Problems solved by technology

However, most of the products on the market currently only have a single color adjustment temperature or color adjustment, and a single interface. There are very few products compatible with the RDM512 protocol. The dimming curve cannot be adjusted by itself. Many, high cost and unsightly, it is impossible to adjust the position after decoration and installation, so it cannot meet the diverse needs of customers
Moreover, most of the products on the market cannot be upgraded online, which cannot meet the later application upgrades, making the application range very narrow

Abstract

The invention relates to the technical field of lamp control circuits, in particular to a DMX composite dimming circuit system, which comprises a central processing unit, a power supply circuit, a DMX TERMINAL interface, a DMX XLR male and female interface, a DMX RJ45 interface, an RS485 controller, an RS-485 conversion circuit, three input and output wiring ports and three level conversion circuits, wherein the central processing unit is connected with RGBWW and CCT toggle selection switches. Aiming at the problems in the prior art, the invention provides the DMX composite dimming circuit system which is convenient for a customer to use DMX controllers with different interfaces for control; on-line switching of CCT and RGBWW can be carried out by means of the DMX composite dimming circuit system, a user can use the color temperature adjusting function, the color temperature adjusting function can further be switched to the RGBWW different-color dimming function, and meanwhile light brightness adjustment can be achieved under the two functions.

Description

technical field [0001] The invention relates to the technical field of lamp control circuits, in particular to a DMX composite dimming circuit system. Background technique [0002] At present, the demand for LED lighting products is becoming more and more widespread, especially LED lighting has replaced the use of traditional lighting products. With the wide application of people, there are different lighting requirements for different scenes, especially people's demand for color temperature and RGBWW color adjustment. Applications in different environments. However, most of the products on the market currently only have a single color adjustment temperature or color adjustment, and a single interface. There are very few products compatible with the RDM512 protocol. The dimming curve cannot be adjusted by itself. Many, high cost and unsightly, the position cannot be adjusted after decoration and installation, and it cannot meet the diverse needs of customers. Moreover, mos...
