Recently, many netizens have asked the professor this question: I want to change the car headlights, but I don’t know which one to choose between LED and xenon! I believe many netizens are wondering about this question, are LED headlights awesome? What's the difference compared with xenon headlights?
Let’s first talk about the evolution of car headlights: halogen lights → xenon headlights → LED headlights → laser headlights; in crude terms, if we compare halogen lights to a loser, then xenon headlights are equivalent to a A wealthy person can be considered a wealthy person with xenon headlights, but a wealthy person with more advanced laser headlights can be regarded as a wealthy person standing at the top of society.
This is one of the most widely used headlights at present. It usually appears on the low-end models with the largest sales. There is only one reason for its wide use! That is low cost and easy to replace, making it the first choice for home use.
Xenon lamps are heavy metal lamps that are filled with inert gases. The light intensity of xenon bulbs is basically more than three times that of halogen bulbs, and the light color is not much different from that of sunlight. Starting xenon headlights requires a strong voltage, and we often have to add an electronic ballast during installation.
In this era where LEDs are rampant, xenon headlights have gradually been abandoned by society. Currently, many manufacturers will use LED headlights as their sales highlights, such as the Audi lamp factory, which has already mastered LED. However, LED headlights are basically popular in high-end luxury cars.
Once new BMWThe 7 Series has laser headlights that have moved many consumers. Laser headlights have high technical requirements and are not cheap. Although they have very good lighting effects, they are limited by the country's lighting brightness parameters. There are restrictions, which greatly inhibits the performance of laser headlights. Although they are awesome, they are difficult to develop.
Xenon? LED? Which is better!
From the perspective of modification, more than 50% of car owners will modify the lighting of their cars, and the market competition in this aspect is becoming increasingly fierce; as the professor above said, xenon lamps are heavy metal lamps that transmit light The overcharger instantly increases the vehicle's 12-volt power supply to 23,000 volts. At the high voltage, the xenon gas is ionized and creates a light source between the two poles of the power supply. The obvious advantage of xenon lamps is that they are "very bright", which is one of the sources of light pollution on the road! It is worth mentioning that "xenon" headlights cannot be modified casually. First of all, although xenon headlights are very bright, they are very hot when lit, so casual installation can easily accelerate the aging of the headlight cover and even melt the lamp holder;
In addition, xenon lamps have a slow lighting speed, high power consumption and serious light scattering, so they must be used with lenses. Unfortunately, in order to save money and lack of traffic awareness, most car owners only choose to replace a xenon bulb. This is not only ineffective but also causes light pollution, affects the normal performance of other drivers on the road, and increases the chance of traffic accidents, Professor This kind of behavior is strongly condemned here. In fact, driving with high beams on a well-lit road is almost the same as murdering someone.
The other player is the LED headlights that have already emerged. LED headlights are cold light sources. When lit, the temperature is very low, the performance is stable and the lighting speed is fast. In the early days, they were used more in brake lights and daytime driving. On the lamp. LED headlights are a very popular product in Jack Ma's family. The professor thinks this is a good thing, but here we should talk about LED headlights. The professor believes that in the minds of 90% of people, no matter which brand, LED headlights are just such a thing. But what you don’t know is that LED headlights have developed into the third generation.
The first generation of LED is lamp bead type, which is also the first choice for modification enthusiasts to modify LED lights. It has a simple structure and is easy to install.
The second generation of LED headlights uses COB cold light source LED headlights. The matrix LED headlights on the Audi A8 are a good example. An integrated headlight set composed of N LED lights. The shape is very attractive, and it can recognize pedestrians, make a series of actions to avoid lights and remind pedestrians of oncoming cars, and has a certain degree of intelligence. For example, if the first-generation LED lamp is compared to a light bulb, then the second-generation and above LED headlights are equivalent to the shadowless lights on the hospital operating table, and the gap is relatively large.
The third generation of LED headlights can be regarded as the most advanced LED headlight technology at present. The new generation of E-class is equipped with the latest third generation of LED headlights. It uses an integrated headlight module on the headlights, which can It performs functions such as low beam, high beam, turn signal and daytime running lights. It is also equipped with an intelligent lighting system and an enhanced version of the adaptive high beam assist system, which can always turn on the high beam when driving at night. You can also avoid vehicles in the high-beam beam while driving, and you no longer need to become a high-beam dog.
Having said this, some people may ask, is there a big difference between the second generation and the third generation? Although there is a difference, it is not big. In addition, these high-end LED headlights are astonishingly high in terms of technological content and cost! And for ordinary models, you can only choose to change the first-generation LED headlights; as for the second and third generations, you can’t change them even if you want to. The professor believes that most of the people who are obsessed with LED headlights are because they are "beautiful" and "stunning." Yes, technology is advancing. We often say that the eyes are the windows to the soul, and the same is true for cars. The finishing touch, a pair of stunning headlights will definitely fascinate you.
Back to the starting point, which one is better, xenon or LED? The professor believes that LED headlights are superior whether it is a later installation or from the original factory perspective. However, it is worth noting that once the headlights are damaged, the cost of replacing LED headlights will be higher than xenon lamps. However, as an outdated product, xenon lamps should be used sparingly unless they are modified correctly.
