DOE Science Showcase - Light-emitting Diode (LED) Lighting Research

Light-emitting diode (LED) lighting is a type of solid-state lighting that uses a semiconductor to convert electricity to light. LED lighting products are beginning to appear in a wide variety of home, business, and industrial products such as holiday lighting, replacement bulbs for incandescent lamps, street lighting, outdoor area lighting and indoor ambient lighting. Over the past decade, LED technology research and development supported by the U.S. Department of Energy (DOE) has yielded impressive improvements in the cost, color performance, light output, efficacy, reliability, lifetime, and manufacturability of LED products and this upward trend is expected to continue.  Read about the latest DOE research, the technology behind LEDs, patents, field tests, and analyses of LEDs and associated devices in actual use in Dr. William Watson’s latest white paper In the OSTI collections: Light-emitting Diodes (LEDs).
