The use of high-brightness LED lighting will become the main features of future cars, thanks to LED compared to traditional incandescent lighting program has many of the basic advantages.Such as quick response,no radiate,no strobe.

In addition, LED lighting can also be driven by automotive design technology and design style change. However, just as, like any innovative technology, LED lighting in the car before being widely used, still need to overcome many difficulties.

Key Features:

1.Reliability and service life of LED's expected service life of 50,000 hours, and halogen lamps to 20,000 hours, tungsten incandescent lamp to 3 thousand hours. Compared to incandescent lamps, LED's rugged, less susceptible to vibration, the use of a coherent state does not significantly decrease the output brightness. Multiple LED based lighting solutions also offers a "redundancy" benefits, even if one LED fails, you can still continue to use the lighting device. Proper use of LED (LED Special is the right temperature control), can effectively extend the LED life expectancy. Conversely, if the temperature is too high, LED is very easy to damage. LED lighting applications in the car on the legal definition also involves many issues. Most countries on the brake lights or headlights on or off lights failure clearly defined. But with multiple LED lights, is difficult to accurately define whether light damage. Manufacturer and legislative bodies are defined LED is used.

2.Efficiency / lumens per watt than standard incandescent lamps, LED consumption per unit of electrical energy can produce more light output. However, when compared with halogen lamps, LED light output of the real advantage is not obvious. The latest LED lumens per watt with outstanding value, but some values are obtained under the optimized conditions, and are usually not obtained under conditions of maximum output. Generally speaking, when the LED current increases, light output does not increase linearly. Therefore, even if LED at 0.5A current output x lumens, it will not output current 1.0A 2x lumens.

3.Response to brake lights and direction indicator tube as an example, assume that the vehicle speed is 125 km / h, or 35 m / s, the incandescent hot start time is about 250 milliseconds, and responsive LED may be early about 8 meters away from the brake warning issued to avoid collision. Light as well.

4.Another key feature is the LED directional light-emitting means. And incandescent different, LED light only through a surface, which charts lamp headlights and application of good, but may not be suitable for car lighting other lighting applications.
