We are not sure how far LED Lighting can go. Maybe someday we can develop LED with X-ray. In the early stage LED lamp can only be applied to indicator light, calculator screen and digital watch, now it appears in fields with super luminance. High power LED components such as new product LED Flood Lights are used for lighting, but this technology is not quite mature yet. High power LED is of high luminance, yet it also heat up a lot and has high prices.We can see LED (light-emitting diode) lighting is now all around us: it’s blinkering in front of us on the computer screen; it’s shining with smile in the city neon light; it’s lighting up the darkness in the new type of flashlight; it also makes TV screen in the middle of a square possible. The light in the city and the world is owed to our scientists’ effort.The Nobel Prize selecting committee has stated that three scientists have made enormous contribution in the highly efficient and environment friendly blue LED. With LED Lights , we can use this more lasting and highly efficient light to replace original light source, which can not only save more energy, but also light up more places in the world.
