A lighted heat dissipating panel made of sustainable renewable materials such as recycled aluminum and soy-based urethane, for use in architectural or shelving applications. The panel may be flat, rectangular, curvilinear, or of varying cross section so as to include any three-dimensional shape as desired. Lightweight materials such as carbon fiber, fiberglass, resin, soy-based urethane, and similar materials are used in combination with thermally conductive structural materials, such as expanded aluminum honeycomb, preferably fabricated from recycled aluminum, to provide a stiff, lightweight, machinable, moldable, and thermally conductive panel for use with lighting elements. Lighting elements are housed within the panel, providing illumination as desired. Heat is transferred from the lighting elements through the panel to the supporting structure and radiated from the panel itself, providing cooling effect for the lighting elements, reducing the temperature in the immediate vicinity of the lighting elements and providing for longer lighting element life.
