The LED is a semiconductor chip that emits light by electrons and has a conversion efficiency of 68%. In contrast, the illumination of an ordinary light bulb is converted from thermal energy into thermal energy and converted into light energy, with a conversion efficiency of only 12%. Because of this, LEDs have unparalleled energy saving and environmental advantages. Under the same lighting effect, the LED consumes only 1/10 of the power of an ordinary bulb, and its service life is 100 times longer than that of an ordinary bulb. In the field of special lighting, landscape lighting (replacement of neon lights) can save 70%, and traffic lights (instead of incandescent lamps) can save 80%. In addition, since the LED uses a cold light source, there is little glare, no radiation, no harmful substances are emitted during use, and the waste can be recycled without pollution.
