Abstract:
One of a person's essential needs is light. This study focuses on the feasibility of using light reliant circuits as
an emergency lighting system. The product of the study is an emergency lighting system that substitutes the
needed light in times of unexpected power outage. With this, the emergency lighting systems consisting of
12v strip LED lights, light resistor, battery holder, light reliant circuit, alligator clips, heat controller, metal
mosfet, and ohm resistor were developed. The process requires assembling, soldering the light-dependent
resistor to the gate and source of the IRF740 mosfet to provide connection to the sensor. Following the
device’s development, its functionality would be evaluated in terms of its coverage range, activation time,
and light intensity. The researchers used a lux meter and a tape measure to determine the range of coverage
of the emergency lighting system, resulting in a distance cap of 50 lux at the lowest intensity. Results of the
study showed that the emergency lighting system projected the appropriate lux at a distance of 156.3 cm (5
foot 1 inch) on average, indicating the recommended height or distance allowing the intensity to give more
than a decent aid to brownout situations. Further examination of the findings reveals that there was only one
alteration, which was a 0.02 millisecond difference between trial 1 and trials 2 and 3. Based on the trials, the
average time length is 0.107 milliseconds. With this time length, it’s a conclusion that this emergency lighting
system is responsive enough at needed times and situations and in unexpected times. The average light
intensity of 86,851 lux can be detected by the emergency lighting system. The light intensity would be critical
in calculating the emergency lighting system's proper distance of measurement. Therefore, it is duly
recommended for the household to install the product as it yields good results based on the tests conducted |
