Light fixture with a linear lighting field, suitable for forming lighting trunking

Abstract

In a long field lighting fixture or lighting fixture with a linear lighting field, which is capable of forming a light screen or row of light fixtures that is reduced to its functionally critical parts, the lamp housing is composed of a single-piece reflector arrangement that is fashioned mirror-symmetrically with reference to a vertical middle lamp plane. This is composed of a thin-walled material whose surface is finely structured in a stiffening fashion by surface shaping at least in sub-areas. Facing away from its light exit opening, the reflector arrangement also comprises a pair of outwardly salient, mutually spaced legs, which are spaced apart by a cover surface, for the acceptance of electrical and/or mechanical lighting fixture component parts. Connector elements for a screen arrangement are formed either by end face parts or plates of the lighting fixture itself or by individual elements. To that end, the end face parts comprise a plug channel on an inside surface facing toward the reflector arrangement which channel corresponds to the profile thereof. A tongue and groove profile is provided on the outside surface by which two end face parts can be joined in one another and align a pair of fixtures with identical contour. Further structural elements and components of the lighting technology supplement the lighting fixture structure to form a lighting fixture system.
