Glødelamper hadde et lysutbytte på litt under 15 lumen/watt. Halogenpærer ligger 30 til 40 prosent høyere. Utviklingen av LED nærmer seg nå 100 lumen/watt, slik at dette er langt mer effektivt for belysning enn tradisjonelle lyskilder. hero and hero alts

A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required … Se mer Discoveries and early devices Electroluminescence as a phenomenon was discovered in 1907 by the English experimenter H. J. Round of Marconi Labs, using a crystal of silicon carbide and a cat's-whisker detector. … Se mer By selection of different semiconductor materials, single-color LEDs can be made that emit light in a narrow band of wavelengths from near-infrared through the visible spectrum … Se mer LEDs are made in different packages for different applications. A single or a few LED junctions may be packed in one miniature device for use as an indicator or pilot lamp. An LED array may include controlling circuits within the same package, which may … Se mer In a light emitting diode, the recombination of electrons and electron holes in a semiconductor produces light (be it infrared, visible or UV), a process called "electroluminescence". The wavelength of the light depends on the energy band gap of the semiconductors … Se mer In an organic light-emitting diode (OLED), the electroluminescent material composing the emissive layer of the diode is an organic compound. The organic material is electrically conductive … Se mer Power sources The current in an LED or other diodes rises exponentially with the applied voltage (see Shockley diode equation), so a small change in voltage can … Se mer LED uses fall into five major categories: • Visual signals where light goes more or less directly from the source to the human eye, to convey a … Se mer NettetLED [ ĕl′ē-dē ′, lĕd ] Short for light-emitting diode.
