Ixhuma LED. Yini kungaba lula?

Lesi sihloko sichaza ukuthi kusetshenziswe kanjani uxhumano LED, nguyiphi imitsetfo kudingeka athobele ukuze kuqinisekiswe ukusetshenziswa ngemfanelo amadivaysi. Ukuhluka uxhumano.

Ixhuma LED. Yini kungaba lula?

Lezi zinto ezincane manje eyaziwa kabanzi. Wonke umuntu oye wezwa kuBaba futhi LED izibani, izibani, nemiklamo kanye nezinye elikhanyayo, izingubo akhazimula namathoyizi. Sinenkosi izinzuzo eziningi uma kuqhathaniswa ezivamile ukukhanya ama, kodwa kukhona izici isicelo. Ngakho kanjani udinga ukwenza uxhumano LED?

Ukuze ukusetshenziswa ngokufanele amadivaysi kudingeka ngokuqinile ukulandela izidingo ezimbalwa ezilula, bese ngeke ukuletha ababhekene nanoma iyiphi inkathazo futhi bayokhonza isikhathi eside.

Okubaluleke kakhulu - ungakhohlwa imithetho emibili eyisisekelo:

1. LED kukhona amadivayisi Semiconductor futhi abe ngendlela eyodwa conductivity, noma, ngamanye amazwi, ukuxhumana LED kufanele kwenziwe nge polarity lesifanele (njengoba uma uxhuma ibhethri kungaba ungayididanisi "+" futhi "-"). Kungenjalo, LED kungenzeka zishiswe noma ngeke kukhanye.

2. Kudivayisi elawulwa zamanje. Uyini kagesi, akudingekile ukuchaza, kodwa iqiniso lokuthi inani layo zingase zihluke, odinga ukukwazi. Inani egeleza ngokusebenzisa wesifunda kunqunywa elithile ukumelana layo. Kwenzeka okufanayo lapho uvula empompini - uma uvula kancane ke, amanzi agobhoze ukusakaza mncane, eligeleza ukumelana amanzi kampompi ezinkulu; uma uvula it ngokuphelele, amanzi agobhoze jet enamandla, ukumelana ketshezi crane amancane.

Ukuze uthole ukusebenza ilungile futhi okuqhubekayo wasekhaya kumele egeleza inani elithile zamanje, izinga kunqunywa izici LED. Uma wamanje mkhulu kakhulu, ushe iyunithi. Lokhu okulingana ethi sizozama amanzi nge ingcindezi ngokusebenzisa mncane iraba hose. Uma ingcindezi akuyona eliqinile, amanzi kuyodingeka isikhathi ukuba adabule hose, futhi konke kuzolunga. Uma inkulu kakhulu, umane hose ekuqhumeni. Kwenzeka okufanayo nge LED. Uma yamanje lidlula inani efiselekayo, ushe iyunithi.

Inani lamanje elawula ukumelana. Kuyadingeka ukuba ukhumbule ukuthi uxhumano LED ukuze umthombo voltage zingenziwa kuphela ngokusebenzisa ukumelana. Kuyini, futhi kufanele kangakanani ukumelana esetshenziselwa operation evamile LED akuwona isihloko salesi sihloko. Uma ufuna ukwenza idivayisi ukukhanya ke uthole nokubonisana ngokwanele azigcinele ukukhethwa ukumelana naye. Nokubamba kancane nokunamathisela ngomthofu yokuxhuma izici ndawonye.

Konke okungenhla kuyasebenza uma yokuxhuma amadivayisi DC umthombo voltage, okungukuthi, amabhethri, ibhethri noma into efana naleyo. Lapho izama ukuxhuma LED kunethiwekhi ekhaya, okungukuthi, AC umthombo voltage, kubalulekile ukuba ngaphezu kwalokho zisebenzisa i-diode rectifier, ungakhohlwa ngalokhu lapho Rule 1.

Nokho, kungase kube isimo lapho udinga ukusebenzisa LED eziningi kanyekanye. Kulokhu, kunezindlela ezimbili ukuqalisa le isidingo ukuphi.

Uma udinga ukuthola, isibonelo, ukukhanyisa ngaphezulu, sebenzisa uxhumano okucishe kufane nalokhu LED. Khona-ke konke Cishe efanayo, kuphela umthombo voltage ngesikhathi esifanayo ukuxhuma kumadivaysi amaningi. Ungakhohlwa ukuthi uxhumano ngamunye wabo kufanele kwenzeke ngokusebenzisa Resistor.

Uma kubalulekile ukwenza into efana nemiklamo, udinga serial uxhumano LED. Kulokhu, uhlobo olufanayo amadivaysi axhumene ukuze ixhunywe ku-lokususa odlule plus kwesikhathi. Ngenxa yalokho, sithola iketango has emikhawulweni emibili khulula - emihle nemibi. Futhi ngaleli ketanga isivele osebenza njengokuvimbelayo LED olulodwa, futhi kungenziwa exhunywe nge Resistor ukuba umthombo voltage.
