Led drivers basics

We recommend choosing a driver with a wattage capability at least 10% higher than the wattage the LED tape requires to ensure a longer lifespan. For example, 5m of 6w LED tape requires 30 watts. We would recommend using a driver with an output capability of 33 watts or more to power this tape.

How do I choose an LED driver for my LED?

5 Important Factors When Buying LED Drivers

Output Voltage / Current. First, consider the voltage requirements of your light.
Input Voltage / Current. Next, consider the voltage supply of the location you'll be using your light. ...
Max Wattage. Lastly, consider the wattage requirements of your light. ...
IP Ratings.

How do LED drivers work?

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 are the components of LED driver?

Components of Led Driver Circuit

Electrolytic capacitor (non-polarized 2.2μF)
Four resistors (1KΩ,10KΩ, 22KΩ, 390KΩ)
Bridge rectifier.
Zener diode (4.7V)
An LED (Bright white LED)
And, a polarized capacitor (47μF)

What happens if you overload an LED driver?

Therefore, if the voltage deviates more than 10%, the LED bulb is fused off. Subsequently, the electronic parts inside the LED bulb get damaged from the voltage spike. Excess voltage wears out LED drivers and distribution panels prematurely.

Does polarity matter for an LED driver?

LEDs are electrically polarised and will only operate correctly when their positive terminal (also known as the anode) is connected to the supply positive and their negative terminal (also known as the cathode) is connected to the supply negative. LED connection polarity must be strictly observed!

How do you match LED driver to light?

Use an LED driver with at least the same value as your LED(s). The driver must have a higher output power than your LEDs require for extra safety. If the output is equivalent to the LED power requirements, it is running at full power. Running at full power may cause the driver to have a shorter life span.

Can I use a different LED driver?

Unlike fluorescent ballasts, LED drivers are not standardized, so they are not interchangeable. They can vary in terms of output characteristics, electrical safety rating, input voltage, programmability, temperature rating, electromagnetic interference (EMI), dimming interface and form factor.

Which is the best LED driver?

Is an LED driver just a transformer?

Although similar in operation, LED Drivers are different from transformers. Whereas transformers convert an “input” voltage to an “output” voltage, both functioning on an Alternating Current, LED Drivers convert AC to DC and subsequently supply a constant current to the LED.

Does an LED driver need a ground?

A.K.A. as long as you're feeding it DC power your lights will work just fine, grounded or not. The only way a cheater plug or an ungrounded connection will affect your lights is if a power surge blows your lights out!

Do LED drivers convert to DC?

In an LED Light the driver does all the heavy lifting. Whether its an LED Corn light bulb or an LED fixture it has a driver inside. That driver takes input from the building in alternating current or ac and converts it to direct current or dc. In your home that means from 120vac down to 36vdc or 48vdc.

What is TA and TC in LED driver?

TA = Ambient temperature. This is the temperature of the environment, still air. TC = Case temperature. This is the temperature of the case of the semiconductor device.

How many types of LED drivers are there?

The main two types of LED drivers are constant current drivers and constant voltage drivers.

What voltage are LED drivers?

LEDs are designed to run on low voltage (12-24V), direct-current electricity. However, most places supply higher voltage (120-277V), alternating current electricity.

What is the life expectancy of an LED driver?

The driver is the heart of the LED light, and driver life can range from 10,000 to over 50,000 hours, depending on the design features, heat sink efficiency, capacitor construction, and overall quality.

Why do LED drivers flicker?

What makes LED lights flicker? Well… put simply, LEDs flicker when their light output fluctuates. This fluctuation happens because your dimmable light-emitting diodes are designed to switch on and off at very high speed.

Is 12V too much for LED lights?

Quite intuitively, providing more than 12V DC on a 12V LED strip is not a good idea, because you may cause the LED strip to be over-driven, burning out the diodes or causing excessive heat buildup that can damage both the circuit and on-board components.

Which leg of an LED is positive?

LED polarity The voltage supply side of the diode is the positive (+) side, this is called the anode. The negative side is called the cathode.

Is an LED driver just a power supply?

The LED driver is a self-contained power supply which has outputs that are matched to the electrical characteristics of the LED(s). This helps avoid thermal runaway as the constant current LED driver compensates for the changes in the forward voltage while delivering a constant current to the LED.
