1. Ubuchwepheshe bamanje obuqhubekayo be-PWM obunokushisa okuphansi nokunemba okuphezulu okungaguquki kwamanje.Yehlisa ukulahleka kolayini, akukho ukungcoliswa kwegridi yamandla.Isici samandla ngu-0.9, ukuhlanekezela kwe-harmonic kungu-20%, futhi i-EMI ihlangabezana nenkomba yomhlaba wonke, enciphisa ukulahlekelwa kwamandla ezintambo zikagesi futhi igwema ukungcoliswa kokuphazamiseka kwe-high-frequency kugridi yamandla.Inhloko yesibani evamile, ingashintsha ngokuqondile isibani se-halogen esikhona, isibani se-incandescent, isibani se-fluorescent.Ukusebenza kahle kokukhanya okukhanyayo kungaba kufika ku-80 lm/w, izinhlobonhlobo zokushisa kombala okhanyayo we-LED ozikhethela, inkomba enikeza umbala ophezulu, ukunikezwa kombala okuhle.Ngokusobala, inqobo nje uma izindleko zezibani ze-LED zehla ngobuchwepheshe obuholwa.Izibani ezonga amandla nezibani ze-incandescent nakanjani zizoshintshwa ngamalambu e-LED.Isifunda sinaka kakhulu ukonga amandla okukhanyisa kanye nezindaba zokuvikela imvelo, futhi besikhuthaza ngamandla ukusetshenziswa kwezibani ze-LED.
2. Izinga lokwethulwa kombala wento yomthombo wokukhanya libizwa ngokuthi ukusebenza kombala, okungukuthi, izinga lombala wangempela.Umthombo wokukhanya onokusebenza kombala ophezulu unokusebenza okungcono kombala, futhi umbala esiwubonayo useduze nombala wemvelo nokusebenza kombala Imithombo yokukhanya ephansi yenza kubi kakhulu emibaleni, futhi sibona ukuchezuka kwemibala emikhulu.Kungani kungaba khona amaphuzu ocansi aphezulu futhi aphansi?Isihluthulelo sisezicini ze-spectral zokukhanya, ubude be-waveleng bokukhanya okubonakalayo ebangeni le-380nm kuya ku-780nm, esiyibona ku-spectrum yokukhanya okubomvu, okuwolintshi, okuphuzi, okuluhlaza okotshani, okuluhlaza okwesibhakabhaka, okunsomi, uma ukukhanya ukukhanya kuqukethe isilinganiso sokukhanya okumibalabala nokukhanya kwemvelo, umbala wamehlo ethu ungokoqobo.Kodwa abantu abavame ukusebenzisa izibani ze-LED bazothola ukuthi i-LED ngenxa yokukhanya okukhulu ikakhulukazi, kulula ukwenza amandla okukhanya abe amandla okushisa, okwenza izibani ze-LED zishise kakhulu.
Isibani se-fluorescent esingu-3.LED sisebenzisa ubuchwepheshe obusha bomthombo wokukhanya we-LED, idizayini yokubukeka kwedijithali, ukonga amandla angaphezu kuka-70%, amandla okukhanya okukhanyayo okungu-12W kulingana neshubhu le-fluorescent elingu-40W (lokubala kanye nesiqalisi, ukusetshenziswa kwamandla kwangempela kwelambu elingu-36W kungu-42W ukuya ku-44W ).Ukuphila kwesibani se-fluorescent se-LED izikhathi ezingaphezu kwezingu-10 zesibani esivamile, cishe ukugcinwa mahhala, futhi asikho isidingo sokushintsha isibani, i-ballast kanye ne-starter kaningi.I-NASA yesifunda isebenzisa amalambu e-LED esikhaleni, alandelwe ingadi yasekhaya neyokuhweba yasendlini.Umthombo wokukhanya kagesi wesemiconductor eluhlaza, ukukhanya okuthambile, i-spectrum ehlanzekile, kulungele ukuvikelwa kombono nempilo yomsebenzisi.
