Many old drivers and friends still insist that halogen lamps are the best headlights.
This is actually a bit like many friends think that Fruit 4 is the best mobile phone. On the one hand, there is design, on the one hand, there is feelings, on the other hand, the experience is really good.
Why do old drivers think halogen lamps are the best headlights?
Many old drivers used this at first.
First of all, halogen lamps appeared earlier.
Sun Ruihong, Li Zongxian and others mentioned it in the paper "Research on the Application of High-power LED in Headlight Lighting" published in the 13th Symposium on Lighting Technology and Marketing across the Taiwan Strait.
Halogen lamps replaced incandescent lamps in the 1970s and began to be used in car headlights. HID lamp, that is, xenon lamp, was developed in the 1990s.
It will be 2007 for LED lamps to be used as car headlights.
And even though halogen lamps accounted for the most in the past few years, most of my friends may still be exposed to halogen lamps.
Zhiyan Consulting released a "20 18 Automobile Lamp Industry Demand and Market Size Analysis" with data on it.
In 20 16, the penetration rate of halogen lamps was still 60%, more than half, of course, the proportion was higher before.
At this time, as long as the halogen lamp is not particularly difficult to use, it is a deep affection for the old driver and old friend.
It's like: Although Nokia was eliminated several years ago, many people still miss Nokia and have special feelings for it. Even if they have a smart phone, they will buy a Nokia smart phone to play with.
Halogen lamps do have certain advantages.
And halogen lamps are really a bit like Nokia in those days, which is really good.
Even compared with later xenon lamps and LED lamps, there are still some advantages compared with the three aspects I will talk about later.
1 Price, of course.
Refer to the data on the industrial information network: the same headlight, halogen lamp only needs about 200 to 250 yuan; Xenon lamps 400 to 500; LED is naturally more expensive, 1000 to 1500.
The light bulb needs to be changed sometimes, and I may not care when I buy it. I basically have to bear the cost of later replacement. Maybe I can just replace them for 300 yuan, so halogen lamps won't make people feel bad, right?
In addition, the penetration of halogen lamps is much better than that of LED lamps. Many old drivers and friends think halogen lamps are good and safe.
As mentioned in our previous video, when light is scattered in rain and fog, according to Rayleigh scattering law and Michaelis scattering principle: the higher the color temperature, the worse the penetration effect.
Generally, the color temperature of halogen lamp is about 3000K (Kelvin), and that of LED lamp is about 5500K, and that of some cars is 4300 K. The color temperature of LED may be higher, and its penetration is not as good as that of halogen lamp.
This means that halogen lamps have certain advantages when driving in rainy and foggy days. You might as well go and see if the fog lights of most friends' cars are yellow or white. Right?
Finally, the halogen lamp doesn't look tired. How do you say this?
Yan Yonghong, Yan Ning and others published a paper "The Influence of Light Source Color Temperature on Brain Wave Rhythm and Learning Efficiency" in the Journal of Civil Architecture and Environmental Engineering, which was mentioned above.
There are significant differences in the change rate of brainwave index under different color temperature and light intensity.
The excitability and sensitivity of the brain will increase with the color temperature and illumination value of the light source, but fatigue is more likely to occur in high color temperature and illumination state.
The color temperature and illumination of halogen lamps are relatively low, so turning on the lights at night seems to make your eyes less hard.
Some old drivers have only used halogen lamps.
In addition, a small number of drivers and friends have only used halogen lamps, not xenon lamps or LED lamps. At this time, they are more sure that the halogen lamp in their car is invincible and the best to use.
Just like playing a game. You are just playing a game. When people ask you what games are fun, you will definitely say the games you have played, right? This is also the case.
Wang Lan of Sichuan Normal University has a master's thesis to share with you, "Study on the Sequence Effect in the Learning Process of Social Opposition Theory —— Taking Psychological Theory Learning as an Example", which was mentioned above.
Order will have a certain impact on people's understanding of information, and the information presented first has a greater impact on individuals than the information presented later.
To put it bluntly, I may have heard of xenon headlights, LED headlights, all kinds of strange matrix functions, and I have seen all kinds of pictures on the Internet.
But the halogen lamp comes first, which works well. I think it is good. There is no way. This happens.
Is halogen lamp really the best car light?
Is halogen lamp really the best car light? Technically, obviously not.
Ling Ming, Zhang Jianwen and others published a paper "The Development Trend of Automobile Lamps" in China Journal of Lighting Engineering, which said.
The same trend from A-class cars to E-class cars is that the use and market share of LED are increasing.
This is because LED has the advantages of no time delay, environmental protection and energy saving, long service life, low temperature, earthquake resistance and high color purity, and has become an inevitable substitute for tungsten lamps and halogen lamps.
To put it bluntly, halogen lamps are really good and classic, but the advantages of LED lamps are obviously greater, and it is only a matter of time before they are replaced.
Moreover, according to the analysis of TrendForce Jibang Consulting, in 2020, the penetration rate of LED headlights in passenger cars around the world has reached 53. 1%, more than half.
If LED headlights are placed on electric vehicles alone, the penetration rate is as high as 85%.
Even if it is a family car with a price of 65,438+10,000 yuan, only the lowest and second lowest will use halogen lamps now. Some generous cars, cars with higher and better configurations, are all LED headlights.
The halogen lamp used at the beginning is ok, and the feelings are added.
So in general, the reason why old drivers think halogen lamps are the best headlights is mainly because they used halogen lamps at the beginning of the car, which is a kind of emotional bonus.
In addition, halogen lamp is really a good choice, and it is still a good choice now, so it has a good natural impression.
