Solar LED lighting works in Chongming

Alternate winter and spring, every day at 5 am, the town of Hong Kong, Chongming, along the town of Hui village, the new light of the new street lights automatically turn up, here has become the only bright village along the river". About the village residents passing, envy, because most of the rural Chongming Island also no street lights, let alone into the Village Lane home road lighting. The Spring Festival, in the Hui village more than 1 thousand and 800 villagers from dawn to dusk, go home, no longer rely on the moon and flashlight.

Hui in the village south of the river, the river in 2007 when the main road was laid on a street, a total of 68 light. But the way the depth direction of home, is the twenty or thirty "alley, nearly 800 households still couldn't excuse me, one of the most deep alley about 400 meters, to in the evening darkness. Village Party Secretary Qiu Yongkui told reporters, because most of the young people in the village to work outside the home for the elderly and children, travel at night is not convenient and safe.

Last year, Hui village and the Shanghai Academy of Sciences in the mass line of educational practice to get to know, researchers began field research, design lighting solutions. Dean Niu Xiaoming found that the village is not the best new street lamp cable, to open the switch off automatically, and from routine maintenance. As a result, they use a green energy-saving solar LED lighting form, for the suitability of rural development. Even the appearance of the street is also a "publicity" for the villagers to choose.

Initially tried to install 8, dark is bright, lighting time is set to 8 hours, lasting until around 1 in the morning. Unexpectedly, the views of the villagers, the villagers to the original, a day in which to bring their own things, riding a bike to town to catch the morning, usually at three or four in the morning to go out. Accordingly, the researchers back and forth several times, re adjust the "rural" mode, the lighting time prolonged 2.5 hours; at the same time, in order to take into account the next street life, late before 10 full power lighting, after 10 nights instead of half power lighting.

Currently, the village home every 35 meters on a new street lights, covering the village of 4.4 km lane. Even continuous rain 3 to 7 days, but also to ensure normal lighting. On the Institute of optoelectronic research center deputy director Yin Chunrong introduced this system with photoelectric conversion by 12 or 24 volt DC power supply, not even the power grid without electricity, without injuring people or animal Street leakage event. He said that the country version of street lamp works can be copied, can be extended, solar cells available for 25 years, LED light source can be used for 15 years, for storage battery can also be used for 3.5 to 4.5 years. "

For the sake of this good thing, the villagers also took the initiative to help the construction personnel, in the light of embedded battery, "i s no other, dig a hole no problem". Battery fully sealed, no pollution, 35 years after the replacement can be recycled. The researchers also taught the village electrician to complete the basic operation, such as the use of infrared remote control and direct "dialogue" on the street after the sunshine change according to the season, and then set some parameters. Village spring, night long, also to the village surrounding the village of stopping at the light".
