<p>Mechanism for indicator beacons with rotating light beams, consisting of: - a motor 1 with a rotating shaft having a vertical axis; - a parabolic reflector 2, which focuses the rays of light emitted by a lamp 4 into a beam of parallel rays directed upwards; - a flat elliptical mirror, fixed to the motor shaft at an angle of 45 degrees, which causes the rotation of the beam of parallel rays sent from the underlying parabolic reflector. <IMAGE></p> |
