LED yog ib qho cuab yeej hluavtaws nruab nrab, tiam sis tseem muaj qhov kub tsis zoo, thiab yog li cov txheej txheem ntawm daim ntawv thov kom nws ruaj khov rau kev ua haujlwm thiab kev tiv thaiv, ua rau lub tswvyim tsav. LED li ntawm tsav lub zog yuav tsum nyob ze ntawm lub hnyav, LED tsis zoo li cov nquag siv qis dua, koj tuaj yeem ncaj qha mus cuag 220V AC mains. LED yog hais txog 3 volts tsawg voltage tsav, koj yuav tsum tsim ib txoj kev hloov ua vajtse, siv ntau ntawm cov teeb ci, kom muaj peev xwm sib xyaw nrog lub zog txawv adapter. Lub lag luam thoob ntiaj teb rau cov neeg tuaj txawv teb chaws tuaj rau ntawm cov tsav tsheb hluav taws xob ntawm cov tsav hluav taws xob, kev siv hluav taws xob, kev siv hluav taws xob, kev siv hluav taws xob lub neej, kev tsim kom muaj qhov sib txawv ntawm cov khoom siv hluav taws xob, kev tsim ntawm lub hwj huam zoo yuav tsum coj mus rau hauv cov txiaj ntsig zoo, vim tias lub hwj chim tag nrho lub teeb Lub luag haujlwm yog zoo li lub plawv ntawm tib neeg.
Vim lub zog ntawm LED zog xyuas, feem ntau yuav tsum tau tsav ntau lub LEDs tib lub sij hawm kom tau raws li cov kev cai uas tsim nyog, yog li ntawd, xav tau ib lub voj voog tsav tshwj xeeb los teeb lub LED. Ntawm no yog lub ntsiab mainstream ntawm ob peb tsav tsheb:
1, RC peev nqis-nqis
Kev siv cov peev txheej hauv AC impedance los txo cov tswv yim tam sim no, thiaj li mus muab DC theem rau lub hwjchim ntawm cov hluav taws xob. Txoj kev tsav tsheb no yooj yim, qis tus nqi, tab sis qhov kev pab cuam uas tsis yog cais tawm, muaj kev ruaj ntseg muaj kev ruaj ntseg. Thiab qhov kev hloov dua siab tshiab yog qhov tsawg tsawg, tsis tuaj yeem tswj qhov kev tswj tam sim no.
2, Kuv solated flyback Circuit Court
Kev siv hluav taws xob khiav tawm, los ntawm kev siv lub tshuab hluav taws xob hauv theem nrab ntawm DC, thiab tom qab ntawd los ntawm optocoupler no qib ntawm lub ripple rov qab mus rau sab xub thawj, thiab yog li nws tus kheej-stabilization. Xws li cov khoom siv ua tau raws li kev ruaj ntseg raws li, thiab cov zis qhov tam sim no yog qhov zoo dua, kev hloov dua siab tshiab dua. Tab sis vim txoj kev xav tau rau optocoupler thiab theem ob qho tam sim no tswj kev sib cog lus, ua rau txoj system, loj loj, siab raug nqi. Tau maj mam hloov los ntawm thawj qhov kev pab cuam.
3, T nws thawj sab ntawm txoj haujlwm
Sab xub thawj ntawm qhov kev zov me nyuam tag nrho los ntawm kev tswj ntawm qhov tso zis sab ntawm lub zog thiab tam sim no cov zis, qhov tseeb tshaj plaws ua tau 5% qhov tseem niaj hnub tam sim no, lub secondary tsuas yog ib qho hluav taws xob qhov hluav taws xob tawm tau. Lub hauv paus sab nraud tsuas yog los ntawm cov tswv yim ntawm sab nraud thiaj li tswj tau cov twj tso tawm qhov hluav taws xob, relying rau qhov tam sim no kev tswj resistor los tswj cov thawj tam sim no, thiab muab tus lem ratio los tswj cov zis tam sim no. Cov kev pabcuam yuavtsum yog qhov tseemceeb ntawm qhov kev sibtw hauv yias, qhov tseemceeb yog qhov tsimnyog, muaj peevxwm tsawg tsawg thiab tsis raug nqi, dhau los ua tus neeg tsav tsheb.
Sab xub thawj ntawm qhov teeb meem tam sim no qhov teeb meem: qhov tseeb ntawm lub siab tsis yooj yim los tswj, ua rau sab xub thawj ntawm qhov kev pab cuam siv cov kev hloov tsis tshua muaj kev hloov, cov zis tam sim no loj dua. Yog li, tus thawj sab ntawm qhov kev zov me nyuam los ntawm kev txhim kho ob sab ntawm qhov kev tswj xyuas tam sim no, kom tias txawm yog thawj sab ntawm qhov kev pab cuam tshaj li qhov nyuaj, tab sis piv rau qhov kev pab cuam cuam tshuam, koj tuaj yeem txuag tau qhov optocoupler, raug nqi.
Raws li cov cai ntawm daim phiaj fais fab thiab LED tsav fais fab ntawm cov tseev kom muaj, xaiv thiab tsim LED tsav fais fab mus rau hauv tus account cov nram qab no cov ntsiab lus:
1, H zoo siab
Tshwj xeeb tshaj li LED teeb tsav fais fab, ntsia nruab nrab qhov siab tshaj plaws, txij nkawm tsis yooj yim, txij nkawm nqi kuj tseem loj.
2, H zoo siab
LED yog cov khoom txuag hluav taws xob, tsav hluav taws xob ua haujlwm zoo dua. Nws yog qhov tshwj xeeb tshaj yog rau lub hwj huam khoom muab ntsia rau hauv lub qhov rooj. Vim LED luminous efficiency nrog LED kub nce thiab poob, ces tus kub kub tseem ceeb heev. Fais fab tuag yog qhov siab, nws lub hwj huam siv zog me me, nyob rau hauv lub teeb kub yog me me, nws yuav txo qhov teeb kub. Hloov cov teeb ci LED tsis ua haujlwm zoo.
3, H huag zog tau
Qhov zoo tshaj yuav yog qhov khoom ntawm lub kab sib chaws. Feem ntau qis dua 70 watts ntawm cov khoom siv hluav taws xob, tsis muaj cov cim tseem ceeb. Txawm hais tias lub hwj chim tsis yog tib lub hwj chim tau qis zog ntawm lub hwj chim ntawm qhov me me, tiam sis thaum hmo ntuj peb pom, zoo li lub nra yuav dhau mus, yuav tsim muaj cov pa phem ntau ntawm kab sib chaws. Rau 30 watts mus 40 watts ntawm LED tsav fais fab, nws yog hais tias nyob rau hauv rau yav pem suab, tej zaum yuav muaj ib cov degree ntawm qhov yuav tsum tau muaj zog.
4, D txhawm rau txoj kev
Tam sim no muaj ob hom kev khiav tsheb: ib qho yog ib qho chaw qhov chaw nyob rau ib qhov chaw tam sim no qhov chaw, txhua qhov tam sim no qhov twg los tau rau txhua lub hwj huam hluav taws xob. Li no, ua ke ntawm saj zawg zog, tag nrho txoj kev LED tsis ua, tsis cuam tshuam rau kev ua haujlwm ntawm lwm tus LED, tab sis tus nqi yuav yog me ntsis siab dua. Qhov thib ob yog qhov ncaj qha tam sim no lub hwj huam mov, LED series los yog cov txheej txheem ua haujlwm. Nws qhov kom zoo dua yog qhov tsawg dua tus nqi, tab sis qhov yooj yim yog pluag, tab sis kuj yuav kom daws tau qhov tsis ua hauj lwm uas tsis ua hauj lwm, tsis cuam tshuam rau lwm yam lag luam hauv lub lag luam. Cov ob hom coexist rau ib lub sijhawm. Ntau cov channel tso zis hluav taws xob tam sim no, saib nqi thiab kev ua haujlwm yuav zoo dua. Tej zaum yav tom ntej ntawm lub hauv paus.
5, Txhawb kev tiv thaiv
LED tsis pub muaj peev xwm muaj peev xwm kuj yog cov neeg txom nyem, tshwj xeeb tshaj yog muaj peev xwm ua kom tsis muaj zog. Nws tseem ceeb kom ntxiv dag zog rau txoj kev tiv thaiv no. Muaj qee qhov teeb ci teeb nyob rau sab nraum zoov, xws li LED teeb. Vim yog lub nra ntawm cov kab sib tsoo thiab hluav taws xob induction, los ntawm kab sib chaws system yuav cuam tshuam ntau yam surges, thiab ib co surge yuav ua rau cov kev puas tsuaj rau LED. Li ntawd LED tsav fais fab rau suppress lub surge ntawm intrusion, kev tiv thaiv ntawm LED yog tsis puas muaj peev xwm.
6, P kev sib hloov
Fais fab mov Ntxiv nrog rau qhov kev tiv thaiv kev tiv thaiv kab mob, nws yog qhov zoo tshaj kom ua qhov teeb meem tam sim no qhov ntsuas kub kub tsis zoo siab tawm tswv yim kom tiv thaiv tau qhov kub kub.
7, P kev sib nrauj
Teeb nrawm sab nraum lub hom installation, lub hwj chim ua rau tsis muaj dej, tsis muaj dej, lub plhaub rau lub teeb.
8, T nws lub neej ntawm tsav lub zog kom zoo li lub neej ntawm LED.
9, T o ua kom tau raws li kev xav tau ntawm kev nyab xeeb thiab kev sib tw electromagnetic.
Nrog cov qoob loo loj hlob ntawm LED, LED tsav fais fab kev ua haujlwm yuav ntau dua thiab tsim dua rau cov cai ntawm LED.
Cov khoom kub: LED thaum muaj xwm ceev , teeb txawb teeb pom kev zoo , LED tshem tawm txoj kab teeb txawb , 2'x4 'LED vaj huam sib luag
