Laser Treatment Could Make Plain Light Bulb Much More Efficient
Could a regular light bulb end up being an energy efficient competitor to a compact fluorescent bulb? Researchers at the University of Rochester say yes.
A team of optics researchers at the school say they’ve developed a process that makes a 100-watt incandescent bulb use less electricity than a 60-watt bulb. The process, they say, would keep the cost of a traditional light bulb well under that of its fluorescent counterpart while maintaining the more pleasant light an incandescent bulb gives off.Professor Chunlei Guo (pictured above) and his team developed a laser process that treats the tungsten filament in a traditional bulb. The process creates nano- and micro- level structures on the filament that dramatically improve its efficiency.
