How LEDs work
The led They are increasingly common electronic devices in our daily lives, from lighting to television and cell phone screens. But how do these little light-emitting diodes work? The led They work differently than traditional light bulbs, as they do not use filaments or gases to produce light. Instead, the led They generate light through a process called electroluminescence, in which electrons combine with holes to release photons of light.
– Step by step -- How LEDs Work
- The leds are semiconductor devices that emit light when an electric current passes through them.
- The term »led» means Light Emitting Diode in English, which translates as light emitting diode in Spanish.
- The leds work thanks to the electroluminescence effect, which is the emission of light by a material when an electric current passes through it.
- The LEDs are made up of two types of semiconductor materials: one with a positive charge (known as p-type material) and another with a negative charge (called n-type material).
- The energy released by the union between these materials is what produces the light emission in the LEDs.
- One of the main advantages of LEDs is that consume less energy than other lighting sources, such as incandescent or fluorescent bulbs.
- Another advantage is that they do not generate heat in the light emission process, which makes them safer and more efficient.
- In addition, the LEDs have a longer shelf life than other light sources, making them a durable and cost-effective option.
Understanding How LEDs work is essential in order to fully appreciate the benefits and versatility of these impressive light-emitting devices.
