I-AustarIzibane zesitalato ze-LEDeveliswa zizibane ze-Led street Abavelisi ukuba babe neenzuzo ezininzi kuneemveliso zemveli. Izibane zesitalato ze-LED zinobomi obude kunye nokusebenza okuphezulu ngokuguqula amandla abe ukukhanya ukunqumla ubushushu kangangoko kunokwenzeka.
Nangona kunjalo, izibane ezikhanyisayo ziya kuvelisa ukushisa okungenakuphepheka, okuya kuchaphazela kakubi izibane zesitrato zaseTshayina, kuquka ukuphelisa ubomi, ukulimaza imiphumo yokukhanyisa, kunye nokunciphisa i-CRI. Ngoko ke, yinxalenye ephambili yokunqumla ubushushu. Ukukhanya okuphezulu kobume obuqinileyo (SSL) uncedo.
Enyanisweni, kwizibane ze-LED zesitalato, ukushisa okusebenzayo kuxhalabele kakhulu. Okukhona iqondo lobushushu liphezulu, kokukhona ubomi bufutshane. Ubushushu be-LED obuqhelekileyo abunandisi nje ubomi kuphela kodwa bubonelela ngokukhanya ngakumbi. Kukho iindlela ezininzi kunye neendlela zokuphucula ulawulo lwe-thermal ye-LED, kubandakanywa iindlela zombini zokubethelela izinto ze-resin kunye nezixhobo zokujonga i-thermal conductive.
Isixhobo sojongano lwe-thermal conductive siyilwe njengesibophelelo phakathi kwecandelo kunye ne-heat sink ukukhawulezisa ilahleko yobushushu ukuthoba ubushushu bokusebenza. Kwakhona, izinto eziphilisiweyo zisetyenziselwa i-adhesive egubungela i-RTV okanye i-epoxy resin material, ekhethwe ngokwamandla okubambelela kunye nobushushu bokusebenza.
Enye inketho yinto ye-thermal conductive encapsulating resin enika ukhuseleko oluyimfuneko kunye ne-heat sink yesixhobo. Izinto ze-resin ezifakwe kwi-encapsulated zifumaneka ngokubanzi, kubandakanywa i-epoxy resins, i-polyurethane resins, kunye ne-silicone resins.
Iinreyi zePolyurethane zinokuguquguquka okuhle, ngakumbi kumaqondo obushushu aphantsi, njengenzuzo enkulu ngaphezulu kwe-epoxy resins. Kwakhona, i-silicone resins inomsebenzi ofanayo, kodwa ngexabiso eliphezulu. Ngokuphathelele i-epoxy resin, yimveliso enqabileyo enika ukhuseleko olugqwesileyo kwiindawo ezinoburharha nezirhabaxa. Izinto ezifakwe kwi-resin zinceda ukuyila izibane ezininzi ze-LED ngokweemfuno zabathengi.
Ngophuhliso olukhawulezayo lweshishini lombane, ukucaciswa kwezicelo ze-LED, izixhobo zokupholisa kufuneka ziphuculwe ngokufanelekileyo, zenze igalelo elikhulu ekuphuculeni nasekuphuhliseni izibane zesitalato zaseTshayina.
