Abstract (en)
[origin: WO0115408B1] A stroboscopic display device has at least one carrier, associated with a rotary drive shaft, to carry a plurality of point light sources arranged externally on said carrier, and a control unit to cut in and out said light sources. To display advertising messages with the effect of free hovering in the air, the carrier is formed as a rod shaped correspondingly to an appropriate revolution body generatrix and cantilevered onto the drive shaft; the rod thickness commensurable with the cross-section of a point light source, and the rod width sufficient to illusorily disappear from the spectator vision field during gyration. The optical axis of each light source is perpendicular to the revolution body generatrix defined by the carrier shape.
