LED (Light Emitting Diode)
makerA light-emitting diode is a semiconductor device that emits light when an electric current passes through it.
expanded
Light-emitting diodes (LEDs) convert electrical energy directly into light via electroluminescence. They are characterized by their high efficiency, long lifespan, and ability to generate different colors without filters. LEDs are integral in applications ranging from indicator lights in electronic devices to energy-efficient lighting solutions in residential and industrial settings.
examples
A 5 mm red LED with a forward voltage of approximately 2 V and a maximum current rating of 20 mA.
Commonly used in DIY electronics projects for status indication in hobby circuits.
A 100 W LED floodlight with a luminous efficacy of 120 lm/W, resulting in a total output of 12,000 lumens.
Used in commercial spaces for area lighting, providing significant energy savings compared to traditional halogen lights.
