Lub Plaub Hlis thiab Tsib Hlis yuav tsum yog lub caij muag khoom siab tshaj plaws rau lub tuam txhab kub cuaj nyiaj kaum, tab sis tag nrho cov kev ua tau zoo ntawm LED kev lag luam tsis txaus siab. Ntxiv rau qhov cuam tshuam los ntawm cov nthwv dej yav dhau los ntawm kev nce nqi ntawm cov khoom siv raw xws li semiconductor chips, PCBs, thiab cov hlaws teeb los ntawm LED cov tuam txhab hluav taws xob, nws kuj tau cuam tshuam los ntawm nthwv dej tshiab ntawm "crit" - lub zog tswj ob lub zog. xaj.
sai li sai tau raws li txoj cai tswj hwm kev txwv ob lub zog tau tshaj tawm, sab nraum zoov LED zaub loj cov ntxaij vab tshaus yog thawj zaug uas cuam tshuam tsis zoo, feem ntau vim tias sab nraum zoov LED pob tshab cov ntxaij vab tshaus siv lub zog ntau. Thaum lub zog raug txiav, ntau sab nraum zoov loj cov ntxaij vab tshaus yuav tsum tau "tsis ua haujlwm". Nyob rau tib lub sijhawm, LED tuam txhab lag luam yuav inevitably txiav txim siab los txo qhov ntau lawm, uas cuam tshuam ncaj qha rau lub tuam txhab xa khoom ntawm LED khoom.
Feem ntau, LED pob tshab npo kev lag luam muaj qhov cuam tshuam me me rau kev txwv hluav taws xob, tab sis peb yuav tsum tsis txhob kwv yees nws. Kev lag luam LED kev lag luam yog nyob ntawm qhov khoom siv hluav taws xob tas li. Ntau cov kab ntau lawm yuav raug nqi kom nres thiab pib, thiab kev siv hluav taws xob yuav txo qis kev khiav hauj lwm. Yog tias kev tsim hluav taws xob mus ntev tau txwv, tsis yog kev xa khoom qeeb xwb yuav raug cuam tshuam, tab sis kuj yog cov nqi khoom yuav nce ntxiv. Piv txwv li, kev txwv fais fab tau cuam tshuam rau cov khoom siv raw ntawm cov khoom siv hluav taws xob nyob rau sab saud ntawm LED zaub kev lag luam, suav nrog tooj liab, zinc, txhuas, thiab lwm yam, uas yog cov khoom tseem ceeb raw khoom rau wafer thiab chip manufacturing nyob rau hauv upstream ntawm kev lag luam, thiab. cov nqi ntawm cov khoom siv raw tau nce ntxiv.
Nws yog qhov tsis lees paub tias qhov nce ntawm LED cov khoom siv raw thiab tsis txaus tsav nti tsim muaj peev xwm ua rau muaj kev cuam tshuam loj rau LED zaub kev lag luam. Kev txiav hluav taws xob tam sim ntawd thiab kev tsim khoom raug kaw hauv ntau qhov chaw txij li lub Plaub Hlis tau ua rau cov tuam txhab LED zaub uas nyuam qhuav tshwm sim los ntawm qhov cuam tshuam ntawm kev sib kis loj zuj zus. . LED pob tshab npo kev lag luam daws qhov teeb meem li cas? LED tuam txhab uas muag yuav tsum tau ua raws li nram no: 1. Tsim nyog npaj ntau lawm, rov kho lub tuam txhab txoj kev npaj ntau lawm rau ncov-hloov fais fab noj. 2. Zam kev txiav txim tsis raug, thiab faib lub peev xwm rau cov cheeb tsam uas muaj kev txwv tsis pub siv hluav taws xob 3. Cov khoom siv hloov kho thiab hloov pauv, cov cathode voltage ntau kom txo tau lub zog siv ntawm cov txheej txheem ntau lawm thiab txo qhov kub ntawm qhov screen.
