Advantages of LED energy-saving retrofit in contract energy management

At present, more and more LED lamps are replacing traditional lighting fixtures and are used in lighting display, advertising lighting, underwater lighting, architectural lighting, street lighting and other applications.

The Chinese government has adopted "energy saving and emission reduction" as a national policy. With the in-depth development of the national “energy saving and emission reduction” project, “Green Lighting Project” has been listed as a key promotion project in China and a cross-century strategy for energy conservation industry. China's lighting industry has stepped into the watershed of industrial upgrading. In the context of calling for energy saving and emission reduction, high-efficiency and energy-saving LED products are the focus of an industrial upgrade. They are called "the beginning of a new revolution in the field of lighting", which integrates environmental protection, long life, high efficiency, high color rendering, No stroboscopic, no UV, no mosquitoes, instant start, wide voltage working range, large width operating temperature range and many other advantages. Its environmentally friendly advantages are the leaders in energy-efficient lighting products. If 10% of the traditional light source in China is replaced by LED every year, it can save 9 billion kWh, equivalent to 8.64 million tons of carbon dioxide emissions. At present, LED lighting products have also penetrated into various fields of social life. The following is a comparison of several commonly used lamps and LED lamps to quantify the advantages of LED lamps.

It is easy to see from the above table that the LED lamp is 1/10 of the power consumption of the incandescent lamp. For energy-saving lamps or fluorescent tubes that are currently used in large quantities, the energy-saving efficiency is also more than 50%, and mercury, which is a harmful and harmful substance in energy-saving lamps or fluorescent tubes, is completely avoided. A 36w fluorescent tube crushing may cause the mercury vapor content in the surrounding air to exceed 2000 times the national standard; and some scrap lamps are improperly handled, and the contained mercury penetrates into the ground, and every milligram of mercury can pollute hundreds of tons of water. It is also a huge damage to the ecological environment. LED lights can not only face the increasingly serious energy crisis, but also provide an important way for the purification of the ecological environment. Therefore, the potential of LED lighting in energy-saving retrofits is enormous.
