DISTRIBUTED LIGHTING CONTROL SYSTEM

摘要

A lighting system (8) includes a plurality of control modules distributed on the AC power line for remote control of lights within a residential/office building structure. Each control module is hard-wired to an electrical load and is provided with a dimmer (28) and up to four control switches and LEDs (42) for status indication. Each control module (10) has a data decoder (20) , a switch and LED interface (24), a dimmer driver (22) and processor (16) wit h memory (18) for independently processing and communicating data signals to t he other control modules on the AC power line without the need for a central processor to coordinate the lighting control operation. Every control module is programmable through a programmable module and a PC. The system data downloaded to each control module includes a unique address, a system configuration file and a response file for evaluating system transmission commands. Each control switch may be programmed to control the hardwire load or any other load in the system.
