Emergency lamp of inconsistent action

Emergency lamp of inconsistent action
Emergency lamps are indispensable assistants in case of sudden disconnection of electricity. They provide safe lighting, allowing us to navigate in the dark and prevent possible injuries. But not all emergency lamps work the same way. Today we will talk about the lamps of inconsistent action - their features, pluses and minuses.
The principle of operation and device
These lamps, unlike constantly charged models, are turned on only when the main power is turned off. They do not have a built -in battery that would continuously support the work. Instead, they use a reserve power system that activates with power supply problems. As a backup source, for example, an electrochemical source can be used, which, due to certain reactions, allows you to produce electrical energy. This allows you to save space and, in certain cases, the cost of the device itself.
Pros of use of emergency shallow lamps
The main plus is an affordable price. An inconsistent action leads to saving on components, which, for example, provide maintaining a constant charge of the battery. Such a lamp is also more compact and light, which is important for installation in a limited space. Devices of this type are suitable for temporary lighting, where long -term work is not required from an emergency source.
Cons and restrictions on use
The main disadvantage is that the lamp will not provide lighting until the reserve system is triggered. This time can be sufficient in rooms with a short voltage drop. But in the case of a long shutdown, for example, in case of an accident on the power line, lighting may not be enough. Also, these lamps are not suitable for areas with high requirements for continuous lighting, such as hospital or data processing centers. The temporary interval of the operation and the working hours are limited. It is necessary to remember these factors when choosing and using this type of lamps.
