Car Light Dimming Motor Introduction

Car lights are an important appearance part and safety part of a car, and the effect on the far and low beams in the car's front combination lamp is an important part of the car's active safety. While ensuring that the light illuminates the road ahead, it must also ensure that it does not cause dazzling effects on oncoming vehicles. The front combination lamp is the most complicated in the car lamp. Generally speaking, the front combination lamp is mainly composed of high beam, low beam, turn signal lamp, position lamp and so on. Among them, the light distribution of high beam and low beam is the focus and difficulty of lamp design. In order to ensure that the headlights have sufficient illuminance and a wide enough lighting range without dazzling after loading, and at the same time, it is necessary to adjust the light deviation caused by different road conditions and different loads, which requires a car light dimming system To maintain the light pattern of the headlights after loading. The correct adjustment of the headlight light is very important. The high directivity of the beam not only affects the actual illumination effect, but also has a great impact on the driving safety of yourself and other vehicles. If the height of the headlight beam is too high, the ground cannot be clearly seen; if the height is too low, the irradiation distance is too short.



Headlamp Leveling Device dimming system can be divided into manual dimming system and automatic dimming system from the control mode; from the realization structure can be divided into screw adjustment, gear transmission adjustment, motor adjustment and adaptive adjustment (AFS) and so on. According to the requirements of the "GB4785" regulations, the manual headlight dimming device must be operated while sitting in the driver's seat. Therefore, in addition to the adaptive dimming system, there are corresponding dimming control devices in the cab to control the motors on the lamps. Make adjustments. The driver outputs different voltages to the regulating motor through the dimmer switch installed in the cab. According to its own characteristic curve and the input voltage value, the motor controls the movement stroke of the motor adjusting rod, so as to achieve the purpose of dimming.
