Hauv ob xyoos no tom qab muaj kev sib kis, peb LED pleev daim iav xa tawm yog nyob ntawm txoj kev. Raws li cov chaw tsim khoom ntawm LED chav dej iav, peb lub tuam txhab tau yeej qhov kev lees paub thiab kev pom zoo ntawm cov neeg siv khoom hauv tsev thiab txawv teb chaws tom qab ntau tshaj 30 xyoo ntawm kev txhim kho thiab kev tsim kho tshiab hauv LED iav kev lag luam.
Xyoo no, nrog kev nce ntawm LED daim iav cov neeg siv khoom, peb lub tuam txhab kev txiav txim rau LED tsom iav tau dhau lawm thiab cov khoom xa tuaj tau ua haujlwm tsis khoom. Txog rau tam sim no, peb lub tuam txhab tau ua tiav ua tiav rau hauv 100 hom LED chav dej iav qauv xyoo no, ntau qhov ntau thiab tsawg thiab ua haujlwm pub rau cov neeg siv khoom kom muaj ntau qhov chaw xaiv. Thaum lub sij hawm tsim cov txheej txheem, peb hais kom siv cov iav zoo thiab cov khoom siv, ua ke nrog kev tswj cov txheej txheem nruj, ua rau peb cov iav LED ntawm qhov zoo tshaj plaws thiab kev pab lub neej ntev. Peb xav tias muaj kev ntseeg siab thiab kev txhawb nqa ntawm peb cov neeg siv khoom, thiab niaj hnub txhim kho peb cov khoom zoo thiab kev pabcuam qib kom muab peb cov neeg siv khoom zoo dua cov iav LED thiab cov kev pabcuam.
