Ungaxhuma kanjani umugqa we-LED emotweni ukuze ukhanyise isiqu
Okuqukethwe
Ngaso sonke isikhathi gcina isicishamlilo kanye nekhithi yosizo lokuqala enosizo lokuqala lokulimala nokusha egaraji lapho ulungisa khona imoto yakho. Sebenza nomsizi ozokusiza uma kwenzeka ingozi.
Ukukhanyisa okungeziwe kwe-trunk ngama-diode kuwuhlobo olujwayelekile lokulungisa imoto. Ezinkundleni zokuxhumana, abashayeli bezimoto baxoxa ngokungenzeka kwalo mcimbi, bacobelelane ngolwazi mayelana nendlela yokuxhuma umugqa we-LED emotweni ukuze ukhanyise i-trunk.
Izimpawu zemichilo ye-LED
Eceleni komugqa oguquguqukayo onama-LED, amele ibhodi lesifunda eliphrintiwe, kukhona amathrekhi aphethe njengamanje, ama-transistors nama-diode adayiswa. Imichilo ye-LED ihlukile ngamapharamitha.
Usayizi wama-LED
Ukukhanyisa indawo yemithwalo, akuwona ama-diode ajwayelekile anemikhondo emide asetshenziswa, kepha ama-smd-analogues, anamaphedi okuxhumana amancane - umkhondo we-planar.
Usayizi we-LED
Ubukhulu bezibani bubethelwe ngokumaka okunezinombolo ezine. I-notation iqukethe ubude nobubanzi bama-LED ngamamilimitha ayikhulu. Isibonelo, 3228 isho 3,2x2,8 mm. Uma uwathatha mkhulu usayizi wama-semiconductors akhipha ukukhanya, ukukhanya kugqama, kukhulu ukusetshenziswa kwamandla kanye nokushisisa kwesici.
Ukuminyana
Kumitha eyodwa egijima yebhodi lesifunda eliphrintiwe, inombolo ehlukile yama-diode (ama-chips) anosayizi ofanayo angatholakala. Lokhu kuncike ekusetshenzisweni kwamandla. Ngakho-ke, ama-diode angu-60 amakwe ku-3528 imitha adla ama-watts angu-4,8, i-120 yezakhi ezifanayo endaweni efanayo "izosusa" ama-watts angu-9,6. Ngesiqu semoto, ibhodi elinesisindo sama-chips angu-120 nge-1 m lilungile.
Ngombala okhanyayo
Abanikazi bezimoto banethuba lokukhetha nokuxhuma i-diode tape yanoma yimuphi umbala nomthunzi esiqwini semoto. Cabanga ngama-nuances: awukho umbala omhlophe njengalokhu. Lo mthunzi unikeza ikristalu eluhlaza okwesibhakabhaka ehlanganiswe ne-phosphor. I-elementi ivamise ukufiphala, ngakho iribhoni elimhlophe lizoqala ukukhazimula ngokuluhlaza okwesibhakabhaka ngokuhamba kwesikhathi. Ngokusetshenziswa njalo, ama-diode alahlekelwa ukukhanya kwawo okwesithathu.
Ngesigaba sokuvikela
Zonke izinto zikagesi kufanele zivikelwe ekulimaleni kwemishini kanye nomswakama. Lapho ufunda ukuthi ungaxhuma kanjani umugqa we-LED emotweni ukuze ukhanyise i-trunk, qaphela isigaba sokuphepha, esichazwa yizinhlamvu "IP".

Indlela yokuxhuma umugqa we-LED wokukhanya kwe-trunk
Inqubo isidume ngezizathu ezimbalwa:
- kushibhile enhle;
- ungakwenza ngokwakho.
Okudingayo ukuze ufake i-backlight
Khetha indawo lapho umugqa okhanyayo uzodlula khona: phezulu, phansi, ungawubeka eduze kwama-subwoofers. Kala ubude, thenga iribhoni yombala oyifunayo.
Ukuze ufake uzodinga:
- izintambo ezibomvu nezimnyama;
- shintsha ama-switch, amatheminali kuwo nama-fuse;
- ama-clamps ukubopha i-wiring;
- ukushisa kuncipha i-cambric;
- i-rubber bushings yemigodi yezobuchwepheshe yezintambo ezidlulayo;
- i-silicone sealant;
- itheyiphu enezinhlangothi ezimbili.

Indlela yokufaka i-tape
Kuzodingeka ukuthi izintambo zidonswe endaweni yemithwalo ziyiswe kudeshibhodi, ngakho phinda osofa bangemuva.
I-algorithm yokuxhuma umugqa we-LED emotweni ukukhanyisa isiqu:
- Sika umucu ube yizicucu zobude obufunayo.
- Solder izintambo: obomvu - kuya "+", omnyama - kuya "-".
- Gcwalisa amalunga e-solder ngeglue eshisayo.
- Donsela izintambo kuswishi yokuguqula, bese usuka kuyo uthengise intambo yesibili uye ensimbi yomzimba (noma iyiphi ibhawudi izokwenza).
- Namathisela itheyiphu enezinhlangothi ezimbili ezindaweni eziqokiwe.
Ithiphu: Sebenzisa izixhumi esikhundleni sokunamathisela. Isinyathelo esilandelayo ukuxhuma umugqa we-LED emotweni ukuze ukhanyise i-trunk.
Izindlela zokuxhuma itheyiphu ye-diode emthonjeni wamandla
Kunezinketho ezimbalwa:
- Xhuma intambo ephozithivu (ebomvu) ukusuka kuma-diode uye kukhava yengxenye yemithwalo evamile.
- Uma ufuna ukukhanya kwe-trunk kukhanye ngesikhathi esifanayo nokukhanyisa kwangaphakathi, nikeza amandla ama-diode ngokukhanya kwe-dome. Kodwa ukuze usondele kuyo, kufanele ususe umugqa wophahla. Udinga ukuxhuma ne-"plus" ngemuva kwenkinobho yamandla, bese uthatha "i-minus" ensimbi yomzimba.
- Indlela elula yokuxhuma i-strip ye-LED emotweni ukuze ikhanyise i-trunk iqonde ngqo kumshini wokuthungela. Kodwa kule nguqulo, ukukhanya kuzohlala, ngisho noma ukhipha ukhiye. Ngakho-ke, faka inkinobho ehlukile ukuvala ama-diode.
- Faka i-AC resistor kuzintambo, lungisa ukukhanya kokukhanya ngayo.

Ukuphepha ngesikhathi sokufakwa nokusebenza
Gcina ukuphepha kwakho engqondweni lapho usebenza ngezinto zikagesi. Imithetho elula:
- Ungagobi, ungasonti i-tape: izindlela eziphethe njengamanje zingase ziphule.
- Ungaxhumi izintambo ngezandla ezimanzi.
- Sebenza ngamagilavu enjoloba nama-ovaroli kakotini.
- Sebenzisa amathuluzi angewona ama-conductive (izikulufa, izidladla).
- Nqamula ibhethri uma izintambo.
- Beka insimbi eshisayo e-solder endaweni ekhethekile ukuze ungashisi nge-upholstery nezindawo zepulasitiki.
- Qiniseka ukuthi isivalo se-trunk sivuleke ngokuvikelekile.
Ngaso sonke isikhathi gcina isicishamlilo kanye nekhithi yosizo lokuqala enosizo lokuqala lokulimala nokusha egaraji lapho ulungisa khona imoto yakho. Sebenza nomsizi ozokusiza uma kwenzeka ingozi.
