Patent ID: 7018071

Claim:
A light apparatus producing a central motionless light beam and at least one beam rotating around the central beam, comprising: a housing; a lamp with a reflector; a rotating non-transparent disk having a central round opening and having at least one non-central opening, and said disk is placed within said housing, in front of said lamp with reflector, and said disk is placed perpendicularly to optical axis of said reflector so, that the center of said central round opening in said disk lies on optical axis of said reflector, and, when said disk rotates, at least one said non-central opening produces at least one light beam rotating around central motionless beam which is produced by said central round opening; a ball-bearing having an inner mobile metallic ring and having balls, separators and an outer fixed ring of electro-insulating material or materials, and said ball-bearing is placed within said housing, and said disk is mounted in said inner ring, and said disk rotates together with said inner ring which is rotated by a rotating magnetic field; and an inductor-stator for creation of said rotating magnetic field, and said inductor-stator is supplied by polyphase alternating current, and said-inductor-stator is placed between said outer ring of said ball-bearing and said housing, and said outer ring is mounted to said inductor-stator, whose base is mounted to said housing.
