Researchers Create New Cheap, Shatterproof, Plastic Light Bulbs 296

hattig writes "US researchers say they have developed a new type of lighting that could replace fluorescent bulbs. The new light source is called field-induced polymer electroluminescent (Fipel) technology. It is made from three layers of white-emitting polymer that contain a small volume of nanomaterials that glow when electric current is passed through them. The developer is promising cheap, hard-to-break, mercury-free, highly efficient bulbs from 2013."

          I see a flicker from florescent lights. CFLs and bar style. Bugs the crap out of me. Had to switch to torchiere style lights so it at least bounces off the ceiling first. They cause me headaches over a long period of time. I switched a lot of my lights I use most commonly to LEDs around the house and it helped. Point being, sometimes people don't hate something because it's different. Haven't bought an incandescent bulb in years, because I'm energy conscious, but I can see where others might not want to subject themselves to headaches because someone else says they can't buy the bulbs they like.

            For TL tubes, you can get dimmable electronic ballasts which convert the power grid frequency to something in the 10 kHz range. I have one hanging over the dining room table, and it's wonderfully silent and flicker-free. The only drawback is the price (~$40).

            Only the oldest CFLs used a magnetic ballast at line frequency; virtually all on the market today use a high frequency (> 10 kHz) switching supply to in order to reduce the size and cost of the transformer.
            If your CFLs are perceptibly flickering, it is due to some other device affecting the power quality (large appliance motors, usually).
            Older and "bargain" tube-style fluorescent fixtures use magnetic ballasts, so it isn't uncommon for those to flicker.
            Sometimes perceived flicker is due to vibration (jiggling eyeballs).
            View the light source through a moving electric fan blade.
            If you can see blade images (think wagon wheels in the movies), you have a magnetic ballast light source.
            I'm pretty sure that no human can perceive flicker faster than ~110 Hz.

          The bulb backlash is driven mostly by a political divide. The US is very much a two-faction country, politically - the liberals and the conservatives, represented by their respective political parties. Environmental causes have long been seen as a very liberal thing, so those on the conservative faction feel they are obliged to downplay the issue and oppose any solution.

          • I'm fiscally conservative, and see conservation as a smart financial move. However, it has to be practical as well. How will these lights perform in cold weather? All my interior lights are CFL, but outdoors I've switched half of them back to higher-wattage incandescents than before (because the lower wattage units are not as available now) because once the temperature falls below 55F, CFLs take a very long time to reach full brightness.

            • You should try some different bulbs... I live in the Denver area, and I have a CFL on my porchlight that lights up instantly every time, no matter how cold it is. Different brands can make a lot more difference than they should.

            Funny enough, environmental causes USED TO BE a conservative position. The EPA, for example, happened on Nixon's watch. Of course, neither Nixon nor Reagan would survive a Republican primary today. Today's US conservative movement might be more accurately called "reactionary", they're so far to the right. A US liberal would be center-right in Europe.

          • The Democrats in the United States are actually centrists by the standards of most countries. The liberals in America don't have any political power while their far-right counterparts have completely taken over the Republican Party. Look at the "socialist" health care plan passed by the Democrats. The heart of the plan is the very conservative idea of individual responsibilityâ"the individual mandate was a conservative idea until the Democrats embraced it, at which point it suddenly became a socialist plot against Americans. A true liberal would have pushed for a one-payer system.

            And so it goes.

            Not really. The National Park system was vastly expanded by a Republican, Teddy Roosevelt. The Environmental Protection Agency was established by a Republican, Richard Nixon. Hunting organizations, whose members tend to lean right, do far more land conservation than any other type of private organizations.

            Certain environmental causes may seem liberal but that has more to do with a specific cause being politicized by liberals not because conservatives are inherently anti-environment. Regrettably both part

      The funny thing about florescent tubes is how recently they became 'controversial'. Essentially all the R&D was in place for conventional hot-cathode tubes by the late 30s, and they were owning the commercial, industrial, and other cost-sensitive bulk sectors. And these were the good shit: Mercury, beryllium, the kind of stuff that wasn't good for you even in the '50s, back when smoking and liquid lunches were doctor-approved...

      Once they became symbols of tyrannical envirofascist totalitarianism, though, you'd have thought that they'd started filling the things with nerve gas.(Amusingly, the bulk commercial/institutional users still don't give a fuck. Just stay after hours at any giant cube farm or similar and you'll see the janitors shoving around garbage cans full of old tubes, half of them broken, without the slightest concern...)

      • knowledge and available alternatives (or the possibility thereof) change opinions.

        As for the commercial/institutional users - they tend to shave every penny they can, regardless of the health and safety of their employees, so how's that say anything other than "it's cheap and not illegal, or enforced to the point where the illegality matters"?

      • It's more than the symbolism. A few things here:

        * At least for some people, the CFLs are noticeably worse than the old tubes. Don't know why, but my husband gets headaches really quickly (we're talking about 2 minutes or so) under CFLs, but only finds the big ceiling lights to be sort of annoying (unless the ceiling lights are flickering, those are terrible).

LED's, though more pleasant to use, are marginally more efficient than CFL's, but not as efficient as a standard T8 florescent lamp (100 Lumens per Watt). Polymer based Electro Luminescence is not new; I am very interested in this efficiency they are talking about (which is painfully missing in the article, 5x more than what????)

    • If they're free of flicker and buzzing, are instant-on even below 55F, don't cost >$20 each, and are dimmable, I can't see anyone complaining.

      The big problem with banning incandescents is that in uninsulated basements, garages, and directly outdoors, CFLs are utterly worthless during the winter unless you plan on keeping the lights on 24/7 to maintain operating temperature - which completely defeats the purpose of high efficiency lighting.

      • Oh and one more thing: if they can cover the full color spectrum for proper color rendition and come in an actual white rather than "daylight" that makes everybody look ill or fugly yellow "soft white", they will be better than both CFL and LED lamps as well as incandescent for indoor purposes as well. :-)

    This is no longer needed. Some countries are phasing out even CFLs in favor of LEDs, for example China by 2016 won't allow sale of units over 15w. LEDs are already "shatter proof" and they don't carry any gases inside ("solid state").

    China will ban imports and sales of certain incandescent light bulbs starting October 2012 to encourage the use of alternative lighting sources such as light-emitting diodes (LEDs), with a 5-year plan of phasing-out incandescent light bulbs over 100 watts starting October 1, 2012, and gradually extend the ban to those over 15 watts on October 1, 2016. http://www.reuters.com/article/2011/11/05/us-china-light-bulbs-idUSTRE7A40MV20111105 [reuters.com]

    I have a couple of 10w (4x 2.5w pcs) LED flood lamps, they are too strong for direct lightning but pointing them up allows the light to reflect and diffuse back down nicely. They come up instantly and there is no flickering. Unfortunately they get a little too hot at the base because of the AC/DC transformer, thankfully i'm not enclosing them but overheating could be a problem for others. Perhaps we should adopt some form of DC power distribution inside the house to keep away this conversion from the lamps (and so many devices use DC anyway).

    Have you seen white LED street lamps? I have, and they work perfectly. They are also instant (instead of minutes) and the light lets you see many more colors at night. They are about 80w to 100w, instead of the usual 250w, and happen to last 10x more.

      LED lights are still pretty pricy, so if this technology can bring the cost of the lamps back down towards what incandescents cost, there's a use for it. Also, if it's actually "white-emitting" that will be a big improvement since CFLs ain't. Doubt it though.

      There have been long Slashdot discussions on DC. If I remember right, DC loses more power than AC on wire runs & has a higher shock risk. USB3 offers a good low-watt (4.5W max) DC power spec with power-saving modes. It requires "intelligent" devices to plug-in to request the power, which shouldn't be a problem nowadays.

    It seems to me a light source that is inherently flat would be ideal for a display backlight. It probably won't make them much thinner than they already are, but it could make them less complex to produce and possibly more repairable (by replacing aged backlights).

    Also, being able to attach these directly to walls and ceilings rather than mounting brackets or cutting holes for lamps would allow a wider placement of light sources than is currently practical. I'd probably have (at least) one on every wall plus some on the ceiling, to make sure that I could get an ideal spread of light sources for whatever work I might be doing.

I'd line the bottoms of shelves, and install panels on the ceilings and walls, under the edges of steps, under cupboards, even inside cupboards and closets and have light exactly where I need it. It seems that if this works, you can have light panels you can actually cut to size, which would allow for really creative, ultra-modern lighting installations. I would also install panels on the back of my televisions and monitors to provide ambient backlighting to increase the apparent contrast while watching movies.

      Imagine, the sort of panel lighting you see all the time in sci fi.

      It's been available since the 1960s. Electroluminescent sheets have been around for over 40 years. They're on the expensive side and light output per unit area is low, but they work fine. Some versions last for decades. (Some don't, which is a big problem for permanent installation.) They make good night lights and somewhat dim display backlights.

      Here's a A3 sized white electroluminescent sheet. [e-luminates.com] About 12" x 17", costs $125.

      So this is not a new thing. If the new version is a lot brighter or a lot cheaper, it might be useful. For now, it's another "nanotechnology" materials science article about an interesting lab phenomenon.
