Ukukhethwa kwamandla okushayela ohlelo lokusebenza lokufiphalisa ibha yesibani se-LED
I-LED isetshenziswa kabanzi ezindaweni zokukhanyisa.Ngaphezu kwezinzuzo zayo eziyingqayizivele kunezindlela zokukhanyisa zendabuko, ngaphezu kokuthuthukisa izinga lempilo, ukuthuthukisa ukusebenza kahle kwemithombo yokukhanya nokwandisa impilo yesevisi yezinto zokukhanyisa, i-LED isebenzisa ukufiphala kwayo okuyingqayizivele ...Funda kabanzi -
Ukufiphala okulawulwa yi-silicon ukuze kukhanye kahle kakhulu kwe-LED
Ukukhanyisa kwe-LED sekuphenduke ubuchwepheshe obujwayelekile.Amathoshi e-LED, amarobhothi namalambu akhona yonke indawo.Amazwe akhuthaza ukushintshwa kwamalambu e-incandescent nawe-fluorescent ezindaweni zokuhlala, ezohwebo nezimboni ezinikezwa amandla amakhulu anamalambu e-LED.Kodwa-ke, uma ukukhanya kwe-LED ...Funda kabanzi -
Izinkomba eziyisithupha zokwahlulela ukusebenza komthombo wokukhanya we-LED nobudlelwano bawo
Ukwahlulela ukuthi ingabe umthombo wokukhanya we-LED uyilokho esikudingayo, ngokuvamile sisebenzisa i-sphere ehlanganisayo ukuze sihlole, bese sihlaziya idatha yokuhlola.I-sphere evamile yokuhlanganisa inganikeza amapharamitha ayisithupha abalulekile alandelayo: ukuguquguquka okukhanyayo, ukusebenza kahle okukhanyayo, i-voltage, ukudidiyelwa kombala, izinga lokushisa lombala, kanye...Funda kabanzi -
Ukuthuthukiswa kokukhanyisa okuhlakaniphile kwezimboni kanye nezicelo
Izitimela, ichweba, isikhumulo sezindiza, umzila wesitimela, ezokuvikela kuzwelonke, kanye neminye imikhakha esekelayo ikhuphuke ngokushesha eminyakeni yamuva nje ngokumelene nesizinda sengqalasizinda yasekhaya kanye nokufudukela emadolobheni, okuhlinzeka ngamathuba okukhula okuthuthukiswa kwebhizinisi lokukhanyisa izimboni.Inkathi entsha yezimboni...Funda kabanzi -
Ukuhlaziywa kwemizila yobuchwepheshe eyinhloko ye-LED emhlophe yokukhanyisa
1. I-blue LED chip+yellow green phosphor, okuhlanganisa okuphuma ku-polychrome phosphor Ungqimba oluphuzi lwephosphor lumunca ukukhanya okuluhlaza okwesibhakabhaka kwamanye ama-chips e-LED ukuze kukhiqizwe i-photoluminescence, futhi ukukhanya okuluhlaza okwesibhakabhaka okuvela kuma-chips e-LED kukhiphela ngaphandle kwesendlalelo se-phosphor futhi kuhlangane nokuphuzi. i-green lig...Funda kabanzi -
Izimfihlo eziyisishiyagalolunye zamandla okushayela amalambu e-LED ekhwalithi ephezulu
Ukuthuthukiswa kokukhanyisa kwe-LED kungene esigabeni esisha.Ugesi wekhwalithi ephezulu oshayela isibani se-LED wokukhanyisa kwesimanje unezidingo ezilandelayo: (1) Ukusebenza kahle okuphezulu nokushisa okuncane Ngenxa yokuthi ugesi uvamise ukwakhelwa ngaphakathi, kanye nobuhlalu bebulb ye-LED, ukushisa okukhiqizwa ...Funda kabanzi -
Kungani kulula ukugqashuka izibani eziholayo ehlobo?
Angazi noma uthole ukuthi noma ama-led bulbs, ama-ceiling lights, amalambu e-led table, ama-projection lights, amalambu aholayo ezimbonini nasezimayini, njll., kulula ukuphuka ehlobo, kanye namathuba okuba ukubhidliza kuphakeme kakhulu kunalokho kwasebusika.Kungani?Impendulo ithi...Funda kabanzi -
Izindawo ezishisayo eziyishumi zokuthuthukiswa kobuchwepheshe bohlelo lokusebenza lwe-LED
Okokuqala, ukusebenza kahle kwamandla okuphelele kwemithombo yokukhanya ye-LED nezibani.Ingqikithi yamandla okusebenza kahle = ukusebenza kahle kwe-quantum yangaphakathi × Ukusebenza kahle kokukhishwa kokukhanya kwe-Chip × Ukusebenza kahle kokukhishwa kokukhanya kwephakheji × Ukuphumelela okujabulisayo kwe-phosphor × Ukusebenza kahle kwamandla × Ukusebenza kahle kwesibani.Okwamanje, leli nani lingaphansi kwe-th...Funda kabanzi -
