The value of Best LED Headlights On The Market is difficult to overestimate. They point the way to the driver in the dark or in bad weather conditions. Therefore, their value is difficult to overestimate. However, not all lights are "equally useful": some shine better, some worse, and some are almost useless. Today we offer to evaluate the effectiveness of LED headlights.
Xenon loses both its position and relevance, the headlights are not gradually led by LEDs, although in some positions they still continue to lose. Many motorists who have not met with these lamps, a logical question arises: is it worth changing the headlight standard optics to more efficient diodes?
Talks and numerous discussions of LED-lamps are actively provoked by Chinese manufacturers, supplying to the market a huge number of different variants of lighting devices for headlights. Despite the cheapness of Chinese products, they are a good opportunity to “touch” the goods with their eyes.
Playing without rules Let's try to figure out how good the LED bulbs are. Manufacturers say (and this is confirmed by practice) that modern LED lamps can last up to forty years (naturally, these are test conditions simulated by computer). They can even withstand temperature drops from -50 to +50 (if only the LED chip itself does not heat up above 75-80 ° C). In addition, they are not afraid of vibration and shock. If we talk about light output, then it is up to 30–60 lm / W (for comparison: for a incandescent lamp, this indicator is 10–17 lm / W). And this is not the limit. Every year new devices come to the market with increasing light output. If we talk about high-quality crystals, they practically fit into these limits.
An important advantage is the fact that diodes are produced in all types of bases. Tireless Chinese manufacturers took care of this. There are a lot of Led designs - with one, two or even 10 LEDs, with a small focusing lens or without it.
All of the above is certainly evidence in favor of LEDs.
However, there are nuances. They consist in regulating the use of devices. As is known, there are UNECE Regulations No. 112, which became the basis for the development of national standards for automotive lighting (for example, GOST R 41.112–2005). These documents state that headlamp marking C indicates dipped beam, R indicates the distant one, and CR is intended for dual-mode (dipped and main) light. This classification is relevant for conventional incandescent bulbs. But HC, HR and HCR markings regulate the use of halogen lamps. The standards are also created for HID gas dischargers - UNECE Regulation No. 98 or GOST R 41.98–99. More information about them can be on the official website of the Economic Commission for Europe.
AUGMENTED REALITY TECHNOLOGY FOR PROFESSIONAL WELDERS
In early February, seminars on the use of augmented reality technology for training welders were held at technical colleges in St. Petersburg. The organizer of the seminars, during which teachers and students were able to test advanced training equipment, was the company WiederKraft - the official supplier of visualized reality systems Soldamatic.
Training workshops on modern welding technology training were conducted on the basis of the St. Petersburg Automotive College "Automechanical College" and the St.Petersburg State Technical College St. Petersburg Technical College. They were attended by teachers, masters of industrial training and students of educational institutions of technical profile. For the attention of teachers and students, WiderCraft presented the newest virtual training simulator Welder Soldamatic.
The simulator is designed for training in welding business in colleges, universities and other educational institutions, as well as directly in manufacturing plants. With its help, it is possible to study and master in practice all the main types of welding: manual arc welding, semi-automatic welding in shielding gas, and wire welding. The work of the Soldamatic training complex is based on the use of the latest augmented reality technology, which allows you to add or, more precisely, impose virtual elements on real-life objects. Thanks to this, it is possible to gain experience in connecting various products with the help of welding right in the classroom.
To work with the training complex, the student puts on a virtual helmet, picks up a special torch with a sensor that is an exact copy of the welding torch and begins to “weld” blanks of special material. Due to the technology of augmented reality, blanks (when you look at them through a helmet) look like real metal parts that are gradually connected by a weld. Welding arc, flying sparks and splashes of metal ... Full imitation of the actual working conditions of the welder!
At the same time, the Soldamatic training complex controls all the actions of an intern on which the quality of the welded product depends. Labels are displayed on the helmet's screen, which show at what angle you need to hold your hand, at what speed to drive the electrode, etc. As a result, the trainee gets the opportunity to hone the right techniques to automatism even before using real welding equipment.
In turn, the teacher at any time can open system-generated reports and videos to analyze the mistakes of each trainee. This allows the teacher to prepare personal tasks for each student to eliminate specific shortcomings. As a result, thanks to advanced technologies, learning the profession of a welder becomes more targeted, focused and effective.
Seminar participants were able to personally verify this and independently work with the simulator. Having appreciated the possibilities of Soldamatic, the teachers discussed the prospects for the use of such training complexes when training specialists of technical professions.
