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.
