Up to a point just a few premium cars had a full LED optics in place of head light (high and low beam), among them such as: Lexus LS600H, Cadillac Escalade, Prius, Audi A8 and R8.
Such machines can be counted on one hand, despite the fact that many manufacturers have declared LED optics for their new models, but in reality, not all were able to fulfill that promise.
Steffen Pietzonka, vice president of Marketing for Hella in Germany says that in mid-2010 LED optics not only get premium-class cars such as the A8 Audi, but also ordinary, mid-market, so that one model for the Asian market in mid -2010 and two models in late 2010-early 2011.
On the other hand, the first introduction of LED optics in the head light is at a premium large sedan, but now the technology is actively implemented in hybrid cars such as the Mitsubishi MIEV and the Toyota Prius. Actually, this trend will continue for several more years, since the introduction of this technology is associated with some serious problems. So now would be a transition, the trial period, and to talk about the mass introduction of automobiles in the budget very early.
Premium segment, in turn, dictates the terms of competitive advantage, marketing experts believe that a car of this class is to be allocated in all, and especially to provide bright, safe and beautiful head light. It can clearly be seen in the performance of the model Audi A8, which has two choices - regular or LED optics Xenon (halogen) bulb. Technology works with xenon adaptive headlights and work with directed beam provide qualitative benefits for xenon light. And as soon as manufacturers achieve efficient operation of the adaptive switching of the light beam for LED lights (which, according to the experts, could happen in the next 3-4 years), the LEDs will have a competitive advantage over xenon.
LED headlights with adaptive design number 80-100 LEDs simply will fail after a few years of use. In addition, the technological solutions used in LED headlamps, such as an active heat sink, special reflector and very cost high-power LEDs is not conducive to lower prices across the headlights.
LED Paran kotsept quads Volkswagen's L1 were shown module called Joule, consumes only 19W, brightness comparable to 55W halogen light source.
In conclusion, we note that at the moment the use of LEDs in the light head (near, far and PTF) in the factory is not possible. Even taking into account the fact that the LED lamp for premium cars is about 300-400 000, it is necessary to make, and even more so in a safe and correct way to replace the halogen light sources in a "farm" is impossible.
