The driver ensures that the LED light is continuously supplied with power, i.e., like a power supply unit. However, the driver also provides that this current does not have peaks. This ensures that the LED luminaire does not have a shortened life or reduced reliability.
To ensure this, the driver must be electrically compatible with two voltages. This conversion must be done with the lowest possible losses, a high power factor, and a low generation of harmonics in the network.
In addition, to maintain the power supply to the LEDs without fluctuations, the driver itself must have excellent stability and protection against voltage spikes to which electrical networks are exposed.
What types of LED drivers are there for LED lights?
There are two types of LED drivers: voltage-controlled and current-controlled. Although both are, the current model is more often used for different purposes.
There are unique models for home use, closed environments (corporate, commercial), and industrial service. Each offers a luminaire that best suits the needs and provides the most suitable lighting.
How to choose the LED driver?
Since it is a fundamental and directly decisive component for the certification of the life of an LED luminaire, it is essential to evaluate some parameters for the function of the driver.
Among these factors, the most important is the power factor and efficiency. According to Brazilian standards, the power factor of a driver should always be above 0.92. The efficiency of an LED driver should be checked to ensure it is in the 83% to 93% range.

Constant Voltage LED Drivers
LED power supplies: Constant Voltage LED Drivers, LED lights that operate with a constant voltage driver to require a consistent amount of output voltage, typically light output of 12V DC or 24V DC.
Higher voltage (120-277V)
Output current 1A 2A 3A 5A 10A 12A 15A 20A 25A 30A
Constant current LED Driver
In constant current LED drivers, typically the current output is 700mA, and the output voltage range is 4-13V DC (volts of direct current). The constant current LED module operating at constant current must NOT be connected in parallel, only in series.

How the LED light works: constant current LED circuit
Connect one of the wires in the first module (-) and make the connection (+) and (-), connecting from one module to the last, while one wire (+) goes outside the circuit and connects to the previous module.
The most important thing is that power sources should always be connected in series, never parallel.
