Light emitting diodes, as most commonly referred
LEDs, is the recent
technological advancement that had revolutionized the world . From wide uses in
laptops to cellular phones or televisions they made the very own place in
almost all gadgets that we often come across. Since the 1970s for incandescent
and CFLS later on LEDs is been used to replace conventional
lighting sources.
Why
LEDs better face of light then other sources ?
Advantages
of LEDs
Efficiency: LEDs can produce more light per watt than incandescent and fluorescent bulbs. This is improving with every new generation of LEDs.
Heat emitted : LEDs radiate very little heat , in contrast to other light sources. Energy is dispersed as heat through the metal base of the LED.
Size: LEDs can be very small, providing flexibility in its application.
On/Off time: Like incandescent lamps and unlike CFL'S , LED's come to full brightness without need for a warm-up time.
Life time: LEDs can have a relatively long useful life lasting from 35,000 to 50,000 hours of useful life, though time to complete failure may be longer. However,fluorescent lamps are rated at about 10,000 to 15,000 hours and incandescent bulbs at 1,000–2,000 hours.
Environmental: LEDs do not contain mercury, reducing the risk of affecting environment.
Disadvantages
of LEDs
· High price: LEDs are
currently more expensive, than most conventional lighting technologies.
· Temperature dependence:
LED performance largely depends on the ambient temperature of the operating
environment. Adequate heat-sinking is required to maintain long life for years.
There is no doubt that the use of LEDs for lighting applications
has the great potential to save energy and allow for new and inventive lighting
methods.Led Bulbs an easy substitute for CFLS is majorly accepted across the
country like India. Where as, LED Street Light, LED
Tubelight , LED PanelLights are widely acknowledged replacing old and traditional methods such as
incandescent and fluorescent .
How does it
effects us ?
The conversion to
LED Light, could approach
an estimated annual saving of 263 terawatt-hours. equivalent of taking 21
million households off the power grid. Reducing load at enormous level from the grids in cities
like Kanpur, Delhi, Mumbai and other cities country wide.
