Solar LED lighting lit a small village in Chongming

　　Last year , the village with the Shanghai Academy of military benefits in educational practice in the mass line " get to know " the researchers began field research , design lighting solutions. Dean Niu Xiaoming found newly installed street lights in the village is best not to pull cable , to open automatic switch off , and from routine maintenance. So , they use LED lighting in the form of green solar energy for rural applicability to research and development. Even the appearance of several lights also " publicity" for the villagers to choose from.

　　The first test installed eight , dark is bright , lighting time is set to 8 hours , continued until about 1:00 . Unexpectedly, the villagers' opinions came - the original , the villagers every day to bring your own ground kind of thing , catch an early ride to the town market , usually three or four in the morning we should go out. Accordingly , researchers and forth several times, re-adjust the " rural model" , will illuminate the length of time 2.5 hours ; Meanwhile , in order to take into account the following day endurance street lights , night lighting at full power before 10:00 , after 10 pm will be replaced and a half power lighting.

　　Currently , the village every 35 meters on the road home a newly installed street lights, covering 4.4 km Village Lane . Even 3-7 days of continuous rain , but also to ensure the normal lighting. Photonics Research Institute , deputy director of the research center Yin Chun -rong , this system, with the photoelectric conversion , by a 12-volt or 24 -volt DC power supply , not even the power grid and without electricity, street light leakage will not hurt the livestock events. He said the "country version of" street project can be copied , can be extended , " 25-year solar cells available , LED light source can be used for 15 years for electricity storage battery can also be 3.5 years to 4.5 years ."
