LEDs bụ ngwaọrụ semiconductor electroluminescent nke na-agbanwe gburugburu 70% ruo 80% nke ike ha nyere ka ọ bụrụ okpomọkụ. Ọ bụrụ na enweghị ike ịwụpụ okpomọkụ a nke ọma site na mkpụrụ, mmụba nke okpomọkụ nkwụsịtụ ga-eme ka ọ daa n'ime arụmọrụ quantum dị n'ime, mmebi nke phosphor, na ngwa ngwa nke ndụ ngwaọrụ.

Omenala ígwè-isi e biri ebi sekit mbadamba (MCPCBs) nwere elu thermal nguzogide n'ihi chọrọ polymer mkpuchi oyi akwa n'etiti metal na sekit n'ígwé, na-eme ka ha na-esiwanye enweghị ike izute okpomọkụ dissipation mkpa nke elu-ike na ultra-high-power LEDs. N'ụzọ dị iche,seramiiki mkpụrụjikọta mkpuchi na conductivity thermal, na-ewepụ nguzogide ihu igwe na-aghọ ihe a na-apụghị izere ezere na mgbanwe nke ụlọ ọrụ.

1. Alumina (Al2O3)

Alumina seramiiki bụ ihe a na-ejikarị eme ihe ugbu a. Ọ na-egosiputa nrụpụta ọkụ na-agbanwe agbanwe nke 25-30 W / m.K, ike ọrụ dị mma, yana njirimara dielectric mara mma.

Uru:

• Teknụzụ tozuru okè

• Ike igwe dị elu

• Ihe mkpuchi mara mma

• Ọnụ ahịa asọmpi dị ukwuu

Ngwa: A na-eji ya eme ihe na ọkụ n'ozuzu, ọkụ ọkụ ọkụ eletrik nke ndị ahịa, na modul nkwakọ ngwaahịa ọkara.

2. Aluminium nitride (AlN)

Maka COB nwere ike dị elu na ọkụ ọkụ laser ọkwa ụgbọ ala, AlN pụtara n'ihi arụmọrụ ọkụ ya dị oke elu.

Uru:

• Thermal conductivity ruru 170-230 W / m.K, ihe dị ka ugboro asatọ nke alumina.

• Ọnụ ego mgbasawanye nke thermal dakọtara na ihe semiconductor dị ka silicon na silicon carbide, na-eme ka nkwụsi ike nke ngwaọrụ dị na gburugburu ịgba ígwè ọkụ.

Ngwa: Igwe ọkụ ihu ụgbọ ala, ihe nrụpụta ike dị elu nke ụlọ ọrụ mmepụta ihe, yana ngwa nchacha ultraviolet miri UVC.

3. Silicon Nitride (Si3N4)

Silicon nitride na-eleba anya n'ihe ịma aka teknuzu nke nhịkọ siri ike nke seramiki ọdịnala, nwere nnukwu mgbaji siri ike na ike mgbanwe.

Uru:

• eguzogide mmetụta

• na-egbochi ịma jijiji

• Ezi conductivity thermal

Ngwa: Ọkụ ọkụ ọkwa ndị agha, akụrụngwa optoelectronic aerospace, yana modul LED ọkwa ụlọ ọrụ chọrọ ntụkwasị obi dị oke elu.
