2014 the Nobel Prize in physics awarded to scientists in Japan Akasaki Yong, Amano Hiroshi, domestication and for Mura Shuji American Japanese scientists, honoring their respective in the blue light emitting diode outstanding contribution in the process of the invention. Past light-emitting diode (LED) has red and green, but wait until after the 1990s Blu ray technology breakthrough, can be synthesized as close to the solar white light before then trigger a current brought by this wave of LED lighting revolution. The Nobel Prize Committee in winning note, with particular reference to the LED lamp of the invention, for global 15 billion has not been connected to the power network of people, under a bright dream; because the power LED light little by simple solar energy in power would have been enough.
There are still 35% of the world's population is not stable into the power network
The world has a population of 7 billion, 1 billion 500 million not even on the power network, in addition to more than 10 million power network is not stable, and some only a few hours a day. This group of people we call the Poverty Energy, mostly in Africa, Southeast Asia and India.
Without electricity, they must rely on daytime work, engaged in housework, water, and reading, one to the evening, home must rely on candles or kerosene to cook dinner, or engaged in manual.
Use kerosene lamps and candles to read? Not only is too luxurious, the eyes will soon be fatigue, the room will be filled with fuel combustion exhaust, the long-term health of their families will inevitably cause adverse effects. Neither the light reading, let alone watching TV to absorb information at home and abroad, the use of computer Internet is a fond dream. In a new era of globalization and information, the most vulnerable people in these developing countries have been left behind in their education.
Energy poor, there is no reason why power network, mostly located in remote, or "illegally" that unable to get the basic power of the public facilities. He may live in Tanzania partial village, Mumbai will also be able to live in India many slum area in. While LED can reverse this situation.
LED portable charging lamp for the benefit of the masses
India's largest women's groups "All India women's" (All India Women 's Conference) to community as a base to set up community solar charging station for portable LED lamp to charge during the day, people came home from work when you take the opportunity to hire lamp to provide home several days night lighting. Due to solar panels cost to build is still considered is a threshold, so common cooperatives or community through the way of raising funds, will have a chance to can build common charging station; and let the people hire lantern, equal to power cheap "retail" to people in need, making more people can be achieved. Community women are trained as a maintenance technician, to earn a pay plan.
Not only all India women's Federation, and barefoot (Barefoot College), the school with many independent operation of cooperatives, also in the promotion of similar things. Solar light is the reason why in India's much promotion is due to India's leading environmental thinktank Teri to promote long-term illuminate million project, successfully attracted the British government foreign donations to inject. Of course, the solar panel prices fell, and the emergence of LED lamps, the main reason is to let the people enjoy the bright.
With the integration of solar Sandoval
On the other hand, the existing industry developed small solar module collocation LED lamps, specifically the lack of illumination area sales in africa. This group is SunKing Pro the first generation of products, photoelectric plate is small, but fully charged can supply 20 hours of lighting, the second generation of products has reached 36 hours lighting. Incidentally, this set of equipment can also supply mobile phone charging, in recent years, Africa's mobile phone penetration rate is rapidly increased, people using a mobile phone Internet can communicate with the world, the power consumption is less than the computer more.
Find a special business model of Thailand SunSawang social enterprise. The Thai government early in 2004 and helped more than 20 million households without power suburban households to install solar systems. However, there is no maintenance plan, that is as high as 90% of the equipment can not be used again, residents were forced to go back using the candles and oil lamps. SunSawang poineering initial stage, mainly is the maintenance of this was awarded the government abandoned the solar equipment, they try to train community solar power technicians, then later gradually developed different service items, such as a one-year both equipment maintenance, rent solar LED lights, or installing new equipment of domestic solar energy to support small basic appliances.
In the Philippines, a liter of light "(a liter of light) plans you may have on the network read, it is will empty bottles add bleach, installation on the tin roof, the introduction of dim light of day indoor, so also known as" the sun bottles "(solar bottle), construction intensive slum community bring helpful and help the global hundreds of thousands of households. 2013 onwards, team plans to combined solar panels solar PET bottle, inside with LED lights, together with the installation on the roof and in the daytime the introduction of natural light, at night can provide hours of artificial lighting.
Solar LED lights emitted from the light, in the eyes of our opinion maybe small, but it has encouraged community development energy independence, created in green collar jobs and business opportunities, and make millions, tens of millions of people to be reading at night, or is woven, hand, and subsidize home and a step closer to they sought a better life.
