A power supply system includes a storage battery, a console, a detector and an illumination device. The console is used to switch an operation of the power supply system at least from an on-grid operation to an off-grid operation. The detector is configure...

The system has an emergency light lamp (20) operated using a central control unit (2). The emergency light lamp is connected to an emergency light supply unit (4). A memory module (22) is connected with the emergency light lamp. The memory module is commun...

An illumination apparatus (10) includes a determination unit (14a) that determines whether or not the supply of power from the system power supply is performed. In addition, the illumination apparatus (10) includes a control unit (14b) that performs contro...

The operation control device (10) has a storage capacitor (36) for supplying the emergency light (43) with electrical power. A charging circuit (35) is connected to the storage capacitor through a converter (20) which is galvanic-separated to the mains vol...

The address data of lamps (4,5) are transmitted through a data connection line (3), and the flashing patterns are formed by the lamps based on the address data of lamps. The flashing patterns are made to differ depending on the respective address data of t...

An electronic fluorescent lamp ballast/choke is designed for a lamp's battery operation. For normal operation, an emergency lighting element has a digitally addressable control interface (DA-System) and a control output (LQ,DA-EVG) for the electronic fluor...

A group controller (9) coupled to the feeder lead of a lighting fixture (11) identifies a failure in power supply, and supplies a control signal to a emergency light fixture (7) which is switched ON by the received control signal. An independent claim is a...

Current interrupters (11), e.g. fuses are located between the power circuit change over switch (4) and the respective supply network (9, 10), especially its supply connections (5, 6;7, 8).
