Abstract

An apparatus and system are disclosed and include a vehicle interior lighting system comprising that includes a light engine with a plurality of independently addressable light emitting diode (LED) segments, each independently addressable LED segment including at least one LED, a flexible printed circuit board (PCB) having a base and plurality of legs extending from the base, each leg supporting an independently addressable LED segment, and a light guide plate configured to provide illumination from the plurality of independently addressable LED segments inside the vehicle. A processor may be configured to receive information from a o vehicle sensing system, a vehicle communication system, or a detection system, and may generate a signal. A controller may be configured to provide one or more light control signals to modify at least one light characteristic of at least one of the plurality of independently addressable LED segments based on the signal.
