AI Technical Summary

Technical Problem

In current DMX512 applications, most LEDs in DC24V applications are divided into 6 or 7 pixels, which results in poor aesthetics and affects the lighting display effect.

Method used

The system employs a DMX512 protocol conversion module, which includes a DMX512 input module, a DMX512 transmission module, a DC-DC step-down module, a DMX512 to SPI converter module, an SPI transmission module, and an SPI scanning module. The DMX512 to SPI converter module converts the signal into an SPI signal, and the SPI scanning module detects the actual address consumed to prevent address loss and code errors, thus enabling single-lamp single-control.

Benefits of technology

It improves the display detail and color rendering flexibility of the lighting fixtures, ensures stable system operation, and prevents address loss and errors.

Abstract

The application provides a DMX512 protocol conversion system, method and lamp, and belongs to the technical field of LED lamps. The DMX512 protocol conversion system comprises a DMX512 input module, a DMX512 transmission module, a DC-DC voltage reduction module, a DMX512 to SPI module, an SPI transmission module and an SPI scanning point module. The DMX512 input module is connected with the DMX512 transmission module and the DMX512 to SPI module respectively. The DMX512 transmission module is connected with the DMX512 to SPI module. The SPI transmission module is connected with the DMX512 to SPI module. The SPI scanning point module is connected with the DMX512 to SPI module and the SPI transmission module respectively. The DC-DC voltage reduction module is connected with the DMX512 to SPI module. On the basis of reserving the DMX512 control protocol on the brightening lamp, the DMX512 signal is converted into an SPI signal through the DMX512 to SPI module, the lamp is controlled through the SPI signal, the effect of single lamp control is achieved, and the display effect of the lamp is more delicate.
