  • The difference between lens and without lens for head light
    Nov 23, 2018

    The lens is mounted in the headlight assembly, a convex mirror like a magnifying glass, and there is a glass ball with a big eye in the headlight. If there is no headlight, it is not installed. Look directly at the appearance of the lights, as shown in the light group, the middle low beam is lensed, and the inner high beam is lensless.

    The role of the 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. Light Mirror Effect The flat beam reflected from the mirror is refracted to provide a good and uniform illumination of the road surface in front of the vehicle. In the high beam and low beam conditions, 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 driving of the opposite car. This kind of lens is commonly used in series. The installation of a dual-lens lens means that a xenon bulb has two functions of high beam and low beam.

    Dual-lens lens classification single-lens lens: there is only one light - low beam, generally using halogen bulbs or xenon bulbs. The single-lens lens is separately designed with a lens corresponding to the low beam and the high beam. The difference between the two-lens lens is that it can be converted into a near-far and near-light conversion, and is usually in a low beam state. Double lens: It is a lens that can switch between far and near light through the light shielding film inside the lens! When the opaque film is closed, it is a low beam. When the opaque film is opened, it is a high beam! But the light bulb inside the lens is not moving, and there is no change!

    What is the difference between a car headlight and a lens? Some are Xenon headlights. The light can be refracted very far. Moreover, the lens headlights fluctuate with the height of the car. It will adjust the light distance. 2. After the lens is installed, the headlights have better concentrating type and the brighter the light. Moreover, the lamp used after the lens is generally installed has a small power, which is good for the line! In the automobile lamp, the light shape of the lens base is the most standard, and there is a clear light and dark cutting line, which solves the problem of astigmatism. In foreign countries, xenon lamps are used as standard lenses. These mirrors belong to the category of optical mirrors. We call them "lenses". The headlights with the lenticular head have the advantages of uniform brightness, strong penetrating power and small loss of light compared to the headlights using the conventional lamp head.


    What is the difference between a headlight with a lens and a headlight? In general, the low beam has a lens and the high beam has no lens; why? Because the low beam is the most commonly used in urban roads, after the low beam is attached to the lens, the light will produce a very obvious light source tangent when the light is turned on; what is the light source tangent? Simply speaking, when the low beam is illuminated, the excess light is automatically cut off, and the useful light is retained; the extra light is the light that illuminates the driver on the opposite side, and the useful light is the light that illuminates the road surface. Explain that the first picture below shows only the low beam

    Everyone understands that the lens of the low beam has a very obvious source tangential line. The advantage is that on the city road, only the light can be turned on, but the light is not on the opposite side. The driver's cab went to the driver's line of sight to avoid unnecessary safety incidents.
