STROBOSCOPIC PROJECTION DEVICE Russian patent published in 2002 - IPC

FIELD: programmed electronic- mechanical stroboscopic projection equipment. SUBSTANCE: invention is designed for volumetric-dynamic visualization of predominantly of advertising messages in the form of texts and/or pictures. Proposed device has at least one carrier of assemblage of light sources arranged over its outside surface coupled by shaft to rotation drive, control unit. All light sources are point light sources and their carrier is put on shaft and has form of rod which has shape of generating line of suitable body of revolution, thickness commensurable with cross-section of point light source and width sufficient for disappearance from field of vision of viewer with rotation. Optical axis of each point light source is oriented towards normal to generating line of that body of revolution which is specified by form of rod-carrier of these light sources. EFFECT: design of programmable stroboscopic projection device securing visualization of advertising messages with effect of their free soaring ( suspension ) in space. 15 cl, 24 dwg
