Publication number: 20230089281Abstract: The present disclosure is directed to projection devices that can project patterned light of different colors. In one implementation, the projection device can include a housing, within which reside multiple components. These components can include light emitting diodes (LEDs), a parabolic mirror reflector, a sinusoidal lenticular diffuser, and multiple spatial filters. The multiple LEDs can be provided in at least two distinct colors. The parabolic mirror reflector can be arranged to collimate light received from the multiple LEDs. The sinusoidal lenticular diffuser can be positioned at an output of the parabolic mirror reflector and arranged to diffuse the collimated light. The spatial filters can be arranged to diffuse the diffused and collimated light received from the sinusoidal lenticular diffuser. An imaging lens can be coupled to the housing and arranged to magnify the diffused light received from the spatial filters and display a cloud-like effect on a first surface.Type: ApplicationFiled: August 8, 2022Publication date: March 23, 2023Inventor: Randy E.
