A projection light assembly is provided which achieves a multi-theme animation effect. The projection light assembly includes a gear holder, a first gear and a second gear operably linked by the gear holder, a motor coupled to one or both of the first gear and second gear, a grating unit holder movably connected to one or both of the first gear and second gear, and a grating unit mounted to the grating unit holder. The grating unit is driven by the motor and moved by the first gear and second gear such that the grating unit moves circumferentially in a fixed radius. At least one laser light source is positioned such that light generated by the laser light source and transmitted in a light path projects through the grating unit. A transmission belt may be coupled to the first gear and the second gear, and the grating unit is driven by the motor and moved by the transmission belt. A projection light assembly may include a slider board a motor coupled to the slider board, an eccentric wheel coupled to the motor, a laser slider disposed in the slider board, and a grating unit disposed in the laser slider, wherein the grating unit is driven by the motor and moved by the eccentric wheel.

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 telescopic projector has a body, a projecting set, and a focusing set. The body has a shell and a roll film. The roll film is mounted in the shell. The projecting set is mounted in the body and has a power supply board and a radiating unit. The power supply board is located in the shell. The radiating unit is located in the shell and is electrically connected with the power supply board. The focusing set has a focusing electric machine, a driving block, and a sliding unit. The focusing electric machine is mounted in the shell and is electrically connected to the power supply board. The driving block is mounted on a top surface of the focusing electric machine and is controlled by the focusing electric machine. The sliding unit is mounted in the shell and is located above the focusing electric machine.

A projector has a body, a rotating device, a projection device, and a supporting device. The body has a lower housing, an upper housing, and an operation chamber. The rotating device is mounted in the operation chamber, is located in the upper housing, and has a driving device, a rotating axle, a power supply circuit board, and a film base. The projection device is mounted in the operation chamber of the body and has a light unit, a Fresnel lens, a film holder, and a lens assembly. The supporting device is mounted on a bottom of the lower housing.
