Final answer:
The back-up lighting used during power failures or other emergencies when normal systems are inoperative is often referred to as an Emergency Lighting System.
Step-by-step explanation:
The correct answer is option Computers and Technology.
The back-up lighting used during power failures or other emergencies when normal systems are inoperative is often referred to as an Emergency Lighting System. These systems are designed to provide illumination in the event of a power outage or other emergencies, ensuring that people can safely navigate and evacuate a building.
Emergency Lighting Systems typically consist of battery-operated lights that are connected to the main electrical supply through a charging circuit.
When the main power fails, the battery-powered lights automatically switch on, providing immediate lighting in the affected areas. Some Emergency Lighting Systems also include features such as exit signs and emergency exit route lighting to guide people towards the nearest exits.
The correct answer is that back-up lighting used during power failures or other emergencies when normal systems are inoperative is typically part of an emergency lighting system.
These systems are designed to be reliable and autonomous, providing illumination to allow safe evacuation and operation in times of need. It's noteworthy that a grid-tied solar power system usually does not function during power outages without a battery backup, due to safety concerns about energizing a disabled grid.
To ensure consistent lighting, it's essential to integrate a local energy storage system or have an alternative emergency lighting setup.
Advancements in lighting technology, such as the development of LED lighting, have greatly enhanced the capabilities and efficiency of emergency lighting systems.
LED lights require less power, have a longer lifespan, and are often used in modern emergency lighting fixtures. These innovations contribute to a safer and more secure environment during power outages or other disruptions.
