Solar street lights are a lighting device that uses solar power to
generate electricity, which can provide lighting at night without
the need for an external power source. One of the core components
of solar street lights is the battery, which stores the energy
collected by solar panels during the day for use at night.
ECOLITE independently developed a new lithium-ion solar street lamp
patent design, battery integration is not easy to steal, improve
the conversion efficiency.
During the day, solar panels convert solar energy into electricity,
which is fed into a battery through a charge controller for
storage. At night, when the ambient light is insufficient, the
light control switch will automatically open, and the solar street
light will start to work. At this time, the battery will release
the stored energy and supply it to the LED lamp for lighting
through the control circuit.
First, lithium batteries have a high energy density and can store
more energy, thus extending the working time of solar street
lights.
Secondly, lithium batteries have a long life and can withstand
multiple charge and discharge cycles, reducing the frequency and
cost of replacing batteries.
In addition, the lithium battery is relatively lightweight, which
can reduce the overall weight of solar street lights and facilitate
installation and maintenance.
ECOLITE professional solar street lamp lithium battery
manufacturers, the use of new A product cell, factory direct sales,
more favorable prices, support custom senior solar street lamp
lithium battery.
