Light-Emitting Capacitor Impresses Time

Light emitting capacitor (LEC) technology developed by CeeLite, Blue Bell, Pa., using Sylvania advanced phosphors, was named among the “Best Inventions of 2006” in a year-end issue of Time magazine.

CeeLite's LEC technology consists of printable, flexible, paper-thin film panels that can turn any surface into a light source. The LEC panels can be used for a wide range of indoor and outdoor signage, architectural and entertainment lighting applications, including transit advertising, point-of-purchase signage, window display and studio and stage lighting.

The panels are constructed by sandwiching Sylvania phosphors between two electrodes and screen printable, recycled compositions. The application of AC voltage generates a changing electrical field across the phosphors causing them to emit light. The technology offers 99 percent uniform surface illumination and energy savings by consuming little power and generating negligible heat.

“Sylvania's higher quality light-emitting phosphors provide CeeLite's LEC panels with the color and brightness necessary to make our product a platform technology that is destined to redefine the way lighting is used today,” said Gabrielle Santulli, marketing director, CeeLite. “Phosphors afford us the flexibility to turn any surface into a light source both indoors and outdoors for backlit applications such as advertising, street signage, consumer electronics, home décor and clothing.”

Recent CeeLite applications include a massive interactive illuminated window display featuring Madonna at H&M's New York City flagship store, a sound-activated, illuminated drum set for the Red Hot Chili Peppers latest concert tour, the CNN Headline News set, Moog synthesizers, Firefly PC keyboards and Back-Lite jackets.
