Due to the large area and poor light of the underground parking lot, a large number of lighting equipment are required for long-term lighting. If common control method is used, the route required is long and the circuit is complex, and it is difficult to realize the automatic control of the internal lighting of the parking lot with a simple strong current control mode because there is not a simple one-to-one correspondence between each exit and the driving route. And usually only the continuous lighting mode can be used. Therefore, most of them are realized by solar power lighting system and solar light for parking lot.
The system uses solar cell modules to convert the collected solar energy into electric energy, which is converted and distributed through the solar controller. On the one hand, the electric energy is directly provided to the corresponding lighting equipment and other loads, on the other hand, the excess electric energy is stored in the battery through the solar power storage systems as night lighting, emergency lighting or are used for standby when the power generated by solar cells is insufficient.
The solar lighting system adopts the sensor lighting mode for different times and environments, and carries out accurate setting and humanized management for the illuminance. Only when a car or person is sensed to enter, the light can be lit or adjusted to the required brightness, and the minimum energy can be used to ensure the required illuminance level. The system power supply is equipped with the power supply protection device of municipal power network, so that the load work is completely free from the influence of cloudy and rainy weather.
Good stability:
Solar power lighting system is powered by solar power, battery and municipal power supplementary protection device, which work together, so as to ensure the stable and normal operation of the system all day, almost free from the influence of weather;
High safety:
The solar power lighting system adopts the principle of separation of strong and weak electricity. The power generation part belongs to strong electricity and the power consumption part belongs to weak electricity. In case of human misoperation, there is no problem of electric shock injury;
High degree of intelligence:
The whole system adopts intelligent control mode, and the lights are automatically lit through networked sensor and precise numerical control technology without human operation;
High energy utilization rate:
The electric energy generated by solar energy directly supplies power to the load and stores the battery to avoid photovoltaic energy loss caused by "inversion". The solar power lighting system adopts MPPT (maximum power point tracking) technology, so as to optimize the use efficiency of energy and maximize the utilization of photovoltaic energy source;
Energy saving management:
When no one or vehicle passes through, the system automatically turns off the lamps, reducing energy consumption;
Convenient maintenance and low cost:
The solar power lighting system adopts low-voltage DC, which is safe and convenient for maintenance. The photovoltaic system only needs periodic inspection and little maintenance workload.
