What is main difference between Digital and Analog LED strips?

What is main difference between Digital and Analog LED strips?

Firstly, we go through the main differences between analog and digital LED strips, to make sure, we fully understand these terms.

 

Analog LED strips :

  • all diodes are lit in one color in the LED strip
  • can be controlled by DMX
  • cut segment is 3 or 6 LEDs
  • easy to install
  • home decorations, TV studios, outdoors

 

Digital LED strips :

  • you can control each LED diode separately, creating various colors in one LED strip
  • can be controlled by video software, live video stream, Art-Net, SD-card
  • cut segment is 1 LED
  • more complicated to install
  • club interiors, TV shows, stage rental

 

Analog LED Strips

 

Color change

 

Analog strips allow you to have one color for the whole LED strip at a time. You can change the color anytime you want for the whole strip, but can’t  change it for a section of diodes.

 

Analog LED Strip

Analog strip can only have one color at the time.

 

Control system

 

 

Analog LED strips can be controlled by DMX. DMX is a signal used to control LED strips through the DMX unit. A DMX unit receives the DMX signal from a DMX console – where you can decide which color you want to pick and what luminous intensity you want for the whole LED strip. Therefore you have total control of every aspect of your installation!

 

 

Voltage

 

 

Usually, analog LED strips use 12V, 24V or 220V voltage. They are normally distributed in 5 meter rolls and use 60 LED diodes per meter (versions with less or more diodes per meter are of course available).

 

 

Usage

 

 

Typical usage of analog LED strips is for a home decorations, restaurants, bars, outdoor lightning, TV studios, shopping malls. Hence you can use the strip as a constant source of decoration light or as a background.

 

 

Examples of use Analog LED Strips

Analog strip with fits perfectly into variety of different places and installations where you need a single color line as a decorative source of light. From left top clockwise: examples showing two different sizes of TV studio with analog strips; analog LED strip as a decorative light on a building; and a mood creating back light in a bar

 

It is also worth noting that you can get a limited number of colors from an analog strip. More in the video below: 

 

 

 

Digital LED Strips

 

 

Digital LED strips are also called video, dream, pixel or addressable LED strips. All of them belong to the same category. 

 

 

Color change

 

 

The main benefit comparing to analog LED strips is that you can control every single LED diode (nice article) separately (hence addressable LED strip), creating various colours in different sections of one LED strip.

 

This allows you to use digital LED strips to display even videos. It is achieved thanks to additional chips (IC) directly inside the LED diode or on the digital strip board.

Simple effect that shows the main advantage of digital strip – different colors on a single strip.

 

 

Control system

 

 

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 (a short overview what is ArtNet, recommended!), live video stream or SD card as a video source.

 

 

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

 

 

Now, pay attention, as it gets a bit tricky with digital LED strips SPI communication – there is not only one standard! There are many control IC chips and every one of them uses a 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.

 

 

Control options 

 

 

LSS scheme of use

LSS 3 allows you to send signal through output using 4 independent SPI outputs. Each one of them can control up to 1024 LEDs. And that is a huge difference!

 

 

 

Typically, the SPI controllers receive video information over Ethernet cables from computer software or Art-Net. Some controllers can play video content from SD-card or stream live video (e.g. grabbing display through HDMI).

 

 

Why start using LED Strip Studio Controllers?

 

 

 

We are offering you great LED Controllers with long tradition, made in Europe and tested on hundreds of installations. LSS controllers are easy to use, have detailed documentation, strong customer support and own software solution. The technical details of LED controllers – LEC 3, SPI LED Controller, SPI Matrix, Powered LEC.

 

 

Voltage 

 

 

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

 

 

Usage

 

 

Digital LED strips can be used to achieve amazing animated light effects in club interiors, TV studios, TV shows and even on buildings. They can be used as decorations, but also for displaying video content for advertisement purposes. This larger spectrum of options allows you to be more flexible and innovative with your LED projects.

 

 

This is an example of what you can achieve with digital LED strips. A simple wall decoration pattern and a huge LED ceiling with video content “grabbed” through our LED Strip Studio software.

 

 

Recap of 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

    Hello

    My name is Adrian Chatellier , there are 5 years ago i had a costume project , i would like to become a WALL LED HUMAIN 🙂 ,
    Showtacle , LedStripStudio and their incredible technology help me to realise this project .
    With two Main Board , and two ethernet additional board , all pilot in Dmx , i can program and control 14996 leds in total ,
    Showtacle Technology and all their technician was allways listening and helping for find all solution and make work this nice project . Thank you so much
