EL film
|
Electroluminescent films (EL film for short)
are an extremely flat type of light-emitting film. As with a capacitor, there is a layer of phosphorous particles located between two electrodes. When AC voltage is applied to the electrodes an electrical field is generated over the phosphorous and this causes it to emit light.

EL film is characterised by its versatility
Depending on requirements, our in-house EL film production department can create products capable of partial illumination or full illumination at our internal screen printing shop.
 EL film manufacturing process
|
|
EL illuminants are cold light sources
and emit practically no heat. They can be operated at voltages of between 40 V and 240 V and frequencies of between 50 Hz and 10 kHz.

The advantages of EL film
•
|
Very flat (approx. 0.2 mm, can be integrated into membrane keyboards/keypads)
|
•
|
Flexibles material (you can bend it) |
•
|
Low current consumption (at 110 V/400 Hz, approx. 0.15 mA without inverter) |
•
|
Low heat emission (approx. 1°C above ambient temperature) |
•
|
Extremely robust and highly resistant to vibrations and shocks |
•
|
Soft monochrome light (backlighting of displays) |
|
Fields of application
•
|
Backlighting of membrane keyboards/keypads and LCDs |
•
|
Instrument lighting |
•
|
Emergency or night lamps |
•
