When it comes to LED, we must first talk about why it is so fire, we all know that the current mainstream car headlights no more than two categories: halogen headlamps and xenon lamps (high-intensity gas discharge lamp), the gradual rise of the LED lights Compared to these two mainstream headlamps What are the advantages?
LED light source (not limited to headlights) has the following advantages:
① energy saving, low cost: LED luminous efficiency is high, nearly two times the fluorescent lamp. If we use our daily energy-saving lamps to the analogy, energy-saving lamps energy-saving than incandescent 4/5, and energy-saving lamps than the energy-saving LED 1/4. In the car, the same daytime running lights, LED components, energy consumption is only halogen 1/20. The cost of LED components has been greatly reduced year by year, and the current costs and prices are still more than 20% annual rate of decline.
②, long life: the current 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 life of 100,000 hours LED components, conversion, equivalent to 11 years. Taking into account the frequency of use of lighting, basically in the design life of the vehicle, LED components do not need to be replaced. In contrast, xenon lamp life of 5000-10000 hours or so
③, good durability: LED components, simple structure, impact resistance, shock resistance is very good, not broken, can be well adapted to a variety of environments.
④, LED components, small size: This is a great advantage of LED, this advantage fully meet the automotive manufacturers in the evolution of the design requirements, breaking the light system constraints on the shape of innovation, let us have more innovative automotive products.
With the current LED and HID xenon lamp production costs continue to dropping and have a better technical characteristics, has more and more car dealers into this change. I believe that soon LED and HID xenon lamp will be popular in the everyday home economy car up for our lives more convenient.
