Working principle and composition of solar lamp scheme development

This paper introduces the working principle and composition of a solar lamp scheme development; Through the DC controller, it can ensure that the battery will not be damaged due to overcharge or excessive discharge under the sun or long-term cloudy and rainy weather. It also has the functions of light control, sound control, temperature compensation, lightning protection and reverse polarity protection.

Working principle

The solar lamp uses the volt response principle of solar cells, collects solar photons from solar energy during the day, charges the battery pack through the controller, and supplies power to bulb components at night.

Solar column head lamp

characteristic

1. Independent installation, no line embedding and backfilling, saving construction cost;

2. No need to increase storage capacity, saving the cost of supporting equipment;

3. No power is used to save power operation cost;

4. Simple maintenance and no electric shock;

5. It is very energy-saving and can be directly converted into electric energy through sunlight;

6. The DC voltage used is 12V ~ 36V, which will not cause electric shock or fire;

7. Simple installation, no need to worry about power failure, and can be used where there is no electricity;

8. Long service life, strong light efficiency, energy-saving light source, long-term durability;

9. There is no need to pay electricity, and the operation and maintenance cost is low;

10. Solar lamps are widely used in residential areas, schools, factories, scenic spots and other areas;

11. The replaced solar panels can be recycled; 12. High end, energy saving, is the symbol of taste;

Solar projection lamp

form

1. Solar panel: the function is to convert light energy into electric energy;

2. MCU controller: it is the core part of the system and sends the function program of MCU to other equipment for work;

3. Storage battery: used to store electric energy and provide electric energy for load;

4. If the voltage of the inverter load is AC 220, it will be used. Generally, the working voltage of solar street lamp is DC 12V or 24V, and inverter is not used.
