Abstract

In dem Leuchtengehäuse (10) befindet sich zwischen der Lampe (11) der unteren Lichtaustrittsöffnung (12) ein optischer Körper (20) mit lichtbrechenden Eigen­ schaften. Die Breite des optischen Körpers (20) ist so bemessen, daß der Abschirmwinkel des optischen Körpers - bezogen auf die Lampe (11) - im wesentlichen gleich der freien Lichtausstrahlung des Leuchtengehäuses ist. Der optische Körper (20) besteht aus einem kompakten Block, dessen Oberseite und Unterseite jeweils min­ destens maximal eine einzige konkave Knicklinie auf­ weisen. Die durch den optischen Körper (20) hindurch­ gehende direkte Strahlung wird durch Brechung ab­ gelenkt, um eine geeignete Lichtverteilung zu erhalten. Die Leuchte hat bei genauer Einhaltung der gewünschten Lichtlenkung einen hohen Wirkungsgrad, weil die für die Lichtlenkung erforderlichen Reflexionen auf ein Minimum beschränkt sind. In the lamp housing (10) is between the Lamp (11) of the lower light outlet opening (12) optical body (20) with refractive properties create. The width of the optical body (20) is like this dimensioned that the shielding angle of the optical body - Based on the lamp (11) - substantially the same is the free light emission of the lamp housing. The optical body (20) consists of a compact Block, the top and bottom of each min a maximum of one concave crease line point. Through the optical body (20) outgoing direct radiation is refracted directed to obtain a suitable light distribution. The luminaire has the required if exactly adhered to Light control has a high degree of efficiency because of that for the Light control required reflections to a minimum are limited.
