Laser Treatment Could Make Plain Light Bulb Much More Efficient
A team of Researchers at the University of Rochester 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.
The 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. The process involves an incredibly short femtosecond laser pulse, which lasts only a few quadrillionths of a second.
It’s not immediately clear how long it would take to commercialize the discovery. But it could be relatively simple to implement in a manufacturing environment once refined.Other technologies are also crowding the field. The U.S. Navy is promoting LED and HID lighting in its ships. Cambridge Researchers say they’ve developed a LED bulb that costs $3 and last 60 years. A technology called ESL is headed to market as well. It will be interesting to see if the Rochester process finds a place on store shelves.
