Lighting devices are an indispensable attribute of each vehicle. In the modern world there are several variations of these devices, but many car owners have only a superficial view of them, without understanding which headlights are better to choose for their car. Car headlights not only illuminate the path in the usual situation, and help the driver when fog and unclear weather. Together with the development of engineering, lighting technologies rapidly developed. And if the car's lighting devices were actually not different from conventional lanterns, then, today, they are complex optical devices, for which various light sources are used to work.

Car headlights with incandescent lamps, design features, advantages and disadvantages

These headlights are considered a classic version of the lighting. Earlier, they equipped all cars produced by autocompanyes before the beginning of the nineties.

By themselves, they represent a pretty simple design. Inside such a lamp is a tungsten thread and vacuum.

Headlamps with heating lamps can not be called the most bright. In addition, when working, they spend more energy. But, if you do not pay attention to the shortcomings, they are still considered the most common, simply in an improved form.

Halogen headlights, design features, dignity and disadvantages

In halogen headlights, there are also internal steaming spirals, heating to very high temperature indicators. However, they are filled with pairs of halogen - iodine and bromine.

This feature does not allow tungsten atoms to leave the sediment on the walls, increases the life of the headlights and makes the light much brighter. The average power of this optics, at the same time, is 35-60 W, and its maximum power is capable of reaching 130 W. A variety of halogen headlights are distinguished by the presence of a unique method of installation and connection to the vehicle power grid.

Headlights Xenon, Features, Dignity and Disadvantages

At the moment, xenon technology is quite popular among car owners and gaining all large revs. It is believed that these are the most bright headlights, the flask of which is filled with inert ionized gas, giving powerful and incredibly bright lighting. In this case, the spirals replace the electrodes, an arc is formed between them, which heats the xenon.

It is worth noting that the more it shines, the less energy you need. That is why xenon optics consider economical. In addition, it greatly illuminates the dark roads with a rather powerful light beam (3200 lumen).

For optimal operation of xenon lamps, constant voltage is required in 42 or 85 V.

LED headlights, design features, dignity and disadvantages

LED headlamps are a modified version of conventional light bulbs that are used to illuminate the streets only with adaptation under cars. They are the main competitor of xenon. To date, constant testing is carried out in order to figure out which headlights are better - LEDs or xenon.

LEDs appeared relatively recently. Basically, they are mounted on expensive and prestigious cars. The work of these headlights is based on bright LEDs producing a white glow.

LEDs are characterized by high brightness and reliability, their performance is not disturbed from shocks and vibrations, and most importantly - they are economical and give powerful bright lighting. Undoubtedly, such headlights can be found quite rarely, since their cost is very high. In any case, they have enormous potential and very soon they can afford a lot of car owners.

Laser headlights, dignity and disadvantages

For the first time, this unique light solution appeared in the laboratory of the popular German company BMW. They have not yet been sent to the serial release, but have already been established for individual models. The design of these headlights is pretty simple.

Several laser parts are attached to a special frame basis. To enhance the power also mounted phosphoric lens and mirror reflectors. With the help of reflectors, the laser beam is directed into the lens, after which phosphorus begins to emit light.

According to developers, laser technology is much more efficient than xenon and LEDs. In the near future, they will be presented as the most bright headlights. This is evidenced by the power of the glow, increased thousand times in comparison with LEDs. They serve much longer, and for their work you need significantly less energy. The main advantage of the new technology is the ability to adjust the power of the light flux.

Additional lighting to help driver

In recent years, automotive headlights have suffered significant changes. Instead of conventional round appliances today, completely diverse sizes and shapes are used. Traditional heating lamps are gradually moving into the background, as car owners prefer halogen lamps of far and near light.

On transport of a representative class, as a rule, LEDs and xenon are installed. Energy consumption of optics every year is growing, however, it also grows its power. But, despite all improvements, long-distance and nearest lights, headlights are usually lacking for optimal lighting of the road with poor visibility or in problem situations. Therefore, the topic of additional lighting does not lose its relevance.

In order to avoid problems on the road, car owners install additional headlights. Large firms at the initial stage are equipped with additional sources of light. In easimate models, they are either at all install, or only at the request of the client. Given the fact that many in our country use supported foreign cars, then you have to count on those functions that have been established.

Additional headlights, classification of extra headlights

In addition to the front and rear headlights, additional light sources are also installed on modern transport. Thanks to them, it is safe to ride during the fog, at night or in terms of the overall lowering of visibility on the roads. All additional headlights can be divided into such categories:

1. Driving light - long-range lighting, which differ in a small lighting force, but have quite high power for a more detailed picture of the state of the road.
   
2. Light spotlights are powerful headlights that are used to illuminate the road at night. As a rule, they are mounted on passenger cars. There are different sizes - from small to huge. Such spotlights are usually customary to be installed on the radiator or front spoiler.
   
3. Fog lights - a device that produces white or selected yellow light working in a long-wave area. Rays shine straight and without scattering, no matter how "punch" fog. These headlights set as low as possible to the road.
   
4. Additional daylight lights - profitably replace simple optics lately. The main reason for replacement is increased efficiency, as well as automatic inclusion that eliminates the forgetfulness of the car owner.
   

PRESS TIPS ON THE QUESTION OF PAPERS

It is worth noting that the choice of lighting devices for its car should be approached carefully and carefully, since the quality of lighting is responsible for the safety of passengers and the driver. When buying new headlights, it is recommended to apply only to official representatives.
