Everyday we are consuming electricity in our world without thinking exhaustible
source.Have you ever thought that when electricity will be finished or
decreased and what will do at this time.If we don't want to happen this bad
situation, we will take some measures and decrease electricty usages.Option
should move directly to alternative sources like LED lights.In the world many
producers prefer LED lights to consume less electrical energy.Also many
industries like mobile phone,camera use LED lights to provide long battery
life and less battery, so why not we prefer LED lights in our life,we can
use them for our home and we should try LED lights and see difference between
electricity bill before using them.
LEDs, or light-emitting diodes,
are a form of solid-state lighting that is extremely efficient and
long-lasting. While incandescent and fluorescent lights consist of filaments in
glass bulbs or bulbs that contain gases, LEDs consist of small capsules or
lenses in which tiny chips are placed on heat-conducting material
Let's see the advantages of LED lights.The
future of household lighting will soon be the wide spread adoption and use of
white energy efficient LED light bulbs.LED lighting applications will be
powerful and cheap enough to replace incandescent lighting for everyday use in
our homes, in street lights, outdoor signs, and offices.
Size and Efficiency
LEDs measure from 3 to 8 mm long and can be used singly or as part of an
array. The small size and low profile of LEDs allow them to be used in spaces
that are too small for other lightbulbs. In addition, because LEDs give off
light in a specific direction, they are more efficient in application than
incandescent and fluorescent bulbs, which waste energy by
emitting light in all directions.
Long Life
The life of a high-power white LED is projected to be from 35,000 to 50,000
hours, compared to 750 to 2,000 hours for an incandescent bulb, 8,000 to 10,000
hours for a compact fluorescent and 20,000 to 30,000 hours for a linear
fluorescent bulb. LED lifetimes are rated differently than conventional lights,
which go out when the filament breaks. Typical lifetime is defined as the
average number of hours until light falls to 70 percent of initial brightness,
in lumens. LEDs typically just fade gradually.
Lower Temperatures
Conventional lightbulbs waste most of their energy as heat. For example, an
incandescent bulb gives off 90 percent of its energy as heat, while a compact
fluorescent bulb wastes 80 percent as heat . LEDs remain
cool. In addition, since they contain no glass components, they are not
vulnerable to vibration or breakage like conventional bulbs. LEDs are thus
better suited for use in areas like sports facilities and high-crime
locations.
EnergyStar LEDs
Poorly designed LEDs may not be
long-lasting or efficient. LEDs that are EnergyStar-qualified should provide
stable light output over their projected lifetime. The light should be of
excellent color, with a brightness at least as great as conventional light
sources and efficiency at least as great as fluorescent lighting. The LEDs
should also light up instantly when turned on, should not flicker when dimmed
and should not consume any power when turned off.
We can understand that there are many advantages usage of LED lights.Some well known automobile industries like Audi and Opel use LED lights to provide attractive view.
