There are several types of emergency lights and different ways of using them: it all depends on the environment or the turning of the place. But for practical purposes we can segment them into three groups:
This is called when there is a failure in the supply of normal lighting or an inadequate level of it, which prevents to continue with the normal activities of the place. These lights do not have a duration of determined use, because in normal conditions can be used the necessary time until the conclusion of daily activities.
Is a luminaire that is expected to be used in the event of failure of the main lighting. This provides the possibility of continuing with normal activities to complete them until the supply is restored, or until evacuation is made in the event of an emergency. In this category we could also add lighting for risk areas, which has to do with workplaces with high risk of accidents. Their duration may be minimal or sufficient to interrupt activities safely.
This is called a part of the emergency lighting that allows the evacuation of a place. This allows us to recognize alternate exit routes, identify meeting points, locate fire-fighting tools, medicine cabinets and other useful tools in contingencies. Lighting layout
It is important to have prior knowledge for the proper location and installation of emergency lights. For this it is necessary to plan a layout of the lighting, depending on the space that needs to be illuminated.
The importance of the layout lies in making visible the lamps with the information of their nominal voltage or their range of operating voltages. It is also essential to ensure that the batteries used are always loaded with the necessary load so that the user can find the greatest possible protection and safety.
Places where emergency lighting is required include hospitals, offices, hotels, industries, restaurants and entertainment venues. However, it should also be mandatory in residential buildings, schools, as well as in our own homes. Particular attention should be paid to leaving light signs on the evacuation routes in accordance with the Law .
