The relationship between solar outdoor LED lights and batteries

Corporate News / 2023-10-17

The voltage of solar outdoor lights is generally 12 volts or 24 volts, and in special cases, there are also 36 volts or 48 volts. Solar street lamps are a type of lamp that uses new energy sources, does not pollute the environment, is easy to clean, can also be recycled, and is convenient to use. The voltage is generally determined based on the specific specifications and models of solar street lamps. The emitting part of solar outdoor lights is generally composed of multiple LED beads.

The voltage of LED beads comes in various specifications.

Generally speaking, the voltage of a single LED bead is around 3 volts. For different types of LED beads, the voltage may vary slightly. For example, the voltage of white LED beads is usually around 3 volts, while the voltage of color LED beads varies depending on the color.

In practical applications, in order to meet different lighting needs, multiple LED beads are usually connected in series or parallel. For example, when 24 LED beads are connected in series, the required voltage is 24 * 3=72 volts. If it is in parallel, the voltage does not change, but the current will increase accordingly.

The above information is for reference only. If necessary, we suggest consulting our engineers. So if the number of lamp beads and voltage and current are determined, how to choose a battery?

The method of selecting battery size based on the number of solar lamp beads mainly considers two factors:

1. Current of solar beads: Each solar bead has a specific current, usually measured in milliamperes (mA). Generally speaking, the higher the current of solar lamp beads, the higher their brightness, but at the same time, the higher the requirements for batteries. Therefore, when selecting a battery, it is necessary to consider the current size of the solar bead.

2. Power of solar lamps: The power of a solar lamp refers to the maximum power it can output at a specific voltage. When selecting a battery, it is necessary to consider the relationship between the power and current of the solar lamp to determine the optimal battery specification.

Specifically, the process of selecting a battery can be carried out as follows:

1. Calculate the total current of solar lamp beads: Add the current of all solar lamp beads to obtain the total current of the solar lamp.

2. Determine the voltage of the battery: The voltage of the battery should be equal to the total current of the solar lamp beads multiplied by the output voltage of the solar lamp.

3. Choose the appropriate battery capacity: The capacity of the battery should be equal to the total current of the solar lamp beads multiplied by the working time of the solar lamp. For example, if a solar lamp needs to work continuously for 8 hours, the capacity of the battery should be the total current of the solar bead multiplied by 8 hours.

In summary, when selecting a battery, it is necessary to consider various factors such as the current, power, and working time of the solar lamp beads to determine the optimal battery specification.
