LED use low-voltage power supply, the supply voltage between the DC 3-24V, depending on the product varies, there are a few DC36V, DC40V, etc., so it is a more secure than the use of high-voltage power supply, especially for public places.
Consumption of energy than the same effect of incandescent light reduced by about 80%, more than 40% less energy-saving lamps.
The volume is very small, each unit LED small piece is 3-5mm square, it can be prepared into a variety of shapes of the device, and suitable for volatile environment
100,000 hours, the light failure for the initial 50%
The response time of the incandescent lamp is millisecond, and the response time of the LED is nanoseconds
Does not contain harmful metals such as mercury
Light-emitting diode easily through the chemical modification method, adjust the material band structure and band gap, to achieve red, yellow, green and blue orange multi-color light. Red tube operating voltage is small, the color of different red, orange, yellow, green, blue LED working voltage in turn increased.
LED prices more and more civilians, because of the characteristics of LED power, perhaps in the near future, people will replace the incandescent LED lights. China's part of the city roads, schools, factories and other places have been decorated for LED lights, energy-saving lamps.
