Researchers have demonstrated white, organic light-emitting diode (OLED) sources with the same efficiency as fluorescent light bulbs.
研究人员展示了白色有机发光二极管跟荧光灯泡有一样的效率。
These light sources also produce a blue-white light that is safer because it is closer to natural daylight.
这些光源也产生蓝白光是安全，因为它更接近自然光。
As one of the most promising light sources, white LED has many advantages, such as high luminous efficiency, high luminous intensity, long life period etc.
在强调节能减排的今天，白光LED因为具有发光强度大，效率高，体积小等优点而被视为最具潜力的光源之一。
