Namhlanje, ndingathanda ukwabelana nawe ngempembelelo yezibane ze-LED kwi-heat dissipation yezibane. Iingongoma eziphambili zezi zilandelayo:
I-1, Eyona mpembelelo ngqo-imbi yokutshatyalaliswa kobushushu ikhokelela ngokuthe ngqo ekunciphiseni ubomi benkonzo yezibane ze-LED
Ekubeni izibane ze-LED ziguqula amandla ombane ekukhanyeni okubonakalayo, kukho ingxaki yokuguqulwa, engakwazi ukuguqula i-100% yamandla ombane kumandla okukhanya. Ngokomthetho wogcino lwamandla, amandla ombane agqithileyo aguqulwa abe ngamandla obushushu. Ukuba uyilo lwesakhiwo sokutshatyalaliswa kobushushu bezibane ze-LED alunangqiqo, le nxalenye yamandla okushisa ayinakupheliswa ngokukhawuleza. Emva koko ngenxa yobungakanani obuncinci bokupakishwa kwe-LED, izibane ze-LED ziya kuqokelela amandla amaninzi obushushu, okukhokelela kubomi obuncitshisiweyo.
2, kubangela ukwehla komgangatho wezinto
Ngokuqhelekileyo izixhobo ze-elektroniki ezisetyenziselwa ixesha elide, inxalenye yempahla iya kuba lula i-oxidize. Njengoko ukushisa kwezibane ze-LED kuphakama, ezi zinto zixutywa ngokuphindaphindiweyo kwi-oxidized kwiqondo lokushisa eliphezulu, eliya kubangela ukuhla komgangatho, kwaye ubomi bufutshane. Ngelo xesha, ngenxa yokutshintsha, isibane sabangela ukwanda kwe-thermal kunye nokunyuka okubandayo, ukwenzela ukuba amandla ezinto eziphathekayo atshatyalaliswe.
I-3, ukushisa okugqithisileyo kubangela ukusilela kwezixhobo zombane
Le yingxaki eqhelekileyo yomthombo wobushushu be-semiconductor, xa ubushushu be-LED bukhuphuka, ukunyanzeliswa kombane kuyanda, okukhokelela ekwandeni kwangoku, ukonyuka kwangoku kukhokelela ekunyukeni kobushushu, ngoko ke umjikelo obuyiselayo, ubushushu obuninzi buya kubangelwa, ekugqibeleni kuya kubangela i-elektroniki. amacandelo overheating kunye nomonakalo, ebangela ukusilela elektroniki.
4. Izinto zezibane kunye nezibane zikhubazekile ngenxa yokushisa okukhulu
Izibane ze-LED zenziwe ngamacandelo amaninzi, iindawo ezahlukeneyo ezenziwe ngezinto ezahlukeneyo. Ubungakanani bezi zixhobo buhluke kukwandiswa kwe-thermal kunye nokunciphisa okubandayo. Xa iqondo lokushisa liphakama, ezinye izinto ziya kwanda kwaye zigobe ngenxa yokushisa okukhulu. Ukuba indawo phakathi kweendawo ezikufutshane zincinci kakhulu, ezi zimbini zinokucinezela, ezinokulimaza iindawo kwiimeko ezinzulu.
Ukutshatyalaliswa kokushisa okungahambi kakuhle kwezibane ze-LED kuya kuvelisa iingxaki ezininzi. Iingxaki zala macandelo ziya kubangela ukuhla kokusebenza kwazo zonke izibane ze-LED kunye nokunciphisa ubomi babo. Ngoko ke, iteknoloji yokutshatyalaliswa kobushushu be-LED yingxaki ebalulekileyo yezobugcisa. Kwixesha elizayo, ngelixa liphucula izinga lokuguqulwa kwamandla e-LED, isakhiwo sokutshatyalaliswa kobushushu be-LED kufuneka siyilwe ngokufanelekileyo, ukwenzela ukuba izibane zokukhanyisa i-LED zikwazi ukulahla inkathazo yokutshatyalaliswa kobushushu.
