Design Structure of Automobile Headlight
2019-10-28 17:18:40

Single light and double light on the automobile refer to a reflector or lens, which has the function of single low beam or high beam, or both. A double lens is also a single lens. The headlights are respectively single lens low beam lamp and reflective bowl high beam lamp; single reflection bowl (integration of far and near) and double reflection bowl lamp. There is only one single low beam lamp in these two styles, and halogen bulb or xenon bulb is generally used. Through the design of the light shield inside the lens, the switching of the high and low beam lights is achieved. When the light shield is normally closed, it is a low beam light. When the dimmer solenoid valve drives the action of the light shield, it becomes a high beam light, realizing a single bulb or a single LED. There are two functions in the single lens: high beam and low beam.
