Abstract (en)
Device for the variable deflection of a light beam, particularly for floodlights, comprising a frame (1) which can be mounted on a floodlight (2); the frame has a fixed part (3b) and a movable part (3a). The movable part is rotated with respect to the fixed part by first transmission means and supports a first mirror (4) and a second mirror (5). The first mirror crosses the light beam which leaves the floodlight and is inclined with respect to the direction defined by the light beam, whereas the second mirror is spaced from the first mirror and is inclined with respect to the light beam which leaves the first mirror. The second mirror is rotatable with respect to the first mirror. <IMAGE>
