Each single LED needs to operate at a certain voltage and current. When we connect many LEDs in series, the current through the circuit is the same, and the total voltage is equal to the sum of the voltages of each LED.

Usually, we prefer to use the constant voltage led drivers to drive the lamp, the advantages are as follows:

The voltage and current provided by the power system are unstable. After the LED is impacted, it may cause flicker or damage.

The power system provides high voltages of 110 Vac, 220Vac or higher, which is very dangerous to humans. If there is a leak, it is likely to pay the price of life, but using a constant voltage led drivers, you can convert the input 110V into the output 24V (low voltage) . When we touch the light, it is 24V.

The dimmable constant voltage led driver is always an important part of the LED lamp, and it is very convenient to maintain and has a great impact on the service life of the LED. Only by choosing high-quality constant voltage led drivers can the performance and life of LEDs be idealized.
