Abstract
Abstract An illumination system with a panel that is capable of producing electroluminescence as well as reflecting incident light independent of the electroluminescence function of the panel. A layer of phosphor is excited by a power source, and a reflective layer disposed on top of the phosphor layer reflects incident light from an outside light source. The reflective layer is transparent and does not interfere with the electroluminescence of the panel.
