Why do you particularly recommend LED headlights for consumers?

LED semiconductor lighting network news When you buy a car, it seems that it will always be particularly sensitive to the configuration of the car's lighting. Many consumers will often see the ordinary halogen lamps on the car. Indeed, today, LED lights are so popular and developed, why is the collection of high-tech technology--the traditional halogen or xenon lamps used in cars? Today, the author will tell you what it is!

Let’s talk about the LED headlights especially for consumers. In fact, the use of LED lights has the following advantages!

1. Energy saving and low cost

The luminous efficiency of LEDs is 80% to 90%. 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.

2, long life

The LED components 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 100,000 hours, which is 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. And LEDs make the shape and lines of the headlights richer, and the recognition at night is higher.

3, small size, good durability

The LED components are simple in structure, compact and easy to arrange and design: this is a huge advantage of LEDs. This advantage fully meets the evolutionary needs of automotive manufacturers in design, breaking the constraints of the past lighting system on modeling innovation, with more creative Automotive products. It has excellent impact resistance and shock resistance, is not easily broken, and can be well adapted to various environments.

4, low brightness attenuation

The LED has high brightness and the brightness of the light is much lower than that of the halogen lamp. It is suitable for warning lights such as lighting and brake lights and turn signals.

Although LED has so many advantages, it is actually much better than traditional light sources. However, LEDs are electronic components, and the problem of heat is still a headache. For the civilian LED lights, the performance requirements are not high, the volume is not limited, the life is too good, so the civilian products can be made very cheap, of course, the products are quite expensive. For commercial use, the performance requirements are relatively high, so the materials of the LED lamps should be used well, which makes the overall cost of the LEDs increase.

Especially for the car's headlights, the car's headlight volume can be said to be fixed, but to achieve such a large luminous flux, so that only the power of the LED can be done, because the power per unit volume is too large, so that the heat dissipation of the LED The problem is particularly difficult to solve, only use a good LED lamp bead and reflector, and add a heat sink that has a good heat dissipation. However, because of the expensive materials, LED car lights are particularly expensive, and some low-end models are less willing to use them.

More importantly, in addition to my headlights Audi (and most good brands), many new cars claim to have LEDs, but in fact they are only installed on daytime driving, and the front and rear taillights are still ordinary xenon headlights. There are also new cars that claim to use LEDs for headlights, but in fact only the taillights are used. Some new cars claim that the headlights use LEDs, but in fact they are only LEDs for low beam, and the high beam is not. To upgrade the grade, the whole car should be LED, not just outside the car, but also include the interior atmosphere lights.

In summary, LED has many functions for automotive lighting. Only one or two LED lamps on a car are not considered to be LED lighting, but to fully utilize the excellent functions of LED automotive lighting, it is necessary to match the above various The new technology is worth a lot of money. At present, LED automotive lighting is still in the early stage of popularization, and it is far from being universal.
