2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Hauv cov lus qhia no peb tham txog LED - Lub Teeb Emitting Diodes thiab peb yuav txuas lawv li cas yog tias peb muaj ntau chav nyob. Nov yog ib zaj lus qhia kuv xav kom kuv paub txij thaum pib vim tias rov qab thaum kuv pib tinkering nrog cov khoom siv hluav taws xob Kuv tau tsim ob peb txoj haujlwm nrog LEDs uas cia hais tias tuaj yeem ua tau zoo dua yog tias kuv paub cov khoom kuv yuav nthuav qhia hauv cov lus qhia no.

Kauj ruam 1: Saib Video

Cov vis dis aus piav qhia cov txheej txheem sib txuas sib txawv nrog lawv qhov zoo thiab qhov tsis zoo, yam uas kuv tau kawm thaum ua kuv tus kheej yuam kev. Nws muaj cov qauv piv txwv thiab txhua yam tau piav qhia nrog cov lus yooj yim kom txhua tus tuaj yeem nkag siab. Cov yog qhov hloov maj mam uas muaj nyob hauv cov vis dis aus uas peb tau tso tawm los ntawm cov lus qhia no rau qhov yooj yim.

Kauj Ruam 2: Xeem Cov Khoom Uas Xav Tau

Yog tias koj npaj tsim cov phiaj xwm nrog LEDs, koj yuav xav tau qee cov LEDs:-) Koj yuav muaj qee qhov tab sis yog tias koj xav tau qee qhov ntxiv koj tuaj yeem tau txais kev pom zoo zoo los ntawm kev xaj khoom siv ntau yam los ntawm ebay lossis aliexpress. Cov khoom siv sib txawv no tuaj yeem sib txawv me me thiab cov duab, koj tuaj yeem pom lawv nrog SMD LEDs lossis Los Ntawm Qhov Hau LEDs tab sis ib yam yog qhov tseeb, lawv yuav muaj cov xim sib txawv LEDs, qee zaum txawm tias sib txawv me me.

Kuv muaj ntau yam SMD LED hauv ob qhov ntau thiab tsawg 0603, 0805 thiab tsib xim: liab, ntsuab, xiav, daj, dawb vim yog qhov ntau thiab tsawg thiab xim uas kuv nquag siv hauv kuv cov phiaj xwm. Kuv muaj lwm yam khoom siv sib txawv rau ntawm qhov taub LEDs hauv 3mm thiab 5mm qhov ntau thiab tsawg hauv tsib xim: liab, ntsuab, xiav, daj, dawb.

Nov yog qee qhov txuas mus rau qhov twg koj tuaj yeem pom cov khoom siv sib txawv:

• Amazon: Cov Khoom Siv SMD LED, Los Ntawm Qhov Khoom LED.
• Aliexpress: Cov Khoom Siv SMD LED, Los Ntawm Qhov Khoom LED.
• Ebay: Cov Khoom Siv SMD LED, Los Ntawm Qhov Khoom LED.

Thaum koj tab tom xaj cov LEDs koj kuj tseem yuav xav tau ob peb yam cuab yeej xws li cov hlau txuas lossis cov ntsia hlau teeb. Kuv pom zoo TS100 cov hlau txuas thiab Xiaomi Wiha Screwdriver Kit. Ob yam khoom no muaj tus nqi zoo/piv zoo:

• Bangood: TS100 Soldering Hlau
• Banggood: Xiaomi Wiha Screwdriver Kit
• Aliexpress: TS100 Soldering Hlau
• Aliexpress: Xiaomi Wiha Screwdriver Kit

Kauj Ruam 3: Mus Rau Qhov Hluav Taws Xob thiab Mus Ntxiv Tam Sim No

Cia peb pib los ntawm kev tham txog kev siv hluav taws xob rau pem hauv ntej thiab tam sim no mus rau tom ntej, cov no yog ob qho piv txwv uas koj xav paub. Yog li LED yog lub diode uas tso tawm lub teeb nyob rau qee qhov xwm txheej. Nws yuav muaj qhov hluav taws xob rau pem hauv ntej uas yog qib uas lub diode pib ua. Wb coj piv txwv ib qho ntsuab LED uas ib txwm muaj qhov txuas hluav taws xob txog 1.9V. LED yuav pib ua thaum qhov hluav taws xob hla nws qhov anode thiab cathode tsawg kawg 1.9V. Yog li yog tias koj txuas 1.5V qhov hluav taws xob qhov hluav taws xob rau cov LED no nws yuav tsis ua, nws yuav tsis qhib. Yog tias koj thov piv txwv 3V nws yuav pib ua, LED yuav qhib.

Thaum nws pib ua tus LED yuav cia qhov tam sim no hla tab sis yog tias tsis muaj ib yam dab tsi los txwv qhov tam sim no, nws yuav txuas ntxiv mus ntxiv, tshaj qhov ntsuas nyob rau tam sim no, kev sib tshuam hauv LED yuav pib yaj, ua rau LED puas. Yog li ntawd yog vim li cas peb thiaj muaj qhov ntsuas hu ua rau tam sim no. Cov chaw tsim khoom ntawm LED yuav ua tus yam ntxwv thiab lawv yuav hais txog qhov tam sim no rau yav tom ntej uas nws muaj kev nyab xeeb los khiav cov LED yam tsis tau rhuav tshem nws. Tus nqi raug rau LED rau tam sim no yuav yog 20mA. Qee lub sij hawm yog tias koj xav tau ceev faj ntxiv koj tuaj yeem tsim lub Circuit Court nrog cov npoo muaj kev nyab xeeb Nws yog qhov kev coj ua zoo kom tawm ntawm 25% cov npoo thiab mus qis dua qhov ntsuas tam sim no yog tias daim ntawv thov tso cai rau nws. Tshwj xeeb tshaj yog rau qhov ntsuas me me LED koj yuav tsis xav tau mus rau qhov ntsuas tam sim no.

Kauj Ruam 4: Txwv Tam Sim No Nrog Tus Tiv Thaiv

Yog li txhawm rau txwv qhov tam sim no, thiab zam kev hla mus rau qhov tshwj xeeb rau tam sim no peb tuaj yeem ntxiv tus tiv thaiv hauv peb qhov Circuit. Txhawm rau xam cov resistor peb yuav tsum siv ob qhov ntsuas tau hais ua ntej: rau pem hauv ntej qhov hluav taws xob thiab tam sim no rau yav tom ntej nrog rau qhov muab hluav taws xob rau peb qhov Circuit Court.

Peb paub tias LED yuav poob 1.9V thaum tus tiv thaiv yuav tsum tso qhov seem 1.1V mus txog rau peb cov khoom siv hluav taws xob. Paub txog tam sim no tam sim no ntawm LED yog 20mA, peb tuaj yeem suav tus nqi ntawm tus tiv thaiv siv txoj cai ohms. R = U / I thiab hauv peb qhov xwm txheej U yog 1.1V faib los ntawm 20mA, ua rau 55 ohms.

Kauj Ruam 5: Txuas LEDs hauv Parallel

Raws li koj tuaj yeem pom nws yooj yim zoo nkauj los txwv qhov tam sim no thiab tsav ib qho LED, tab sis yuav ua li cas yog tias peb xav tau LEDs ntau dua?

Peb tuaj yeem txuas lawv ua ke thiab siv tib tus tiv thaiv kom txwv qhov tam sim no tab sis peb ua rau qee qhov teeb meem. Ua ntej vim muaj kev hloov pauv hauv cov txheej txheem tsim khoom, txhua LED yuav muaj qhov sib txawv me ntsis rau qhov hluav taws xob, qhov no txhais tau tias nws yuav kos qhov sib txawv me me tam sim no uas tuaj yeem ua rau tsis pom kev tsis zoo lossis txawm tias tsis ua haujlwm ntawm LED yog tias nws tau tsav dhau qhov tshwj xeeb tam sim no.

Hauv cov ntawv thov niaj hnub zoo li piv txwv tso saib lub teeb pom kev nws yog qhov tseem ceeb heev kom muaj lub teeb pom kev thoob plaws txhua lub LEDs. Yog li nws zoo dua kom tsis txhob txuas LEDs ua ke.

Kauj Ruam 6: Txuas LEDs hauv Series

Txoj hauv kev zoo tshaj los txuas ntau lub LEDs kom muaj tib txoj kev tsav tam sim no txhua lub LED yuav nyob ua ke. Koj yuav txuas 5 LEDs uas peb tau muaj ua ntej hauv kab ntawv thiab tsav lawv nrog qhov hluav taws xob tsis tu ncua, ib yam li ua ntej txwv qhov tam sim no nrog tus tiv thaiv. Thiab koj yuav xav tias daws teeb meem tab sis qhov teeb meem tsuas yog ib nrab tau daws vim yog lwm qhov cuab yeej ntawm diodes uas tseem siv rau LEDs ib yam.

Lub zog hluav taws xob tom ntej yuav txo qis nrog qhov kub nce ntxiv. Yog tias lub zog hluav taws xob poob qis, qhov tam sim no yuav nce ntxiv, ua kom sov LED ntau dua. Thiab muaj lwm qhov cuab yeej uas peb yuav tsum tau paub tawm ntawm qhov nkhaus nthuav tawm ntawm qhov hluav taws xob rau pem hauv ntej thiab mus rau tam sim no. Qhov no qhia peb tias nrog kev hloov pauv me me rau qhov hluav taws xob rau pem hauv ntej peb tau txais kev hloov pauv loj nyob rau yav tom ntej tam sim no thiab qhov no tuaj yeem ua rau LED tsis ua haujlwm vim cua sov khiav tawm.

Yog li txoj hauv kev peb daws qhov teeb meem no yog los ntawm kev siv qhov tam sim no tsis tu ncua. Hnub no muaj ntau qhov kev sib txuas tshwj xeeb tshaj yog tsim los rau kev tsav LEDs nrog qhov tam sim no vim tias qhov zoo tau meej. Ib tus tuaj yeem sib cav tias yog tias koj muaj LEDs nyob rau hauv, yog tias ib qho ntawm lawv ua tsis tiav, tag nrho txoj hlua yuav tsis ua haujlwm thiab qhov ntawd yog qhov tseeb los ntawm qhov hluav taws xob taw tes tab sis hauv kev coj ua, LEDs tau dhau los ua kev ntseeg tau tias yog tias lub Circuit Court raug tsim muaj lub sijhawm me me ntawm LED tsis dhau qhov hais tawm lub neej

Yog li, qhov ntawd yog txhua yam, Kuv vam tias cov lus qhia no muaj txiaj ntsig yog li thov tawm lus lossis ntaus lub pob lossis zoo li tsis nyiam kom xa qee qhov lus teb rau kuv.
