Experimental white LEDs were demonstrated in 2014 to produce 303 lumens per watt of electricity (lm/W); some can last up to 100,000 hours. Se mer 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. … Se mer In a light emitting diode, the recombination of electrons and electron holes in a semiconductor produces light (be it infrared, visible or … 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 cause a large change in current. Current through the LED must be … 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. Russian inventor Oleg Losev reported … 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 … Se mer

Nettet31. mai 2024 · Red + blue light is not superior to white light for plant growth. To the contrary, the LUE of red lettuce ‘Rouxai’ under warm-white light was at least 26% higher than under red + blue light when the blue fraction was at least 11%. It was 33–40% higher compared to red + blue light when the blue fraction was 33%.
