What is an LED driver

An LED driver is a power supply that converts alternating current (AC) into direct current (DC) specifically for use with LED lights. Many LEDs require DC power to operate, and an LED driver ensures that the correct amount of power is supplied to the LED fixtures.

Not all wall outlets provide DC power, which is why an LED driver is necessary. The driver steps down the voltage from the outlet (usually 120 volts AC) to a lower voltage that is compatible with the LED lights (usually 12 or 24 volts DC). In addition, the driver regulates the current going to the LEDs so that they do not burn out.

Types of LED driver

There are two main types of LED drivers: constant current and constant voltage. Most LEDs require a constant current driver, but some can work with either type.

Constant current drivers:

A constant current driver supplies a consistent flow of current to the LED lights, regardless of fluctuations in the input voltage. This is the most common type of driver used with LEDs.

Advantages of using constant current drivers:

A constant current driver is the key to avoiding burnout and thermal runaway when using high powered LEDs.

They are easier for designers, control applications so your lights can produce more consistent brightness levels in different parts of a building or space.

Constant voltage drivers:

A constant voltage driver maintains a consistent output voltage, regardless of fluctuations in the input current. This type of driver is less common and is typically only used with LEDs that have built-in current regulation.

Advantages of using constant voltage drivers:

Constant voltage is a much more familiar technology for design and installation engineers. This can result in lower costs, especially when applied to larger scale applications.

Choosing the right driver

Now that you know the basics of LED drivers and the different types available, it’s time to learn about how to choose a LED driver that is the right one for your needs. Here are a few things to consider:

When choosing an LED driver, the first thing you need to do is to determine the type and number of LED lights you'll be using in your setup. If they're wired series, such as with ground or deck lighting-you will require a constant current driver to drive them; but if paralled together (such as by installing long lengths) then an constant voltage one is necessary too.

Then, determine the required output current. The output current is determined by the number of LEDs and the forward voltage of the LEDs. The forward voltage is a measure of the voltage drop across an LED when it is turned on. To find the forward voltage of your LEDs, consult the manufacturer's datasheet.

Next, you need to determine the required output voltage. The output voltage is determined by the forward voltage of the LEDs and the number of LEDs in series. To find the output voltage, simply add the forward voltages of all the LEDs in series.

Once you know the required output current and voltage, you can select an LED driver that can provide those levels. Many LED drivers are adjustable, which means they can be dialed to the specific current and voltage requirements of your application.

When selecting an LED driver, it's also important to consider power efficiency. In general, more efficient LED drivers will result in lower power consumption and lower operating costs. The most efficient LED drivers on the market are typically those that use pulse width modulation (PWM) to control the LEDs.

Finally, you need to consider the dimming compatibility of the LED driver. If you plan on dimming your LEDs, make sure to select an LED driver that is compatible with the dimmer you plan to use. Many LED drivers are not compatible with standard incandescent dimmers.

By following these simple steps, you can be sure to select an LED driver that's right for your application.

Other factors to consider

Milliamp Rating

You'll need to make sure that your light's amperage matches up with an LED driver. The most common ratings for these types of bulbs are 350mA or 700 mA, but it’s always best if you can find out what kind they use before putting in any energy!

Wattage Rating

The wattage rating of your LED driver should be greater than or equal to the total amount wired for lighting in order avoid damage. For example, if you have five 3-watt ground lights on a 15 watt system then there's no problem but when going up from here things get more complicated so make sure.

Output Voltage

Make sure the LED driver output voltage is compatible with your light. Some drivers have a wide range of compatibility but others may only offer specific voltages that could potentially damage an electrical component if used incorrectly so be careful.
