Qhov shortcomings ntawm LED vaj huam sib luag lub teeb muaj nyob rau hauv cov teeb meem ntawm kev tsis ncaj ncees ntawm cov teeb meem hluav taws xob thiab lub neej luv luv ntawm cov ntaub ntawv ntim. Txawm hais tias qhov kev cia siab zoo ntawm lub teeb dawb LEDs yuav siv tsis tau, tab sis los ntawm qhov pom ntawm qhov kev thov, qhov no tsis yog siv dav xwb, tab sis nrog kev siv dav ntawm cov xov tooj ntawm tes, tv, tsheb thiab lwm yam kev lag luam, ua qhov tsim nyog tshaj plaws ntawm dawb LED technology tshawb fawb tau txais kev txhawj xeeb thoob plaws.
Tam sim no muaj ob qho kev qhia tseem ceeb rau kev txhim kho lub teeb pom kev zoo ntawm cov LEDs dawb. Ib qho yog ua kom thaj tsam thaj tsam ntawm LED chip kom nce ntau ntawm cov teeb pom kev. Qhov thib ob yog los ntim ob peb lub pob me me sib xyaw ua ke nyob rau hauv tib qho qauv los ntawm kev nce qib hauv cheeb tsam kom nce qhov nyiaj ntau ntawm lub teeb. Txawm hais tias thaj tsam ntawm cov LED nti kom loj dua, nws tuaj yeem muab ntau qhov ci ci ntau dua, tab sis vim tias thaj chaw loj, Yuav muaj cov khoom cuav tshwm sim hauv cov ntawv thov cov txheej txheem thiab cov txiaj ntsig tau. Yog li ntawd, txhawm rau txhawm rau daws cov teeb meem no, qee qhov chaw tsim hluav taws xob LED tau txhim kho qhov chaw ntawm cov nti ua raws cov kev txhim kho ntawm cov qauv hluav taws xob thiab cov qauv teeb tsa cov nplaim hluav taws xob kom ua tiav qhov teeb meem ntawm 50lm / W.
Piv txwv li, nyob rau hauv pob flip-chip pob ntawm cov teeb ci vaj huam sib luag LED, txij li lub teeb txheej hluav taws xob ze rau cov txheej txheem qhia teeb, cov electrode yuav tsis muaj kev thaiv thaum lub teeb ntawm lub teeb ci ntsa tawm mus rau sab nraud. , tab sis qhov tsis zoo yog qhov tsim kom muaj cua sov tsis yooj yim.
Nws tsis yog tom qab txhim kho lub nti saum npoo, ntxiv rau qhov chaw nti ntau dua, tias qhov ci ntsa iab tuaj yeem tuaj yeem nce sai, vim tias thaum lub teeb txawv ntawm sab hauv ntawm lub nti, cov ntu zoo hauv nti tsis tuaj yeem xav txog, yog li yuav muaj me ntsis ntawm lub teeb tshem. Kev Txwv. Raws li kev suav, LED nti loj uas zoo tshaj plaws cov teeb pom kev zoo yog txog 7mm2.
Yog lawm, txoj hauv kev no tseem yuav ua qee qhov teeb meem uas zam tsis dhau. Piv txwv li, vim tias ntau LEDs tau ntim rau ntawm tib qho qauv, qee cov ntaub ntawv insulating yuav tsum muab tso rau hauv kom tsis txhob luv luv ntawm cov chips LED. Nws yuav nce nqi ntau. Tab sis los ntawm qhov pom ntawm kev tiv thaiv ib puag ncig, qhov no muaj ntau qhov zoo dua qhov tsis zoo.
