Embodiment Construction

[0023] figure 1 The main part of the illuminator represented by reference numeral 1 in the middle is a trough-shaped housing 2, a cover 4 detachably connected to the trough-shaped housing 2 through a plurality of locking devices 3 distributed around, and a cover 4 arranged in the trough A lamp 6 in the cavity 5 between the housing 2 and the cover 4 is connected and held on at least one not shown mechanical and electrical connecting element. The cover 4 is formed in a dome shape. Thus, the wall 4a of the enclosure extends in an arcuate or U-shaped section.

[0024] In the case of the present embodiment, a moisture-proof luminaire is included, which in this respect meets special protection requirements, such as protection against the intrusion of spray water, especially the demarcation connection 7 between the trough-shaped housing 2 and the cover 4 Protect the area from spray water. This protection can be provided in the area of ​​the demarcation connection 7, for example by...

Abstract

A luminaire (1), in particular damp-proof luminaire, having an elongate, trough-shaped housing (2), terminals arranged therein for at least one lamp (6), a transparent cover (4) covering the opening of the housing (2) and longitudinally extending fiberoptic ribs (23), which are preferably provided, in the cover (4). In order to broaden the possibilities in design terms of the cover (4), at least one cross-sectional dimension (B, T) of the cover (4) is reduced from its longitudinal center or a point in a longitudinal center region (L2) towards the respectively associated end region of the cover (4).

Description

technical field [0001] The invention relates to a luminaire according to the preamble of claim 1 . Background technique [0002] The luminaire is constructed with a housing in two parts, one part being a channel-shaped housing with fastening elements for fixing to a carrier such as a wall or ceiling; the other part being made of an at least partially transparent A cover is formed which is detachably connected to the channel housing via locking elements. In the luminaire housing formed by the trough-shaped housing and the cover, a lamp can be connected mechanically and electrically, the light emitted by the lamp in operation being emitted through the transparent cover for room lighting. In the case of this known luminaire, the side walls of the housing and / or the cover or the walls of the cover extend parallel to the longitudinal direction of the luminaire in the region of its top ridge contour or the like. [0003] Such a luminaire is described, for example, in EP 0 785 39...
