Incandescent light bulbs have been being employed for the last one century, but now with the advent of technology they are very outdated. The primary disadvantage of incandescent light bulbs actuality that almost than 80% energy supplied to them is wasted as heat energy basically 20% is became light for which they are made. Also they provide light of only one color that is yellow which means they are unsuitable for other purposes like indicators, decoration etc. Another disadvantage is their life span along with that is only about 1200 hours which results need of changing them frequently.
It is quite obvious that sooner or later we are gonna be face a power crisis and therefore this factor of power wastage has produced people all on the planet to look a great alternative for these incandescent bulbs. Compact Fluorescent Lamps (CFLs) are e better option over these incandescent bulbs which have a life span of around 6000 hours and consume only about 1/5th of power . that is consumed by incandescent bulbs for producing the lighting of same intensity. But the recent technology that has attracted the attention of everyone could be the Led bulb (Light Emitting Diodes) possess lifespan of 50,000 hours and consumes even lesser power than the CFLs.
A Led bulb employs the semiconductor technology. The Led bulbs can produce light any specific wavelength naturally infrared, visible and ultraviolet. They can emit light of different colors which depends upon the composition of the semiconductor materials used. The Led bulbs therefore find its applications in a large amount places like dashboard in cars, indicators in electronic devices, traffic signal lights and can even replace frequent incandescent bulbs for your family purposes. Normally the light produced along with a single Led is not of high intensity therefore several Led are combined to develop a Led light. The longer lifespan is out of lesser associated with heat printed.
Advantages of Led bulbs over incandescent bulbs could be enumerated as power efficiency. They provide the most prominent advantage will be the form that their power consumption is very low. Another fine benefit is that they can produce light lots of colors. This leads a great sight when implemented with circuits and dynamic light modes.LED bulbs are robust and resistant, can withstand large regarding shock, vibration and temperature variation. Their lifespan is much longer than their incandescent counterparts. And should be also capable of producing flicker free light.
Many countries and organizations like Canada, Australia and also the European Union have already banned or have proposed a ban on the usage of incandescent bulbs due thus several disadvantages and aspects. The Led bulbs have shown very positive results and are considered the best way to replace incandescent bulbs.
