This product is a set of control circuit and lighting circuit in one of the smart external control LED light source. Each LED its original shape and a same 5050LED lamp beads, each element is a pixel. Pixels contained within an intelligent digital interface data latch signal shaping amplification driving circuit further includes a high-precision internal oscillator and programmable 12V high-voltage constant current control section, to ensure the effective pixel light color highly consistent.
NRZ data protocol uses a single line of communication, the pixels in POR, DI end receives the data transmitted from the controller, the first to send over the 24bit pixel data is extracted the first point, to the internal pixels data latch, the remaining data processing circuit through the internal plastic shaping amplified through the LED's DO output port begins forwarding to the next cascaded pixels, each pixel through a transmission, the signal reduction 24bit. Pixel using automatic forwarding shaping technology, making the number of pixels of the cascade unlimited signal transmission, the signal transmission speed is limited only by the requirements.
LED has a low voltage driving, high energy saving and environmental protection, brightness, scattering angle, consistency, low power, long life and other advantages.
V: pick DC5V
DI: Input data access
DO: Output data access
Single LED lights main features:
smart reverse protection, power supply reverse polarity will not damage the LED inside IC.
IC control circuit with a LED light source utility power.
control circuit and RGB chip in a 5050 package of components constituting a complete external control pixels.
built-in signal shaping circuit, any one pixel after receiving the signal through the waveform shaping and then output to ensure line waveform distortion will not accumulate.
Built-in power-on reset and brown-out reset circuit.
each pixel of the three primary colors to achieve 256 brightness display, complete 16777216 colors full true color display, scanning frequency of not less than 400Hz / s.
serial cascade interface, through a signal line finish receiving and decoding data.
transfer between any two points in the transmission distance of not more than 5 meters without any additional circuitry.
When the refresh rate of 30 frames / sec, the number of cascades of not less than 1024 points.
data transmission speeds of up to 800Kbps.
light color highly consistent, cost-effective.
