Application of an AC voltage to both conductive layers generates a changing field within the active layer, this causes the litcoat pigment to emit light.
The EL lamp is constructed from various layers of HVLP spray painted Polymer Thick Film coating compositions. Litcoat EL paint users are developing ever more creative ways to capitalize on its unique qualities.
The first powder electroluminescent pigment was introduced in 1930 by Mr. Destriau a French scientist in Magnetism and Dosimetry . He was the first who came up with the word “electroluminescence”, as a reference to the phenomenon he observed in 1936. He called it the Lossew light after a Russian scientist Oleg Losev. Losev who invented the first light-emitting diode (LED). He did the first research on them and proposed the first correct theory of how they worked. He later used them in practical applications such as electroluminescence.
After the invention the electroluminescence effect wasn’t heard off anymore until the 60’s when the inventions where used to make products which we still use today.
The science of Electroluminescent paint
Electroluminescence science (EL) is an optical phenomenon and electrical phenomenon. The material in this optical phenomenon emits light. In response to the passage of an electric current or to a strong electric field. Electroluminescence is the production of visible light by a substance exposed to an electric field without thermal energy generation.
An EL coating sytem requires 60-250V AC, and frequency range from 50-1000Hz.
Typical Operating Voltage 100-120V AC RMS, recommended for most applications.
