Nejilock has over 20 years of experience in Electroluminescent (EL) Light Technology. We have assisted many companies in setting up their own EL Factory. Your search ends here for expert guidance in crafting your Electroluminescent Light Panels!
Our comprehensive content will guide you through diverse techniques for producing EL Light Panels, detailing the necessary machinery and equipment, essential design principles, and intricate production procedures.
Discover the secrets behind Silkscreen Printed EL, Spray Painted EL, and Roll-to-Roll Slot-die-coated EL methods. Learn to design ink layers effectively and explore the machinery, inks, substrates, and inverters essential for creating stunning EL Lights.
Electroluminescent Light Technology is a non-thermal generation of light resulting from the application of an electric field to a substance.
The EL Light Panel is created by the following steps:
There are a few ways to make Electroluminescent Light Panels. We will explain them one by one, continue reading, or contact us for more information.
Flexible, made of Plastic.
Can be twisted, bent & cut into any shapes & sizes.
UV & Water Resistant.
Main Power or Battery Operated.
Low power consumption.
High visibility.
Light weight.
Non glaring.
Portable and easy to install.
In Electroluminescent Light Technology, the Screen Printing is the most commonly used method of making the EL Light Panels. The reasons must be the availability of skilled workers, machinery, and supporting industries.
The process is similar to printing posters or textiles, except EL requires understanding the function of different ink layers and handling printing inks with bigger particle sizes.
You start by designing the printing layer for the inks to create the positive films. There is a layer each for the Phosphor, Dielectric, and Silver Inks. The designs will then be cast into Positive Films in-house or by a contractor.
Next is to get ready the screens. I recommend you do the screens in-house to control quality and cost. Due to the particle size and viscosity of the EL Inks, the mesh size and tension strength are different from normal printing inks. We recommend 100T-40 (250 mesh/inch) for all three inks and >20N/cm tensile strength for the screens.
Indium Tin Oxide Coated PET (ITO) is the most common substrate for screen printing EL. Cut the ITO to size according to the design.
The Phosphor Ink has to be put on a roller a few hours before printing, this is to ensure the Phosphor particles and the binder are homogeneous.
Now, you are ready to print.
