Luminescence is achieved when the characteristics of certain substances emit absorbed energy. With a luminescent lamp you have light that is generated via radiant energy without creating temperature. The stimulation of luminescence by electricity is called electroluminescence (EL).
An organic phosphor is affixed between two conductors. When an AC signal of sufficient voltage and frequency is applied to the conductors an electric field is formed across the phosphor and causes it to emit visible light. Most of the phosphors used in the technology can only emit white or pink light. Colored overlays are used to attain additional colors. EL was originally developed in 1936, but was not made commercially viable until the early 1990s. Since then, the technology has been refined into a high tech process that can be used on virtually any application. |
