Floodlight twin reflector construction - has parabolic sections mounted around light source to reduce multiple reflections

摘要

A reflector for a lamp has a min reflector in the form of a trough of parabolic section with the light source at its focal point and with a second reflector within the first reflector in front of the light source. The position of both parabolic sections (13, 14) of the out plane of the second reflector (7) is mounted on part of the branch arm of a parabolic. The axis of this parabola is the main axis (2) of the light beam and has the emission zone (5) of the source situated at its focal point. The lamp can be mounted on a mast for floodlighting an area such as a football pitch.
