Now LED headlights and even laser headlights are becoming more and more popular in the headlight modification market. And many car headlights are getting brighter and brighter. Many consumers even blindly distinguish the quality of car headlights through the brightness of lights. In fact, this is a huge misunderstanding. So what kind of car headlights meet the daily use standards and how to use them correctly?
1. Different headlights have different prices.
Halogen lamps, xenon headlights, LED headlights and laser headlights.
The earliest halogen lamps were developed after the upgrading of incandescent lamps. By injecting iodine or bromine into the bulb, the tungsten wire becomes stronger under chemical reaction, so as to achieve longer service life. Most of them are currently equipped with some entry-level models. The utility model has the advantages of simple structure, low cost and strong penetration.
However, the brightness of halogen headlights is low. In order to solve this problem, xenon headlights came out. The efficiency of converting electric energy into light energy is 70% higher than that of halogen lamp, and the brightness is more than 2 times higher. However, it must be used with the projector lens, and it also has the disadvantages of long start-up time, short service life and high cost.
Since then, the emergence of LED headlights has made a qualitative leap in automobile headlights. Higher brightness and lower energy. At the same time, the smaller size and structure also enable the headlights to serve the body modeling. However, LED headlights need higher heat dissipation and higher price.
Finally, laser headlights. At present, it is only used in Audi and Rolls Royce. Their light-emitting elements are laser diodes, which have many similarities with LED light-emitting diodes. The lighting range can reach 600 meters. But the high price discourages many consumers.
Brighter headlamp lenses are not the best.
2. Brightness is not unique.
Brightness is only one of the aspects that need to be considered. We also need to consider lighting effect, ground clearance, lighting area, heat dissipation, etc. Generally speaking, most LED headlights have met the brightness requirements. But people with special needs can choose to refit their headlights. In order to balance the cost, the original headlights are generally difficult to meet.
In addition, more and more drivers realize that too high brightness will be counterproductive and affect driving safety. Some luxury models equipped with laser headlights must be turned on in the weak light environment when the vehicle speed is higher than 80km / h. At the same time, there will be corresponding occlusion adjustment when encountering a car.
3. Which do you need?
3.1 long term driving in urban areas.
Street lights in urban areas can provide enough light, so you don't need to update them. Only use the original halogen headlights. Generally, halogen headlights are enough, but too bright lights will blind the driver's eyes and affect driving safety.
3.2 long term driving in suburbs.
Due to the weak light in the suburbs, xenon or LED headlights with higher brightness can be selected when driving in the suburbs. However, you must update the headlights with the projector lens.
Headlight modification with projector lens and led shield.
4. Which is better? 5000K？ 6000K？ 8000K？
The high temperature has great brightness, and the high temperature bulb has beautiful colorful lights. However, high-temperature lighting does not work in foggy and rainy days.
Whether you need to replace the headlights depends on your car. When selecting headlights, make sure you understand the advantages and disadvantages of each type of headlight.
