Today almost all the world's leading automakers, at the plant, install xenon light as the vehicle's standard equipment. This is a fundamentally new technology of light, based on the glow of an electric arc formed when an electric current passes through the gas medium. Installation of xenon light is gaining increasing popularity among motorists. This phenomenon has a logical explanation, xenon lamps are economical and durable. Xenons, in contrast to halogen lamps, are not afraid of voltage fluctuations, have a much longer life, half the current consumption, reducing the load on the generator, and due to the high brightness and intensity of xenon light, the road illumination improves by 40%, the zone increases and angle of view, even in poor visibility. Light xenon lamps in its range, which is as close to natural, daylight, is comfortable for the driver and passengers. A pleasant lighting with visual perception, it's safety and comfort. Xenon lamps are a high-pressure gas discharge light source that operates using the principle of a light arc. A sealed, gas-discharge bulb made of quartz glass, filled with mercury vapor and a mixture of inert gases, one of which is xenon. In order to light the xenon lamp, it is necessary to apply a voltage of 25000V, and the working, constant voltage must be maintained at a level not lower than 80V. Bi-xenon lamps. Unlike conventional xenon, differ in the design of the socle and the presence of special wiring. To combine the near and far light in one headlight, the lamp has a movable flask that is used in both low and high beam driving modes. When switching from near to the main beam, the focal length of the headlamp light changes. LED-lamp. A modern LED for car headlights, a semiconductor element that emits light through a current. Such LEDs light up faster than ordinary bulbs, they are resistant to vibrations, and consume significantly less energy, and when used, factory wiring is used.
