Anti-dazzle system for road vehicle - has polarised head lamp lens and windscreen fitted in each vehicle

摘要

The motor vehicle is provided with headlamps polarised in one plane, and inclined 45 degrees to the horizontal. The windscreen is polarised or provided with a retractable polarised blind. The windscreen polarisation is parallel to the head lamp beam. The system is only effective if all road users are similarly equipped. The design works on the phenomena that a person looking through a polarised lens offset 90 degrees to the light plane will not see the light source.
