LED lights use cold light sources, with low glare, no radiation, and no harmful substances during use. The working voltage of LED is low, it adopts DC drive mode, ultra-low power consumption, electro-optical power conversion is close to 100%, and it can save more than 80% energy than traditional light sources under the same lighting effect. The service life can reach 3-5 years, which can greatly reduce the maintenance cost of the lamp and avoid the pain of frequent lamp replacement. LED has better environmental benefits. There are no ultraviolet and infrared in the spectrum, and the waste is recyclable, can be touched safely, has no pollution, and does not contain mercury. It belongs to the new era of energy-saving green lighting sources.
