Nanchang Ou Optoelectronics Technology Co., Ltd. The main products are: solar lights, solar garden lights, solar lawn lights, solar wind and solar street light series; a variety of LED light sources, solar PV modules, batteries, controller; various lampposts, garden poles, waterproof case and supporting the use of flip-flops, light control when the control switch and other electrical products. Solar lighting products are green, safe, energy-saving features. Solar power system installation problems with the installation of a grid-type solar power generation equipment, has become a popular home roof, solar power freest users. But understand installation costs, we can only hope that step. In the long term, and net domestic solar power system can really help users save electricity costs, but needs to be placed a large initial installation cost of lawn and costs far beyond the expectations of users, many customers are waiting. Solar photovoltaic power generation can effectively save electricity costs, which is not in doubt. If the implementation is feasible 3w lawn can be used to minimize installation costs? This is the ability to design as much as possible we can do to keep the sun Yingli New Energy Co., status quo analysis. A basic fact is that if the average current price of 0.4 yuan per kWh in solar photovoltaic power generation investment money is impossible, because the current average consumption of electricity is $ 1 per 0.6 degrees left and right sides. Family common grid system is self-occupied, Yu Electrical access to the Internet. Yes, the first is to meet their needs, their inexhaustible power, to buy back the public grid. It can give a home power supply time only during the day, at night you must use the electricity grid. Nanchang Ou Optoelectronics Technology Co., Ltd.

Solar lighting products are green, safe, energy-saving features. Battery performance solar street lighting large current discharge performance: NP series battery plate, positive plate thickness of 2.4 - between -2.9 mm, high porosity formula of the active substance dish large specific surface area, which is suitable for high current discharge. Solar street life: Because NP Series battery sheet, positive grid corrosion resistance is relatively poor, relatively short battery life, when the ambient temperature of 25 plus or minus 5 degrees Celsius, 5--8. Sealing reaction efficiency solar street: NP series battery plates thin, drawing number, surface area, easily sealed reaction. And the battery compartment is small, generally sealed reaction efficiency is higher than 98%. Nanchang Ou Optoelectronics Technology Co., Ltd.

Solar lighting products are green, safe, energy-saving features solar street lamp Why use constant current source 1, the characteristics of LED lighting material determines its influenced by the environment, such as elevated temperature, LED current will increase voltage increase in LED current will increase. Long-term than the rated current, will greatly shorten the LED lamp beads life. The LED constant is change when environmental factors such as temperature and voltage, ensure its current value remains unchanged. 2, solar street lighting power supply current precision: current precision on the market power of some poor, as the popularity of the recommended programs constant program error of ± 8%, constant error is too large. ± 3% generally require it. 3% of the design. To fine-tune the production of power in order to achieve ± 3% error. 3, the voltage of the solar lamp power supply: LED general recommended voltage is 3.0-3.5V, has been tested, mostly in 3.2V lawn lamp 32w, so according to 3.2V formula quite reasonable. N light bead series total voltage = 3.2 * N. 4, solar street lighting power supply current is how much is the most suitable: for example LED rated current of 350 mA, some plants used to make the design 350 mA, in fact, this current heat very serious Lawn Light net , after repeated comparison test, designed to 320 mA is ideal. 5, series-parallel solar street with wide voltage power supply board to how wide it: For LED solar street lighting power supply input voltage range is wide range AC85-265V, then the LED lamp series-parallel plate is important.
