A Light Emitting Diode (LED) is a kind of semiconductor source of light designed for a range of purposes. It is included in indicator lamps in a great many devices, office room lighting, aircraft lighting, traffic signals, etc. In addition to that infrared LEDs are being used in remote device systems in electronic equipment like Television set, DVD players, etc. Commercially, LEDs can be used in place of incandescent and CFL lamps by considering its advantageous financial savings over the classic lighting systems.
One of the most important advantages of LED lighting systems include its high luminous efficacy, meaning how good a light source makes visible light. More than that LEDs are high efficiency as they emit just a small amount or essentially no heat when compared to the incandescent lights. We can look at the advantages of LEDs one by one:
1. About the efficiency, LEDs will generate a lot more light per watt input in comparison to the traditional ways of lighting. Even though efficiency of fluorescent lighting fixtures could depend on its shape and size, it truly is of lowest with regards to LEDs.
2. Classic lighting methods create light at different colours by making usage of color filters. But LEDs do not require such color filters and therefore are more effective.
3. Another advantage is the fact that measurements LEDs is as tiny as 2 mm when compared with the older methods of lighting fixtures.
4. If you’d like to have rapid illumination for an area, it’s suggested make use of LED lights because they can illuminate instantly. It is very crucial in the case of vehicle indicators that a red indicator light should gain full brightness within a microsecond. To ensure that it can serve its purpose promptly to other drivers and thereby stop accidents.
5. People often state that LEDs emit only less amount of heat when compared with other means of less efficient lighting. It will help you to reduce the damage caused to sensitive objects and fabrics.
6. We know that incandescent bulbs will stop operating all on a sudden without giving any sign of its imminent failure. But LEDs are not so. It will produce a dim light over time and will gradually stop its operation.
7. Another greatest benefit from LEDs is related to its life span. Its lifetime is relatively higher than that of incandescent (duration of only 1,000 to 2,000 hours) and fluorescent tubes. LEDs life-time is more than 50,000 hours compared to only 15,000 hours of Fluorescent lamps.
8. Even though LEDs cost a greater amount at first, you’ll be able to cut back the maintenance cost and the repeated replacement costs. Therefore , in the end LEDs are going to be more profitable than the low cost, low efficient traditional fluorescent, incandescent, and CFL lighting systems.
We realize that the world is fighting with Global Warming with adverse climate change. As LEDs avoid the use of damaging gases like sodium or mercury, the use of LEDs can certainly decrease the additional emission level of Green House Gases which present a critical obstacle to the existence of the Ozone layer. Because of this LED lighting systems are regarded as an alternative form of energy along with its advantages over the traditional lighting methods like incandescent lamps, fluorescent tubes, CFL lighting, etc.
