How long do car headlights last for? This has to do with the type of lamp.
First of all, the most common halogen headlights, basically family cars are this, and its principle is to inject iodine or bromine and other halogen gas into the bulb, sublimated tungsten filament and halogen at high temperature for chemical action, and then cooling, tungsten will be solidified again in tungsten filament, repeated cycles and produce such a situation.
This process of regeneration makes halogen lamps last four times longer than household incandescent lamps. Generally, the life of halogen lamps is 300 to 500 hours.
If you drive for an hour every day, you will have to change the light bulb in more than a year. After the normal life period, the brightness of the lamp will become dimmer and dim until it is completely unbright.
The second is slightly more advanced, but now it is also available in many cars, called xenon lamps.
This is also called HID gas discharge headlamp, it is wrapped in quartz tube high-pressure xenon, replacing the traditional tungsten wire we just said, with high-voltage current to activate xenon gas, forming an arc light, between the two poles can continue to discharge light, service life and halogen lamp, about ten times higher.
Xenon lamps require 3.5 amperes of current to work, with a service life of about 2500 to 3000 hours. It is said that Philips has a standard that the light decay cannot exceed 30% after 2250 hours, for your reference.
Just talked about the car bought itself has xenon, many friends are halogen lamps themselves modified into xenon lamps, then additional need to add a stabilizer.
The stabilizer not only affects the performance of the lamp, but also affects the life. If you have this stabilizer for two or three hundred dollars, install a xenon lamp, and basically use it for 500 hours after the light decay will reach more than 30%. Therefore, if you change it, everyone understands that it is similar to the life of the halogen lamp, and it is brighter.
Another more expensive, LED headlights, often more expensive cars, or relatively high configuration will have this thing.
LED has a long service life, generally 60,000 to 100,000 hours, is really very durable, and if it is used for 30,000 hours, the light decay will not exceed 5%, long life and not easy to darken.
Basically, if nothing is broken or broken, the service life of this lamp is the same as that of the whole car. So you see that it is expensive, and it still makes some sense.
However, LED lights are not very suitable for long-term lighting, because its heat dissipation is not very good, and the heat dissipation of the lamp is not good, and it is easy to produce temporary or permanent light decay. Therefore, friends who change LED headlights should pay a little attention, not simply change the lights, and the heat dissipation scheme should also be considered.
The life of these lights just mentioned belongs to the category of physical life, and there is another called warranty life.
Because the lamp is a wearing part, the manufacturer's maintenance manual will generally be written in small print, the whole car three-year warranty, but the headlights often only have 3 to 6 months or 5,000 kilometers of warranty. After this time, you paid for it yourself. Don't think that buying a car, the headlights can be replaced after two years of broken headlights, there will be no such thing.
Today I will talk to you about car headlights, not only to understand it, the car every six years is not to be inspected last year, but to carry out light inspection, angle, brightness and this aspect. If you just get close to the decline period of the headlights and do not qualify, it will delay normal work and life.
Therefore, you can also pay attention to it, according to the type of headlights of your car, to predict when it is time to check the lights and replace the bulbs.
