For cars, LED light sources (not limited to headlights) have the following 7 advantages:
1, energy saving, low cost: LED's luminous efficiency of 80% to 90%, if you use our daily energy-saving lamps to compare, energy-saving lamps than the incandescent lamp energy-saving 4/5, and LED energy-saving lamps than energy-saving 1/4. In the car, the same daytime running lights, LED components consume only 1/20 of the power of halogen lamps. The cost of LED components has also been greatly reduced year by year, and current costs and prices are still falling by more than 20% per year.
2, long life: LED components used in the car can basically reach the level of 50,000 hours, and well-known automotive lighting suppliers have been able to provide the life of up to 100,000 hours of LED components, conversion, equivalent to 11 years. Taking into account the frequency of use of lights, LED components do not need to be replaced during the entire design life of the vehicle. In contrast, the life of a xenon lamp is only about 3,000 hours. And LEDs make the shape and lines of headlights richer and the nighttime recognition higher.
3, good durability: LED element structure is simple, impact resistance, shock resistance is very good, not broken, can be well adapted to various environments.
4, LED components small size, compact and easy layout and design: This is a huge advantage of LED, this advantage fully meets the automotive manufacturers in the design of the evolutionary needs, breaking the shackles of the past lighting system on modeling innovation, let us have More creative automotive products.
5, fast response: LED lights only microsecond level, used in the taillights and turn signals can quickly light up to achieve a better warning effect, used in the headlights, compared to xenon lamps and halogen headlights have more The high response speed provides better protection for driving safety.
6, low brightness decay: LED brightness is high, the light brightness decay is much lower than the halogen lamp, suitable for lighting and brake lights, turn signals and other warning lights.
7, low-voltage direct current can be driven, the load is small, weak interference, low requirements for the use of the environment, good adaptability. Unlike a xenon lamp, it requires a booster device (high voltage package).
