Description
Technical Field
The invention belongs to the technical field of automobile light control, and particularly relates to a vehicle light control system with a combined headlamp function.
Background
The headlamp is a lamp for illuminating the road ahead when the automobile runs at night, and is one of important parts for ensuring the safe operation of the automobile. The farther the illumination distance of the headlamp is, the better the light distribution performance is, and the higher the safety performance of the automobile in running is.
The automobile headlamp emits two light beams of high beam and low beam, wherein the high beam is on a road without a vehicle coming from the opposite side, and the automobile runs at a higher speed. The high beam should ensure bright and uniform illumination on a road surface 100m or more in front of the vehicle. The far and near light lamp is used for night illumination, but the far light angle is high and the distance is far, and the near light angle is low and the distance is near. The high beam can improve the sight and enlarge the observation visual field. On a painted black road surface without a street lamp, the visible range after the high beam is turned on is far larger than that after the low beam is turned on; the dipped headlight is used for short-distance illumination, the design requirement is that the illumination range is large (160 degrees), the illumination distance is short, the concentration degree cannot be adjusted, and the illumination distance of the dipped headlight is about 30-40 meters; the position lamp is used for displaying the position of the stationary vehicle in the dark, and the lamp light provided by the position lamp function enables people behind to see the vehicle under low light or at night. Because the position light function operates at night or in low light, the position light function requires a relatively low light output to be seen; in addition to providing the necessary lighting functions, vehicle designers have attempted to make the light assemblies as aesthetically and optically homogenous as possible, which has also led to the design of currently popular combination vehicle lamp lighting solutions.
