5200mah Li Battery 3PCS Bulbs Solar Wall Light For House

Solar Powered Solar Wall Light For House 3 PCS 5200mah Li-Battery Bulbs

Product Introduction

Characteristics

This bulb has a large diameter and is very suitable for Europe. It has a good grip. Moreover, the 18650 battery imported from Japan is used. This battery has many advantages. It not only has large capacity, long service life, high voltage and no memory effect, but also has small internal resistance, high safety performance and wide application range. The battery is guaranteed for up to two years and can be used for about 3-5 years. The appearance of the bulb is specially studied by the designer. It has the advantages of using patents and appearance patents, and the average service life is as long as 10-15 years.

Theory

In today's society, more and more solar power generation devices appear in people's vision. As long as there is sunlight, electric current will be generated, which is too convenient for our daily life. Solar cell is a device that converts solar energy into electric energy by using the photoelectric effect of semiconductor materials. Then the raw material of solar cell is silicon. As a semiconductor, silicon has an important property. That is, when light shines, the electrons in the outer layer of silicon will get energy from the light to form free electrons. And leave a hole in the original position to form an electron hole pair. If this group of electron holes generate an electric field in the region of the PN junction, the holes will move to the p region and the electrons will move to the N region under the action of the electric field force. In this way, there will be a potential difference between the two ends of the PN junction. If we connect the two ends of the PN junction to the electrode and then connect it, a current will be generated.

Advantage

1. Different from the traditional type of solar cell module, each bulb / lamp of this model has a built-in battery, with completely independent power consumption and easy management.

2. The advanced model has a power indicator on the lamp body to indicate how much of the total power is in the sun during the day and how many hours it can be maintained at night, so as to provide users with friendly design.

3. The efficiency of solar panels is 1.20 times that of ordinary panels.

4. Dual charging conditions: solar panel or any 5v-6v DC power supply 5. High brightness: illuminate a room of 10-15m2, and the light output is equivalent to 7W compact fluorescent bulb.

Service

We guarantee that the energy thermal surface power lamp (LTSHE) is free of defective materials and operates under normal wear, installation, accommodation and service conditions for three years from the date of customer acceptance of the product. If the module does not meet this warranty, we will repair or replace the product within three years and one year after the delivery date to the customer. This guarantee is valid only when the customer owns the product.

Attention

1. If the light bulb doesn't light all the time, please don't panic. Immediately check whether the switch button has been turned on or how the solar panel stores electricity.

2. If the solar panel cannot be charged, be sure to check whether there is dust or dirt above the solar panel to prevent charging.

3. As long as there is a light source, the solar panel can realize continuous charging.

4. When connecting the cable, make sure that the label is completely consistent with the connector, otherwise the battery will not be able to complete charging.
