Embodiment Construction

[0025] The recessed floor lighting, all designated with "1", has a mounting frame which is placed from above and is inserted, for example, into a mounting hole 3 which has a hole opening 3 a in a floor 2 with a surface 2 a. According to attached figure 2 and 3 , the mounting hole 3 and the horizontal section of the recessed floor lighting device 1 can be round, or according to the attached Figures 4 to 7 , which can be angular, such as rectangular or square.

[0026] The main part of the recessed floor lighting device 1 is an installation base frame, and the installation base frame can form one piece or two pieces with the lower installation base frame 4 and the upper receiving frame 11 . The mounting base frame 4 is fixed in the mounting hole 3 at a distance a from the surface 2a, and it may have means for anchoring in the floor 2 for this purpose. The mounting base frame 4 is preferably formed by the upper edge of a mounting shell 4a having a peripheral wall 4b and a bo...

Abstract

The invention relates to an in-ground light (1) which comprises a mounting frame (10), a lamp support (12) and a transparent cover (26) that is at least partially recessed into the mounting frame (10)and sealed off. The mounting frame (10) has an annular shoulder area at a downward distance from its upper edge, which supports the lamp support (12) with a flange (12a). The transparent cover (26) overlaps the flange (12a) and is supported thereon. An annular seal (28) is interposed between the flange (12a) and the transparent cover (26). The aim of the invention is to improve the seal's impermeability to surface water. For this purpose, a first sealing ring (13) is interposed between the inner peripheral surface of the mounting frame (10) and the outer peripheral surface of the flange (12a)and / or between the shoulder area and the flange (12a).

Description

technical field [0001] The invention relates to a recessed floor lighting device, ie a lighting device that can be installed in an installation opening in a floor. Background technique [0002] In contrast to recessed wall or ceiling lighting, recessed floor lighting must meet special requirements. The first requirement is a special strength, since the recessed floor lighting replaces the floor in the area of ​​the installation opening and must therefore have the required load-bearing capacity. Another requirement includes special sealing of the recessed floor lighting to prevent water from flowing into the recessed lighting fixture due to gravity. [0003] In DE 199 18 872 A1 the above-mentioned recessed floor lighting is described. This previously known recessed floor lighting device has a one-piece mounting frame with an inner flange on its inner side at a distance from its upper edge, on which the outer flange of the lamp carrier bears. The flat cover bears on this ou...
