Description
Es sind bereits breitstrahlende Leuchten bekannt geworden, bei denen normale Leuchtstofflampen übereinander angeordnet sind und mit einem horizontalen, ebenen Spiegel zusammenwirken. Außerdem kann statt des ebenen Spiegels ein schwingenförinig gebogener Spiegel vorgesehen sein. Weiterhin sind Anordnungen bekannt, bei denen die Lampen parallel nebeneinander angeordnet sind und mit einem mehrfach gewölbten Spiegel zusammenwirken. Diese Leuchten haben zwar eine gute Breitstrahlung, jedoch läßt sich die Forderung nach Blendvngsfreiheit nicht verwirklichen, da sonst entweder die breitetrahlende Lichtverteilung verloren geht oder der Wirkungsgrad der Leuchte ungünstig wird.There are already wide beam luminaires known where normal fluorescent lamps are arranged one above the other and with a horizontal, work together flat mirror. In addition, a swing-shaped mirror can be used instead of the flat mirror curved mirror may be provided. Furthermore, arrangements are known in which the lamps are arranged parallel to each other and with a multi-arched one Mirrors work together. These lights have a good broad radiation, however the requirement for freedom from glare cannot be achieved, otherwise either the broad light distribution is lost or the efficiency of the luminaire becomes unfavorable.
Außerdem sind verschiedene leuchten bekannt geworden, die diese Forderungen
mehr oder weniger erfüllen. Bekannte Leuchten. mit breitetrahlender Lichtverteilungskurve
verwenden z. B. Reflex-
Die Neuerung betrifft eine breitstrahlende Leuchte mit zwei parallel nebeneinander angeordneten, langgestreckten, röhrenförmigen Lichtquellen, insbesondere leuchtstofflampen, bei der die oben beschriebenen Nachteile vermieden sind. Neuerungsgemäß wird dies dadurch erreicht, daß die Lampen mit einem Spiegel zusammenwirken, der im Querschnitt die Form eines nach unten offenen, gleichmäßigen Trapezes besitzt. Der Spiegel kann entlang seiner Mittellinie unterbrochen sein.The innovation concerns a wide beam luminaire with two parallel Elongated, tubular light sources arranged next to one another, in particular fluorescent lamps in which the disadvantages described above are avoided. According to the innovation this is achieved in that the lamps interact with a mirror that has the shape of a downwardly open, uniform trapezoid in cross section. The mirror can be interrupted along its center line.
Im folgenden ist auf die Zeichnung, die zwei Ausführungsbeispiele der Neuerung zeigt, Bezug genommen. Die Ausführungsbeispiele sind in den Fig. 1 und 2 im Querschnitt dargestellt. Fig. 3 zeigt eine Lichtverteilungskurve.The following is based on the drawing, the two exemplary embodiments the innovation shows, referred to. The exemplary embodiments are shown in FIG. 1 and 2 shown in cross section. Fig. 3 shows a light distribution curve.
Das aus dem Oberteil 1 und der lichtdurchlässigen Abdeckung 2 bestehende Leuchtengehäuse enthält, wie nicht besonders dargestellt, die Vorschaltgeräte, anschlußelemente, Fassungen u. dgl. für den Betrieb der Lampen. Als Lichtquellen sind zwei parallel nebeneinander angeordnete Leuchtstofflampen 3 vorgesehen, die mit einem Spiegel 4 zusammenwirken. Der Spiegel hat im Querschnitt die Form eines nach unten offenen, gleichmäßigen Trapezes. Die Längskanten 5 des Spiegels bilden mit dem waagerecht angeordneten Spiegelteil einen Winkel von etwa 100je Durch diese Anordnung erhält man eine Lichtverteilungskurve 6, wie Fig. 3 zeigte Das Maximum der Lichtausstrahlung liegt etwa bei einem Winkel von 50° zur Waagerechten.The one consisting of the upper part 1 and the transparent cover 2 The luminaire housing contains, as not specifically shown, the ballasts, connecting elements, Sockets and the like for operating the lamps. Two parallel light sources are used as light sources side by side fluorescent lamps 3 provided with a mirror 4 interact. The cross-section of the mirror has the shape of a downwardly open, uniform trapezoid. The longitudinal edges 5 of the mirror form horizontally with the arranged mirror part an angle of about 100 each is obtained by this arrangement one one Light distribution curve 6, as shown in Fig. 3, the maximum the light emission is approximately at an angle of 50 ° to the horizontal.
In einem Winkel kleiner als 15° zur Waagerechten ist die Lichtausstrahlung nahezu null, so daß die Leuchte blendungsfrei ist.The light emission is at an angle less than 15 ° to the horizontal almost zero, so that the lamp is glare-free.
Bei dieser Anordnung hat man den Vorteil, daß sich der Spiegel der
Leuchte in besonders einfacher Weise herstellen läßt, da keine für die Lichtausstrahlung
erforderliche Krümmung vorhanden ist.
Die neuerungsgemäße Leuchte besitzt eine breitstrahlende Lichtverteilung und ist außerdem blendungsfrei. Schließlich ist man nicht auf die Verwendung von Reflexschicht-Leuohtatofflampen angewiesen.The luminaire according to the innovation has a wide beam light distribution and is also glare-free. After all, one isn't on the use of Reflective layer Leuohtatofflampen instructed.
