LED will become the mainstream energy-saving light source it?

Single LED power is very small, generally only 0.03 ~ 0.06 watts, due to low drive voltage, current is small, the light emitted is naturally very weak, can not be used for lighting. However, LED has a high luminous efficiency, which is the same brightness of light, it consumes less electricity than other traditional lamps, this advantage is in full compliance with the direction of energy-saving low-carbon. By building a few, a dozen or even dozens of tiny LED light emitting devices, people can emit light that is as bright as a single incandescent or fluorescent light. This practical LED lamp can save more than 50% energy compared to the energy-saving lamps with the same brightness. With the advancement of technology, it will surely win the "future light source".

Because the LED is a solid direct light, the structure is simple and strong, there are no wearing parts, heat loss is low, and life is particularly long. Theoretically, the life of a single chip can reach 100,000 hours, but the actual application of LED lamps and lanterns is often a series and parallel combination of dozens of chips, and also with a power supply, so the combined LED lamp life of about 50,000 hours. Even so, it is much longer than the life of incandescent lamps (about 1,000 hours) and energy-saving lamps (about 10,000 hours).

LED basically has no pollution to the environment, strong adaptability to the environment, can also be freely combined, and the display effect is extremely contagious. These advantages enable LEDs to replace a wide range of conventional luminaires and are suitable for lighting in almost all indoor and outdoor environments and in different areas. LED can be combined with the Internet of Things and cloud computing technology to achieve the "adaptive lighting" goal. Therefore, LED is also known as the new light source of the century and is one of the most promising high-tech fields in the 21st century.
