§ Derartige Leuchten sind als sogen. Wandfluter bekannt. Sie "j haben eine extrem asymmetrische Lichtverteilung zur gleichmäßigen Ausleuchtung senkrechter Flächen wie beispielsweise Wänden, Regalen, Verkaufstresen. Die Leuchten müssen dabei '·. in einem bestimmten Abstand von der senkrechten Fläche P- montiert sein, um eine gleichmäßige Ausleuchtung zu erhalten. Dieser optimale Montageabstand ist etwa im Verhältnis 1 : 3 zur Aufhängehöhe bzw. Wandhöhe festgelegt. Auf- ;, grund baulicher Gegebenheiten oder nachträglicher Änderungen läßt sich diese Forderung praktisch oft nicht verwirklichen und somit werden auch keine idealen Beleuchtungsverhältnisse erreicht.§ Such lights are as so-called. Wallwashers known. "Y have an extremely asymmetrical light distribution for uniform illumination of vertical surfaces such as walls, shelves, sales counter. The lights having to '·. Be mounted at a certain distance from the vertical plane P, to obtain a uniform illumination. This optimum The mounting distance is set at a ratio of 1: 3 to the suspension height or wall height. Due to structural conditions or subsequent changes, this requirement can often not be achieved in practice and therefore ideal lighting conditions are not achieved.
( Der Neuerung liegt die Aufgabe zugrunde, eine Leuchte der vorbeschriebenen Art so zu verbessern, daß die LichtstSrkeindikatrix jeder einzelnen Leuchte an unterschiedliche Aufhängehöhen und Montageabstände optimal angepaßt werden kann.(The innovation is based on the task of creating a lamp of the the type described above so that the LichtstSrkeindikatrix Each individual lamp can be optimally adapted to different suspension heights and mounting distances.
Die Lösunc dieser Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Anspruchs 1. So lassen sich in vorteilhafter Weise unterschiedliche Bels'uchtungsaufgaben und Montagearten mit nur einem Leuchtentyp verwirklichen. Weiterbildungen und Ausgestaltungen der Neuerung sind in den Unteransprüchen angegeben.The solution to this problem results from the characteristic Features of claim 1. In this way, different lighting tasks and types of assembly can advantageously be carried out Realize with just one type of luminaire. Advanced training and refinements of the innovation are specified in the subclaims.
ι Anhand der Zeichnung sei die Neuerung nachstehend näher erläutert. The innovation is explained in more detail below with the aid of the drawing.
FH 84/13FH 84/13
Die in der einzigen Figur schematisch im Querschnitt gezeigte Leuchte hat ein langgestrecktes kastenförmiges Gehäuse 1, an dessen einer Längsseite la vorzugsweise eine Leuchtstofflampe 2 angeordnet ist. Diese ist von einem halbkreisförmigen Fangspiegel 3 umgeben, an dem sich ein annähernd parabolisch gekrümmter Umlenkspiegel 4 oberhalb einer Lichtaustrittsöffnung 5 der Leuchte anschließt. Der Umlenkspiegel 4 ist an der der Lampe abgekehrten Längsseite 1b des Gehäuses schwenkbar gelagert und bildet mit seiner Schwenkachse 4a zugleich die Begrenzung der Lichtaustrittsöffnung auf dieser Seite. An der gegenüberliegenden Seite wird die Lichtaustrittsöffnung durch eine Abwinklung 3a des Fangspiegels begrenzt. Damit ist auch der direkte Blick auf die Leuchtstofflampe von unten bis zu der durch einen Pfeil 6 angezeigten Ebene verwehrt.The lamp shown schematically in cross section in the single figure has an elongated box-shaped housing 1, a fluorescent lamp 2 is preferably arranged on one longitudinal side la. This is of a semicircular shape Surrounding secondary mirror 3, on which an approximately parabolically curved deflecting mirror 4 is located above a light exit opening 5 of the lamp connects. The deflection mirror 4 is on the longitudinal side 1b of the housing facing away from the lamp pivotally mounted and forms with its pivot axis 4a at the same time the delimitation of the light exit opening on this Page. The light exit opening is on the opposite side limited by a bend 3a of the secondary mirror. This also gives you a direct view of the fluorescent lamp from the bottom to that indicated by an arrow 6 Level denied.
Der Umlenkspiegel 4 greift mit seiner freien Kante 4b oberhalb der Leuchtstofflampe 2 unter den Fangspiegel 3. Dadurch ist sichergestellt, daß beim Verschwenken des Umlenkspiegels bis in die in Strichlinien angedeutete Stellung 41 keine größeren Lichtstromverluste auftreten. Der Schwenkbereich des Umlenkspiegels, der durch nicht dargestellte Mittel innerhalb dieses Bereiches jeweils feststellbar ist, umfaßt einen Winkel cC von etwa 15°. Damit läßt sich der Lichtstärkeverteilungskörper der Leuchte so verändern, daß das aus der Lichtaustrittsöffnung etwa in Richtung des Pfeiles 5a austretende Licht optimal die jeweilige Beleuchtungsaufgabe erfüllt.The deflecting mirror 4 engages with its free edge 4b above the fluorescent lamp 2 under the secondary mirror 3. This ensures that no major losses of luminous flux occur when the deflecting mirror is pivoted into the position 4 1 indicated in broken lines. The pivoting range of the deflection mirror, which can be determined by means not shown within this range, comprises an angle cC of approximately 15 °. The light intensity distribution body of the lamp can thus be changed in such a way that the light emerging from the light exit opening approximately in the direction of arrow 5a optimally fulfills the respective lighting task.
