The solar street lamp converts the natural light source into electric energy for lighting. It has the advantages of energy-saving insurance, environmental protection and durability, low maintenance and clean without contamination, and has been praised by all walks of life. Solar street lamps can always be seen in large and small public places such as urban paths, park communities, and city streets. They have become the main force of ancient lighting and always play an important role
The failure rate of solar street lamp is very low, and its service life is relatively long, but in the solar street lamp, there is a component that can be easily lost, the service life is only about 5 years, that is the battery. Individually, the battery of the solar street lamp is buried underground, but do you know why the battery is buried underground? What's the use of being buried in the ground?
It is important to take the buried type is related to the type of battery, solar street lamp battery colloidal battery, lead-acid battery, large volume, weight is heavy but settled in the lamp cap or air, so can only take the buried type.
The wiring on the back of the solar panel is a reverse buckle design, which can be gently pried open with a screwdriver. The wiring of the solar panel (red cap is connected to the positive pole line, black cap is connected to the negative pole line) corresponding to the positive and negative pole line separated from the black cap of the lithium integrated battery, and the wiring should be wrapped with electrical tape. The LED street lamp is a kind of efficient solid-state light source based on semiconductor PN junction formed with weak electric energy that can emit light, in a certain forward bias voltage and injection current, injected into the hole in the P region and injected into the N region of electrons in the diffusion to the active region after radiation compound and emit photons, the electric energy directly into light energy.
It is a solid cold light source, with environmental protection, no pollution, less power consumption, high light efficiency, long life, and other characteristics, therefore, LED street lighting will become the best choice for energy-saving transformation. Solar street lamp LED lamp head wire lithium control battery white cap separated, wiring attention to use electrical tape wrap. So, what are the benefits of buried batteries?
1, security
The battery is an important part of the solar street lamp, the price is relatively expensive, naturally will be targeted by some criminals. Therefore, the battery must be buried deep underground, can not be buried too shallow, in order to provide convenience to ring horse.
2. Avoid battery water
The battery is very afraid of water, it is true that the outer layer of the battery has been waterproof, but in order to better play a waterproof role, it is necessary to use cement to cover the treatment around, and further strengthen the waterproof method. There is also local construction to take the device waterproof battery box waterproof.
3, antifreeze
Battery individual at minus 30 deg C -60 deg C may be abnormal use, but in a very cold environment, it will land battery endurance ability, very individual will end the working condition, so that if in the cold north to install solar street light, it is necessary to bury the battery in more than 2 meters deep, so it may adhere to a certain temperature.
