I love that dress! Great way to think outside the grid! Going to have to pass this photo onto my girlfriend.
I'm working on about 4 Tron Legacy costumes at the moment (Daft Punk, Flynn comic version, and CLU in robes). I haven't had the time to read every page of this thread, but I feel I'm up-to-dateish on what's been happening here having read a little bit each day. Now there's a lot of EL this and EL that being tossed around, not to mention Light Tape and so on. Can you elaborate a bit more on the EL Film? Is it loose and flexible? Or is it rigid? I did a google search just now and it is either trying to find spanish pages on movies (because of the "el") or its just general pages on electroluminesence. Care to share your source as well?
I'll echo the question about EL Film. Even searching electroluminecence Film got me no where
this is an over-generalized glossed-over attempt at an explanation just off the top of my head:
first off, i might use the terms sheet, panel, or film interchageably. and, i might use the term tape, strip, or panel interchangeably too, depending on the context.
e.l. aka electroluminescent implies applying electricity (electro) to emit light (luminescent). it comes in sheets/film and 'tape' strips, as well as wire.
light tape is a brand of el tape. it's stiff because they cover the electroluminescent strips in thick laminate, but is flexible enough to bend and curl to a certain limit.
all these consumer-available electroluminescent products have a coat of phospor that lights up when you apply an alternating current to it. the proper inverters are necessary because they convert a batttery's dc output into ac that is applied to the phosphor. when a current is passed across the electrodes, it lights up the phosphor -emitting the glow.
drivers/inverters vary in power with respect to the square inch of surface of e.l. you are applying it to -which could be the reason if you get a dimmer than desired result. a more powerful inverter might be needed. el wire has the least demand out of the inverter with regards to distance.
in other words & hypothetically, you can use an inverter to power 35 feet of wire. the same inverter might struggle on 2 square feet of el sheet.
e.l. in general eventually gets dim first before they die out. that's the trade-off with attempting to get maximum brightness out of the e.l.
i could be wrong about this but it is my understanding that electroluminescent sheets or tape can only bend a certain amount where a fold or a crease could create a short or not light up. the tolerances on this depend on the product and the resistance that is created fighting the flow of electrons.
wiring electroluminescent sheets, tape strips, wire (or what have you) have different methods and types of connectors which all try to minimize the resistance of the current flow in part to allow the inverters to not be worked as hard and to obtain the brightest glow possible out of them.
i've primarily used white sheets as large as a3 in size (bigger than your typical 8x11" el sheets). i've seen them as large as a2 for double the price.
specifically talking about the white luminescent colour (as opposed to other colours):
sheets not only vary in dimensions but also have wowo(white off/ white on) as well as powo (pink off/white on). powo is way more commonly found in more places such as glowhut.com. wowo is much harder for me to find but i do know they exist since i got mine from china
days after out tron costume meetup. some sort of wowo stuff appears to be what they used in the movie.
electroluminescent sheets are cutable into different shapes but the catch is you must include the conductive electrode ends so that you can place an electrode connector of your choice and wire it up to introduce the current. there's many ways to do this -from conductive copper tape syuzi uses, to crimp-on & solder connectors i use, to some special conductive silver actordiver uses, to metal screws compass72 uses, etc.
whatever shapes you create or cut out, it is essential that you find a way to seal the edges to protect the phosphor from moisture and other foreign contaminants. on tron legacy, you see the black outlines on the lighted patterns, which i assume protect the edges of their e.l. panel.
also, there's split electrode versus parallel electrode. split is very common in light tape, where you might see a thin line down the middle. parallel electrode has the conductive material where you apply the power on the edges of the material and does not contain that line down the middle. both these types of electrodes exist in tape and sheet products.
basically it comes down to the shape of the material
electroluminescent sheets/panels/film -cutable flat 2d shapes
electrouminescent tape/light tape/ el strips -cutable, flat 2d strips
electroluminescent wire - cheaper & runs longer distances but in 1d or wire form as opposed to flat shapes.
i hope this doesn't confuse anybody, and hopefully this brings some things into a sort of perspective.
