Product Application:
An infrared light-emitting diode (LED) is not used to light up screens and monitors the way other LEDs are; instead, it is often used for non-visual applications and for nighttime illumination. The application of an infrared LED depends on its nanometers (nm), or its wavelength, with the common usage being between 808nm and 940nm. Infrared LED devices are used in everyday life in TV remote controllers and automated card readers. The use of infrared LEDs can be separated into two types: direct and reflecting, and the manner in which the infrared LED and the receiving diode interact determines the LED's uses.
Fit-tarf t'isfel tal-frekwenza infra-aħmar, 808nm, LEDs infra-aħmar huma komunement użati f'applikazzjonijiet mhux -viżwali iżda jinstabu wkoll f'kameras tas-sigurtà. Lejżers-stat solidu u lejżers mediċi u apparat jiffunzjonaw b'din il-frekwenza infra-aħmar. L-illuminazzjoni infra-aħmar hija wkoll possibbli hawnhekk, li tippermetti lill-kameras tas-sigurtà jiffunzjonaw bil-lejl mingħajr dawl, għalkemm l-immaġni li jaqbdu hija ġeneralment b'-riżoluzzjoni baxxa. F'830nm, dan id-dawl infra-aħmar jintuża għal qarrejja tal-karti awtomatizzati f'subways u lukandi.
Bejn 840nm u 870nm, LEDs infra-aħmar jinstabu b'mod aktar komuni f'applikazzjonijiet viżwali. Dawn l-LEDs jintużaw f'kameras li ma jgħaddix ilma minnhom u kemm fil-kameras tas-sigurtà bi nhar kif ukoll bil-lejl fil-ħwienet u f'salib it-toroq. L-applikazzjoni mhux-viżiva f'dan il-wavelength tidher l-aktar f'sistemi ta' allarm siekta u telefowns tal-bieb.
L-ogħla sinjal LED infrared, 940nm, huwa dak li l-konsumaturi jużaw l-aktar spiss. Dan huwa l-LED responsabbli għall-funzjonalità tal-kontrolli mill-bogħod, inklużi dawk użati ma 'televiżjonijiet u plejers tad-diska tal-vidjo diġitali (DVD). Kontrolluri tal-logħob mingħajr fili jappartjenu wkoll għal din il-lista. Kwalunkwe apparat li juża kontroll remot b'teknoloġija infrared juża dan is-sinjal LED.
Biex taħdem LED infra-aħmar, wieħed minn żewġ metodi ta 'kontroll irid jiġi impjegat. Id-dawl dirett għandu l-LED li jarmi fl-apparat ta 'kontroll, u d-dijodu li jirċievi fl-apparat li jirċievi, u l-apparat li jarmi m'għandux għalfejn jipponta direttament lejn l-apparat li jirċievi. Dan il-metodu huwa l-metodu modern; huwa aktar konvenjenti għall-użu, minħabba li l-utent m'għandux għalfejn jindika direttament il-kontrollur lejn l-apparat.
An Infrared light-emitting diode (IR LED) is a special purpose LED emitting infrared rays ranging from 700 nm to 1 mm wavelength. Different IR LEDs may produce infrared light of differing wavelengths, just like different LEDs produce light of different colors
L-LEDs IR huma ġeneralment magħmula minn arsenide tal-gallju jew arsenur tal-gallju tal-aluminju. Flimkien mar-riċevituri IR, dawn huma komunement użati bħala sensuri.
The appearance of IR LED is same as a common LED. Since the human eye cannot see the infrared radiations, it is not possible for a person to identify if an IR LED is working. A camera on a cell phone camera solves this problem. The IR rays from the IR LED in the circuit are shown in the camera.
An IR LED is a type of diode or simple semiconductor. Electric current is allowed to flow in only one direction in diodes. As the current flows, electrons fall from one part of the diode into holes on another part. In order to fall into these holes, the electrons must shed energy in the form of photons, which produce light.
Huwa meħtieġ li l-emissjoni mid-dijodu IR tiġi mmodulata biex tużaha f'applikazzjoni elettronika biex tipprevjeni triggering spurju. Il-modulazzjoni tagħmel is-sinjal mill-LED IR jispikka fuq il-ħoss. Dajowds infra-aħmar għandhom pakkett li huwa opak għad-dawl viżibbli iżda trasparenti għall-infra-aħmar. L-użu massiv ta 'LEDs IR f'kontrolli mill-bogħod u sistemi ta' allarm tas-sigurtà naqqas drastikament l-ipprezzar tad-dijodi IR fis-suq.
