Why LED light is worldwide applied now?

A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for general lighting. Appearing as practical electronic components in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness. Now, when talk about the lighting, we think about these three letters, LED. But why people love LED light so much, it should be time for finding the answers.

They do more for less. LED's are efficient-producing a lot of light from a little power. For example, one 5-watt LED can produce more light than one standard 75-watt incandescent bulb. The 5-watt LED could do the job of the 75-watt incandescent at 1/15 of the energy consumption. LED's save energy and, therefore, money. This is because in LED lights, 90% of energy is converted into light, while in incandescent bulbs 90% of energy goes to heat and only 10% to visible light.anty881209wong 140113

They last longer. LED is virtually maintenance free - they don't have a filament that will burn out, so they last much longer. A standard "long life" household bulb will burn for about 2,000 hours. An LED can have a useful lifespan up to 100,000 hours! By some sources, LED's can last for as long as 40 years. Imagine not having to change a light bulb for years. There are LED products available this year that will make frequent light bulb changes so 20th century.

It looks nice. The prime replacement for the incandescent light bulb would be the higher-efficiency compact fluorescent, or CFL. However, besides that there is toxic mercury in the design, it gives off a strange, sometimes unpleasant color that even gives some people headaches. Not the LED- its light is easy to see even in bright sunlight and can produce the same soft, white light as a regular bulb. LED light can be illuminated and change its light to many colors including a very recent addition of White and Blue. Other is Green, Red, Orange and Amber.
