Why LED lights are so popular
LED lights have become so popular due to their energy saving capacity, this means that they are
better for the environment and that they also keep energy bills low. Compared to incandescent
lights, LED lights have a longer life span.
The difference between LED lights and incandescent lights is that LED lights do not have a wire
filament or any type of filament for them to produce light which results in making them much more
energy efficient while still producing the same amount of quality lighting. LED lights are illuminated
solely by the movement of electrons in a semiconductor material, that semiconductor material is
usually silicon; nowadays silicon is at the heart of every electronic device. The benefit of having
silicon is that it tricks the electrons because it looks metallic. However silicon is in fact not metallic
nor do they have any free electrons to conduct the electrical current and it is because of this that
the silicon crystals act more of an insulator rather than a conductor.
On the other hand incandescent lights get their source of light through the wire filament. The wire
filament excites the electrons and the energy the electrons produce is given off in the form of light.
The absence of the wire filament in the LED light makes them more popular because it reduces heat
loss meaning it can use more energy for light. The absence of the wire filament in a LED light makes
them more resilient which is another factor which adds to their popularity. Many incandescent
lights do not work because the filament has been damaged and/or broken; even if you handle the
light bulb very carefully there is still the possibility of it breaking. For an incandescent light to work
effectively the wire filament needs to get a lot of heat which makes them very dangerous as it can
easily burn people if they are touched.
Due to them being energy efficient, LED lights and compact fluorescent lights have become
extremely popular. Due to them being popular LED lights still take the lead due to their slight
differences.
The reason LED lights are so popular are down to their durability, long lifespan and easy installation
they also contain no hazardous substances. On the other hand CF lights may require speciality
fixtures, they are also easily breakable and have a lifespan about one-fifth that of a LED light, also
CF lights contain mercury which can become very dangerous when the gas is released. Also because
CF lights take a long time to heat up it means that it takes a long time for the light to fully brighten
up. Also it is useful to know that when you switch a CF light on and off you are shortening their
lifespan.
