiedenen Ausführungsformen im Handel und daher allgemein bekannt. In einer Werbeschrift der Firma NORAL LABEL, la SEYNE-SUR-MER, Frankreich, wird eine Außenleuchte mit einer derartigen Lampenabdeckung feilgeboten. Ähnliche Leuchten werden auch von anderen Firmen, z.B. in einer Werbeschrift der Firma HESS-FORM + LICHT in Villingen-Schwenningen, und in einem Katalog der Firma Hellux-Leuchten GmbH in Laatzen.Lamp covers with these features are already commercially available in various embodiments and are therefore general known. In an advertising brochure from NORAL LABEL, la SEYNE-SUR-MER, France, an outdoor lamp with such a lamp cover is offered for sale. Similar lights are also used by other companies, for example in an advertising lettering from HESS-FORM + LICHT in Villingen-Schwenningen, and in a catalog from Hellux-Leuchten GmbH in Laatzen.

Der in Höhe der Lampe angeordnete Blendring soll Direktblendungen verhindern. Um dadurch nicht die Beleuchtungswirkung zu beeinträchtigen, sind die Blendringe in verschiedenen Ausführungen in gewisser Weise lichtdurchlässig, z.B. dadurch, daß sie aus konischen Ringscheiben mit nach unten gerichteten Außenrändern zusammengesetzt sind (HELLUX). So ist die Lampe nur aus geringer Entfernung vom Standort der Leuchte bei nach oben gerichtetem Blick sichtbar.The glare ring located at the height of the lamp is intended to prevent direct glare. In order not to impair the lighting effect as a result, the bezel rings in various versions are somewhat translucent, e.g. in that they are composed of conical washers with outer edges facing downwards (HELLUX). So the lamp is only visible from a short distance from the location of the lamp when looking upwards.

Der über der Lampe angeordnete trichterförmige Wärmeschutzkörper (NORAL) hält die besonders nach oben gerichtete Wärmeabgabe der Lampe Von diesem Bereich der Lampenabdeckung fern.
Bei der Leuchte von NORAL ist die Lampenabdeckung, z.B. zum Auswechseln der Lampe, in der Weise abnehmbar, daß sie durch eine seitliche Gelenkhalterung mit dem Leuchtenunterteil seitlich abkippbar verbunden ist.
Die bekannten Leuchten dieser Art sind konstruktiv sehr aufwendig. Sie bestehen aus einer Vielzahl von Bauteilen. Für ihre Herstellung und Montage wird eine ganze Reihe von Arbeitsgängen benötigt. Dadurch sind solche Leuchten schon durch die Lampenabdeckung allein sehr teuer.The funnel-shaped heat protection body (NORAL) arranged above the lamp keeps the lamp's particularly upward heat emission away from this area of the lamp cover.
With the lamp from NORAL, the lamp cover can be removed, for example, to replace the lamp, in such a way that it is connected to the lower part of the lamp by means of a side hinge bracket.
The known lights of this type are very expensive to construct. They consist of a large number of components. A whole series of operations are required for their manufacture and assembly. As a result, luminaires of this type are very expensive even by the lamp cover alone.

Der Erfindung liegt die Aufgabe zugrunde, eine Lampenabdeckung für eine Außenleuchte, insbesondere Mast-Aufsetzleuchte zu schaffen, die leicht und schnell lösbar mit der auf einem Rohrmast oder dergleichen Träger angeordneten Leuchtenhalterung verbunden ist, die konstruktiv einfacher ist, aus weniger Einzelteilen besteht, in weniger Arbeitsgängen herstellbar und montierbar ist und die ohne Nachteile hinsichtlich der Leuchtwirkung und materieller Qualität billiger ist, als die bekannten Lampenabdeckungen bei Leuchten dieser Gattung.The invention has for its object to provide a lamp cover for an outdoor lamp, in particular pole-mounted lamp, which is easily and quickly detachable with the lamp holder arranged on a pole or similar support is connected, which is structurally simpler, consists of fewer individual parts, can be produced and assembled in fewer work steps and which is cheaper without disadvantages with regard to the lighting effect and material quality than the known lamp covers for lamps of this type .

Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Lampenabdeckung für eine in der Beschreibungseinleitung und im Oberbegriff des Anspruchs 1 definierten Leuchtengattung mit den Merkmalen gemäß dem kennzeichnenden Teil des Anspruchs 1 ausgestattet ist. Weitere Merkmale der Erfindung gehen aus den Ansprüchen 2 bis 9 hervor.The object is achieved in that a lamp cover for a lamp type defined in the introduction and in the preamble of claim 1 is equipped with the features according to the characterizing part of claim 1. Further features of the invention emerge from claims 2 to 9.

Die erfindungsgemäße Lampenabdeckung besteht im wesentlichen aus einem als einstückiger, oben geschlossener Hohlkörper ausgebildeten Leuchtenglas 1 aus einem thermoplastischen Kunststoff, einem in dem Leuchtenglas 1 in Höhe der Lampe 2 angeordneten Blendring 3, einem über der Lampe 2 in dem Leuchtenglas 1 angeordneten Wärmeschutzkörper 4 und einem am Lampenglas 1 in dessen oberem Bereich angeordneten Leuchtendach 5.The lamp cover according to the invention essentially consists of a luminaire glass 1 formed as a one-piece, hollow body closed at the top, made of a thermoplastic, one in the luminaire glass 1 in height of the lamp 2 arranged diaphragm ring 3, a cylinder disposed in the lamp glass 1 via the lamp 2 thermal insulation body 4 and, arranged in the upper region of the lantern lens 1 Canopy. 5

Das Lampenglas 1 ist bei dem dargestellten Ausführungsbeispiel ein im wesentlichen zylindrischer Hohlkörper aus einem Polykarbonat. Er weist in Höhe der Lampe 2 eine Erweiterung 6 seines Querschnittes in Form einer breiten Ringnut auf. Darin ist der Blendring 3 an der Innenwand des Lampenglases 1 anliegend gehalten.
Der Blendring 3 besteht aus einem Metallblech. Er hat bei diesem Ausführungsbeispiel der einfacheren Darstellung wegen die Form eines einfachen glatten Zylinders. Wenigstens einer seiner Ränder kann nach außen gewinkelt sein, so daß das von der Lampe 2 erwärmte Blech nicht mit seiner ganzen Fläche, sondern nur mit schmalen Zonen die Innenwand des Leuchtenglases berührt. Er kann aber auch in der Weise weitergebildet sein, daß seine Wand ein System von auf Ringlinien jeweils paarweise versetzt zueinander angeordneten Schlitzen aufweist, wobei die jeweils zwischen zwei übereinanderliegenden Schlitzen befindlichen Wandflächen gegen die Zylinderachse geneigt sind und so jeweils einen Kreissektor eines Kegelmantelsegmentes bilden.
Der Blendring 3 kann beispielsweise auch raffelblechartig mit abwärts nach außen gerichteten Raffelrändern ausgebildet sein. Die beiden letztgenannten Ausführungsformen haben den Vorteil, daß mit der durch das Schlitzsystem möglichen Wahl der Neigung der Wandabschnitte des Blendringes 3 ein Optimum wählbar ist zwischen einer möglichst weiten Bodenbeleuchtung einerseits und der Abblendung waagerechter Lichtstrahlung andererseits.The lamp glass 1 in the illustrated embodiment is an essentially cylindrical hollow body made of a polycarbonate. At the level of the lamp 2, it has an extension 6 of its cross section in the form of a wide annular groove. In it, the blind ring 3 is held against the inner wall of the lamp glass 1 .
The blind ring 3 consists of a metal sheet. It has the shape of a simple smooth cylinder in this embodiment for simplicity of illustration. At least one of its edges can be angled outwards, so that the metal sheet heated by the lamp 2 does not touch the entire surface of the lamp surface, but only the narrow wall of the lamp glass. However, it can also be developed in such a way that its wall has a system of slots which are arranged in pairs offset from one another on ring lines, the wall surfaces located between two slots lying one above the other being inclined against the cylinder axis and thus in each case forming a circular sector of a conical jacket segment.
The blind ring 3 can, for example, also be designed in the manner of a scraper with downward outward scraper edges. The two last-mentioned embodiments have the advantage that with the choice of the inclination of the wall sections of the blind ring 3 which is possible through the slot system, an optimum can be selected between the greatest possible floor lighting on the one hand and the dimming of horizontal light radiation on the other hand.

Das Leuchtenglas 1 weist oben eine zentrale domförmige Erhöhung 7 auf, die aus einer zentralen Öffnung des Leuchtendaches 5 herausragt. Darin ist der Wärmeschutzkörper 4 angeordnet. Dieser ist als trichterartiges Formteil aus Metallblech ausgebildet und mit Abstand zur Innenwand des Leuchtenglases 1 mittels an seinem oberen Rand angeordneter, von dort abwärts gerichteter und mit ihren Enden radial abgewinkelter Stege 8 am Leuchtenglas 1 befestigt. Als Befestigungsmittel sind Schrauben 9 vorgesehen, die von außen durch den inneren Randbereich des Leuchtendaches 5, den Schulterbereich des Leuchtenglases 1 und Bohrungen in den Enden der Stege 8 gesteckt sind. Dabei ist jeweils zwischen der Wand des Leuchtenglases 1 und der das Stegende haltenden Schraubenmutter 9a eine Scheibe 9b aus wärmedämmendem Material auf die Schraube 9 gesteckt.The lamp glass 1 has a central dome-shaped elevation 7 at the top, which emerges from a central opening of the Luminous roofs 5 protrudes. The heat protection body 4 is arranged therein. This is formed as a funnel-like molding made of sheet metal and fastened with distance from the inner wall of the luminaire case 1 by means arranged on its upper edge, from there downward and with their ends radially angled webs 8 on the lamp glass. 1 Screws 9 are provided as fastening means, which are inserted from the outside through the inner edge area of the lamp roof 5 , the shoulder area of the lamp glass 1 and bores in the ends of the webs 8 . In this case, a washer 9b made of heat-insulating material is placed on the screw 9 between the wall of the lamp glass 1 and the screw nut 9a holding the web.

Das Leuchtenglas 1 ist mittels einer Bajonettverbindung auf der Leuchtenhalterung 10 befestigt. Dazu weist das unten auf einen kurzen Randabschnitt 11 mit geringerem Durchmesser reduzierten Leuchtenglas 1 kreissektorförmige Flanschabschnitte 12 auf, deren Oberseiten jeweils eine in gleicher Richtung ansteigende schiefe Ebene bilden, wobei zwischen den zwei benachbarten Flanschabschnitten 12 jeweils eine Lücke 13 vorgesehen ist. Als Gegenstück der Bajonettverbindung ist die Leuchtenhalterung 10 oben mit einem zylindrischen Außenrand 14 versehen, an dessen Innenseite in den Abständen der Lücken 13 zwischen den Flanschabschnitten 12 des Leuchtenglases 1 Nocken 15 angeordnet sind. Diese übergreifen bei Drehung des aufgesetzten Leuchtenglases 1 dessen Flanschabschnitte 12 und halten es unter Keilklemmwirkung auf der Leuchtenhalterung 10 fest.The lamp glass 1 is fastened to the lamp holder 10 by means of a bayonet connection. For this purpose, the lamp glass 1, reduced to a short edge section 11 with a smaller diameter, has circular sector-shaped flange sections 12 , the upper sides of which each form an inclined plane rising in the same direction, a gap 13 being provided between each of the two adjacent flange sections 12 . As a counterpart of the bayonet connection, the lamp holder 10 is provided at the top with a cylindrical outer rim 14 on the inner side in the spacings of the gaps 13 between the flange portions 12 of the lamp glass 1 cams 15 are arranged. When the attached lamp glass 1 rotates, it overlaps its flange sections 12 and holds it firmly on the lamp holder 10 with wedge clamping action.

Die Erfindung beschränkt sich nicht auf das vorbeschriebene und in der Zeichnung dargestellte Ausführungsbeispiel und die erwähnten alternativen Formen des Blendringes. So können insbesondere das Leuchtenglas 1 und das Leuchtendach 5 auch andere Formen haben, in denen die Merkmale gemäß Anspruch 1 enthalten sind.The invention is not limited to the embodiment described above and shown in the drawing and the alternative forms of the blind ring mentioned. In particular, the lamp glass 1 and the lamp roof 5 can also have other shapes in which the features according to claim 1 are included.
