(Keramic SubstrateE hlahisoa keWintrusetk)
Li-LED ke lisebelisoa tsa semiconductor tsa electroluminescent tse fetolang hoo e ka bang 70% ho isa ho 80% ea matla a tsona a fanoeng mocheso. Haeba mocheso ona o ke ke oa ntšoa hantle ka substrate, ho eketseha ha mocheso oa mateano ho tla fella ka ho theoha ha katleho ea ka hare ea quantum, phosphor degradation, le ho potlakisa nako ea bophelo ba sesebelisoa.
Liboto tsa setso tse hatisitsoeng tsa tšepe-core (MCPCBs) li na le khanyetso e phahameng ea mocheso ka lebaka la lera le hlokahalang la polymer pakeng tsa tšepe le likarolo tsa potoloho, e leng se etsang hore li se ke tsa khona ho kopana le litlhoko tsa ho felloa ke mocheso tsa matla a phahameng a matla le li-ultra-high-power. Ho fapana le hoo,li-substrates tsa ceramickopanya ho kenya letsoho le ho tsamaisa mocheso, ho felisa ho hanyetsa mocheso oa sefahleho le ho fetoha mokhoa o ke keng oa qojoa oa ho iphetola ha indasteri.
1. Alumina (Al2O3)
Alumina ceramic ha joale ke thepa ea substrate e tsebahalang haholo le e sebelisoang hangata. E bonts'a conductivity e tsitsitseng ea mocheso oa 25-30 W / m.K, matla a matle a mochine, le litšobotsi tse ntle tsa dielectric.
Melemo:
Theknoloji e hōlileng tsebong
Matla a phahameng a mochine
Insulation e ntle haholo
Litsenyehelo tse phahameng tsa tlhōlisano
Lisebelisoa: E sebelisoa haholo ho khantša ka kakaretso, lisebelisoa tsa motlakase tsa bareki, le li-module tsa ho paka tsa matla a mahareng.
2. Aluminium Nitride (AlN)
Bakeng sa COB ea matla a holimo le mabone a laser a automotive-grade, AlN e hlahella ka lebaka la ho sebetsa ha eona ho phahameng haholo.
Melemo:
Thermal conductivity fihla ho 170-230 W/m.K, hoo e ka bang makhetlo a robeli a alumina
Coefficient ea katoloso ea mocheso e lumellana haholo le lisebelisoa tsa semiconductor tse kang silicon le silicon carbide, e ntlafatsang haholo botsitso ba mochini oa lisebelisoa libakeng tsa libaesekele tse futhumetseng.
Lisebelisoa: Mabone a likoloi, liprojeke tsa motlakase tse phahameng tsa indasteri, le lisebelisoa tse tebileng tsa UVC tsa tlhoekiso ea ultraviolet.
3. Silicon Nitride (Si3N4)
Silicon nitride e sebetsana le phephetso ea tekheniki ea bofokoli ba tlhaho ba lirafshoa tsa setso, tse nang le bothata bo phahameng haholo ba ho robeha le matla a feto-fetohang.
Melemo:
Lisebelisoa: Mabone a boemo ba sesole, lisebelisoa tsa optoelectronic tsa sefofane, le li-module tsa LED tsa boemo ba indasteri tse hlokang ts'epahalo e phahameng haholo.
