13.20. Gas-discharge lamps of headlights of a passing light

Headlight with a gas-discharge lamp

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

Gas-discharge xenon lamps have more intensity of illumination, and light spectrum comes nearer to a daylight spectrum. After inclusion of gas-discharge lamps brightness of light reaches максималь ного values no more than in 3 seconds. In connection with большей intensity of light and wider corner of illumination application противотуман ных headlights on the car is not required.

The gas-discharge lamp represents the glass flask filled ксеноном in which two electrodes are established on certain distance, fig. the Headlight with a gas-discharge lamp see. At pressure giving to lamp electrodes there is an arc category. For maintenance of normal work of a gas-discharge lamp the electronic control mean and the high-voltage block is used. That has formed ся the arc category, it is necessary to bring to a lamp pressure about 28 000 V.Gazorazrjadnaja a lamp in relation to галогенной to a lamp capacity of 55 Vt обеспечива ет twice the big intensity of light, thus capacity of a lamp makes 35 Vt. Gas-discharge lamps have very big service life.

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

The gauges located in a forward and back part of the car, react to change of height of installation of the car. On the basis of the information from gauges the management block submits signals to executive electric motors which change position of reflectors of headlights. Constant and uniform illumination of road at car movement is thus provided. Manual updating 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 position.
