1, LED tsav fais fab dab tsi yog dab tsi
LED tsav fais fab mov converts lub hwj huam mov mus rau ib qho voltage thiab tam sim no tsav tsheb LED lub teeb voltage converter. Raws li ib txwm muaj, cov tswv yim ntawm cov tsav fais fab tsav tsheb muaj xws li muaj siab zog fais fab AC (ie, mains), low-voltage DC, high-voltage direct current, thiab low-voltage high frequency. AC (xws li cov hluav taws xob hauv hluav taws xob) thiab lwm yam. Cov zis ntawm LED tsav yog feem ntau qhov tam sim no qhov chaw uas hloov qhov voltage li cov LED pem taub hau poob siab hloov. LED lub hwj chim tub ntxhais muaj xws li kev sib tsoo, kev sib txuas, kev hloov cov ntsiab lus (MOSfets), cov lus tawm resistors, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob tawm, thiab cov zoo li. Raws li kev sib txawv ntawm lub ntees, yuav tsum muaj cov tswv yim tshaj qhov ntsuas hluav taws xob, cov tswv yim nyob rau hauv-voltage tiv thaiv Circuit Court, LED qhib kev tiv thaiv Circuit Court, tiv thaiv kev tiv thaiv tshaj tam sim no.
2, LED tsav zog cov yam ntxwv
(1) Kev ntseeg siab
Hauv particular, tsav fais fab ntawm LED teeb teeb yog ntsia rau ntawm qhov chaw siab tshaj plaws, uas yog txav los tswj thiab cov nqi ntau rau kev txij nkawm.
(2) Kev ua haujlwm siab
LED yog ib qho khoom txuag hluav taws xob, thiab qhov ua tau zoo ntawm kev tsav tsheb tsav yog siab. Nws yog ib qho tseem ceeb heev rau lub cua kub dissipation ntawm lub hwj huam khoom nruab rau hauv lub teeb. Kev ua haujlwm ntawm lub hwj huam yog siab, nws lub hwj huam siv zog me me, thiab lub tshav kub generated hauv lub teeb yog me me, uas tseem txo qhov kub sawv ntawm lub teeb. Nws yog lig rau ncua lub lwj ntawm cov LED.
(3) High power tau
Qhov zoo tshaj yuav yog qhov kab sib chaws ntawm txoj cai. Cov khoom siv hluav taws xob hauv qab 70 watts feem ntau yuav tsis yuam. Txawm hais tias lub hwj huam hluav taws xob tsawg tsawg muaj lub hwj chim qis, nws muaj feem me me rau ntawm daim phiaj fais fab. Txawm li cas los xij, qhov loj ntawm teeb pom kev siv thaum hmo ntuj thiab cov kev thauj khoom zoo ib yam nkaus thiab muaj peev xwm ua rau muaj pa phem heev rau lub hwj chim. Rau 30-watt rau 40-watt LED tsav tsheb, nws tau hais tias yav tom ntej, tej zaum yuav muaj qee tus ntsuas ntawm kev tsim nyog yuav tsum tau muaj.
(4) Tsav tsheb
Muaj ob hom tsheb: ib qho yog ib qho hluav taws xob qhov hluav taws xob rau ntau qhov chaw tam sim no, thiab txhua qhov tam sim no qhov khoom siv fais fab rau txhua tus kheej LED. Li no, ua ke ntawm saj zawg zog, tag nrho txoj kev tsis ua hauj lwm uas tsis ua hauj lwm, tsis cuam tshuam rau kev ua hauj lwm ntawm lwm cov LEDs, tab sis tus nqi yuav yog me ntsis siab dua. Lwm qhov yog qhov ncaj qha tam zog tam sim no, uas yog kev tsav tsheb hloov los ntawm "Zhongke Huibao", thiab cov LEDs yog ua haujlwm hauv kab los yog hauv kev ua haujlwm. Nws qhov kom zoo dua yog tias tus nqi qis dua, tab sis qhov yooj yim yog pluag, tab sis kuj yuav kom daws tau ib yam tsis ua hauj lwm uas tsis ua hauj lwm, tsis cuam tshuam rau kev ua haujlwm ntawm lwm tus LED. Ob qho tib si coexist rau ib lub sij hawm ntawm lub sij hawm. Ntau cov qhov tso zis hluav taws xob cov khoom yuav zoo dua ntawd cov nqi thiab kev ua haujlwm. Tej zaum nws yuav yog qhov kev taw qhia dav dav rau yav tom ntej.
(5) Kev tiv thaiv kom zoo
Muaj peev xwm ntawm LED kom tiv thaiv surges yog kuj tsis zoo, tshwj xeeb tshaj yog tiv thaiv tsis tau rov muaj peev xwm. Nws tseem ceeb kom ntxiv dag zog rau txoj kev tiv thaiv no. Qee qhov teeb cig ntawm lub teeb muaj rau sab nraum zoov, xws li LED teeb. Vim lub caij pib ntawm qhov kab sib tsoo thiab qhov pib ntawm xob laim, ntau cov surges tuaj yeem raug cuam tshuam los ntawm kab sib chaws, thiab qee qhov surges tuaj yeem ua rau kev puas tsuaj rau LED. Yog li ntawd, kev tshawb xyuas ntawm "Suav Branch Hui Bao" tsav lub hwj chim ntawm kev tiv thaiv yuav tsum muaj qee qhov kev tsis txaus siab, thiab kev hloov ntawm cov khoom siv hluav taws xob thiab cov teeb txauv, LED tsav fais fab rau inhibit lub intrusion ntawm lub siab los tiv thaiv cov LED tsis puas.
(6) Kev tiv thaiv ua haujlwm
Ntxiv rau txoj kev tiv thaiv kev cai, nws zoo dua los ua kom qhov ntsuas kub kub tsis zoo hauv qhov tso tawm tam sim no kom tiv thaiv tau qhov ntsuas kub ntawm kev siab dhau; nws yog ib qho tsim nyog ua raws li cov cai ntawm kev nyab xeeb cov kev cai thiab kev sib tw electromagnetic.
