Izibane zendlela ze-LEDngoku zisetyenziswa ngokubanzi, kwaye iindlela ezininzi nangakumbi zikhuthaza ukusetyenziswa kwezibane zesitrato ukuze zithabathele indawo incandescent yemveli kunye nezibane zesodium ezinoxinzelelo oluphezulu. Nangona kunjalo, amaqondo okushisa ehlobo ayanda ngamandla minyaka yonke, kwaye izibane zesitrato zihlala zijongene nomngeni wokutshatyalaliswa kobushushu. Kwenzeka ntoni ukuba umthombo wesibane sesitrato awubuchitheli ngokufanelekileyo ubushushu?
Ukulungiswa kwesibane seTianxiangIbonisa i-conductivity ye-thermal conductivity edibeneyo ehambisa ubushushu obuveliswa ngumthombo wokukhanya kwe-LED ngokuthe ngqo kwi-heat sink, ukunciphisa ukushisa kwangaphakathi. Nakwimozulu eshushu kakhulu ehlotyeni, ukukhanya kwesitrato kugcina ukuqaqamba okulinganiselweyo, kuthintela iingxaki ezinjengokwehla kokukhanya ngequbuliso kunye nokudanyaza okubangelwa ngamaqondo obushushu aphezulu. Oku kufezekisa ngokwenene "uzinzo oluphezulu unyaka wonke" kwaye kubonelela ngokhuseleko oluthembekileyo kwizibane zasezidolophini.
1. Ubomi obufutshane obufutshane
Ukulungiswa kwezibane zesitalato, ukuchithwa kobushushu kubaluleke kakhulu. Ukutshatyalaliswa kobushushu okungalunganga kunokuba neempembelelo ezingalunganga ekusebenzeni kwesibane. Ngokomzekelo, imithombo yokukhanya ye-LED iguqula amandla ombane ekukhanyeni, kodwa ayingawo onke amandla ombane aguqulwa abe ukukhanya ngenxa yomthetho wokulondoloza. Amandla ombane agqithisileyo anokuguqulwa abe bubushushu. Ukuba isibane se-LED sokutshatyalaliswa kobushushu asiyilwanga ngokufanelekileyo, asiyi kukwazi ukutshabalalisa ngokukhawuleza ubushushu obugqithisileyo, okubangela ukufudumala okugqithisileyo kwisibane sesitalato kunye nokunciphisa ubomi baso.
2. Ukwehla komgangatho wezinto eziphathekayo
Ukuba umthombo wesibane sesitalato ugqithisa kwaye awukwazi ukutshabalalisa obu bushushu, izixhobo ziya kuphindaphinda i-oxidize ngenxa yokushisa okuphezulu, okukhokelela ekuthotyweni komgangatho womthombo wokukhanya kwe-LED.
3. Ukungaphumeleli kwecandelo lombane
Njengoko iqondo lokushisa lomthombo wokukhanya kwesitrato liyenyuka ngokuthe ngcembe, ukuchasana okuhlangabezana nako kuyanda, okukhokelela ekugqithiseni kwangoku kwaye, ngenxa yoko, ubushushu obuninzi. Ukushisa ngokugqithiseleyo kunokonakalisa amacandelo e-elektroniki, okukhokelela ekuhlulekeni.
4. Ukuguqulwa kwezinto zesibane
Enyanisweni, sihlala sidibana nale nto kubomi bethu bemihla ngemihla. Umzekelo, xa into ibonakaliswe kubushushu obugqithisileyo, iya konakala kancinci. Kukwanjalo nakwimithombo yokukhanya kwezitalato.
Imithombo yokukhanya ye-LED yenziwe ngezinto ezininzi. Xa iqondo lobushushu liphakama, iindawo ezahlukeneyo ziyakhula kwaye zinciphe ngokwahlukileyo. Oku kunokubangela ukuba amacandelo amabini asondelelane kakhulu, abangele ukuba acinezele omnye komnye, kubangele ukuguquka kunye nomonakalo. Ukuba iinkampani zifuna ukuvelisa izibane ezikumgangatho ophezulu, kufuneka ziqale zibeke phambili uyilo lwesibane sokuphelisa ubushushu. Ukusombulula le ngxaki yokutshatyalaliswa kobushushu kuqinisekisa ubomi obude bokulungiswa kwezibane zesitrato. Ke ngoko, ukuchithwa kobushushu ngumba ophambili ekufuneka izibane ezikumgangatho ophezulu zombane.
Okwangoku, kukho iindlela ezimbini eziphambili zokutshatyalaliswa kobushushu kwizibane zokukhanya ezitalatweni: ukutshatyalaliswa kokushisa okusebenzayo kunye nokutshatyalaliswa kobushushu obusebenzayo.
1. I-Passive heat dissipation: Ubushushu obuveliswa sisibane sesitalato sichithwa ngokuhambisa kwendalo phakathi komphezulu wokukhanya kwesitrato kunye nomoya. Le ndlela yokutshatyalaliswa kobushushu ilula ukuyila kwaye idibanisa ngokulula kunye noyilo lomatshini wokukhanya kwesitrato sokukhanya kwesitrato, ukuhlangabezana lula nenqanaba lokukhusela elifunekayo kwisibane, kwaye lixabiso eliphantsi. Ngoku iyeyona ndlela isetyenziswa kakhulu yokuphelisa ubushushu.
Ubushushu bufuduswa kuqala ngomaleko we-solder ukuya kwisibane se-aluminiyam yesibane sesitrato. Emva koko, i-aluminium substrate ye-thermal conductive adhesive i-adhesive idlulisela kwindlu yesibane. Emva koko, indawo yesibane ihambisa ubushushu kwiintsini ezahlukeneyo zobushushu. Okokugqibela, ukuhanjiswa phakathi kweesinki zobushushu kunye nomoya kususa ubushushu obuveliswa sisibane sesitalato. Le ndlela ilula kwisakhiwo, kodwa ukusebenza kwayo kokutshatyalaliswa kobushushu kuncinci.
2. Ukutshatyalaliswa kobushushu obusebenzayo kuqala kusebenzisa ukupholisa kwamanzi kunye neefeni ukunyusa ukuhamba komoya phezu kwendawo yeradiyetha ukususa ubushushu kwi-heat sink, ukuphucula ukusebenza kakuhle kokutshatyalaliswa kobushushu. Le ndlela inokusebenza kakuhle kokutshabalalisa ubushushu, kodwa ifuna ukusetyenziswa kwamandla okongeziweyo. Le ndlela yokutshatyalaliswa kobushushu inciphisa ukusebenza kwenkqubo yeizibane zesitalatokwaye kunzima kakhulu ukuyila.
