Speed of over 88 km LED is also difficult to solve the hidden headlights night road lighting

The car is known as the automobile headlight network quality "eyes", but in reality, many riders tend to light the appearance of great concern, the real irradiation distance and brightness but ignore the "eye" is not able to give adequate security. Perhaps everyone in this way: the lamp technology has been very mature, but also continue to introduce new high-tech, so do not worry, but the reality is really the case?

Southern California Center for automotive research vehicle Club (AAA) recently released a survey and test report by the U.S. media and automotive circles widely discussed, the test report shows that in the absence of street lights in the rural road, the headlights do not conform to the safety standards of driving range. Even if you have the latest LED car lights, at speeds of more than 55 miles / hour (about 88 km / h) may also be unsafe. The report also compares the actual safety of the existing halogen lamp, xenon lamp and LED lights on the market, the results are not satisfactory.

Night road under black lights: headlights generally not up to safety standards

It is understood that, in order to assess the current market vehicle headlamps lighting effects and limitations, and to understand the effect of the application of the new headlight technology, AAA contrast to the ordinary halogen lamps, HID lights and LED lights the actual distance. The test results showed that both the high beam alignment, or testing, vehicle lighting and safety guidelines of the American state highway and Transportation Association of the current existing in the vehicle driving at night without lights on the road, irradiation distance of various types of lamps are not to let the owners found a safe distance from the target and timely response and brake stop.

Southern California Center for automotive research vehicle club official said, "the AAA test results showed the vehicle headlamps and did not meet safety standards, due to the medium speed is not good enough to illuminate the road, so the owners often see Qingyuan at night pedestrians or animal, really see again the brakes too late. "

Halogen lamp: over 60 kilometers per hour may not be safe?

Specifically, the night the test results of AAA showed that the halogen lamp mode at the speed to 40 miles per hour (about 60 km / h) after may not be safe to illuminate the road without lights, to the owners of the night driving safety hazards caused by, and now the vast majority of cars on the road are equipped with halogen light.

Although in the test, the halogen lamp light pattern can enhance the visual distance of 28% owners, but in the real traffic environment, at the speed of 48 miles per hour (about 77 km / h), the beam can not provide safe enough to let the owners of irradiation distance safety stop. But the AAA survey also found that only 1/3 of the owners said in the night driving process, especially in the absence of street road, will turn the regular use of far and near light.

Xenon lamp and LED lamp: night road speed can not exceed 72 km?

The test found that compared with halogen lamps, currently on the market more advanced technology such as HID and LED headlights, headlights at night without lights of the road, the radiation range is far 25%, but still reached 45 miles per hour in an hour (about 72 km / h) after can't illuminate the road safety. Open yuanguangdeng mode, the lamp irradiation distance than the mode of up to 500 feet. But despite a substantial increase, but also the most advanced headlight technology, but compared with the whole day according to the driving distance, still small 60%.

How to build a safer night driving?

Although the latest technology of visible distance visible light, so that people feel the security of security, but there is still room for improvement. A person in charge of AAA said. "With the European market to encourage the application of more advanced headlight technology is different, the U.S. government regulations are still limited to the sale of vehicle headlamps light output intensity. AAA is currently working with the U.S. policy makers to ensure that federal regulations keep up with new technologies. "

From the domestic market, government regulations on vehicle headlamp irradiation intensity and angle has very strict specifications, car manufacturers in lights technical ability to doubt, but how to let the owners can not only realize the night visual distance is long enough, the line of sight is wide enough, also not because the light intensity is too large and the impact of other vehicles safe driving, this seems to be a problem.

Fortunately, we have seen in recent years a number of new technology manufacturers, such as automatic anti dazzle mirror technology Audi manufacturers after the launch of the rearview mirror through the rear light intensity sensor for real-time monitoring, and automatically adjust the specular reflection, the glare of the lights dimmed and soft in the rear of the vehicle at night. Volvo also launched FAHB intelligent active beam technology, the technology uses a detection device and vehicle monitoring at any time to scan ahead, when monitoring in front of the vehicle, will be the projection module in the system startup, the baffle plate of the headlight automatic blocking area corresponding to the lights, do not interfere with the vehicle and vehicle front sight; the mobile, timely scan this car and the car in front of the distance, until the end of the meeting or overtaking.

Of course, in addition to the efforts of car prices and improve the relevant standards, the owners themselves in the car should also pay attention to the process of car maintenance. AAA test found that the headlight lens
