Abstract

1. A lighting fitting for a tubular fluorescent lamp which comprises a housing and a trough-shaped mirror system arranged therein and which consists of a top mirror secured above the lamp in the housing and of two side mirrors, the side mirrors, together with cross bars which connect them, form an insert which is detachably held in the housing, characterized by at least two carriers (4) for holding the top mirror (3), which are fastened on the base (11) of the housing (1) and extend transversely to the longitudinal axis of the housing, each of said carriers having two abutment surfaces (41) for the edge strips (211) of the side mirrors (21) across which the insert (2), which is centrally secured in the housing (1) only at its front ends, is led.

Description

Die Erfindung betrifft eine Leuchte für eine stabförmige Leuchtstofflampe mit einem Gehäuse und einem darin angeordneten, rinnenförmigen Spiegelsystem, das aus einem oberhalb der Lampe befestigten Dachspiegel und zwei Seitenspiegeln besteht, wobei die Seitenspiegel mit sie verbindenden Querlamellen einen lösbar in dem Gehäuse gehalterten Einsatz bilden.The invention relates to a luminaire for a rod-shaped fluorescent lamp with a housing and a gutter-shaped mirror system arranged therein, which consists of a roof mirror attached above the lamp and two side mirrors, the side mirrors with cross blades connecting them forming an insert which is detachably held in the housing.

Bisher erforderte eine derartige, beispielsweise aus dem DE-U 1971019 bekannte Leuchte einen verhältnismässig hohen Aufwand für Aufbau und Halterung des Spiegeleinsatzes sowie des Dachspiegels. Dem Einsatz wurde in der Regel durch hochreichende Querlamellen und profilierte Rahmen eine hohe Eigensteifigkeit gegeben; zur Halterung im Gehäuse waren vier lösbare Verbindungen erforderlich.Until now, such a lamp, known for example from DE-U 1971019, required a relatively high outlay for the construction and mounting of the mirror insert and of the roof mirror. The use was generally given a high degree of inherent rigidity through the use of high-reaching transverse slats and profiled frames; four detachable connections were required for mounting in the housing.

Der Erfindung liegt die Aufgabe zugrunde, den konstruktiven Aufwand für eine Leuchte der eingangs genannten Art zu reduzieren; insbesondere soll die Verwendung eines Spiegeleinsatzes mit geringerer Eigensteifigkeit möglich sein.The invention has for its object to reduce the design effort for a lamp of the type mentioned; in particular, the use of a mirror insert with less inherent rigidity should be possible.

Die erfindungsgemässe Lösung dieser Aufgabe ist bei einer Leuchte der eingangs genannten Art gekennzeichnet durch mindestens zwei am Boden des Gehäuses befestigte, quer zur Längsachse des Gehäuses verlaufende Träger zur Halterung des Dachspiegels, die jeweils zwei Anschlagflächen für die Randstreifen der Seitenspiegel aufweisen, durch die der nur an seinen stirnseitigen Enden mittig in dem Gehäuse befestigte Einsatz geführt ist.The inventive solution to this problem is characterized in a lamp of the type mentioned by at least two fixed to the bottom of the housing, transverse to the longitudinal axis of the housing support for holding the roof mirror, each having two stop surfaces for the edge strips of the side mirror, by which the only at its front ends, the insert is guided centrally in the housing.

Die Erfindung kommt mit einem Spiegeleinsatz mit sehr geringer Eigensteifigkeit aus. Sie ermöglicht die Verwendung sehr dünnen Materials und den Verzicht auf versteifende Rahmen. Es genügt, die beiden Seitenspiegel lediglich durch die Querlamellen miteinander zu verbinden, die ihrerseits nur eine Höhe von 114 bis % der Höhe der Seitenspiegel aufzuweisen brauchen; dies kommt wiederum dem Leuchtenwirkungsgrad zugute, da hohe Querlamellen zu unnötigen Mehrfachreflexionen führen.The invention manages with a mirror insert with very little inherent rigidity. It enables the use of very thin materials and no stiffening frames. It is sufficient to connect the two side mirrors to one another only by means of the transverse slats, which in turn need only be 1 1 4 to% of the height of the side mirrors; this in turn benefits the efficiency of the luminaire, since high cross slats lead to unnecessary multiple reflections.

Die Anschlagflächen im Träger und die damit zusammenwirkenden Randstreifen der Seitenspiegel können vertikal oder - wie beim Ausführungsbeispiel - horizontal verlaufen. In jedem Fall wird ein Kippen des Spiegeleinsatzes um die beiden stirnseitigen Lagerpunkte vermieden und eine einwandfreie Ausrichtung innerhalb des Gehäuses gewährleistet.The stop surfaces in the carrier and the edge strips of the side mirrors interacting therewith can run vertically or - as in the exemplary embodiment - horizontally. In any case, tilting of the mirror insert around the two front bearing points is avoided and proper alignment within the housing is guaranteed.

Die stirnseitige Halterung des Spiegeleinsatzes hat den zusätzlichen Vorteil, dass sie auch dann noch brauchbar ist, wenn eine Lagerung des Spiegeleinsatzes an den Längsseiten des Gehäuses wegen zu grosser Höhe des Spiegeleinsatzes im Vergleich zur Lichtaustrittsöffnung nicht mehr möglich ist.The front-side mounting of the mirror insert has the additional advantage that it can still be used if storage of the mirror insert on the long sides of the housing is no longer possible due to the height of the mirror insert being too great compared to the light exit opening.

Weitere vorteilhafte Merkmale sind in den Unteransprüchen gekennzeichnet.Further advantageous features are characterized in the subclaims.

Ein Ausführungsbeispiel der Erfindung wird anhand der Figuren erläutert; es zeigen

  • Fig. 1 einen Querschnitt durch eine Leuchte entlang Linie I-I in Fig. 2,
  • Fig. 2 einen Längsschnitt durch das Gehäuse entlang Linie 11-11 in Fig. 1, und
  • Fig. 3 eine Draufsicht in Richtung des Pfeiles 111 in Fig. 2 auf einen Verschluss.
An embodiment of the invention is explained with reference to the figures; show it
  • 1 shows a cross section through a lamp along line II in FIG. 2,
  • Fig. 2 shows a longitudinal section through the housing along line 11-11 in Fig. 1, and
  • Fig. 3 is a plan view in the direction of arrow 111 in Fig. 2 of a closure.

Das im Querschnitt (Fig. 1) und im Längsschnitt (Fig. 2) rechteckige Gehäuse 1 weist einen ebenen Boden 11, ebene Stirnwände 12 und eine Lichtaustrittsöffnung auf; in der Lichtaustrittsöffnung ist ein Spiegeleinsatz 2 angeordnet, der aus zwei parabolisch gekrümmten Seitenspiegeln 21 und diese miteinander verbindenden, V-förmigen Querlamellen 22 besteht. Die Lage der Lampe 7 ist in den Figuren gestrichelt angedeutet. Die Querlamellen 22 erstrecken sich nicht höher, als es mit Rücksicht auf eine ausreichende Blendungsbegrenzung erforderlich ist; der sich oberhalb der Querlamellen erstreckende Abschnitt der Seitenspiegel ist dementsprechend mehr als doppelt so lang, wie die Höhe der Querlamellen. Bei Verwendung eines dünnen Spiegelmaterials (0,2 mm) und bei Verzicht auf einen zusätzlichen, in der Lichtaustrittsöffnung liegenden Rahmen für den Spiegeleinsatz 2, resultiert daraus eine sehr geringe Eigensteifigkeit des Spiegeleinsatzes.The housing 1, which is rectangular in cross section (FIG. 1) and in longitudinal section (FIG. 2), has a flat bottom 11, flat end walls 12 and a light outlet opening; In the light exit opening, a mirror insert 2 is arranged, which consists of two parabolically curved side mirrors 21 and V-shaped transverse slats 22 connecting them to one another. The position of the lamp 7 is indicated by dashed lines in the figures. The cross blades 22 do not extend higher than is necessary in view of a sufficient glare limitation; the section of the side mirrors extending above the transverse slats is accordingly more than twice as long as the height of the transverse slats. If a thin mirror material (0.2 mm) is used and there is no additional frame for the mirror insert 2 in the light exit opening, this results in a very low inherent rigidity of the mirror insert.

Zur zusätzlichen Führung und Ausrichtung des Spiegeleinsatzes 2 sind daher mindestens zwei Träger 4 vorgesehen, die im Abstand voneinander am Boden 11 des Gehäuses 1 befestigt sind. Es handelt sich dabei um Kunststofformteile, die auf ihrer Rückseite hakenförmige Füsse 45 aufweisen, die federnd durch Aussparungen im Boden 11 hindurchgreifen, so dass die Träger durch einfaches Einsprengen anzubringen sind. Diese quer zur Längsachse des Gehäuses verlaufenden Träger 4 weisen an ihren beiden äusseren Enden jeweils eine horizontal verlaufende Anschlagfläche 41 auf, an der ein abgewinkelter Randstreifen 211 jedes Seitenspiegels 21 bei in das Gehäuse 1 eingesetztem Spiegeleinsatz 2 anliegt. Die Abmessungen sind dabei so aufeinander abgestimmt, dass bei Anlage der Randstreifen 211 an den Anschlagflächen 41 der Spiegeleinsatz 2 in Bezug auf die Lichtaustrittsöffnung ausgerichtet ist. Zur Halterung des Spiegeleinsatzes 2 in dem Gehäuse 1 genügt daher je ein Verschluss 6, der mittig an der Innenseite jeder Stirnwand 12 des Gehäuses angebracht ist. Jeder Verschluss 6 besteht aus einem Federarm 61 mit einer Schulter 611 (Fig. 2), auf der sich der abgewinkelte Rand der letzten, halbierten Querlamelle 221 abstützt. Bei eingesetztem Spiegeleinsatz 2 sind somit die Verschlüsse 6 durch die halbierten Querlamellen 221 praktisch völlig verdeckt. Zum Herausnehmen des Spiegeleinsatzes 2 wird der Federarm 61 gegen die Stirnwand 12 gedrückt, wodurch der abgewinkelte Rand der letzten Lamelle 221 freigegeben wird. Ein Kippen des Spiegeleinsatzes 2 um die Schulter 611 der Verschlüsse 6 wird durch den Träger 4 mit seinen Anschlagflächen 41 verhindert.For additional guidance and alignment of the mirror insert 2, at least two supports 4 are therefore provided, which are fastened at a distance from one another on the bottom 11 of the housing 1. These are plastic molded parts which have hook-shaped feet 45 on their rear side, which extend resiliently through recesses in the base 11, so that the supports can be attached by simply snapging them on. These brackets 4, which run transversely to the longitudinal axis of the housing, each have at their two outer ends a horizontally running stop surface 41 against which an angled edge strip 211 of each side mirror 21 rests when the mirror insert 2 is inserted into the housing 1. The dimensions are matched to one another such that when the edge strips 211 bear against the stop surfaces 41, the mirror insert 2 is aligned with respect to the light exit opening. To hold the mirror insert 2 in the housing 1, one closure 6 is therefore sufficient, which is attached centrally to the inside of each end wall 12 of the housing. Each closure 6 consists of a spring arm 61 with a shoulder 611 (FIG. 2) on which the angled edge of the last, halved transverse lamella 221 is supported. When the mirror insert 2 is inserted, the closures 6 are thus practically completely covered by the halved transverse slats 221. To remove the mirror insert 2, the spring arm 61 is pressed against the end wall 12, whereby the angled edge of the last lamella 221 is released. The mirror insert 2 is tilted around the shoulder 611 of the closures 6 by prevents the carrier 4 with its stop surfaces 41.

Die stirnseitige Halterung des Spiegeleinsatzes 2 bedeutet eine Schwenkbewegung um eine Querachse des Spiegeleinsatzes beim Herausnehmen aus dem Gehäuse. Eine solche Schwenkbewegung ist auch bei sehr grosser Höhe des Spiegeleinsatzes und geringer Breite der Lichtaustrittsöffnung noch möglich, wenn die sonst übliche Lagerung des Spiegeleinsatzes entlang einer Längskante des Gehäuses nicht mehr durchführbar ist.The front mounting of the mirror insert 2 means a pivoting movement about a transverse axis of the mirror insert when removing it from the housing. Such a pivoting movement is still possible even with a very large height of the mirror insert and a narrow width of the light exit opening if the otherwise customary mounting of the mirror insert along a longitudinal edge of the housing can no longer be carried out.

Die Träger 4 dienen zugleich zur Halterung des Dachspiegels 3 und weisen hierzu Stege 43, 44 sowie Stützflächen 42 auf. Stützflächen 42 und Stege 43, 44 sind der schwingenförmigen Kontur des Dachspiegels 3 so angepasst, dass dieser nach dem Einstecken unter Vorspannung an diesen Stegen einerseits und mit jeweils einem Randstreifen 311 an den Stützflächen 42 andererseits anliegt. Die Stützflächen 42 für die Randstreifen 311 des Dachspiegels 3 sind gegenüber den Anschlagflächen 41 für die Randstreifen 211 der Seitenspiegel 21 so angeordnet, dass zwischen den Seitenspiegeln 21 und dem Dachspiegel 3 ein Spalt 5 freibleibt; dieser ermöglicht es, die Leuchte in Verbindung zu einem Gehäuse mit mindestens einer entsprechenden Öffnung zur Abluftabführung, auch als Abluftleuchte einzusetzen.The carriers 4 also serve to hold the roof mirror 3 and for this purpose have webs 43, 44 and support surfaces 42. Support surfaces 42 and webs 43, 44 are adapted to the rocker-shaped contour of the roof mirror 3 such that, after being inserted under prestress, it rests on these webs on the one hand and with an edge strip 311 on the support surfaces 42 on the other. The support surfaces 42 for the edge strips 311 of the roof mirror 3 are arranged opposite the stop surfaces 41 for the edge strips 211 of the side mirrors 21 such that a gap 5 remains free between the side mirrors 21 and the roof mirror 3; this makes it possible to use the luminaire in connection with a housing with at least one corresponding opening for exhaust air discharge, also as an exhaust air luminaire.

Die Seitenspiegel und der Dachspiegel können abweichend von dem dargestellten Beispiel auch asymmetrisch ausgebildet sein.The side mirrors and the roof mirror can also be designed asymmetrically, in deviation from the example shown.
