Do all LED lights need drivers?
2020-02-14

LED drivers (also known as led power supply) are similar to fluorescent lamp ballasts or low-voltage bulb transformers: they provide the correct power for the LEDs to perform optimally. Below, we discuss do all LED lights need drivers, and which type of drivers might be needed.


A power led driver is required for each LED source. The question should be whether you need to buy a separate drive for your lamp or some LED devices already contain a drive. General light companies will have matching drives for you to choose from.


External led driver transformer are mainly divided into two types, constant current vs constant voltage led driver. All driver is designed to operate LEDs with different electrical requirements. You must match the input/output requirements of the old driver as much as possible when you will replace a driver. Such as Smarts drive difference is as follows


The constant current driver supplies power are use for the LEDs with a fixed output current and a range of output voltages. In the following example of SMT-018-0350CW, the current output is 350mA and the output voltage range is 10-18V DC (DC voltage).


Constant voltage drivers are used to power LEDs with fixed output voltage and maximum output current. These LEDs require a stable voltage, typically 12V DC or 24V DC. In the example following, the output voltage is 24V DC and the maximum output current is 4.0A.
