The principle of operation of xenon car lamps

When choosing a car light, the driver often has to think about which type of lamp is best suited for his car. One of the most popular are xenon lamps. They are especially so that they work stably in all conditions and produce a powerful, precisely directed luminous flux that can illuminate the space in front of the car very well.

Design features of xenon car lamps

Xenon automotive bulbs were specifically designed as high-brightness light sources. They give out a high-intensity light flux, which is formed due to the xenon gas emission provoked by an arc discharge passing between two electrodes. The light output of this type of lamp can reach 80 lm/W, this is several times higher than the halogen counterparts.

Their design is quite simple. The electrodes are placed in a special flask filled with xenon-based gas mixture and metal salts. The gas is under high pressure (inoperative 30 atmospheres, and in combustion mode up to 120 atmospheres). The xenon lamp usually has two flasks (internal and external). Internal is just used as a gas tank a mixture.

A special feature of these lamps is that a special high-voltage unit (control unit or ignition unit) is required to start and operate them. And the reliability and stability of the lamp operation will depend on the quality of the used control unit. It is necessary in order to control the voltage required to maintain a stable lamp glow. The installation of a high-quality ignition unit will allow the lamp to work for a long time, due to the fact that at the stages of ignition, stabilization and luminescence, the operating parameters of the unit will not deviate from the established limit values of the norm.

What makes biksenon different?

In addition to conventional xenon, manufacturers offer bi-xenon lamps. Their difference is that such a lamp can immediately provide both low and high beam. What type of xenon to choose depends on the design features of the car. If he envisions that both the low beam and the main beam should be provided with only one lamp in the headlamp, then this is exactly where bi-xenon is required. If the high and low beams lamps are located in different reflectors, or even in different headlamps need to take a classic xenon. For the main beam in this case, you need to buy another set of bulbs.

The principle of the bi-xenon lens is quite simple. In such lamps, the bulb shifts using an electromagnet; as a result, two different focal positions are available: low and high beam. The reflector reflects the light emitted by the lamp, forming also a powerful luminous flux directed at the lens. At the same time between the lens and the reflector is a special blind. If it is in a vertical position, it cuts off a small area of the light flux, thereby creating the focus of the dipped beam. If the curtain is in a horizontal position, then nothing interferes with the luminous flux, this allows for the focus of the main beam.

Among the main advantages of the lenses of this design can be noted: a powerful, well-directed luminous flux that can illuminate the entire width of the road. When driving at night, you get a wide overview, which significantly reduces the likelihood of an accident on the road.

The dependence of the color of xenon lamps on the glow temperature

The xenon lamps offered in stores have certain differences. In particular, the shade of their glow depends on the temperature of the glow. It can be different and yellow, and white and blue. Features of their operation also depend on it. Let's see which lamps give what color.

4300K

Xenon car bulbs with a glow temperature of 4300K give out even light with a yellowish tinge. As a rule, they are used as anti-blurred or in headlamps. It should be noted that the standard lamp, which are installed on the machine at the factory, have a temperature of exactly 4300K. This is determined by their high light output, which is about 3400L, as well as a pleasant color to the human eye. They do not blind and almost do not attract the attention of other drivers. Their glow is very clearly visible on wet pavement.

5000K

Car bulbs with a similar temperature also have a luminescence as close to white as possible. They are also commonly used for installation in headlights or fog lamps. Among the main features and advantages, it is possible to single out the fact that such lamps have a very high luminous efficiency, their power is about 3800-3900L. This is the highest possible light output for car headlights. On the road, their glow does not interfere with other road users, since the white color is very well perceived by the human eye.

6000K

Lamps with a color temperature of 6000K give out light with a slight blue tint. Their luminous intensity is about 2900-3000L. That is, the power of the glow, they are slightly inferior to their fellows with a temperature of 4300 and 5000K. They have one more, more significant disadvantage on wet roads their light is not enough to ensure a good level of illumination. Lamps with a lower temperature cope much better with road lighting in wet rainy weather.

Advantages of xenon lamps

Lamps of this type are very practical and have many advantages compared to conventional light bulbs. There are several most important advantages:

High luminous efficiency.
Cost Effective they consume less energy, which will save battery life.
High intensity light output.
Light is generated through an electric arc, it is obtained as natural as possible, very similar to daylight, which is very gently perceived by the human eye.
Long service life, such a lamp can continuously shine for more than 2 thousand hours, in addition, they are resistant to vibrations, which also has a beneficial effect on the time of their operation.
Good reflection from road markings and warning signs, this significantly increases driving safety at dusk or at night.
Excellent visibility in adverse weather conditions (rain, fog, snow). This contributes to the fact that the driver can notice the danger on the road. The peculiarity is that xenon lamps do not create the so-called “light wall” effect, that is, the driver will see not the raindrops, but the roadbed.
Low heat. In the process of operation, only 6% of energy is converted into heat in these lamps, for comparison, for halogen ones this figure is 40%.
Careful attitude to optics. Installing a xenon lamp does not affect the state of the headlights, the optics remain transparent. There is no excess heat, so the headlights are not deformed and not cloudy.
