A team of scientists from Wake Forest University has introduced a new light bulb which could replace typical fluorescent lights in near future. The new lighting source is two times more efficient than the traditional fluorescent bulbs. The new bulb throws a soft white light rather than a yellowish light as fluorescent bulbs do.
A scientist from the team, David Carroll said, “People often complain that fluorescent lights bother their eyes, and the hum from the fluorescent tubes irritates anyone sitting at a desk underneath them. The new lights we have created can cure both of those problems and more.”
Scientists used Polymer Electroluminescent Technology to keep the rooms free from a yellow tint. They convert the charge into light with a nano-engineered polymer matrix. The matrix has three layers of moldable white-emitting polymer blended with a small amount of nanomaterial. When this material is stimulated – bright white light was created.
You can also change the color and shape of the material to create light of various colors. This feature is included to provide flexibility – to create office lights or household lamps. These bulbs can also be used at large display lighting.
