Light system having optic for use in a rearview mirror assembly

摘要

According to another aspect of the present invention, a light system for use in a rearview mirror assembly is provided and includes a light source and a first optical element. Said first optical element has a collection optic configured to direct light received from said light source, a reflector optic in optical communication with said collection optic and configured to reflect light from said collection optic, a plurality of light steering areas configured to steer light propagating in said first optical element, and a light spreading optic configured to spread light exiting said first optical element. A second optical element is in optical communication with said first optical element and is configured to diffuse light received from said first optical element to illuminate an indicia.
