Ua raws li cov kauj ruam yooj yim no los txhim kho lub hnub ci vaj huam sib luag thiab siv lub zog tsim los teeb rau koj lub vaj lossis kev tsav tsheb.
Fais fab koj LED downlight los ntawm lub hnub ci vaj huam sib luag yog ib tug zoo lub sij hawm ntev zog txuag kev daws teeb meem raws li nws yuav txo tau koj cov nqi zog. Los ntawm kev siv peb phau ntawv qhia, koj tuaj yeem txuag tau ntawm cov nqi teeb tsa thiab teeb tsa koj lub hnub ci vaj huam sib luag yam tsis muaj kev pab los ntawm tus kws tshaj lij.
Ua ntej, kuv yuav qhia koj yuav ua li cas txuas lub hnub ci vaj huam sib luag rau lub teeb LED. Koj tuaj yeem yooj yim nthuav cov kab ke kom tau txais txiaj ntsig ntxiv thaum koj paub tseeb.
Hauv kev teeb tsa yooj yim, txhua yam koj xav tau uas tsis yog lub hnub ci vaj huam sib luag thiab lub teeb ci LED yog ob lub xov hlau thiab lub resistor. Peb yuav txuas lub teeb LED ncaj qha rau lub hnub ci vaj huam sib luag. Tom qab ntawd kuv yuav qhia koj yuav ua li cas nthuav cov kab ke no los ntawm kev ntxiv ib qho kev hloov pauv, cov roj teeb rov qab, LED lossis tus tswj hwm, lub capacitor, transistor, thiab diodes. Kuv tseem yuav qhia koj seb yuav kuaj xyuas li cas yog tias koj xav tau.
Yam Koj Yuav Tsum Tau
Txhawm rau txuas lub hnub ci vaj huam sib luag rau lub teeb ci LED, koj yuav xav tau cuaj yam khoom nram qab no:
- Lub hnub ci vaj huam sib luag
- LED teeb
- LED tswj
- Nyob ntawm tej
- Cov Txuas Lus
- Hlau stripper
- Cov cuab yeej Crimping
- Ntsia thawv
- Soldering hlau
Ib qho LED feem ntau xav tau lub zog me me, yog li yog tias koj tsuas yog siv lub hnub ci vaj huam sib luag rau LED teeb pom kev zoo, nws tsis tas yuav loj lossis muaj zog. Thaum koj yuav ib lub hnub ci vaj huam sib luag koj yuav tsum muaj ib daim qauv ntawm cov kab hluav taws xob, tab sis yog tias koj tsis muaj ib qho nws yog cov txheej txheem yooj yim raws li tau piav qhia hauv qab no.

Txoj Kev Yooj Yim
Txoj kev yooj yim ntawm kev txuas lub hnub ci vaj huam sib luag rau LED teeb yuav tsum tau siv me me ntawm cov khoom siv thiab kev npaj.
Nws yog qhov tsim nyog rau cov xwm txheej no thaum koj xav kom ua tiav txoj haujlwm sai thiab tsis muaj zog. Nrog rau kev xaiv ntxiv, uas kuv yuav tham tom qab, koj tuaj yeem nthuav dav lub peev xwm ntawm qhov system tom qab.
Sib nrug los ntawm lub hnub ci vaj huam sib luag thiab LED, txhua yam koj xav tau yog tus tswj hwm LED (yeem), ob lub xov hlau thiab ib qho resistor.
Yog li ntawd, cia peb pib.
Yog tias koj saib tom qab ntawm lub hnub ci vaj huam sib luag, koj yuav pom ob lub terminals nrog lub polarity cim rau lawv. Ib qho yuav tsum tau cim qhov zoo lossis "+" thiab lwm qhov tsis zoo lossis "-". Txawm tias tsuas yog ib qho cim, koj yuav paub tias lwm tus muaj qhov sib txawv polarity.
Peb yuav txuas ob lub polarities zoo tib yam nrog cov xov hlau thiab ntxig ib qho resistor rau hauv cov hlau zoo. Ntawm no yog daim duab sib txuas:
Txhawm rau txuas lub hnub ci vaj huam sib luag rau LED teeb, nws yooj yim heev:
- Tshem tawm qhov kawg ntawm cov xov hlau (li ib nrab nti).
- Txuas cov xov hlau nrog lub cuab yeej crimping
- Txuas txhua tus pin mus rau lub connector rau txhua lub xaim raws li qhia hauv daim duab thaiv.
- Siv cov connectors no, txuas lub hnub ci vaj huam sib luag rau tus nqi tswj.
- Txuas mus rau lub charger regulator nrog ib tug ntswj ntsia hlau.
- Txuas lub LED maub los rau LED.
Tam sim no koj tuaj yeem siv lub hnub ci vaj huam sib luag los txhawb koj lub teeb pom kev zoo LED.
Kev sib txuas ib qho LED cais hauv Circuit Court raws li qhov taw qhia tuaj yeem ua rau pom qhov pom ntawm seb lub hnub ci vaj huam sib luag qhib lossis tawm (saib daim duab hauv qab).
Lwm yam Cheebtsam koj tuaj yeem suav nrog
Qhov chaw yooj yim saum toj no yuav raug txwv.
Txhawm rau tswj kev ua haujlwm ntawm LED kom zoo dua qub, koj tuaj yeem txuas lub LED mus rau LED maub los thiab tom qab ntawd mus rau lub hnub ci vaj huam sib luag. Tab sis muaj lwm yam khoom uas koj tuaj yeem txuas rau lub hnub ci vaj huam sib luag thiab LED Circuit Court koj ua.
Tshwj xeeb, koj tuaj yeem ntxiv cov hauv qab no:
- A hloov tswj lub Circuit Court, i.e. tig nws rau lossis tawm.
- Kev ntsuas roj teeb Yog tias koj xav siv lub teeb LED txuas nrog lub hnub ci vaj huam sib luag txhua lub sijhawm ntawm hnub uas tsis yog hnub ci.
- A tus nqi tswj tiv thaiv roj teeb los ntawm overcharging (yog tias koj siv lub roj teeb thiab muaj ntau tshaj 5 watts ntawm lub hnub ci zog rau txhua 100 Ah ntawm lub roj teeb muaj peev xwm).
- Kondensator Yog tias koj xav txo qis kev cuam tshuam thaum lub sijhawm ua haujlwm ntawm lub hnub ci vaj huam sib luag, piv txwv li thaum muaj ib yam dab tsi cuam tshuam los ntawm kev thaiv lub teeb ci. Qhov no yuav du tawm lub hwj chim mov ntawm lub vaj huam sib luag.
- PNP-transistor tuaj yeem siv los txiav txim siab txog qib dimming.
- A diode yuav xyuas kom meej tias tam sim no ntws hauv ib qho kev taw qhia, piv txwv li los ntawm lub hnub ci vaj huam sib luag mus rau LED teeb thiab roj teeb, thiab tsis ua rau lwm tus.
Yog tias koj txiav txim siab ntxiv cov roj teeb rov qab, kuv xav kom koj suav nrog lub diode hauv Circuit Court uas tsuas yog tso cai rau tam sim no ntws mus rau hauv ib qho kev taw qhia. Nyob rau hauv cov ntaub ntawv no, nws yuav cia nws ntws los ntawm lub hnub ci vaj huam sib luag mus rau lub roj teeb, tab sis tsis vice versa.
Yog tias koj siv lub capacitor, lub hauv paus LED teeb yuav xav tau 5.5 volt capacitor, lossis koj tuaj yeem siv ob lub capacitor ntawm 2.75 volts txhua.
Yog tias koj qhib lub transistor, nws yuav raug tswj los ntawm qhov voltage ntawm lub hnub ci vaj huam sib luag, yog li thaum lub hnub ci ci dhau lawm, lub transistor yuav tsum tua, thiab thaum tsis muaj hnub ci, qhov tam sim no yuav tsum ntws mus rau LED.
Ntawm no yog ib qho ntawm cov kev sib txuas ua ke, uas suav nrog lub roj teeb, lub transistor thiab ob lub diodes.
Kev kuaj tam sim no
Tej zaum koj yuav tau sim qhov tam sim no rau qhov ci lossis lwm qhov teeb meem ntawm lub zog nrog lub teeb LED.
Kuv mam li qhia koj seb nws ua li cas nrog lub zog qis LED hauv hluav taws xob circuits. Tshwj xeeb, kuv tau sim cov qauv no siv lub hnub ci vaj huam sib luag ntsuas ntawm 3 volts thiab 100 mA. Kuv kuj tau siv ib tug multimeter, ib tug gooseneck teeb thiab ib tug kav. Tsis tas li ntawd, koj yuav xav tau lub roj teeb rau qhov kev sim no.
Nov yog cov kauj ruam:
Kauj Ruam 1: Npaj koj lub multimeter
Teem lub multimeter los ntsuas DC tam sim no, hauv qhov no hauv 200 mA ntau yam.
Kauj Ruam 2 Txuas cov ntawv xeem
Txuas cov hlau lead liab ntawm lub hnub ci vaj huam sib luag mus rau cov hlau lead ntev ntawm LED siv ib qho alligator clip test lead. Tom qab ntawd txuas lub multimeter's liab xeem coj mus rau LED lub luv xaim, thiab nws cov kev sim dub ua rau lub hnub ci vaj huam sib luag dub hlau. Qhov no yuav tsum tsim ib tug series Circuit Court raws li qhia hauv qab no.
Kauj Ruam 3: Tshawb xyuas LED
Tso lub LED nyob rau hauv qhov ntsuas txog 12 ko taw (XNUMX ntiv tes) saum lub vaj huam sib luag thiab tig nws. LED yuav tsum teeb. Yog tias tsis yog, rov kuaj xyuas koj cov kab hluav taws xob multimeter thiab teeb tsa.
Kauj Ruam 4: Txheeb xyuas qhov tam sim no
Tau txais kev nyeem ntawv tam sim no ntawm multimeter. Qhov no yuav qhia koj raws nraim li cas tam sim no mus los ntawm LED. Koj tuaj yeem tshawb xyuas cov yam ntxwv ntawm LED kom paub tseeb tias muaj tam sim no txaus.
