A friend asked whether the original car's headlights were halogen, which lit up yellow. It was fine when driving in the city because of the street lights on the road.
There are many auxiliary light sources in various stores and so on, and the brightness is not a problem. However, when you get to national highways, provincial highways, or highways, some have no street lights.
Or in places where the street lights are relatively dark, the brightness defects of halogen headlights are highlighted. If you want to modify the headlights, is it better to replace them with LED ones or xenon headlights?
Let's talk about their respective advantages and disadvantages, and then compare them. First of all, LED has a longer lifespan than xenon headlights.
The LED lamp is fixed on a bracket with a semiconductor chip that is energized to emit light, and then sealed. Its stability is better than that of xenon lamps.
Judging from current technology, the luminous efficiency of LED lights is better than that of halogen and xenon lamps, and the brightness of LED lights will not attenuate.
As the xenon bulb is used for longer and longer, its brightness will attenuate. It is easier to install an LED. Now many LED lights can be installed without damage.
Just plug it directly into the original car's interface, but xenon headlights need to be installed with a ballast. The ballast instantly converts the 12V voltage on the car into 23,000V.
In this way, xenon and other inert gases in the bulb can be activated to emit strong light. Therefore, xenon lamps are relatively more dangerous than LED lamps.
If the products used are unqualified, or the construction and installation are not standardized, there may be a risk of spontaneous combustion in the future. Does this mean that LEDs must be better than xenon lamps when modifying headlights?
Yes, LEDs also have shortcomings. The biggest disadvantage is heat dissipation. There are two ways of heat dissipation for ordinary LED light bulbs. One is behind the butt of the light bulb.
There is a cooling fan that will rotate as long as the headlights are on. Friends who have replaced this kind of light bulb can hear the fan working after you turn on the lights.
The other is the heat sink, which is just like the principle of the heat sink in a car. No matter what kind of heat dissipation is used, the heat is taken away from the butt of the lamp.
But think about it, the headlights are inside the engine compartment. When the engine is working, the temperature in the cabin itself is very high, which affects the heat dissipation of the headlights.
If the quality of the LED lamp used is not up to standard, it may melt the back shell of your headlight. Please pay attention when modifying the light.
Whether it is LED or xenon, you need to check the irradiation range of the light. If you do not install a lens, you just replace it with an LED bulb or a xenon bulb.
Then this is not possible. There are specific requirements for the light shape of the headlights, height, the intersection line between light and dark of the high and low beams, the maximum luminous intensity point of the high beam, etc.
You can't just change a light bulb, otherwise you will be fined if you are caught by the traffic police while walking on the road, so when you modify the lights,
Whether it is LED, xenon, or the now popular laser headlights, you need to find professionals to make them properly in accordance with national standards.
When modifying lights, you should also consider the penetrating power in rainy and foggy weather. Generally speaking, the higher the color temperature, the worse the penetrating power. The color temperature of general halogen lamps is 3000K.
The penetrating power is very good. LED is generally 5000K. If it looks a bit white, then its penetrating power is not good. In this regard, I think xenon lamps are most suitable.
Xenon lamps have a color temperature of 4300K, which is brighter than halogen and has stronger penetrating power than LED. If there is no separate front fog lamp in the car, when choosing the light bulb, be careful not to use one with a color temperature that is too high.
Don’t use ones that look whitish or even bluish, so in general, if you want to modify the lights and don’t travel on some national and provincial highways, a better halogen bulb will suffice.
If you just want to upgrade, I personally suggest that a 4300K xenon lamp with a lens is enough. It is fine for driving in rainy and foggy days. Finally, everyone remembers that no matter what kind of lamp is changed, it must not be a high-beam dog. Thank you everyone for your help. focus on
