Abstract

Reflector comprises a light source, a light conductor(s) and a reflector producing light radiation. The reflector is in a central position and there is a light closure in two right angle axes which is much longer in one axis than the other. Preferably the light conductor is glass fiber, polycarbonate and/or polymethyl methacrylate and the light source is an LED.
