A signal conversion control chip, method, and lighting control system. The chip is connected to an initial data stream through an input port, and the serial interface circuit performs discrimination and shaping to output, and then the data decoding circuit collects the initial data stream in a preset order. The code element signal of preset length; the format transcoding circuit reads the code element signal and generates the corresponding power signal, and the power signal is output to the LED drive control chip through the output port to complete the drive control; the communication port outputs to the next level of conversion control chip for serial communication. By receiving the initial data stream output by the main controller, and converting the power signal according to the initial data stream, each signal conversion control chip can control a preset number of LED drive control chips, and the single-line serial communication between the signal conversion control chips, The initial data flow output by a main controller can control the work of multiple signal conversion control chips, which reduces the number of main controllers and maintains a high screen refresh rate.
Description
technical field [0001] The present application belongs to the technical field of lighting control, and in particular relates to a signal conversion control chip, method and lighting control system. Background technique [0002] As the application fields of LEDs (Light Emitting Diodes, light emitting diodes) continue to expand, the demand for LED drive control chips is also increasing. The LED drive control chips perform data transmission on their power supply terminals, and the transmission speed is slow. At present, most of the LED drive control chips on the market are used in small-scale LED lamp groups. The traditional lighting control technology is to directly connect and control multiple LED drive control chips through a main controller. However, since the LED driver control chip uses the power line to transmit data, the data transmission rate is limited under the premise that the power line is greatly disturbed by itself. , there is a higher requirement on the picture...
