Alumina Ceramic Part of Lighting System
Daim ntawv thov teb
Alumina ceramics yog dav siv nyob rau hauv lub teeb pom kev zoo nrog cov cuab yeej siv siab, siab hardness, ntev hnav, rwb thaiv tsev loj, tiv thaiv corrosion zoo, kub resistant.
Alumina ceramics qhov chaw tuaj yeem siv rau hauv cov teeb thiab teeb.Lub thermal conductivity ntawm alumina ceramic substrates ranges ntawm 29. 3W / (m · K) txog 35W / (m · K), uas yog kwv yees li kaum mus rau nees nkaum npaug ntawm aluminium substrates.Thaum siv rau LEDs, lawv tuaj yeem ua kom sov thiab ua kom lub neej ntev tshaj plaws ntawm LED.Yog tias nruab nrog lub tshav kub dissipation radiator zoo, yuav tsis muaj qhov sib txuas ntawm qhov kub thiab txias, uas tuaj yeem muab kev tiv thaiv siab tshaj plaws rau lub teeb hlaws .Tuam Tshoj yog lub lag luam loj tshaj plaws ntawm alumina ceramics qhov chaw.feem ntau ntawm alumina ceramic yog exported.
Paub meej
