Abstract

Es wird eine Rundreflektorleuchte in Form einer Pendel- oder Einbauleuchte beschrieben, bei der der vom Leuchtmittel (3) ausgehende Lichtstrom durch ein Reflektororgan (4), das einen vorgebbaren Bereich des freien Endes des langgestreckten Leuchtmittels (3) umschließt, in einen gebündelt nach unten gerichteten Zentrallichtstrom und in einen gegen den Rundreflektor (1) gerichteten Radiallichtstrom aufgeteilt wird.

Figure 00000001
A circular reflector luminaire in the form of a pendant or recessed luminaire is described, in which the luminous flux emanating from the illuminant (3) is bundled downwards into one by a reflector element (4) which encloses a predeterminable region of the free end of the elongated illuminant (3) directed central luminous flux and is divided into a radial luminous flux directed against the round reflector (1).
