Design And Construction Of A Smart Emergency Light
The design and construction of a smart emergency light involve the creation of a sophisticated illumination system tailored for emergency situations, integrating advanced technologies to enhance functionality and usability. This innovative lighting solution encompasses various elements, including robust hardware components, such as high-efficiency LED bulbs, rechargeable batteries, and motion sensors, to ensure reliable performance during crises. The incorporation of intelligent features like automated light activation upon detecting motion or power outages, adjustable brightness levels for energy conservation, and remote control capabilities via smartphone applications enhances versatility and user convenience. Moreover, integration with smart home systems enables seamless integration with other devices for enhanced automation and monitoring. Through meticulous design and engineering, a smart emergency light emerges as a versatile and adaptive solution, providing illumination and safety assurance during unexpected events, thereby offering peace of mind and security to users.
ABSTRACT
An emergency light can come in handy at all sorts of time, especially when there’s a power outage. This work is on a white LED-based smart emergency light that automatically turns on when mains power supply fails.
The circuit consists of power supply, battery charger and switching sections. The power supply and charger sections are built around transformer X1, diodes D1 and D2, transistor T1, resistors R1 and R2, and zener diode ZD1. The power supply for the circuit is derived from AC mains by using 9V-0-9V, 250mA step-down transformer X1. Diodes D1 and D2 rectify the AC voltage into DC voltage, which is smoothed by filter capacitor C1. The unregulated DC voltage is regulated by transistor T1 along with resistor R1 and zener diode ZD1. The regulated DC voltage, via resistor R2, charges the lead-acid battery.
