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. Series-parallel with the wide voltage power supply board LED lights to be more wide? For LED solar lights work in a relatively wide range of input voltage range AC 85-265 V, the LED lamp series-parallel plate is important. Try not to use a wide voltage, can be divided into AC 220 V, AC 110 V as classification, so as to ensure power supply reliability. Due to the current supply is generally a non-isolated step-down constant current power supply, requiring voltage 110V, the output voltage should not exceed 70 V, serial number no more than 23 strings. Output voltage input voltage of 220 V can reach 156V. That is, the serial number no more than 45 strings. Parallel Number not too much, otherwise too much current work, power serious fever.

Principle of solar battery solar battery types, valve-regulated lead-acid batteries, VRLA batteries, maintenance-free lead-acid batteries VRLA batteries, maintenance-free sealed lead-acid batteries, led solar lampposts, lead-acid batteries, lead Principle acid batteries, lead-acid battery prices, lead-acid battery charging method, lead-acid battery repair lead-acid battery works solar energy batteries, maintenance-free valve-regulated lead-acid batteries Introduction: solar batteries, also known as maintenance-free valve-regulated lead-acid batteries, is dedicated to the development and production of solar power systems, high-quality solar lights, has the following advantages: 1) safety performance is good: no electrolyte leakage under normal use, no cell expansion and rupture. Good 2) discharge performance: stable discharge voltage, discharge platform gently. 3) good resistance to shock: fully charged battery completely fixed to 4mm amplitude and frequency of vibration 16.7HZ one hour, no leakage, no cell expansion and cracking, open circuit voltage is normal. 4) impact resistance: the battery is fully charged state 20CM height from the natural fall to the 1CM thick hardwood board 3 times no leakage, no cell expansion and cracking, open circuit voltage is normal.

Solar lighting products are green, safe, energy-saving features. Solar street light maintenance issues usually pay attention to 1, usually clean up with a clean feather duster to gently dusted, led solar lamp head, to be very careful. 2, if it is non-metallic sun light can wipe clean with a damp cloth, taking care not to rub the power cord. 3. If the lighting metal can with a dry cloth, do not wet. Note that after the appearance of the installation of solar street light pole. Starting from the basic construction, lamp position to control the main subject linearity, Ganzhou solar lights, and reasonably linear change according to road design, straight poles, machining and welding manhole to avoid the main line direction, and across the board to maintain agreement.
