Abstract

Dispositivo di deviazione variabile di fascio luminoso particolarmente per riflettori, il quale comprende un'intelaiatura montabile su un riflettore; l'intelaiatura presente una parte fissa ed una parte mobile. La parte mobile viene posta in rotazione rispetto alla parte fissa da primi mezzi di trasmissione e sostiene un primo ed un secondo specchio. Il primo specchio intercetta il fascio luminoso fuoriuscente dal riflettore ed è inclinato rispetto alla direzione definita dal fascio stesso, invece il secondo specchio è distanziato del primo specchio ed è inclinato rispetto al fascio luminoso proveniente dal primo specchio. Il secondo specchio è ruotabile rispetto al primo specchio.Variable beam deviation device particularly for reflectors, which comprises a frame which can be mounted on a reflector; the frame has a fixed part and a moving part. The moving part is rotated with respect to the fixed part by first transmission means and supports a first and a second mirror. The first mirror intercepts the light beam coming out of the reflector and is inclined with respect to the direction defined by the beam itself, instead the second mirror is spaced apart from the first mirror and is inclined with respect to the light beam coming from the first mirror. The second mirror is rotatable with respect to the first mirror.
