Light Emitting Diodes
Many people are probably familiar with the term LED. It usually reminds
us of displays seen on alarm clocks or inside of car
dashboards. But do you know what the term LED really means? LED is
short for light emitting diode. Light
emitting diodes are small semiconductors that emit a bright light
when they come in contact with
electricity. You may wonder why certain LED
lights are different colors than others such as red, blue, or green.
The cause for the different colors is the result of different chemical
make ups of the
material used for the lights. Believe it or not, most light
emitting diodes are made up of minerals such as zinc, aluminum, or
silicon. Depending upon the type of material, the lights may burn bright
colors of green, red, or other colors. There are many benefits to
choosing items lit with this method versus traditional light
bulbs. In fact, more and more products today are being lit with the
use of these light
emitting diodes.
Christmas lights are a prime example of LED’s popularity. Of course,
anything with a gauge type display today is usually used with LED
lights. There are many traits to these light emitting diodes which
make them more appealing than a regular light such as the fact that they
can last for many years, while light
bulbs only tend to last a few months or so. In fact, most LED
lights can last for almost ten years! Another plus is that because
of their size and structure, they are less likely to break and shatter
as compared to their counterparts. You may be surprised as to where these
light emitting diodes are found. Some surprising places include the moving billboards in
Times Square, many new outdoor floodlights, and traffic signals. Just
look around and you’ll discover just how useful the LED light really
is.
