What is WS2813 addressable LED strip light?

WS2813 is an intelligent externally controlled LED light source integrating a control circuit and a light-emitting circuit. Encapsulated pixel IC in SMD5050 component, the pixel contains an intelligent digital interface, data latch, signal shaping amplifier drive circuit, anti-reverse circuit, and also contains a high-precision internal oscillator and a high-precision constant current control module; realizes dual-channel signals Transmission, when a single pixel is damaged, it does not affect the overall color display.

The data protocol adopts a single-wire return-to-zero code communication method. After the pixel is powered on and reset, the DIN terminal accepts the data transmitted from the controller. After the 24Bit data is extracted by the first pixel, it is stored in the internal data latch, the remaining data is transmitted from the DO port to the next pixel through the internal shaping processing circuit, the number of cascaded pixels is only limited by the transmission speed; the BIN or DIN terminal receives data and transmits the signal,  the dual data interface ensures that the damage of a single IC does not affect the cascading transmission of the signal, and the control IC remains in the receiving state of the BIN port until the next power-on reconfirmation after power failure.

Port scanning frequency up to 2KHZ, no flicker phenomenon, can achieve 256 levels of glow display, LED strip light work with Raspberrypi/Arduino UNO development board or dream color LED controller, with 16 million dynamic color chasing effects; WS2813 addressable LED strip, supports DC5V Low voltage input, single LED cuttable, individually addressable, with high value for money. The length and waterproof level of the LED strip can be customized.

How do WS2815 addressable LED strip lights work?

To ensure that the pixel point in the long-distance transmission to achieve good consistency of mix light, the WS2815 LED integrates the IC and control circuit in the SMD5050 package, IC internal contains intelligent digital interface data latching signal shaping amplification driver circuit, high-precision internal oscillator and high-precision constant current control module. to ensure the consistency of pixel colors; dual channels Signal transmission, when a single pixel is damaged, does not affect the overall color display.

The data protocol adopts a single-wire return-to-zero code communication method. After the pixel is powered on and reset, the DIN port accepts the data and stores it in the internal data latch, the remaining data is transmitted to the next pixel through the automatic shaping and forwarding technology, and the pixels are cascaded, the number of pixels in cascade is only limited by the requirement of the signal transmission element. The BIN or DIN terminal accepts data and transmits signals, if there is no signal at the DIN terminal and there is a signal at the BIN terminal, switch to the BIN terminal to input and output signals. The damage of a single IC will not affect the cascade transmission of the signal (two adjacent ICs are damaged, then the entire LED strip is off).

Why so many customers choose WS2815 addressable LED strip light?

What is the different between WS2811 and WS2818?

WS2818 is an upgraded version of WS2811, it is a 3-channel LED drive control dedicated circuit, internal LED chip contains a smart digital interface data latch signal shaping amplifier drive circuit, high-precision internal oscillator, 12V high-voltage programmable constant current output driver and high-precision constant current control module; dual-channel signal transmission, single-chip damage does not affect the overall display effect (except for damage to two adjacent chips), supports DC12V low voltage input, 3 LEDs cuttable(one IC controls 3 LEDs); external IC.

The data protocol uses a single-wire return-to-zero code communication method. After the chip is powered on and reset, the DIN terminal receives the data and stores it in the data latch inside the chip, the remaining data is reshaped and amplified by the internal reshaping processing circuit and forwarded to the next pixel, the number of cascaded pixels is only limited by the signal transmission speed requirement, when using the BIN side as the control signal receiving port, the control data of the BIN port is 24 bits more than the control data of the DIN port, so as to ensure that the number of points controlled by the two methods is consistent.

Before the DIN terminal inputs, the RESET signal, the OUTR, OUTG, and OUTB control terminals generate different duty cycle control signals, keep the source output unchanged, and receive new data after receiving the RESET signal, and forward the data to the next pixel through the DO port, when receiving a low-level RESET code above 280us, the chip outputs 24bit PWM data pulse width to the OUTR, OUTG, and OUTB pins.

How does TM1914 LED strip light work?

TM1914 is a 3-channel (OUTR/OUTG/OUTB) LED constant-current driver dedicated circuit, internal LED chip integrates MCU single-wire dual-channel digital interface, data latch, LED constant current drive, PWM brightness control and other circuits, which can switch input to each other through a dual-channel digital interface (DIN, FDIN) and cascade with DO port so that the external controller can control the chip with only a single wire. 

The chip is a single-wire dual-channel communication mode, using the normalization code to send signals, the DIN port selects to access data, the mode is set to 48Bit, where the first 24Bit is the command code, and the last 24Bit is the inspection inverse code; the whole process is the chip on the complex potential to receive data, data received by the DIN and FDIN port, D01/D02 port forwarding to provide display data for the next cascade chip. Before forwarding the data, D01/D02 port always shows a high level. Before the chip receives the Reset signal, the original output of OUTR/OUTG/OUTB remains unchanged; after receiving the Reset signal, it outputs the PWM waveform of the corresponding duty cycle, and the chip waits to receive new data again.

Built-in RC oscillator and clock synchronization according to the online signal, data regenerative transmission to the lower level, the signal does not become distorted as the cascade becomes farther; single-wire dual-channel interface, DIN and FDIN dual-input interface, D01/D02 dual output interface, the signal does not affect the normal operation of other chips due to the abnormality of a chip (except for the abnormality of two adjacent chips)
