Yufai: Principle of Solar powered street lamp system

With the increasing use of Solar powered street lamps, we will see Solar powered street lamps 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. But as for their working principles, it is estimated that many people still have little understanding. Let me explain the principles of the Solar-powered street lamp system for you below.

1. Multi-pole lights share a set of solar photovoltaic system

All solar lighting fixtures adopt centralized power supply, 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; easy to set or reset in analog and digital control; facilitate the use of new technologies such as external power supply automatic switching charging, battery panels automatically tracking the sun, etc.;

2. Battery working status control

The battery is a key component of solar lighting. Since the system must have a redundant design, the capacity of the storage battery 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, over discharge, and anti-recharge protection settings are performed, 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

3. Analog and digital hybrid control technology

The solar automatic lighting control system uses photosensitive elements to detect the light intensity in the evening, and inputs analog signals to the control system. After digital circuit processing, the lighting circuit is automatically turned on when darkness is appropriate, and some short-circuit non-dark night dark lights are processed intelligently.

Through the points that Yuhui told you, we can have a clearer understanding of the working principle of the solar LED street lamp system. When we buy Solar powered street lamps, we can better understand the product quality of street lamp manufacturers.
