There are digtal pixel led strip with Built-in IC in lamp !
Intelligent externally controlled LED light source integrating control circuit and light-emitting circuit.
LED lamp beads internal built-in control IC.Realizing single lamp bead programmable.Independent addressing control,
single point single control, breakpoint resumable transmission, point-by-point scanning, etc.
It can be used in LED full color lights with symphony marquee strips,pixel screens,transparent screens,LED light-emitting string lights,atmosphere design for car e-sports, smart speakers and other scenarios.
Symphony SK 6812 LED product introduction :
SK 6812 is a intelligent externally controlled LED light source that integrate control circuit and light-emitting circuit.Its appearance is as the same as 5050 LED lamp bead.Each element is a pixel point.The pixel point contains an intelligent digital interface data latch signal shaping amplifier drive circuit, a power supply voltage regulator circuit, a built-in constant current circuit, a high-precision RC oscillator, and the output drive adopts patented PWM technology,effective guarantee pixel point internal the color of light to be good consistency .
Data protocol adopts unipolar return-to-zero code communication method,after the pixel point is reset on power-on, the DIN terminal receives the date transmitted from the controller.The first 24bit data sent is extracted by each pixel point and sent to the inside of the pixel.The remaining data is reshaped and amplified by the internal reshaping processing circuit and then forwarded to the next cascaded pixel through the DO port.The signal is reduced by 24bit after the each pixel is transmitted each time.The pixel adopts automatic shaping and forwording technology,so that the cascaded pixel will not limited by signal transmission,and only limited by transmission speed requirements.
LED has the advantage of low voltage drive,environment production and energy saving,high brightless,large scattering angle , good consistency,ultra-low power,and long life,etc.Integrating control circuit on the LED makes the circuit simpler ,smaller in size,and easier to install.
Built-in IC-SK6812 lamp beads main application areas:
LED full-color luminous character string light, LED full-color module, LED symphony soft and hard light bar, LED guardrail tube, LED appearance/scene lighting.
LED point light source, LED pixel screen, LED special-shaped screen, various electronic products, electrical equipment marquee.
SK6812 lamp bead characterristic description ：
Top SMD integrates high-quality external control single-wire serial cascaded constant current IC
The control circuit and RGB chip are integrated in 5050 components,and it constitute a complete externalpixel point control,uniform color mixing and high consistency.
Built-in data reshaping circuit,any pixel point will be wave-shaped and than output after receiving the signal to ensure that the line waveform distortion will not increase.
Built-in power-on reset and power-down reset circuit,there will be no light when power on.
Grayscale adjustment circuit (256 levels of grayscale can be adjusted).
Red light drive special processing, more balanced color matching.
Single wire data transmission, unlimited cascading.
Reshaping and forwording enhanced technology,the transmission distance between two points exceeds 10M.
The date transmission frequency can reach 800kbps,When the refresh rate is less than 30 frames per second ,the number of cascades is not less than 1024 points.
Built-in power reverse connection production module,reverse power connection will not damage the IC.
