Ukuchithwa kokushisa kuwathinta kangakanani ukukhanya okuphezulu kwe-LED
Ngenxa yokushoda kwamandla emhlabeni wonke kanye nokungcoliswa kwemvelo, isibonisi se-LED sinendawo ebanzi yohlelo ngenxa yezimpawu zakhona zokonga amandla nokuvikelwa kwemvelo.Emkhakheni wokukhanyisa, ukusetshenziswa kwemikhiqizo ekhanyayo ye-LED kudonsa ukunaka komhlaba.Genener...Funda kabanzi -
Ukuhlaziywa kwenzuzo kanye nezici zesakhiwo sezibani ze-LED
Isakhiwo sesibani se-LED sihlukaniswe ikakhulukazi izingxenye ezine: ukwakheka kwesistimu yokusabalalisa ukukhanya, ukwakheka kwesistimu yokukhipha ukushisa, isifunda sokushayela kanye nemishini yokuzivikela / yokuzivikela.Uhlelo lokusabalalisa ukukhanya lwakhiwe ngebhodi lesibani le-LED (umthombo wokukhanya) / ukushisa ukushisa ...Funda kabanzi -
Isici sokuzivikela sesekethe yokukhanyisa i-LED: i-varistor
Umthamo wamanje we-LED ukhuphuka ngenxa yezizathu ezahlukahlukene ezisetshenziswayo.Ngalesi sikhathi, izinyathelo zokuzivikela zidinga ukuthathwa ukuze kuqinisekiswe ukuthi i-LED ngeke yonakaliswe ngoba ukwanda kwamanje kudlula isikhathi esithile kanye nobukhulu.Ukusebenzisa amadivaysi okuvikela isekethe kuyisivikelo esiyisisekelo futhi esongayo...Funda kabanzi -
Isinyathelo esilandelayo sokunikezwa kwamandla ezimo eziphuthumayo ze-LED ukuhlanganiswa nobuhlakani
Njengamanje, umnotho womhlaba ukhombisa umfutho omuhle, futhi imboni ye-LED nayo ikhombisa ukugxuma okungakaze kubonwe ngaphambili.Ngaphansi kokwakhiwa kwedolobha elihlakaniphile, amabhizinisi aholayo abamba leli thuba futhi aqhubeke nokusungula nokuthuthukisa.Ukuthuthuka ngokushesha kwemboni nakho kuxhumene ne-L...Funda kabanzi -
Ngokuqhubeka okuqhubekayo kobuchwepheshe bokukhanyisa kwe-LED, ukukhanyisa okunempilo kuzoba indawo elandelayo yomkhakha
Eminyakeni engaphezu kweshumi edlule, abantu abaningi bebengeke bacabange ukuthi ukukhanya nempilo bekuzohlobana.Ngemuva kweminyaka engaphezu kweshumi yentuthuko, imboni yezibani ze-LED iye yanda kusukela ekuphishekeleni ukusebenza kahle kokukhanya, ukonga amandla kanye nezindleko kuya esidingweni sekhwalithi yokukhanya, impilo ekhanyayo, ukukhanya ...Funda kabanzi -
