The Features of LED Light

LED is light-emitting diode. LED light adopts leds as the main light source. It has advantages of long lifespan, low power consumption, fast response, small volume, adjustable and controllable light and environmental protection.
 

1.Low power consumption
LED is a low voltage device. Therefore, the power consumption is minimum in the same brightness, which can greatly reduce the energy consumption. With the development of technology and material, it will have a higher luminous efficiency. If Japan  all apply  LED lights, it can reduce two large nuclear power plants. It is beneficial to environmental protection

2.Long Lifespan
As a conductor solid light emitting device, LED has longer lifesapn compared to other light emitting device. It usually can reach 10,000 hours. If you replace the traditional car light, the lifespan of LED light will be longer than the lifespan of the car. It has the feature without replacement in its whole life.

3. Fast Response
LED can generally response in the tens of milliseconds ( NS ). This is better than other light sources. If we make the automobile brake with the LED lights at high speed, it greatly improves the safety of the vehicle.

4.Small Volume
This is the characteristics of semiconductor solid device. We can make clear display device with the leds.

 

5.There are no pollutants when we use LED lights, such as mercury, lead and so on. So people call the LED light source as the " green" light source.
 

6. Adjustable and Controllable Light
As a light emitting device, the brightness of LED light can be controlled by changing the current. We can also adjust the different wavelength of LED to achieve color change. At present, LED lights are widely applied in the large screen color display.
