Multi-field applications of LED technology can improve human life
Climate change makes the issue of energy saving and carbon reduction more and more important. How to effectively reduce energy consumption has become an important issue. With the birth of blue LED and white LED, global traditional lighting has gradually been replaced by energy saving and power saving LEDs. Used in many fields to improve human life.
High-efficiency white LEDs are 20 times more efficient than traditional incandescent lamps, while the U.S. Department of Energy estimates that conversion of conventional lighting to LED by 2030 will reduce electricity by 261 TWh, and that about 30 power plants will save 1,000 MW each. At the same time, it reduced 185 million tons of carbon dioxide emissions.
In addition, LEDs can be combined with solar energy to replace the toxic and dangerous traditional coal light. LED technology also won the world-renowned Zayed Future Energy Prize for renewable energy and sustainable development this year, affirming the positive impact of LED technology on the world.
LED plant factory, ease food crisis
The United Nations estimates that by 2050, the global population will reach 10 billion. By that time, food production must increase by 50% to 60%. However, global warming will affect soil and water resources, causing uncertainty in the external environment.
Businesses move crops from the outdoors into the interior, combine efficient LED and agricultural technologies, and build plant factories. The deployment of different wavelengths of LED light for a variety of crops can accelerate its growth rate while increasing nutritional value, eliminating interference from the environment. Thanks to indoor planting technology, the Netherlands has become the world’s second largest food exporter. Its tomato production is more than six times the global average, but its water consumption is 25 times lower than the global average.
LED UV sterilization to improve water pollution
As the population grows, water pollution and water shortage are another big problem that the world must face. Nearly 850 million people in the world lack daily basic water, and about 500,000 people die from water pollution every year. Obtaining a clean water source is a major challenge.
2018 Zayed Future Energy Prize winner of the Zayed Future Energy Prize, Nakamura said that in order to solve water pollution problems, they are developing UVC LEDs with a wavelength of 280 nm to kill pathogens in the water. Although this UVC LED has low power and low efficiency, they believe that it will eventually be able to develop high-efficiency equipment and make it available to developing countries.
