Design And Construction Of A SMF Battery Guard
Overview
ABSTRACT
The emergency light is an automatic system in which a rechargeable battery-operated light source turns on as soon as the mains power fails. When the mains supply resumes, the lamp turns off. Usually, 6V sealed maintenance-free (SMF) batteries are used in portable emergency lights. Many low-cost lights give no indication when the battery goes flat, so there is the risk of battery failure. This work is on a battery guard circuit for emergency lights having no deep-discharge protection circuitry. It disconnects the bulb in case the battery voltage goes below a safe value (5V).
