Abstract
In automobiles, the headlights are rapidly developing part by new technologies. In particular, it is a technology categorized as the ADB (Adaptive Driving Beam) that prevents glare by operating High Beam at night and turning of a portion of the lighting depending on the circumstances surrounding it. The HBA (High Beam Assist) was the first technology in the ADB. When a car finds another one around it, the headlamps are converted from high beam to low beam. GFHR Glare Free High Beam) is operates the mechanical shield to make the part dark. It has even been developed to create a Matrix-Beam that creates a variety of patterns by lighting individual LEDs. In order to control the Matrix Beam more precisely, the Micro LED is a smaller size than a fingernail and comprises more than 100 LEDs. And there is Pixel-light, which is expected to be the pinnacle of the headlamp technology. Control millions of small areas to prevent glare from neighboring vehicles. It also created another feature on the exterior lights of the vehicle.
