After the emergence of automotive lighting from the Xenon lighting technology, the human headlight lighting process has finally begun to break through and develop. Twice the brightness of ordinary halogen headlamps, energy consumption is only two-thirds, such as daylight-like lighting effects, life expectancy up to ten times that of ordinary halogen lamps - since the early 1990s, helium With its incomparable advantages, headlamps have become the first choice for more and more owners. Xenon headlights greatly increase the safety and comfort of driving, and help to ease the tension and fatigue of people driving at night. Drivers can detect dangers in the first time, so that they can get enough reaction time and greatly reduce the incidence of night accidents.
Hella has always been a leader in automotive lighting and a pioneer in automotive lighting.
Newcomer. Since 1992, Hella has been committed to producing xenon headlamps for the European and American markets and has become the dominant market in the European market. After more than ten years of development, the application of Xenon lighting technology in the automotive field is steadily maturing. From the close-up of the low beam headlights, the high beam headlights and the double xenon headlamps, the fourth generation of Xenon ballasts that stimulated the Xenon source has been successfully developed. The performance of Xenon lighting is more and more stable. The prospect of replacing the ordinary halogen lamps in an all-round way is also becoming increasingly clear. At present, Hella has a market share of more than 60% in the field of xenon lighting, and supplies advanced xenon headlamp systems to world-renowned automakers such as Audi, BMW, DaimlerChrysler, Honda, Opel, Porsche and Volkswagen.
In the process of continuous improvement of helium products, Hella's technicians also made some achievements in the design of headlight reflectors. These include the FF free-reflecting surface technology and DE lens technology that have been put into use.
The emergence of FF free-surface mirror technology is closely related to the rapid advancement of electronic computer technology in recent years. Introducing the CAD design concept of the mirror development process, so that each reflection point can be tailored to the ideal light pattern. Thousands or even tens of thousands of computer-calculated reflection points form the free-surface mirror of the headlamp, which reflects the light emitted by the xenon source to the specified illumination area to the maximum extent, greatly improving the illumination efficiency. Headlamps using FF technology no longer require a lens-assisted light distribution. Therefore, the lens of such products can use a completely stripe-free lens to achieve a crystal clear aesthetic.
The DE lens technology draws on the easy-to-understand convex lens concentrating principle. In front of the traditional mirror and bulb, a specially designed convex lens is added. The dual effect of specular reflection and lens refraction achieves an ideal concentrating effect. Therefore, this technology is mostly used for low beam headlamps.
In addition, the super DE technology that combines DE and FF technologies is now used in some of the most advanced automotive Xenon headlamps.
Due to the continuous understanding of the xenon technology by existing car owners and the improvement of the requirements for car lighting, the conversion of the original car halogen headlamps into xenon lamps has also become a hot spot in the market.
At present, there are mainly three different modification methods on the market.
