Ngophuhliso olukhawulezayo lokukhanya kwe-LED namhlanje, ukutshatyalaliswa kobushushu kuyingxaki ebalulekileyo yokukhanyisa kwe-LED.Sinokuyicombulula njani ingxaki yokutshatyalaliswa kobushushu be-LED?Namhlanje siza kuthetha ngengxaki ye-LED yokutshatyalaliswa kobushushu be-substrate yobhedu yokutshatyalaliswa kokushisa kwe-LED.
Ishishini le-LED lelinye lamashishini athe atsala umdla kakhulu kwiminyaka yakutshanje.Ukuza kuthi ga ngoku, iimveliso ze-LED zinezibonelelo zokonga amandla, ukonga amandla, ukusebenza kakuhle, ixesha lokuphendula ngokukhawuleza, umjikelo wobomi obude, i-mercury-free, kunye neenzuzo zokusingqongileyo.Nangona kunjalo, ngokuqhelekileyo malunga ne-15% yegalelo lamandla emveliso ye-LED ephezulu inokuguqulwa ibe ukukhanya, kwaye i-85% eseleyo yamandla ombane iguqulwa ibe amandla okushisa.
Ngokuqhelekileyo, ukuba amandla obushushu aveliswa kukukhanya kwe-LED akakwazi ukuthunyelwa ngaphandle, iqondo lokushisa le-junction ye-LED liya kuba liphezulu kakhulu, eliya kuchaphazela umjikelo wobomi bemveliso, ukusebenza kakuhle okukhanyayo, kunye nokuzinza.Ubudlelwane phakathi kobushushu be-junction ye-LED, ukusebenza kakuhle okukhanyayo, kunye nobudlelwane bobomi.
Kuyilo lokutshatyalaliswa kobushushu be-LED, eyona nto ibaluleke kakhulu kukunciphisa ngokufanelekileyo ukuchasana kwe-thermal ukusuka kwi-light-emitting layer ye-chip kwindawo.Ngoko ke, kubaluleke kakhulu ukukhetha i-substrate efanelekileyo yokutshatyalaliswa kobushushu kunye nezinto ezibonakalayo.
I-substrate yobhedu yokutshatyalaliswa kobushushu ithwala ukushisa kwee-LED kunye nezixhobo.Ukutshatyalaliswa kobushushu ikakhulu kuxhomekeke kwindawo, kwaye i-substrate yobhedu ene-conductivity ephezulu ye-thermal inokukhethwa kwi-concentrated conduction conduction.
