Long Vietnam Anhui Environmental Engineering Limited was established in June 18, 2012, the registered capital of 53.5 million yuan. The company mainly produces "lithium and lithium intelligent solar street light off-grid energy storage system" series of products, the product from the Hai Lang V Green Technology Co., Ltd. jointly Shanghai University first-class research team, after several years of research and development process, the first in the country to Lithium first intelligent solar street lamp has a "long life, environmental pollution, energy saving, low carbon, cost-effective" in the true sense of success in 2011 in Shanghai lit. Build a scientific "Three Three One Environmental" to lithium intelligent storage control system as the core of the perfect combination. That compared with lead-acid gel batteries with the power of solar street: about one-third the weight of a volume of about one-third of life is more than three times, environmental pollution. Long the "lithium intelligent solar street light," is currently the only argument CQC through national solar photovoltaic testing center. Long the "lithium intelligent solar street light that is off-grid power lithium energy storage system," scientific and technological achievements in the September 17, 2014 in Beijing successfully passed the national identification, the former Secretary-General, Comrade · Advanced Science and Technology deputy director of the evaluation committee and technological achievements; National Standards Administration has prepared the National Conformity Assessment CNAS 17025 testing laboratory built in Long Vietnam; Lang also passed the European CE safety certification and the EU ROHS certification. Long more intelligent lithium storage control system through the Shanghai Institute of Technology Department of Information Technology domestic novelty, the conclusion is: no domestic same intelligent storage control system, which has a novelty in the country; international technical novelty concluded: Long the lithium battery Intelligent storage control system is innovative, meet international standards. And has been a national intellectual property patents for inventions declaration accepting that an intelligent lithium solar street lighting system, a scalable method for controlling the rotation matrix display, a solar LED lights, a boost constant current power supply output short circuit protection circuits, based on measuring human traffic lights system, an intelligent control system, energy saving lamps A lithium hypothermia protective packaging A Boost LED Driver short-circuit protection, bipolar switching power conversion circuit, based on double PWM voltage conversion charge and discharge control circuit, a battery protection system and method for balancing, new energy saving street lighting device, a battery pack protection system balanced. Long the lithium intelligent solar energy-saving lamps, which take full advantage of natural light and scenery resources resources, no consumption of mains electricity; environmental use of solar, wind pollution. Unlike lead-acid gel batteries, lithium is a controllable, non-polluting energy storage battery; the effective life of long-life solar PV panels is more than 10 years, the effective life of the LED light source 40000-50000 hours. 8-10 years of useful life of lithium batteries, can be a perfect match with the system; economical intelligent system LED light source, photovoltaic modules, lithium batteries for a reasonable match to reduce the energy loss caused due to matching unreasonable; intelligent decisions based on user needs, remaining battery capacity, day and night long, intelligent optimization weather conditions, a reasonable allocation of power levels and achieve light control and time control, in order to ensure continuous rainy days 7-15 every night filled night lights . Long the people intended to comply with the development trend of the country, namely, the development strategy should always be followed by the national strategy; Lang Always the product development to meet market demand; Long the cause must be meaningful, that the country, and sustainable development. To revitalize the national economy, promote healthy social development, promote social groups for the purpose of common progress, and strive to achieve industry groups, standardized management, technical innovation, marketing three-dimensional, patterns humane. Long the light in front, fame career at home and abroad is willing to share insight! Long more "intelligent solar street light lithium" long life, environmental pollution, energy saving, low carbon, for livable homes, is the ideal choice for current and future urban roads and better rural lighting!
