Die Erfindung h trifft eine Leuchte mit den im Oberbegriff des Schutzanspruchs 1 angegebenen Merkmalen.The invention relates to a luminaire with the features specified in the preamble of claim 1.
Derartige Leuchten, bei welchen sich die Leuchtstoffröhre in einem zumindest im Bereich des Lichtaustritts transparenten Rohr befindet, werden als Deckenleuchten, Handleuchten (vgl. DE-GM 85 10 777) und auch als Maschinenleuchten verwendet.Such luminaires, in which the fluorescent tube is located in a tube that is transparent at least in the area of the light exit, are used as ceiling lights, hand lamps (cf. DE-GM 85 10 777) and also as machine lights.
Problematisch bei Leuchten mit rohrförmigem Gehäuse ist die Anbringung eines Blendschutzraeters, das aber immer dann erforderlich ist, wenn der Arbeitsplatz blendfrei und gerichtet beleuchtet werden soll.The problem with lamps with tubular housings is the installation of an anti-glare device, which is always necessary if the workplace is to be illuminated glare-free and directed.
Bei an der Decke zu montierenden Raumleuchten ist es bekannt, im Lichtaustrittsbereich das etwa halbschalenförmig ausgebildete Blendschutzraster einzusetzen. Die Konstruktion einer derartigen Leuchte ist noch vergleichsweise aufwendig. Außerdem sind die Rippen des Blendschutzrasters von außenFor room lights that are to be mounted on the ceiling, it is common to use a half-shell-shaped anti-glare grid in the light emission area. The construction of such a light is still relatively complex. In addition, the ribs of the anti-glare grid are

zugänglich/ so daß sie verschmutzt oder gar beschädigt werden können. Für Hand- oder Arbeitsplatzleuchten ist eine derartige Montage des Blendschutzraster unzweckmäßig.accessible/ so that they can become dirty or even damaged. For hand or work lights, this type of installation of the anti-glare grille is not practical.
Der vorliegenden Erfindung lie^t darum die Aufgabe zugrunde, für eine Leuchte der im Oberbegriff angegebenen Art eine Blendschutzrasteranordnung zu schaffen, die mit geringem Fertigungsaufwand, also kostengünstig, montiert werden kann und außerdem gegen Verschmutzung und mechanisch« Beschädigung besser gesichert ist. Soweit, wie gemäß Anspruch 2 vorausgesetzt ist, das rohrförmige Gehäuse vollständig aus transparentem Material besteht, wird vorgeschlagen, den Bereich außerhalb des Blendschutzrasters mit einem Reflektor abzudecken, der sich über die gesamte Länge der Leuchtstoffröhre erstreckt.The present invention is therefore based on the object of creating an anti-glare grid arrangement for a lamp of the type specified in the preamble, which can be assembled with little manufacturing effort, i.e. inexpensively, and is also better protected against dirt and mechanical damage. Insofar as, as is assumed according to claim 2, the tubular housing consists entirely of transparent material, it is proposed to cover the area outside the anti-glare grid with a reflector that extends over the entire length of the fluorescent tube.
An sich bekannte konstruktive Einzelheiten eines derartigen Reflektors sind Gegenstand des Anspruchs 3.Known structural details of such a reflector are the subject of claim 3.
Des an der Innenseite des rohrförmigen Gehäuse anliegende Blendschutzraster kann gemäß Anspruch 4 aus achsparallel und senkrecht zu diesen verlaufenden Rippen bestehen, die zur Verbesserung des Blendschutzes bei optimaler Licht "ausbaute parabolischen Querschnitt haben, wie dies bei ebenen Blendschutzrastern bekannt ist. Deren Oberfläche kann nach dem Vorschlag gemäß Anspruch 6 verspiegelt sein, wobei die Verspiegelung bei aus Kunststoff-Spritzguß (Anspruch 5) bestehenden Rastern gemäß Anspruch 7 aufgedampft ist. The anti-glare grid on the inside of the tubular housing can, according to claim 4, consist of ribs running parallel to the axis and perpendicular to these, which have a parabolic cross-section to improve the glare protection with optimal light, as is known for flat anti-glare grids. Their surface can be mirrored according to the proposal according to claim 6, the mirroring being vapor-deposited in the case of grids made of plastic injection molding (claim 5) according to claim 7.
Als Material für das rohrförmige Gehäuse eignet sich gemäß Anspruch 2 sowohl keramisches Glas, also im wesentlichen aus Mineraloxyden bestehendes Glas, und polymeres Glas, also aus transparentem Kunststoff bestehendes Glas, wie Acrylglas.According to claim 2, both ceramic glass, i.e. glass consisting essentially of mineral oxides, and polymer glass, i.e. glass consisting of transparent plastic, such as acrylic glass, are suitable as materials for the tubular housing.
Reflektor und Blendschutzraster können sowohl aus Kunststoff als auch aus metallischen Materialien, wie Aluminium- oder Stahlblech, bestehen.The reflector and anti-glare grille can be made of plastic or metallic materials such as aluminum or sheet steel.
Je nach Größe und erforderlicher Lichtstärke kann die Leuchte mit einer konzentrisch, oder mehreren parallel zueinander ausgerichteten Leuchtstoffröhren ausgestattet sein. Eine Leuchte mit zwei symmetrisch zur Mittellinie angeordneten Leuchtstoffröhren ist Gegenstand des Anspruchs 8.Depending on the size and required light intensity, the lamp can be equipped with one concentric fluorescent tube or several fluorescent tubes aligned parallel to one another. A lamp with two fluorescent tubes arranged symmetrically to the center line is the subject of claim 8.
Stattdessen kann gemäß Anspruch 9 auch eine sogenannte. U-förmig geformte Kompaktleuchtstoffröhre verwendet werden.Instead, according to claim 9, a so-called U-shaped compact fluorescent tube can also be used.
Konstruktive Details sind nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles im einzelnen erläutert. In der Zeichnung zeigenConstruction details are explained in detail below using an example shown in the drawing. The drawing shows

auf der das Blendschutzraster aufweisenden Seite undon the side with the anti-glare grille and
Figur 2 - Schnitt längs der Linie II-II in Figur 1.Figure 2 - Section along line II-II in Figure 1.
Die erfindungsgemäße Leuchte besteht aus einem Rohr 10 aus transparentem Material, welches die Leuchtstoffröhren 11, den Reflektor 12 und das Blendschutzraster 20 vollständig umschließt. Beidendig ist das Rohr mit Deckeln abgeschlossen, deren Dichtungsring 17 erforderlichenfalls Druckwasserdichtheit gewährleistet.The lamp according to the invention consists of a tube 10 made of transparent material, which completely encloses the fluorescent tubes 11, the reflector 12 and the anti-glare grid 20. The tube is closed at both ends with covers, the sealing ring 17 of which ensures water pressure tightness if necessary.
Bei dem dargestellten Ausführungsbeispiel sind zwei Leuchtstoffröhren 11 symmetrisch zur Mittelebene 0-0 achsparallelIn the embodiment shown, two fluorescent tubes 11 are symmetrical to the center plane 0-0 and parallel to the axis
verlaufend angeordnet. Sie werden beidseitig von Fassungen 18 gehaltert, welche ihrerseits an einem Fassungsträger 13 angeschraubt sind. Dieser Fassungsträger ist mit Hilfe von Schrauben 15 mit einer Stütze 14 verbunden, deren Stützblech 14a an der Innenseite des Reflektorbleches 12 anliegt. Das Reflektorblech 12 ist aus einem im Querschnitt polygonal verformten Blechstreifen hergestellt, der sich aufgrund Eigenspannung mit seinen Biegekanten 12a und seinen RandflÄ-chen 12b an der Innnenseite des Gehäuserohres 10 anlegt.arranged in a running pattern. They are held on both sides by sockets 18, which in turn are screwed to a socket carrier 13. This socket carrier is connected to a support 14 by means of screws 15, the support plate 14a of which rests on the inside of the reflector plate 12. The reflector plate 12 is made from a sheet metal strip with a polygonal cross-section, which, due to its inherent stress, rests with its bending edges 12a and its edge surfaces 12b on the inside of the housing tube 10.
An das Reflektorblech 12 anschließend ist im Bereich des Lichtaustrittes das Blendschutzraster 20 eingesetzt, deren achsparallel verlaufende Rippen 21 und senkrecht zu diesen verlaufenden Rippen 22 sich von den Leuchtstoffröhren 11 bzw. den seitlichen Rändern des Reflektors 11 bis zur Innenseite des Gehäuserohres 10 erstrecken. Die seitlichen Rippen 21' bilden mit dem Gehäuserohr 10 in Richtung auf den Reflektor 12 offene Schlitze, in welche das Reflektorblech 12 mit seinen Randflächen 12b eingesetzt ist.The anti-glare grid 20 is inserted adjacent to the reflector plate 12 in the area of the light exit, the ribs 21 of which run parallel to the axis and the ribs 22 running perpendicular to these extend from the fluorescent tubes 11 or the side edges of the reflector 11 to the inside of the housing tube 10. The side ribs 21' form open slots with the housing tube 10 in the direction of the reflector 12, into which the reflector plate 12 is inserted with its edge surfaces 12b.
Wie der Schnitt in Figur 2 aber auch die Aufsicht in Figur i deutlich machen, sind die Rippen 21 und 22 im Querschnitt derart parabolisch geformt, daß die breiteren Fußteile der Lichtquelle, also den Leuchtstoffröhren, zugewandt ist und die Rippen sich in Lichtaustrittsrichtung verjüngen.As the section in Figure 2 and the top view in Figure 1 make clear, the ribs 21 and 22 are parabolically shaped in cross-section so that the wider base parts face the light source, i.e. the fluorescent tubes, and the ribs taper in the direction of the light exit.
