New flicker-free lighting to replace fluorescent bulbs

Researchers have created a new technology which provides flicker-free, shatterproof lighting which is easy on the eyes and may soon replace the buzzing overhead fluorescent light bulbs in your office. The lighting, based on field-induced polymer electroluminescent (FIPEL) technology, also gives off soft, white light - not the yellowish glint from fluorescents or bluish tinge from LEDs, claim scientists at Wake Forest University.

"People often complain that fluorescent lights bother their eyes, and the hum from the fluorescent tubes irritates anyone sitting at a desk underneath them," said David Carroll, the scientist leading the development of this technology at Wake Forest. "The new lights we have created can cure both of those problems and more," Carroll said in a statement. The team uses a nano-engineered polymer matrix to convert the charge into light. This allows the researchers to create an entirely new light bulb - overcoming one of the major barriers in using plastic lights in commercial buildings and homes. The device is made of three layers of moldable white-emitting polymer blended with a small amount of nanomaterials that glow when stimulated to create bright and perfectly white light similar to the sunlight human eyes prefer.
