Description

Leuchtenelement und Leuchte  Luminaire element and luminaire
Die Erfindung betrifft ein Leuchtenelement und eine Leuchte gemäss dem Oberbegriff der Patentansprüche 1 und 6. Insbe¬ sondere betrifft die Erfindung eine Leuchte für ein stab- formiges, d. h. starres Leuchtmittel. The invention relates to a luminaire element and a luminaire according to the preamble of claims 1 and 6. In particular ¬ special, the invention relates to a luminaire for a rod-shaped, ie, rigid lighting means.
Leuchten für langgestreckte oder stabförmige Leuchtmittel oder längs angeordnete Punktlichtquellen, z.B. sog. Leucht¬ stoffröhren oder LEDs, besitzen in der Regel ein Gehäuse, in welchem evtl. Halterungen oder Leuchteneinsätze für die Sockel der Leuchtmittel, sowie für Elemente zum Beeinflus¬ sen des vom Leuchtmittel abgestrahlten Lichts vorgesehen sind. Diese im Rahmen dieser Beschreibung als Leuchtenele¬ mente 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 auf¬ gebracht ist. Für den Zweck dieser Beschreibung umfasst der Begriff „Reflektor" somit auch Leuchtenelemente, die das einfallende Licht diffus reflektieren. Eine Diffusorschei- be 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 dement- sprechenden Material aus verschiedenen stranggepressten Profilen oder abgekanteten, gerundeten oder anders umgeformten Blechen hergestellt und in das Leuchtengehäuse ein- gesetzt, wo sie mittels möglichst einfachen Verbindungsele¬ menten, 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. Lamps for elongate or rod-shaped light sources or longitudinally arranged point light sources, such as so-called. Luminous ¬ fluorescent tubes or LEDs, have of the lamps usually have a housing in which possibly supports or luminaire inserts to the base of lamps, as well as elements for Beeinflus ¬ sen radiated light are provided. 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 light source in the desired direction, for example of an opaque plastic material, on the inside of a reflective or scattering layer is ¬ brought. For the purposes of this description, the term "reflector" thus also encompasses luminaire elements which diffusely reflect the incident light A diffuser disk consists of a transparent or semi-transparent material, for example of acrylic glass or polycarbonate Depending on their function and their corresponding material, luminaire elements are manufactured from various extruded profiles or beveled, rounded or other shaped sheet metal and inserted into the luminaire housing. set where they by means of simple Verbindungsele ¬ elements, preferably by snapping 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.
Aus der WO 02/010640 AI ist beispielsweise eine Aperturlam¬ pe mit einem Aperturlampengehäuse bekannt, welches ver¬ schiedene Gehäusehülsen und Abdeckungen für die Hülsen zeigt. Die Hülsen dienen unterschiedlichen optischen und elektrischen Funktionen sind und hierfür z. B. metallisiert oder beschichtet. Die Lichtoptik besteht bei dieser From WO 02/010640 Al a Aperturlam ¬ pe with a Aperturlampengehäuse is known, for example, showing different ver ¬ housing sleeves and covers for the sleeves. The sleeves serve different optical and electrical functions and this z. B. metallized or coated. The light optics exists in this
Aperturlampe daher aus mehreren Elementen, die bei der Herstellung der Lampe einzeln zusammengesetzt oder in mehre- rern Prozessen erstellt werden. Aperture lamp therefore consists of several elements, which are assembled individually in the manufacture of the lamp or created in several processes.
Der Erfindung liegt die Aufgabe zugrunde, den Befestigungs¬ aufwand für Leuchtenelemente in einer Leuchte durch Verrin¬ gerung der Anzahl von Teilen zu verkleinern und gleichzei- tig die Leuchteneffizienz zu erhöhen. The invention is based on the objective to reduce the mounting ¬ expenses for lighting elements in a luminaire by Verrin ¬ delay the number of parts and at the same tig to increase the lighting efficiency.
Erfindungsgemäss wird dies erreicht durch ein Leuchtenele¬ ment und eine Leuchte, die sich durch die kennzeichnenden Merkmale der Patentansprüche 1 und 6 auszeichnen. This is achieved according to the invention by means of a luminaire element and a luminaire, which are distinguished by the characterizing features of patent claims 1 and 6.
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 ers- te Bereich und der zweite Bereich sind durch Coextrusion einstückig miteinander verbunden und bilden somit ein einstückiges coextrudiertes Profil. Die unterschiedlichen Be¬ reiche des Leuchtenelements können z. B. aus PMMA oder PC bestehen . Das Leuchtenelement weist eine Befestigung auf, mit der es in einfacher Weise in einem Gehäuse der Leuchte vorzugswei¬ se lösbar befestigt werden kann. Dabei kann ein Bereich des Leuchtenelements eine langgestreckte Öffnung für das Accordingly, the lighting element consists of at least a first region and at least a second region, wherein the first region and the second region are two functionally and materially different regions. The first region and the second region are integrally connected by coextrusion, thus forming a one-piece coextruded profile. The different Be ¬ rich of the lamp element can, for. B. PMMA or PC. The luminaire element has a fastening with which it can be attached in a simple manner in a housing of the lamp vorzugswei ¬ se releasably. In this case, a region of the lamp element can be an elongated opening for the
Leuchtmittel aufweisen, so dass das Leuchtmittel in dasHave light source, so that the light source in the
Leuchtenelement hineinragen und innerhalb des Leuchtenele¬ ments 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 Sei¬ tenwände innerhalb des Gehäuses sind. Die Seitenwände kön¬ nen beispielsweise von einem ersten Bereich, wie etwa einem Reflektorbereich, und der Basisbereich von einem zweiten Bereich, wie etwa einem Diffusorbereich, gebildet werden.Luminaire element protrude and can be stored within the Leuchtenele ¬ ment. The lighting element thus has an inner space enclosed by side walls and a base region connecting the lower parts of the side walls. The base area may, for. B. are covered with an open area of the housing, while the Sei ¬ tenwände are within the housing. The side walls Kgs ¬ NEN example, from a first region, such as a reflector region and the base region from a second region, such as a diffuser area can be formed.
In diesem Fall wird das Licht des Leuchtmittels an den Sei¬ tenwänden reflektiert und der Basisbereich diffus durchleuchtet . Die neuartige Geometrie ermöglicht eine Lichtreflexion am „Reflektor" und nicht mehr am grauen Alukörper, was eine wesentliche Verbesserung ohne zusätzliche Kosten bedeutet. In this case, the light of the bulb is reflected at the Be ¬ tenwänden and the base region is illuminated by diffuse. The novel geometry allows light reflection at the "reflector" instead of the gray aluminum body, which means a significant improvement at no extra cost.
Im Folgenden ist anhand der beiliegenden Zeichnung ein be- vorzugtes Ausführungsbeispiel der Erfindung beschrieben.In the following, a preferred embodiment of the invention is described with reference to the accompanying drawings.
Die Zeichnung zeigt einen Schnitt senkrecht zur Längsrichtung einer Leuchte für eine Leuchtstoffröhre. 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 ers¬ tes Paar 2 zur Befestigung eines Leuchteneinsatzes 5 für die erforderlichen Sockel 6 einer Leuchtstoffröhre 7; un- terhalb der Gehäusemitte ein zweites Paar 3 zur Befestigung eines Leuchtenelements 8; nahe beim unteren Rand der Sei¬ tenwände 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. On the two side walls, mutually opposite, inwardly projecting ribs are arranged as follows: slightly above the middle of the housing ers ¬ tes a pair 2 for fixing a lamp insert 5 for the required base 6 of a fluorescent tube 7; below the center of the housing a second pair 3 for attachment a lamp element 8; near the lower edge of the Sei ¬ tenwände of the housing, a third pair 4 as a stop for the lamp element 8. Alternatively, the stop can be arranged above the second pair of ribs 3, which further reduces shadowing.
Das Leuchtenelement 8 besteht aus zwei Teilen, die unter¬ schiedliche Funktionen aufweisen und somit aus unterschied¬ lichem Material bestehen, aber einstückig miteinander ver- bunden sind, nämlich einem Reflektor 9 und einer Diffusor- scheibe 10. Die einstückige Verbindung wird durch Coextru¬ sion ermöglicht. The glow element 8 consists of two parts which have different functions under ¬ and thus consist of different ¬ Lichem material but comparable integrally with each other are connected, namely a reflector 9 and a diffuser disc 10. The one-piece connection is Coextru ¬ sion allows.
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 bil- det. Der obere Bereich kann je nach der gewünschten Abstrahlcharakteristik auch eben ausgebildet sein. The reflector 9 has substantially two areas, an upper portion 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, planar portion 12, which at the same time serving for attachment in the housing 1 Side walls of the luminous element 8 forms det. The upper region may also be flat, depending on the desired emission characteristic.
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 upwardly 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.
Der untere Rand der Seitenwände 12 des Reflektors ist in- folge 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 Seiten- wände 12 hinaus und bildet damit Vorsprünge, die an den Ge- häuserippen 4 anliegen und die oberste Position des Leuchtenelements 8 definieren. Demnach kann die Diffusorscheibe die offene Seite des Gehäuses abdecken, so dass das Leuch¬ tenelement einen Teil des Gehäuses bilden kann. Das Leuch¬ tenelement ist abnehmbar, so dass das Leuchtmittel in ein¬ facher Weise ausgetauscht werden kann. The lower edge of the side walls 12 of the reflector is integrally connected to the diffuser disk 10 as a result of the 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 disk extends beyond the side walls 12 on both sides and thus forms projections which are in contact with the side walls 12. abut housing ribs 4 and define the uppermost position of the lamp element 8. Accordingly, the diffuser disc can cover the open side of the housing, so that the light ¬ tenelement can form part of the housing. The light ¬ tenelement is removable, so that the light source can be exchanged in a ¬ way.
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 eingescho¬ ben werden können. At the upper edge of the upper portion of the reflector and at the bottom of the side walls mounting rails 14 are formed, behind each of which a longitudinal groove 15 is formed, in which additional elements can be gescho ¬ ben.
