[Car Modification Lesson] What you have to learn about the eyes of vehicles-related modifications to car headlights

August 24, 2024

It’s time for a small class for car refitting again. Due to all kinds of things last week, there was no update. I originally wanted to talk about engine oil today, but after thinking about it, there was not enough material, so I chose to update the headlamps. This time let’s talk about car headlights in a different way!

Let’s start with a 54W R8 town building! (the picture is from the Internet)

Hello, Daga! I am a car, the headlights are my eyes, the eyes are to illuminate my master’s way forward, and at the same time, the only sign of me can be seen by the guys opposite and in front of me at night. So my eyes are also fastidious! Generally speaking, according to the changes in the market, my eyes are as follows:

The above picture shows the classification of my eyes: halogen, xenon, LED, laser. (the picture is from the Internet)

A long time ago, because my grandparents were restricted by the development of science and technology at that time, they got some inspiration from Edison, shrank the household light bulb, changed the material of the luminous body, and got the headlamps for our car. according to the standards and interface models of major manufacturers, they are divided into 9005, 9006, H1, H3, H7, H11 and other models. Its halogen is the entry of our tungsten filament lamp, but it is only small in size. at that time, there were few mirrors in it. Scientists designed my shooting music according to my spectroscopy. in most cars, there will be a reflective surface like a son around the bulb, which is calculated to increase the exposure product of the bulb, but because of the halogen lamp, it is made from the tungsten filament attenuation and characteristics of halogen lamps. The temperature of the halogen bulb is very high, so the tungsten wire of the part will break at high temperature, and sometimes it will suddenly become “one eye”. And the brightness of the tungsten wire is not high, the shooting perimeter is very limited, but this halogen bubble has an excellent, cheap, and yellow, good penetration in rainy and foggy days, so it is also very cheap for me to use, but with the development of science and technology, there is not much suitable to make halogen!

From the 1990s, some people found that the use of an electrical high voltage to stimulate the inert gas-Xenon (xian) gas will produce a very strong brightness, so they began to have HID headlamps. Because the HID bulb needs electric high voltage to stimulate, there is a kind of transformer, which is used in it. Many professionals call it a fixator.

However, after installing the light bulb, the light source is bright and the light is not concentrated on the reflective bowl originally designed for me, and sometimes our owners are unable to see the vehicles on the opposite side because of the brightness. Often lead to collisions between our companions and even hurt pedestrians. So later, through the principle of magnification, they added a bead to my headlamp, which we called “transparent”.

Lenses used in cars are also installed in halogen lamps in order to make the optical fiber more concentrated and thus increase the irradiation distance. (the picture is from the Internet)

With the addition of the lens, the irradiation distance of the HID bulb is farther, the light of the HID bulb is concentrated, and the baffle is used internally to avoid the excess flash light, which is used in the far light, so most vehicles using HID xenon headlamps have the function of far and near, from the visual point of view, my eyes are more gas. It’s even more magical!

To put it beside the point, because of the characteristics of HID headlights, it takes time to stimulate and stabilize, so this has become a characteristic of HID. It will not be stable immediately after it is turned on, and it will take a few seconds to reach the maximum brightness. If there is no lens installed or the lens aging does not meet the conditions for use, it may lead to the annual inspection of the vehicle. And because the filling lazy body also has a service life, to HID also need to be maintained and replaced, in the same case, the HID must live together with the package, the grid is now cheap, from 1300 yuan to 3800 yuan not, products from domestic snow Wright, Iwasaki, mi to Philips, Osram can be oh! But the main sex ratio, the main push small series, because it is Hella’s factory, sex ratio super! At the same time, in order to take into account the penetration of rainy and foggy weather, generally you can choose about 4800K color temperature light bulb to use. The color temperature is as follows:

Color temperature, low color temperature red, high color temperature blue, the lower the color temperature in the rain and fog weather the better, 8000K is basically pure white, so it is recommended to take into account the road lighting, choose 4800K is the best to use, the me LD POLO is the use of Iwasaki 4800K light bulb set + UPS Appa Hella (imitation Hella) 3 transparent, rain and fog weather that is more authentic than the me Kodiak’s!

In order to keep up with fashion, the me of this article has also upgraded several (more than two) sets of xenon headlamp kits, and without boasting, he is also the first person in Guiyang to use LED lenses. Later, because of the poor effect on rainy days, I tossed back to xenon.

At that time, the wing god first changed the headlights.

No more questions about color temperature will be prosecuted later! So is LED!

In fact, LED is basically the product of the same era as HID, but why has it not been widely used? Cost, of course! At that time, the manufacturing cost of LED was much higher than that of HID, so HID was very popular, and at the same time, it also occupied the mainstream automobile aftermarket and the period of automobile manufacturing. With the industrial exhibition, the manufacturing cost of LED was not reduced, even very low HID, so HID was gradually replaced by LED. Even later launched the LED bulb to replace the HID bulb, but because of the LED and HID, halogen spectrum is very different, the actual use of LED bulb without replacement and increase the heat dissipation system is a good effect.

But LED has the characteristics of low power consumption and high brightness, and once became a trend rider in the automotive aftermarket, but similarly, LED bulbs and HID bulbs have a common disadvantage, that is, the light is not concentrated, so it is not finished by installing the bulb, but also to adjust the bulb to achieve the best brightness, otherwise the LED is not installed like halogen! But at the same time, LED generates more heat than halogen, so it must have auxiliary heat dissipation equipment, usually either a small fan or a long bar (heat sink).

The cost of a pair of LED light bulbs on the market is as low as a few hundred yuan. (Picture comes from the Internet)

As a dishonest light factory, Audi, ah ~~ Bah, I’m wrong. It should be a dishonest car factory that takes LED headlights to the extreme. You will know when we look at the headlight structure of the old Audi A8.

With the development of industry, the cost of LEDs has gradually decreased, which declares the arrival of the LED era. Many compatriots bring their own LED lights when they leave the factory, but do you think the automotive aftermarket has given up just like this? Hehe, you underestimate scientists too much! With everyone’s hard work in “specialized research”, LED integrated lenses were gradually born.

The picture above shows a brand of LED integrated lens. (Picture comes from the Internet)

As you can see, the LED integrated lens has an additional heat dissipation module to ensure the ambient temperature at which the LED operates.

Next, more advanced ones appeared. Mercedes-Benz appeared laser geometric headlights, and even the HiPIX used laser headlights, which proved that laser headlights have slowly entered our lives.

Because the laser is broken down into multiple paths, the principle is actually diametrically opposed to that of LEDs and HID. The lens is used to focus light, while the laser needs to be scattered, so the laser headlights can be shaped! In other words, laser headlights can be used as an “atmosphere group” for discoop or marriage proposal, and the laser headlights can be edited in shape, so the laser can adjust its source according to the situation. Currently, there are laser headlights in the market. It’s sold, but it’s just something my master can’t afford to install! It’s so expensive!

Okay, having said this, let’s use a picture to popularize how to adjust the headlights to make it work better!

This picture is a standard image of headlight height adjustment. I think this should make everyone clear about the light adjustment?

Okay, although the material comes from the Internet, it is not easy to edit. Please leave a like or comment before leaving. It is cool (the above text content is all original. If there is any similarity, it is purely a coincidence, and some pictures come from the Internet)
