Abstract
Das Leuchtenelement (8) in einer Leuchte für ein langgestrecktes oder stabförmiges Leuchtmittel, z.B. eine Leuchtstoffröhre (7) oder eine lineare LED-Anordnung, besteht aus mindestens zwei funktional und materialmässig unterschiedlichen Bereichen, die als coextrudiertes Profil einstückig miteinander verbunden sind.The luminaire element (8) in a luminaire for an elongate or rod-shaped luminous means, e.g. a fluorescent tube (7) or a linear LED array, consists of at least two functionally and materially different areas, which are integrally connected as a co-extruded profile.
Description
[0001] Die Erfindung betrifft ein Leuchtenelement gemäss dem Oberbegriff des Patentanspruchs 1. The invention relates to a lamp element according to the preamble of patent claim 1.
[0002] Leuchten für langgestreckte oder stabförmige Leuchtmittel oder längs angeordnete Punktlichtquellen, z.B. sog. Leuchtstoffröhren oder LEDs, besitzen in der Regel ein Gehäuse, in welchem evtl. Halterungen oder Leuchteneinsätze für die Sockel der Leuchtmittel, sowie für Elemente zum Beeinflussen des vom Leuchtmittel abgestrahlten Lichts vorgesehen sind. Diese im Rahmen dieser Beschreibung als Leuchtenelemente bezeichneten und in das Gehäuse einsetzbaren Teile sind beispielsweise Reflektoren, Diffusorscheiben, Farbfilter etc. Diese Leuchtenelemente bestehen in der Regel aus unterschiedlichen, für ihre jeweilige Funktion geeigneten Materialien. So besteht ein Reflektor, der das vom Leuchtmittel abgestrahlte Licht in die gewünschte Richtung lenken soll, z.B. aus einem opaken Kunststoffmaterial, auf dessen Innenseite eine reflektierende oder streuende Schicht aufgebracht ist. Für den Zweck dieser Beschreibung umfasst der Begriff «Reflektor» somit auch Leuchtenelemente, die das einfallende Licht diffus reflektieren. Eine Diffusorscheibe besteht aus einem transparenten oder semi-transparenten Material, beispielsweise aus Acrylglas oder Polycarbonat. Luminaires for elongated or rod-shaped lamps or longitudinally arranged point light sources, e.g. So-called fluorescent tubes or LEDs usually have a housing in which possibly holders or lamp inserts are provided for the base of the lighting means, and for elements for influencing the light emitted by the light source. These parts, which are referred to as luminaire elements in the context of this description and can be inserted into the housing, are, for example, reflectors, diffuser disks, color filters, etc. These luminaire elements generally consist of different materials suitable for their respective function. Thus, there is a reflector which is intended to direct the light emitted by the illuminant in the desired direction, e.g. from an opaque plastic material, on the inside of which a reflective or scattering layer is applied. For the purposes of this description, the term "reflector" thus includes lighting elements that reflect the incident light diffuse. A diffuser panel is made of a transparent or semi-transparent material, such as acrylic or polycarbonate.
[0003] Gemäss dem Stand der Technik werden die unterschiedlichen Leuchtenelemente je nach ihrer Funktion und ihrem dement-sprechenden Material aus verschiedenen stranggepressten Profilen oder abgekanteten, gerundeten oder anders umgeformten Blechen hergestellt und in das Leuchtengehäuse eingesetzt, wo sie mittels möglichst einfachen Verbindungselementen, vorzugsweise durch Einrasten von Nuten und dergl. an Rippen und dergl., gehalten sind. Somit sind für jedes Leuchtenelement einer Leuchte Haltemittel erforderlich, was einen konstruktiven Aufwand erfordert. According to the prior art, the different lighting elements depending on their function and their dement-speaking material made of different extruded profiles or bent, rounded or otherwise formed sheets and inserted into the light housing, where they by means of simple fasteners, preferably by Engaging grooves and the like. On ribs and the like., Are held. Thus, holding means are required for each lamp element of a lamp, which requires design effort.
[0004] Der Erfindung liegt die Aufgabe zugrunde, den Befestigungsaufwand für Leuchtenelemente in einer Leuchte durch Verringerung der Anzahl von Teilen zu verkleinern und gleichzeitig die Leuchteneffizienz zu erhöhen. The invention has for its object to reduce the cost of fixing lamp components in a lamp by reducing the number of parts and at the same time to increase the luminaire efficiency.
[0005] Erfindungsgemäss wird dies erreicht durch ein Leuchtenelement, das sich durch das kennzeichnende Merkmal des Patentanspruchs 1 auszeichnet. This is achieved by a lighting element, which is characterized by the characterizing feature of claim 1 according to the invention.
[0006] Die neuartige Geometrie ermöglicht eine Lichtreflexion am «Reflektor» und nicht mehr am grauen Alukörper, was eine wesentliche Verbesserung ohne zusätzliche Kosten bedeutet. The novel geometry allows a light reflection on the "reflector" and not on the gray aluminum body, which means a significant improvement without additional costs.
[0007] Im Folgenden ist anhand der beiliegenden Zeichnung ein bevorzugtes Ausführungsbeispiel der Erfindung beschrieben. Die Zeichnung zeigt einen Schnitt senkrecht zur Längsrichtung einer Leuchte für eine Leuchtstoffröhre. In the following, a preferred embodiment of the invention will be described with reference to the accompanying drawings. The drawing shows a section perpendicular to the longitudinal direction of a lamp for a fluorescent tube.
[0008] Ein Gehäuse 1 besitzt einen rechteckigen, unten offenen Querschnitt. An den beiden Seitenwänden sind einander paarweise gegenüber liegende, nach innen ragende Rippen wie folgt angeordnet: etwas oberhalb der Gehäusemitte ein erstes Paar 2 zur Befestigung eines Leuchteneinsatzes 5 für die erforderlichen Sockel 6 einer Leuchtstoffröhre 7; unterhalb der Gehäusemitte ein zweites Paar 3 zur Befestigung eines Leuchtenelements 8; nahe beim unteren Rand der Seitenwände des Gehäuses ein drittes Paar 4 als Anschlag für des Leuchtenelement 8. Alternativ kann der Anschlag auch oberhalb des zweiten Rippenpaares 3 angeordnet sein, was eine Schattenbildung noch weiter verringert. A housing 1 has a rectangular, open at the bottom cross-section. At the two side walls, mutually opposite, inwardly projecting ribs are arranged as follows: slightly above the middle of the housing, a first pair 2 for fixing a lamp insert 5 for the required base 6 of a fluorescent tube 7; below the middle of the housing, a second pair 3 for fixing a lamp element 8; near the lower edge of the side walls of the housing, a third pair 4 as a stop for the lamp element 8. Alternatively, the stop may be arranged above the second pair of ribs 3, which further reduces shadowing.
[0009] Das Leuchtenelement 8 besteht aus zwei Teilen, die unterschiedliche Funktionen aufweisen und somit aus unterschiedlichem Material bestehen, aber einstückig miteinander verbunden sind, nämlich einem Reflektor 9 und einer Diffusorscheibe 10. Die einstückige Verbindung wird durch Coextrusion ermöglicht. The lighting element 8 consists of two parts that have different functions and thus consist of different materials, but are integrally connected to each other, namely a reflector 9 and a diffuser 10. The integral connection is made possible by coextrusion.
[0010] Der Reflektor 9 weist im Wesentlichen zwei Bereiche auf, einen oberen Bereich 11, der sich beidseits einer langgestreckten Öffnung für das Leuchtmittel erstreckt und kreis-oder kegelschnittförmig gewölbt ist, und einen unteren, ebenen Bereich 12, der gleichzeitig die zur Befestigung im Gehäuse 1 dienenden Seitenwände des Leuchtenelements 8 bildet. Der obere Bereich kann je nach der gewünschten Abstrahlcharakteristik auch eben ausgebildet sein. The reflector 9 has essentially two areas, an upper portion 11 which extends on both sides of an elongated opening for the lamp and is curved in a circle or conically, and a lower, planar portion 12, which at the same time for mounting in Housing 1 serving side walls of the lamp element 8 forms. The upper region may also be flat, depending on the desired emission characteristic.
[0011] Die Seitenwände 12 erstrecken sich nach oben über die Verbindungslinien mit dem oberen Bereich hinaus und besitzen an ihrem oberen Rand einen nach aussen vorspringenden Wulst oder Rand 13, der im zusammengesetzten Zustand über den Rippen 3 des Gehäuses einrastet. The side walls 12 extend upward beyond the connecting lines with the upper portion and have at its upper edge an outwardly projecting bead or edge 13 which engages in the assembled state over the ribs 3 of the housing.
[0012] Der untere Rand der Seitenwände 12 des Reflektors ist infolge der Coextrusion einstückig mit der Diffusorscheibe 10 verbunden. Die Diffusorscheibe ist im vorliegenden Ausführungsbeispiel eben. Sie kann aber je nach dem gewünschten Licht auch gewölbt oder linsenförmig ausgebildet sein. Die Diffusorscheibe erstreckt sich beidseitig über die Seitenwände 12 hinaus und bildet damit Vorsprünge, die an den Gehäuserippen 4 anliegen und die oberste Position des Leuchtenelements 8 definieren. The lower edge of the side walls 12 of the reflector is integrally connected to the diffuser disk 10 as a result of coextrusion. The diffuser disk is flat in the present embodiment. But it can also be curved or lenticular depending on the desired light. The diffuser disc extends on both sides beyond the side walls 12 and thus forms projections which bear against the housing ribs 4 and define the uppermost position of the lamp element 8.
[0013] Am oberen Rand des oberen Bereichs des Reflektors und am unteren Rand der Seitenwände sind Befestigungsschienen 14 angeformt, hinter denen jeweils eine längs verlaufende Nut 15 gebildet ist, in welche zusätzliche Elemente eingeschoben werden können. At the upper edge of the upper portion of the reflector and at the bottom of the side walls fastening rails 14 are formed, behind each of which a longitudinal groove 15 is formed, in which additional elements can be inserted.
