Nyob rau hauv lub siab ntawm qhov kawg nqi, lub lag luam yog yuam cov tuam txhab LED los hloov lawv lub tshuab, uas ntxiv txhawb nqa cov ntawv thov thiab qhov nrov ntawm cov tshiab technologies. Tus nqi ntawm LED khoom tseem poob qis dua, thiab kev tsim ua haujlwm tau los ua ib qho cuab yeej tsim kho kev lag luam, txo cov nqi, thiab nrhiav cov khoom muag. Nyob rau hauv lub siab ntawm qhov kawg nqi, lub lag luam yog yuam cov tuam txhab LED los hloov lawv lub tshuab, uas ntxiv txhawb nqa cov ntawv thov thiab qhov nrov ntawm cov tshiab technologies.
Technological innovation ib txwm yog ib qho tseem ceeb nyhav rau cov tuam txhab ua kom cov khoom muaj nqis. Nyob rau hauv ib tes, CSP ntim nplai ntim, ntxeev-CHIP LED, thiab cov tshuab hluav taws xob tawm tshuab tau maj mam loj hlob thiab pom tau hais ntau lawm. Lawv tau nthuav ntau yam los ntawm kev lag luam. Cov kauj ruam tom ntej yog ua kom nce nqi / kev ua tau zoo npaum li cas. Ntawm qhov tod tes, EMC, COB, thiab high-voltage LEDs Lub khw tseem tawg tawm thiab qhov chaw loj hlob yav tom ntej yuav tsom mus rau kev ua lag luam.
1, CSP nti nplai pob
Hais txog lub tshuab LED nrov tshaj plaws, tsis yog-CSP yuav tsum yog. CSP tau nyiam mloog vim nws qhov kev xav tau ntawm kev ua lag luam rau pob miniaturization thiab muaj txiaj ntsim zoo dua. Tam sim no, CSP yeej maj mam siv rau mobile flash, tso saib teeb pom kev zoo thiab lwm thaj chaw.
Nyob rau hauv luv luv, nyob rau theem no, CSP ntim nplai pob tseem nyob hauv kev tshawb nrhiav thiab kev loj hlob, thiab yuav ua raws li txoj kev txhim kho cov nqi-ua tau zoo. Nrog nruam tawm ntawm cov nyhuv ntawm CSP cov khoom, qhov kev ua tau zoo yuav ntxiv zog. Nyob rau lub xyoo tom ntej lossis ob, cov neeg yuav khoom txais ntau dua thiab ntau dua yuav tau txais CSP cov khoom.
2, rau lub hwj chim module
Nyob rau hauv xyoo tas los, "de-powered" tau tsim nyob rau hauv tag nrho viav vias. Dab tsi yog "de-powered" thaum kawg? "De-powered" txhais tau hais tias lub hwj huam ua hluav taws xob tau tsim kho, txo cov hluav taws xob cov hluav taws xob, cov twj thiab cov twj siv hluav taws xob, thiab cov tsav hluav taws xob thiab cov teeb teeb ci hauv lub teeb coj los sib koom ua ke, ua kom tiav cov tsav thiab cov teeb ci. Piv nrog rau cov tsoos LED, lub hwj huam khoom kua yog yooj yim thiab yooj yim dua rau cov khoom siv thiab ua kom muaj zog; tib lub sij hawm, nws tuaj yeem txo qhov me me thiab tus nqi.
3, ntxiab-chip LED tshuab
"Tig nplaum nti + nti nplai pob" yog ib qho ua ke zoo tshaj plaws. Tig-Chip LED nrog rau qhov zoo ntawm high ntom, siab tam sim no, ob lub xyoo dhau los ua ib lub ntsiab lus kub ntawm LED nti cov tuam txhab thiab cov kev taw qhia lub ntsiab ntawm txoj kev lag luam ntawm LED kev lag luam.
CSP pob tam sim no yog raws li tshuab kev siv hluav taws xob. Piv rau kev tsim coj, ntxeev-chip LED eliminates qhov yuav tsum tau ntaus tus kub txuas, uas txo qhov yuav qhov teeb meem ntawm lub tuag teeb los ntawm ntau tshaj 905, uas ua kom ruaj ntseg ntawm qhov khoom thiab optimizes lub zog dissipation muaj peev xwm ntawm cov khoom. Nyob rau tib lub sijhawm, nws tuaj yeem zam ntxiv tsav tsheb, luminous flux thiab thinning cov yam ntxwv nyob hauv ib cheeb tsam me me, thiab yog qhov zoo tshaj plaws rau kev tsav tsheb dhau ntawm kev tsav tsheb thiab kev pom kev nrig.
4, EMC pob
EMC hais txog epoxy molding compound, uas yog thaum kub kub ua haujlwm, UV ua haujlwm, siab ua ke, siab khiav tam sim no, me me, kev ruaj siab, thiab lwm yam.
Nws to taub tias EMC tam sim no muaj 3030, 5050, 7070 thiab lwm yam qauv, uas cov nqi ntawm 3030 tau zoo heev.
5, high voltage LED pob
Tam sim no tus nqi hluav taws xob cov nqi hluav taws xob yog tsiv thiab tsiv, thiab lub hwj huam yog qhov tseem ceeb ntawm tag nrho cov LED. Yuav ua li cas kom txuag tau tsav nqi tau ua lub hom phiaj ntawm LED drive fais fab tuam txhab. High-voltage LEDs tuaj yeem txo cov nqi ntawm cov khoom siv fais fab thiab tau raug txheeb xyuas tias yog ib txoj kev lag luam loj hlob yav tom ntej.
Tam sim no, qhov kev xyaum ntawm kev ua kom pom muaj zog LED yog ua kom muaj zog loj dua los sis ua kom qhov kev khiav hauj lwm tam sim no, tab sis nws tsis yooj yim rau kev daws teeb meem, thiab tej zaum yuav ua rau muaj teeb meem tshiab, xws li tsis sib luag tam sim no, tsis muaj hluav taws xob dissipation, thiab Droop nyhuv, tab sis lub siab-voltage nti Muab kev daws zoo dua.
Lub hauv paus ntawm high-voltage nti yog tiag tiag los siv lub tswv yim ntawm integerization kom decompose loj chips rau me me chips nrog high luminous efficiency thiab lub teeb lub teeb emission, thiab mus ua ke lub semiconductor txheej txheem technology kom tag nrho siv ntawm chip cheeb tsam. , zoo tshaj qhov ua tiav lub hom phiaj ntawm qhov ci ntsa iab. Ntawm qhov kev pom ntawm tag nrho cov teeb (xws li txoj kev teeb), lub siab-voltage nti nrog IC lub hwj huam, qhov fais fab mov voltage qhov txawv me me, ntxiv rau qhov kev pab cuam lub neej, tab sis kuj yuav txo tau tus nqi ntawm lub system .
6, COB integrated pob
COB kev teeb pom kev zoo yog qhov yooj yim kom ncav tsis cuag, ua rau tsis zoo, ci ntsa iab thiab lwm yam ntxwv, tuaj yeem daws qhov teeb meem ntawm cov kob thiab cua sov, thiab yog dav siv coj mus muag teeb pom kev zoo thiab tau los ntawm ntau lub hnab ntim khoom lag luam.
Nyob rau theem no, COB tabtom ntsib txoj haujlwm ntawm kev ua haujlwm. Nyob rau hauv lub neej yav tom ntej, lub COB ua lag luam yuav tsim tawm los ntawm cov qauv khoom. Raws li cov kev lag luam hauv qhov COB ntws los ntawm cov COB kuj yog cov qub txeeg qub teg thiab raug nqi, thaum cov kev sib txig sib luag daws tau, qhov kev ntsuas yuav ntxiv zuj zus ntxiv.
