June 26, 2007—CeeLite™ light emitting capacitor (LEC) panels using Eastman Chemical Co.’s patented Encapsulation Technology and Spectar copolyester can provide versatile lighting solutions for self-installed interior signage applications and such outdoor applications as advertising on buses and billboards, retail window signage, street signage, and sports and entertainment mobile merchandising.

In Louisville, Ky., the panels create 2-1/2-by12-foot backlit ad displays on each side of a bus.

Used for electronics and surface lighting projects for the past two years, the LED panels stimulate light-emitting natural phosphors embedded between thin plastic sheets with electrodes. Growing market demand for more robust LEC panels for retail and other applications led to the agreement between CeeLite and Eastman. Eastman’s proprietary Encapsulation Technology uses Spectar copolyester as the transparent substrate to encapsulate images, textiles, botanicals, and natural inclusions, along with LEC panels, for architectural and surface lighting applications.

Spectar sheet can be used in the ultra-thin gauges LED panels require, and the product can be cleaned with most cleansers used on outdoor panels. Spectar can be cut, drilled, routed, and screwed without the need for special tools.

The new panels can transform any surface into a light source using minimal quantities of electricity relative to incandescent, neon, and florescent lights.
