In today's automobile products, turbocharged engines are getting stronger and stronger, and the gear of the gearbox is getting higher and higher. In addition, active driving and on-board interconnection make the distance between people and the car almost zero, and new technologies are changing with each passing day. After the major brands have improved their product competitiveness and influence through new technologies, they have been changed by new technologies, and the degree of adhesion between them has become higher and higher. Thanks to the development of technology, many technologies that only appeared on the models in the past have slowly entered the lives of ordinary consumers. New eye headlights LED headlights currently, halogen headlights and HID Xenon headlights are the mainstream technologies for car headlights, but the emergence of LED headlights is like matching headlights with lenses, the charm index of the eyes is directly raised by a segment. In automobiles, the energy consumption of LED components is only 1/20 of that of halogen lamps for the same daytime running lights. The cost of LED components has also been greatly reduced year by year, and the current cost and price are still decreasing by more than 20% per year. At present, the LED components used in automobiles can basically reach the level of 50000 hours, while well-known automobile lighting suppliers can provide LED components with a service life of 100000 hours. In contrast, the life of the xenon lamp is only about 3000 hours. Compared with LED headlights, laser headlights have advantages in volume. The length of a single laser diode element can already reach 10 microns, which is only 1/100 of the size of a conventional LED element. Another significant advantage of laser headlights is in terms of luminous efficiency. When the same lighting conditions are met, the energy consumption of using laser headlights is less than 60% of that of LED headlights. However, in this future field, BMW is not idle, and the laser headlight group has been installed on the production version of the i8.
