Now, why is the blue LED so important? Quite simply because there are no white LEDs. The white light that our eyes detect is created by using a blue LED and some yellow phosphor. The yellow phosphor coating may be placed directly on the blue LED or on the glass envelope that houses the blue LED. Either way when the blue light from the blue LED passes through the yellow phosphor the resulting light appears to be white.

In late 2014 at the Nobel Prize Award Ceremony in Stockholm, Sweden, the three Japanese scientists who developed the blue LED while working at Nichia Chemicals will share the Nobel Prize in Physics for their work on the blue LED. In official terms the Nobel Committee awarded this year’s physics prize to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura “for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources.”

Furthermore, the Nobel Committee pointed out in its announcement that the results of all the scientists’ hard work will be on display everywhere as the three recipients make their way through Stockholm: “the light from their invention will be glowing in virtually all the windows of the city.” And they can be assured that, as this century progresses, the ascendancy of the LED will only become more dramatic.

We usually expect to find wiring troubles in old homes where the wires are made from out-of-date material that is no longer up to code. But electrical repair needs can crop up in the most modern homes: all it takes is a bit of shoddy installation or damage to a few connections and you can end up with wiring that malfunctions, leading to power loss or—in the worst case scenario—an electrical fire.

Do not attempt any repairs to your wiring yourself unless you are a trained electrician with access to pro-level tools. High-voltage shocks are something to take seriously. Pick up your phone instead and put in a call to your local electrician and arrange for repairs.
