Our cherished as well as ancient wall scones, mercury tube lights, florescent lighting fixtures may soon find the garbage bins. They are going to be obsolete but we may have to wait for a few more years.
What is going to replace the traditional lamps is a film, a plastic film coated with chemicals and sealed by a metal foil. Apply electric current to the resulting sheet, and it lights up with a blue-white glow.
Ok, where can you fix that sheet?
You could tack that sheet to a wall, wrap it around a pillar or even take a translucent version and tape it to your windows.
How it works?
The sheets owe their luminance to compounds known as organic light-emitting diodes, or OLEDs. While there are plenty of problems to be worked out, it’s not the dream of a startup.
OLEDs are beginning to be used in TVs and cell-phone displays, and big names like Siemens and Philips are throwing their weight behind the technology to make it a lighting source as well.
