An image projection system (10) having a projector (12) having an interchangeable optical slide holder (14) configured to adaptively focus an object slide (20) onto a surface (16, 42) of a vehicle (17). The system includes an image management system (18) associated with the projector. The image management system is for selectively associating one object slide at a time with the interchangeable optical slide holder for projection of the selected object slide (20a) upon the surface.

A dynamic film projector includes a driving mechanism having two rotation shafts parallelly extending upwardly, and a first projection assembly and a second projection assembly arranged side by side on the driving mechanism. At lease one of the first and the second projection assemblies includes: a light source, a lens assembly arranged in front of the light source, a dial having a shaft extending downwardly from a center thereof and several films fixed on the dial. The shafts connect the two rotation shafts of the driving mechanism. Lights from the one or more light sources are capable of passing through the one or more films and the lens assembly in sequence when the dial is driven by the driving mechanism to rotate. Along with continuous rotation of the dials, the patterns on the films are projected in sequence, so that the effect of continuous animation is realized.

The invention provides an outdoor projector device for generating a patterned light output, the patterning of the light being achieved at least partly by means of a rotatable beam patterning element being mechanically driven by means of a mechanically coupled wind turbine element.

A laser projection device has at least one laser light source and a plurality of gratings, each grating having a light receiving side and a light emitting side. The plurality of gratings are arranged in a ring-shape having at least one row with the light receiving side of each grating facing a center of the ring. The laser projection device also has a motor configured to rotate the plurality of gratings about a rotational axis passing through the center of the ring. The plurality of gratings each comprise a pattern for forming an image when light is passed through the pattern. The plurality of gratings are arranged around the ring such that the plurality of patterns are configured to project an animated image when the plurality of gratings sequentially receive light from the at least one laser light source upon rotation of the grating set.

A projection device for projecting images on a surface of the device includes an outer housing having a front translucent screen, a projection module frame mounted on an inner surface of the outer housing, and a projection roller frame supported by the projection module frame. The projection roller frame includes first and second spaced apart rollers rotatable respectively on two opposite cylindrical ends integrally formed on a lampshade. A cylindrical projection film is held between the first and second rollers. A light source is mounted inside the lampshade so that an image formed on the projection film can be projected on the front translucent screen by the light source. The device further includes a gear mechanism for driving the rollers, a position-limiting mechanism, and a speaker.

A device for projecting an image on a projector module screen, comprising an interchangeable disc including at least one image disposed thereon and a light source for illuminating the at least one image. The device further includes a lens for receiving the at least one image from the interchangeable disc and passing the image to the projector module screen, wherein the projector module screen displays the image and a projector module housing enclosing the interchangeable disc, the light source, and the lens.

A rotatable stroboscopic animation device with a rotatable base portion and at least one light source. An angular-velocity-dependent flashing system flashes the at least one light source according to a predetermined flash mode dependent on the angular velocity of the base portion to produce coherent, automatic stroboscopic animation of images retained by the base portion. The flashing system can comprise an angular velocity determination system in cooperation with an illumination system. Angular velocity can be determined by an orienting system, such as a compass, in combination with a sampling system, a gyroscope, or a rotational sensor. A flash mode selection mechanism, which can be manual or automatic, permits a selection of a flash mode from among a plurality of flash modes. A manual flash mode selection mechanism can be formed by relatively pivotable upper and lower disks of the base portion. Animation disks can have indications of predetermined flash modes.
