If this technology can move beyond the hype, then we might have an answer to expensive, color-limited LED lights and bulky fluorescent tubes…
Say goodbye to that annoying buzz created by overhead fluorescent light bulbs in your office. Scientists at Wake Forest University have developed a flicker-free, shatterproof alternative for large-scale lighting.
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.
“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.”
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 research supporting the technology is described in a study appearing online in advance of publication in the peer-reviewed journal Organic Electronics.
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. However, it can be made in any color and any shape – from 2×4-foot sheets to replace office lighting to a bulb with Edison sockets to fit household lamps and light fixtures…
