subject: Hobbyists Enjoy The Illuminating Fun Of Electroluminescent Wire [print this page] Electroluminescent wire, or "EL wire" for short, is being used by an increasing number of electronics enthusiasts. EL wire is a thin copper wire coated in phosphor that glows when an alternating current flows through it.
It has a variety of uses and hobbyists looking to embark upon a funky and creative project are well aware of its qualities. Not only does it look cool, it"s also incredibly versatile. Electroluminescent wire is available in a number of different lengths and thicknesses. While it is thin, it is also very durable and has the flexibility to be manipulated to suit a variety of requirements.
How does it all work?
What"s inside EL wire that makes it glow and how does it all function to produce such a striking effect?
Essentially, the wire is made up of five components that all work together. A very fine wire is wound round the phosphor-coated copper core yet electrically isolated from it too. A clear PVC sleeve surrounds this apparatus and is in turn covered by another clear, coloured, fluorescent or transparent PVC version.
The process involved in creating light starts out when the alternating current is applied between the copper core and the thin wire surrounding it.
This gets the phosphor excited and emitting light. It is then the job of the additional dye within the clear sleeve to produce a multitude of different colours as the core itself is limited to its natural blue-green light.
Practically speaking
OK, so wire that lights up looks pretty funky. But what purpose does it actually serve? Well, it is essentially cosmetic. However, EL wire does have its own practical functions. For example, petrol heads have used EL wire to create smart looking displays under their car bonnets and on dashboards.
Meanwhile, hobbyists and clothing designers have also made use of the material to incorporate animated patterns on garments.
Using an EL sequencer, microcontroller and appropriate software, it"s possible to programme your own light show. You"ve probably seen those light-up children"s trainers. But an illuminated dress is something else.
If you"re still not convinced of EL wire"s practical qualities then remember this: it is also often used for safety and emergency lighting.
Getting the right kit
Want to discover the illuminating power of electroluminescent wire? You"ll need the right kit but thankfully it"s widely available. And it"s relatively cheap too.
The wire itself can be purchased in a variety of colours, lengths and thicknesses. Whole wire kits are also on the market. These sample packs will often contain an additional EL wire pocket inverter so that you can drive your project along.
You"ll also need that trusty sequencer. EL sequencers are essential for controlling on/off functions and to create the finished shapes and details you desire. By simply passing a charge between its two internal wires, electroluminescent wire creates an exciting display.
Its versatility and "cool factor" have been duly noted by both electronics enthusiasts and serious designers. They realise the power of harnessing EL wire and its suitability for when you want to complete a project that really stands out.
