What Is LED Technology?

A relatively low-energy means of emitting light, light emitting diode
(LED) technology is used in many electronic devices used frequently in
the average home. LED is different from the standard light bulb seen in
most homes because it uses an electrified semiconductive material to
produce light instead of an electrified filament. A nearly omnipresent
form of lighting, LED technology is used in computers, televisions,
remote controls, and flashlights, as well as in signs, traffic lights,
and architectural and stage lighting.
In an LED light, electrified energy causes the semiconductor contained
inside the LED bulb to emit light. Used to produce blue or white light,
nitride is one of the most common semiconductors applied in LED
modules. LED technology is used in newer television sets, where it is a
replacement for the cathode ray tube (CRT) lighting which was common in
the past. In LED televisions, clusters of LED diodes are arranged into
panels that are triggered to light and color the picture on the screen.
Televisions lit with LED technology are more energy efficient, slimmer
in profile, lighter weight, and more environmentally friendly in
disposal than the old CRT televisions, but they are also more
expensive.
Though the use of LED technology for simple lighting is more costly to
set up than lighting with standard bulbs, LED technology offers a
number of advantages. Because the tiny metal thread known as the
filament is prone to heat weakening and breakage, LED bulbs are more
durable and long-lasting than standard filament bulbs. They are less
prone to breakage than fluorescent bulbs and they consume much less
energy than either standard light bulbs or fluorescent bulbs.
LED diodes can be designed to have one color, or they can be designed
to have several colors of light contained within one diode. The ability
to change color using multi-colored LED diodes powers many high-tech
LED screen like those used on large LED signs. The LED screen at the
Fremont Street Experience in Las Vegas, Nevada, is among the largest
true LED screens in the world. Though Las Vegas is well-known for its
flashy lights and impressive LED signage, the screen, called Viva
Vision, is significantly larger than any other LED panel in the city,
extending about five football fields long and powered by approximately
12 million LED diode modules.
In addition to its applications in business and architectural design,
LED technology can also be used for fun and entertainment. Countless
inexpensive novelty LED items provide an array of interesting lighting
for party favors. LED bulbs power many flashy toys, including glowing
ice cubes, flashing jewelry, multicolored LED hair clips and
scintillating belt buckles. Decorations lit by LED are often used to
lend a high-tech futuristic look to an event or party.
