Question

State any four advantages of light emitting diode (LED).

Hint:

Remember the key benefits: They are {Cheap} to run (efficient), {Long-lasting}, {Tough} (durable), and {Fast} (instant on/off).

Answer 1

Four advantages of Light Emitting Diodes (LEDs) are:
High Energy Efficiency: LEDs convert a much larger percentage of electrical energy directly into light energy compared to incandescent bulbs, which lose most of their energy as heat. This makes them highly efficient and reduces power consumption.
Long Lifespan: LEDs have a very long operational life, typically lasting tens of thousands of hours, which is significantly longer than traditional incandescent or fluorescent lamps.
Durability and Compact Size: Being solid-state devices, LEDs are very durable, resistant to shock and vibrations, and can be made very small, allowing for flexible and compact designs.
Fast Switching and Controllability: LEDs can be turned on and off almost instantaneously and can be easily dimmed and controlled, making them ideal for applications requiring rapid switching and dynamic lighting.
