Indlela ukuxhuma emapheshana LED emotweni?

Muva nje, ngo-izakhi ukukhanya, ezifana eteyipini, ngokuvamile sisetshenziswa emotweni Tuning. Zisetshenziswa ukushayela backlight, phansi ingaphakathi imoto. Mayelana nendlela ukuxhuma emapheshana LED e umshini kahle auto abasebenzi lobuchwepheshe, kodwa uma unquma ukwenza bebodwa, kufanele ufunde le mininingwane elandelayo ewusizo. Ufuna nje uqaphele ukuthi obalulekile plus emapheshana nge LED - wukuthi uzilungiselele ngangokunokwenzeka ukuze afeze ukufakwa yabo. Ngaphandle kwalokho, abawubheki ngempumelelo kuphela, kodwa futhi kukhona ukonga, okuhlala ngokwedlulele (oda amahora ayizinkulungwane 5 ukusebenza) futhi zakhiwe impahla amanzi.

Isinyathelo 1. Indlela ukuxhuma emapheshana LED: Khetha indawo ukufakwa nobude tape

Okokuqala, unqume kulokho ingxenye emshinini wakho ufuna ukufaka izibani LED. Khona-ke kuyodingeka ukunquma ubude tape ukuthi okudingayo. Khumbula ukuthi lo mkhiqizo kungenziwa kuphela besika ngezikhawu amaningi (isibonelo, i-tape SMD 3528 Q60 inqanyulwa zonke ngamasentimitha amahlanu). Ekubaleni lokhu obuphelele okumelwe icatshangelwe. Futhi, kufanele wazi ukuthi ububanzi emapheshana ka LED ingeqi ngamasentimitha amabili ngesikhathi ukushuba amamilimitha angu ezimbili, futhi ubude ejwayelekile yemigoqo ethile eminyangweni kahulumeni e esondweni - amamitha amahlanu.

Isinyathelo 2. Indlela ukuxhuma emapheshana LED: indlela ukukhetha i-tape

Kusukela lokho, yini endaweni yokumiswa ukhetha incike onjani iribhoni udinga ukuthenga. Ngakho, ngenxa kwasemuva esetshenziswa ezinzulwini LED strip yezinto ezibonakalayo. manzi, lapho sisetshenziswa enamathela esobala abicah. Leteyipu kungenziwa kukhethwe njengoba ezinombala ofanayo futhi ezimibalabala, enikezwe LED emithathu umbala. Inketho yokugcina yayithandwa kakhulu ngoba ngenxa ukuxuba yalezi ngemibala emithathu itheyiphu uyakwazi likhipha yimuphi umbala futhi luhlaza.

Ukugqamisa ngaphansi hood, uzodinga oluhlehlela iribhoni LED. Futhi ukuze azenze zikhanye phansi izihlalo eziphambili imoto yakho, uzodinga tape LED base self-Yesigcilikisha. Ngokuvamile, strip LED, ngenxa yobude bayo nokuvumelana nezimo, kungase kufakwe i-nomaphi lapho amehlo akho engqondo kuzovumela.

Isinyathelo 3: Indlela ukuxhuma emapheshana LED: khetha ugesi

Ngokusekelwe yokuthi strip LED kukhona ezahlukene voltage (5, 12 noma 24), udinga ukuthenga ezifanele amandla ibhande ugesi. Ukuze wenze lokhu, kungcono nochwepheshe ukuze unciphise ingozi sokuthenga akuphumelelanga.

Isinyathelo 4. Indlela ukuxhuma emapheshana LED: afeze ukufakwa kanye uxhumano tape

Uma ngiye ngazuza zonke izimpahla ezidingekayo, une ukulungiselela surface ekhethelwe obandayo strip LED. Ukukhweza indawo kufanele degreased ngokucophelela (isibonelo, ngotshwala). Ngokuvamile, kungcono kakhulu uma ebusweni akhethiwe luyoqina, ukuthi kusiza ukuvimbela ukulimala tape ye PCB. Esimweni lapho uzobe ukugibela ebusweni metal noma yimuphi omunye conductive, itheyiphu nangokuvikela.

Uma tape ayidingi izihlahla, ke aqhubeke ngokushesha ukufakwa kwalo. Ngosizo isendlalelo ingcina, elitholakala kumugqa ohlangothini reverse LED, kulula kakhulu ukukwenza. Ukususa enamathela okuvikela ukuze ebusweni cindezela ibhande.

Manje kudingeka ukuba uxhume tape ukuze isilawuli ugesi. Lokhu kwenziwa ngosizo izintambo eteyipini. Njalo lapho ungenela has ukuqokwa siqu (G, B, V, + R) endleleni conductive. Hook (ngokuvumelana polarity) ukuze imibono emine iyatholakala kwi isilawuli ne notation efanayo (G, B, V, + R).

Manje, indlela ukuxhuma ugesi kunethiwekhi (220) izintambo ezimbili kuya nezixhumi n- futhi L +. Xhuma "plus" phezu iyunithi "plus" ku isilawuli "lokususa", ngokulandelana, kuya 'lokususa ". I polarity of the voltage akukwazi udidekile noma kunjalo, njengoba lokhu kungadala ukulimala umonakalo tape imishini.

Manje usufundile indlela ukuxhuma emapheshana LED emotweni. Futhi lapho ucabanga yokuthi namuhla ukuthengwa kwezimpahla ezifana ethengekayo cishe zonke umnikazi wemoto, unganqikazi ofinyelela eqophelweni eliseduze of ukudayiswa kwemikhiqizo yezimoto, noma ukuvula ikhasi elihambisana esitolo online.

Futhi inhlanhla kuwe endleleni!
