Light sources and detectors are key components of countless technological devices on the market today. For instance, light emitting diodes (LEDs) are often used as a source of light in displays and ...

What Is A Light-Emitting Diode? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. LEDs function by converting electrical current into ...

LED lighting has largely replaced traditional incandescent bulbs and energy-saving lamps because it is more efficient and ...

Last August, the town of Irondequoit, N.Y., near Rochester, opened its $13 million, 37,800-sf public library. The entry lobby is illuminated by organic light-emitting diode (OLED) fixtures, one of the ...

Wilmington, Del.-based– DuPont has been awarded a $2.25 million grant from the U.S. Department of Energy (DOE) for a two-year project to develop a solid-state lighting (SSL) source using low-cost ...

This continuous LED is perfect for photographers and videographers who need a compact, constant light with an extra-long ...

Blue light is vital for light-emitting devices, lighting applications, as well as smartphone screens and large screen displays. However, it is challenging to develop efficient blue organic ...

The U.S. Department of Energy recently awarded $11.5 million to install light emitting diode lighting in parks, police stations, an airport runway, baseball fields and city buildings to promote energy ...

An LED and a semiconductor laser (or laser LED) work in essentially the same way, that is, light is emitted as electrons and holes combine, with emission wavelength dependent upon the materials used.

An upconversion organic light-emitting diode (OLED) based on a typical blue-fluorescence emitter achieves emission at an ultralow turn-on voltage of 1.47 V. The technology circumvents the traditional ...
