LED is widely recognized as a highly energy-efficient and cost-effective lighting technology with the potential to fundamentally alter the future of the global lighting industry.
As a result, it is critical to comprehend LED in depth. To get right to the point, LED drivers are a critical but perplexing component of LED technology. LED drivers are available in a variety of shapes and sizes. As a result, here’s a quick post explaining the differences, what makes LED Drivers different, and what you should think about when selecting the LED driver(s) for your lighting application.
WHAT IS AN LED DRIVER?
A LED driver is the beating heart of any LED circuit. It is a piece of electrical equipment that controls the power of an LED or a string of LEDs. Failure to use one will result in system failure.
The Forward Voltage (Vf) of a high-power LED changes with temperature, making the use of LED drivers “unavoidable” in order to protect your LEDs.
WHAT IS FORWARD VOLTAGE?
Forward Voltage (Vf) is the “negative voltage” required for every LED to function properly. It is the voltage needed by the light-emitting diode to conduct electricity and light up. As the temperature rises, the LED’s Vf decreases, causing the LED to draw more current. The LED will continue to heat up and draw more current until it burns out. This is known as Thermal Runaway. The LED driver is a self-contained power supply with outputs that correspond to the electrical properties of the LED (s). The constant current LED driver compensates for changes in forward voltage while delivering a constant current to the LED, which helps to avoid thermal runaway.
THINGS TO THINK ABOUT BEFORE CHOOSING AN LED DRIVER
- What type of LEDs will be used, as well as their quantum?
- Will I require a constant current or constant voltage LED driver?
- What type of power (DC, AC, batteries, etc.) will be used?
- Are you trying to avoid AC? See how an AC driver can help you!
- Is there a limit to the amount of space available?
- What are the primary objectives of the LED application?
- What will its size, cost, efficiency, performance, and so on be?
- Will I require any special features such as dimming, pulsing, microprocessor control, and so on?
DO YOU KNOW THE DIFFERENT TYPES OF LED DRIVERS?
Drivers are classified into two types: those that use low-voltage DC input power and those that use high-voltage AC input power. Off-Line or AC LED drivers are LED drivers that use high-voltage AC power.
In most cases, a low-voltage, DC input LED driver is recommended. Low-voltage direct current (DC) drivers are recommended because they are extremely efficient and dependable. When compared to high-voltage AC drivers, smaller applications have more dimming and output options, giving you more flexibility in your application.
