Headlight with a gas-discharge lamp

1 – gas-discharge lamp,
2 – electrodes,
3 – a glass flask with xenon,
4 – block of start of a xenon lamp,
5 – electric socket,
6 – executive engine of the proofreader of light of headlights

At gas-discharge xenon lamps intensity of lighting is more, and the light spectrum approaches a daylight range. After inclusion of gas-discharge lamps brightness of light is reached максималь by a value leg no more than in 3 seconds. Due to the bigger intensity of light and wider angle of lighting application antifog of ny headlights on the car is not required.

The gas-discharge lamp represents the glass flask filled with xenon in which two electrodes, see rice are established at a certain distance. A headlight with a gas-discharge lamp. When giving tension to electrodes of a lamp there is an arc category. For ensuring normal work of a gas-discharge lamp the electronic control unit and the high-voltage block is used. In order that formed ся the arc category, it is necessary to bring to a lamp tension about 28 000 Century. The gas-discharge lamp in relation to the 55 W of obespechiv halogen lamp ет twice big intensity of light, at the same time power of a lamp makes 35 W. Gas-discharge lamps have very big service life.

On cars with gas-discharge headlights there is a dynamic adjustment of light of headlights in the vertical plane which quickly reacts to car body inclinations.

The sensors located in a forward and back part of the car react to change of height of installation of the car. On the basis of information from sensors the control unit gives signals to executive electric motors which change the provision of reflectors of headlights. At the same time constant and uniform lighting of the road at the movement of the car is provided. Manual correction of light of headlights is not provided. If there is a defect in system of adjustment of range of light of headlights, light of headlights is established in the lowermost situation.
