Uyini Umehluko Phakathi Kwamandla E-LED Aphezulu Namandla Amancane?

Amandla awodwa okukhanya kwe-LED okunamandla aphezulu aphezulu, ukukhanya kugqamile, futhi intengo iphakeme. Isilinganiso samanje samandla amancane amalambu e-LED singu-20mA, futhi esamanje esilinganiselwe singabalwa njengamandla aphezulu anesilinganiso samanje esingaphezu kuka-20mA. Inombolo yamandla evamile ithi: 0.25W, 0.5W, 1W, 3W, 5W, 8W, 10W, njll. Iyunithi yokukhanya eyinhloko yi-LM (lumen), futhi iyunithi yokukhanya yamandla amancane ngokuvamile i-MCD. Lawa mayunithi amabili awakwazi ukuguqulwa. Njengamanje, njengohlaza olusafufusa, ukuvikelwa kwemvelo, umthombo wokukhanya osindisa amandla usetshenziswa kabanzi ezibani zemoto, amathoshi, izibani nezinye izindawo. Isizathu sokuthi kungani izibani ze-LED ezinamandla amakhulu zibizwa ngokuthi lokhu ikakhulukazi amalambu e-LED anamandla amancane. Kunezinhlobo ezintathu zamazinga okuhlukanisa: eyokuqala izohlukaniswa ibe ngu-0.5W, 1W, 3W, 5W, 10W. I-.100W ihlukile, ngokuya ngamandla aphelele omkhiqizo wokubumba ngemva kokupakishwa. Uhlobo lwesibili lungahlukaniswa lube: ukupakishwa kwe-epoxy resin enkulu, ukulingisa ukupakishwa kwe-mermaid epoxy resin, ukupakishwa kwe-aluminium, i-aluminium, i-aluminium, ne-aluminium. Uhlobo lwesithathu lwe-substrate (MCPCB) encapsulation, Ukupakisha, iphakheji ye-SMD yohlobo lwamandla, iphakheji ehlanganisiwe ye-MCPCB, njll. Uhlobo lwesithathu lungahlukaniswa lube yimikhiqizo yamandla eguga ekhanyayo ephansi kanye nemikhiqizo yamandla eguga angewona -low-light ngokuya ngezinga layo lokuguga okukhanyayo. Yiqiniso, ngenxa yokuthi kunemingcele eminingi yokukhanya kwe-LED enamandla aphezulu ngokwayo, kuzoba nezindinganiso ezihlukene zokuhlukanisa ngokuvumelana nemingcele ehlukene. Izibani ze-LED ezinamandla aphezulu zisengawomunye wemikhiqizo yokupakisha ye-LED, okuyingxenye ebaluleke kakhulu yokukhanyisa kwe-semiconductor ebheke emkhakheni wokukhanyisa okuvamile. Uma usebenzisa izibani ze-LED ezinamandla amakhulu, kufanele uqonde ukusatshalaliswa kokukhanya kokusabalalisa ukukhanya, ukusatshalaliswa kwezinga lokushisa lombala, ukumelana nokushisa nokukhishwa kombala ukuze ube yingcweti yemephu yokusabalalisa yokukhanya kokukhanya kwe-W -class high -power LED light. Kuyadingeka ukusebenzisa kahle ukukhanya kwe-LED okunamandla aphezulu. Abakhiqizi kumele banikeze amakhasimende izinkomba ezihlukahlukene zepharamitha zamadivayisi we-LED noma ngabe ukusatshalaliswa kokushisa kombala kwezibani ze-LED zamandla aphezulu kusatshalaliswa ngokulinganayo, okuzothinta ngqo umphumela wokukhanyisa; futhi izinga lokushisa lombala nenkomba yokunikeza umbala kuxhumene, futhi ukushintsha kwezinga lokushisa lombala kuzobangela izinguquko kunkomba yokunikeza umbala. Ukumelana okushisayo kokukhanya kwe-LED okunamandla amakhulu kuthinta ngokuqondile ukuchithwa kokushisa kwamadivayisi we-LED. Ukumelana nokushisa okuphansi, kungcono ukuchithwa kokushisa; ukumelana nokushisa kubi, ukuze izinga lokushisa ledivayisi likhuphuke, okuzothinta ukukhukhuleka kwe-wavelength kokukhanya. Ngokusho kokuhlangenwe nakho, izinga lokushisa liyakhuphuka kanye, futhi ubude begagasi lokukhanya kufanele bukhukhuleke ngo-0.2 0.3nm, okuzothinta ngokuqondile ikhwalithi ekhanyayo yedivayisi. Ukwenyuka kwezinga lokushisa okweqile nakho kuthinta ngqo impilo yesevisi ye-W -level high -power LED isibani sokulondoloza amandla. Umbala uyinkomba ebalulekile yokukhanya okumhlophe kwe-LED. Umbala wokukhanya okumhlophe kwe-LED yokukhanyisa kumele ube ngaphezu kwama-80 noma ngaphezulu.
