Fastened detachably on the inside of both longitudinal screen profiles (11) in each case is an angular reflector strip (16), whose angular edges (16a) are situated opposite one another, so that the limbs of the reflector strips (16) in each case form a reflector opening outwards. <IMAGE>

Description

Die Erfindung bezieht sich auf einen rohrförmigen Schirm aus einem stranggepreßten Metallrohr mit in dessen Längsrichtung verlaufender Öffnung und mit in das Metallrohr eingesetzten Reflektoren und/ oder IIalteeinrichtungen zur lösbaren Befestigung elektrischer Leuchtstoffröhren.The invention relates to a tubular screen made of an extruded metal tube with an opening running in the longitudinal direction thereof and with reflectors and / or IIalter devices inserted in the metal tube for the detachable fastening of electrical fluorescent tubes.

Bei derartigen bekannten rohrförmigen Schirmen stahlt die Leuchtstoffröhre einseitig durch die Längsöffnung, wobei Stahlen auf der Rückseite der Leuchtstoffröhre von einem die Leuchtstoffröhre abdeckenden Reflektor gerichtet durch die Längsöffnung geführt sind.In such known tubular umbrellas, the fluorescent tube steals through the longitudinal opening on one side, wherein steels on the back of the fluorescent tube are directed through the longitudinal opening by a reflector covering the fluorescent tube.

Aufgabe der Erfindung ist es, einen rohrförmigen Schirm der genannten Gattung dahingehend zu verbessern, daß die Stahlen der Leuchtstoffröhre nicht nur einseitig, sondern auch auf gegenüberliegenden Seiten aus dem Schirm mit optimaler Stahlenbündelung herausgeführt werden.The object of the invention is to improve a tubular screen of the type mentioned in such a way that the steels of the fluorescent tube are led out of the screen not only on one side but also on opposite sides with optimum bundling of steel.

Erfindungsgemäß wird die Aufgabe bei einem rohrförmigen Schirm dadurch gelöst, daß der Schirm auf zwei sich gegenüberliegenden Seiten mit Längsöffnungen für den Stahlenaustritt versehen ist, die durch zwei im Abstand voneinander angeordnete Schirmlängsprofile gebildet sind,, an denen innenseitig jeweils ein in sich abgewinkelter Reflektorstreifen befestigt ist, deren sich gegenüberliegende Schenkel jeweils einen nach außen sich öffnenden Reflektor bilden.According to the invention the object is achieved with a tubular screen in that the screen is provided on two opposite sides with longitudinal openings for the steel exit, which are formed by two spaced longitudinal screen profiles, to each of which an angled reflector strip is attached on the inside , whose opposite legs each form an outwardly opening reflector.

Ein derartiger mit zwei Längsöffnungen für den Austritt der Lichtstrahlen einer Leuchtstoffröhr ausgebildeter rohrförmiger Schirm zeigt den Vorteil, daß zur Ausleuchtung eines Raumes keine zusätzlichen zur Raumdecke gerichteten Leuchten angebracht werden müssen.Such a tubular screen designed with two longitudinal openings for the exit of the light rays of a fluorescent tube has the advantage that no additional lights directed towards the ceiling need to be attached to illuminate a room.

Ein weiter bevorzugtes Ausführungsbeispiel wird in der Formgebung und der Anordnung der Reflektorstreifen gesehen, bei denen jeweils die Scheitellinie der sich gegenüberliegenden Reflektorstreifen parallel zu der Längsachse der Leuchtstoffröhren übereinstimmend verläuft. Dabei werden die Lichtstrahlen besonders vorteilhaft in zwei entgegengesetzte Richtungen geleitet, so daß Lichtstrahlen optimal ausgenutzt werden.A further preferred embodiment is seen in the shape and arrangement of the reflector strips, in each of which the apex line of the opposing reflector strips runs parallel to the longitudinal axis of the fluorescent tubes. The light rays are guided particularly advantageously in two opposite directions, so that light rays are optimally used.

Die Reflektorstreifen können auch derart um 180° ggegeneinander versetzt angeordnet sein,daß die Lichtstrahlen dabei asymmetrisch zur Längsachse des Schirmes austreten.The reflector strips can also be arranged offset from one another by 180 ° such that the light rays emerge asymmetrically to the longitudinal axis of the screen.

Es liegt auch im Rahmen der Erfindung, daß die Leuchtstoffröhren gegenüber den Scheitellinien der sich gegenüberliegenden Reflektorstreifen versetzt angeordnet sind, so daß die Lichtstahlen in anderer Weise jeweils an den Längsöffnungen des Schirmes austreten. Die Strahlenintensität kann somit variabel gestaltet werden.It is also within the scope of the invention that the fluorescent tubes are arranged offset with respect to the apex lines of the opposing reflector strips, so that the light beams emerge in a different way from the longitudinal openings of the screen. The radiation intensity can thus be made variable.

Vorteilhafte und bevorzugte Weiterbildungen des Erfindungsgedankens sind den Unteransprüchen zu entnehmen. Der Schtz erstreckt sich nicht nur auf die Merkmale der einzelnen Ansprüche, sondern auch auf deren Kombination.Advantageous and preferred developments of the inventive concept can be found in the subclaims. The protection extends not only to the features of the individual claims, but also to their combination.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen;

  • Fig. 1 eine perspektivische Ansicht einer Hälfte des Schirmes mit Teilreflektor und Verankerungsschild;
  • Fig. 2 einen Querschnitt durch den Schirm mit Doppelreflektor.
In the drawing, an embodiment of the invention is shown. Show it;
  • Figure 1 is a perspective view of one half of the screen with partial reflector and anchor plate.
  • Fig. 2 shows a cross section through the screen with a double reflector.

Ein rohrförmiger Schirm 10 zur Aufnahme (Halterung) von Leuchtstoffröhren weist zwei sich gegenüberliegende spiegelbildlich gleiche Schirmlängsprofile 11 auf, die zwischen sich gegenüberliegende, zwei Durchtrittsöffnungen 12,13 für die von der leuchtstoffröhre 14 kommenden Stahlen freilassen.A tubular screen 10 for receiving (holding) fluorescent tubes has two opposite longitudinal mirror-image profiles 11 which are mirror images of one another and which leave two through openings 12, 13 between them for the steels coming from the fluorescent tube 14.

An jedem Schirmlängsprofil 11 sind mittels Nockenleisten 15 die Stirnkanten jeweils eines in sich abgewinkelten Reflektorstreifens 16 lösbar eingespannt, dessen Winkelscheitellinie 16a mit der parallel dazu verlaufenden gedachten Längsachse der Leuchtstoffröhre 14 übereinstimmt.The end edges of an angled reflector strip 16 are releasably clamped on each longitudinal screen profile 11 by means of cam strips 15, the angular apex line 16a of which coincides with the imaginary longitudinal axis of the fluorescent tube 14 running parallel thereto.

Die Leudtstoffröhre 14 erstreckt sich innerhalb des rohrförmigen Schirmes 10 exzentrisch, so daß dementsprechend der Reflektor 16 ungleichlange Schenkel aufweist, um die von der Leuchtstoffröhre 14 kommenden Strahlen optimal nach außen abzulenken (zu brechen). Der Winkel, den die beiden ungleichlangen Schenkel des Reflektors 16 miteinander bilden, liegt vorzugsweise über 900.The Leudtstoff tube 14 extends eccentrically within the tubular screen 10, so that accordingly the reflector 16 is unequal has long legs in order to optimally deflect (break) the rays coming from the fluorescent tube 14 outwards. The angle which the two unequal legs of the reflector 16 form with one another is preferably over 900 .

Die Durchtrittsöffnungen 12,13 sind zweckmäßig jeweils durch eine durchsichige, mehr oder weniger das Licht zerstreuende Abdeckplatten 17 verdeckt die auch die Aufgabe haben, ein Verstauben des Innenraumes des Schirms zu verhindern.The passage openings 12, 13 are expediently covered by a transparent, more or less light-diffusing cover plate 17, which also has the task of preventing the interior of the screen from becoming dusty.

Dazu sind diese Abdeckplatten 17 randseitig mit Rastnasen 18 ausgestattet, die hinter Nocken 19 an den Stirnkanten der Schirmlängsprofile 11 fassen und leicht zu lösen sind, um z.B. die Leuchtstoffröhre auszuwechseln oder die Reflektoren zu reinigen.For this purpose, these cover plates 17 are equipped on the edge with locking lugs 18, which are gripped behind cams 19 on the front edges of the longitudinal screen profiles 11 and are easy to release, e.g. replace the fluorescent tube or clean the reflectors.

Während die Schirmlängsprofile 11 vorzugsweise aus Leichtmetall gebildet sind, bestehen die Abdeckplatten 17 aus Kunststoff oder Glas,While the longitudinal screen profiles 11 are preferably made of light metal, the cover plates 17 consist of plastic or glass,

Die beiden Schirmlängsprofile 11, die getrennt voneinander verlaufen, sind mittels endseitigen Verankerungs- oder Halteschilden 2o zusammengehalten. Dazu stehen seitlich dieser Schilde 2o etwas elastisch ausgebildete Haltenasen 21 vor, die hinter Halteleisten 22 fassen, die/im Bereich der Nockenleisten 15 in den Schirminnenraum vorstehen. Diese Verankerungs- oder Halteschilde 2o können durch gesonderte gewölbte Abdeckplättchen, welche sich an die Abdeckplatten 17 endseitig anschließen, nach außen verdeckt sein (nicht dargestellt).The two longitudinal screen profiles 11, which run separately from one another, are held together by means of end-side anchoring or holding plates 20. To this end, there are somewhat elastic retaining lugs 21 protruding to the side of these shields 2o, which hold behind retaining strips 22 which protrude / into the area of the cam strips 15 into the interior of the shield. These anchoring or holding shields 20 can be concealed from the outside by separate curved cover plates which adjoin the end of the cover plates 17 (not shown).

Zur günstigen Raumausnutzung können endseitig jedes Schirmes 10 zwei Verankerungs- oder Halteschilde 2o angeordnet sein, welche die Kondensatoren 23 und sonstigen Anschluß- und/oder Schalteinrichtungen 24 für die Leuchtstoffröhren 14 zwischen sich an einer Halteplatte 25 tragen.For favorable use of space, two anchoring or holding shields 20 can be arranged at the end of each screen 10, which carry the capacitors 23 and other connection and / or switching devices 24 for the fluorescent tubes 14 between them on a holding plate 25.

Gegen eine Längsverschiehung dieser Schilde 20 sichern die Stirnkanten der seitlichen Reflektorstreifen 16 die entsprechend kürzer sind als die Länge des Gesamtschirms und damit endseitig verbreiterten Raum zur Anlage der vorgenannten Schilde 2o mit Halteplatte 25 usw. begrenzen.The front edges of the lateral reflector strips 16, which are correspondingly shorter than the length of the overall screen and thus end-widened space for the abovementioned shields 2o with holding plate 25, etc., protect against a longitudinal displacement of these shields 20.

Zur Verstärkung der Schirmlängsprofile 11 und zur Abstützung der Reflektorstreifen 16 stehen schmale Rippen 26 und 27 in den Schiminnenraum vor, die an der Innenseite der Schirmlängsprofile 11 angeformt sind. Da diese Rippen 26,27 sich vorzugsweise über die ganze Länge der Schirmlängsprofile 11 erstrecken, so sind die Schilde 2o denentsprechend seitlich konturmäßig geformt.To reinforce the longitudinal screen profiles 11 and to support the reflector strips 16, narrow ribs 26 and 27 protrude into the interior of the chimney, which are integrally formed on the inside of the longitudinal screen profiles 11. Since these ribs 26, 27 preferably extend over the entire length of the longitudinal screen profiles 11, the shields 20 are accordingly contoured laterally.

Die Nockenleisten 15 und Halteleisten 22 lassen einen im Querschnitt abgerundeten Raum 28 frei, so daß darin Verbindungsschrauben (nicht dargestell) einfassen können, die sich in Längsrichtung des Schirmes erstrecken, Die durch die Rippen 26,27 abgegrenzten Räume können als Kabelkanäle dienen.The cam strips 15 and holding strips 22 leave a space 28 with a rounded cross-section free, so that connecting screws (not shown) can extend therein, which extend in the longitudinal direction of the screen, The spaces delimited by the ribs 26, 27 can serve as cable ducts.

Die Reflektorstreifen 16 erstrecken sich gemäß Fig. 2 beispielsweise symmetrisch zur Mittelebene. Sie können jedoch auch im 180° verdreht (einer gegenüber dem anderen) eingesetzt sein, so daß die Lichtstrahlen asymmetrisch aus den Längsöffnungen 12,13 austreten. Dazu sind dann die Rippen 26 und 27 in ihrer Länge zu verändern. Asymmetrische Lichtstrahlenaustritte können auch durch Verlagerung der Leuchtröhre 14 innerhalb des Schirmes erzielt werden.2, for example, the reflector strips 16 extend symmetrically to the center plane. However, they can also be rotated through 180 ° (one relative to the other), so that the light rays emerge asymmetrically from the longitudinal openings 12, 13. The ribs 26 and 27 are then to be changed in length. Asymmetrical light beam exits can also be achieved by moving the fluorescent tube 14 within the screen.

Die Längsprofile 11 lassen sich auch durch andere Haltemittel zusammenhalten, beispielsweise durch Verschraubung mit Endkappen.The longitudinal profiles 11 can also be held together by other holding means, for example by screwing with end caps.
