Uzivavanya njani izibane zeKrisimesi eziLed ngeMultimeter?

Kutheni uvavanya izibane zeKrisimesi ze-LED ngeMultimeter?

Izibane zeKrisimesi ze-LED ziye zanda kakhulu ngenxa yokusebenza kwazo kwamandla, ukuqina, kunye nemibala ecacileyo. Nangona kunjalo, njengaso nasiphi na isixhobo sombane, ngamanye amaxesha banokufumana imiba okanye ukungasebenzi kakuhle. Nokuba ungumnikazi wendlu okanye umhombisi oqeqeshiweyo, kubalulekile ukwazi ukuvavanya izibane zeKrisimesi ze-LED nge-multimeter ukuchonga naziphi na iingxaki kunye nokuqinisekisa ukuba zisebenza ngokufanelekileyo. Kweli nqaku, siya kukukhokela kwinkqubo yokusebenzisa i-multimeter ukuvavanya izibane zakho zeKrisimesi ze-LED, inyathelo ngesinyathelo.

Ukuvavanya izibane zeKrisimesi ze-LED: Yintoni oya kuyidinga

Ngaphambi kokuba singene kwinkqubo yovavanyo, masiqinisekise ukuba unazo izixhobo eziyimfuneko kunye nezixhobo. Nantsi into oza kuyidinga:

1. I-Multimeter: I-multimeter sisixhobo esibalulekileyo sokuvavanya iimpawu zombane zezixhobo ezahlukeneyo. Qinisekisa ukuba une-multimeter ethembekileyo ekwaziyo ukulinganisa ukuxhathisa, i-voltage, kunye nokuqhubeka.

2. Izibane zeKrisimesi ze-LED: Ewe, uya kufuna izibane zeKrisimesi ze-LED ofuna ukuzivavanya. Qokelela izibane ozikrokrelayo ukuba zinempazamo okanye ufuna nje ukuqinisekisa ukusebenza kwazo.

3. Izixhobo zoKhuseleko: Kuhlala kubalulekile ukubeka phambili ukhuseleko xa usebenza ngezixhobo zombane. Nxiba iiglavu zerabha kunye nezibuko zokhuseleko ukuze uzikhusele kuzo naziphi na iingozi ezinokubakho.

Ngoku ukuba unezixhobo ezifunekayo kunye nezixhobo, masiqhubele phambili kumanyathelo aneenkcukacha zokuvavanya izibane zeKrisimesi ze-LED nge-multimeter.

Inyathelo 1: Ukuseta iMultimeter

Ngaphambi kokuqala inkqubo yovavanyo, kubalulekile ukuqinisekisa ukuba i-multimeter isetwe ngokuchanekileyo. Nantsi indlela yokwenza:

1. Vula i-multimeter kwaye ukhethe ukuchasana (Ω) useto. Uninzi lwee-multimeters zinodayalo olusebenzayo olwahlukileyo lwemilinganiselo eyahlukeneyo, ke fumana indawo yokuchasa kwidayili.

2. Beka uluhlu kwixabiso eliphantsi lokumelana. Olu seto luya kunika ufundo oluchanekileyo xa uvavanya izibane ze-LED.

3. Qinisekisa ukuba i-multimeter yakho ine-continuity tester eyakhelweyo. Uvavanyo oluqhubekayo lunceda ukuchonga nayiphi na ikhefu kwisekethe. Ukuba i-multimeter yakho inalo mboniso, yivule.

Inyathelo 2: Ukuvavanya izibane ze-LED zokuQhubeleka

Ukuvavanyelwa ukuqhubeka kukuvumela ukuba uchonge nakuphi na ukuphuka komzimba okanye ukuphazamiseka kwisekethe yombane yezibane zakho zeKrisimesi ze-LED. Nantsi indlela yokuqhuba:

1. Khupha izibane ze-LED kuwo nawuphi na umthombo wamandla ukuqinisekisa ukhuseleko lwakho.

2. Thatha izikhokelo ezimbini ze-probe ye-multimeter yakho kwaye uchukumise enye ikhokelela kucingo lobhedu kwelinye icala lomtya we-LED, kwaye enye ikhokelela kwintambo kwelinye icala. Ukuba umvavanyi wokuqhubekeka uvuliwe, kufuneka uve i-beep okanye ubone ukufunda kufutshane nokumelana ne-zero kwi-multimeter display. Oku kubonisa ukuba isiphaluka sigqityiwe kwaye akukho zikhefu.

3. Ukuba awuyiva i-beep okanye ukufundwa kokuchasana kuphezulu kakhulu, hambisa i-probe ikhokelela kumtya, ukhangele kwiindawo ezahlukeneyo, ude ufumane ikhefu apho isiphaluka siphazamiseka. Oku kunokuba ngenxa yocingo olonakeleyo okanye i-LED engalunganga.

Inyathelo lesi-3: Ukujonga ukusebenza kweVoltage

Nje ukuba ugqibezele ukuqhubeka kwezibane zakho zeKrisimesi ze-LED, lixesha lokujonga ukusebenza kwazo kwamandla ombane. Landela la manyathelo:

1. Guqula i-multimeter yakho yokudayela kwi-voltage (V). Ukuba ineendlela ezininzi zombane, yibeke kuluhlu olusondeleyo kumbane olindelekileyo wezibane ze-LED. Umzekelo, ukuba unoluhlu lwezibane ezilinganiselwe kwii-volts ezili-12, khetha uluhlu lwe-20-volt.

2. Faka izibane ze-LED kwaye uqinisekise ukuba zixhunyiwe kumthombo wamandla.

3. Chukumisa iprobe ephozithivu (ebomvu) ukuya kwitheminali okanye ucingo kwizibane ze-LED. Emva koko, bamba i-negative (emnyama) probe ekhokelela kwi-terminal ethabathayo okanye ucingo.

4. Funda i-voltage eboniswe kwi-multimeter. Ukuba ingaphakathi koluhlu olulindelekileyo (umzekelo, i-11V-13V yezibane ze-12V), izibane zisebenza ngokufanelekileyo. Ukuba ukufundwa kombane kusezantsi kakhulu okanye kuphezulu kunoluhlu olulindelekileyo, kusenokubakho umba ngobonelelo lwamandla okanye izibane ngokwazo.

Inyathelo lesi-4: Ukulinganisa ukuchasa

Uvavanyo lokuchasa lunokunceda ukuchonga iingxaki ngee-LED ezithile, ezinjengezo ezinokuthi zibe nempazamo okanye zitshiswe. Nantsi indlela yokulinganisa ukuxhathisa:

1. Guqula ukucofa kwi-multimeter yakho kuxhathiso (Ω) useto.

2. Yahlula i-LED ofuna ukuyivavanya kuyo yonke intambo. Khangela iingcingo ezimbini eziqhagamshelwe kwi-LED ofuna ukuyilinganisa.

3. Chukumisa enye iprobe ye-multimeter ikhokelela kwintambo nganye eqhagamshelwe kwi-LED. Umyalelo awukhathali njengoko i-multimeter iya kubona ukuxhathisa kungakhathaliseki.

4. Jonga ukuxhathisa ukufunda kwi-multimeter display. Ukuba ukuchasana kusondele kwi-zero, i-LED inokuthi isebenze ngokuchanekileyo. Nangona kunjalo, ukuba ukufundwa akunasiphelo okanye kuphezulu kakhulu kunokuba bekulindelwe, i-LED inokuba mbi kwaye kufuneka itshintshwe.

Inyathelo lesi-5: Ukuchonga Ingxaki

Emva kokulandela amanyathelo angaphambili, usenokuba uye wadibana nemiba ethile. Makhe sixoxe ngeengxaki ezinokwenzeka kunye nezisombululo zazo:

1. Ukuba awuvanga ibhiphu xa uvavanyelwa ukuqhubeka okanye ukuxhathisa ukufunda bekuphezulu kakhulu, kusenokwenzeka ukuba unocingo olwaphukileyo. Hlola ngokucophelela indawo apho kwenzeka khona ikhefu kwaye, ukuba kunokwenzeka, lungisa ucingo usebenzisa i-tape yombane okanye i-soldering.

2. Ukuba ukufundwa kwe-voltage kuphezulu kakhulu okanye kuphantsi kunokuba kulindelwe, unokuba nengxaki yokubonelela ngombane. Qinisekisa ukuba umthombo wamandla uhambelana neemfuno zombane kwizibane ze-LED kwaye ucinge ngokutshintsha unikezelo lwamandla xa kuyimfuneko.

3. Ukuba i-LED nganye ibonisa ukuxhathisa okungapheliyo okanye ufundo oluphezulu kakhulu lokumelana, inokuba nempazamo okanye itshiswe. Ukutshintsha i-LED enesiphene kunokusombulula lo mba.

Ukuqukumbela, ukuvavanya izibane zeKrisimesi ze-LED nge-multimeter yinkqubo ethe ngqo ekuvumela ukuba uchonge kwaye ulungise nayiphi na imiba enokuthi izibane zakho zibe nazo. Ngokulandela la manyathelo achazwe ngasentla, ungalonwabela ixesha leholide elikhanyiswe kakuhle ngelixa uqinisekisa ukhuseleko kunye nokusebenza kwezibane zakho zeKrisimesi ze-LED. Khumbula ukuhlala ubeka phambili ukhuseleko xa usebenza ngezixhobo zombane kwaye usebenzise inkathalo xa ujongene neengcingo eziveziweyo okanye imithombo yamandla.

Isishwankathelo

Ukuvavanya izibane zeKrisimesi ze-LED nge-multimeter kubalulekile ekuqinisekiseni ukusebenza kwazo okufanelekileyo kunye nokuchonga naziphi na iimpazamo okanye imiba. Ngokusebenzisa i-multimeter ukuvavanya ukuqhubeka, ukusebenza kombane, kunye nokumelana, unokugqiba ukuba izibane zakho ze-LED zisebenza ngokuchanekileyo na. Ukuba kuvela naziphi na iingxaki, ezifana neengcingo ezaphukileyo, imiba yonikezelo lwamandla, okanye ii-LED ezingalunganga, ngoku unolwazi lokuzilungisa. Lonwabela ixesha leholide elingenazinkathazo kunye nezibane ezikhanyayo zeKrisimesi ze-LED, ngenxa yamandla e-multimeter.
