EMERGENCY LIGHT Meaning and
Definition
-
An emergency light refers to a portable lighting device specifically designed to provide illumination during times of emergency or power outages. It is intended to serve as a backup light source when the regular power supply is disrupted or unavailable.
Emergency lights are typically equipped with a rechargeable battery, allowing them to operate independently of the main electrical system. This feature ensures that the light continues to function even in situations where the power supply has been cut off. To indicate its readiness for use during an emergency, the device is often on standby mode, charging the battery and awaiting power failure detection.
The primary purpose of emergency lights is to provide emergency egress lighting, helping people to safely navigate their way out of a building or space during a crisis. They are commonly installed in various settings, including commercial buildings, educational institutions, hospitals, and residential areas. Most emergency lights are designed to automatically activate when the main power supply ceases, and they employ efficient lighting techniques such as LED (Light Emitting Diode) technology to ensure extended battery life and durability.
Emergency lights often feature high visibility colors, such as bright red or green, to enhance visual awareness and ensure the light source is easily distinguishable in times of emergency. They may also incorporate additional features like blinkers or sirens to attract attention or signal distress.
