Plastic bulb development promises better quality light

By Matt McGrath
Environment correspondent, BBC News




US researchers say they have developed a new type of lighting that could replace fluorescent bulbs.

The new source is made from layers of plastic and is said to be more efficient while producing a better quality of flicker-free light.

The scientists behind it say they believe the first units will be produced in 2013.

Details of the new development have been published in the journal Organic Electronics.

The new light source is called field-induced polymer electroluminescent (Fipel) technology. It is made from three layers of white-emitting polymer that contain a small volume of nanomaterials that glow when electric current is passed through them.

The inventor of the device is Dr David Carroll, professor of physics at Wake Forest University in North Carolina. He says the new plastic lighting source can be made into any shape, and it produces a better quality of light than compact fluorescent bulbs which have become very popular in recent years.

"They have a bluish, harsh tint to them, " he told BBC News, "it is not really accommodating to the human eye; people complain of headaches and the reason is the spectral content of that light doesn't match the Sun - our device can match the solar spectrum perfectly.

"I'm saying we are brighter than one of these curly cube bulbs and I can give you any tint to that white light that you want."  (...)
