The emergency bulb lamp is a safety lighting device composed of a spherical bulb and an internal battery. It is usually installed in public places such as emergency exits, corridors, elevator lobbies, parking lots, shopping malls, and homes as backup lighting equipment, used to provide a certain degree of lighting and safety protection for people in case of power outage or other emergency situations. Next, let's introduce the working principle of emergency bubble lights.

1. Charging

The emergency bubble light is equipped with a rechargeable battery inside, which will be charged through an AC power line during normal times. In an emergency state, when the main power supply fails, the battery will automatically switch to DC power mode to provide energy support for emergency lighting.

2. Emergency power start

When the main power supply fails or the power grid is cut off, the emergency bulb light will automatically switch to the built-in battery DC power mode to start the emergency power supply.

3. Emergency lights start working

When the emergency power supply is activated, the LED light inside the emergency bulb light will automatically light up. These LED lights can emit sufficient brightness to provide lighting support and help people maintain safety. The design of the bulb lamp, in order to avoid direct reflection of light on the eyes, has treated the lampshade to make the light softer.

4. Automatic shutdown

Emergency bubble lights usually have a certain service life and can also be automatically switched on and off through circuit control. When the battery is low or its lifespan expires, the bulb light will automatically turn off, providing users with a safer user experience.

Summary: The working principle of emergency bubble lights is the principle of charging, power switching, light operation, and automatic shutdown. In emergency situations, emergency bubble lights can provide lighting support and safety protection for people.
