Abstract
The emergency lighting system (ELS) is mandatory to be installed at the commercial, residential, and public buildings and must be activated automatically in the case of disasters such as fire, earthquake, flood, hurricane, and electricity power outage situations. Conventional ELS must use an extra phase line to charge its battery as well as to detect the presence of an emergency condition. It is costly to use an additional phase line in the electrical system and requires a new system configuration in the existing systems. In this study, an ELS design is proposed that eliminates the need for additional phase line installation by using power line communication (PLC) circuitry. Additionally, LED lamp is preferred instead of fluorescent lamp due to their advantages. The proposed ELS detects the presence of emergency and power outage conditions and then charges the battery of the system through the PLC.
