Queen's researchers shine light on compact fluorescent bulb problems
Date:4/7/2009

xtra power consumed by the current compact fluorescents. As for dimmability, Dr. Jain says it too is an efficiency issue and not just a nuisance for consumers. "In fact, when a CFL is used with a dimmer switch, its bulb can burn out sooner than expected," he says.

The solutions emerged when John Lam, a PhD candidate working with Dr. Jain, developed a compact, simplified circuitry and controller design that overcomes the power problem while also meeting consumers' need for a dimmable, inexpensive CFL. "Understanding the significance of the problem motivated me to work hard at finding a solution," Mr. Lam says.

The two main challenges were making the technology directly replaceable with existing designs, and economical to produce, says Dr. Jain. "We were able to develop a more power-efficient, dimmable and cost-effective CFL technology that can truly replace the power-hungry incandescent light bulbs. This makes it very attractive to the consumer market."

The work was carried out at Queen's Centre for Energy and Power Electronics Research (EPowER), which tackles key problems in the area of energy conservation and brings those solutions to industry.

PARTEQ Innovations, the technology transfer office of Queen's, will work with major CFL manufacturers to bring the technology to market.

"This is an excellent example of university research providing an innovative solution well in advance of a potential market problem," says John Molloy, President and CEO of PARTEQ. "The key to providing useable innovation is understanding the problems of existing technology and finding elegant solutions. Here we have a motivated researcher who saw a key problem and delivered the solution to an industry in need, in time to make a difference."
