Regarding prolonging the life of car lights, there is an experience in the shop that when changing the lights, wipe the new bulbs with alcohol. Is this experience reliable? In fact, there is some truth, because when the repairman changes the light, he usually installs the lights with his bare hands or with tools, so it is inevitable to leave fingerprints, oil stains, sweat stains and so on on the glass of the lights. When the car lights are on, the working temperature is still very high. The uneven grease left on the surface of the car lights will cause uneven heat dissipation of the bulbs, resulting in local overheating and shortening the life of the bulbs.
In addition to the above experience, there are some principles you should also know, such as: 1. Try to choose reliable and high-quality car lights, resist inferior and fake car lights, and try not to switch the lights too frequently. After all, Not equal to keyboard keys. 2. Do not change the original car lights casually, because the service life of the car lights has a lot to do with whether the current is stable. Refitting the car lights will inevitably involve circuits. If the conversion is performed unprofessional, it is likely to greatly reduce the service life of the car lights and bring safety hazards. 3. Regardless of any type of bulb, it is best to check every 30,000 kilometers.
There is no uniform statement about how long the life of the car lights is. The key depends on the type and quality of the car lights. There was a data obtained by a special research association that the service life of ordinary halogen car headlights is only 500 hours, which is less than 42 nights. Based on this data, we can conclude that if the car headlights are turned on 24 hours a day, they can only be used for 21 days. Of course, you don’t have to wait for the lights to turn on when you change the lights. You need to replace them when the brightness is ignored or dimmed.
The life of the xenon lamp, which is becoming more and more popular now, is much longer, generally reaching 2500~3000 hours. That is to say, if the xenon lamp is turned on 24 hours a day, the xenon lamp can be used for 2500 hours/24 hours=100 days, the lighting effect Well, of course the price is higher.
LED car lights are more demanding. LED lights are a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. In theory, its service life can be as long as 100,000 hours, but after being made into a car light, the general service life is 20,000 hours, which means that if you turn on 24 hours a day, LEDs can also be used for about 800 days. Of course no one will turn on the headlights 24 hours a day. LED car lights are brighter, more energy efficient, more beautiful, and of course more expensive. Another fatal weakness of the LED lamp is that it needs a continuous and stable DC current, and once the rated value is exceeded, the life will be greatly shortened. For this reason, basically each lamp has a dedicated electronic drive circuit, and this drive is the whole The short board of the lamp, more than 99% of the failures are caused by it, and the maintenance cost is not low.
The above is about the life-related issues of the car headlights. Of course, replacing the headlights is a small matter. If it is broken or dim, please don’t be stingy and replace it in time. Safety first.
