Design and Simulation Investigation of 3*9 LED Matrix Headlamp to Realize Anti-Glare Function

Abstract

The core of driving is vision, drivers need to obtain information ahead based on vision to make decisions, and lighting quality directly determines the perceptual quality of drivers at night. Glare can cause temporary visual perception disability, which brings great danger to driving safety. In this article, we propose a 3*9 LED matrix headlamp which is symmetrically arranged in front of the vehicle to realize anti-glare function, along with its optical design and anti-glare control algorithm including deep learning algorithm, design positioning algorithm and control logic. 3*9 matrix layout can retain more of the illumination of the scene in front after realizing the anti-glare function than single-row layout. Left-right symmetrical layout can maximize the field angle of the lamp lighting and avoid blind areas. It has been proved that the system can well identify the vehicles in front and close the corresponding zones, realizing the anti-glare function while retaining non-glare component of lighting to the maximum extent, improving the safety of driving at night.
