What is WS2811 Addressable RGB LED Strip?
• WS2811 Working Principle
The WS2811 is 3 output channels special for LED driver circuit. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit.Also include a precision internal oscillator and a 12V voltage programmable constant current output drive. In the purpose of reduce power supply ripple, the 3 outp- ut channels designed to delay turn-on function.
IC use single NZR communication mode.After the chip power-on reset, the DIN port receivedata from controller, the first IC collect initial 24bit data then sent to the internal data latch, theother data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade IC through the DO port. After transmission for each chip,the signal to reduce 24bit. IC adopt auto reshaping transmit technology, making the chip cascade number is not limited the signal transmission, only depend on the speed of signal transmission.
The data latch of IC depend on the received 24bit data produce different duty ratio signal at OUTR, OUTG, OUTB port. All chip synchronous send the received data to each segment when the DIN port input a reset signal. It will receive new data again After the reset signal finished. Before a new reset signal received, the control signal of OUTR ,OUTG, OUTB port unchanged. IC sent PWM data that received justly to OUTR, OUTG, OUTB port, after receive a low voltage reset signal the time retain over 50us. We offer two package SOP8 and DIP8.
• Is WS2811 individually addressable?
No, the WS2811 LED driver does not support individually addressable. The WS2811 is a popular external IC used for controlling addressable RGB LEDs, similar to the popular SM16703, RGB LED. Each WS2811 chip can control a group of RGB LEDs and can be programmed to set the color and brightness of that pixel independently of any other pixels in the chain. By chaining multiple WS2811 chips together, it is possible to control entire arrays of RGB LEDs with complex patterns and animations.
Pros & Cons of WS2811 Addressable RGB LED Strip
• Advantages of WS2811 Addressable RGB LED Strip
There are several reasons why you may want to choose the WS2811 RGB LED strip for your lighting project:
- Addressable: The WS2811 LED strip is addressable, which means that each group of LEDs can be separately controlled. This allows for more intricate and complex lighting patterns and effects to be created.
- Wide range of colors: The WS2811 LED strip offers a wide range of colors, including red, green, blue, and all possible combinations of these colors. This allows you to create stunning visual displays that are sure to grab attention.
- Easy to use: The WS2811 LED strip is easy to use, even for beginners. It can be controlled with popular platforms like Arduino and Raspberry Pi, and there are plenty of resources and tutorials available online to help you get started.
- Flexible and adaptable: The WS2811 LED strip is flexible and can be bent to fit a variety of shapes and surfaces. This makes it perfect for use in a wide range of applications, including accent lighting and decorative lighting.
Overall, the WS2811 addressable RGB LED strip is a versatile and reliable lighting solution that offers a wide range of benefits for various applications. Whether you’re looking to create a dynamic visual display, add some accent lighting to your home or office, or create a unique lighting installation for an event or performance, the WS2811 LED strip is a great choice.
• What is the Limit of WS2811 Addressable RGB LED Strip?
The WS2811 has certain limits that should be taken into consideration when designing an LED lighting system. Some of the key limits of the WS2811 IC include:
- Maximum Current: The WS2811 can handle a maximum current of 18mA per channel (red, green, and blue). Exceeding this limit can damage the IC or the LEDs.
- Data Rate: The WS2811 has a maximum data rate of 800 kilobits per second (kbps). This means that it can control up to 400 RGB LEDs at a refresh rate of 30 frames per second.
- Signal Integrity: The WS2811 is sensitive to noise and signal degradation. Proper signal conditioning and layout techniques should be used to ensure reliable operation.
It’s important to note that while the WS2811 has these limits, they are typically not a limiting factor for most LED lighting applications. However, for large-scale installations or complex systems, these limits may need to be taken into consideration during the design phase.
WS2811 vs WS2815, What is the Difference
WS2811 and WS2815 are both popular addressable LED driver ICs used in LED strips, matrices, and other LED lighting applications. While they have some similarities, there are also important differences between them.
• Voltage
The main difference between WS2811 and WS2815 is their voltage requirements. For the WS2811 and WS2815 LED strips on the market, WS2811 addressable RGB LED strips are usually DC12V and DC24V to be chosen, while WS2815 is designed to operate at only DC12V.
• Signal transmission
Another difference is the way they handle faulty LEDs. In WS2811, if one LED fails, it can cause the entire string of LEDs to stop working. WS2815, on the other hand, has a backup data line that can bypass the faulty LED, allowing the rest of the LEDs in the string to continue working.
• Price
Additionally, WS2815 is generally more expensive than WS2811 due to its higher voltage tolerance and backup data line feature.
In summary, while both WS2811 and WS2815 are popular addressable LED driver ICs, WS2815 has a backup data line to bypass faulty LEDs, and it is individually addressable, which makes it more reliable in certain applications, but also more expensive.
