Emergency Exit Light

Key Features:

1. Dual Power Source:

   • AC Power: During normal operation, the light is powered directly by the building’s electricity supply, ensuring continuous operation.
   • Rechargeable Battery: When the power goes out, the rechargeable battery automatically takes over to provide emergency illumination.

2. Automatic Switching:

   • Automatic Transfer: The light switches seamlessly between AC power and battery power without any manual intervention.
   • The transition from AC to battery power happens instantly when the power fails, ensuring no interruption in the illumination.

3. Battery Charging:

   • The internal rechargeable battery charges automatically when the light is connected to the AC power supply.
   • Typically uses lithium-ion, NiCad, or NiMH batteries for efficient energy storage and long-lasting use.
   • Battery typically provides 3-4 hours of backup power during an emergency.

4. Energy-Efficient LED Technology:

   • Most modern emergency exit lights use LED lights to ensure low power consumption and long life.
   • LED technology provides bright illumination while consuming minimal energy, making it ideal for both normal and emergency conditions.

5. Built-in Test Function:

   • Often comes with a test button to manually check if the light is operating properly on both AC power and battery power.
   • Regular testing helps ensure that the rechargeable battery is working and that the system is ready for emergencies.

6. Clear Exit Signage:

   • Includes exit signs (often with green LED lighting and directional arrows) to provide clear guidance to the nearest exit in case of an emergency.
   • The clear exit marking enhances visibility in low-light situations, ensuring safe evacuation.

7. Durable Construction:

   • Designed with impact-resistant enclosures to withstand damage in case of accidental bumps or falls.
   • Weatherproof options available for outdoor use or in harsh environments.

8. Compliance with Safety Standards:

   • Meets fire safety regulations and standards such as NFPA 101 (Life Safety Code), EN 60598, and UL 924, ensuring that the system is reliable and legally compliant.

Applications:

• Commercial and Office Buildings: To ensure that employees and visitors can safely exit the building during a fire or power outage.
• Residential Buildings: In apartment complexes and residential homes to guide occupants to safety during emergencies.
• Hotels and Hospitals: Providing emergency lighting in hallways, stairwells, and near exits for staff and patients.
• Schools and Public Buildings: To guide students and the public safely to exits in an emergency situation.
• Industrial Facilities: Ensures that workers can evacuate safely, even in the event of a power failure.

How the Rechargeable and Direct Power Supply Work Together:

1. Normal Operation (AC Power):

   • Under normal conditions, the emergency exit light is powered by the AC electricity provided by the building’s electrical system.
   • The internal rechargeable battery stays in a charged state, ready to take over if the AC power fails.

2. Power Failure (Battery Backup):

   • In case of a power outage, the light automatically switches to battery power.
   • The internal rechargeable battery provides power to the LED lights, ensuring that exit routes are still illuminated for up to 3-4 hours depending on the light model.

3. Charging and Recharging:

   • When the power is restored, the emergency light reverts to AC power, and the rechargeable battery automatically recharges to be ready for the next outage.
   • A charging circuit ensures the battery is safely recharged without overcharging or damaging the battery.
