Warning beacon with rotating reflector

摘要

The beacon has a rotating reflector (10) behind a bulb (12). It is designed so that it generates a rotating main beam (13) from the bulb plus one or more additional rotating beams (14) at an angle ahead or behind of the main beam. The reflector has at least one additional hole (11) for these additional beams. The reflector is provided with at least one additional reflecting surface with a different focus from that of the main reflecting surface and this generates the additional beams. The strength of the additional beams is determined by the size of the holes and the design of the additional reflecting surfaces.
