La clasificación actual debería ser la siguiente: Faros láser - faros LED para automóviles - faros xenón - lámparas halógenas. Por razones de costo, los fabricantes de automóviles suelen utilizar lámparas halógenas como estándar, las primeras lámparas de xenón como fuente alternativa de luz halógena, con la madurez y el desarrollo de la tecnología LED, muestran gradualmente el valor potencial de las lámparas halógenas alternativas y las lámparas de xenón.

As the eyes of the car, the headlights play a vital role in driving safety at night. With the development of automobile science and technology, the types of automobile headlights are also continuously improved. From halogen headlights to laser headlights, they are successively applied to different models. Different types of headlamp sources have their own advantages and disadvantages. Now let's introduce the characteristics of four common headlamp sources.

Car headlights, that is, what we often call high beam lights and low beam lights, I like to compare car headlights to eyes, because they can illuminate our way forward, and from the appearance, the left and right headlights are as bright as people's two eyes. At present, there are three kinds of automobile headlights on the market: halogen headlights, xenon headlights and LED headlights. The three kinds of headlights have their own advantages, so how should we choose as car users? Next, Xiaobian will explain it one by one.

1. Shape One of the most remarkable characteristics of LED lamps as automobile lamps is that they are actually composed of a large number of lamp particles with small volume and high brightness. They are generally combined into a certain shape, such as a lamp line or a large overall area. Xenon headlights, as automobile lamps, are generally relatively independent individuals. Of course, some models use Bi xenon headlights.

Since talk about LED, must first say now why it is so hot, we all know, at present the car mainstream headlights no more than two categories: halogen headlights and HID xenon headlights (high intensity gas discharge lamp), the rise of LED headlights compared to these two mainstream headlights what advantage?

The two hidden dangers that affect the reliability of car lights are the original lights are not bright enough, the car lights are attenuated, the lamps are aging and other reasons, so most owners will change the LED lights. So what are the advantages of LED lights? Today we will introduce it to you.

Have you ever seen water droplets/fog on the inner wall of your headlights? Small white car owner friends generally see such pictures will think that the headlights "water", want to open 4S shop processing, but the old driver know that this is a normal natural phenomenon, in order not to let the small white continue to small white, today xiaobian will explain to you why there will be water droplets/fog phenomenon.

Automobile halogen lamp in addition to call halogen lamp has a name is "high uv halogen lamp, the lamp mainly as a green the flux, the wet film and dry film exposure, bulbs, halogen lamp luminous principle like the home is to rely on tungsten filament to glow, but not limited to tungsten wire itself resistance to the high temperature, considering its melting point, Therefore, most of the original bulb is set at 60W, but the 60W bulb can only emit 1000 lumens. If it is modified into a 100W bulb, it is 1200 lumens at most. The halogen lamp needs corresponding ballast and trigger in the use process, and the biggest feature is the high uv intensity of the lamp. This is especially true for black and white dry and thick-coated products.

Since the last century, our country's economy obtained the unprecedented development, the development of science and technology has been constantly innovation, at the same time people's life also got very big change, a lot of people use their smart brain to create a very more wealth, at the same time, our country's economic development momentum very rapidly, so to speak. Since then, many people who had already made money bought themselves a car.

Halogen headlamps are made of tungsten filament. Halogen gases such as iodine or bromine are injected into the tungsten filament bulb. At high temperature, the sublimated tungsten filament chemically reacts with the halogen.

With the development of automobile science and technology, the types of automobile headlights have also been improved, and halogen headlights, xenon headlights, LED headlights, laser headlights have been applied in different models, different types of headlights have their own advantages and disadvantages. So, these kinds of headlights, which is the best headlight source?

For the car, the lamp is just like its eyes, especially in the night when driving the lamp is indispensable parts of the car. Led headlights are a common lamp in the market, and xenon headlights is a more popular headlights, we often hear its name in the car modification, what led headlights and xenon headlights which good? The following xiaobian will introduce the related knowledge of LED headlights and xenon headlights.

LED headlights are also gradually becoming the mainstream in high-end models. Car headlight development to now, has become a way to show personality and grade, and now many consumers in the purchase of cars, also began to pay more attention to the configuration of the headlight. From the most basic halogen, advanced xenon headlights to the new force LED, full of the sense of the future laser headlights, what are their advantages and disadvantages? How should different headlamp form choose after all?

energy saving, low cost: LED luminous efficiency is high, is nearly twice the fluorescent lamp. If we use our daily CFLs as an analogy, CFLs use 4/5 energy less than incandescent bulbs, while LEDs use 1/4 energy less than CFLs. In cars, the same daytime running lights use only 1/20 of the energy of halogen lights. The cost of LED components has also been greatly reduced year by year, and currently costs and prices are still falling by more than 20% per year.

There is no doubt that LED products have a broad market prospect, especially in the field of lighting. If the LED light source is widely used in the lighting field, it will be a revolution in the history of human lighting. However, restricted by technology and other factors, it can not be widely promoted at present. Now there are many LED products used in the field of lighting, such as LED fence light, LED lawn light, LED spot light, LED water bottom light, LED buried light, etc.

A halogen automobile headlamp light source Halogen lamps are the most common application in auto car headlights, one of the halogen lamps with 40 years of development history, incandescent light bulbs, halogen headlamps is improved

There are four kinds of automobile headlights, namely halogen headlight, xenon lamp, LED headlight and laser headlamp.
