Abstract
A device (100, 200, 300, 400, 500) including an ambient image light source (110, 210, 310) and a stacked plurality of ambient imaging light guides (120, 220, 320) The ambient image light source (110, 210, 310) is arranged to couple light into the stacked light guides (120, 220, 320). The stacked light guides (120, 220, 320) are arranged to couple out corresponding ambient image light portions onto a reflective surface (130, 230). The stacked light guides (120, 220, 320) may be arranged to provide the ambient image light portions extending outward from the device (100, 200, 300, 400, 500) such that a first one of the ambient image light portions extends substantially outward from a second one of the ambient image light portions. The second one of the ambient image light portions may be projected closer to the device (100, 200, 300, 400, 500) and may be projected to reflect brighter than the first one of the ambient image light portions.
