Abstract

Eine Reflektorleuchte mit einer Lampe (25) weist ein langgestrecktes Leuchtengehäuse (10) auf, in der ein Sekundärreflektor (12) gehalten ist. Mit einem an beiden Enden des Leuchtengehäuses (10) angeordneten Gehäusewand (15) ist über eine Aufhängung (20) ein Haltering (22) verbunden. In dem Haltering (22) ist ein als formstabiler Formkörper ausgebildeter Diffusor (23) angeordnet. In den Diffusor (23) ist ein mit Schlitzen (27) versehener Primärreflektor (24) eingeschoben. Von der Lampe (25) abgegebene Strahlen (30) treten somit entweder durch die Schlitze (27) des Primärreflektors aus und werden von dem Diffusor (23) gestreut oder werden als Strahlen (33) durch eine Reflexion an dem Primärreflektor (24) zu dem Sekundärreflektor (12) umgelenkt. Von der Oberfläche des Sekundärreflektors (12) werden die Strahlen (32,34) diffus reflektiert.

Figure 00000001
A reflector lamp with a lamp (25) has an elongated lamp housing (10) in which a secondary reflector (12) is held. A retaining ring (22) is connected to a housing wall (15) arranged on both ends of the lamp housing (10) via a suspension (20). A diffuser (23) designed as a dimensionally stable molded body is arranged in the retaining ring (22). A primary reflector (24) provided with slots (27) is inserted into the diffuser (23). Rays (30) emitted by the lamp (25) thus either exit through the slots (27) of the primary reflector and are scattered by the diffuser (23) or become rays (33) by reflection on the primary reflector (24) Secondary reflector (12) deflected. The rays (32, 34) are reflected diffusely from the surface of the secondary reflector (12).
