Is the headlight type hitting the wall the following? The premise is that the car lighting system software Xiaobian has not been modified, which is the initial state of the car leaving the factory and belongs to all normal States. Let me briefly introduce the relevant national automobile lighting standards:
1. international automobile lighting specification: at present, there are two management systems in the world: en standard ECE management system and British SAE management system. The regulations of the front light field are different: ECE management system pays more attention to ensuring the driver's vision bright in the low light condition of car headlights, and at the same time, it needs to ensure the driver's vision dark directly opposite the lane change, which is more conducive to driving at night.
Safe, but SAE management system pays more attention to illuminating its own ground, and needs a very good line of sight when vibrating the ground. Therefore, most countries in the world are applying early childhood education management system.
National lighting regulations: China's automobile lighting regulations refer to ECE management system regulations, the current standard GB4599-2007: led luminous flux (tungsten filament type) characteristics of automobile headlamps, GB2 1259-2007: regulations of automobile gas-filled discharge lamp light source headlamps,
GB2599-20 10: specification for LED headlamps for automobiles. It is stipulated that the light shape of automobile headlights is asymmetric and encrypted, and there is a clear dividing line between light and dark in low beam conditions, so that the driver's own line of sight is clear and cannot cause glare to the other side.
The origin of "high beam dog": Because many drivers have different conditions when learning and training safe driving, the new national road traffic law has no established punishment measures for illegal application of low beam, in other words, cultural education is the leading factor, so there are many people who use high beam illegally in the street at night, and these people are called "high beam dogs". Everyone has undoubtedly experienced it.
In the case of lane change, the car directly opposite still turns a blind eye after receiving the data signal of your switch light, causing dizziness for a while. My real experience is very painful. And I can understand the car buyers who modified the lights in the middle and late stage. After being "blinded" by someone else's high beam, the light is clearly modified, and those who use the light illegally will come again. There are also many videos of road traffic accidents caused by too bright lane-changing lights on the Internet.
Application of low beam lighting: low beam: when the lane distance is changed to 150m, it is changed to low beam lighting, and the lighting distance of low beam lighting should be greater than 30m high beam: it is stipulated to use high beam lighting in natural environment without auxiliary lighting or driving in very dark conditions. If there is a car in front of 100m or the speed is less than 30km/h, it is not allowed to be used, mainly to avoid dazzling the car in front.
The light shape of automobile headlights has been adjusted and inspected before leaving the factory. I don't recommend refitting headlights. On the one hand, there is a risk of car burning, and at the same time it will bring inconvenience to the annual inspection of cars. Finally, advocate driving safety and refuse to be a "high beam dog"!
The actual effect of LED bulbs in low beam road construction is very good, and the disassembly and replacement are relatively simple. However, because the color temperature of LED is too high, the light wavelength is too short, and the penetration is poor. Therefore, the modified led in the middle and late stage is not suitable for high beam. Especially when the temperature is foggy, after the LED headlights are turned on, most of them are white, and there is no way to identify the ground. Some cars integrate low beam and high beam.
Generally, the low beam and the high beam of a hernia lamp are integrated. In other words, a * * * has only two lamps, but it is responsible for both the low beam and the high beam. When I modified the lamp, I noticed that this kind of hernia lamp with integrated low beam and high beam had a sun visor blocking part of the light source above.
Car headlights are a little different, which is the manufacturer's intention. The purpose depends on ensuring your safe driving and clear vision, while preventing dazzling the other driver when changing lanes. Therefore, when we realize that our vehicle lighting is a little different, we will feel sorry for it. All this is normal.
In some cars, the low beam and high beam are integrated into two lights, but at the same time they have to act as low beam and high beam. I noticed one thing when I modified the lamp. To change the light source, it is generally enough to change the LED light bulb. If the light source is specified as high, the total distance can be changed, and xenon lamps, LED lamps and laser headlights can all be changed. If some light sources must be added with lenses, the actual effect will be better.
Most of the original LED headlights are like that, ranging from 55W to 65W, and the color is mostly below 4000K K K. The low beam is actually as bright as the high beam, but the light is shone downward, and the color of the light is close to the road street lamp, which looks not bright. (The original lamp has this problem, except HID)
If you want to light it, you can change a set of lights, the color is between 4000 K and 4500 K, so the color is white. If the subject turns on the high beam on the gloomy road, remember to switch to the low beam as soon as there is a car coming from the opposite side, so as not to dazzle the other side.
