Lighting - A Life Saver
The laws in most countries make it an absolute requirement for all buildings
constructed to include emergency
There are plenty of regulations which have to be
adhered to, such as how many emergency light fittings should be installed, and when
emergency signs should be fitted.
All these regulations are there for valid
reasons, and correct placement and operation of emergency lighting systems can save countless
lives in dangerous situations such as a fire. When there is a sudden power failure, these
emergency light fittings switch on and guide people out of the building unharmed.
All emergency lighting is not the same. There are
small mobile lights which can be carried about, there are luminaires which are fitted with
emergency lighting components and won't switch on in emergency mode until there is a power
failure, and lastly there are emergency exit signs which are permanently switched
The laws and specifications for emergency
lighting vary from country to country. In the UK, emergency luminaires are manufactured to
function in emergency mode for 3 hours, but in Spain emergency lighting only has to operate
for 1 hour to meet requirements.
Lighting - The Different Types
Not only is there a difference between emergency
luminaires and emergency exit signs, but there are also different types of emergency
lighting. Apart from the obvious differences that spring to mind immediately such as lamp
types, light output and light distribution, there are also other options available to choose
from when designing your emergency lighting system.
Depending on the circumstances, light fittings could
have batteries fitted internally to provide power for emergency lighting as and when
required. Emergency light fittings could also be powered from a centrally housed battery
There are also different levels of emergency lighting,
in the sense that you could purchase the standard offering which is a light fitting which
provides an area with the required light during a power failure, a self test system which
does as the name suggests, or a Dali addressable system which can be controlled and tested
via Dali controls.
