What is
a LED light bulbs?
| |
The term LED stands for
Light Emitting Diode. Modern electronics relies heavily upon LED
light bulbs. For instance, LEDs transmit information from remote
controls, are used in traffic lights, digital LED clocks,
flashlights, and to form images on jumbo television screens. LED
light bulbs are miniature bulbs that do not use filaments to
produce light. Therefore, the life of an LED is much longer than
that of a regular incandescent bulb, because there is no
filament to burn out. Incandescent bulbs also tend to be much
larger in size due to the filament, which must be housed in a
vacuum inside the bulb. LED light bulbs last as long as a
standard transistor used in modern electronics, and are lit
purely by the movement of electrons.
The simplicity and long life of the
LED
make its use very
desirable for various technological applications. LED light
bulbs are housed in a durable plastic rather than glass and
perhaps most importantly, are much more efficient. In
traditional incandescent bulbs heat is generated when activating
the filament to produce light.

This
causes energy to be wasted on the production of heat rather than the
production of light. In order to produce the same amount of light as
an LED, an incandescent bulb would have to work even harder. LED
light bulbs save electricity and lower electric bills.
Despite this positive scenario, incandescent bulbs are tailored to
home lighting and will continue to be used until affordable,
household LED light bulbs are available. At present, LED light bulbs
are expensive and recommended for low-light applications such as
porch lights or subdued corner-lighting. (An exception are
chandelier LED light bulbs, which can produce a brighter glow
because there are so many lights working together.) As semiconductor
prices have decreased steadily over the past twelve years, the time
for affordable, brighter LED bulbs is approaching. Prices will be
offset in the long run by savings in electricity and the lifetime of
the bulbs, which is reportedly 30,000-50,000 hours on average.
Until LED light bulbs become more prevalent in the house,
they will continue to light watches, traffic signals, and jumbo
television screens at the local ballpark.
