According to the test results of IIHS, LED headlights have certain advantages in lighting safety, but well-made halogen headlights are not bad, and in rainy and foggy weather, halogen lamps have higher emission power and stronger penetration. Compared with halogen lamp, LED lamp has higher cost, higher brightness, better road coverage effect and lower color temperature of light source, belonging to cold white light.
The lighting effect is particularly good in a particularly dark environment. In addition, the color of objects in the illumination range is very close to the effect under natural light, which is convenient for drivers to see the details clearly. In addition, LED headlights generally have lens light distribution, which has good low beam paving effect, almost no blind area, and high beam light gathering is good. In practical use, the effect is stronger than halogen lamp.
The wavelength of LED cold white light source is generally short, and it is more likely to be scattered by particles or water droplets in the air in rainy and foggy days, which leads to the decrease of lighting effect. This is the lack of penetration. Due to structural problems, halogen lamps emit yellow light with low brightness, so they are called candle lamps.
When driving at night, drivers need to pay more attention and drive carefully to ensure driving safety. Because halogen lamps emit light by heating tungsten wire and halogen gas, a lot of heat energy will be generated in this process, which will affect the use of lamps.
If it is recycled continuously, it will have a certain impact on the life of the lamp, so the life of this halogen headlight is generally not very long. Compared with LED light source, it has the characteristics of energy saving, high brightness and long service life, and the brightness of LED light source can also be adjusted according to the driving situation.
Because LED lamps use semiconductors as materials, they can emit different colors depending on the semiconductor materials used. Therefore, they can be used as various types of lights, such as red brake lights and yellow turn signals, and LED headlights will be better. The main difference between car headlights LED headlights and halogen lamps is brightness.
The brightness of LED headlights can meet the needs of driving at night, and the brightness will be wider and the driver's vision will be better. LED headlights have strong illumination brightness, but the penetration is not enough in rainy and foggy days, which will cause interference to drivers, while halogen headlights have strong penetration and are safer to drive in rainy and foggy days.
The service life of LED lamps is greatly influenced by temperature. LED lamps with poor heat dissipation will definitely not reach the theoretical service life of 30,000 hours. In addition, low-priced products often adopt the design of double-sided light, which leads to the great difference between the shape and structure of lamps and lanterns and the original factory.
Because of the longer life and better light quality, the proportion of LED headlights is increasing, and what kind of lights to choose depends on the actual situation. Please don't blindly look for high-brightness LED lights, drive at high speed, and the most important thing is safety. Running at high speed in sunny weather is a pleasure.
Plenty of sunshine makes every place look bright, with a good view, and it is naturally safer to drive. In addition, different headlights have their unique uses, so we should learn to use them. Many car owners will turn on the danger warning light no matter what happens. If the weather is heavy rain and fog, using fog lights is the best choice.
