基本解释

A variation of this approach uses small light-emitting diodes (LEDs) instead of reflective markers.
此方法的另一形式是运用可发光的二极管代替可反光的标志。
Another approach, organic light-emitting diode (OLED) technology, shows promise but is expensive and difficult to scale up.
另一种方式，是有机发光二极管技术，前途光明却价格昂贵，且难以大规模[生产]。
The lamps' small size makes them comparable to light-emitting diodes but the new lamp generates much brighter light than those semiconductor devices do.
凯若维森灯的小巧外形与发光的二极管相似，但前者比那种半导体装置发出的光更加明亮。

Light-emitting diodes are small glass lamps that use much less electricity than traditional bulbs and last much longer.
He began experimenting with light-emitting diodes, LEDs,at his laboratory at the University of Calgary in Alberta.

Light-emitting diodes--semiconductors that emit light when electricity passes through them--have been around since the 1960s.
