Climate change has made the issue of energy conservation and carbon reduction increasingly important, and how to effectively reduce energy consumption has become an important issue. With the birth of blue LEDs and white LEDs, global traditional lighting has gradually been replaced by energy-saving LEDs. Used in a variety of fields to improve human life. Let's take a look at the related content with Xiaobian.
Efficient white LEDs are 20 times more efficient than traditional incandescent lamps, and the US Department of Energy estimates that traditional lighting converted to LEDs can reduce 261 TWh of electricity by 2030, saving approximately 1,000 MW of power for approximately 30 power plants. At the same time, 185 million tons of carbon dioxide emissions were reduced.
In addition, LEDs can be combined with solar energy to replace toxic and dangerous traditional coal lamps. LED technology also won the world-renowned renewable energy and sustainable development award, the Zayed Future Energy Prize, this year, affirming the positive impact of LED technology on the world.
The United Nations estimates that by 2050 the global population will reach 10 billion, when food production must increase by 50% to 60%, but global warming affects soil and water resources, leading to uncertainty in the external environment.
Some people move crops from the outdoors into the interior, combining efficient LED and agricultural technology to build plant factories. The blending of LED light of different wavelengths for various crops can accelerate the growth rate and increase the nutritional value, so as to avoid interference in 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 pollutionWith the population growth, water pollution and water shortage are another big problem that the world must face. Nearly 850 million people in the world lack basic daily water, and about 500,000 people die every year from water pollution. Achieving clean water is a challenge.
2018 Zayed Future Energy Prize winner of life award Nakamura said that in order to solve the water pollution problem, they are developing UVC LEDs with a wavelength of 280 nm to kill pathogens in the water. Although this UVC LED is currently low in power and inefficient, they believe that in the end it will be able to develop efficient equipment and use it in developing countries.
