Dynamic SK6812 LED light product overview:
SK6812 is a smart external control LED light source that integrates control and illumination. Its appearance is the same as a SMD 5050 LED bead, and each component is a pixel. The pixel contains the intelligent digital interface data latch signal shaping amplifier driver, power regulator circuit, built-in constant current circuit, high-precision RC oscillator, and the output driver adopts patented PWM technology to effectively ensure the light in the pixel. High color consistency.
The data protocol adopts the uni-polar return code communication mode. After the power-on reset, the DIN terminal accepts the data transmitted from the controller. The first 24 bits of data are extracted by the pixel and sent to the pixel. The data latch of the part, the remaining data is subjected to internal shaping, and the data is amplified and then transmitted to the next cascaded pixel through the DO port. The signal is reduced by 24 bits after each pixel transmission. Pixels use automatic shaping and forwarding technology, so that the number of cascaded pixels is limited by the signal transmission, only limited signal transmission speed requirements.
LED has low voltage drive, environmental protection and energy saving, high density, large scattering angle, good consistency, ultra-low power, and long life. The control power is integrated on the LED, and the power becomes simple, small, and easy to install.
while SK6812 is 3 pin lamp, so it is not with back up signal. but SK6813, WS2813 led light with back up signal.
Built-in ic-sk6812 led beads mainly application:
● LED full color string, LED full color module, LED magic color flexible strip light , LED guardrail tube, LED pixel bar light.
● LED point light source, LED pixel screen, LED shaped screen, various electronic products, electrical equipment marquee.
SK6812 lamp bead features:
● Top SMD integrates high-quality external control single-wire serial cascade constant current IC;
● The control circuit and RGB chip are integrated in the SMD 5050 components to form a complete external control pixel. The color mixing effect is uniform and the consistency is high.
● Built-in data shaping circuit, after receiving any signal, any pixel will be waveform-shaped and then output to ensure that the line waveform distortion will not be accumulated.
● Built-in power-on reset and power-down reset circuit, the power is off;
● Gray scale adjustment circuit (256 levels of grayscale adjustable),
● Red light drive special treatment, the color matching is more balanced,
● Single-line data transmission, which can be cascaded indefinitely.
● Signal enhancement technology, the transmission distance between two points is more than 10M.
● The data transmission frequency can reach 800Kbps. When the refresh rate is 30 frames/second, the cascading number is less than 1024 points.
● Built-in power supply reverse connection protection module, reverse power connection will not damage the IC.
