Iodine headlamps that promised to change the world. Ferrari iodine headlights invented in 1962 were some lights fitted with incandescent tungsten filament mounted in a quartz tube that was placed in an inert gas and iodine vapor. During operation, the filament temperature reaches 3000 degrees Celsius and the bulb, ie quartz tube at 700 degrees. Subsequently, these bulbs have halogen bulbs named. The advantage of these lamps promised iodine was one: in the case of a classic incandescent bulb, while burning filament metal vapor is deposited on the inner surface and lighting efficiency decrease over time. In the case of iodine lamp, a tungsten iodine produced after ignition, is in gaseous, vapor does not allow the metal to be deposited, but were returned to the reaction gases. Name iodine lamp is also called tungsten-halogen, quartz-halogen or quartz-iodine. But from 1962 until today, almost everyone knows these bulbs with iodine as the halogen. And there are all the chances in the world and you to ride with a car that has a lot of iodine bulbs that works now, as in 1962 the hidden headlights and retractable With frenzy manufacturers to make cars as beautiful and elegant, and developed an obsession with hiding headlights. Both the United States and Europe, more and more cars began to hide the lights in one form or another. Or in the lids to the body to give the impression of aerodynamic design, often in various grille trim. Cord 110 Convertible Coupe in 1936 was among the first cars equipped with hidden headlights. Subsequently, many manufacturers have realized that to get a clean and elegant design, must give up the classic round headlights, like projectors, and integrate them into the body. Age powerful American cars, muscle-type cars, and she brought a craze among the hidden headlights. These were in place, but covered by various ornaments Electric moved through air ducts. Beyond the ocean, however, things were different. Sports cars were electric headlights, which amounted only when needed. Lamborghini Countach classic models such as the Ferrari F40 or had lights that rises from front to back, and models like the Porsche 928 or Lamborghini Miura had lights going up the back to the front.
From xenon to LED and laser technology
BMW kicked off in the xenon lamp in 1991 and wanted, 23 years later to re-enter history with laser lights. If at the time BMW was a pioneer in the field and launched the first cars equipped with Xenon headlights with auto-leveling, now, in 2014, the Bavarian manufacturer Audi took the girl with the R8. Initially, the electric i8 he wanted to be the first passenger car with laser lights, but those have damaged Audi offers the R8 LMX plans and headlamps equipped with laser beam. Perhaps the i8 will be a model with laser lights for both phases. But to the "laser, brother!" Xenon has a rather long future ahead. HID headlamps works much differently than the halogen. Light is produced by an electric arc formed between tungsten electrodes inside a quartz bulb or alumina. The lamp is shaped tube and is filled with gaseous salts and minerals that help the initial ignition, then spring is heated and evaporated mineral salts forming plasma which increases light intensity.
When xenon was promoted by manufacturers premium LED technology base. The first car with LED lights was Lexus LS600h in 2007 Audi R8 was the first car equipped with LED headlamps complete all phases, and now BMW, Audi or Mercedes-Benz come with optional LED headlights. These LEDs are actually "light-emitting diodes" and have the advantage of low energy consumption. The problem with the LED backlight is different: high heat behind making light diode. And as a beacon to be effective, should be used more LEDs that are more heat and this heat must be controlled fans. Therefore, LED systems are some pretty complex, if not well thought out and cooled, have short life.
Laser lights are the newest invention. And you should know that when you look at them, do not look at laser itself. Behind the lighthouse, three blue laser beams hitting a mirror that focuses the energy into a lens filled with yellow phosphorus. This is when it hit the blue laser emits white light intensity. This light is reflected at the front, thus making the light in the form of rays.
