IMAGE PROJECTION LIGHTING ASSEMBLY
A lighting assembly is provided with a housing defining a cavity that is aligned along a longitudinal axis. A light source is supported by the housing and aligned with the longitudinal axis. A lens is supported by the housing to collimate light from the light source. An image plate with a plurality of apertures formed through passes a portion of the collimated light as light segments. An exit lens includes a first series of optics arranged on a first plane spaced apart from the image plate at a first focal distance to focus the light segments at a first distance from the housing, and a second series of optics arranged on a second plane spaced apart from the image plate at a second focal distance to focus the light segments at a second distance from the housing. The second focal distance is greater than the first focal distance.
