Description

The invention relates to a lighting device with a supporting structure or supporting base, directly or indirectly on a ceiling or wall of a room is attachable.

One or more lights in a room not only serve the purpose of closing the room illuminate, but they are also a design element of the room, being both because of their arrangement and shape as well as because of the light that they emit, help shape the room and influence the Exercise well-being of the people in the room. An essential one The requirement for room lighting is that with sufficient lighting of the room the human eye is not blinded. In this regard, there are already one Numerous anti-glare devices have been developed, particularly when the Viewers looking up at a relatively flat angle are effective. The greater the light, the greater the light, the greater the risk of glare Lamp is emitted. To ensure that the room is sufficiently illuminated To keep the light intensity of a lamp as low as possible, several lamps arranged correspondingly lower light intensity, with the risk of glare is reduced due to the lower light intensity of the lights. In the presence However, if there are several lights, the spaces between the lights will be dated human eye as annoying dark spots. To solve this Problems have already been developed that directly and indirectly affect the space illuminate, however, such lights are relatively complex and expensive, whereby at the same time, special demands are placed on the ceiling or wall of the room are who carries the lights. In order to avoid dark spots between So-called luminous ceilings have already been proposed for several luminaires. Such a lighting device can e.g. from a plurality of individual lights the light bar be formed, on the emission side of which is continuous extending translucent cover member is arranged, e.g. a special one milky-white film is stretched out by the edge of the lighting device arranged connecting elements with the supporting structure of the Lighting device is connected. Such a lighting device can Area of the entire room boundary surface (ceiling, wall) or only in the area part of it may be arranged. If special lighting effects are desired, these can be achieved in that those located behind the cover element Lamps produce light of different colors. Such a lighting device is complex to manufacture and assemble, taking into account that considerable clamping forces are required to pull the cover element, e.g. a slide in an essentially straight extension on the radiation side of the Hold lighting device.

The invention has for its object a lighting device to simplify the present type.

This object is solved by the features of claim 1. Beneficial Further developments of the inventions are described in the subclaims.

In the lighting device according to the invention, the cover element consists of several cover element parts that are self-supporting and in the area of the Radiating side are arranged side by side and through the cover element parts associated fasteners with the support structure of the Lighting device are connected.
