The benefits of LED light source application in automotive lighting

Everyone says that the eyes are the windows of the soul, and in the case of cars, there are a pair of beautiful headlights, just like having a beautiful pair of scorpions. The appearance of LED car headlights is like giving the headlights a "beauty", and the "eye" charm index is directly raised to a level, and its function is changing with each passing day. I think it is time for everyone to understand the LED car. The headlights are gone. There is a very common Chinese name for LEDs called light-emitting diodes, which now appear in light boxes, signboards, displays, and the role of various electrical lights and backlights, while in car taillights, high-position brake lights, and daytime trips. An important part of the headlights.

Where is the LED car headlights?

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 gas discharge lamps), and the advantages of the emerging LED car headlights compared to these two types of mainstream headlights. What? For cars, LED light sources (not limited to headlights) have the following benefits:

1. Energy saving and low cost: LED has high luminous efficiency, which is nearly twice that of fluorescent lamps. If we use our daily energy-saving lamps for analogy, energy-saving lamps can save 4/5 more energy than incandescent lamps, and LEDs can save 1/4 more energy-saving lamps. 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 the level of 50,000 hours, and well-known automotive lighting suppliers have been able to provide LED components with a life of up to 100,000 hours, taking into account the frequency of use of lights, basic 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...

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.
