Abstract
Disclosed is a light intensity signal transmitting device based on a high-speed LED array. The light intensity signal transmitting device includes an LED array and a control board card; through a novel arrangement and driving mode, the LED array has a high-speed modulation characteristic and can transmit high-bit light intensity information at the switching speed of single-point LEDs; the control board card performs high-speed display by gating an I/O port of the LED array, and is used as a light intensity signal transmitting end to transmit a light signal. According to the light intensity signal transmitting device, on the premise that the switching rate of the LED array is ensured, multi-bit binary data transmission is realized, and the transmission rate is improved.
