Kev ntsuas LED teeb yog qhov yooj yim nrog lub digital multimeter, uas yuav ua rau koj pom meej txog qhov muaj zog ntawm txhua lub teeb. Qhov ci ntawm LED thaum koj sim nws tseem yuav qhia nws qhov zoo. Yog tias koj tsis muaj lub ntsuas ntsuas los siv, ib qho yooj yim npib ntawm cov roj teeb nrog cov coj yuav qhia rau koj paub yog tias koj lub teeb LED tseem ua haujlwm.
Cov kauj ruam
Txoj Kev 1 ntawm 2: Siv Multimeter
Kauj Ruam 1. Yuav ib lub digital multimeter uas tuaj yeem nyeem cov diode
Cov ntsuas hluav taws xob yooj yim ntsuas tsuas yog amps, volts, thiab ohms. Txhawm rau ntsuas LED teeb koj yuav xav tau lub multimeter nrog teeb tsa diode. Txheeb xyuas online lossis ntawm koj lub khw muag khoom kho vajtse hauv ib cheeb tsam rau nruab nrab mus rau qib siab ntau ntau, uas muaj feem yuav muaj cov yam ntxwv no ntau dua li cov qauv pheej yig.
- Qhov ntsuas qhov ntsuas nruab nrab nruab nrab zoo yuav yuav raug nqi ntawm $ 50-100 USD.
- Xaiv rau digital multimeter hla tus qauv analog, uas yuav nyuaj rau nyeem thiab tsis ntseeg tau.
Kauj Ruam 2. Nqa cov xim liab thiab dub coj mus kuaj
Kev ntsuas liab thiab dub yuav tsum txuas nrog lub qhov hluav taws xob nyob rau sab xub ntiag ntawm lub ntsuas cua. Cov hlau lead liab yog tus nqi zoo. Cov hlau lead dub yog qhov tsis zoo thiab yuav tsum tau muab ntsaws rau hauv cov ntawv sau hais tias "COM."
Kauj Ruam 3. Tig lub multimeter hu mus rau qhov teeb tsa diode
Tig lub xov tooj ntawm sab xub ntiag ntawm koj lub multimeter raws lub moos kom txav nws deb ntawm txoj haujlwm "tawm". Khaws nws kom txog thaum koj tsaws ntawm qhov teeb tsa diode. Yog tias nws tsis tau hais meej meej, qhov teeb tsa diode tuaj yeem sawv cev los ntawm lub cim diode Circuit.
Lub cim diode pom kev nruab nrab ob qho tib si nws cov davhlau ya nyob twg, cathode thiab anode
Kauj Ruam 4. Txuas qhov kev sojntsuam dub mus rau cathode thiab cov tshuaj sojntsuam liab mus rau qhov anode
Kov qhov kev sojntsuam dub mus rau qhov kawg cathode ntawm LED, uas feem ntau yog luv luv. Tom ntej no, kov lub liab sojntsuam mus rau lub anode, uas yuav tsum tau ntev prong. Nco ntsoov txuas cov ntawv soj ntsuam dub ua ntej qhov kev sojntsuam liab, vim tias qhov thim rov qab yuav tsis muab rau koj nyeem tau raug.
- Nco ntsoov tias cathode thiab anode tsis kov ib leeg thaum lub sijhawm ntsuas no, uas tuaj yeem tiv thaiv qhov tam sim no dhau los ntawm lub teeb ci LED thiab cuam tshuam koj cov txiaj ntsig.
- Cov kws tshuaj ntsuam dub thiab liab yuav tsum tsis txhob kov ib leeg thaum kuaj.
- Ua qhov kev sib txuas yuav tsum ua rau LED ci.
Kauj Ruam 5. Txheeb xyuas tus nqi ntawm lub multimeter's digital display
Thaum cov neeg soj ntsuam tau kov cov cathode thiab anode, lub teeb uas tsis raug teeb tsa yuav tsum tso tawm qhov hluav taws xob kwv yees li 1600 mV. Yog tias tsis muaj kev nyeem tshwm ntawm koj lub vijtsam thaum sim, pib dua kom paub tseeb tias kev sib txuas tau ua tiav. Yog tias koj tau ua qhov kev ntsuas kom raug, qhov no yuav yog lub cim qhia tias lub teeb LED tsis ua haujlwm.
Kauj Ruam 6. Txheeb xyuas qhov ci ci ntawm LED
Thaum koj ua qhov kev sib txuas tsim nyog los ntsuas koj lub LED, nws yuav tsum ci. Tom qab sau ntawv nyeem ntawm lub vijtsam digital, saib ntawm LED nws tus kheej. Yog tias nws tau nyeem ib txwm tab sis zoo li tsis pom, nws yuav yog qhov tsis zoo ntawm LED. Yog tias nws ci ntsa iab, tej zaum nws yog qhov ua haujlwm siab LED teeb.
Txoj Kev 2 ntawm 2: Xeem nrog Npib Cell Roj Teeb
Kauj Ruam 1. Siv lub npib cell roj teeb los ntsuas koj lub LED yam tsis hlawv nws
Cov roj teeb ntawm lub npib yog qhov kev nyab xeeb tshaj plaws vim tias lawv tsis tso tawm tam sim no txaus kom ua rau puas tsuaj. Kev sim nrog lwm hom roj teeb tuaj yeem hlawv koj lub teeb LED. Yuav cov roj teeb no ntawm cov chaw muag tshuaj, khw muag khoom, khw muag khoom kho vajtse, lossis online.
Siv CR2032 lossis CR2025 npib cell roj teeb
Kauj Ruam 2. Yuav ib lub npib xov tooj ntawm tes uas muaj roj teeb nrog cov coj
Yuav ib qho uas tau ua los tuav hom roj teeb ntawm tes (piv txwv li, CR2025) koj yuav raug sim nrog. Koj tuaj yeem pom cov no hauv online lossis ntawm qee lub khw muag khoom kho vajtse lossis khoom siv hluav taws xob. Nco ntsoov tias tus tuav muaj liab thiab dub coj mus kuaj teeb LED.
Cov neeg tuav lub roj teeb npib feem ntau yog siv los ntxiv roj teeb rau cov haujlwm me me xws li cov hniav nyiaj hniav kub lossis cov khaub ncaws
Kauj Ruam 3. Txuas cov hlau lead dub rau cov cathode thiab cov hlau liab coj mus rau anode
Txhawm rau ntsuas koj lub LED, kov lub taub hau ntawm qhov kev sojntsuam dub mus rau cathode, lossis luv kawg ntawm LED. Kov qhov taub ntawm qhov kev sojntsuam liab mus rau anode, uas yuav tsum yog qhov ntev dua. Nco ntsoov tias ob qhov kev sojntsuam tsis kov ib leeg thaum lub sijhawm ntsuas no, thiab cov cathode thiab anode tsis kov ib leeg.
- Qee tus neeg tuav lub roj teeb nrog cov coj yuav tuaj nrog lub txuas me me ntawm qhov kawg, tuav cov lus qhia ntawm ob tus coj.
- Yog tias koj lub roj teeb muaj lub txuas txuas, ntsuas koj lub LED los ntawm kev tso cov anode thiab cathode rau hauv qhov qhib me me uas ua kab nrog cov kab liab thiab dub.
Kauj Ruam 4. Tos kom LED ci
Yog tias LED ua haujlwm tau zoo thiab cov hlau lead sib txuas tau ua kom raug, koj lub LED yuav tsum teeb thaum koj sim nws. Yog tias nws tsis yog, cais thiab rov txuas cov hlau lead thiab cathode/anode kom rov sim dua. Yog tias koj lub LED tsis ci, nws yuav raug hlawv lossis puas.
