A new form of OLED (organic light emitting diode) has us salivating as much as the Luxim LIFI plasma arc lighting. We’ll let you read the entire post which we have reproduced with permission but when and if this technology makes it to market, we’ll be seeing color-accurate sunrises and sunsets over our reef tanks.
Scientists in Taiwan have developed an organic light-emitting diode (OLED) that closely mimics the color range produced by sunlight during different times of day and in different regions of the world. The color temperature ranges from 2300 to 8200K depending on the voltage applied to the device. Sunlight color temperatures range from 2500K in the morning, 5500K at noon (8000K in high-latitudes), and 3250K at dusk. According to the researchers, no other single lighting device can emit a daylight-like lighting curve with a range that covers the full spectrum of sunlight. In addition to their wide color range, the new OLEDs have a simple design consisting of layers only a few nanometers thick and emit high luminescence at relatively low applied voltages. The development scientists envision these new phosphorescent light sources replacing current incandescent, fluorescent, and even LED sources because of their enhanced efficiency, variable color temperature, and potential for flexibility. These new lights may have incredible potential for planted (or reef) aquarium use. Image credit: Jou, et al., PhysOrg.com.

!!!! Progression.
drooool…….
I really honestly think this is where lighting is going to end up for a while, until the next big breakthrough of course. OLEDs will be flexible, roll to roll printed, high CRI, more efficient than regular LEDs and I was researching OLEDs and a project in Europe is trying to get 100lumens/watt at about 100 euros per square meter. Not to mention that in about 10-15 years OLEDs are going to be in EVERYTHING.
A few more years and we could be purchasing our lighting by the foot! how amazing.
There are a few LED makers like Cree that are already boasting the same thing. The advantage is that they actually last a while… the biggest problem with OLED’s is their short lifespan. That is why the initial markets for OLED’s are cell-phones and other small electronics. Their was supposed to be a whole slew of OLED TV’s on the market by now (the picture they make when new is amazing), but they are still having longevity issues. I have my doubts about OLED’s and aquarium lighting considering the much longer lifespan they would need, and they currently cant even last long enough to justify being used in something that is as less frequently used as a TV.
… I suppose you could buy hundreds of cell phones to light your tank with…lol.
Of course right now OLEDs aren’t going to be the best when compared with even LEDs, which havent been around that long, OLEDs are just on the fringes of infancy. the OLED100 project that I was talking about wants to have OLEDs that last 100,000 hours. That beats even the LEDs that Cree are making that only have a 50,000 life span. Phillips, GE, Samsung, they are all pouring money into OLEDs right now. The problem is that with regular LEDs they are pretty much based on the same market as silicon and CPUs, this is why we are seeing LED increases at about the same time as we are seeing CPU increases because they are working off the same principle. OLEDs on the other hand are just that. Organic molecules, you have one subunit that you can add other subunits onto in order to change the color output of the voltage that is beeing supplied to it so it would make for much easier quality control. Like I said in the end I think OLEDs will have more advantages than LEDs once they have broken a few minor details.
OLED is an amazing technology. Its nothing like LED in the way they are formed. OLED lighting is like a panel. Google “phillips lumiblade”. I’d expect the effect of this technology to be more like a fluorescent fixture of some kind.
