What is The Principle of Automobile Headlight Lens?

Automotive lamp lens is the headlamp light gathering method, lens headlamp is a smaller, more compact structure of the small spotlight cup will be light gathered into a beam of parallel light, and then through the convex lens dispersed into fan-shaped light. Automotive lenses are mainly used for xenon lamps, while the headlight lens is to add a set of optical glass lenses in front of the headlight bulb, which allows the light to be more focused, so that the range is farther, which in turn achieves a better lighting effect.

Lens headlights principle is as follows:
1, because the lens has a strong ability to focus the light, so use it to illuminate the road, not and the road is bright and clear; in fact, it is said that the headlights a way to focus the light. Traditional headlights are a bulb with a shiny shade, this shade is called a spotlight shell, flashlights also have such a cover, the principle is the same;

2, because the light dispersion is very small, so its light range is farther and clearer than ordinary halogen lamps. Therefore, it enables you to see things in the distance at the first time, avoiding driving through the intersection or missing the target; this lampshade will form a fan-shaped beam of light from the bulb, thus illuminating the road in front of you, while the lens headlamps use a smaller, more compact, small spotting cup to gather the light into a beam of parallel light, and then dispersed into a fan-shaped light through a convex lens;

3, the main components of lens headlamps are: bulb mounting bracket, spotlight cup, convex lens, far and near light electromagnetic coil and baffle plate. Lens headlights compared to the use of traditional headlights headlights have, uniform brightness, strong penetration, so he whether in the rain or in foggy weather has a strong penetration. In turn, it can make the oncoming vehicles receive light information for a short time to avoid accidents.
