The present invention relates to an omnidirectional reflector having a light source situated in the center thereof, said reflector being adapted to project a light distribution giving a generally even illumination on the plane under the reflector. This reflector is composed of a number of segments of reflector material which are arranged around the light source and turned helically in the vertical sense of the reflector, said segments at least substantially enclosing the light source and forming a symmetrical body. |
