Dimmable LED drivers are necessary to control the power flow into the LED. By doing this, the brightness of the LED can be changed by varying the electrical current flowing into it.

LEDs can provide intense light while generating little heat. This is partly because of its technology, which uses a semiconductor die to transform electric charge into light directly.

LEDs produce light as a byproduct of the low-voltage energy that travels through a semiconductor die in one direction. As a result, LEDs have a long lifespan and produce less heat, which is a significant energy conservation and sustainability benefit.

Read on to learn what you must know about LED light drivers so you know what to consider before buy LED drivers online and other factors!

Let's explore the types of LED drivers!

  • Constant Voltage And Constant Current:

Depending on their mechanism, constant voltage, and current LED drivers are the two basic types of LED drivers.

Constant voltage drivers adjust the current to keep the voltage stable. They are wired in parallel and have a voltage rating of V or DC. A constant current driver keeps the LED's electrical current flowing continuously by adjusting the voltage. These drivers always have series wiring and have amps (A) or milliamps (mA) values.

  • Low Voltage And High Voltage:

Low-voltage LED drivers use low DC power input, typically 5 VDC to 36 VDC. These models have greater dimming and output settings and are efficient. They are chosen for smaller applications as a result.

High voltage drivers, called AC LED drivers, require a higher DC power input of between 90 and 277 VDC. These drivers consume more power and supply the LED with a higher current. As a result, they are typically advised for use in significant general illumination projects, such as lighting for homes or businesses.

  • Dimmable And Non-Dimmable:

Not all LED drivers have the ability to dim. If an LED driver is compatible with dimmers is a different factor to consider. You should seek an LED driver with or without a dimmer depending on your project and desired amount of customization.

Drivers that can change phase forms and produce a dimming effect have special circuitry built into them. Non-dimmable drives, however, have on and off switches.

Here are things you need to consider when selecting an LED driver!

  • Output Voltage:

If you have more than one LED, you must sum the voltage requirements for each LED to get the total. The output voltage should be more than LEDs require for continuous current users. Either 12 or 24 volts are needed for the LED to function. You must utilize a 12-volt driver for operation on 12 volts and a 24-volt driver for operation on 24 volts.

You should consider the current output, defined and labeled in amps or milliamps while selecting an LED driver for a constant current LED that requires a fixed output current and range of output voltage.

  • Input Voltage:

The most crucial factor to consider is the current supply to the LED light since you need to be aware of the input voltage that will be used in a certain location, like within the light, and the same output voltage that will be drawn.

Hence, harm may result if there is no link between the input and output voltage. For instance, motorists choose a wide range of input voltage to guarantee the light's brilliance, particularly at night.

  • Maximum Wattage:

You must also consider your luminaire's wattage requirements. According to certain studies, LED drivers should be paired with LEDs that consume 20% less power than the maximum rated wattage. This does not, however, apply to AC LED drivers, which, when accounting for AC as well, can approach 50%.

In this situation, the driver should not be used with an LED whose maximum wattage is equal to or more than the driver's to prevent overloading the driver part.

  • Efficiency:

Efficiency is the most crucial consideration when choosing an LED driver. Since efficiency is measured as a percentage, a constant voltage and current driver operate at a range of 90%, or 0.9 efficiencies, and the LED driver operates at this level.

Installing extra LED lights will help the driver perform more efficiently if the low ripple is less than 50% or 0.5, which is considered inefficient.

  • Dimming:

Choosing to buy LED Driver DMX will help you change the brightness, and even you can use it to create unique lighting effects. There is always a specification of the power source, which will determine whether they are dimmable.

When used with the input AC, a better dimmable driver can regulate the high-voltage power supply. This will alter the voltage and can also be used to manage dimmer power supplies, allowing for duty cycle-based output current regulation.

Although it sounds a little dramatic, LED drivers are a component of LED technology. In addition, these factors will help you to consider the right selection of LED drivers for your application.
