What is an Addressable LED Strip?

Our strips that light with IC are collectively referred to as addressable LED strips. Many English names include addressable LED strips, digital LED strips, and LED pixel strips. The significant similarity has light effects like chasing, flowing water, magic color, etc. The most important advantage of using addressable LED strip lights is that they allow the active control of signal transmission speeds and produce gray levels of each RGB or RGBW lamp bead using IC to achieve a full-color spectrum effect. Only addressable LED strips can get different colors from every individual light bead. We refer to this as “getting the full color.”

Classification of Addressable LED Strips:

There are two addressable LED strips according to IC - built-in IC and external IC strips. These models include:

Built-in IC:

WS2812B,WS2813,WS2815,SK6812,SK6813,SK9822,P943,P9423F,P9411,APA102,APA104,GS8812,HD107, HD108, and more

External IC: 

WS2801, WS2821, WS2811, LPD8806, TM1803, TM1804, DMX512, UCS512, UCS1903, and more.

You can see an example of the differences between these two forms below.

You can also divide these addressable LED strips according to different voltages: 

5V, 12V, 24V versions are possible, with 12V and 24V being divided into single-point, single-control. Single point single control means that each lamp bead on the strip can be controlled. For example, if 1-IC has multiple lamps, then 1-IC controls 3 lamps or 1-IC controls 6 lamps. A more comprehensive visual explanation can be found at this link: https://rolllights.com/voltage-variation.

Addressable LED strips divided by color: 

  • White, RGB, and RGBW - all ICs can create an RGB spectrum.
  • The ICs that may do RGBW include SK6812, P9412, and DMX512.
  • For white light, the WS2811 IC is generally utilized.

Addressable LED Strips divided by SMD quantity: 

  • 30 LED/m,32 LED/m,40 LED/m,48 LED/m
  • 60 LED/m,72 LED/m,144 LED/m

Addressable LED Strips divided by type of SMD:

  • Most magic strips utilize 5050 SMD.
  • In some size requirement cases, the magic light strips will use 3528SMD.
  • We also provide 020 SMD for side review strips.

Addressable LED strips divided according to the signal: 

In general, addressable LED strips use SPI and DMX signal strips. All use SPI signals except for the DMX512.

 

Addressable LED Strips are Mainly Used in

The LED strip is highly versatile, making it a popular choice for residential, business, and commercial use. The FPC material is soft, allowing it to be bent, folded, and rolled at will. It can be easily moved and stretched in many ways without fear of breaking. This will enable consumers to get the full effect of chasing, flowing water, magic color, and other desired display forms.

With excellent flexibility, brightness, color, and variability, addressable LED strips have become the premier choice for personal DIY home decor, shop windows, fashion shows, display screens, advertising signs, etc.

What is the Difference Between Different ICs?

The primary difference between ICs relies on the type of product. For example, the SK series is a manufacturer, while APA, WS, and P are code names of different packaging manufacturers. There are also differences in the same series. Consider the SK series:

  • The SK6812 5V is a single-point single-control, but it is not a breakpoint light resume function.
  • The SK6813 has the function of resuming transmission after a breakpoint.
  • SK6812 can do RGB and RGBW, but SK6813 cannot use RGBW.
  • SK6812 has a mini version (3535) with a 4mm or 5mm board width.
  • HD107/HD108 uses two-wire transmission channels to replace the APA102.

The following table provides a more visual comparison of the differences between ICs.

The waterproof method for an addressable LED strip:

The following is the process for making an addressable LED strip waterproof.

  1. Non-waterproof addressable strips:stick removable 3M glue on the back.
  2. Waterproof IP65:Epoxy glue is waterproof with removable 3M glue on the back.
  3. Waterproof IP67:The entire casing is waterproof with 3-5 buckles per meter, and there is no removable 3M glue on the back.
  4. Waterproof IP68:The silicone half-sleeve is waterproof with 3-5 snaps per meter, and there is no removable 3M glue on the back.

The waterproof form of the addressable LED strip is similar to our regular strips. For details, please take a look at this link:https://rolllights.com/waterproof-led-strip.

LEDWorker Lighting Features of Conventional Addressable Strips

The number of LED lamps depends on the product designer or user performance requirements. However, it is generally an even number of instances. In addition, the LED addressable strip has two other key parameters: signal transmission speed and product gray level. These two parameters directly affect the display of products.

WS2812B 5050RGB Addressable Strips:

This is a single-point single-control, built-in chip which integrates the main part of the driver IC into the commonly used 5050RGB SMD lamp beads. The advantage is that the circuit is integrated into the lamp bead, allowing you to omit the external circuit. This reduces the circuit design, external components, volume, failure rate, and production cost of programmable lamps.

This innovation can be used with most controllers and has the advantages of convenient programming, high lamp brightness, energy savings, and extended service life. It is suitable for making LED displays, advertising boards, KTV, bar lighting decoration, and more.

The product can control the display of the built-in IC lamp beads through a signal line and two power lines to achieve effects like text, pictures, and animation. The WS2812B magic light strip can display different colors in segments, while the 5050RGB light strip displays only the same color. You can learn more by watching this YouTube video.

The effects are possible thanks to the single-point single-control function of the 2812 light strip and can be easily extended by tandem construction. One signal line can control up to 500 LEDs with a 30hz refresh rate.

 

Features:

  1. The conventional length is 5 meters/roll, which can be cut by each group.
  2. The luminous color is pure, soft, and gorgeous. You also get unique color options such as full color, colorful, positive white, warm white, and cool white.

WS2811 Control IC Features & Performance: 

This product uses 1-IC with 3 lights, commonly known as “one-for-three.” The IC is WS2811, and the LED decoration IC is used for single-point control. Epistar 5050RGB SMD lamp beads are used, and the working voltage is 12DC.

Equipped with a 12V full-color controller, this can realize effects like gradient, jump changes, single/multi8pe horse racing change, flowing water, chasing, meteor/flash monochromatic change, mixing change, etc.

The light strip has an intelligent IC core that can be programmed through a full-color controller to achieve any desired effect. The mounting is unique for the FPCB (flexible circuit board) to allow folding resistance and waterproof level reaching IP68. The low-voltage DC power supply is safe and convenient, offering various luminous and gorgeous colors.

  2. Using SOP8 package pins, the fixed output current of the RGB channel is 15.5mA-17.5mA.
  3. When making a flexible light strip, it needs a DC12V power supply to design an IC that controls 3 lamp beads to emit light. If a DC24V power supply is required, an IC is designed to control 6 lamp beads to emit light.

DMX512 External 5050RGB Addressable Strips:

DMX is the abbreviation of Digital MulTlpeX, which means multiple digital transmission. The DMX 512 control protocol is an industry standard for data transmission between lighting controllers and lighting equipment released by the United States Stage Lighting Association (USITT) in 1990. The full name is USITT DMX 512 (1990).

Currently, based on the DMX512 control protocol, there are only integrated SOP8/SOP10/SOP16 pin external ICs, and the circuit function design of each manufacturer is similar.

DMX512 products have the function of continuous transmission after the breakpoint. They are widely used in the fields of outdoor lighting and engineering.

Its control protocol has a wide range of general applications and benefits, including good software compatibility, strong anti-wave frequency interference ability, high Voltage transmission, and simple installation and wiring.

In addition, it can be combined with SPI serial and parallel applications, supports wiring address code, and has high flexibility and adjustability. It can also address feedback function, which can detect bad pixel issues on the software side.

Compared with SPI products, DMX512 has higher costs, and the signal transmission and PWM refresh speeds are slower.
