Nowadays, lighting modification has become an important project for many car owners to modify their cars. Dazzling lights can not only increase the turn-back rate of your car, of course, the most important purpose of changing lights is to make you drive at night with better lighting and safer driving. Driving safety at night depends entirely on lighting. I believe everyone has a deep understanding! Good lighting effects can also make you very comfortable to drive at night and reduce fatigue! Compared with other car modifications of several thousand yuan and ten thousand yuan, such as film pasting, stereo, etc. Changing lights is the most practical modification! Movies, audio, etc. Are dispensable, good or bad! And the lighting is directly related to your driving safety at night! The lighting change we made is to transplant the whole set of dual-lens xenon lamp system equipped with the original high-end car to your car perfectly, so that you can enjoy the same lighting effect as a million-class car! However, many car owners have many misunderstandings about lighting modification. Here are some common questions about lighting renovation.
1. Can the headlights with modified lenses pass the annual inspection?
A: The lighting change we made is to transplant the whole set of dual-lens xenon lamp system equipped with high-end original car to your car in a professional way, so that you can enjoy the same lighting effect as a million-class car! Since millions of cars can pass the annual inspection, your car can also pass the annual inspection because it meets the national lighting standards. If only xenon lamps are installed without lenses, the annual inspection will fail. Need to replace the original halogen lamp or find a scalper!
2. Will the headlights be fogged?
A: Many car owners are most worried about whether there will be water and fog after the headlights are modified. The quality of headlight seal is also an important standard to test the technology of a lamp changer. Whether it is our manually modified headlights or the original headlights, the sealing process is actually carried out by hand. Therefore, in order to meet the high standard of sealing requirements, in addition to good technology, some necessary headlight sealing tools are also essential, such as professional constant temperature oven, imported plastic nail gun, air pump and so on. Using professional sealing tools can reduce the probability of water fogging to about 1% (the original headlights also have such a probability of water fogging). In addition, all headlights have air holes behind them. When the air is humid, a small amount of water vapor will enter the headlights through the air holes. This is a normal phenomenon, and it will dissipate naturally after turning on the light for a few minutes. Therefore, the car mainly treats this phenomenon rationally. If there is a large area of water droplets, it is a sealing problem.
So why do you need to upgrade your headlights?
A: car headlights is an indispensable and important system related to driving safety and an important guarantee for our driving safety at night!
Theoretically, since driving is inevitable, driving accidents at night are not as simple as crashing during the day, and may be fatal. Serial crashes often occur on high-speed, all because of poor eyesight in rainy and foggy weather, so how to maximize driving safety and headlight lighting effect is a rigorous and urgent problem, with more light and more peace!
First, why should we upgrade and modify the headlights? Why do the headlights configured when the car leaves the factory need to be upgraded?
My lamp is too good to need to be modified (this is a common misunderstanding)
Usually, a car is equipped with standard headlights when it leaves the factory. Different cars are different, because limited by production conditions and cost, they may only reach the standard, and car headlights will have a decrease in brightness after high temperature oxidation during use. Just like our bodies, we are a healthy living body when we were born, and we are healthy now, but it doesn't mean that we are healthy and will be healthy in the future. Therefore, we need to improve our mechanism through exercise, fitness and health preservation, so how to reasonably strengthen and improve the performance of headlights and let them play the most efficient role for us in driving is the real purpose of headlight upgrading and refitting!
Second, what is the main purpose of modifying headlights? What are their functions? There are several ways. What is the difference?
Now people are familiar with the modification, that is, the modification of lens angel eyes and devil eyes. Some riders mistakenly think that changing lights means installing angel eyes and devil eyes, just for the sake of beauty, so they choose their favorite colors as the focus and blindly choose without knowing the real purpose of the modification. Some merchants have grasped the customer's psychology and induced the customer to modify it, but they can't even get a truth after spending money! Generally speaking, the modification of headlights is divided into two parts. The first is to improve the lighting effect of headlights and modify dual-lens lenses, which is the purpose of most riders' modification. The second is to beautify the lighting, install angel eyes and devil eyes, and modify them purely for beauty. Advocate the majority of riders to understand the purpose before modification, distinguish between the first and the second, and gradually and reasonably modify!
At present, there are three ways to modify headlights:
1, replacing ultra-white light bulbs, replacing high-power light bulbs, and adding reinforcing wire groups are economical but not practical, and the effect is not obvious. If you buy inferior products, the risk is very great, from lamp to lamp, the fuse is blown, the circuit is burnt out, and the headlights are burnt out, resulting in line accidents.
2. It is economical and practical to install xenon headlights. However, there are dozens of xenon lamp brands on the market now, ranging from hundreds of cheap ones to more than 2,000 good ones/kloc-0. No one can say for sure about the quality, and the substandard workmanship largely determines the spotlight effect after installation. Because the focus of xenon lamps is different from halogen lamps, xenon headlights are very astigmatism and dazzling after installation, which seriously affects others' driving.
3. The installation of double lens is a little more expensive than xenon lamp, which is mainly divided into domestic parts and imported parts, with a big difference. If you really understand it, you will find it very expensive and worthwhile. First, it solves the problems of low beam glare, insufficient illumination width and insufficient brightness. The second is to give full play to the role of headlights. After modification, the original two high-beam lamps were changed into four high-beam lamps, and the brightness was improved by more than 260%, achieving the purpose of dual-purpose xenon lamp. This is the best effect of refitting headlights in one step, without wasting money!
2. Why should I add a lens to the modified headlights?
A: Let's take a look at the lens first. Lens is a kind of fish-eye lamp, which began to appear in high-end cars in recent years. The EU mandates that xenon lamps must be equipped with lenses before leaving the factory. The function of the lens is to make the emitted light more concentrated, concentrate the limited brightness on the road surface, and at the same time, the light will not spread and hurt the opposite cars and pedestrians, making driving safer. In recent years, the low beam of the original headlights of high-end cars and most mid-range cars are also equipped with lenses, but they are only low beam single beam 55W halogen lenses, and the high beam is an independent 60W halogen reflective bowl. Nowadays, high-end cars are equipped with a dual-lens xenon lamp system, which provides a dual-lens low beam and high beam source with a 35W xenon lamp to achieve the perfect effect of brighter, better light type and more energy saving!
Nowadays, many irresponsible businesses directly replace xenon lamps without installing lenses, which is wrong and strictly prohibited abroad. First of all, the reflective bowl of the original car is designed according to the focal length of the halogen bulb of the original car. Changing the xenon lamp directly will lead to the phenomenon that the focal length is not allowed to diverge, which will cause the light not to follow the road and dazzle the current car. In particular, it is not recommended to install xenon lamps in the high beam of the original car, because the start of xenon lamps is delayed, and the delay in lighting will cause danger at high speed. Therefore, it is suggested that the lens must be installed at the same time when refitting the xenon lamp.
3. Type and function of lens
A: According to the structure, lenses can be divided into single lens and double lens. Generally speaking, the lenses of high-end cars are xenon bifocal lenses. Lenses are generally composed of lenses, reflective bowls and shading sheets, and the effects of different lenses are also very different. The lens is a precise optical instrument, so the precision and workmanship of the lens and the optical data during design determine the light type and quality of the lens. The light of inferior lenses on some domestic cars is not even as good as that reflected by reflective bowls.
4. What is a dual optical lens?
A: Dual optical lenses are lenses with the function of switching between far and near light, while single optical lenses are the opposite. The dual optical lens controls the switching of far and near light through the shading sheet and motor inside the lens. This dimming method has many advantages.
First of all, the focal length between the luminous point and the reflective bowl will not change like H4 telescopic lamp, so there will be no astigmatism after dimming.
Second, when the light shield is dimmed, there is no dimming delay.
Thirdly, the shading sheet only covers the high beam when it is in low beam, and only releases the high beam when it is in high beam, so there will be no problem that the near beam will be blacked out after it turns into light like H4 lamp.
Fourth, if the original car has an independent high beam, it can have two groups of high beams after modifying the dual lens, and the intensity of the high beam is self-evident.
5. About color temperature and penetration
A: Many people mistake the color temperature K value for the brightness of light, and think that the higher the color temperature, the higher the brightness. In fact, this understanding is completely wrong. Conversely, the higher the color temperature, the lower the brightness. Normal lighting's color temperature should be 4300-6000K K, too high will lead to decreased brightness, decreased penetration and too low color temperature. Yellow light is easy to cause visual fatigue. The higher the color temperature, the lower the penetration of rain and fog. 4300K is a dividing line, which is the k value that spectrum can produce the maximum brightness. The lower it is, the yellower the light is. When it reaches 3000K, it will be called "golden eye". The higher it rises, the bluer the light, even purple. Finally, it becomes a "color light bulb" with insufficient brightness. This is the law of physical spectrum: color temperature is inversely proportional to brightness, and the higher the color temperature, the lower the brightness.
Many people think that xenon lamp has poor penetration, which is not as good as halogen lamp. Penetration has nothing to do with xenon lamp or halogen lamp. Xenon lamp or halogen lamp are just two kinds of light bulbs with different luminous principles. Penetration is only related to the color temperature (K value) of light. Xenon lamp can realize various color temperature values by adjusting xenon pills. The color temperature of tungsten filament in halogen lamps is about 3500K K K. Many halogen lamps improve the color temperature by coating blue film on the bulb wall, which is achieved at the expense of brightness, which is an undesirable practice. Generally, the recommended bulb color temperature is between 4000 and 5000 K, which is the most suitable color temperature value for automobile lighting by combining brightness and penetration. Many people think that the penetration of xenon lamps is not good, because many irresponsible businesses outside have installed some xenon lamps with high color temperature for many car owners, and the light color is blue or even purple, so the penetration is not good and the brightness is very low. So please don't mistake the difference in penetration for the characteristics of xenon lamps. Finally, let me explain what infiltration is. The ability of any light to shine on the road in rainy and foggy days is greatly reduced. This is because the water on the road reflects the light twice, which is why we usually feel that the water on the road absorbs the light in rainy days. No matter what kind of light and color temperature, the lighting ability will be reduced in rainy and foggy days. The penetration of yellow light is better than that of white light, which means that yellow light can easily penetrate the fog and let the car behind the fog see your light, instead of saying that your light can penetrate the fog and shine on things behind the fog. Fog lights are just warning lights, not for lighting, so please turn off your fog lights for those riders who are driving in the city on sunny days. The glare of fog lights is no less than that of high beam lights.
Now many car owners have the following doubts and concerns about changing lights. For these questions, here are some explanations and answers:
1. Do you want to change the lamp manually or choose some auxiliary factories to refit the headlight assembly?
A: Many car owners have some concerns about changing lights manually (these concerns will be answered one by one below). They choose some small domestic factories or the so-called Angel Eye/Tear Eye refitted headlight assembly under the banner of Taiwan Province Province. When these small factories produce these headlight assemblies, they are often shoddy because of technology, cost and other reasons, and attract consumers through some fancy appearances, but these headlights let us see their quality under the glamorous appearance.
In order to save costs, these small factories often use some inferior materials to make lampshades. The temperature inside the headlights is very high. If the lampshade material is not good for a long time, cracks will appear, and the situation shown in the above picture will appear seriously.
In addition, the light transmittance of inferior lampshades is also very low. We modified the lens inside the customer's headlight, but we found that before closing the lampshade, the brightness of the original excellent light decreased by at least 50% after closing the lampshade (no exaggeration), and the original straight and clear cutting line became blurred, even three or four tangents appeared. We compared this kind of lampshade from the vice factory with the original lampshade. When you look through the original lampshade, you find things very clear and transparent. But when you look through these inferior lampshades, you will find that many things are deformed, just like looking through a mirror. So at first glance, you feel the same about this lampshade, but when you compare it, you will find that the difference is actually very big.
In addition, the matching lenses in these inferior headlight assemblies can not pass optometry detection at all. These small factories have no optical data for manufacturing lenses, but only imitate some imported lenses by appearance. Of course, the light from such a lens is also pleasing.
The original car has a lens, but it is a halogen lamp. Can I directly match the xenon lamp?
Answer: Halogen lamps and xenon lamps have different luminous principles and different emphases, so directly replacing xenon lamps with halogen lamps often cannot achieve ideal results. It is suggested that the special xenon lens should be replaced and a special xenon lamp should be used for better effect.
4. Will the xenon lamp be dazzling after changing the lens?
A: Lens is the development trend of car headlights. The role of the lens is to standardize the lamp type and concentrate the limited brightness on the road surface, instead of shining everywhere like a reflective bowl. Therefore, when the lens headlights pass by, they are not dazzling at all. They look brighter by themselves and not by others.
5. Will the effect of changing lens xenon lamp be worse than halogen lamp in rainy and foggy days?
A: Many posts have described this issue before. Penetration has nothing to do with xenon lamp. Xenon lamps also have a low color temperature value, and the penetration is only related to the color temperature value. The lower the color temperature, the better the penetration, and vice versa. Therefore, customers are advised to choose a xenon lamp with a color temperature of about 4000K, which is the best color temperature value combining brightness and penetration.
6. Will changing the lights change the route of the original car?
A: The headlights we changed are all plug-and-play and will not destroy a line of the original car. Most models are original after modification. No lines are exposed, no holes are punched, and the stability will not be fixed on the car body. So there is no need to change the original car circuit, let alone worry about the risk of spontaneous combustion.
7. Nowadays, many new models will give an alarm by computer after refitting xenon lamps, such as: Gao6, Sagitar, Ming Rui, Tiguan, Suncool, BMW, Mercedes-Benz, Audi, Touareg, New Regal, LaCrosse, Yinglang, Compass, Coolbo, Coolway, Platinum Rui, IX35 and so on. If it is not handled properly, the light will flash, the alarm light will stay on, and the headlight control module will burn out. However, these problems can be easily solved by our professional lamp changers as long as they brush the driving computer and add a special decoder. So far, there has never been any problem with the above-mentioned models we modified. Please ask the owner to choose a professional to modify them when changing the lights.
9. Is it worthwhile to spend thousands of dollars on imported lenses and xenon lamps? What are the effects of domestic inferior lenses and domestic inferior xenon lamps?
Answer: The lens is a kind of lamp with precise optical requirements. A good lens can make the limited light source brightness play a better lighting effect. On the contrary, some inferior lenses made in China, not only can't focus and standardize the light type, but will have the opposite effect. Optical instruments need tens of millions of experiments to get the best results. The design life of imported lenses and xenon lamps is generally more than 5-8 years. Many imported cars have reached the end of their life, but the headlights on them can be sold again as disassembled parts, while domestic inferior lenses and xenon lamps often have such problems when their life is less than 1 year.
Domestic inferior lenses are generally prone to the following problems:
1. The reflection efficiency decreases.
2. After high temperature, the dimming motor is easy to fail, so that the shading plate will not darken.
3. The lighting effect is poor, and the light type cannot be really adjusted.
The lighting effect of this lens is not as good as that of a reflective bowl.
Domestic inferior xenon lamps are generally prone to the following problems:
1. Fast light attenuation and fast color attenuation. After being used for about half a year, the brightness will be attenuated by more than 50%, or the color temperature will be inaccurate.
2. Slow startup: The startup speed of imported xenon lamps is generally 1-2 seconds, while that of domestic inferior xenon lamps is generally about 6-8 seconds.
3. The focus of domestic inferior xenon lamp bulb is not accurate, which leads to the change of lamp type.
4. Philips, Osram, Xiaoxi and other imported xenon lamps all use ultraviolet-resistant quartz tubes. After several years of use, the tube wall of the bulb is still as good as new, but the xenon lamps in China generally use glass tubes, and the tubes will turn white and black after less than half a year of use.
5. The design life of imported light bulbs is generally more than 3000 hours, and normal private cars can be used for more than 5 years, while the life of domestic inferior xenon lamps is generally less than 500 hours, and the service life is generally around 1 year.
To sum up, if you choose imported lenses and imported xenon lamps, you can enjoy the lighting effect of high-end cars for a long time with one investment, but if you choose domestic inferior lenses and domestic inferior xenon lamps, you can't get good lighting effect, and you have to change them frequently after sale, so you would rather not spend such money.
Imported dual-lens lenses such as Hella, Bosch, Xiaoxi and Shiguang are generally equipped with high-end luxury car headlights. The market price of these headlights is often more than 1000, and you can enjoy the effect of tens of thousands of headlights for only a few thousand dollars. Do you think it's worth it?
10, can you install the xenon lamp first, and then install the lens if the effect is not good?
Answer: If you directly replace the xenon lamp with halogen lamp, you can't directly install the lens, because the bulb models of imported xenon double lenses are quite special, such as D1s; ; D2S； D3, D4, and so on. So if you change the xenon lamp directly and want to add a lens, your xenon lamp will be invalid and all the money you spent before will be wasted. Therefore, I suggest that you change it in one step to avoid spending more money. Profession makes you take fewer detours!
