Headlights
By car Golf III / Vento as light sources use a variety of halogen lamps, which have, compared to conventional lamps, a large light output and long life. The main parts are incandescent lamps, reflector and diffuser. The reflector inside covered with special heat-resistant varnish, on which a thin layer of aluminum, creating a mirror reflective surface. The reflector is a parabolic mirror that reflects and focuses the light. According to government regulations, passing beam must have a special form - with asymmetric boundary of light and dark areas in which the maximum value is concentrated on the right side of the roadway. To meet these standards, a special lens is made of glass and has, on the inner side of a cylindrical lens, a prism and a plane parallel to that divert the reflected light reflector in a desired direction. In addition, the car is equipped with an adjustment of the angle of the optical axis of the headlights. This system should prevent blinding oncoming drivers with a loaded vehicle. The car Golf III / Vento each lamp has a servomotor - stepper motor which rotates the movable reflector around the lamp axis to the desired position and thereby the tilt axis of the headlights. Starting position lights on the switch is indicated by the number "0". The maximum angle of inclination of the optical axis washers marked "3". Once a year, you need to check the efficiency of the system adjust the angle of the optical axis of the headlights.
