Reflector for in-cabin monitoring systems

A rearview mirror assembly comprising:

• a primary housing including an upper edge and a lower edge spaced from the upper edge by a pair of side edges;
• a glass element coupled to the primary housing and defining a viewing surface;
• a first printed circuit board (PCB) located, at least in part, in the primary housing;
• and
• a monitoring system comprising:
• an image capturing module;
• a first set of illuminators connected to the first PCB proximate one of the pair of side edges and a second set of illuminators connected to the first PCB proximate one of the pair of side edges opposite the first set of illuminators;
• and
• a first reflective element located between the first set of illuminators and the upper edge of the primary housing and a second reflective element located between the second set of illuminators and the upper edge of the primary housing, the first and second reflective elements configured to redirect and spread an infrared illumination from the first and second set of illuminators within an interior cabin of an automobile.

A rearview mirror assembly comprising:

• a glass element coupled to the primary housing and defining a viewing surface;
• a first printed circuit board (PCB) located, at least in part, in the primary housing;
• and
• a monitoring system comprising:
• an image capturing module;
• at least one illuminator connected to the first PCB and facing a direction of the viewing surface;
• and
• a reflective element proximate the at least one illuminator, the reflective element located between the at least one illuminator and the upper edge of the primary housing and including a top element surface and a bottom optical surface, the bottom optical surface defining a reflective segment facing the at least one illuminator, the reflective segment defining a non-planar shape including a plurality of optical pillows that redirect and spread a light from the at least one illuminator towards a lower region of a vehicle cabin.
