Txheej txheem cej luam ntawmLED teeb pom kev zoo
Txoj kev ua tau zoo ntawm LEDs yog ascribed rau lawv qhov txawv semiconductor cov ntaub ntawv thiab architecture. Nyob rau hauv sib piv rau incandescent qij, uas tsim lub teeb los ntawm cua sov ntawm filament, coj hloov hluav taws xob rau hauv lub teeb tam sim ntawd ntawm electroluminescence. Cov txheej txheem no eradicates lub zog ploj mus rau kev tsim cua, yog li no muab cov teeb ci ntau dua.
LEDs yog tsim los ntawm kev sib txuas ob ntau yam ntawm semiconductor muaju, thiab lwm yam doped nrog rau indium los yog arsenic, los tsim ib qho n-hom slicivike. Cov txheej txheem doping tsim ib qho kev sib tshuam uas pom tias cov ntawv tso cai tam sim no los ntws mus ib ke.
Thaum twg ib qho hluav taws xob uas haum tau muab tso hla cov kev sib tshuam, hluav taws xob los ntawm N-hom cheeb tsam tsiv teb tsaws chaw hauv cheeb tsam P-hom (tom ntej kev tsis ncaj ncees). Qhov no recombination emits lub zog raws li photons, tsim teeb. Cov zis tawm lub Hue yog kev sib txuas ntawm cov semiconductor lub zog band sib txawv thiab cov khoom siv doping ua haujlwm; Piv txwv li, koom nrog txhuas mus rau hauv Gallium Arsenide Diode tsim cov liab LED teeb.
Qhov zoo ntawmLED teeb pom kev zoo
LED teeb pom kev muab ntau cov txiaj ntsig uas tau nrawm nws ntau thoob plaws hauv cov kev siv ntau yam. Kev kawm tsis ntev los no los ntawm cov kws tshaj lij ntawm University of Michigan qhia tau tias LED ua haujlwm tau, muab 18%}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} pa fluchaniciency piv rau T8 fluorescent qij.
LEDs muaj lub neej ntev txog li 25, {}}}}}}}}}}}} lub sij hawm hloov pauv thiab hloov cov nqi. Lawv cov kev nkag siab zoo-lub xeev cov cim tau lees paub, ua rau lawv ua kom tsis txaus siab thiab muaj peev xwm ua kom muaj xwm txheej nyuaj siab.
LEDs muab cov xim zoo nkauj, ntau yam ntawm cov xim sib txawv, thiab sib txawv nrog cov khoom siv hluav taws xob tsawg, kev xaiv hnub ci zoo rau kev lag luam thiab sab nraum zoov siv.
Chronologess hlob zuj zus ntawmTeeb Emitting Diodes
Kev lag luam teeb pom kev zoo tau pib ua nws txoj kev hloov tshiab thib peb nrog cov leds dav dav, tom qab lub epochs ntawm incandescent teeb thiab fluorescent leeg. Kev hloov pauv tau yooj yim los ntawm kev nce qib hauv Electrolacescence, ib qho tshwm sim ua ntej los ntawm Henry Yauxej puag ncig xyoo 1907.
Kev nce qib tom ntej uas pom zoo olcompassed olcompassed oleg Losev kev tsim muaj ntawm thawj tus coj xyoo 1927; Txawm li cas los xij, nws yog Nick Holyak Jr. cov qauv pom ntawm thawj zaug pom pom-spectrum coj hauv 1962 ntawm cov cim taw qhia kev pib ntawm LED kev ua lag luam.
Thaum pib, LEDs tau txwv los ntawm qis luminous flux thiab monochromatic lub teeb, uas tabkaum lawv daim ntawv thov hauv General. Shuji Nakamura kev tsim muaj ntawm lub xiav coj tau daws cov kev cov nyom no los ntawm kev tsim cov teeb ci dawb thiab ntau cov xim kub.
Hauv 2000s, kev ua lag luam ntawm cov kab dawb ua rau lawv muaj kev sib xyaw ua ke hauv cov ntawv thov teeb pom kev zoo ntau yam. Qhov kev hloov pauv no txuas ntxiv thoob plaws xyoo 2010 nqis tiv rau kev txhim kho hauv kev ua tau zoo, luminosity, thiab txo nqi. Technology thev naus laus zis nyob rau hauv nws cov kev hloov kho, txhim kho kev ua tau zoo, thiab daim ntawv thov.
Tsis ntev los no kev hloov kho hauvLED Tshuab: Mitigating doop
Kev tshawb fawb luam tawm hauv Science Readies soj ntsuam cov kev ua haujlwm pheej yig hauv LED Technology, nyob rau qhov xwm txheej tshwm sim tshaj li qhov kev xav tau txawm hais tias nws xav txog hluav taws xob.
Cov kws tshawb nrhiav nthuav tawm cov nanoscale LED tsim suav nrog zinc oxide fins uas muaj peev xwm txhim kho hluav taws xob muaj peev xwm thiab txo cov khoom cuam tshuam hluav taws xob. Qhov no tau txhim kho LED LED kev ua kom pom tseeb txog qib 100 rau 1, {2}} lub sijhawm muaj hluav taws xob, nyob rau hauv sib piv rau 22 nanowatts feem ntau tsim los ntawm cov khoom siv submicron-me ntsis LEDs.
Qhov kev ua tiav no tau qhia txog kev txhim kho tshwj xeeb hauv kev txhim kho kom zoo dua, muaj peev xwm ua tau zoo dua thiab siv cov tshuab sib txuas lus, suav nrog kev sib txuas lus thev naus laus zis thiab tshuaj tua kab mob sib txuas lus.
Quantum DOT LED ntse ectigry Illumination system
Cov kws tshawb nrhiav ntawm University of Cambridge tau tsim cov quantum dot-based ntse cov kab ke uas muab cov xim dav dav ntawm kev customization ntawm kev customization tshaj tawm. Qhov kev tshawb pom tau nthuav tawm hauv kev sib txuas lus.
QD-LED System neeg ua haujlwm Lwm cov xim ua haujlwm ntxiv rau cov khoom ntsuab, liab, thiab xiav, yooj yim sawv cev ntawm nruab hnub. Nws tau ua tiav cov xim xim sib xyaw ntawm 2243K (liab) rau 920 xyoo ntawm 97, tshaj li 80 txog 91 cri ntau yam ntawm ntse ntse qhov muag teev.
Qhov kev tsim kho no muaj lub peev xwm ua kom pom kev zoo heev rau kev pom thiab lub zog ua tau los ntawm kev muab cov teeb pom kev zoo dua thiab hloov kho teeb pom kev zoo dua qub.
