Abstract: A projection light assembly is provided which achieves a multi-theme animation effect. The assembly includes a main mount board, at least one laser light source coupled to the main mount board, a grating group platform rotatably coupled to the main mount board, at least one grating group mounted to the grating group platform, a motor coupled to the main mount board and/or the grating group platform, and a motherboard in communication with the laser light source, the grating group, and the motor. Light generated by the laser light source is transmitted in a light path and projects through the grating group, and the motor drives the grating group to rotate through the light path. Methods of manufacturing a projection light assembly are also provided.

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.
