LED lighting and solar integration into the new darling

LED lighting and solar integration into the new darling

The Nobel Prize for Physics in 2014 was awarded to Japanese scientist Akira Akira and Amano Amano, and Japanese-American scientist Nakamura Nakamura, who was a native of the United States, for their outstanding contributions to the invention of blue light-emitting diodes. In the past, light-emitting diodes (LEDs) have been red and green, but to wait until the 1990s Blu-ray technology breakthrough, can be synthesized for the white light close to sunlight, and then triggered the current wave of LED lighting revolution. Nobel Committee in the award-winning note, with particular reference to the invention of LED lights, the world's 1.5 billion people can not even connected to the power network, make a bright dream; because LED lighting power required by Simple solar energy on the ground will be sufficient.
There are still 35% of the world's population is not stable into the power grid
There are 7 billion people in the world, 1.5 billion is not connected to the power network, there are more than 1 billion more unstable power network, and some can only provide power for a few hours a day. We call this group Energy Poverty, mostly in Africa, Southeast Asia and India.
Without electricity, they had to rely on daytime work, watering, and reading. In the evening, the family had to rely on candles or kerosene to cook dinner, or to work at home. With kerosene lamps and candles to read? Not only too extravagant, the eyes will soon fatigue, indoor combustion fuel will be diffuse after the exhaust gas, long-term health of the family inevitably adversely affected. Neither light reading, let alone watching TV to absorb domestic and foreign information, the use of computer Internet is wishful thinking. In a new era of globalization and informatization, the education of the most disadvantaged groups in these developing countries has been left far behind.
The energy poor have no electricity network, mostly in remote, or "illegally," homes that are incapable of access to basic public utilities. He may reside in rural Tanzania, or live in the slums of the Mumbai metropolitan area. However, LED can reverse this situation.
Portable LED rechargeable light for the benefit of the masses
India's largest women's group, the All India Women's Conference, set up community-based solar charging stations to recharge portable LED light bulbs during the day. People rushed home from work to rent electric lights to provide homes Day and night lighting. Since the cost of building solar panels is still a threshold, there is an opportunity to build a common charging station through joint co-operatives or community-based fund raising, while letting people rent lanterns is to "retail" electricity cheaply to those in need , So that more people can get. Women in the community are trained as equipment maintenance technicians to plan for remuneration.
Not only the All India Women's Federation, but also Barefoot College, and many independently operated cooperatives, are pushing for similar things. The popularity of solar lighting in India is due to India's well-known environmental think tank TERI long-term promotion of "bright millions of people" program, successfully attracted the British government and other foreign donations. Of course, the price of solar panels fell, and the emergence of LED lamps, is the main reason for everyone to enjoy the light.
In this case,
LED and solar integration into the new darling
On the other hand, the industry has invented a small solar module with LED lamps, specifically in Africa and other regions of the lack of lighting sales. On the map This group is the first generation of SunKing Pro products, photovoltaic panels, though small, but full charge can supply 20 hours of lighting, the second generation of products has reached 36 hours of lighting. Incidentally, this group of devices can also supply mobile phone charging, mobile phone penetration rate in Africa is rapidly increasing in recent years, the public can use the Internet to communicate with the world, the power consumption is much less than the computer.
SunSawang social enterprises in Thailand find a special business model. As early as 2004, the Thai government helped more than 200,000 rural households with no electricity to install solar energy systems. However, there was no maintenance program so that up to 90% of the equipment could not be used and residents were forced to go back to using candles and oil lamps. SunSawang started out with solar energy equipment that was abandoned by the government. They tried to train the solar power technician in the community, and then gradually developed different service items, such as one-year maintenance of existing equipment, rental of solar energy LED lights, or the installation of new home solar equipment to support small basic home appliances.
The "A Liter of Light" program in the Philippines Perhaps you have seen it on the web by adding bleach to an empty Bottle and installing it on a tin roof to introduce daylight into the dark interior. Also known as the "Solar Bottle" (Solar Bottle), for the building-intensive slum communities to bring great help, and to help hundreds of thousands of families around the world. In 2013, the team began to promote the combination of solar panels with the sun Bottle, which together with LED lights, installed on the roof, in the daytime the introduction of natural light, at night can provide hours of artificial lighting.
In this case,
Solar photovoltaic technology and LED lighting can be the perfect combination of the key to both with the DC, the voltage is low and can match each other. Therefore, the combination of the two does not need to be generated by the solar cell DC into AC, thus greatly improving the efficiency of the lighting system to achieve energy saving, environmental protection, safe and efficient lighting system, can be described as a near-perfect combination.
The bright light emitted by solar LED lights has stimulated the community to develop its own energy sources, created green-collar employment and business opportunities, and let millions and tens of millions of people read at night, or weaving and hand-making, , And then step by step closer to what they seek a better life
