1. Product Overview :
SK6813HV-09-6P-000 is a smart LED control circuit and light emitting circuit in one controlled LED source, which has
the shape of a 5050 LED chip. Each lighting element is a pixel, and the intensities of the pixels are contained within the
intelligent digital interface input. The output is driven by patented PWM technology, which effectively guarantees high
consistency of the color of the pixels. The control circuit consists of a signal shaping amplification circuit, a built-in
constant current circuit, and a high precision RC oscillator.
The data protocol being used is unipolar RZ communication mode. The 24-bit data is transmitted from the controller to
DIN of the first element, and if it is accepted it is extracted pixel to pixel. After an internal data latch, the remaining data
is passed through the internal amplification circuit and sent out on the DO port to the remaining pixels. The pixel is reset
after the end of DIN. Using automatic shaping forwarding technology makes the number of cascaded pixels without
signal transmission only limited by signal transmission speed.
The LED has a low driving voltage (which allows for environmental protection and energy saving), high brightness,
scattering angle, good consistency, low power, and long life. The control circuit is integrated in the LED above.
2. Main Application Field:
● Full color LED string light, LED full color module, LED super hard and soft lights, LED guardrail tube, LED
appearance / scene lighting
● LED point light, LED pixel screen, LED shaped screen, a variety of electronic products, electrical equipment etc..
3. Description:
● Top SMD internal integrated high quality external control line serial cascade constant current IC;
● control circuit and the RGB chip in SMD 5050 components, to form a complete control of pixel, color mixing
uniformity and consistency;
