The battery in the LED street lamp system is a maintenance free lead-acid battery, mainly including 38AH, 50AH, 65AH, 80AH, 90AH, 100AH, 120AH, 150AH, 200AH, etc. The service life of the solar cell has become the key to the normal use of LED street lamps. LED street lamp manufacturer is a solid cold light source, which has the characteristics of environmental protection, pollution-free, low power consumption, high luminous efficiency, long life, etc. Therefore, LED street lamp will become the choice of road lighting energy-saving transformation. LED street lamp is an efficient solid state light source based on semiconductor PN junction, which can emit light with weak electrical energy. Under a certain forward bias voltage and injection current, holes injected into the P area and electrons injected into the N area diffuse to the active area and emit photons after radiation recombination, directly converting electrical energy into light energy. Factor. LED street lamp is an efficient solid state light source based on semiconductor PN junction, which can emit light with weak electrical energy. Under a certain forward bias voltage and injection current, holes injected into the P area and electrons injected into the N area diffuse to the active area and emit photons after radiation recombination, directly converting electrical energy into light energy. So let's take a look at the characteristics of solar cells.

Ordinary lead-acid batteries are mainly suitable for maintenance or low-grade occasions due to frequent maintenance and heavy environmental pollution. Although alkaline nickel cadmium battery has good low temperature, overcharge and overdischarge performance, it is only suitable for special occasions because of its high price. With the wide application of solar photovoltaic power generation system, as its supporting battery, more and more people pay attention to it.

Solar cells should have the following characteristics

1 Good deep circulation ability and good charge discharge ability.

2 Long life, special process design, long life battery is guaranteed by colloid electrolyte.

3 Suitable for different environmental requirements, such as high altitude, high temperature, low temperature and other conditions.

Working principle of solar cell

In the daytime, the sunlight shines on the solar modules, which can generate a certain range of DC voltage, convert the light energy into electrical energy, and then transfer it to the intelligent controller. Through the overcharge protection of the intelligent controller, the electric energy of the solar module is transmitted to the battery for storage. Storage requires batteries. A battery is an electrochemical device that stores chemical energy and emits electrical energy when necessary.

The main components of lead acid battery are as follows:

Anode plate (lead peroxide. pbo 2) - active substance

Cathode plate (sponge lead). Pb) - Active substance

Electrolyte (dilute sulfuric acid) - sulfuric acid (H2SO4) water (H2O)

Battery housing

Isolation plate

Others (liquid port plug, cover, etc.)

1. It has good deep circulation ability, overcharge and overdischarge ability;

2. Special process design and colloidal electrolyte can ensure its service life;

3. It can adapt to different environmental requirements, such as normal use in high altitude, high temperature and low temperature environments.

Solar cells are electronic devices that store chemical energy and release electrical energy when necessary. The sunlight exposed in the daytime makes the battery module generate a certain amount of DC voltage, which converts the light energy into electrical energy, and then transmits it to the intelligent controller. Charge protection, and then store the transmitted electric energy into the battery.
