What is an LED Driver?

Please note: we have Australia's largest range of LED light drivers for online shopping and wholesale purchase.

Introduction

LED lighting is becoming increasingly popular for a number of reasons. LED lights are generally safer and more resilient than other lighting fixtures, and also consume less energy and last far longer. So, it's easy to see why they are such a good choice.

In order to work properly, LED lights need a driver. What's a driver, you may well ask? Well, simply put, it's an electrical device that supplies the power needed to run the lights. If you're not completely familiar with these marvels of modern lighting here is a guide to explain all you need to know.

What is an LED Driver?

An LED driver (also known as an LED light driver) is an instrument that transfers power to an LED light or an array of LED chips. It converts the mains 240V power into the correct voltage and current that is usable by the LED light. There are two types of LED light drivers: constant voltage output and constant current outout.

Does All LED Lights Need LED Drivers?

The answer is yes, but it is extremely important to understand that some LED lights already come with LED drivers built in, and some don't. Those with LED drivers built in will be rated 240V and can be connected directly to the 240V mains power. Those without LED drivers built in (called low voltage lights) will be rated 12V or 24V, and will require an external LED driver to be connected between the 240V power and the LED light. A guide on how to connect low voltage lighting can be found on Installing Low Voltage Garden Lighting.

How Do LED Drivers Work?

An LED driver provides the appropriate current to correctly power the LED light. The self-contained LED driver is able to meet the demands of the light because its electrical properties alter along with temperature. By converting power into the most appropriate voltage, the driver will power the light properly. Without the correct driver, the light could become too hot or unstable for use.

The main two types of LED drivers are constant current drivers and constant voltage drivers. Both supply power to the LED fixtures, but work differently depending on the kind of lights you plan to use.

Constant Current Drivers

Constant current drivers supply a variable voltage of power depending on the demand. They are usually used when each light requires its own driver and the number of LED lights that need to be powered is known before setting them up. Track lights and downlights are often powered by a constant current driver.

Constant Voltage Drivers

Constant voltage drivers provide a fixed voltage of current and maintain a constant controlled current to LEDs. They are often employed when there needs to be a greater flexibility in the number of LED lights used.

Dimming in LED Drivers

Certain types of LED drivers are able to control dimming features in LED lighting set ups. New electronic drivers are able to implement dimming systems, allowing a reduction of current while maintaining colour and temperature.

Colour Correction

Sophisticated LED drivers are also able to manage colour change and sequencing, either by dimming differently coloured LED lights or by working through a specific colour sequencer. A sequencer works by receiving a voltage output and then changing it into a three colour (red, blue and green) palette that be mixed up into any number of different shades.

As we can see, LED drivers are an adaptable, flexible and reliable way to power a collection of LED lights. Whether the LEDs are being used in commercial, industrial or residential spaces, the correct driver offers the full range of LED lighting practicality.
