Electroluminescent (EL) sheets are light-weight, flexible lighting.  Knema.com offers stock electroluminescent material available in a bluish-white light (when on).  Several panel sizes are stocked, custom sizes, shapes, and colors are available on request. 

Possible uses include signs, cove lighting (architectural lighting), floors, furniture, retail displays, lighted shelves, back-lighting electronic displays, theatrical costumes, emergency lighting, egress and pathway lighting.

  • Custom size and shape are available
  • Not affected by vibration
  • Does not burn out suddenly
  • Very low power consumption
  • Can be cut
  • Continues to operate, even if punctured
  • Approximately 0.020” thick

 

Electroluminescent (EL) material is offered in two types. One being Parallel Electrode, sometimes called an EL panel. This type of EL material does not have a center line and would be a good source for back-lighting signs and artwork. The second type of EL material is Split Electrode, a long and narrow or long wide electroluminescent strip. The EL strip is available in lengths of up to several hundred feet and has a 1/100-inch center scribe line running the length of the strip. The split electrode material is a good backlight source for signs where a small centerline will not detract from your graphic or where long length strips are needed as accent or pathway lighting.

Whether called foil, strip, panel, film, sheet, or lamp, the electroluminescent products are the same. EL panels are thin (~0.5mm), flexible and weigh about 4 ounces per square foot. The panels we stock are WHITE when on, pink when off. Other colors are available as a special order item, a tooling charge and minimum order quantity will apply.

 

electroluminescent custom panel

Custom size and shapes are available. We will need a CAD file in the DWG
format to quote and manufacture a custom size and shape EL panel.

Regarding panel appearance:

To make a white panel, manufacturers add a pink fluorescent dye to blue-green phosphor making the panel appear pink when “off” and bluish white when “on.” EL panels can have an acceptable white appearance when a graphic, printed on white film, is placed on the panel. However; some white areas in a graphic overlay can have a pink cast; this is caused by light reflecting off the graphic back onto the EL panel.

EL panels are manufactured with a process known as screen printing which gives a fairly even illuminated surface; It's not perfect, though and may not be appropriate for some optical calibration applications.


Electroluminescent Inverters

Inverters provide the required power to drive an EL panel. Electroluminescent panels require a voltage of approximately 100VAC or more, at a frequency of several hundred Hertz. We can provide inverters for your custom panel size. Click here to learn more.
