LED industrial lighting wired remote multi-channel intelligent dimming control system

Abstract

The invention discloses an LED industrial lighting wired remote multi-channel intelligent dimming control system, and the system comprises a microcontroller module, a PWM duty ratio display module, atiming display module, a man-machine interface module, a PWM open-drain output module, a PWM optical coupler receiving module and a power adapter. The microcontroller module carries out intelligent conversion processing of the PWM data according to the instruction information sent by the man-machine interface module, and displays a PWM duty ratio value on the PWM duty ratio display module; and meanwhile, according to a PWM duty ratio and a control instruction, the PWM on-off output module and the PWM optical coupler receiving module control a plurality of LED driving power supplies contained in the PWM optical coupler receiving module, so that dimming or lamp turning-off of a plurality of LED lamps is realized. The system has the advantages that the remote transmission of PWM signals is reliable and stable; the system is not affected by interference, and the lamp coverage is wide; the dimming and turn-off of the multi-channel dimming turn-off control system are achieved in an intelligent digital control mode, and the multi-channel dimming turn-off control system can meet and be suitable for the industrial or commercial intelligent energy-saving lighting requirements.

Description

technical field [0001] The system belongs to the field of LED lighting, and in particular relates to a wired remote multi-channel intelligent dimming control system for LED industrial lighting. Background technique [0002] LED lighting technology has developed from landscape lighting and road lighting to interior decoration lighting, commercial lighting and industrial lighting of civil buildings. At the same time, wireless technologies such as zigbee and Z-wave are becoming more and more common in smart home lighting. However, there are relatively few product technologies in terms of industrial lighting intelligence. [0003] The industrial lighting environment is relatively harsh. For example, the height and spacing of various machinery and equipment are different, and various factors such as the steel structure of the ceiling chandelier environment and unstable temperature and humidity are not easy to install wireless intelligent control equipment.

AI Technical Summary

Problems solved by technology

For example, the height and interval of various machinery and equipment are different, and various factors such as ceiling chandelier environment steel structure and unstable temperature and humidity are not easy to install wireless intelligent control equipment.

[0004] Especially in the industrial environment, the lighting wireless control signal is easily affected by the interference of objects during transmission, and the signal attenuation is also large, which cannot make the wireless control equipment operate normally.
