What is the car of the lens

---------   [ 2015-05-25 ]

Headlight lenses can be divided into two types: single-lens, bifocal lens. Single-lens: there is only one light beam ------ general use halogen bulbs or xenon bulbs. Bifocal lens: a lens through internal shading lenses, you can achieve the distance light switch! When closed shading film, the last light, when gobo open when it is far from the light! But the lens inside the bulb is not moving, and no change! Installed bifocal lens is to achieve a xenon bulb played two roles in the low beam.

A friend to ask: What is directly mounted xenon bulbs can not it do? As the car is not equipped with a lens headlight assembly, after the installation of HID, traditional halogen lamp shade can not play a role in the condenser, the lighting effects discount does not say, out of the light will certainly diverge, resulting in dazzling effect, but also seriously affect the normal running across the car, the security risk is enormous. The installation of a bifocal lens effect: Under beam, the state near the light, the light will not diverge, but the ground is very good lighting effects and will not cause glare, will not affect the normal running across the car, this lens is generally used.
