5050 Built-in IC multi-color intelligent control SMD LED light source
·This is an intelligent controlled LED light source that integrates a control circuit and a light-emitting circuit. Its appearance is the same as a 5050 SMD LED, and each element is a pixel. The pixel 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 to effectively ensure the color consistency of the pixel light.
·The data protocol adopts a unipolar return-to-zero code communication method. After the pixel is power-on reset, the DIN terminal accepts the data transmitted from the controller. The first 24 bit data sent is extracted by the first pixel and sent to the pixel point the internal data latch, the remaining data is reshaped and amplified by the internal shaping processing circuit and then forward to the next cascaded pixel through the D0 port. After each pixel is transmitted, the signal is reduced by 24 bits.
·LED has the advantages of low voltage drive, environmental protection and energy saving, high brightness, large scattering angle, good consistency, ultra-low power, and ultra-long life. Integrating the control circuit on the LED makes the circuit simpler, smaller in size, and easier to install.
·LED has integrated high-quality external control single-wire serial cascaded constant current IC
·The control circuit and chip are integrated in the SMD 5050 components to form a complete external control pixel, with uniform effect and high consistency;
·Built-in data shaping circuit and pixel receives the signal after waveform shaping and then output, to ensure that the wire waveform distorting will not accumulate;
·Built-in power-on reset and power-off reset circuit, light is not on when power on by default.
·Gray adjustment circuit (256 levels of gray can be adjusted).
·Special processing for red light drive, more balanced color matching
·Single-wire data transmission, unlimited cascading.
·Reshaping and forwarding enhanced technology, the transmission distance between two points exceeds 10M.
·The data transmission frequency can reach 800Kbps.When the refresh rate is 30 frames per second, the number of cascades is not less than 1024 points.
·LED full-color luminous character string light, LED full-color module, LED symphony soft and hard light bar, LED guardrail tube, and LED appearance/scene lighting.
·LED point light source, LED pixel screen, LED special-shaped screen, various electronic products, and electrical equipment marquee.
