Description

Die Erfindung betrifft ein Leuchtenelement und eine Leuchte gemäss dem Oberbegriff der Patentansprüche 1 und 4. Insbesondere betrifft die Erfindung eine Leuchte für ein langgestrecktes oder stabförmiges, d. h. starres Leuchtmittel.The invention relates to a lamp element and a lamp according to the preamble of claims 1 and 4. In particular, the invention relates to a lamp for an elongated or rod-shaped, ie. H. rigid lamp.

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. Gemäss dem Stand der Technik werden die unterschiedlichen Leuchtenelemente je nach ihrer Funktion und ihrem dementsprechenden 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.Luminaires for elongated or rod-shaped illuminants or longitudinally arranged point light sources, e.g. so-called fluorescent tubes or LEDs, generally have a housing in which holders or luminaire inserts for the base of the illuminants, as well as for elements for influencing the light emitted by the illuminant, are provided . These parts, which are referred to as luminaire elements in 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. There is a reflector which is intended to direct the light emitted by the illuminant in the desired direction, for example from an opaque plastic material, on the inside of which a reflective or scattering layer is applied. For the purpose of this description, the term "reflector" therefore also includes lighting elements which diffusely reflect the incident light. A diffuser disc consists of a transparent or semi-transparent material, such as acrylic glass or polycarbonate. According to the state of the art, depending on their function and their corresponding material, the different luminaire elements are manufactured from different extruded profiles or bent, rounded or other shaped sheets and inserted into the luminaire housing. where they are held by means of connecting elements which are as simple as possible, preferably by engaging grooves and the like on ribs and the like. Holding means are therefore required for each luminaire element of a luminaire, which requires design effort.

Aus der WO 02/10640 A1 ist beispielsweise eine Aperturlampe mit einem Aperturlampengehäuse bekannt, welches verschiedene Gehäusehülsen und Abdeckungen für die Hülsen zeigt. Die Hülsen dienen unterschiedlichen optischen und elektrischen Funktionen und sind hierfür z. B. metallisiert oder beschichtet. Die Lichtoptik besteht bei dieser Aperturlampe daher aus mehreren Elementen, die bei der Herstellung der Lampe einzeln zusammengesetzt oder in mehrerern Prozessen erstellt werden.From the WO 02/10640 A1 For example, an aperture lamp with an aperture lamp housing is known, which shows various housing sleeves and covers for the sleeves. The sleeves serve different optical and electrical functions and are z. B. metallized or coated. The light optics in this aperture lamp therefore consist of several elements, which are assembled individually during the manufacture of the lamp or created in several processes.

In der US 2004/042225 A1 ist dagegen eine Leuchtenanordnung für ein Fahrzeug gezeigt, bei dem ein Leuchtmittel in einem Gehäuse mit unterschiedlichen optischen Bereichen eingeschlossen ist, so dass Leuchtmittel und Gehäuse eine Einheit bilden. Die Einheit kann als Ganzes an einer Decke eines Fahrzeugs montiert werden.In the US 2004/042225 A1 on the other hand, a lamp arrangement for a vehicle is shown, in which a lamp is enclosed in a housing with different optical areas, so that the lamp and housing form a unit. The unit can be mounted as a whole on a ceiling of a vehicle.

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 mounting effort for lamp elements in a lamp by reducing the number of parts and at the same time to increase the lamp efficiency.

Erfindungsgemäss wird dies erreicht durch ein Leuchtenelement und eine Leuchte, die sich durch die kennzeichnenden Merkmale der Patentansprüche 1 und 4 auszeichnen.According to the invention this is achieved by a lamp element and a lamp which are characterized by the characterizing features of claims 1 and 4.

Demnach besteht das Leuchtenelement aus wenigstens einem ersten Bereich und wenigstens einem zweiten Bereich, wobei der erste Bereich und der zweite Bereich zwei funktional und materialmässig unterschiedliche Bereiche sind. Der erste Bereich und der zweite Bereich sind durch Coextrusion einstückig miteinander verbunden und bilden somit ein einstückiges coextrudiertes Profil. Die unterschiedlichen Bereiche des Leuchtenelements können z. B. aus PMMA oder PC bestehen.Accordingly, the luminaire element consists of at least a first area and at least a second area, the first area and the second area being two functionally and materially different areas. The first area and the second area are integrally connected to one another by coextrusion and thus form a one-piece coextruded profile. The different areas of the lamp element can e.g. B. consist of PMMA or PC.

Das Leuchtenelement weist eine Befestigung auf, mit der es in einfacher Weise in einem Gehäuse der Leuchte lösbar befestigt werden kann. Dabei weist ein Bereich des Leuchtenelements eine langgestreckte Öffnung für das Leuchtmittel auf, so dass das Leuchtmittel in das Leuchtenelement hineinragen und innerhalb des Leuchtenelements gelagert werden kann. Das Leuchtenelement weist somit einen inneren Raum auf, der durch Seitenwände und einen die unteren Teile der Seitenwände verbindenden Basisbereich eingefasst ist. Der Basisbereich kann z. B. mit einen offenen Bereich des Gehäuses abgedeckt werden, während die Seitenwände innerhalb des Gehäuses sind. Die Seitenwände können beispielsweise von einem ersten Bereich, wie etwa einem Reflektorbereich, und der Basisbereich von einem zweiten Bereich, wie etwa einem Diffusorbereich, gebildet werden. In diesem Fall wird das Licht des Leuchtmittels an den Seitenwänden reflektiert und der Basisbereich diffus durchleuchtet.The lamp element has a fastening with which it can be detachably fastened in a simple manner in a housing of the lamp. A region of the lamp element has an elongated opening for the lamp, so that the lamp protrudes into the lamp element and can be stored within the lamp element. The lamp element thus has an inner space, which is bordered by side walls and a base region connecting the lower parts of the side walls. The base area can e.g. B. be covered with an open area of the housing while the side walls are inside the housing. The side walls can be formed, for example, by a first region, such as a reflector region, and the base region by a second region, such as a diffuser region. In this case, the light from the illuminant is reflected on the side walls and the base area is diffusely illuminated.

Die neuartige Geometrie ermöglicht eine Lichtreflexion am "Reflektor" und nicht mehr am grauen Alukörper, was eine wesentliche Verbesserung ohne zusätzliche Kosten bedeutet. 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.The new geometry enables a light reflection on the "reflector" and no longer on the gray aluminum body, which means a significant improvement without additional costs. A preferred exemplary embodiment of the invention is described below with reference to the accompanying drawing. The drawing shows a section perpendicular to the longitudinal direction of a lamp for a fluorescent tube.

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 cross section open at the bottom. On 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 fastening a lamp insert 5 for the required base 6 of a fluorescent tube 7; a second pair 3 for fastening below the middle of the housing 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 can also be arranged above the second pair of ribs 3, which further reduces the formation of shadows.

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 lamp element 8 consists of two parts, which have different functions and thus consist of different materials, but are integrally connected to one another, namely a reflector 9 and a diffuser disc 10. The one-piece connection is made possible by coextrusion.

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 essentially has two areas, an upper area 11, which extends on both sides of an elongated opening for the lamp and is curved in a circular or conical shape, and a lower, flat area 12, which at the same time serves for fastening in the housing 1 Forms side walls of the lamp element 8. Depending on the desired radiation pattern, the upper area can also be flat.

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 region and have at their upper edge an outwardly projecting bead or edge 13 which, in the assembled state, engages over the ribs 3 of the housing.

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. Demnach kann die Diffusorscheibe die offene Seite des Gehäuses abdecken, so dass das Leuchtenelement einen Teil des Gehäuses bilden kann. Das Leuchtenelement ist abnehmbar, so dass das Leuchtmittel in einfacher Weise ausgetauscht werden kann.The lower edge of the side walls 12 of the reflector is integrally connected to the diffuser disc 10 due to the coextrusion. The diffuser disc is flat in the present exemplary embodiment. However, depending on the desired light, it can also be curved or lenticular. The diffuser disc extends on both sides beyond the side walls 12 and thus forms projections on the housing ribs 4 rest and define the top position of the lamp element 8. Accordingly, the diffuser disc can cover the open side of the housing, so that the lamp element can form part of the housing. The lamp element is removable, so that the lamp can be easily replaced.

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.Fastening rails 14 are formed on the upper edge of the upper region of the reflector and on the lower edge of the side walls, behind which a longitudinal groove 15 is formed, into which additional elements can be inserted.
