Study of the possibility of ensuring emergency lighting in installations operating in environments Ex

The use of electrical energy in potentially explosive atmospheres involves various particularities, fact for which there have been raised a lot of issues concerning the design, construction and exploitation of electrical equipment such as the signalling lighting or emergency lighting intended to be used in these atmospheres. Anti-panic lighting is a part of safety lighting which aims to avoid panic and to provide the lighting level which to ensure that people can reach the pathway from which they can identify the evacuation route. The current paper proposes the development of a device for ensuring anti-panic lighting for a limited period of time, which can operate on two wires, may be distance controlled and adaptable for lamps which operate in areas with explosion hazard (Ex areas).
