Question about Car Audio & Video
Headlights, there is a requirement for switching between a high beam and a low beam, and two principal systems are used for this purpose.
One of these utilized a sealed beam type lamp in which two light sources are provided in conjunction with a reflecting mirror. When one of these light sources is operated, the low beam is generated, and when the other light source is operated or both light sources are operated at the same time, the high beam is generated. In this type lamp the beams are switched by switching the light sources.
In the other system, one light source is utilized with a reflecting mirror. The beam is switched by rotating the reflecting mirror or the light source, itself, upward and downward.
This invention relates to the latter system, the problems of which are discussed below.
In headlights which switch between low beam and high beam, the downward attitude of the reflecting mirror when the low beam is lit must be controlled with great accuracy to avoid blinding oncoming traffic. Previously, a vertical aiming bolt and a surrounding coil spring have been used to control the attitude of the reflecting mirror in the vertical direction. This bolt acts as a stopper, which controls the downward attitude position of the reflecting mirror. In addition, the spring is designed to permit the rotation of the reflecting mirror to allow upward rotation. Moreover, an actuator is used to make the reflecting mirror rotate upward and downward. Hitherto, solenoid systems, compressed gas systems, or motor drive systems have been used as actuators. the ball and socket assembly has particular alignment settings.if not familiar with this then its advisable to get it done by local car garage technician, This will help.
