Abstract (en)
System for the automatic cleaning of screens of electric lighting, which is composed of: a) a unit composed by a light emitter (1), a reflector (2) that projects the reflected light, and a screen (3), which is larger in diameter than the reflector (2), and the said unit is attached to a motor/reductor by the end (5), b) a group of brushes (6), also joined to the motor/reductor by the end (7), c) a regulator mechanism (8) that acts on the motor/reductor and on the light emitter (1). The whole unit can rotate on itself, and can make a certain number of turns, and during that rotation movement the exterior surface of the screen (3) coincides with the brushes (6), which can also rotate on themselves.
