Electroluminescent film is a device in which a layer of light emitting phosphor is printed between two very thin electrodes, one is opaque and the other is transparent. When alternating current is applied, the phosphor rapidly charges and discharges, resulting in the emission of light that could be blue, green, orange or white. Many additional colours can be achieved by adding dyes and filters to the active EL area. Electroluminescent film offers numerous advantages over other lighting sources: low thickness, generating no heat, energy efficient, providing uniform lighting with no dark areas and versatility.
In particular Grado Zero Espace's staff thought to integrate these electroluminescent devices into some garments used in sport applications where high visibility is a key point. So here is the motorcycling jacket (LQ Jacket) with an electroluminescent film completely integrated on the back and controlled by a power head inside. This element solve the visibility problem with a flexible and washable system. Another example is the S1 sailing suit that comes from the Transat 6.50 experience and, in the updated version, introduces some innovations in terms of materials and design. An electroluminescent flexible film was in fact applied along the backbone and controlled by a switch inside the pocket, this will permit to increase the visibility in sea also in adverse weather conditions.
The next development of the electroluminescent film is the electroluminescent fabric, that is composed, like for the plastic film, by a layer of light emitting phosphor printed between two very thin electrodes and subsequently spread, following some special techniques, on a textile substrate. The obtained device has very interesting properties including a good brightness and durability together with a very high flexibility and versatility. It is possible, in fact, to customize its shape, dimension, colours, graphics effects and, choosing the most suitable textile support and its external coating, to obtain many special properties like flame resistant, waterproofness, washability, stain and abrasion resistance. Thanks to these enchanting peculiarities and to a collaboration with an American company, producer of these electroluminescent fabrics, Grado Zero Espace is studying the feasibility to integrate this technology into textile, interior design, automotive, tuning, sport and safe equipment sectors.
