This is effected by the fact that the LED due to their strip or strip-like design and their attachment to the frame of the device over a large area moistened the structured surface of the reflector film. Due to the structure of the surface while an effect is brought about, which simulates, for example, a dome-shaped or pointed roof-shaped design. This gives the viewer the impression that. In the case the attachment of the lighting device to the ceiling, a greater ceiling height than the actual room height is suggested. When the lighting device is mounted on vertical walls, an optical enlargement of the spatial depth is simulated.
