| Summary: | Light Emitting Diodes (LEDs) are one of the most widely used lighting devices in a multitude
of applications, from light indicators on electronic devices to street light lamps. They serve as
an important replacement for older lighting methods, such as incandescent and fluorescent
lights. LEDs can be compact, have energy efficient properties and longer lifespans compared
to their conventional lighting counterparts. Therefore, these advantages allow it to have the
benefits of being more cost effective and sustainable.
However, LEDs are current-sensitive devices where for such LEDs to be implemented
effectively, the circuit that encompasses the system should support the even distribution of
current throughout the system to maintain their advantages. As an uneven distribution of
current would cause certain LEDs to have deviations in luminosity and their lifespan affected
accordingly.
The purpose of this project is to design and implement a circuit that is capable of dynamically
adjusting the current flow to different strings of LEDs based on any detected abnormalities and
suitably distribute the currents evenly to operate as per in normal conditions to safeguard the
performance and integrity of the LEDs with minimal human intervention. |
