Constant Current LED Drivers

By implementing constant current LED Drivers into a lighting system, a lighting designer can intentionally drive a specified current through the system. This makes them essential when directly powering LED loads. With a fixed output current and variable output voltage based on the LED load, these drivers can accommodate a range of LED configurations, allowing for versatility and optimal performance.

FAQs

What are constant current LED drivers? ›

What is a constant current LED driver? As the name suggests, a constant current LED driver supplies a carefully controlled current flow across a given range of output voltages. Such LED driver power supplies quote the nominal continuous current output in mA or A, and the voltage range over which it operates.

What is driving LED with constant current? ›

Advantage of using a constant current LED driver

They avoid violating the maximum current specified for the LEDs, therefore avoiding burnout/thermal runaway. They are easier for designers to control applications, and help create a light with more consistent brightness.

How do you calculate constant current LED driver? ›

Check the LED datasheet and follow the steps below:
  1. Check the LED V-I curve, find the voltage on the curve according to the driving current. ...
  2. Multiply this voltage to the number of LEDs in one string. ...
  3. Allow for the LED production tolerance by calculating the ratio between the LED's typical and maximum voltages.

What is the difference between LED driver and LED power supply? ›

LED power sources that provide a “constant-current” output have typically been referred to as LED drivers. In the past, AC-DC power supplies that provided a regulated “constant-voltage” to LEDs were referred to as LED power supplies. Today, the terms “LED driver” and “LED power supply” are used interchangeably.

Do I need a constant current LED driver? ›

Choosing constant current LED drivers is the best option if you are building your LED lighting project. As their current is limited, the life of the luminaire can be extended at lower temperatures when using the rated output current.

Do I need a constant voltage or constant current LED driver? ›

If you were planning on using the driver to power an individual bulb, or to run numerous bulbs in series, you would need to ensure that you get a constant current driver. If however you were planning to run multiple bulbs in parallel, you would require a constant voltage driver.

What is the advantage of constant current LED driver? ›

Advantages of using a constant current LED driver

For the designer, they are easier to design the layout of LED module and help to create lights with more consistent brightness. Due to its characteristics, it is more suitable as a power source for street lights , flood lights, stadium lights , industrial lights, etc.

How do LED drivers work? ›

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.

Which driver is best for LED lights? ›

Splash-proof drivers with an IP rating of 65 are best suited for bathrooms and kitchens use (Protected from low pressure water from any direction). Waterproof drivers with an IP rating of 67 (Protection from immersion between 15cm and 1m in depth) or above, are best suited for outdoor use.

Can I use an LED driver as a power supply? ›

So while an LED driver may sometimes be suitable as a substitute power source for other devices - AC DC sources will usually remain the better option due to their greater wattage capabilities and power supply voltage options better suited for most applications.

Is an LED driver just a transformer? ›

A LED transformer is a power supply used in conjunction with LED lighting systems. Unlike LED drivers, LED transformers operate with a higher output wattage. As a result, a LED transformer can power larger, longer lighting systems.

What are the advantages of constant current LED driver? ›

These drivers are also very reliable when it comes to maintaining a constant brightness because they can more easily maintain a consistent light output. As a result of all these benefits, thermal runaway is also minimized. One major disadvantage to constant current drivers is that they can be much more costly.

What is the difference between constant current and constant voltage LED driver? ›

A constant current driver is the best way to drive high power LEDs as it maintains a consistent brightness across all LEDs in-series. Constant voltage drivers on the other hand are designed for a single direct current (DC) output voltage.

What are the two types of LED drivers? ›

TK: There are two main types of external LED drivers: constant-current and constant-voltage. Each type of driver is designed to operate LEDs with a different set of electrical requirements: Constant-current drivers power LEDs that require a fixed output current and a range of output voltages.

What is the difference between PWM and constant current LED? ›

With the constant current reduction method (CCR), the current continuously flows through the LED. Therefore, the LED is constantly on, unlike the PWM method, where the LED fluctuates between the on and off states. However, with CCR, you control the LED's brightness by varying or changing the current levels.
