Emergency lighting system has energy conversion device which generates compressed air in normal operation with electric current and stores compressed air in reservoir, and generates electric power in emergency mode from compressed air

摘要

The system has an emergency light (10) which is connected to the energy storage device (14). The energy storage device has a compressed air reservoir (5) connected to energy conversion device (13). The energy conversion device generates compressed air in normal operation with the electric current and stores compressed air in compressed air reservoir, and generates electric power in emergency mode from compressed air stored in reservoir. A control device (9) detects failure of power source, and performs restoration of power source in control mode in case of failure of power source.
