Re: Paper thin LED

Pretty amazing stuff.

Hopefully this won't become dirt-cheap though. Otherwise, I can easily forsee it being used on every wrapper and package in every store. Or worse - those ads you get in the mail .

Re: Paper thin LED

Wonder when they will start using these in Tv's

Re: Paper thin LED

i saw that in japan 3 years ago, they where making lampshades & stuff with it.
no idea on price, lifespan or availability though.

Re: Paper thin LED

How about covering your ceiling with it? It might eliminate having to have lights all over the house. It could at least be a night light for hallways if nothing else.

Re: Paper thin LED

what if it costs 100$ per sq-meter ?
it may have a useable lifespan of 1year.

too many questions.

[rhomanski]

Re: Paper thin LED

No price, but I think it said a lifespan of twenty years.

Re: Paper thin LED

20 years continuous, or 20 years of 2 hours per day?
that's a labelling scam used on cfl lamps btw.

Re: Paper thin LED

It compared it to a led bulb. So I guess 5 years max continuous?

Re: Paper thin LED

led bulbs have a heatsink.

Re: Paper thin LED

You mean an attempted heatsink lol, copper trace doesn't work that well as we all know.

Re: Paper thin LED

not in tv's - with a bayonette or screw cap

Re: Paper thin LED

Lol yeah, even still the Leds on them are dying just as fast lol

Re: Paper thin LED

the philips ones are said to be very good.

[ReeceyBurger123]

Re: Paper thin LED

Actually yes, they have a grounded heatsink on the outside of the case, must work well tbh others are shit tbh.

I remember old Popular Science magazine talking how EL panels were out and going to revolutionize your home.
Walls were to be covered with super thin EL lighting, and you could control the color by varying frequency. 50,000 hr lifetime.
I guess that didn't pan out.

well you could make the house glow like a cave in lord-of-the-rings for 500Hours.

I doubt they can do even that.
Maybe 20 years if you never use it.

That's why I'm still using good old incandescent bulbs here, along with halogen (mostly GU10 and the long ones). Have quite a stash of the incandescent bulbs. Don't think I'll run out for at least another 10 years. They seem to last quite a while.

Well, on that note, I wonder what the efficiency of EL wire is. I did a brief search online right now, and I found nothing... or at least not anything with numbers. Just statements that it is "very efficient" (whatever that means, lol ).

I remember from one of our general EE classes in university, we learned that incandescent bulb had only around 5% efficiency, while LED and fluorescent lightning around 10-15% max. So where that "very efficient" EL wire fits in, I have no clue.
