Broken-Compact-Fluorescent-Lamp_CFL__71862-150x150Shattered compact fluorescent light (CFL) bulb releases mercury

David Carroll, professor of physics at Wake Forest University, NC, and his team developed a shatter-proof, long-lasting, flicker-free, mercury-free, hum-free light bulb—the Fipel, the acronym for the technology on which the concept is based:  field-induced polymer electroluminescence.

The malleable bulb will be available in any shape and size, from large sheets for commercial applications to small household bulbs.

Fipels are at least twice as efficient as CFLs and are long-lasting—Carroll reports he’s had one burning in his laboratory for nearly a decade.

He explains that his innovation consist of “ . . . three layers of a white-emitting polymer that contain a small volume of nanomaterials that glow when electric current is passed through them.”

Users will find that Fipel light is much warmer than the light emitted from fluorescents.

Of these bulbs, Carroll says, “They have a bluish, harsh tint to them.  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 curlicue bulbs and I can give you any tint to that white light that you want.

“What we’ve found is a way of creating light rather than heat.  Our devices contain no mercury, they contain no caustic chemicals and they don’t break as they are not made of glass.”

The inventor says the Fipel is cheap to make and that he has a corporate partner interested in producing the bulbs.  He expects the first units to be available in 2013.
