Light-emitting diode (LED) ke mohloli oa lebone la semiconductor tse etellang pele tse peli. Ke pn-junction diode, e hlahisang leseli ha e kentsoe.
Li na le thuso haholo bakeng sa libenche tsa mosebetsi, merero ea ho haha mabone, esita le ka ho toba lisebelisoa tsa motlakase hobane li sebelisa matla a fokolang 'me li ntša mohloli o matla le o tsitsitseng oa leseli.
Ke sona seo u se batlang ha u khantša morero, leseli le sa thothomeleng 'me le ka tsamaisoa habonolo, ho tloha beteri kapa sesebelisoa ka boeona.
Ha motlakase o loketseng o sebelisoa ho li-leto, li-electrone li ka kopana hape le masoba a elektronike ka har'a sesebelisoa, ho ntša matla ka mokhoa oa photon.
Phello ena e bitsoa electroluminescence, 'me' mala oa leseli (o tsamaellanang le matla a photon) o khethoa ke lekhalo la sehlopha sa matla sa semiconductor.
LED hangata e nyane sebakeng (ka tlase ho 1 mm2) mme likarolo tse kopaneng tsa optical li ka sebelisoa ho bopa mohlala oa eona oa mahlaseli.
E ne e bonahala e le lisebelisoa tsa elektronike tse sebetsang ka 1962, li-LED tsa khale li ile tsa ntša leseli le tlase la infrared.
Li-LED tsa infrared li ntse li sebelisoa khafetsa e le lisebelisoa tse tsamaisang li-circuits tse laolang remoutu, joalo ka tse ho li-remote control bakeng sa mefuta e mengata e fapaneng ea lisebelisoa tsa elektroniki tsa bareki.
Li-LED tsa pele tse bonahalang-tse khanyang le tsona li ne li le matla a tlaase, 'me li lekanyelitsoe ho khubelu. Li-LED tsa morao-rao li fumaneha ho pholletsa le maqhubu a bonahalang, ultraviolet, le infrared wavelengths, ka khanya e phahameng haholo.
Li-LED tsa pele li ne li atisa ho sebelisoa e le mabone a bontšang lisebelisoa tsa elektronike, ho nkela li-bulbs tse nyenyane tsa incandescent sebaka.
Haufinyane li ile tsa kenngoa ka har'a lipalo tsa lipalo ka mokhoa oa lipontšo tsa likarolo tse supileng, 'me li ne li atisa ho bonoa lioacheng tsa digital.
Lintlafatso tsa morao-rao tsa li-LED li lumella hore li sebelisoe ho khantša tikoloho le mesebetsi.
Li-LED li na le melemo e mengata ho feta mehloli ea leseli la incandescent ho kenyelletsa tšebeliso e tlase ea matla, nako e telele ea bophelo, matla a ntlafetseng a 'mele, boholo bo fokolang, le ho fetoha ka potlako.
Hona joale li-diode tse ntšang khanya li sebelisoa mefuteng e fapaneng ea mabone a lifofane, mabone a likoloi, lipapatso, mabone a akaretsang, matšoao a sephethephethe le mabone a lik'hamera.
Leha ho le joalo, li-LED tse matla ka ho lekaneng bakeng sa mabone a phaposi li ntse li le theko e boima, 'me li hloka taolo e nepahetseng ea hajoale le ea mocheso ho feta mehloli ea lebone la compact fluorescent e ka bapisoang.
Li-LED li lumelletse mongolo o mocha, lipontšo tsa video, le li-sensor hore li ntlafatsoe, athe litekanyetso tsa tsona tse phahameng tsa ho fetoha li boetse li le molemo ho theknoloji e tsoetseng pele ea puisano.
Ke Joost Nusselder, mothehi oa Tools Doctor, content marketer, le ntate. Ke rata ho leka lisebelisoa tse ncha, 'me hammoho le sehlopha sa ka esale ke theha lingoloa tse tebileng tsa blog ho tloha 2016 ho thusa babali ba tšepahalang ka lisebelisoa le malebela a ho qapa.
