What are the advantages of analyzing automotive LED headlights?

Since talking about LED, we must first talk about why it is so hot now, we all know that the current mainstream headlights in the car are nothing more than two categories: halogen headlights and HID xenon headlights (high-intensity discharge lamps), gradually emerging LEDs What advantages do headlights have over these two types of mainstream headlights?

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

1, energy saving, low cost: LED luminous efficiency of 80% ~ 90%, if we use our daily energy-saving lamps to compare, energy-saving lamps than energy-saving lamps 4 / 5, and LED energy-saving lamps are also energy-saving 1/4. In the car, the same daytime running lights, LED components consume only 1/20 of the halogen lamp. The cost of LED components has also dropped significantly year by year, and current costs and prices are still falling by more than 20% per year.

2, long life: the LED components currently used in automobiles can basically reach 50,000 hours, and well-known automotive lighting suppliers have been able to provide LED components with a lifespan of up to 100,000 hours, equivalent to 11 years... Considering the frequency of use of the lights, the LED components do not need to be replaced during the design life of the vehicle. In contrast, the life of the xenon lamp is only about 3,000 hours...

LEDs make the shape and lines of the headlights richer, and the night recognition is higher.

3, good durability: LED components are simple in structure, impact resistance, shock resistance is very good, not easy to break, can be well adapted to various environments.

4, LED components are small, compact and easy to arrange and design: This is a huge advantage of LED, this advantage fully meets the evolutionary needs of automotive manufacturers in design, breaking the shackles of the past lighting system for modeling innovation, let us have More creative car products.

5, fast response: LED lighting only needs microsecond level, can be quickly lit up on the taillights and turn signals to achieve better warning effect, used in the headlights, compared to xenon lamps and halogen headlights High response speed, better protection for driving safety.

6, low brightness attenuation: LED brightness is high, the light brightness attenuation is much lower than the halogen lamp, suitable for use as lighting and brake lights, turn signals and other warning lights.

7. Low-voltage DC can be driven, the load is small, the interference is weak, the requirements for the use environment are low, and the adaptability is good. A booster (high pressure pack) is not required like a xenon lamp.
