1. Working principle of solar bollard garden lights

The working principle of the system is simple. The solar cell made by the principle of photovoltaic effect receives solar radiation energy in the daytime and converts it into electrical energy output. It is stored in the battery through the charge-discharge controller. When the illuminance gradually reduces to a certain degree at night, the charge-discharge controller detects that the voltage is lower than the set value and acts. The battery discharges the lamp head and starts lighting. When the battery is discharged to the set time, the charge and discharge controller acts to cut off the power supply circuit of the street lamp, so that the discharge of the battery is completed.

2. Advantages of solar bollard garden lights

(1) Energy-saving: provide electric energy with solar photovoltaic conversion, inexhaustible and inexhaustible;

(2) Environmental protection: no pollution, noise, and radiation;

(3) Safety: no electric shock, fire, and other accidents;

(4) Convenient: simple installation, no need for stringing or "rifling" digging construction, no concern about power cut and power limitation;

(5) Long life: high technology content, control system, intelligent design, reliable quality;

(6) Less investment: one-time investment is equivalent to alternating current (alternating current investment starts from transformation, power supply, control box, cable, and project), one-time investment and long-term utilization;

(7) Wide application: solar energy comes from nature, so it can be used wherever there is sunshine. It is especially suitable for green landscape lighting, high-grade residential and outdoor lighting, coastal landscape lighting and embellishment of tourist attractions, street lighting of Industrial Development Zone, industrial and mining enterprises, and outdoor lighting of colleges and universities.

3. Comparison with traditional street lamps

The overall design considers all aspects; the peak wattage selection design and battery capacity selection design of photovoltaic modules adopt the most common design method at present, and the design idea is relatively scientific; the wind resistance design is analyzed from the two parts of battery module bracket and lamp pole, and the analysis ratio is more comprehensive; the surface treatment adopts the most advanced technology at present; the overall structure of street lamp is simple and beautiful; after The actual operation shows that the matching between each link is good.
