What is main difference between Digital and Analog LED strips?

What is main difference between Digital and Analog LED strips?

We start this blog with comparison below shows you the main differences between Analog and Digital LED strips.

 

  Analog Digital
Colors only one different for each LED
Controls on hardware level DMX SPI
Typical user control DMX console or software video software, live video stream, Art-Net, SD-card
Voltage 12V, 24V, 220V 5V
Typical number of LEDs per meter 32, 60, 80 30, 32, 42, 60, up to 144
Cut segment 3 or 6 LEDs 1 LED
Typical usage decorative lightning decorative lightning with video projection
Installation easy complicated
Typical current per meter of strip 1A at 12V, 0.5A at 24V 1.2A at 5V
Can be controlled using LED Strip Studio yes (additional LED DMX dimmers are required) yes

 

 

Analog LED strips

 

Generally, analog strips allow you to change color of the strip, but you can get only one color on the strip at once. They are ordinarily used to illuminate decorations in club, TV studios or buildings themselves.

Examples of use Analog LED Strips

Way of control Analog LED Strips

 

Analog strips are frequently controlled over DMX or using remote controls. In case you use single color analog LED strips (usually white), you are able to connect them directly into the power source.

But the most common way of controlling analog LED strips is over DMX signal. This allows you to change color of the strips using standard DMX lightning console (or software).

 

 

Voltage of Analog LED Strips

 

Typically, analog LED strips use 12V, 24V or 220V voltage. They are normally distributed in 5m rolls and use 60 LED diodes per meter (but there are also less or more LEDs per meter versions available).

 

Digital LED strips

 

Digital LED strips are also called video, dream or pixel LED strips. The main benefit comparing to analog LED strips is that you can control every single LED diode color separately. This allows you to use digital LED strips to display even video information. Traditionally, it is achieved thanks to additional chips (IC) assembled directly inside the LED diode or on the digital strip board.

Digital LED strips can be used to achieve amazing animated light effects in clubs, TV studios or even buildings. They can be used for decorations, but also for displaying video content for advertisement purposes.

 

 

Digital LED strips are great for any-shape LED screens. And yes, we can turn your car into an LED screen.

 

Digital LED strips are usually more complicated to control, since you have to provide video content for the LED strips. Users often use computer software, Art-Net, live video stream or SD card as a video source.

 

On hardware level the digital strips receive video information over SPI (Serial Protocol Interface). Every single LED of digital strip uses one chunk of RGB data in SPI data packet.

 

Now, pay attention. You have a little issue with the digital LED strips SPI communication – there is not only one standard. There are many control IC chips and every one of them uses different kind of SPI signal. The most common types are WS2811, WS2812, TM1803, TM1809, SK6812, UCS, APA102 or APA104. LED Strip Studio system supports all common types of IC.

 

Way of control Digital LED Strips

 

LSS scheme of use

LSS 3 allows you to send it through output using 4 independent SPI outputs. Each one of them can control up to 1000 LEDs. And that is a huge difference!

 

Typically, the SPI controllers receive video information over Ethernet cables from computer software or Art-Net. But there are also controllers using SD-card or live video stream (e.g. from HDMI) as a video source.

 

Voltage of Digital LED Strips

 

Digital LED strips usually work at 5V voltage, although there are also some 12V or 24V versions (these allow controlling only 3 LED as one pixel). We often use 42 LEDs/m version, but you can find many kinds of digital LED strips, anyway.
