Hello Group,


i like to know what the product name of the flat bendebable glowing
panels is called.

i saw it on Light + Building in Frankfurt 2002 they where glowing and
it was possible to get it in different colours.

Where can i get it?



Best regards

The Ceelite is a form of electroluminescent panel. Have you
contacted CeeLite so see how sharp a bend they can make?

You may also want to take a look at OLED's from Universal
Display. http://www.universaldisplay.com/ They make some
very thin displays that are already being used in automobile
radios and cell phones.

Usual gotchas with EL, its not very bright, it has a finite lifespan,
harder its driven brighter it is but shorter it lives, it dims out in
patches when nearing end of life.

As its a sandwich construction with a transparent front electrode
bending in a sharp fold probably won`t work.

Think its DuPont make a screenprintable EL system maybe be able to
print a 90 degree butt joint on to a backing.

As Vic has pointed out OLED may be worth investigating as well.

There's another technology that can give you a flexible flat panel of light.
It involves plastic layers with optics such that the light makes a 90 degree
turn and comes out the surface. The light source is a linear fluorescent
lamp (small diameter such as a T2) or a row of LEDs edge lighting the
material.

It's cool stuff, but I haven't seen anything but samples and I don't recall
the manufacturer. Maybe someone else remembers.

I saw a similar technology in use way back in the late
1960's. I was attending a conference in Miami and each of
the rooms used for presentations had a portable board
perhaps 6 feet wide by 4 feet high that was made of a solid
clear plastic. The plastic was edge lit, probably with a
fluorescent lamp. The back side of the clear plastic was
placed against a dark material and the front side faced the
audience. Due to internal reflection, very little light
escaped from the front surface. Special crayons were used to
write on the front surface. They changed the index of
refraction and allowed light to escape. The effect was
dramatic. In a dark room the writing appeared to glow yellow
or red or whatever color crayon was used. The high contrast
between the glowing letters and the dark board made these
boards easier to read than any board I have seen since in a
conference setting - other than the new electronic "white"
boards that detect and then project anything written with a
special stylus.

These were popular as menu boards here for a while. They use standard
chinagraph pencils.

it's el advertisement or el backlight,for el advertisement,the el panel can flash in different ways just controlled by el inverter,it's the good lightbox materials.
