Umahluko phakathi koMthombo wokukhanya oDityanisiweyo we-LED

Umthombo wokukhanya wesibane sesibane se-LED esisebenzayo, i-LED edibeneyo yomthombo wokukhanya wokukhanya komhlaba umonakalo okanye ukuqhekeka kubangela ukuba umthombo wokukhanya ungakwazi ukukhanyisa kwaye isibane esifileyo sibi. I-W, ngaphezu kwe-70LM/W kunye ne-100LM/W yezibane ze-T5 ezinezibane eziqhelekileyo ze-fluorescent, okwenza umphumo wokukhanya ngokubanzi weebhokisi zokukhanya ze-LED phezulu. Isiphumo sokukhanya esidlulayo se-LED sibhekisa ekusebenzeni kokukhanya komthombo wokukhanya we-LED xa uqalisa ukusebenza, okwaziwa ngokuba yimpembelelo yokukhanya yelizwe elibandayo. Kukuguquguquka okubonakalayo okukhawulezileyo okulinganiswa yi-pulse emfutshane ethile ngoku ngumthombo wokulinganisa. Ixesha lokufudumeza rhoqo le-substrate, ububanzi be-pulse yokufudumala ngokuqhelekileyo i-1- yamashumi e-ms. Imithombo yokukhanya edibeneyo yokukhanya kwe-LED okanye imithombo yokukhanya ebangelwa i-welding okanye ukusetyenziswa, intambo yegolide iyaphulwa ngexesha lokwandiswa kwe-thermal kunye nokunciphisa i-colloid, ebangela izibane ezifileyo; Ukongeza, umthombo wokukhanya we-LED ngumthombo wokukhanya oqinileyo. Oku kuthetha ukuzinza ngakumbi. Ukongezelela, ubomi benkonzo yezibane eziphezulu ze-sodium kunye nezibane ze-halide zegolide zihlala zingaphantsi kweeyure ze-6000, kwaye isalathisi sombala singaphantsi kwama-30; I-LED ineenzuzo ezibalulekileyo ezifana nokusebenza okuphezulu, ukonga amandla, ubomi obude (iiyure ezingama-50,000), ukukhuselwa kwendalo, isalathiso sombala ophezulu ( > 75), njl. Indlela yokusebenzisa ngokufanelekileyo ii-LED ekukhanyeni kwendlela ibe yinto ethandwa kakhulu kwi-LED kunye nabavelisi bokukhanya kwesitrato. Njengoko ingundoqo yezibane zesitrato ze-LED, iteknoloji yokuvelisa i-chips ze-LED kunye ne-teknoloji yokupakisha ehambelanayo ngokudibeneyo inquma amathuba okusebenza kwe-LED kwintsimi yokukhanyisa kwixesha elizayo. Esona sizathu siphambili sokungaphumeleli okukhulu kukutyheli okanye ukuncitshiswa kwe-silicone okanye ukunciphisa. I-LED P kunye ne-N electrode esemthethweni ikwicala elifanayo le-LED. Umjelo kufuneka uhambe ngaphaya kwe-N-GAN umaleko ngokuthe tye, okukhokelela kumbane ogcweleyo, ubushushu obuphezulu bendawo, kunye nokunciphisa umsinga wokuqhuba. Inyamalala. Kwinkqubo yokusetyenziswa kwexesha elide, ubushushu obuphezulu obubangelwa ukutshatyalaliswa kobushushu buchaphazela ukusebenza kunye nokuhanjiswa kwe-silicone, okubangela ukukhutshwa kwamandla okukhanya okukhulu. Umthombo wokukhanya odibeneyo we-LED awunayo kuphela isantya sokuqalisa ngokukhawuleza, kodwa unama-engile amaninzi xa uyisebenzisa. Akukho xinzelelo kwintelekelelo, emacaleni, nakwingqikelelo ejiyileyo. Ngenxa yenkqubo yenkqubo enzima, inkqubo yenkqubo ayikwazi ukulungiswa. Inkqubo yesicelo senkqubo eguqulweyo ilula, kwaye ukukhanya okubi kunokulungiswa. Xa kuthelekiswa nenkqubo yokupakisha ngokusesikweni, ukuxinana kokupakisha kwenkqubo eguquliweyo kuye kwanda ngamaxesha e-16. Ukupakishwa okudityanisiweyo kukwabizwa ngokuba yipolycrystalline packaging. Inani lee-chips ze-LED kwisiseko se-substrate esekelwe kumandla afunekayo anqunywe. I-3W ephezulu -ukukhanya okuphezulu kwezixhobo ze-LED zamandla. Ekugqibeleni, i-chip ifakwe kwi-chip kunye ne-high refractive index material ngokwemilo ye-optical design. Umqulu weCob “Imodyuli yokukhanya yokukhanya kwe-COB →Izibane ze LED ”, Inokuthi ifakwe ngokuthe ngqo ngee-chips ezininzi kwi-MCPCB kwibhodi yesekethe yoshicilelo yesinyithi, kwaye ikhuphe ngokuthe ngqo ubushushu ngokusebenzisa i-substrate yokugcina iindleko zokupakisha ze-LED, iindleko zokuvelisa imodyuli yokukhanya, kunye neendleko zokukhanyisa okwesibini. Ngokubhekiselele ekusebenzeni, ngokuyila okufanelekileyo kunye ne-microscope, imodyuli yomthombo wokukhanya we-COB inokuphepha ngokufanelekileyo ukungalungi kokukhanya kunye ne-glare ekhoyo ekudibaneni kokwahlula izixhobo zomthombo wokukhanya; inokuphucula ngokufanelekileyo umbala womthombo wokukhanya ngokongeza indibaniselwano efanelekileyo yetshiphu ebomvu ngokwesondo. Umthombo wokukhanya ohlanganisiweyo we-LED umthamo wokupakishwa uncitshiswe nge-80%, ukukhanya kombala wokuhanjiswa kufana kakhulu, kwaye iindleko ziphantsi, kodwa iitshiphusi ezincinci zibopheleleke ukuba zibeke phambili iimfuno zobugcisa eziphezulu kakhulu zokuchaneka kwezixhobo kunye nokuncamathisela okuqinileyo kwecrystal tinnodium.
