Vehicle lamp system based on PBS (polarization beam splitter)

A vehicle lamp system based on a PBS (Polarization Beam Splitter), comprising a light source (1), the PBS (3), a collimating lens set (2), an imaging lens set (5), an LCOS (Liquid Crystal on Silicon) control chip (4) and a light path control unit (6), wherein:

• the collimating lens set (2) and the PBS (3) are successively arranged along a light emission direction of the light source (1);
• the LCOS control chip (4) is arranged at a light path of an S wave (11) reflected by a contact surface of the PBS (3);
• the imaging lens set (5) is arranged at an emergent light path of the S wave (11) after being modulated by the LCOS control chip (4) and transmitted through the contact surface of the PBS (3);
• the light path control unit (6) is arranged at a light path of a P wave (12) transmitted through the contact surface of the PBS (3);
• and the light path control unit (6) is vehicle lamp components, comprising a mirror (7), a light shield (8) and a magnifying glass (9).
