Intelligent external control integrated LED light source
Product overview:
SK6812MINI is a set of control circuit and light-emitting circuit in one of the intelligent control LED
Light source. The appearance of a 3535LED lamp, each element is a pixel.
The digital interface of the pixel is contained in the data of the intelligent digital interface,
Power supply voltage circuit, constant current circuit, high precision RC oscillator, the output driver uses a special
Lee PWM technology, effectively ensuring the color of the pixels within the high consistency of light.
The data protocol is based on the method of single polarity return to zero code, and the pixel points are reset after power up,
DIN terminal to receive data from the controller to transmit, first sent to the 24bit data is the first
After a pixel point is extracted, the data latch is sent to the pixel point, and the remaining data are left.
After the internal plastic and plastic processing circuit, the chip is transmitted through the DO port to the next.
The transmission of a cascade of pixels, each of which passes through a pixel, reduces 24bit. Pixel point
The use of automatic plastic forwarding technology, so that the number of pixels in the pixel point is not limited to the transmission of signal
System, only limited signal transmission speed requirements.
LED has low voltage drive, environmental protection and energy saving, high brightness, large scattering angle, good agreement,
Ultra low power, long life, etc.. The control circuit is integrated with the LED, the circuit is changed.
More simple, small size, easy to install.
Major application areas:
The full-color LED string light, LED full color module, LED super hard and soft lights, LED guardrail
Tube, LED appearance / scene lighting
The LED point source, LED pixel screen, LED shaped screen, a variety of electronic products, electrical equipment run
Lantern, model.
