1. Product Overview :
SK6805D-EC4228 is a smart LED control circuit and light emitting circuit in one
controlled LED source, which has the shape of a 4228 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:
