LED is a semiconductor chip, which emits light by electronic movement, and the conversion efficiency can reach 68%. In contrast, the light emission of ordinary light bulbs is converted from electrical energy to thermal energy and then to light energy, and the conversion efficiency is only 12%.
Because of this, LED has unparalleled energy saving and environmental protection advantages of other light sources. Under the same lighting effect, the power consumption of LED is only 1/10 of that of ordinary bulbs, and the service life is 100 times longer than ordinary bulbs. In the field of special lighting, landscape lighting (replacement of neon lights) can save energy by 70%, and traffic signal lights (replacement of incandescent lights) can save energy by 80%.
In addition, because the LED uses a cold light source, there is little glare, no radiation, no harmful substances are emitted during use, and waste can be recycled without pollution.
