Der Gesamtaufbau der erfindungsgemäßen Leuchte 1 ist aus der perspektivischen Darstellung gemäß Fig. 1 zu erkennen.The overall structure of the luminaire 1 according to the invention is shown in perspective view Fig. 1 to recognize.

Das Leuchtengehäuse besteht im Wesentlichen aus eine Rückwand 30, an welcher senkrecht zu dieser stehend mit Hilfe von Senkkopfschrauben 16 Seitenteile 10 und 20 angeschraubt sind, welche an der Vorderseite über eine profilierte Schiene 40 miteinander verbunden sind. Auch diese ist mit Senkkopfschrauben 16 mit den Seitenteilen 10 und 20 verbunden.The luminaire housing consists essentially of a rear wall 30, to which perpendicular to this standing with the aid of countersunk screws 16 side parts 10 and 20 are screwed, which at the front over a profiled rail 40 with each other are connected. This is also connected with countersunk screws 16 with the side parts 10 and 20.

Die der Aufnahme der Senkkopfschrauben 16 dienenden Senklöcher 11 sind, wie vor allem Fig. 3a erkennen lässt, mit so genannten Kratznocken 12 versehen, welche beim Eindrehen der Senkkopfschraube den an dieser anhaftenden Lack abtragen und damit eine gute elektrische Verbindung zwischen den Seitenteilen 10, den Senkkopfschrauben 16 sowie der mit diesen verbundenen Rückwand 30 bzw. der vorderen Profilschiene 40 gewährleisten.The recording of the countersunk screws 16 serving sink holes 11 are, as above all Fig. 3a can recognize, provided with so-called Kratznocken 12, which ablate when adhering the countersunk screw adhering to this varnish and thus ensure a good electrical connection between the side members 10, the countersunk screws 16 and connected to these rear wall 30 and the front rail 40.

Innerhalb des Gehäuses befindet sich als Leuchtmittel eine Leuchtstofflampe 2, welche in an den Seitenteilen 10 und 20 angebrachten Lampensockeln 3 eingesetzt ist.Within the housing is located as a fluorescent lamp 2, which is inserted in mounted on the side parts 10 and 20 lamp sockets 3.

Zwischen Rückwand 30 und Leuchtstofflampe 2 sind Reflektoren angeordnet, von welchen die Reflektorflächen 61a und 62c in der Zeichnung erkennbar sind.Between the rear wall 30 and fluorescent lamp 2 reflectors are arranged, of which the reflector surfaces 61a and 62c can be seen in the drawing.

Nach oben und unten ist die Leuchte durch transparente Blenden abgedeckt, von welchen in Fig. 1 nur die nach oben aufgeklappte Blende 50 gezeigt ist.Up and down, the lamp is covered by transparent panels, of which in Fig. 1 only the upwardly opened aperture 50 is shown.

Zur elektrischen Verbindung der Leuchte sind innerhalb des Leuchtengehäuses zwischen Rückwand 30 und Reflektor 61a Verbindungskabel 91 vorgesehen, deren an den Enden befindliche Stecker 92 und Steckbuchsen 93 zu sehen sind, welche durch in den Seitenwänden 10 bzw. 20 vorgesehene Durchführungsöffnungen 18 bzw. 18' hindurchgeführt werden können. Ferner sind in den Seitenteilen 10 und 20 einander zugeordnete Arretierbolzen 15 und Rastöffnungen 17 vorgesehen, welche, wie weiter unten erläutert ist, der Ausrichtung und Arretierung der in einer Reihe angeordneten Leuchtenelemente dienen.For electrical connection of the lamp connecting cable 91 are provided within the lamp housing between the rear wall 30 and reflector 61a, which are located at the ends plug 92 and sockets 93 can be seen, which passed through provided in the side walls 10 and 20 through openings 18 and 18 ' can be. Furthermore, 10 and 20 associated locking pins 15 and latching openings 17 are provided in the side parts, which, as explained below, serve the alignment and locking of the arranged in a row lamp elements.

Zur Befestigung der Leuchte 1 an einer in Fig. 1 nicht dargestellten Rückwand sind schlüssellochförmige Durchbrüche 31 in Reihe nebeneinander vorgesehen.To attach the light 1 to an in Fig. 1 not shown back wall keyhole-shaped apertures 31 are provided in series next to each other.

Die für die Gestaltung der erfindungsgemäßen Leuchte wichtigsten Maßnahmen beziehen sich auf die Lichtverteilung und Lichtführung, wie letztere mit dem Querschnitt gemäß Fig. 2 veranschaulicht sind, in welchem die von der Lampe 2 erzeugten Lichtstrahlen zur Erzeugung des Indirektlichtes A, zur Erzeugung des Direktlichtes B sowie des Seitenlichtes C schematisch angedeutet sind.The most important measures for the design of the lamp according to the invention relate to the light distribution and light guidance, as the latter with the cross section according to Fig. 2 are illustrated, in which the light beams generated by the lamp 2 for generating the indirect light A, for generating the direct light B and the side light C are indicated schematically.

Die hier symbolisierte Lichtführung wird ermöglicht durch die besondere Gestaltung des hinteren Reflektors mit den Reflektorflächen 61a und 61b sowie des vorderen Reflektors mit den Reflektorflächen 62a, 62b und 62c und den Blenden 50 und 70.The symbolized here light guide is made possible by the special design of the rear reflector with the reflector surfaces 61a and 61b and the front reflector with the reflector surfaces 62a, 62b and 62c and the aperture 50 and 70th

Die Reflektorflächen 61a und 62a begrenzen eine sich nach unten trichterförmig öffnende untere Kammer 63, die Reflektorflächen 61b, 62b und 62c eine sich nach oben trichterförmig öffnende obere Kammer 64.The reflector surfaces 61a and 62a delimit a lower chamber 63 opening downwards in a funnel shape, the reflector surfaces 61b, 62b and 62c delimiting an upper chamber 64 which opens upwards in a funnel-shaped manner.

Die untere Kammer 63 ist durch eine untere Blende 70 mit rillenförmiger Struktur abgedeckt. Die Reflektorflächen 61a und 62a bewirken zusammen mit der gerillten unteren Blende 70, dass das von der Lampe 2 erzeugte Licht zur Beleuchtung des Arbeitsplatzes vor allem senkrecht nach unten in Richtung B abgelenkt wird, während seitlich austretendes Licht in Richtung C weitgehend unterdrückt wird, was zu einer außerordentlich guten Blendfreiheit führt.The lower chamber 63 is covered by a lower aperture 70 with a groove-like structure. The reflector surfaces 61a and 62a, together with the grooved lower panel 70, cause the light generated by the lamp 2 to illuminate the workstation to be deflected mainly vertically downwards in the direction B, while laterally exiting light in the direction C is largely suppressed, resulting in an extremely good glare-free leads.

Die obere Kammer 64 ist durch eine mattierte Blende 50 abgedeckt. Das von der Lampe 20 nach oben abgegebene Licht wird mittels der Reflektorflächen 61b, 62b und 62c reflektiert und mittels der mattierten Blende 50 in stärkerem Maße als mit der unteren Blende 70 diffus gestreut, wodurch ein in Richtung A austretendes, von der Raumdecke reflektiertes Indirektlicht erzeugt wird.The upper chamber 64 is covered by a frosted aperture 50. The light emitted upward from the lamp 20 becomes reflected by the reflector surfaces 61b, 62b and 62c and diffused by means of the matted aperture 50 to a greater extent than with the lower aperture 70, whereby an emerging in the direction A, reflected from the ceiling indirect light is generated.

Aus konstruktiven Gründen sind die Reflektorflächen 61a und 61b bzw. die Reflektorflächen 62a, 62b und 62c einstückig hergestellt.For structural reasons, the reflector surfaces 61a and 61b and the reflector surfaces 62a, 62b and 62c are made in one piece.

Für Herstellung, Montage und Wartung nicht weniger wichtig sind die mit der Erfindung ferner vorgeschlagenen konstruktiven Maßnahmen, welche anhand der weiteren Figuren genauer erläutert sind.No less important for manufacture, assembly and maintenance are the structural measures proposed with the invention, which are explained in more detail with reference to the further figures.

Für Montage und Wartung wichtig ist die Gestaltung und Anordnung der oberen Blende 50 und der unteren Blende 70, welche zwischen der Rückwand 30 und der vorn gelegenen Schiene 40, die zweckmäßigerweise als Strangpressprofil hergestellt sind, angeordnet sind.Important for assembly and maintenance is the design and arrangement of the upper panel 50 and the lower panel 70, which are arranged between the rear wall 30 and the front rail 40, which are suitably made as an extruded profile.

Die obere Blende 50 ist mit einer am hinteren Rand 51 befindlichen, nach unten abgekröpften Lippe 51a in eine am oberen Rand der Rückwand vorgesehenen Rille 35 verschwenkbar eingehängt. Damit kann die obere Blende 50, wie mit Fig. 4a gezeigt ist, nach oben weggeschwenkt werden. Eine gleichfalls am hinteren Rand der oberen Blende 50 parallel zur Lippe 51a verlaufende vordere Lippe 51b, welche an dem die Rille 35 begrenzenden vorderen Wandteil 35a der Rückwand 30 anliegt, verhindert, dass die obere Blende 50 beim Hochklappen gelöst wird. Auch lässt sich die obere Blende 50 aufgrund dieser speziellen Formgebung ohne Werkzeug einfach montieren bzw. demontieren. Zweckmäßigerweise läuft die Rückwand 30 nach oben in eine einen Anschlag für die Blende 50 bildende Verlängerung 35c aus, deren Funktionsweise vor allem aus Fig. 7 ersichtlich ist.The upper panel 50 is pivotally mounted with a located at the rear edge 51, bent down lip 51a in a provided on the upper edge of the rear wall groove 35. Thus, the upper panel 50, as with Fig. 4a is shown, are swung upwards. A likewise at the rear edge of the upper panel 50 parallel to the lip 51 a extending front lip 51 b, which abuts the groove 35 delimiting the front wall portion 35 a of the rear wall 30, prevents the upper panel 50 is released during folding. Also allows the upper panel 50 due to this special shape without tools easy to assemble or disassemble. Expediently, the rear wall 30 runs upwards into an extension 35c which forms a stop for the panel 50, the function of which mainly consists of Fig. 7 is apparent.

Diese Gestaltung ermöglicht, dass die Blende 50 im hochgeklappten Zustand arretiert ist, sodass der Servicetechniker beim Lampenwechsel, der Reparatur oder der Reinigung beide Hände frei hat.This design allows the bezel 50 to be locked in the folded up position so that the service technician has both hands free for lamp replacement, repair or cleaning.

An ihrem vorderen Ende greift die geschlossene obere Blende 50 mit einer nach unten gerichteten elastisch federnden Lippe 52 zur Arretierung in eine Nut 42 der Profilschiene 40 ein. Die obere Blende 50 sowie die Profilschiene 40 sind so dimensioniert, dass bei geschlossener Blende 50 deren Oberfläche mit der Oberfläche der Schiene 40 bündig ist, sodass sich zwischen den einander benachbarten Kanten von Blende 50 und Schiene 40 nur ein schmaler Spalt ergibt. Damit ist ein versehentliches Öffnen der Blende weitgehend verhindert, da zum Öffnen ein Werkzeug, z. B. ein in den Spalt einzuführender Schraubendreher, erforderlich ist.At its front end, the closed upper panel 50 engages with a downwardly directed elastically resilient lip 52 for locking in a groove 42 of the rail 40 a. The upper panel 50 and the rail 40 are dimensioned so that when the shutter 50 is closed, its surface is flush with the surface of the rail 40, so that there is only a narrow gap between the adjacent edges of the panel 50 and rail 40. This accidental opening of the aperture is largely prevented, as to open a tool, for. As an inserted into the gap screwdriver is required.

Während zu Servicezwecken, z. B. zum Austausch einer Lampe 2, es genügt, die obere Blende 50 zu öffnen, kann die untere Blende 70 fest montiert bleiben. Jedoch sind zur Ermöglichung einer wirtschaftlichen Fertigung Rückwand 30, Schiene 40 und die Seitenteile 10 und 20 so gestaltet, dass eine einfache Montage und Demontage möglich ist.While for service purposes, eg. B. to replace a lamp 2, it is sufficient to open the upper panel 50, the lower panel 70 remain firmly mounted. However, to enable economical manufacturing, rear wall 30, rail 40 and side members 10 and 20 are designed to allow easy assembly and disassembly.

So weist die Blende 70 beidseitig gegenüber der Blendenstärke verjüngte Ränder 71 auf, welche einerends in eine Nut 32 der profilierten Rückwand 30 und anderenends in eine Nut 41 der profilierten Schiene 40 lösbar eingesetzt ist. Der Abstand zwischen den einander zugewandten Rändern 32a der Rückwand 30 und 41a der Schiene 40 ist geringer als die Breite der eingesetzten Blende 70, der Abstand der Böden 41b der Nut 41 und 32b der Nut 32 dagegen größer als die Breite der unteren Blende 70, wodurch zum einen ein leichtes Einsetzen und Halten der Blende 70 gesichert ist. Um die Blende 70 in ihrer Position zu fixieren, greift in den Zwischenraum zwischen Nutenboden 32b und dem Rand 71 der Blende 70 ein Fixierstift 13 ein, welcher, wie vor allem Fig. 3 zeigt, am Seitenteil 10 vorgesehen ist. Die Ränder 71 und 72 der unteren Blende 70 sowie die Blende sind so bemessen, dass sich bei eingesetzter Blende 70 ein stufenloser Übergang ergibt.Thus, the diaphragm 70 on both sides against the diaphragm thickness tapered edges 71, which is at one end in a groove 32 of the profiled rear wall 30 and the other end in a groove 41 of the profiled rail 40 releasably inserted. The distance between the mutually facing edges 32 a of the rear wall 30 and 41a of the rail 40 is less than the width of the inserted aperture 70, the distance of the bottoms 41b of the groove 41 and 32b of the groove 32, however, greater than the width of the lower aperture 70, whereby on the one hand a slight insertion and holding the aperture 70 secured is. In order to fix the diaphragm 70 in its position, engages in the space between groove bottom 32b and the edge 71 of the diaphragm 70, a fixing pin 13, which, as above all Fig. 3 shows, is provided on the side part 10. The edges 71 and 72 of the lower panel 70 and the aperture are sized so that when inserted aperture 70 results in a smooth transition.

Insbesondere bei Verwendung der Leuchte als Leuchtenelement in einem Lichtband ist deren einfache und fluchtende Montage notwendig. Zu diesem Zweck sind in der Rückwand 30 der Leuchte 1 eine Reihe von schlüssellochförmigen Durchbrüchen 31 vorgesehen, die bereits im Zusammenhang mit Fig. 1 erwähnt sind. Deren besondere Ausbildung zeigt die perspektivische Darstellung gemäß Fig. 5a. Die Leuchte 1 wird bei der Montage auf am Versorgungskanal 80 befindliche Gewindestifte 81 aufgesetzt, welche die schlüssellochförmigen Durchbrüche 31 durchsetzen. Zur Festlegung der Leuchte 1 sind die auf den Gewindestiften 81 aufgeschraubten Muttern, vorzugsweise Sperrzahnmuttern 33, anzuziehen. Das am Durchbruch 31 vorgesehene Langloch 31a ermöglicht ein Ausrichten der Leuchte 1 in vertikaler Richtung.In particular, when using the lamp as a lighting element in a light strip whose simple and flush mounting is necessary. For this purpose, a number of keyhole-shaped openings 31 are provided in the rear wall 30 of the lamp 1, which already in connection with Fig. 1 are mentioned. Their special training shows the perspective view according to Fig. 5a , The lamp 1 is placed during assembly on the supply channel 80 located threaded pins 81 which pass through the keyhole-shaped openings 31. To fix the lamp 1, the screwed onto the grub screws 81 nuts, preferably locking nuts 33, are attracted. The opening 31 provided on the slot 31a allows alignment of the lamp 1 in the vertical direction.

Zur weiteren Lagefixierung und Halterung der Leuchte ist am unteren Ende des Versorgungskanals 80 eine nach oben abgekröpfte Lasche 82 vorgesehen, welche in eine Aufnahmerille 36 der Rückwand 30 eingreift. Damit ist eine sichere Befestigung der Leuchte gewährleistet. Sobald die Leuchte 1 an den Gewindestiften 81 aufgehängt und die Sperrzahnmuttern 33 aufgeschraubt sind, ist die Leuchte fixiert. Die Lasche 82 verhindert, dass die Leuchte nach oben geschoben werden kann. Selbst wenn das Anziehen der Sperrzahnmutter 33 unterbleibt, ist eine sichere Befestigung gewährleistet.For further fixation of the position and mounting of the lamp, an upwardly cranked tab 82 is provided at the lower end of the supply channel 80, which engages in a receiving groove 36 of the rear wall 30. For a secure attachment of the lamp is guaranteed. Once the lamp 1 is suspended from the grub screws 81 and the locking teeth nuts 33 are screwed, the lamp is fixed. The tab 82 prevents that the light can be pushed upwards. Even if the tightening of the ratchet nut 33 is omitted, a secure attachment is ensured.

Bei Verwendung der Leuchtenelemente 1, 1' in einem Leuchtenband, wie dies mit Fig. 6 veranschaulicht ist, ist es wichtig, dass diese so ausgerichtet sind, dass sie miteinander fluchten.When using the lamp elements 1, 1 'in a light strip, as with Fig. 6 illustrated, it is important that they are aligned so that they are aligned.

Um dies zu gewährleisten bzw. zu erleichtern, ist jeweils in einer Seitenwand 10' ein federbelasteter Arretierbolzen 15' vorgesehen, welcher in eine diesem zugeordnete, z. B. in den Figuren 1 und 3 erkennbare, Rastöffnung 17 eingreift. Bei der Demontage ist dieser Arretierbolzen 15' zu lösen.To ensure or facilitate this, in each case in a side wall 10 ', a spring-loaded locking pin 15' is provided, which in an associated with this, z. Tie FIGS. 1 and 3 recognizable, latching opening 17 engages. When disassembling this locking pin 15 'is to be solved.

Um ein Leuchtenelement 1 oder 1' aus dem Lichtband herauszunehmen, müssen nicht nur die Befestigungs- und Verriegelungselemente 81 und 15 gelöst, sondern auch die elektrischen Verbindungen der Kabel 91, 91' voneinander getrennt werden. Aus diesem Grunde sind die Kabel 91, 91' an ihren einander zugeordneten Enden mit Steckern 92' bzw. Steckbuchsen 93 ausgerüstet, die leicht miteinander verbunden bzw. voneinander getrennt werden können.To remove a lighting element 1 or 1 'from the light band, not only the fastening and locking elements 81 and 15 must be solved, but also the electrical connections of the cables 91, 91' are separated from each other. For this reason, the cables 91, 91 'at their mutually associated ends with plugs 92' and sockets 93 equipped, which can be easily connected to each other or separated from each other.

Die Räume zwischen den Rückwänden 30, 30' und den Reflektorflächen 61a und 61a' sind so bemessen, dass nach Trennen der Anschlusskabel 91 und 91' diese zusammen mit ihren Steckbuchsen 93 und den Steckern 91' hinter den Reflektoren 61a und 61a' problemlos verstaut werden können.The spaces between the rear walls 30, 30 'and the reflector surfaces 61a and 61a' are dimensioned such that, after disconnecting the connection cables 91 and 91 ', these together with their sockets 93 and the plugs 91' are easily stowed behind the reflectors 61a and 61a ' can.
