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. Factors affecting solar street life What are the main elements are: 1, lighting: light is not the same life expectancy is not the same, you can choose the low-pressure sodium lamp light source, low voltage lamp, LED lights, fluorescent lamps and other low pressure. Today, the use of sodium and LED lights more. Sodium cheaper prices. Life expectancy is shorter. LED lights now at 50,000 hours of good quality, in theory, 10 hours a day, you can use 10 years. So the first selection of a good light. 2, light source launch control: not the same launch method is not the same, not the same demand for ballast or drive power lights. This large part on the light source. Especially the LED light source. Now generally use constant current source driver. The quality and size of the current source setting parameters can suitable light source is very important. Mainly to see: precision constant current, output power, protection circuit, parameter setting scale. 3, Solar Controller: Solar street light system not only controls, monitoring, maintenance of the photovoltaic module, batteries, operating status of the load. Together useful in handling the battery of the job situation, but also directly maintain the load (solar lights), to which is supplied a useful and relatively stable operating environment, in particular the lack of battery power, or in critical condition under voltage operations and other operations. A high precision, stable solar controller functions will play a key role. Nanchang Ou Optoelectronics Technology Co., Ltd.

Solar lighting products are green, safe, energy-saving features. Solar road light pole installation time probably pay attention to what? 1: means the point lampposts probably practice of combining traffic road to the resolution, which would not they want to secure safety which, it is necessary to ensure lampposts practicality, but also to ensure that the public security, but also to ensure that the city is beautiful, and therefore still needs very seriously. 2: Bayonet lampposts cantilever rod to the interval between the lowest floor of not less than 5.5 meters, which is measured out by expert severe, and must not violate, or low passage of many vehicles will be constrained, and high imaging possible point of view is not so good, the camera can not reach the desired effect. 3: Lampposts everything necessary to fully welded welding Weld appearance may not exist, but it is necessary to meet the strong light poles, due to its year-round outdoor, to have suffered a variety of adverse weather, and still ensure a straight posture. So strong is very important. 4: It's just in the construction of local demand attention, the practice in our lives due to the character played by contrast lampposts important, buy garden lights, and its functional requirements and high contrast, so we often also high, Just so, ability to ensure the safety of citizens, ensure the safety of the whole society.

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, courtyard, 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, garden lights factory, that need to step-down from 220VAC mains to 30VDC. We know that the town garden lights, 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 AC-DC conversion of power loss, reduce the heat consumption can be further reduced cooling housing costs.
