With the increasing use of solar street lights, we will see solar street lights from time to time when we walk on the road. Especially in some villages and towns, this kind of energy saving and environmental protection, and the subsequent use of the cost is small, is an important part of the urbanization of road lighting construction. However, as for the principle of solar street light system, it is estimated that many people still have a little understanding. Next, Century Sunshine will tell you the working principle of solar street light system.
All solar street light systems adopt centralized control technology and have overcharge and overdischarge protection devices. Corridors and corridors use a set of lighting systems for each building; roads, courtyards, areas, and lawns also use multiple large-scale lamps to share a set of solar photoelectric conversion, storage and control systems according to local conditions. The lamps range from a few to dozens of poles. The power of solar panels ranges from one hundred watts to several kilowatts. Its advantages are reasonable design and configuration, saving solar panels; convenient for setting or resetting in analog digital control; conducive to the use of new technologies such as external power supply automatic switching charging, battery panels automatically tracking the sun, etc.; because of its strong adaptability, it is not restricted by lighting conditions, and it can also be used under the shade of trees, beside corridors, basements and tunnels.; the cost of lamps and foundations can be reduced without considering the influence of wind and snow on the light poles; the centralized storage of batteries is convenient for maintenance, replacement and use of working conditions.
The battery is a key component of solar lighting. Since the system must have a redundant design, the battery capacity of the solar street lamp system is relatively large, which affects its work activity and causes the effective capacity to gradually decrease. In the system, the battery capacity is selected flexibly, intelligently combined, and overcharge, overdischarge and anti-recharge protection settings are carried out, which can double the effective capacity time of the battery. This technology is used in large street lamp systems and large landscape lighting. The application effect in the system is particularly obvious.
The solar LED automatic lighting control system adopts photosensitive elements to detect the light intensity in the evening, inputs analog signals to the control system, and is processed by digital circuits to automatically turn on the lighting circuit when the darkness is appropriate, and intelligently handle some transients Dim lighting that is not night.
Through the points mentioned by Century Sunshine, we can understand the working principle of the solar street light system more clearly, and better understand the product quality of street light manufacturers when we buy solar street lights.
