Advantages of car led headlights:

1. Long life span, generally up to tens of thousands or even 100,000 hours. Some people think that if LEDs are used in car lighting in the future, there will be no need to replace lamps throughout the life of the car.

2. High efficiency and low energy consumption. The LED light source can directly produce the red, amber and other colors required by the car lamps without color filtering, without loss, and the power utilization rate is as high as 80%.

Disadvantages of car led headlights:

1. The cost is high. Taking LED reversing lights as an example, an LED reversing light is nearly 30 yuan, while the price of a bulb is only 3 yuan, most of which is the cost of the LED light. The high price makes ordinary cars unable to install LED lights, and the market cannot be promoted.

2. LED car headlights are difficult to popularize, heat dissipation is not good, and poor heat dissipation is easy to light decay. Affect the service life of car lights.

Extended information:

LED can directly convert electrical energy into visible light, and the conversion efficiency is relatively high. Many luxury brands use full LEDs as the light source of the headlights, and after market advancement, more brands are also delegating LEDs to the small car market. Under the market trend of energy saving and environmental protection in the future,

LED light sources are likely to become mainstream.

The energy consumption of the LED light source is only 1/20 of that of the halogen lamp, and the lifespan can reach more than 100,000 hours. Basically, the car lights can be used normally when the car is scrapped. Compared with the xenon headlights, the volume is smaller and can be lit instantly. Bright, it is very safe for driving safety, but the LED light source has very high requirements for heat dissipation and ventilation.
