To put it bluntly, he couldn't see clearly, and it also affected the vision of the other vehicle's personnel. At the same time, poor workmanship makes LED lights unable to effectively dissipate heat during operation, resulting in early light decay and shortened life. The most important thing is that poor quality lights greatly affect driving safety and vehicle circuit systems.

So how to choose LED lights?

Step 1: Look at the color temperature

Color temperature: It is a physical quantity used to define the color of the light source in lighting optics. It refers to the color change felt by the human eye under different energies of light waves, which refers to the color of the light. This can be seen directly from the parameter box. The more blue the light color, the higher the color temperature; the redder the lower the color temperature.

3000K yellow light, strong penetrating power; 4300K white with yellow, balanced brightness penetration; 5000K light is completely white, which is the highest color temperature of the European standard; 6000K light is completely white, slightly bluish; 7000K white is obviously bluish ;Blue light above 8000K.

Therefore, it is more suitable to choose LED headlights with a color temperature between 4300K-6000K, which takes into account both brightness and penetration. It can not only meet the needs of night driving lighting, but also do not need to worry about the penetration of light in rainy and foggy weather.

Step 2: Look at the heat dissipation

Heat dissipation: The heat dissipation of the lamp determines the life of the lamp. After the LED light source is energized, about 35% of the electrical energy is converted into light energy, and the rest is converted into heat energy.

The active cooling method is equivalent to speeding up the air convection speed. Yes, it is the fan cooling!

This heat dissipation method is to add a small fan at the tail of the LED. When the LED is just lit, the small fan at the tail also works together, and the heat of the aluminum seat is dissipated into the air through the fan in the form of air convection. .

The third step: lamp beads, substrate

In the case of led car lights, it is mainly the lamp beads that emit light. The quality of the lamp beads is related to the quality and effect of the entire LED.
