Abstract
High-resolution pixel LED headlamps are lighting devices that can produce high-resolution light distribution to adapt to road and traffic conditions, intelligently illuminate traffic areas, and assist drivers. Due to the complexity of roads and traffic conditions, the functional diversity of high-resolution pixel LEDs headlamps and traffic safety has come into question and is the subject of in-depth research conducted by car manufacturers and regulators. We summarize the current possible functions of high-resolution pixel LED headlamps and analyze ways in which they could be improved. This paper also discusses the prospect of new technologies in the future.
Highlights
In the field of autonomous driving, various sensors are combined with car headlamps to reduce the occurrence of traffic accidents
Compared with the existing driver’s dashboard and head-up display (HUD), high-resolution LED pixel headlamps can project various information of the vehicle onto the car’s forward street at night, which has a warning effect, and the driver does not need to adjust the latest information of vehicles that can be obtained by sight, laying the foundation for the future development of unmanned driving
This study showed that high-resolution headlamps transmit information independently of lighting technology to enhance safety [26]
Summary
In the field of autonomous driving, various sensors are combined with car headlamps to reduce the occurrence of traffic accidents. In addition to the quasi-static low beam function, car headlamps can provide the driver with various road information [1]. Such a system is conducive to reducing the occurrence of traffic accidents while being restricted by traffic laws [2]. The main idea is to provide the best driver and road participants by changing the corresponding light distribution according to the external environmental information regarding the traffic conditions. In order to provide the best driving environment and reduce the occurrence of traffic accidents, various technologies can be used, and each form of technology has its own advantages and limitations.
