Since we are talking about LED, we must first explain why it is so popular now. As we all know, the mainstream headlights on cars are mainly divided into two categories: halogen headlights and HID xenon headlights (high-intensity discharge lamps). What are the advantages of the gradually emerging LED headlights compared to these two mainstream headlights?

For cars, LED light sources (not limited to headlights) have the following benefits:

1. Energy saving and low cost: LED has high luminous efficiency, nearly twice that of fluorescent lamps. If we use our daily energy-saving lamps as an analogy, energy-saving lamps are 4/5 more energy-efficient than incandescent lamps, while LEDs are 1/4 more energy-efficient than energy-saving lamps. In cars, the energy consumption of LED components for the same daytime running lights is only 1/20 of that of halogen lamps. The cost of LED components has also been significantly reduced year by year, and currently the cost and price are still decreasing at a rate of over 20% per year.

2. Long lifespan: Currently, LED components used in cars can reach a level of 50000 hours, and well-known automotive lighting suppliers can already provide LED components with a lifespan of 100000 hours, which is equivalent to 11 years Considering the frequency of light usage, LED components generally do not need to be replaced throughout the design lifespan of the vehicle. In contrast, the lifespan of xenon lamps is only about 3000 hours.

3. Good durability: LED components have a simple structure, excellent impact resistance and shock resistance, are not easily broken, and can adapt well to various environments.

4. LED components are small in size, compact and easy to arrange and design: This is a huge advantage of LED, which fully meets the evolutionary needs of automotive manufacturers in design, breaking the constraints of past lighting systems on design innovation and allowing us to have more creative automotive products.
