What is the difference between whether there is a lens for car headlights, halogen lamps, led lamps and xenon lamps are generally used in car lights. In addition to led car lamps and xenon lamps, halogen lamps are currently widely used in new cars. It has been replaced by the other two kinds of car lights. Today, I will explain to you the difference between the lens and no lens of a car headlight.

(Led lens light dipped beam)

Bifocal lens: It is a lens that can switch between far and near light through the shading film inside the lens! When the shading plate is closed, it is the low beam, and when the shading plate is open, it is the high beam! But the light inside the lens is It doesn't move, and there is no change!

(Xenon lamp lens low beam)

1. Some are hernia headlights. It can refract the waiting light very far. And the lens headlight fluctuates with the height of the car. It will adjust the light distance.

2. The condenser type of the headlights is better after the lens is installed, and the light is brighter. Moreover, the power of the bulb used after the lens is generally small, which is good for the circuit! In car lights, the light shape of the lens lamp holder is the most standard, and there can be obvious light and dark cutting lines, which solves the problem of astigmatism. Abroad, xenon lamps are used as standard lenses. This type of lens belongs to the category of optical lenses, and we call it "lens." Compared with headlamps with traditional lamp caps, the headlights with lens-type lamp caps have the advantages of uniform brightness, strong penetrating power, and less light loss.

What is the difference between the headlights without lens? Generally speaking, the low beam headlights are equipped with lenses, and the high beam headlights do not have lenses; why? It is the most commonly used. After the low beam is equipped with a lens, the car lights will produce a very obvious light source tangent when the low beam is turned on; what is the light source tangent? Simply put, it is automatically cut off when the low beam is illuminated. The excess light retains the useful light; the excess light is the light that illuminates the driver of the oncoming car on the opposite side, and the useful light is the light that illuminates the road surface.
