LED or Light Emitting Diode lighting is a much popular and in-demand lighting technology not just in India but globally. The popularity of LED lights has to do with several factors, particularly its eco-friendliness and durability.
Understanding LED Lights Better
LED works on the principle of solid-state lighting or SSL. Solid-state lighting or SSL is a technology in which light-emitting diodes (LEDs) replace conventional incandescent and fluorescentlamps for general lighting purposes. An SSL device produces visible light by means of electroluminescence, a phenomenon in which electric current passing through a specially formulated semiconductor, diode which causes the semi-conductor material to glow. Today LED lights are used not just for domestic purposes but also in commercial and industrial establishments. LED lights do not contain mercury, thus are safe and do not emit harmful chemicals. The lifespan of a LED lamp is considered to be around one lakh hours while the conventional electric bulbs with tungsten filament is just 1000 hours and CFL bulbs last only 10,000 hours. Also LED only requires less voltage and can also be operated using solar and wind energy.
Benefits of using LED lights
Get increased energy efficiency: Take your average halogen bulb. Of the electricity that it gets, it turns a majority of it, at least 90%, into heat and only 10% gets turned into light. On the other side, LED bulbs just need 15% electrical energy and they turn 85% of it into light and emit lesser heat as compared to halogen bulbs. Thus, LED not only helps decrease your electricity bill but also keeps your home cooler.
LEDs are durable: They have long life span and, you can buy a LED light and forget about its replacement for a long time.
It is more efficient than standard forms: Since LED lights do not contain filament, they are much more resistant to high voltage shocks or any variation in electricity. They don’t break and thus can be used for a very long period.
Compact and many colors option: LED lights are also useful for using in small and compact areas as you can get LED lights of 2mm size as well. LED lamps offer color shades ranging from ‘cool blue’ to ‘warm yellow’ to suit all preferences.
More brightness, and no flickering: As soon as you switch on LED lights, your room is filled with a bright light and hence you do not have to resort to backup lights. Second, they can be switched on and off pretty quickly and that is the reason they are increasingly being used in traffic signals, automotive signals and so on.
LED lights are safer: Since LED lights only use less electricity; they do not get heated up much and are cool. That means your hands won’t burn on touching it. Hence the fear of accidents while handling or fixing it, is negligible. It also does not get spoiled or damaged in rain.
LED lights are eco-friendly lights: If you care for the environment, then LED lights are the best suitable. They do not emit harmful gases as they do not contain mercury and they also do not emit out UV rays which can cause problems ranging from insect attraction to wallpaper and artwork fading. LED lights also emit much lesser CO2 than any other conventional lights. On the downside, LEDs cost considerably more than incandescent lamps and somewhat more than CFLs. However, when the long lifespan of the SSL lamp is taken into account, and the long-term reduction in energy consumption is factored in, consumers may actually save money by using LEDs.
