For a long time in the future, China's energy structure will be dominated by coal, and saving electricity is equivalent to reducing coal consumption. If energy-efficient LEDs are popularized in China, lighting power consumption is expected to fall by more than half. At the same time, LED lighting, as part of social public facilities, can play a very important role in reducing smog.
Efficient lighting helps reduce PM2.5 emissions
It is estimated that electricity consumption for lighting accounts for about 20% of the total electricity consumption of the whole society. Last year, China's total electricity consumption was 552.3 billion kWh, and the electricity consumed by lighting conversion reached 1.1 trillion kWh.
Kaveh Zahedi, executive director of the UNEP Regional Office for Asia and the Pacific, said in an interview with the media that the promotion of efficient lighting is of great significance to countries that rely on fuel imports for power generation, helping to reduce electricity consumption. Haze and carbon emissions, reduce electricity bills, and thus reduce the construction of thermal power plants.
LED lights are more energy efficient
It is understood that many people choose to use energy-saving lamps after the incandescent lamps are eliminated. LED lights are more energy efficient than energy-saving lamps and have a longer life. If energy-efficient LEDs are popularized in China, it will be expected to reduce lighting power consumption by more than half, which is more significant than energy-saving lamps. The LED lights themselves are also undergoing continuous energy efficiency upgrades. Taking outdoor lighting as an example, current LED lights can save at least 50%.
Cost-effective is the key to universalization
Under the smog, the most basic and most important thing in lighting protection warfare is to create cost-effective LED lighting products. The popularity of LED lighting has been rapidly increasing in recent years. The newly added municipal lighting engineering, home improvement, hotel, commercial lighting and other applications are mainly LED-based. It is expected that the inventory of LED lamps will exceed traditional energy-saving lamps within two years. Continuous introduction and use of innovative technologies, such as the use of thermally conductive engineering plastics instead of high-energy metal aluminum as a heat sink, can effectively reduce the carbon footprint of the product. At the same time, the reduction in product weight can also reduce transportation costs and energy consumption, and even the use of bio-based materials has been recognized by the industry's leading customers.
In fact, how to put energy-saving measures throughout the entire electrical design process is particularly important: for manufacturers, the rational use of new materials and new technologies; for designers, to enhance the environmental awareness of electrical engineers in design, to rationally select efficient Electrical equipment, including transformers, motors, cables, lighting sources, intelligent control systems, etc.; for the majority of users, is to effectively save energy in daily management and life.
