LED needs very little electricity and only simple solar power generation

The Nobel Prize in Physics in 2014 was awarded to Japanese scientists akazaki, Amano Hiroshi, and Nakamura, a Japanese-American scientist, in recognition of their respective contributions to the invention of the blue-light emitting diode. Past light emitting diodes (LED) Red light and green light already exist, but it will not be synthesized into white light close to sunlight until the blue light technology breaks through in the 1990 s, and then the lighting revolution brought about by the current wave of LED will be triggered. The Nobel Prize committee specifically mentioned the invention of LED lights in the award-winning instructions, which will make a bright dream for 1. 5 billion people who cannot connect to the power network; Because the power required to light the LED is very small, it is enough to generate electricity on the ground by simple solar energy. There are still 35 people who have not been stably integrated into the power grid. There are 7 billion people, 1. 5 billion of whom are not connected to the power network. In addition, there are more than 1 billion unstable power networks, some of which can only supply power for several hours a day. This group of people we call the energy poor (EnergyPoverty)Most of them are in Africa, Southeast Asia and India. Without electricity, they must rely on daytime work, housework, water intake and reading. At night, their families must rely on candles or kerosene to cook dinner or do family manual work. Reading with kerosene lamps and candles? Not only is it too extravagant, but the eyes will soon be tired, and the room will be filled with the exhaust gas after fuel burning. In the long run, it will inevitably cause adverse effects on the health of the family. There is no light to read, let alone watching TV to absorb domestic and foreign information, and using computers to access the internet is even more wishful thinking. In the new era of globalization and informationization, the education of these vulnerable people in developing countries has been left behind. The reason why the energy poor do not have a power network is that they are mostly remote or illegally inhabited, so that they cannot obtain basic electricity. He may live in a rural settlement in Tanzania, or he may live in many slums in the metropolitan area of Mumbai, India. However, LED can reverse this situation. Portable LED rechargeable light benefit the masses India Big of women groups All India Women Association ( AllIndiaWomensConference) Based on the community, the community solar charging station is set up to charge the portable LED lights during the day. When the people go home from work, they rent the lights and provide a few days of night lighting at home. Since the cost of building solar panels is still a threshold, there is an opportunity to build a shared charging station through joint cooperatives or community fundraising; Letting people rent lanterns is equivalent to retailing electricity to people in need, so that more people can get it. Community women are trained as equipment maintenance technicians to earn salaries. Not only the All Indian Women's Federation, but also barefoot schools (BarefootCollege) In addition, many independent cooperatives are also promoting similar things. The reason why solar lamps are widely promoted in India is that TERI, a well-known environmental think tank in India, has long promoted the plan to illuminate millions of people and successfully attracted foreign donations from the British government. Of course, the sharp drop in the price of solar panels and the emergence of LED lamps are the main reasons for everyone to enjoy the light. Portable small solar power generation and LED lighting group SunKingProLED and solar energy are integrated into a new favorite. On the other hand, some manufacturers have invented small solar modules with LED lamps, which are specially sold in areas lacking lighting such as Africa. The above picture is a SunKingPro generation product. Although the photoelectric board is small, it can supply 20 hours of lighting after being fully charged. The second generation product can already reach 36 hours of lighting. By the way, this set of equipment can also supply mobile phone charging. In recent years, the penetration rate of mobile phones in Africa is rapidly increasing. People can use mobile phones to communicate with the world, and the power consumed is much less than computers. SunSawang social enterprises in Thailand have found a special business model. Thailand government as early as 2004 will help more than 200 thousand user does not have power of suburban family installation solar system however but no maintenance plan that up to nine of equipment can't again ', residents were forced to go back to use candles and oil lamps. In the initial stage of SunSawang's business, it was mainly to repair this batch of solar energy equipments that were abandoned by the government. They tried to train the solar power technicians in the community, and then gradually developed different service projects, for example, one-year maintenance of existing equipment, rental of solar LED lights, or installation of new home solar equipment to support small basic appliances. One liter of light in the Philippines (ALiterofLight) The plan may have been seen on the internet. It is to add bleach to the empty treasure bottle and install it on the iron roof to introduce daytime light into the dark room, so it is also called the Sun treasure bottle (SolarBottle) For building intensive of slums community bring very big of useful and help the number of 100,000 households family. Since 2013, the planning team has begun to promote the solar baote bottle combined with solar panels, which is equipped with LED lights and installed on the roof together, introducing natural light during the day and providing several hours of artificial lighting at night. Residents of a community in the Philippines personally use solar LED lights to make community street lamps. The key to the combination of solar photovoltaic power generation technology and LED lighting is that the two are both direct current, low voltage and can match each other. Therefore, the combination of the two does not need to convert the direct current generated by the solar cell into alternating current, thus greatly improving the efficiency of the whole lighting system and realizing an energy-saving, environment-friendly, safe and efficient lighting system, it can be said that it is a close combination.
