Decorative projection light assemblies, systems, and methods

Abstract

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.
