Car light modification knowledge Daquan
Car light modification includes headlight modification (installation of bifocal lenses, installation of angel eyes, installation of lamp eyebrows,) instrument lamp color change, installation of chassis lights, installation of flash lights, installation of searchlights, and modification of LED interior reading lights LED taillights interior background lights and more!
Ordinary headlights directly installed with xenon lamps have serious astigmatism and poor penetration. Even the driver of the other party in the low beam cannot open his eyes due to your astigmatism, but you do not feel particularly bright when you are sitting in the car. Especially in the rainy and foggy days, the super white one looks like a white fog in front of it, which is easy to cause hallucinations! This is because the ordinary lamp cup is only designed for halogen bulbs and does not match the xenon bulb. After the xenon lamp is directly installed, it will cause serious astigmatism. Like the H4 lamp is like this. For such models, it is necessary to upgrade and upgrade. The ultimate solution is to transplant the bifocal lens in Mercedes-Benz and BMW into our headlights without changing any circuit of the original car, so as to fundamentally solve the problem of focusing and brightness. question,. The earliest xenon lamps were designed to be used in the lens so as to achieve the purpose of concentrating light far away, just because the cost of the bifocal lens is extremely high. Some economical cars are not equipped with this device in order to save costs, and only use ordinary reflector bowl structure headlights ! At present, only BMW 5 series, 7 series, X3, X5, Audi A6, A6L, Mercedes-Benz full range of Lesus and other models have original bifocal lenses.
What is a bifocal lens, and what are the benefits?
The bifocal lens is a convex lens-like thing in the headlight. In front of the condenser, there is a solenoid valve device in the middle. The bulb uses a baffle in the back reflector to realize the change of far and near light. Mechanical dimming. The dimming speed is quite fast. (, it only takes 0.1 seconds to change from low beam to high beam) will not affect the life of the lamp due to frequent starting of the bulb. Its biggest feature is that it has a wide irradiation range and a very good lighting effect. There is to make the whole headlight more three-dimensional, and it can also be installed with everyone's favorite angel eyes and devil eyes.
What are angel eyes and devil eyes?
Angel eyes are actually a colored aperture, which was first used in BMW headlights and has no actual function. It mainly plays the role of decorative beauty and width, and the colors are red, blue, green, yellow, and purple.
Is the headlight modification and installation complicated? Will it affect the line or leak?
It depends on the modification technology. The technology came from Hong Kong a few years ago. Generally, the modification shop is not qualified. Even if the lampshade can be opened, it is difficult to achieve perfect sealing. There is also vibration off the lamp, and the focus angle is shifted. And other issues. Therefore, the modification of the bifocal lens has high technical requirements, and requires the modification engineer to have high technology and years of practical experience, and also need to use some special equipment and special tools to install well. After years of practice and research and development, we are in Improvements in design, production process and tools, coupled with the intervention of special tools and materials, standardize and simplify production and installation, such as water entry, vibration degumming, and optical focus angle shift, which are extremely important in our works. Rarely exists. This modification is now very common in coastal areas.
How many types of bifocal lenses are there and where do the products come from?
At present, the good bifocal lenses on the market are not made in China, even if there are domestic ones, they are imitations. There are only a few companies in the world that produce, such as Dr. Hella in Germany, Koiichi Ichiko in Japan, Valeo in France, beauty slaves, etc. Generally, the old BMW Audi uses Hella, the new Audi Mercedes-Benz VOLVOS40 uses Dr. Land Rover, Lexus, Infiniti uses Koito Q7, uses Valeo, Infiniti FX35 uses city light, and so on.
After modification, is it better to use 4300K bulbs, or 6000K ones, and 8000K brighter? Is the whiter the better?
The brightness of the xenon lamp is 3 times that of the halogen lamp, about 3200 lumens (lumen is the bright unit of light, that is, the practical illumination brightness. And K is the unit of color temperature, which is the color distinction of light. The higher the K number, the more white and blue, the less Penetration) 4300K is whitish and yellowish, the actual lighting effect is good, and the penetration is strong, regardless of rainy and foggy days. , Above 6000K, the effect of lighting the road will be lost, the color will be bluish, and the lighting will not be as bright as a flashlight! So many car owners are misled into thinking that the higher the color temperature, the brighter the lights, the more expensive the lights. This is the wrong view. We generally recommend 4300K bulbs (all high-end cars, such as Mercedes-Benz, BMW, Audi, Land Rover, Cadillac... are basically 4300K color temperature
