(Gawo la CeramicZopangidwa ndiWintrusetk)
Ma LED ndi zida za electroluminescent semiconductor zomwe zimatembenuza pafupifupi 70% mpaka 80% ya mphamvu zawo zomwe zimaperekedwa kukhala kutentha. Ngati kutenthaku sikungathe kutsanulidwa bwino pagawo laling'ono, kuwonjezeka kwa kutentha kwa mphambano kumapangitsa kuchepa kwa mphamvu ya mkati, kuwonongeka kwa phosphor, ndi kufulumizitsa moyo wa chipangizocho.
matabwa Traditional zitsulo-pachimake kusindikizidwa dera matabwa (MCPCBs) ndi mkulu matenthedwe kukana chifukwa chofunika polima kutchinjiriza wosanjikiza pakati pa zitsulo ndi zigawo zigawo, kuwapangitsa iwo mochulukira kulephera kukwaniritsa kutentha dissipation zosowa za mkulu-mphamvu ndi kopitilira muyeso-mkulu-mphamvu LEDs. Mosiyana,magawo a ceramickuphatikiza kutchinjiriza ndi matenthedwe matenthedwe, kuchotsa interfacial kukana kutentha ndi kukhala chizolowezi chosalephereka pa kusintha kwa makampani.
1. Alumina (Al2O3)
Alumina ceramic ndiye chinthu chokhazikika komanso chogwiritsidwa ntchito kwambiri. Imawonetsa kusinthasintha kwa kutentha kwa 25-30 W / m.K, mphamvu zamakina abwino, komanso mawonekedwe abwino a dielectric.
Ubwino:
Mapulogalamu: Amagwiritsidwa ntchito kwambiri pakuwunikira wamba, kuwunikira kwamagetsi kwa ogula, ndi ma module apakatikati amphamvu.
2. Aluminiyamu Nitride (AlN)
Kwa COB yamphamvu kwambiri komanso kuyatsa kwa laser yama automotive-grade, AlN ndi yodziwika bwino chifukwa cha kutenthetsa kwake kwamphamvu kwambiri.
Ubwino:
Kutentha kwa matenthedwe kumafika 170-230 W/m.K, pafupifupi kasanu ndi katatu kuposa alumina.
Kukula kwamafuta kumayenderana kwambiri ndi zida za semiconductor monga silicon ndi silicon carbide, kumathandizira kwambiri kukhazikika kwamakina a zida m'malo oyendetsa njinga otentha.
Mapulogalamu: Nyali zamagalimoto, mapurojekitala amphamvu kwambiri m'mafakitale, ndi zida zakuya za UVC zoyeretsera ma ultraviolet.
3. Silicon Nitride (Si3N4)
Silicon nitride imayang'anira zovuta zaukadaulo za kuwonongeka kwachilengedwe kwa zoumba zachikhalidwe, zomwe zimakhala ndi kulimba kwapang'onopang'ono komanso kulimba kwamphamvu.
Ubwino:
Mapulogalamu: Kuunikira kwamagulu ankhondo, zida za optoelectronic zamlengalenga, ndi ma module a LED amakampani omwe amafunikira kudalirika kwambiri.
