HID xenon bulbs have greater light intensity and spectrum of light is close to the spectrum of daylight. After turning on the light intensity discharge lamps reaches maximal values by no more than 3 seconds. In connection with the greater intensity of light and a wider angle of illumination does not require the use of fog lights GOVERNMENTAL car. The gas discharge lamp is a glass bulb filled with xenon, which are installed at a certain distance the two electrodes, see. Fig. Headlamp with gas discharge lamp. When voltage is applied to the electrodes of the lamp arc discharge occurs. To ensure the normal operation of a discharge lamp using an electronic control unit and high-voltage unit. In order to form a smiling arc, it is necessary to bring to the lamp voltage of about 28 000 B. Discharge lamp with respect to the halogen lamp output of 55 watts is providing twice the intensity of the light, while the lamp power is 35 watts. Discharge lamps have a very long service life. On vehicles with HID headlamps has a dynamic adjustment of headlights in the vertical plane, which quickly react to the inclination of the car body. Sensors located in the front and rear of the vehicle, responsive to a change of height of installation of a vehicle. Based on information from the sensor control unit transmits signals to the executive electric motor that change position reflector headlights. This ensures a constant and uniform illumination of the road when driving. Manual adjustment of headlights is not provided. If there is a defect in the LDR headlights, headlights installed in the lowest position.
