Laser lights: the principle of work and feedback

Automobile light develops in strictly established directions, which rarely change. To date, most drivers are of particular interest in LED optics. It has a lot of advantages that do not allow to approach this segment with alternative solutions. And yet technological developments do not stand still, gradually a very different concept of light supply is gaining popularity. These are laser headlights, which introduced fundamentally new qualities in the organization of optical support for a modern car.

Principle of operation of laser optics

If traditional sources of automotive light such as incandescent bulbs and standard LEDs provide, in some sense, dynamic radiation, then the laser produces monochrome and coherent scattering. This is largely due to the advantages of technology. Despite this, the design is also based on diodes, due to which the laser lights function. The principle of operation of such optics is based on the fact that the laser acts not as a source of illumination, but as an element of energy supply. For light, there are still three light-emitting diodes with a phosphorus-containing substance. It is this group with the support of the laser and forms a beam of light with the required parameters.

During the operation of any headlight, the atoms of the active substance consume energy, giving out photons at the output. In particular, the classic incandescent lamp contains a tungsten filament that emits light as it warms up from electricity. The change in the configuration of energy consumption has led to the fact that the laser headlights of the head light can provide power, which is tens of times greater than the potential of xenon lamps.

Positive feedback on laser lights

The new technology provided several advantages to automotive optics. As already noted, even in modern xenon, this headlight will benefit from power. And the consumer confirms this. So, the practice of using suggests that the strength of the laser system is several times higher than that of traditional halogens and LEDs. More accurate calculations indicate that the laser headlamps are capable of running 600 m ahead. For comparison, the maximum potential of ordinary driving light at best reaches 400 m.

But not even in basic working qualities is the main advantage of laser light. Such a source, thanks to a special operating principle, facilitated the processes of controlling the beam of light. Few users, in particular, were able to test the latest intelligent control system for dynamic laser light. However, according to experts, this direction of optics development promises a lot of new opportunities. Suffice it to say that in the latest models of German cars, laser headlamps focus on the possibility of a point-like beam feed. Thus, the system automatically tracks dangerous areas, focusing on them the driver's attention.

Negative feedback

Obvious advantages still do not exclude the negative moments of operation of laser headlights. Disadvantages are due to the same features that LEDs have. So, users note that in some situations the light is too much blind to the oncoming drivers and in general it is unaccustomed, which can distract other motorists. In addition, in existing modifications, laser lights are very expensive and this is an important point, given that not always their dignity is vital.

Manufacturers

There are two categories of manufacturers of laser headlamps. On the one hand, such technologies are quite naturally mastered directly by car manufacturers. The most successful developments in the segment are demonstrated by Audi and BMW. True, laser optics are rarely featured in mass models - such equipment is often acquired as an optional solution. And on the other hand, laser headlamps are produced by advanced developers of LED technology. We can note the companies Philips, Osram and Hella, which occupy a leading position in the field of designing the newest lighting systems. What is particularly interesting is that in both categories of the company, niche niches occupy highly specialized niches, promoting unique technological solutions.

How to make laser lights with your own hands?

On the full production of a laser headlamp with the above mentioned speech characteristics can not be, however, partial introduction of diodes of this type into automotive optics can give some positive result. So, many home masters offer the technique of manufacturing a laser pointer for a headlight, the basis of which will be a diode from the drive DVD-RW. The laser is integrated into a niche of a stoplight or an antifog headlight with correction of a beam by means of cold welding. To limit the length of the stream, you can apply a stencil, which will repeat the shape of the desired beam. Therefore, before starting to manufacture, you should determine the characteristics that laser lights should possess. With your hands, the corrective basis can be made of cardboard, leaving a window of suitable size. Usually, the headlights are made from the calculation of the beam supply at 1.5 m, provided that a 4-meter projection is provided.

Conclusion

In various areas of technological improvement of cars there are processes of active introduction of intellectual systems. Optical configuration, even in modern generations, is designed with a greater emphasis on ensuring the basic characteristics of light supply. Optimal properties of radiation have already been achieved with the example of standard LEDs. In turn, the laser headlights of the head light, along with increasing the performance of optics also allowed the developers to master and new principles of light control. Not yet in mass production, but with examples of concept cars, leading companies demonstrate impressive examples of laser headlight automation. According to experts, work in this direction should not only improve the interaction of the driver with the headlights, but also generally improve the ergonomics of the machine and the level of safety.
