Ngokufutshane malunga nendlela yokuphelisa ubushushu besibane sesikhukula se-LED

Ekukhanyeni kwangaphandle kwezibane zezikhukhula, Izibane zoKhuseleko lwaseKhaya zidlala indima ebalulekileyo.Ezinye iziganeko ezikhethekileyo, ezifana nokukhanyiswa kwezikwere, iindlela zokuhlangana, iindawo ezithile, njl., ngenxa yobungcali bazo, okanye iiMfuno zokukhanyisa, ngamanye amaxesha ukukhanya okunamandla aphezulu kuyafuneka.Kwixesha elidlulileyo, iiprojekthi ezininzi zokukhanyisa zisebenzisa izibane eziphezulu ze-sodium ezinoxinzelelo oluphezulu kunye nesakhiwo seentloko zesibane ezininzi ukuhlangabezana neemfuno zokukhanyisa.

Umgangatho we-radiator yesibane ngumba ophambili ochaphazela ngokuthe ngqo ubungakanani bokubola kokukhanya.Iindlela ezintathu ezisisiseko zobuchwepheshe bokutshatyalaliswa kobushushu kunye nokutshintshwa kobushushu bezindlu zesibane zezi: ukuqhuba, ukuqhutyelwa kunye nemitha.Ulawulo lwe-thermal nalo luqala kule miba mithathu, eyahlulahlulwe kuhlalutyo lwexeshana.Kwaye uhlalutyo oluzinzileyo.Indlela ephambili yokuhambisa i-radiator yi-conduction kunye ne-convection heat dissipation, kunye nokutshatyalaliswa kokushisa okukhanyayo phantsi kwe-convection yendalo ayikwazi ukunyanzeliswa.Izibane zokukhanyisa zisebenzisa amandla amakhulu e-LEDs.

Briefly on how to dissipate the heat of LED flood light

Okwangoku, ukukhanya okukhanyayo kwee-LED eziphezulu zorhwebo kuphela kwi-15% ukuya kwi-30%, kwaye uninzi lwamandla aseleyo aguqulwa abe ngamandla obushushu.Ukuba amandla okushisa akakwazi ukukhutshwa ngokufanelekileyo, kuya kukhokelela kwimiphumo emibi.Ubushushu obuphezulu buya kunciphisa ukuguquguquka okukhanyayo kunye nokusebenza kakuhle kwe-LED, kubangele ukukhanya okubomvu kwamaza, ukuphoswa kombala, kwaye kubangele izinto ezimbi ezinje ngokuguga kwesixhobo.Into ebaluleke kakhulu kukuba ubomi be-LED buya kuncitshiswa ngokukhawuleza, ngenxa yokubola kokukhanya kwe-LED okanye ubomi bayo.Ihambelana ngokuthe ngqo nobushushu bayo bokuhlangana.Ukuba ukutshatyalaliswa kobushushu akulunganga, ubushushu be-junction buya kuba phezulu kwaye ubomi buya kuba bufutshane.Ngokomthetho ka-Arrhenius, ubomi buya kwandiswa ngamaxesha angama-2 kwi-10 ° C yokuncipha kweqondo lokushisa.
