Automobile headlight structure information, also known as illuminator, is the focus of all lights in the entire vehicle and is the heart of the vehicle. Reasonable use of headlights should be such that it turns into a low beam when meeting cars, and back to high beams in time after meeting cars. When passing an intersection and overtaking, it should be indicated by changing the far and near beams.

So how exactly are the headlights formed? If the headlight assembly is dismembered, it can be roughly divided into several parts such as a hood, a reflector, a lens, and so on. (The following introduction is closed headlamp)

1. Car headlight structure-hood

A hood (shading plate) is equipped in front of the filament in the vacuum wick. Its function is to block the upward direct light when the filament is on. If this part of the upward light from the headlight of the car is not blocked, it will cause severe dazzling of the drivers of oncoming vehicles, and these scattered lights will also form a light curtain in front of the car in rainy or foggy environments, making the car The visibility of the driver is reduced.

2. Car headlight structure-reflector

Most of the enclosed vacuum wick reflectors are parabolic surfaces formed by parabolic rotation. In the production process of the reflector, the aluminum is evaporated and coated on the inner surface by a vacuum coating process. It has extremely high brightness, and the reflected light brightness can be increased by more than 6000 times than the brightness of the filament itself.

3. Car headlight structure-light lens

It protects the entire headlight assembly. The light beam formed by the light source of the car headlight through the reflector is difficult to meet the requirements of the headlights of the regulations, and the light distribution mirror is required to change or widen the light beam. Or narrow it to form the required lighting in front of the car. This function is accomplished by the headlight lens (headlight glass). The headlight lens is composed of many small prisms with unevenness. It can refract and scatter the light reflected by the reflector to make it meet the light distribution requirements of the headlight. At the same time, it also diffuses a part of the light to both sides to widen the illumination range of the headlight in the horizontal direction, and get The desired light distribution effect. There are also car headlights that only rely on the special structure, complex shape and high processing accuracy of the reflector to meet the light distribution requirements, but the design, calculation and mold accuracy and processing technology of the production of this reflector are still very difficult. of.

The illumination effect of the light also depends on the illumination angle to a certain extent, and the light adjustment device can exert its maximum potential.

4. Car headlight structure-where does the water in the car headlight come from。

Look at the structure of the headlights, and then take a look, in fact, there is a lot of moisture in the air, and this is closely related to the water vapor formed in the headlights. At this time, your question is coming, isn't the entire lampshade sealed? How can moisture in the air get in?

The lampshade as a whole is indeed sealed, but this does not mean that the inside of the lampshade can be isolated from the world like a vacuum packaging. After all, future repairs must be taken into account. Furthermore, when the lamp is lit, a large amount of Heat, so from the perspective of heat dissipation, there will be a hand on the lampshade.

Some headlights will be equipped with a ventilation hole at the back, but this ventilation hole will not be exposed naked, and may be treated with a rubber ventilation tube. It is through this ventilation tube that the headlight is lit. The heat can be discharged, so that the lights are always in a relatively stable environment. It is also this ventilation pipe that the moisture in the air can enter the interior of the headlight and be adsorbed on the surface of the lampshade. When it accumulates to a large scale, it will flow down from the lampshade in the form of water droplets.

Summary: Light bulbs with different functions have different specifications. Even if the function is the same, the types will be different; the lamp holders are comparable, because different types of lamp holders mean different series of bulbs for manufacturers. product. The above is all relevant information about the structure of the headlight of the car。
