有机发光二极管更接近主流照明
发光二极管是一种正在迅速成熟的技术，正在大举进军传统的照明市场。然而，这并不是城里唯一的新照明技术。有机发光二极管（OLED）现在被认为是一些建筑照明应用的一个选择，因为它是一种显示技术，在没有背光的情况下提供鲜艳的色彩。
有机电致发光器件不同于传统的发光二极管，因为电致发光不是来自半导体结，而是由有机化合物膜产生的。这使得有机发光二极管易于制造成大的，轻的，甚至是柔性的面板。然而，尽管与传统的LED相比，一些关键优势，这些设备还没有作为商业照明选项，主要是由于低效率和高成本相比，固态光源。
本文介绍了当今商业照明OLED的性能，并将其与现有技术进行了比较，包括LED。
An alternaTIve to LEDs
LEDs are sTIll a relaTIvely new technology， but hundreds of millions of dollars of development has seen it move into the mainstream. LEDs are compact， energy-efficient products that promise long life and lighTIng topologies that were previously impossible with fragile and bulky incandescent bulbs and fluorescent tubes.
Despite their obvious appeal， LEDs do have some drawbacks. Chief among these is sensitivity to raised operating temperature， which affects efficacy， color， and longevity. Another key drawback is current sensitivity. The current driving the LED must be maintained in a very narrow range; too low and the device fails to illuminate properly， too high and efficiency tails off rapidly.
