Incandescent light bulbs have been in use for
It is quite obvious that sooner or later we are going to face a power crisis and therefore this factor of power wastage has made people all around the globe to look for an alternative for these incandescent bulbs. Compact Fluorescent Lamps (CFLs) are e better option over these incandescent bulbs which have a life span of about 6000 hours and consume only about 1/5th of the energy that is consumed by incandescent bulbs for producing the light of same intensity. But the recent technology that has attracted the attention of everyone is the Led bulb (Light Emitting Diodes) which have 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 of any wavelength that is infrared, visible and ultraviolet. They can emit light of different colors which depends upon the composition of the semiconductor material used. The Led bulbs therefore find its applications in many places like dashboard in cars, indicators in electronic devices, traffic signal lights and can even replace the common incandescent bulbs for the household purposes. Normally the light produced by a single Led is not of very high intensity therefore several Led are combined to make a Led bulb. The longer lifespan is due to lesser amount of heat produced.
Advantages of Led bulbs over incandescent bulbs can be enumerated as power efficiency. They provide the most prominent advantage is the form that their power consumption is very low. Another fine benefit is that they can produce light of many colors. This gives a great sight when implemented with circuits and dynamic light modes.LED bulbs are robust and resistant, can withstand large amount of shock, vibration and temperature variation. Their lifespan is much longer than their incandescent counterparts. And they are also able to produce flicker free light.
Many countries and organizations like Canada, Australia and The European Union have already banned or have proposed a ban on the use of incandescent bulbs due to their several disadvantages and drawbacks. The Led bulbs have shown very positive results and are definitely the best option to replace incandescent bulbs.
