How LED Lights Work?

LED stands for Light Emitting Diode. LED is now found on almost every electronic device including MP3 players, DVD players, TV's, clock radios and computers. LED's have been popular for decades, however today they are cheaper, brighter and come in more colors than ever before. While the incandescent light bulb has been the light of choice for at least 100 years, many believe the LED will soon replace it.

LED's are very similar to traditional light bulbs, except that they fit directly into an electrical circuit. LED's do not have a filament, so they generally last for a long, long time without burning out. Because there is no filament, LED's do not get hot and require far less electric power than traditional light bulbs due to their efficiency. In fact, LEDs are illuminated by electrons that run through the semiconductor material that LEDs are connected to.

An LED is a light emitting diode. A semiconductor diode is a two-terminal device, sometimes described as a pn. An LED is fabricated from a semiconductor material. One side of the semiconductor is attached to the P side which is the anode; the other side of the semiconductor is attached to the N side, the cathode. Electricity can flow from the p side to the n side. However, no electricity can flow in reverse. In effect, therefore, a diode is a unidirectional conductor.

Common components of an LED include: A whisker which is connected to the anode, the anvil, which is connected to the cathode, a lens to illuminate the light created for distances and a high impact plastic casing to protect the LED.

LEDs are available in a variety of colors. While popular colors include red, yellow and green, one of the most difficult colors to create is white. In fact, it is currently not possible to create pure white for mass production. Most LED flash lights or light bulbs today that are white in color are actually not pure white, but whitish-blue.

There are many reasons why LED Light bulbs continue to be popular. Here are some of the main benefits they offer:

LEDs are extremely efficient and require very little current to illuminate. Since they do not have a filament, LEDs don't heat up, making them perfect for many electronic applications where heat is detrimental. In a traditional light bulb, the vast majority (sometimes more than 80%) of the electricity used to illuminate a light bulb is wasted not in light, but in heat.

LEDs are manufactured within an epoxy resin epoxy, which means that that they are virtually indestructible. Compared to a traditional light bulb, an LED is far more durable.

LEDs can be mass produced. Just like traditional light bulbs, they are extremely affordable to produce in large numbers.

LEDs are considered to be solid state devices. Solid state refers to any item that has no moving parts. When an item has no moving parts, it is generally more reliable because of less friction and fewer parts that can malfunction.

In the past year, though, lighting manufacturers have introduced LED bulbs in a shape Edison would recognize that put out a decent amount of good-quality light. They still don't give off light from all sides as incumbent technologies do, but this latest generation of LEDs does a better job dispersing light, which means that you could use one (or a few) for overhead lighting.
