This year\'s Nobel Prize winner was rewarded for inventing a new energy source --
Efficient environmental protection-
Friendly light source-blue light-
LEDs (LED ).
In the spirit of Alfred Nobel, the award rewards an invention of the greatest interest to mankind;
With blue LEDs, white light can be generated in a new way.
With the advent of LED lights, we have more time now
Durable and more efficient alternatives to old light sources.
When akizaki Isamu, Tianye Guangzhi and Nakamura second from half of them
The conductors in early 1990, they triggered
Mind change in lighting technology.
Red and green diodes have been around for a long time, but no white light can be produced without blue light.
Despite considerable efforts by the scientific community and industry, blue LED remains a challenge for 30 years.
Where everyone else failed, they succeeded.
Chiaki worked with Tiano at Nagoya University, where nak worked for Nichia Chemicals, a small company in Dedao.
Their invention was revolutionary.
Incandescent lamps lit in the 20 th century;
The 21 st century will be lit by LED lights.
Bright white LED light, long
Lasting Energyefficient.
They are constantly improving to achieve higher efficiency with higher luminous flux (in lumen) per unit of electrical input power (in watts.
The most recent record is more than 300 lm/W, and ordinary bulbs can be compared to 16, and fluorescent lamps can be compared to nearly 70.
Since the electricity consumption of about 1 out of 4 parts of the world is used for lighting, the led helps to save the Earth\'s resources.
Due to the led duration of up to 100,000 hours, the material consumption is also reduced, compared to 1,000 hours for incandescent lamps and 10,000 hours for fluorescent lamps.
LED lights are very promising to improve the quality of life over 1 year old.
5 billion people around the world are unable to use the grid: cheap local solar power is available due to low demand for electricity.
The invention of the blue LED is only 20 years old, but it has created white light for the benefit of all of us in a completely new way.
