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 lights some simple solutions to a fault, solar street lights flicker, the brightness is unstable. Solution: The primary exchange lamps, if found still the case, checking lines. Second, the solar-powered street lights in rainy days shorter. Solution: First, check the record to see if a daily charge to ensure 5-7 hours of charging Pingxiang 25w solar street every day, if the charge is no problem, then check the battery is not aging. Third, solar street lights stopped working. Solution: first check whether the controller in question (which is the majority). Fourth, the solar panels so as not to be blocked in order to avoid the influence of light. To promptly clean up the dust on the top so as not to affect the charging.

Solar lighting products are green, safe, energy-saving features. Solar street lights are low-pressure or high-pressure die first, at the same output power, high-voltage LED drive current is much lower than the required low-voltage LED. As with Epistar high pressure blue 1WLED for example, the forward voltage drop of up to 50V, but also that it is only 20mA drive current can be 1W output power, while the average forward voltage drop of 3V 1WLED, need 350mA driving current to 1W output power, so the same power output high voltage LED power dissipation during operation is much lower than the low-voltage LED, which means cooling aluminum housing costs can be greatly reduced. Second, the high pressure can significantly reduce LED AC-DC conversion efficiency losses. To 10W output power, for example, if the forward voltage drop of 1W high voltage LED, the output of 50V can take 2 and 4 string configurations, four series LED forward voltage drop of 200V, that is to say just from the city 220V AC power (AC) 20V use bridge rectifier and drop it. But if we adopt a forward voltage drop of 1W Low Voltage LED 3V, even strung together 10 forward voltage drop, but also 30V, that is to say the buck from 220VAC mains need to 30VDC. We know that the lower the input and output differentials, AC to DC conversion efficiency is higher, such as high-pressure visible LED, transformer efficiency can be greatly improved, thereby significantly reducing the power loss of AC-DC conversion Pingxiang 25w solar lights, reduce the heat consumption can be further reduced cooling housing costs.

How to check the quality of construction of solar street light solar street quality management team, headed by a high level of technology, good quality, experienced technical workers, the construction of the installation process, do a good job quality inspection work; ready to start before the construction team work, including familiarity with procedures, specifications, construction drawings, construction plans and technical requirements. Solar street dig digging buried box size: pedestal adjacent dots and garden lights, solar street lights 25w Pingxiang deep 700MM, length 600MM, width 550MM. Buried box pool is surrounded by single brick masonry cement, the installed battery box into the buried tanks, lead pipes, roof cement board Pingxiang 25w solar lights, battery positive electrode, a negative electrode, respectively, and the power supply controller positive, negative corresponding connections are secure. Then spread a layer of Vaseline joints. LED light source; and a controller is generally placed in the pole, with light control, time control, overcharge and over discharge protection and reverse polarity protection, more advanced lighting controllers more time with seasonal adjustment function, half-power, intelligent charge and discharge function; battery is generally placed in the ground or the battery will have a special incubator, it can be VRLA batteries, gel batteries, lithium batteries and other Fe-Al batteries or purchase solar lights, solar street lights working Xinyu, Pingxiang solar street by the Nanchang Ou Optoelectronics Technology Limited. Nanchang Ou Optoelectronics Technology Co., Ltd. (www.okled.cn) is in Nanchang, Jiangxi, a leader in solar and renewable energy, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Optical leadership in Europe can with the staff warmly welcome all inquiries negotiations to create a better Europe can photoelectric future.
