Challenging LED

摘要

As performance increases and costs decline, light-emitting diode (LED) lighting is poised to become the predominant light source in the United States. Meanwhile, adoption of integrated advanced lighting controls continues to grow. Now, the question becomes whether another light source could achieve a level of value to challenge LED in general lighting. To do so, it would have to justify significant investments needed to develop it. Several novel technologies are in development or being commercialized. Some promise to extend the LED while others, such as organic LED and plasma, could challenge it alongside other sources.
