Ungawavivinya Kanjani Amalambu KaKhisimusi Ama-Led Nge-Multimeter?

Kungani Uhlola Izibani zikaKhisimusi ze-LED nge-Multimeter?

Izibani zikaKhisimusi ze-LED sezithandwa kakhulu ngenxa yokusebenza kahle kwamandla, ukuqina, nemibala egqamile. Nokho, njenganoma iyiphi idivayisi kagesi, ngezinye izikhathi bangathola izinkinga noma ukungasebenzi kahle. Kungakhathaliseki ukuthi ungumnikazi wendlu noma umhlobisi ochwepheshe, kubalulekile ukwazi ukuthi ungazihlola kanjani izibani zikaKhisimusi ze-LED usebenzisa i-multimeter ukuze uhlonze noma yiziphi izinkinga futhi uqinisekise ukuthi zisebenza kahle. Kulesi sihloko, sizokuqondisa ngenqubo yokusebenzisa i-multimeter ukuhlola izibani zakho zikaKhisimusi ze-LED, isinyathelo ngesinyathelo.

Ukuhlola Izibani zikaKhisimusi ze-LED: Okuzodinga

Ngaphambi kokuthi sicwilise enqubweni yokuhlola, asiqinisekise ukuthi unamathuluzi adingekayo nezinto zokusebenza. Nakhu ozodinga:

1. I-Multimeter: I-multimeter iyithuluzi elibalulekile lokuhlola izakhiwo zikagesi zamadivayisi ahlukahlukene. Qiniseka ukuthi une-multimeter ethembekile ekwazi ukukala ukumelana, i-voltage, nokuqhubeka.

2. Izibani zikaKhisimusi ze-LED: Yebo, uzodinga izibani zikaKhisimusi ze-LED ofuna ukuzihlola. Qoqa izibani osola ukuthi zinephutha noma ufuna nje ukuqinisekisa ukusebenza kwazo.

3. Izisetshenziswa Zokuphepha: Kuhlale kubalulekile ukubeka ukuphepha kuqala lapho usebenza ngezinto zikagesi. Gqoka amagilavu ​​enjoloba kanye nezibuko zokuphepha ukuze uzivikele kunoma yiziphi izingozi ezingaba khona.

Manje njengoba usunamathuluzi nezinto zokusebenza ezidingekayo, ake siqhubekele ezinyathelweni ezinemininingwane zokuhlola izibani zikaKhisimusi ze-LED nge-multimeter.

Isinyathelo 1: Ukusetha i-Multimeter

Ngaphambi kokuqala inqubo yokuhlola, kubalulekile ukuqinisekisa ukuthi i-multimeter isethwe ngendlela efanele. Nansi indlela yokwenza:

1. Vula i-multimeter bese ukhetha ukulungiselelwa kokumelana (Ω). Ama-multimeters amaningi anokudayela okuhlukile kokusebenza kwezilinganiso ezihlukene, ngakho-ke thola ukulungiselelwa kokumelana kokudayela.

2. Setha ububanzi kunani eliphansi lokumelana. Lesi silungiselelo sizonikeza ukufundwa okunembe kakhulu lapho kuhlolwa izibani ze-LED.

3. Thola ukuthi ingabe i-multimeter yakho inesihloli sokuqhubeka esakhelwe ngaphakathi. Ukuhlola ukuqhubeka kusiza ukukhomba noma yikuphi ukuhlukana kwesekethe. Uma i-multimeter yakho inalesi sici, yivule.

Isinyathelo sesi-2: Ukuhlola Izibani ze-LED ukuze Ziqhubeke

Ukuhlolela ukuqhubeka kukuvumela ukuthi ukhombe noma yikuphi ukuphuka noma ukuphazamiseka kumjikelezo kagesi wezibani zakho zikaKhisimusi ze-LED. Nansi indlela yokuqhubeka:

1. Khipha izibani ze-LED kunoma yimuphi umthombo wamandla ukuze uqinisekise ukuphepha kwakho.

2. Thatha imikhondo emibili ye-probe ye-multimeter yakho bese uthinta umthofu owodwa uye ocingweni lwethusi ekugcineni kwentambo ye-LED, bese enye uyiholele ocingweni ngakolunye uhlangothi. Uma isihloli sokuqhubeka sivuliwe, kufanele uzwe ibhiphu noma ubone ukufunda eduze nokumelana neqanda kusibonisi samamitha amaningi. Lokhu kubonisa ukuthi isifunda siphelile futhi azikho iziqephu.

3. Uma ungezwa ibhiphu noma ukufundwa kokumelana kuphezulu kakhulu, hambisa umkhondo we-probe entanjeni, uhlole ezindaweni ezihlukahlukene, uze uthole ikhefu lapho isekethe iphazamiseka khona. Lokhu kungase kube ngenxa yocingo olulimele noma i-LED engalungile.

Isinyathelo sesi-3: Ukuhlola Ukusebenza Kwe-Voltage

Uma usunqume ukuqhubeka kwezibani zakho zikaKhisimusi ze-LED, sekuyisikhathi sokuhlola ukusebenza kwawo kwamandla kagesi. Landela lezi zinyathelo:

1. Guqula ukudayela kwakho kwe-multimeter ku-voltage (V). Uma inamabanga kagesi amaningi, isethe ebangeni eliseduze nomthamo olindelekile wezibani ze-LED. Isibonelo, uma uneyunithi yezinhlamvu zezibani ezilinganiselwe ngamavolthi angu-12, khetha ububanzi obungu-20-volt.

2. Xhuma izibani ze-LED futhi uqinisekise ukuthi zixhunywe kumthombo wamandla.

3. Thinta umthofu ophozithivu (obomvu) oya kutheminali ephozithivu noma intambo ezibanini ze-LED. Bese, thinta uphenyo olunegethivu (olumnyama) oluya kutheminali enegethivu noma ocingweni.

4. Funda i-voltage evezwe ku-multimeter. Uma ingaphakathi kwebanga elilindelekile (isb, i-11V-13V yezibani ze-12V), izibani zisebenza kahle. Uma ukufundwa kwamandla kagesi kuphansi kakhulu noma kungaphezulu kwebanga elilindelekile, kungase kube nenkinga ngokunikezwa kwamandla noma izibani ngokwazo.

Isinyathelo sesi-4: Ukulinganisa Ukumelana

Ukuhlolwa kokumelana kungasiza ekuboneni izinkinga ngama-LED athile, njengalawo okungenzeka abe namaphutha noma ashiswe. Nansi indlela yokukala ukumelana:

1. Shintsha ukudayela ku-multimeter yakho kuya kulungiselelo lokumelana (Ω).

2. Hlukanisa i-LED ofuna ukuyihlola kuyo yonke iyunithi yezinhlamvu. Thola izintambo ezimbili ezixhunywe ku-LED ofuna ukuzikala.

3. Thinta umthofu we-multimeter probe eyodwa kucingo ngalunye oluxhunywe ku-LED. I-oda alinandaba njengoba i-multimeter izobona ukumelana noma ngabe.

4. Hlola ukufundwa kokumelana kusibonisi se-multimeter. Uma ukumelana kusondele ku-zero, kungenzeka ukuthi i-LED isebenza kahle. Kodwa-ke, uma ukufundwa kungapheli noma kuphakeme kakhulu kunalokho obekulindelwe, i-LED ingase ibe yimbi futhi idinga ukushintshwa.

Isinyathelo sesi-5: Ukuhlonza Inkinga

Ngemva kokulandela izinyathelo ezedlule, kungenzeka ukuthi uhlangabezane nezinkinga ezithile. Ake sixoxe ngezinkinga ezingaba khona nezisombululo zazo:

1. Uma ungezwanga ibhiphu ngenkathi ukuhlola ukuqhubeka noma ukufundwa kokumelana bekuphezulu kakhulu, kungenzeka ukuthi unocingo oluphukile. Hlola ngokucophelela indawo lapho kuphuka khona futhi, uma kungenzeka, lungisa ucingo usebenzisa i-tape kagesi noma i-soldering.

2. Uma ukufundwa kwamandla kagesi kuphezulu kakhulu noma kuphansi kunalokho obekulindelwe, ungase ube nenkinga yokunikezwa kwamandla kagesi. Qinisekisa ukuthi umthombo wamandla ufana nezidingo ze-voltage zamalambu e-LED futhi ucabange ukushintsha indawo yamandla uma kudingeka.

3. Uma i-LED ngayinye ibonisa ukumelana okungapheli noma ukufunda ukumelana okuphezulu kakhulu, kungase kube iphutha noma kushiswe. Ukushintsha i-LED engasebenzi kungase kuxazulule le nkinga.

Sengiphetha, ukuhlola izibani zikaKhisimusi ze-LED nge-multimeter kuyinqubo eqondile ekuvumela ukuthi ukhombe futhi ulungise noma yiziphi izinkinga okungenzeka izibani zakho zibe nazo. Ngokulandela izinyathelo ezichazwe ngenhla, ungajabulela inkathi yeholide ekhanyiswe kahle kuyilapho uqinisekisa ukuphepha nokusebenza kwezibani zakho zikaKhisimusi ze-LED. Khumbula njalo ukubeka phambili ukuphepha lapho usebenza ngezinto zikagesi futhi usebenzise ukuqaphela lapho usebenza nezintambo eziveziwe noma imithombo yamandla.

Isifinyezo

Ukuhlola izibani zikaKhisimusi ze-LED nge-multimeter kubalulekile ukuze kuqinisekiswe ukusebenza kwazo okufanele nokuhlonza noma imaphi amaphutha noma izinkinga. Ngokusebenzisa i-multimeter ukuhlola ukuqhubeka, ukusebenza kwe-voltage, nokumelana, unganquma ukuthi izibani zakho ze-LED zisebenza kahle yini. Uma kuphakama izinkinga, njengezintambo eziphukile, izinkinga zokuhlinzekwa kwamandla, noma ama-LED angalungile, manje usunolwazi lokuzixazulula. Jabulela inkathi yamaholide engenazinkathazo ngezibani zikaKhisimusi ezikhanyiswe kahle ze-LED, ngenxa yamandla e-multimeter.
