Ngokuthuthuka okusheshayo kokukhanyisa kwe-LED namuhla, ukuchithwa kokushisa kuyinkinga eyinhloko yokukhanyisa kwe-LED.Singayixazulula kanjani inkinga yokukhishwa kokushisa kwe-LED?Namuhla sizokhuluma ngenkinga ye-LED ye-heat dissipation yethusi substrate ye-LED yokushisa ukushisa.
Imboni ye-LED ingenye yezimboni ezidonse ukunaka okukhulu eminyakeni yamuva.Kuze kube manje, imikhiqizo ye-LED inezinzuzo zokonga amandla, ukonga amandla, ukusebenza kahle okuphezulu, isikhathi sokuphendula esisheshayo, umjikelezo wempilo ende, i-mercury-free, kanye nezinzuzo zokuvikelwa kwemvelo.Kodwa-ke, ngokuvamile cishe u-15% wamandla okufakwayo wemikhiqizo ye-LED enamandla amakhulu angaguqulwa abe ukukhanya, futhi u-85% osele wamandla kagesi uguqulwa ube amandla okushisa.
Ngokuvamile, uma amandla okushisa akhiqizwa ukukhanya kwe-LED engakwazi ukuthunyelwa ngaphandle, izinga lokushisa le-junction ye-LED lizoba phezulu kakhulu, elizothinta umjikelezo wempilo yomkhiqizo, ukusebenza kahle okukhanyayo, nokuzinza.Ubudlelwano phakathi kwezinga lokushisa le-junction ye-LED, ukusebenza kahle okukhanyayo, nobudlelwano bempilo.
Emklamo wokukhipha ukushisa kwe-LED, into ebaluleke kakhulu ukunciphisa ngokuphumelelayo ukumelana nokushisa kusuka kungqimba olukhipha ukukhanya lwe-chip kuya emvelweni.Ngakho-ke, kudingekile kakhulu ukukhetha i-substrate efanelekile yokushisa ukushisa kanye nezinto ezibonakalayo.
I-substrate yethusi ekhipha ukushisa ithwala ukushisa kwama-LED namadivayisi.Ukushisa kokushisa ikakhulukazi kuncike endaweni, futhi i-substrate yethusi ene-conductivity ephezulu yokushisa ingakhethwa ekuqhubeni ukushisa okugxilile.
