What does headlight lens mean, the role of car headlight lens

The car lens is mainly used for xenon lamps, and the headlight lens is to add a group of optical glass lenses in front of the headlight bulb, which can make the light more focused and make the range longer, so as to achieve better lighting effects.

The role of car headlight lens

Since the light brightness of the xenon lamp is relatively high, but it is relatively scattered, it is easy to shake other cars during the driving process, and the lens has a strong light-gathering ability, and its function is to gather the scattered light into a relatively parallel beam. To put it bluntly, it is the concentrating effect. After installing the car headlight lens, the headlight line will not diverge, the lighting effect on the ground is better, and it will not affect the normal driving of the opposite car, making driving safer.

Car headlight lenses are generally divided into two types, one is a single vision lens and the other is a double vision lens. In simple terms, a single-vision lens is a lens that controls a light bulb, which is a special product. The single-vision lens is separated from far and near light; while the double-light lens is to control the angle of the shading plate inside the lens to realize the switching of far and near light. .
