ABSTRACT:
An illumination system according to the invention has three radiating units along each longitudinal side and two radiating units along each transverse side of the illumination system. The radiating units are arranged symmetrical to the imaginary center lines in longitudinal and transverse directions of the illumination system. Each individual radiator unit at the transverse side includes a radiating source surrounded by three heat-protection filters while, in each of the three radiator units along the longitudinal side, one of the heat-protection filters is substituted by a reflector plate. The reflector plates of the left-hand and right-hand radiating sources are beveled rectangles, while the reflector plate of the middle radiating source is a rectangle without a beveled upper edge. Along the longitudinal and transverse sides of the illumination system are arranged reflectors, which consists of two reflector parts, which are detachable from each other at a separating point. The individual reflector parts consist of reflector segments which enclose different angles with one another.
