Problems solved by technology

[0003] The use of bolted connections requires undesirably cumbersome handling when changing illuminants or other maintenance work, whereas conventional releasable locking is used, especially in connection with heavier constructions (eg in the case of safety glass sheets) When connecting, difficulties may arise if complex special structures are not used due to the continuous and safe holding of the frame
[0004] Furthermore, it is disadvantageous, in particular in the case of swivel planar lighting devices, that due to the resulting instabilities caused by the illuminants and the open frame, two persons are often required for maintenance work and replacement of the illuminants to be carried out smoothly.

Embodiment Construction

[0021] figure 1 An exemplary embodiment of a lighting device according to the invention designed as a built-in lighting device is shown with a box-shaped housing 1 in which a plurality of illuminants 2 arranged in a row are accommodated. Frame 3 corresponds to housing 1 , which surrounds and supports a light exit surface 4 in the form of one or more layers of glass or plastic, preferably designed as light scattering. In the exemplary embodiment shown, a plurality of partial reflectors 5 corresponding to the respective light 2 are arranged on the light exit surface 4 .

[0022] The frame 3 is connected to the housing 1 via pairs of support arms 6 and control arms 7 which are arranged in the gap between the housing 1 and the frame 3 in the region of the end faces. All jibs 6, 7 are designed as flat jibs and require a small amount of space, that is to say they can be installed without problems in the narrow gap between the housing 1 and the frame 3, because they are also in the ...

Abstract

The invention relates to a lamp, especially a flat illumination device, an embedded-mounted light source and an analogue. The lamp has a housing for accommodating a light-emitting body and an attached electronic component as well as a frame corresponding to the casing, and for fixing a sheet-shaped light-outgoing surface. The lamp is characterized in that: the frame is connected with the housing on the end side through flat arm support; one side of the flat arm support is articulated on the inner wall of the housing, the other side is articulated on the outer side of end wall of the fame and is arranged in the gap zone between the casing and the frame; and the frame is pivotable between an opening position and a closing position, where free accessibility to an illuminant is ensured in theopening position and the closing position is in flush with an opening plane of the housing.

Description

technical field [0001] The present invention relates to a lighting device, especially a light source, a planar lighting device and the like, which has a housing for accommodating a luminous body and associated electronic components and a frame corresponding to the housing for fixing a sheet-like, In particular, the light exit surface is designed as light scattering. Background technique [0002] In this type of lighting device, the frame supporting the light exit surface is detachably connected to the housing in order to ensure the necessary accessibility to the illuminants. For this purpose, in known lighting devices, the frame is designed to be bolted to the housing, or a releasable locking connection is provided between the frame and the housing by applying pressure or tension, wherein, for safety reasons There is also often a safety cord installed between the housing and the frame. [0003] The use of bolted connections requires undesirably cumbersome handling when cha...
