i wonder, will they do a kind of household lighting where you paint a coating on the cieling, (with no light fixture) and then you put a flow of electricity in it, and it lights up pretty bright? liek a light emmitting coating? (LEC, lol) is it possible, my dad said lighting in houses would be that way sometime in the future... hmm

Zero 88 Lighting Controls Rule!

GE has come out with something almost like that, crazy stuff hunh? Maybe someone could post the link, a few other members know about this too and I remember seeing this topic in a previous post.....

The future of street lighting is Induction, not nasty HPS lights or cr@ppy LED lights! Preheat CFL's should make a comeback!

I do not know any product close to what you mention, but let's speculate: If it should be applied by "painting" technology, it should form a layer of homogenous material. The only way to power such material by electricity would be applying electrical field parallel with the ceiling by two electrodes placed on top of opposite walls or by placing many thin parallel wires over whole ceiling surface, connecting all odd and all even ones, yielding two "lamp" terminals. Assume such "lamp" would require input power in tens of W (assume ~100lm total and efficacy about a CFL at least) on currents well below 0.1A for two electrode and 1A for "brushed" electrode design I would see three drawbacks: - There would be "open" electric conductors on the whole ceiling, with or high voltage or with short current capability. Te first would be then shock hazard, the second fire hazard (when it get's locally shorted). - As each room is unique at least by it's dimensions, such lamp would require ballast capable to adopt to actual "lamp" size. - Properties of such painting layer would strongly depend on it's thickness and predictability of them on the underlying surface smoothness. The first would yield to difficulties to apply such paint, the second would yield to plain, smooth ceiling surface, without any plastic texture, what would cause very sterile, unnatural look.

I think you are referring to the wall-paper OLEDs. GE has an article on it. The light from it will be so diffuse it would look weird than what it would look like under a single point of light. This test can be done by lighting the ceiling with a flood light. I have done this and it looked weird. (Don't have a flood light but used a strong flashlight.) I would suggest GE make a variable color wall-paper and allows you to choose where the light will come from and how big it is. (Programmable on a computer.) Mebbe program a sky view with clouds or stars. The possibilities are endless!

Why I like LEDs on top of other lighting tech? LEDs = Upgrade 95% of the applications. (That is if you avoid eBay's LEDs).
LED brainwash? No, people uses them cuz they work well for them.

Hmm, i wonder when they will make roads have the same kind of thing for the lines. like they light up, where there is no need for streetlights. only in big places where they NEED lights like that.
and heck, if roads turn to be lighteds that way, we could keep lots of old HID lights! lol

Not possible. Roads are too harsh for the thin OLEDs. Also too expensive and time consuming to install them. (Have to wire them up somehow.)

I think this would be the only possibility to get high enough luminous flux from OLED technology for general lighting, as high temperature, so high density operation would be out of reach from organic materials. But as i wrote, when powered OFF, it would look very sterile, when applied to large areas, not much comfortable to live there. And it should be on large area for required luminous flux.
