Digital LED strips offer endless possibilities

Digital LED strips can be used for a variety of applications, including chasing lights and rainbows. A matrix of LEDs can also be created by placing many LED strips side by side. Such a matrix can be used to project graphics or videos. For such applications, you will need a special digital controller with software (see Accessories > Digital LED strip controllers).

By using this controller, you can specify where each LED strip should be placed, and then project graphics over the array of LED strips.

Digital LED: What is it?

Every digital led has its own driver IC and two data pins. A Digital LED has four pins, two for data and two for power. The Digital LED receives data from the controller IC and passes it to the next Digital LED in the series, using the power in parallel. Most regular LEDs don’t have data pins, and they use series or scanning power connections.

In short, it is also called Addressable RGB LED or ARGB LED based on its characteristics.

Why should use LEDs?

Multiple RGB LEDs can be used simultaneously with digital LEDs. The electronic engineer can save a lot of time by using Digtal LEDs in PCB layout, as well as use fewer ICs by using Digtal LEDs.

The traditional RGB LED has four pins, one for the cathode/anode and three for the R, G, and B circuits.

It will not be an issue if you use few LEDs, but as you use more LEDs, circuit routing becomes more challenging. Scanning is another common scenario when using multiple RGB LEDs. In addition to the complexity of routing, scanning is often used to light up different colors between RGB LEDs. LEDs sometimes blink depending on the scanning frequency.

Due to their built-in driver IC and non-scanning emission, Lumex Digital LEDs overcome these two limitations.

The implementation of Digital LEDs differs from traditional R/G/B LEDs. Initially, the circuits are different. There are two data pins for receiving data and passing it on to the next LED(s) and two power pins for cathode and anode.

Keep in mind that Digital LEDs use power in parallel; in other words, the current is accumulated. To calculate the maximum power consumption of 66 Digital LEDs, we need 1A.

The next step in using Digital LEDs is to send data to tell them to light up. By sending 24 bits of data in sequence, the control signal is straightforward.
