Three light source impact on human life in twenty-first Century was named LED

[LED] China news according to India media reported by The Hindu, (Periyar University) Pelosi rial University College of Physical Science in the days before hosting the 2015 international light years celebration emphasizes to improve global light based technology is how to promote the sustainable development and the importance of providing solutions for consciousness energy, education, agriculture and health. The challenge.

Das, a professor of inorganic chemistry at the University of science and technology of India, Puspendu, said at the meeting that sunlight, LED and laser would be three of the most important sources of influence in human life in the twenty-first Century.

In recent years, solar photovoltaic technology is mainly used to convert sunlight into electricity through a variety of semiconductors. With the depletion of oil resources, solar energy has become the only clean energy to meet the needs of future generations.

At the moment, LED is not only a variety of applications to illuminate the world, LED is also used to make smart phones, computers and television high resolution display. LED lights are rapidly replacing fluorescent tubes, and even high-definition LCD screen also uses a white LED.

Professor Das pointed out that shortly after the invention of laser technology in the 1960, it led to a revolution in the development of several new scientific and engineering branches.

Progress has been made in the fields of laser technology, nonlinear optics, holography, precision cutting, welding, drilling, laser guided defense equipment, optical communications and laser based surgical instruments.

Through optical communication, laser makes the world very small. If there is no laser, Raman spectroscopy (Ramanspectroscopy) will become obsolete. (compile: China LED network / Nicole)
