Abstract

The reflector has a sequence of annular facets, each presenting a circular edge in a plane (17) of the reflector. The plane (17) is parallel to a plane (7) of a circline lamp. The facets are oriented such that light rays reflected by them and produced by incident rays of the lamp, form maximum angle equal to a defined target angle, with rotational axis (11) of the circline lamp. An independent claim is also included for a light comprising a circline lamp and a reflector.
