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. LED solar street light will be a reliable system voltage peripheral circuits are mostly solar lights 12V or 24V LED light source we used the majority, town garden lights, which touched me deeply, in a few years time we assembled three generations of LED light source, real saw it from dark to light, European garden lights, the light fades serious to the light attenuation small course, LED light failure certainly has its physical properties, but the selection of better quality Great power LED lamp beads, while making constant current regulation of LED dedicated control circuit, courtyard lamp, to be adopted by the current sub-time control to achieve better energy-saving purposes, the battery pack can be used to reduce power at the same time the higher the stability of the system.

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, Gian courtyard, 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 AC-DC conversion, which a reduction of heat consumption can be further reduced cooling housing costs.

Solar lighting products are green, safe, energy-saving features. The client must pay attention to three aspects of the installation of solar street lights First, the absorption of solar radiation in itself because it is a form of solar energy lights solar radiation energy absorbed by the lighting equipment, mainly energy, therefore when people use solar lights, must be its energy absorption problems have been concerned. In many cases, consumers do not know how to ensure due metropolitan energy supply solar lights, and wrong to make solar panels absorb solar lights on can not face the sunlight, or by some of the more high tree-lined blocking the absorption of energy . Secondly, if the tightness of solar street lights in the use of solar energy has not be sealed route, so it will cause unexpected damage occurs in the course of street lighting facilities, for those who want long-term guaranteed use of solar street lighting state party is concerned, once such conditions, so the line will issue its solar lights bring very serious impact. Finally, the control system stability in the various factors to improve, consumers also need to focus on the stability of the control system of solar street lights, street itself because it is extremely stable and the ability to use stress, revealing when should the stability of the system because many controllers can not use sufficient effect, so will bring another round of impact on the use of lights, so in the case of such need their own installation, we must provide its stability control system.
