LED into daily life in many fields

The energy conservation gains more and more attention to the issue of carbon reduction for climate change. How to effectively reduce energy consumption become an important issue, with the birth of blue LED and white LED, the global traditional lighting is gradually replaced by energy saving LED, LED technology used in many areas to improve human life.

High-efficiency white LEDs are 20 times more efficient than traditional incandescent bulbs. According to the U.S. Department of Energy's statistics, conversion of conventional lighting to LEDs by 2030 can reduce 261 TWh of electricity. And approximately 30 power plants each save 1,000 MW of electricity, reduce 185 million tons of carbon dioxide emissions.

In addition, the LED 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 this year, the Zayed Future Energy Prize, affirming the positive impact of LED technology has on the world.

LED plant factories to ease the food crisis

The United Nations estimates that by 2050, the global population will reach 10 billion. By then, food production will have to increase by 50% to 60%. However, global warming affects soil and water resources, leading to uncertainties in the external environment.

Operators move their crops from the outdoors into the interior, combining the efficient use of LED and agricultural technology to build plant factories. The deployment of a variety of crops with different wavelengths of LED light, can accelerate its growth rate while increasing nutritional value, eliminating the interference of external environment. Benefiting from indoor growing technology, the Netherlands is the second largest exporter of food in the world. Its tomatoes produce more than six times the global average but consume less than 25 times the global average.

LED UV sterilization, to improve water pollution

With population growth, water pollution and water shortage are another major problem the world must face with. Nearly 850 million people worldwide lack basic daily water use, and about 500,000 people die each year from water pollution. Access to clean water is a challenge.

2018 Zayed Future Energy Prize Life Achievement Award Winner Nakamura Shuji said they are developing a UVC LED with a wavelength of 280 nm to kill waterborne pathogens in order to solve the water pollution problem. Although this UVC LED low power, efficiency is not high, but they believe in the end will be able to develop efficient equipment, and used in developing countries.
