AMERICAN SCIENTIST INVENTS
PLASTIC LIGHT BULB
A US scientist has invented a new kind of
light bulb that uses plastic polymers and nano materials to generate light that
is more energy-efficient than current fluorescent lights and is easier on the
eye.Details of the new invention were published Monday on the website of Wake
Forest University in North Carolina, where the inventor, physics professor
David Caroll, is based.The new plastic lighting uses the same amount of
electricity as LED bulbs and half as much as fluorescent bulbs. The device is
made of three layers of white-emitting polymer blended with a small amount of
nano-materials that glow when stimulated with electrical current to create
bright, perfectly white light similar to the sunlight human eyes prefer. It can
be made in any colour or shape — from flat sheets to replace office lighting to
standard bulbs in household lamps.
“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 Dr. Carroll.Dr.Caroll is the
director of the Centre for Nanotechnology and Molecular Materials. “The new
lights we have created can cure both of those problems and more.”
