Understanding the Context

Video Shows Chrisean Rock Getting Slapped by a Woman, Then Fighting Multiple People LEDs have many advantages over incandescent light sources, including lower power consumption, a longer lifetime, improved physical robustness, smaller sizes, and faster switching. LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work?

Key Insights

An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light. An LED (light-emitting diode) is a semiconductor device that emits infrared or visible light when charged with an electric current. To this moderately convoluted situation, add the past tense and past participle of the verb lead, which is led and pronounced like the metal noun lead with a short e. LED works by passing electricity through a semiconductor, which releases energy in the form of light. This process makes an LED highly efficient, durable, and versatile, finding its applications in everyday devices such as smartphones, TVs, and home lighting systems.

Final Thoughts

Unlike traditional incandescent bulbs or fluorescent lamps, an LED is a semiconductor device that emits light when electrical current passes through it in the forward direction. What is a Light Emitting Diode (LED)? A Light Emitting Diode (LED) is a special type of PN junction diode. The light emitting diode is specially doped and made of a special type of semiconductor. This diode can emit light when it is in the forward biased state.
