Zigawo za magetsi a LED: semiconductor material chip, guluu woyera, bolodi wozungulira, epoxy resin, core waya, chipolopolo.Nyali ya LED ndi electroluminescent semiconductor material chip, yomwe imachiritsidwa pa bulaketi ndi guluu wasiliva kapena guluu woyera, ndiyeno imagwirizanitsa chip ndi bolodi lozungulira ndi waya wasiliva kapena waya wagolide.Malo ozungulira amasindikizidwa ndi epoxy resin kuteteza waya wamkati wamkati.Ntchito, potsiriza ikani chipolopolocho, kotero nyali ya LED imakhala ndi ntchito yabwino ya seismic.

Diode yotulutsa kuwala kwa LED ndi chipangizo cholimba cha semiconductor chomwe chimatha kusintha mphamvu yamagetsi kukhala kuwala kowonekera.Ikhoza kutembenuza mwachindunji magetsi kukhala kuwala.Mtima wa LED ndi chipangizo cha semiconductor, mapeto amodzi a chip amamangiriridwa ku chithandizo, mapeto amodzi ndi pulasitiki yoipa, ndipo mapeto ena amagwirizanitsidwa ndi mtengo wabwino wa magetsi, kotero kuti chip chonsecho chimatsekedwa. ndi epoxy resin.

Mfundo yotulutsa kuwala kwa magetsi a LED

Pamene panopa akudutsa mu mtanda wopyapyala, ma elekitironi mu N-mtundu semiconductor ndi mabowo mu P-mtundu semiconductor mwamphamvu kugundana ndi recombin mu kuwala-emitting wosanjikiza kupanga photons, amene amatulutsa mphamvu mu mawonekedwe a photons (ndiko kuti. , kuwala kumene aliyense amawona).Ma semiconductors azinthu zosiyanasiyana adzatulutsa mitundu yosiyanasiyana ya kuwala, monga kuwala kofiira, kuwala kobiriwira, kuwala kwa buluu ndi zina zotero.

Pakati pa zigawo ziwiri za semiconductors, ma elekitironi ndi mabowo amawombana ndikuphatikizana ndikupanga mafotoni abuluu munsanjika yotulutsa kuwala.Mbali ya kuwala kwa buluu yopangidwa idzatulutsidwa mwachindunji kudzera mu zokutira za fulorosenti;gawo lotsala lidzagunda chophimba cha fulorosenti ndikulumikizana nacho kuti apange mafotoni achikasu.Photon ya buluu ndi photon yachikasu imagwira ntchito pamodzi (yosakanikirana) kuti ipange kuwala koyera
