Description
Leuchte zur Aufnahme eiiiiY'c@' enförmigen Lichtquelle Bekannte Glühlampenleuchten sind so ausgebildet, daß einerseits eine Lichtstrahltulg nach bevorzugten Richtungen, beispielsweise als Breitstrahlung, durch den Reflektor gelenkt wird, während` fein Teil des Lichtes durch den lichtdurchlässigen oberen Leuch= tenkörper nach oben gestrahlt wird.Luminaire to accommodate eiiiiY'c @ 'en-shaped light source Well-known incandescent lamps are designed so that, on the one hand, a light beam tulg in preferred directions, for example, as broad radiation, is directed through the reflector, while `fine Part of the light through the translucent upper luminaire body upwards is blasted.
Durch die Erfindung soll die Lichtverteilung einer derartigen Leuchte den Erfordernissen einer blendungsfreien Innen- oder Außenbeleuchtung angepaßt und durch die besondere Ausbildung ihres Reflektors eine gleichmäßige und wirtschaftliche Ausnutzung des von einer röhrenförmigen Lichtquelle, insbesondere einer Gasentladungsröhre, @ aus-; gestrahlten Lichtes gewährleistet werden.The light distribution of such a lamp is intended by the invention adapted to the requirements of glare-free indoor or outdoor lighting and due to the special design of its reflector, it is uniform and economical Utilization of the from a tubular light source, in particular a gas discharge tube, @ the end-; radiated light can be guaranteed.
Erfindungsgemäß wird der obere Rand der reflektierenden Zone des Schirmes, an den die lichtdurchlässige Zone .anschließt, mit der Achse der Leuchtröhre und dem unteren Rand der gegenüberliegenden Reflektorseite in eine Ebene gebracht und die Schirm-$äche so ausgebildet, daß sie an jener Begrenzungslinie annähernd senkrecht auf dieser Ebene steht. Auf diese Weise wird die bestmögliche Füllung des Reflektors mit dem Licht der Leuchtröhre und infolgedessen die beste Ausnutzung der Lichtquelle für die vom Reflektor zu beleuchtende Fläche erzielt. Andererseits wird so alles Licht, das nicht mit einer einmaligen Reflexion am Reflektor nutzbar gemacht werden kann, durch den lichtdurchlässigen Teil der Leuchtenglocke oder -mulde erfaßt und zur Aufhellung von über der Leuchte befindlichen Gebäudeteilen, wie Häuserfassaden o. dgl., .ausgenutzt. J In der Zeichnung ist ein Reflektor als Ausführungsbeispiel dargestellt,' und zwar in Abb. i in perspektivischer Ansicht, in Abb. 2 im Schnitt.According to the invention, the upper edge of the reflective zone of the screen, to which the translucent zone .anschlt, with the axis of the fluorescent tube and the lower edge of the opposite reflector side brought into a plane and the screen surface is designed in such a way that it is approximately perpendicular to that boundary line stands at this level. This way the best possible filling of the reflector will be achieved with the light of the fluorescent tube and consequently the best use of the light source for the area to be illuminated by the reflector. On the other hand, that's how everything turns out Light that cannot be made usable with a single reflection on the reflector can be detected through the translucent part of the lamp bell or trough and to brighten up parts of the building located above the luminaire, such as house facades or the like, .used. J The drawing shows a reflector as an exemplary embodiment shown, 'in Fig. i in perspective view, in Fig. 2 in section.
Die untere, verspiegelte Zone ist mit i, die obere, lichtdurchlässige, zweckmäßig innenmattierte Zone mit 2 bezeichnet. Beide Zonen i und 2 treffen dort zusammen, wo die punktiert eingezeichnete Verbindungslinie zwischen der Lichtquelle 3 und dem unteren Re$ektorrand q die Reflektorwarid schneidet, die mit dieser Verbindungslinie.etwa einen rechten Winkel bildet.The lower, mirrored zone is marked with i, the upper, translucent, appropriately internally frosted zone designated with 2. Both zones i and 2 meet there together where the dotted line connecting the light source 3 and the lower edge of the reflector q the reflector warid intersects with this connecting line forms a right angle.
