Tsis ntev los no, Tsev Kawm Qib Siab Melbourne, Australia thiab Lawrence Berkeley National Laboratory tau sib koom tsim cov cuab yeej LED uas tuaj yeem kuaj pom cov zaub mov muaj kuab lom thiab roj cua ua rau tuag taus, thiab muaj lub luag haujlwm tshawb xyuas cov nqaij tsis zoo hauv lub tub yees thiab muab lus ceeb toom ntxov.
Cov kws tshawb fawb tau glued ib txheej ntawm cov xim dub phosphorous siv lead ua rau cov yas mos muag thiab khoov nws hauv qee txoj hauv kev, tso cai rau cov phosphor dub tso tawm lub teeb ntawm cov yoj sib txawv sib txawv, yog li tsim cov tunable infrared LED, uas ua rau lub cuab yeej muaj peev xwm tshawb pom muaj peev xwm ntawm yam khoom no. Qhov tshiab thev naus laus zis phosphorous dub no muaj cov yam ntxwv tshwj xeeb, thiab kev siv cov txheej nyias nyias ua rau cov ntawv thov hloov pauv tau yooj yim. Lub nthwv dej ntawm lub teeb tso tawm los ntawm cov phosphor dub tuaj yeem ua rau LED kho nyob hauv nruab nrab qhov nruab nrab ntawm qhov muag.
Ib qho tseem ceeb, lub cuab yeej tuaj yeem tso rau ntawm lub dav hlau me me vim nws qhov ua tau zoo tshaj plaws thiab lub teeb ci, ua rau cov neeg tua hluav taws, cov miners, thiab cov tub rog muaj kev nyab xeeb thiab tuaj yeem txheeb xyuas cov pa roj hauv qhov chaw nyab xeeb.
Qhov kev tshawb fawb no tau hloov kho ntxiv cov cuab yeej siv thev naus laus zis, txo tus nqi tsim khoom ntawm cov cuab yeej kuaj pom, thiab tseem nthuav dav cov ntawv thov ntawm LEDs, muab kev tshawb fawb txog yav tom ntej rau kev tshawb fawb thiab kev txhim kho cov cuab yeej ntsuas tshiab thiab ntsuas tshiab, thiab cov cuab yeej ntse yuav tsum ua neeg ntse dua
