Product description
ntelligent external control LED light source that integrates control circuit and light-emitting circuit. Its appearance is the same as a 5050 LED lamp bead, each element is a pixel. The pixel contains a smart digital interface data latch signal shaping amplifier driving circuit, and also contains a high-precision internal oscillator and a 12V high-voltage programmable constant current control section, which effectively ensures that the color of the pixel light is highly consistent.
The data protocol uses a single-line zero-code communication method. After the pixels are reset after power-on, the DIN end accepts the data transmitted from the controller. The 24bit data sent first is extracted by the first pixel and sent to the pixel. Data latch, the remaining data is reshaped and amplified by the internal shaping processing circuit and then forwarded to the next cascaded pixel point through the DO port. After each pixel point is transmitted, the signal is reduced by 24bit. The pixel adopts the automatic shaping and forwarding technology, so that the number of cascades of the pixel is not limited by the signal transmission, only the signal transmission speed requirement is limited.
LED has the advantages of low voltage driving, environmental protection and energy saving, high brightness, large scattering angle, good consistency, ultra low power, and long life. Integrating the control circuit on the LED makes the circuit simpler, smaller, and easier to install.
