The battery in the LED street light system is a maintenance-free lead-acid battery, which mainly includes 38AH, 50AH, 65AH, 80AH, 90AH, 100AH, 120AH, 150AH, 200AH, etc. The service life of the solar battery has become the key to the normal use of LED street lights. LED street lamp manufacturers are a kind of solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, LED street lamps will become the choice of road lighting energy-saving transformation. LED street light is a high-efficiency solid-state light source formed based on a semiconductor PN junction that can emit light with weak electric energy. Under a certain forward bias voltage and injection current, the holes injected into the P area and the electrons injected into the N area are in After being diffused to the active area, photons are emitted through radiation recombination, which directly converts electrical energy into light energy. factor.

So let's take a look at the characteristics of solar cells.
Ordinary lead-acid batteries are mainly suitable for maintenance or low-end occasions due to frequent maintenance and high environmental pollution. Although alkaline nickel-cadmium batteries have good low temperature, overcharge and overdischarge performance, they are only suitable for special occasions due to their high price. With the widespread application of solar photovoltaic power generation systems, more and more people pay more and more attention to batteries as its supporting batteries.
Solar cells should have the following characteristics
1 Good deep cycle capability, good charge and discharge capability.
2Long life, special process design, long life battery is guaranteed by gel electrolyte.
3Suitable for different environmental requirements, such as high altitude, high temperature, low temperature and other conditions, the battery can be used normally.
The working principle of solar cells
During the day, sunlight shines on the solar modules, so that the solar modules generate a certain range of DC voltage, which converts light energy into electrical energy, and then transmits it to the intelligent controller. Through the overcharge protection of the intelligent controller, the electric energy of the solar module is transferred to the battery for storage. Storage requires batteries. The so-called battery is an electrochemical device that stores chemical energy and emits electrical energy when necessary.
The main components of lead-acid batteries are as follows:
Anode plate (lead peroxide. pbo 2)-active material
Cathode plate (sponge lead). pb)-active substance
Electrolyte (dilute sulfuric acid)-sulfuric acid (H2SO4) water (H2O)
battery case
Isolation board
Others (liquid port plugs, covers, etc.)
1. It has good deep cycle capability, overcharge and overdischarge capability;
2. The special process design and gel electrolyte can ensure its service life;
3, can adapt to different environmental requirements, such as high altitude, high temperature, low temperature environment can be used normally.
A solar cell is an electronic device that stores chemical energy and releases electrical energy when necessary. Sunlight during the day causes the battery modules to generate a certain amount of DC voltage, convert light energy into electrical energy, and then transmit it to the intelligent controller. Charge protection, and then store the transmitted electrical energy into the battery.
