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.

The chandelier used to mark your arrival. Clad in crystal, it met you in the foyer of a well-appointed home, then dazzled you from a power position over the dining room table.

Rarely did you find a chandelier in a starter home. To see them illuminating any room other than one used for entry or dining, more unusual still.

My, how times have changed!

Today chandeliers rate as a brilliant idea just about anywhere — from modest homes to magnificent mansions, contemporary digs to traditional houses. They dangle decorously in almost every room of the house.

Credit our bigger-is-better building boom. Taller ceilings and increased volume in today’s homes means chandeliers are less likely to crowd a room.

“Nine-and-10-foot ceilings almost demand something hanging to fill the space,” says Joe Rey-Barreau, educational consultant for the American Lighting Association (ALA) and assistant professor of interior design at the University of Kentucky. The ALA is a non-profit organization of leading manufacturers, retail lighting showrooms and sales representatives in the U.S. and Canada dedicated to expanding public knowledge about lighting.

Colorful chandeliers create drama in the kitchen. Mini ones provide elegance to powder rooms. Even walk-in closets go upscale when lit with a small chandelier.

“Beyond laundry rooms and garages, any room is an open target for hanging a chandelier,” adds Rey-Barreau. “More commonly, kitchens and bathrooms have become the popular locations for chandeliers.”

Chandeliers add twinkle to a boudier. “People are treating their bedroom suites as more luxurious personal spaces with elaborate bathroom areas, so it is not unreasonable to consider chandeliers there, either,” says Dan Blitzer, Director of Education for the ALA..

1) Totally Tubular

We’ve seen words written on walls in LED rope, but never with this kind of frame. How clever! As the evolution of LED rope continues, I would expect to see even more eye-catching wire frames. It’s all about making something that looks good even when rope is not illuminated. This DIYer is definitely on the right track.

3) LED Rope with a Side of More Rope

It seems to be true. She wore garments with integrated LEDs at the Grammy’s and loves to have LED lighting on stage with her. Here, we can see how cool LED rope can be on the stage. There are innumerable shapes and symbols that could be constructed or outlined with LED rope to make a musical performance more visually appealing. Rock on!

5) Wrap Your Porch like a Present

Using rope to play with LED rope has become wildly popular during the past year or so. I love the way this piece displays what I think of as a controlled tangle. This lighting application is artistic in the way it arrest attention and invites questions. Like, “What is the point of this?” And you’re led to answer yourself: It’s a source of light that serves a function while it conveys a unique look. Good stuff.

7)  LED Rope for Starting Seedlings

This is another application that is not new but should be restated. LED rope is a great, relatively inexpensive way to install cove lighting. This is great in residential and commercial settings and needs to be restated because cove lighting creates such a dramatic transformation for any space, and LED rope is just an excellent way to achieve it.
