Ib lub kiv puag ncig hauv hluav taws xob, hluav taws xob, hluav taws xob thiab hluav taws xob tsis muaj zog tuaj rau kev lag luam thiab vaj tse, raws li daim ntawv ceeb toom tshwj xeeb tshaj tawm ntawm Optics Express , Optical Society (OSA) qhib phau ntawv journal.
Daim ntawv hais txog lub neej yav tom ntej ntawm lub teeb pom-ib lub neej yav tom ntej nrog kev siv lub teeb taws emitting diodes (LEDs), uas muaj ib tug xov tooj ntawm cov kev pom tseeb thiab hloov maj mam ua dua cov teeb qij.
"Peb nyob ntawm lub caij nyoog ntawm lub kiv puag ncig," hais tias daim ntawv sau ntawv loj hlob E. Fred Schubert, xib fwb ntawm hluav taws xob engineering thiab physics ntawm Rensselaer Polytechnic lub koom haum hauv Troy, NY. "Muaj ntau lub caij nyoog zoo uas qhib nrog LED teeb pom kev zoo."
LEDs muaj ntau rugged, zoo li ib yam dab tsi los ze zog rau cov tawv yas tshaj nyias khob. Lawv kuj yog ntau dua thaj suab zoo, vim lawv cov khoom siv tsis muaj tshuaj lom neeg xws li mercury.
Ua ib qho kev hloov rau cov teeb pom kev zoo ntawm lub teeb pom kev zoo, LED teeb muaj kev txuag hluav taws xob ntau. Lawv tuaj yeem ua 2,000 feem pua ntau tshaj qhov qij qhov muag qauj muag thiab 500 feem pua ntau dua li cov qhov muag teeb ntawm lub qhov ncauj. Schubert kwv yees hais tias kev siv ntau tshaj li ntawm 10 xyoo yuav txuag tau ntau tshaj li ntawm $ 1 trillion nyob rau hauv cov nqi hluav taws xob , tshem tawm qhov kev xav tau ze li ntawm ib billions ntawm cov roj ntau tshaj 10 xyoo, thiab ua rau txo qis hauv cov pa carbon dioxide, feem ntau cov tsev cog khoom roj.
Tag nrho cov txiaj ntsig zoo ua rau cov teeb pom kev zoo zoo ntawm LEDs, hais tias Schubert, ntxiv tias qhov no yog vim li cas thiaj li tau nthuav tawm qhov kev lag luam tshiab zoo tshaj, uas yog nce zuj zus tuaj. Txawm li cas los, nws ntxiv, qhov tseeb muaj peev xwm ntawm cov teeb pom kev zoo hauv cov lus dag hauv lawv lub peev xwm los hloov ua-tsis yog siv lub teeb pom kev zoo dua.
"Hloov yog qhov zoo," hais Schubert. "Tiam sis peb yuav tsum tau saib dhau qhov kev hloov chaw txawb kom pom qhov tseeb ntawm cov teeb LED." Schubert cia siab tias ib hnub thaum lub teeb hloov pauv txoj hauv kev rau lub teeb ci ntsa iab uas tswj tsis tau lub teeb ci xwb, tab sis nws cov xim kub thiab Hawj. Lub teeb spectra yuav yog kev cai-rau txhua lub wavelengths, txuam lub hnub lub teeb zoo thiab sib txawv ntawm cov yeeb yam raws li lub sijhawm ntawm hnub, piv txwv. Qhov no yuav ua rau sab hauv kev ua liaj ua teb thiab pab cov neeg ua hauj lwm yav hmo ntuj thiab cov neeg uas muaj dav hlau lag luam. Kev siv lub teeb ntsuab tuaj ntawm LEDs kuj tseem tuaj yeem txhim kho computer cov lus qhia thiab txo qhov kaj ntawm lub tsheb teeb.
Nyob rau hauv nws tsab xov xwm, Schubert lays tawm li cas yav tom ntej, "ntse" lub teeb ci , yuav ua kom muaj lub peev xwm loj ntawm LEDs.
