Problems solved by technology

[0002] At present, the headlights of automobiles are divided into high beam + low beam. The high beam is for the driver to better recognize the road conditions ahead of the vehicle on the expressway, but its illumination also seriously affects the sight of the opposite driver, which is likely to cause traffic accidents.
Not only that, but in the state of following the car, it will also dazzle the vehicle in front and affect driving safety
Although the current car headlights are illuminated in the way of low beam + high beam, in order to avoid dazzling the driver caused by illuminating the vehicle in front, usually the angle of illumination of the low beam is low, and the driver switches to the low beam when there is a vehicle coming from the opposite side. Low beam, although the low beam will not affect the driver of the other vehicle, but due to the low irradiation angle, it has the defects of short irradiation distance and narrow irradiation width, which affects the irradiation effect to a certain extent
And in fact, many drivers will not 100% consciously and actively switch to low beam when meeting cars, which has a great impact on the safe driving of vehicles
Ordinary low beam irradiation width is not enough. On some rural roads with poor lighting, there will be blind spots when the vehicle turns, and the vehicle is easy to bump into other objects or pedestrians when turning
