A Preliminary Anti-Glare System for Traffic Vehicles Using Polarizing Filters and a Polarizing Flip Plate

In the past, polarizing filters were attached to cars’ halogen headlights to reduce glare for other vehicles. However, the filters absorbed a significant amount of light and made it difficult for drivers to see properly. Coupled with overheating issues and numerous technical and logistical limitatio...

Description
Summary:In the past, polarizing filters were attached to cars’ halogen headlights to reduce glare for other vehicles. However, the filters absorbed a significant amount of light and made it difficult for drivers to see properly. Coupled with overheating issues and numerous technical and logistical limitations, polarized automotive lighting systems have not become widespread. In this research, we propose using a polarized LED lighting system to improve drivers’ visibility. Our results demonstrated an illuminance reduction of up to 97.5% when simultaneously using a polarized headlight filter and flip plate. Additionally, our system’s lower operating temperatures resulted in a lifespan increase of approximately 120 times compared to a conventional halogen lighting system.
