EL, or electro luminescent signage, is essentially a flat light bulb sandwich consisting of layers of conductive and non-conductive plastic and a layer of phosphor. The phosphor is laminated between two conductive layers and, as a voltage is applied between the two conductive layers, or electrodes, the phosphor emits light energy. When a high-quality, high-resolution image is printed over the light, it behaves like a backlit sign. The illuminated phosphor does not generate heat the way conventional light sources do so EL runs cool. You can encapsulate or enclose the panels without fear of them overheating or melting.
EL Badges could be used all year around in the culture festivals, theme parks, holiday celebrations and tourist-attractive locations. These badges can be powered by just a pair of AAA cells and can last for 12 hours continuously. Take a look - seeing is believing!
