Abstract

Der erfindungsgemässe Beleuchtungskörper (1) besteht aus einem U-förmigen Stangenprofil (16), das an der offenen Seite mit einer transparenten Abdeckung (20) versehen ist und in dem in dichter Packung hintereinander mehrere Module (3) eingeschoben sind. Die Module (3) bestehen aus einem Kunststoffgehäuse (4) mit einer Bodenplatte (5), auf der Trägerstege (6) angeformt sind. Die Trägerstege (6) definieren zueinander geneigte Auflageflächen, auf die Leiterplattenstreifen (7) aufliegen. Auf den Leiterplattenstreifen (7) sind eine Vielzahl von LED's in einer Reihe hintereinander angeordnet. Die LED's (2) haben einen Ausstrahlungswinkel (β). Bevorzugterweise entsprechen der Ausstrahlungswinkel (β) und die Neigung zweier benachbarter Leiterplattenstreifen (α) einander etwa. Mehrere Module (3) sind hintereinander auf einer gemeinsamen Schiene (8) mittels Schrauben (28) befestigt und lassen sich so vormontiert in das Stangenprofil (16) einschieben, welches entsprechende Längsstege (17) mit Längsführungsrillen (18) aufweist.

The lighting fixture (1) according to the invention consists of a U-shaped rod profile (16) which is provided on the open side with a transparent cover (20) and in which several modules (3) are inserted one behind the other in a tight packing. The modules (3) consist of a plastic housing (4) with a base plate (5) on which carrier webs (6) are molded. The carrier webs (6) define mutually inclined support surfaces on which printed circuit board strips (7) rest. A large number of LEDs are arranged in a row on the circuit board strip (7). The LEDs (2) have a beam angle (β). The radiation angle (β) and the inclination of two adjacent circuit board strips (α) preferably correspond approximately to one another. Several modules (3) are fastened one behind the other on a common rail (8) by means of screws (28) and can thus be preassembled into the rod profile (16), which has corresponding longitudinal webs (17) with longitudinal guide grooves (18).
