Winter day short night long vehicle lighting needs attention

According to foreign statistics, 60% of car accidents are caused by unclear sight, therefore, many high-end luxury cars and European cars are automatic headlamps as an important and basic active security configuration. Now we are in some domestic high-end cars often can see some cars during the day the lights are lit, this is automatically set the vehicle factory, for security reasons, not bad or the owner forgot to turn off the lights.

Daytime in winter should become the trend of early lights lights as an important part of the vehicle configuration and the body shape of the punchline, its most basic function and safety, but often ignore some car owners. In Sweden and Canada, daytime driving lights must be switched on. According to foreign statistics, 60% of car accidents are caused by unclear sight, therefore, many high-end luxury cars and European cars are automatic headlamps as an important and basic active security configuration.

Winter day short night long, need to open the headlights in advance

In Sweden and Canada, it is necessary to turn on the headlights during the day because of the bad weather and frequent snow. This provision has begun to prevail in continental Europe, in some parts of eastern China also began to try. Some cities in Zhejiang in order to prevent the occurrence of traffic accidents, the introduction of the "driving lights during the day" provisions. During the 4 months of the pilot, the traffic accident police number fell by 13.6%. During the day to open the headlights, not to the needs of lighting, but to make other pedestrians, motor vehicles to see their cars as soon as possible, so that the other side as soon as possible to prepare to ensure safety. The brightness of the lamp is the key to improve the brightness of the knowledge is just to turn on the lights, often turn on the lights, just to avoid the risk of traffic.

In fact, the brightness of the lights is the key to the problem. The reason is, at dawn and dusk, the weakest human eye recognition ability to the color and shape of the pupil in the alternation of day and night work. This time the light has been inadequate, it is the gray feeling (and the pollution of the city more deep in this situation), the original can be at a distance of 300 meters on the clear judgment, this time generally have closer to 50 meters.

Enhance the brightness of lights, the traditional approach is mainly two. One is to enhance the power of the headlights. But the effect is limited and there are certain hidden dangers. For example, the 50W headlamps replaced by 100W, the brightness will not simply increase. On the contrary, because the power increased, the damage caused by line increases, causing the line heating wire, accelerated aging, and lead to the line load increases, planted the hidden dangers of accidents, and the lampshade and lamp bowl are dangerous deformation, discoloration caused by high temperature. Another way is to use xenon lights, brightness is indeed a lot of improvement. But its disadvantages are also obvious. Is a high price, not easy to install, forcibly converted xenon light can cause the original car light distribution does not meet the national standard, the price can be consistent with the original lamp lighting standard and unusually high. The main problem is the HID lamp color temperature is too high, resulting in the light rain and fog weather penetrating even than ordinary light, so it is not recommended.

In view of this situation, some well-known car manufacturers are in recently launched a new series of nocturnal light, which is well adapted to the needs of the midnight, affordable and convenient installation.
