What is an LED driver module?

An LED Driver Module (short: LED driver) is an electrical device used to power Light Emitting Diodes (LED). LED drivers are either constant current or constant voltage. Constant current drivers can power LEDs directly.

What does a driver do for LED lights?

In summary, LED drivers convert higher voltage, alternating current to low voltage, direct current. They also keep the voltage and current flowing through an LED circuit at its rated level. For the aforementioned reasons, every LED light source requires a driver.

What happens when a LED driver goes bad?

LED drivers rectify higher voltage alternating current to low voltage. If you have a good LED and a bad operating LED driver your high bay LED Lights won’t be functional for long. Most LED failures are not from the LED, but from the driver. Usually the circuits burn out and fail.

Can I use LED without Driver?

Every LED light source requires a driver. The question should be whether or not you need to purchase one separately. Some LEDs already include an integrated driver within the bulb. LEDs designed for household use (bulbs with E26 / E27 or GU24 / GU10 bases and that run on 120V) typically already include a driver.

What is the difference between LED driver and power supply?

Simple Definition: What is the Difference between Power Adaptor and LED Driver. LED power sources that were designed to regulate the current output are called LED drivers, while the conventional AC-DC power supplies that were used to providing a “constant- voltage” are mostly referred to as LED power supplies.

What is the difference between a transformer and an LED driver?

Electronic transformers work in a similar fashion to LED drivers, but they tend to allow for larger output power. In other words, long-length strips of LED lights may require a power supply in excess of 200 W, and since LED drivers may be limited in power output to 100 or 200 W, an electronic transformer may be needed.

What are the symptoms of a bad LED driver board?

If you restart your TV set while it is on, it may be a bad mainboard. The LED driver is similar to the LCD TV backlight inverter, so the most common problem here is that you don’t have the lighting from the LED driver. Your TV is turned on, you may have sound but you have no image on the screen and no backlights.

Can you fix an LED driver?

LED Driver Replacement is a difficult process. When an LED fixture fails you need to either purchase a new fixture or replace the driver. In most scenarios it’s the LED driver that needs replacement (LED components have a longer shelf life).

Do I need a transformer for LED lights?

All mains powered LED bulbs require a transformer. Depending on the bulb type, the transformer/driver may be built in to the bulb casing or may be located externally. The purpose of the transformer is to reduce mains voltage (240V) to the desired level relative to the bulb being powered (e.g. 12V or 24V).

Can a LED driver be used as a power supply?

Conventional AC-DC power supplies and DC-DC converters provide an output that is regulated to provide a “constant-voltage.” However, LEDs work most efficiently and safest with a “constant-current” drive. Today, the terms “LED driver” and “LED power supply” are used interchangeably.

Is a driver a power supply?

An LED driver is a self contained power supply which regulates the power required for an LED or array of LEDs. The light emitting diodes are low energy, lighting devices with a long lifespan and low energy consumption, hence the requirement for specialized power supplies.
