Dimming signal converter with multi-signal input

Abstract

The invention discloses a dimming signal converter with multi-signal input. The dimming signal converter comprises a DMX input module, a DALI input module, a control module, an output module and a power supply module for supplying power; the input end of the DMX input module is used for receiving a DMX dimming signal, and the output end of the DMX input module is electrically connected with the control module; the input end of the DALI input module is used for receiving a DALI dimming signal, and the output end of the DALI input module is electrically connected with the control module; the input end of the output module is electrically connected with the control module, and the output end of the output module is used for being connected with an LED lamp; the power supply module is electrically connected with the DMX input module, the DALI input module, the control module and the output module. According to the invention, a DMX dimming control mode and a DALI dimming control mode are combined, and the application range of the product is expanded.

Description

technical field [0001] The invention relates to the technical field of LED dimmers, in particular to a multi-signal input dimming signal converter. Background technique [0002] With the gradual development of dimmable LEDs, there are many types of dimming signals, and the various signals are not compatible with each other. As long as a dimming signal is selected, it is necessary to use the light source driver corresponding to this signal control. . [0003] The current mainstream input control methods include DMX and DALI control methods. These two dimming systems have their own communication protocols, which can realize the transformation of various scenes, and address, timing, and storage of a single controlled light source driver. , It is convenient to use the computer console for precise control, which is more suitable for lighting scenes such as large shopping malls and large stages. [0004] The mainstream voltage output range is 0-10V, and the conventional output m...

AI Technical Summary

Problems solved by technology

[0005] The current problem is that the signal converters on the market are generally single-signal conversion, such as DMX control signal to 0-10V output or DALI control signal to 0-10V output, etc. Once a certain control signal input is selected, It cannot be compatible with another control signal input, which greatly reduces the applicability of the product
