Abstract

Das Leuchtengehäuse besteht aus einem Leuchtenoberteil (10) und einer das Oberteil (10) nach unten abschließenden Leuchtenwanne (11). Sowohl das Leuchten­ oberteil (10) als auch die Leuchtenwanne (11) sind an ihren Außenflächen mit einer feinkörnigen Struktur ver­ sehen. Dadurch erhält das gesamte Leuchtengehäuse eine einheitliche matte Außenfläche. Durch die licht­ streuende Wirkung der körnigen Struktur der Leuchten­ wanne werden Fremdlichtreflektionen vermieden, so daß Unebenheiten der Leuchtenwanne nicht durch Spiegelung sichtbar werden. Die lichtstreuenden Eigenschaften der Leuchtenwanne (11) werden verbessert. The luminaire housing consists of an upper part of the luminaire (10) and one the top (10) down final lamp tray (11). Both the glow Upper part (10) and the lamp tray (11) are on their outer surfaces with a fine-grained structure see. This gives the entire luminaire housing one uniform matt outer surface. By the light scattering effect of the granular structure of the lights tub are stray light reflections avoided, so that No unevenness in the luminaire tray due to reflection become visible. The light scattering properties of the Luminaire tray (11) are improved.
