Hey, you may not know what you are saying. Not long ago, the US testing organization IIHS organized the world's first headlight test. The IIHS is called the North American E-NCAP and has done a lot of new car crash tests. Basically, from the perspective of car crash tests, E-NCAP is the authority in Europe, and North America is the authority of IIHS (sneakly saying that many European cars did not do IIHS test, many American cars did not do E-NCAP test). Since this headlight test is the first in the world, all major manufacturers are unprepared and objectively enough. Let's first take a look at the rating: As the world's top three car brands, the BBA has fallen to the "MARGINAL" and "POOR" range (only the Audi A3 ranks among the best ACCEPTABLE). The best car light is the Toyota Prius! So, is the world's first light factory a Toyota? Really not Audi? Let's take the BMW 3 Series as an example. Excavate the results of this test. Some media released the Prius and BMW 3 Series halogen lamps: The radiation distance of the 3 series halogen lamps is really not very good... (gray is the high beam distance, blue is the low beam distance) It seems to be really miserable, but this is the Prius's LED headlights VS 3 series halogen headlights! Now the domestically-reformed 3 series, the 316i comes standard with LED headlights, so this picture really has no contrast. So, what is the contrast between the 3 Series LED headlights and the Prius LED headlights? Please see the picture below: (gray is the high beam distance, blue is the low beam distance) 3 series LED Prius LED It can be seen that the 3 series of LED headlights exceed the Prius LED headlights in the high beam distance and cornering illumination. The advantage of the Prius LED is in the low beam, which is farther than the 3 series LED, which is why The IIHS test classifies the Prius's LED headlights as "GOOD". In the scoring weight of the IIHS headlight test, the weight of the low beam is high. (IIHS test report original: The right of low beam is more important than high beam, because the low beam is used more, and the weight of straight lighting is higher than that of curved lighting, because the accident on the straight is more than the curve.) This new test is very good. For the first time, the importance of the lights has been put on the table. I used to ask "Which is the lighting technology?" Now, I finally have a reference and publicity. Evaluation! Of course, the evaluation of IIHS needs further deepening and improvement. It also needs to include more models, such as Audi's matrix LED headlights, and the BMW 7 Series laser headlights are not in the test. Xiaobian hopes that China's C-NCAP can quickly catch up and launch a headlight test that complies with domestic laws and actual use! smart watch for kids,smart watch women,smart watch for men,customizable smart watch Dongguan Yingxin Technology Co., Ltd. , https://www.yxsparepart.com
