In all kinds of car headlights, if you look carefully, the headlights of the car are the same as the big steel balls with bumps. Some cars have nothing, but they seem to be similar when used. Is that really the case? Everyone said that the situation, and the people who know and the people who do not understand have their opinions, and they do not know what to do. So they have an idea, write a professional car lens knowledge, gather personal understanding of it, and step on the use of the modification process. The thunder and pit, I hope to help everyone.
The role of the headlight lens
Reflecting the scattered light of the bulb into a parallel beam, the luminosity is greatly enhanced, enhanced by hundreds or even thousands of times. Ensure adequate lighting in the 150-400M range in front of the car. The translucent mirror acts to refract the flat beam reflected by the mirror; there is a clear line of light and dark. In actual use, the lens has a strong concentrating ability. As long as it is properly installed on the headlight, it can be clearly illuminated. Bright road surface, and the light can show the effect of left low right height. Under the high beam and low beam, the light will not diverge, but the lighting effect on the ground is very good, it will not cause glare, and will not affect the normal of the opposite car. Driving, this lens is commonly used in various front and low beams.
Type of lens
The types of lenses of automobiles are divided into two types: single-lens lenses, one-type single-lens lenses, and single-lens lenses. In simple terms, a single lens controls a light bulb, which belongs to a unique product. The single-lens lens is separated by light. The double-lens lens is a light-shielding film inside the lens, which can switch between far and near light! When the light-shielding film is closed, it is low-beam, when the light-shielding film is open, it is high beam! But the light bulb inside the lens is not There is no change in the movement!
What is the difference between mounting a lens and not wearing a lens?
In general, careful observation will reveal that the car is a low beam with a lens, and the high beam is not. For the purpose of design, the low beam is the most used. In the urban road, the high beam is basically not used. After the lens is attached to the lens, the light is particularly concentrated, and there will be obvious tangent. If you look at the opposite side, there will be no glare. If you don't have a lens, the light is very scattered and looks glaring. So there is a fundamental difference between installing a lens and not mounting a lens.
