• Qhwv ib qho kawg ntawm cov xaim nyob ib ncig ntawm thawj qhov kev siv me ntsis ua lub voj thiab tom qab ntawd muab cov xaim nyob ib puag ncig txhua qhov kev siv me ntsis tom ntej ua txoj hlua ncaj nrog 8 loops raws nws qhov ntev.

Qhov no yuav siv qee qhov kev xyaum tab sis sim thiab tswj cov hlau tom qab tsim txhua lub loops kom tau xaim ncaj li sai tau. Maj mam muab cov hlau los ntawm cov khoom siv laum thiab tom qab ntawd sim ua kom ncaj ncaj.

Rau lub voos xwmfab zaum kawg koj yuav xav tau 16 qhov ntev ntawm xaim txhua nrog 8 lub loops tab sis thaum lub sijhawm tsim cov txheej txheem nws yooj yim kom muaj tus lej ntawm ob thiab peb lub voj qhov ntev mus rau tes txhawm rau txhawb nqa txhua daim tshiab nrog nws cov neeg nyob ze.

Thaum kawg peb tuaj yeem tsim lub voos xwmfab

Peb yuav tsum tau tsa PCB tawm ntawm qhov chaw txhawm rau ua kom sib luag thiab txo qis txhua daim mus rau PCB. Kuv siv ob peb lub thawv yas me me ntawm ob sab ntawm PCB.

Nco ntsoov koj txoj kev taw qhia ntawm daim hlais uas tau xaiv ua ntej thaum txheeb xyuas qhov chaw ntawm qhov txwv tam sim no koj tuaj yeem tam sim no txo thawj hlais rau hauv lub qhov hauv PCB ntawm ib kawg. Kuv hais qhia koj pib nrog qhov deb ntawm qhov deb ntawm koj thiab ua haujlwm rau koj tus kheej.

Nov yog qhov uas peb pom qhov zoo ntawm kev txiav cov kab hluav taws xob cathode ntawm lub kaum ntse ntse. Qhov no yuav tso cai rau koj nrhiav txhua ntawm 24 tus xov tooj cua cathode ib tus zuj zus.

Txhawm rau txhawb cov hlais thiab txheeb xyuas nws qhov chaw ntsug Kuv tau siv txoj kab ntoo uas peb tau siv los ua cov txuas hluav taws xob thiab muab qhov no tso rau ntawm PCB nyob hauv thawj txheej ntawm LEDs. Nrog cov kws tsim vaj tsev siv los xyuas kom cov hlais yog qhov sib dhos rau PCB thiab qib ntawm qhov kawg mus rau qhov kawg tam sim no koj tuaj yeem muab cov kab hluav taws xob txuas rau hauv PCB.

Koj tuaj yeem sim cov hlais tam sim no tab sis kuv pom nws zoo tshaj tso thawj ob daim hlais mus rau PCB thiab siv luv 2 lub voj anode txuas ntawm ob peb qhov chaw nyob ntawm ob daim ua ntej kuaj ua ntej ua thawj ob daim ntawv no ruaj khov. Tom qab thawj ob qhov kev sim no txhua qhov hlais ua ntej ntxiv rau tom ntej.

Kuaj cov hlais

Cov neeg tsav tsheb anode nyob ntawm ib sab ntawm PCB thiab muaj qhov nyob hauv PCB uas peb thaum kawg yuav txuas txhua txheej rau nws tus tsav tsheb. Txog tam sim no peb yuav siv cov no nrog qee lub cav xaim thiab 8 daim kab xaum me me kom txuas rau txhua txheej hauv txhua daim hlais.

Nrog cov cathodes soldered nqes mus rau PCB thiab anodes txuas nrog cov tsav tsheb nrog cov xov hlau thiab cov clip peb tuaj yeem sim cov hlais los ntawm kev hloov kho cov cai peb siv los ntsuas PCB nrog cov duab tshiab.

• Sau cov tsiaj ntawv yooj yim kom pom txhua lub LED hauv koj daim hlais txhua xim nyob rau ib lub sijhawm (tag nrho Liab, tom qab ntawd ntsuab ces Liab tag nrho rau Dawb). Koj tuaj yeem txhais tus lej tus lej ua qhov sib txawv yog li koj tuaj yeem hloov kho qhov no thaum koj sim txhua daim hlais.
• Txuas tus txheej txheem thiab lub zog rau PCB thiab tig rau.
• Txheeb xyuas txhua lub LEDs kom pom txhua xim.

Tsuas yog qhov tsis xws uas kuv tau pom ntawm no yog vim qhov sib koom ua ke qhuav ntawm ib qho ntawm txoj kab ntsug cathode kab hlau.

Kuaj thiab ntsuas txhua daim nyob rau hauv lem.

Yuav luag nyob ntawd. Muaj ob lub ntsiab lus ntxiv uas peb xav tau ntxiv rau lub voos xwmfab tam sim no peb tau muab tshuaj txhuam thiab kuaj tag nrho 8 ntawm daim ntawv.

Anode txheej txuas

Tam sim no peb tuaj yeem tshem tawm qhov txuas txuas anode nrog 8 loops koj tau npaj ua ntej.

Xov cov no hla cov hlais koom nrog tib txheej hauv txhua daim ntawm ob qho swb. Kuv txav kuv mus txog thaum lawv nyob deb li 5mm ntawm qhov ze tshaj plaws LED cathode hlau. Xyuas kom lawv saib ncaj thiab qib ua ntej yuav siv tag nrho cov loops thiab koom nrog txhua ntawm 8 anode txheej ua ke.

Anode tsav txuas

Tshem tag nrho cov xov hlau yav dhau los siv los ntsuas cov hlais los ntawm qhov anode tsav lub qhov nyob hauv PCB thiab xyuas kom tseeb tias lub qhov pom tseeb ntawm cov kab laug sab - cov kab laug cam yog koj tus phooj ywg nyob ntawm no.

Txhua ntawm 8 tus neeg tsav tsheb anode ntawm PCB yuav tsum tau txuas nrog rau ib tus neeg txheej ntawm PCB. Tus neeg tsav tsheb anode nyob ze tshaj ntawm kev sib txuas hluav taws xob ntawm PCB yuav tsum txuas nrog qib qis tshaj, tom qab ntawd ua haujlwm rov qab zuj zus mus rau tom qab ntawm PCB thiab txheej txheej thib 8.

Khoov lub kaum sab xis me me hauv ib qho ntawm cov kab sib txuas ncaj qha thiab txo qis sab ntev ntawm cov hlau hla lub voos xwmfab mus rau hauv qhov anode tsav lub qhov ntawm PCB. Ua kom ntseeg tau tias cov hlau ncaj thiab qib, tsis txhob kov lwm cov hlau hauv lub voos xwmfab thiab tom qab ntawd muab qhov no tso rau hauv txheej txheej txheej ntawm lub voos xwmfab thiab mus rau PCB

Ua tiav rau tag nrho 8 tus neeg tsav tsheb anode.
