Maitiro ekugadzira mabheya emwenje e LED

Maitiro ekugadziraMabhena emwenje e LEDchinhu chakakosha muindasitiri yemwenje ye LED. Mabhedhi e LED, anozivikanwawo se light emitting diodes, zvinhu zvakakosha zvinoshandiswa mumhando dzakasiyana-siyana kubva pamwenje wekugara kusvika kune mhinduro dzemwenje dzemotokari nedzemaindasitiri. Mumakore achangopfuura, nekuda kwezvakanaka zvekuchengetedza simba, hupenyu hurefu, uye kuchengetedzwa kwezvakatipoteredza kwemabhedhi e LED, kudiwa kwawo kwakawedzera zvakanyanya, zvichitungamira mukufambira mberi nekuvandudzwa kwetekinoroji yekugadzira.

Maitiro ekugadzira mabhedhi emwenje e LED anosanganisira matanho akawanda, kubva pakugadzirwa kwezvinhu zve semiconductor kusvika pakusangana kwekupedzisira kwemachipisi e LED. Maitiro acho anotanga nekusarudza zvinhu zvine purity yakawanda zvakaita se gallium, arsenic, uye phosphorus. Zvinhu izvi zvinosanganiswa muhuwandu hwakakodzera kuti zvigadzire makristaro e semiconductor anoumba hwaro hwetekinoroji ye LED.

Mushure mekunge zvinhu zve semiconductor zvagadzirwa, zvinopedza nzira yekuchenesa yakaoma kuti zvibvise tsvina uye zviwedzere kushanda kwayo. Maitiro aya ekuchenesa anovimbisa kuti mabhedhi emwenje e LED anopa kupenya kwakanyanya, kuenderana kwemavara, uye kushanda zvakanaka kana zvichishandiswa. Mushure mekucheneswa, zvinhu izvi zvinochekwa kuita mawafer madiki uchishandisa muchina wekucheka wepamusoro.

Danho rinotevera mukugadzirwa kwaro rinosanganisira kugadzirwa kwemachipisi e LED pachawo. Mawafer aya anobatwa nemazvo nemakemikari chaiwo uye anoiswa muitiro unonzi epitaxy, umo zvikamu zve semiconductor material zvinoiswa pamusoro pewafer. Kuiswa uku kunoitwa munzvimbo inodzorwa uchishandisa matekiniki akadai se metal-organic chemical vapor deposition (MOCVD) kana molecular beam epitaxy (MBE).

Kana maitiro epitaxial apera, wafer inofanira kupfuura nematanho akatevedzana ephotolithography uye etching kuti ione chimiro cheLED. Maitiro aya anosanganisira kushandisa matekiniki epamusoro ephotolithography kugadzira mapatani akaomarara pamusoro pewafer anotsanangura zvikamu zvakasiyana zvechip yeLED, zvakaita senzvimbo dzep-type nen-type, active layers, uye contact pads.

Mushure mekunge machipisi e LED agadzirwa, anopinda muhurongwa hwekurongedza nekuyedza kuti ave nechokwadi chekuti ane hunhu hwakanaka uye anoshanda. Chipisi inoedzwa kuti ione hunhu hwemagetsi, kupenya, tembiricha yemavara, nezvimwe zvinodiwa kuti isvike pazvinodiwa. Machipisi asina kunaka anogadziriswa uku machipisi anoshanda achienda padanho rinotevera.

Padanho rekupedzisira rekugadzirwa, machipisi e LED anoiswa mumabhedhi ekupedzisira emwenje ye LED. Maitiro ekurongedza anosanganisira kuisa machipisi pafuremu ye lead, kuabatanidza nemagetsi, uye kuafukidza ne resin inodzivirira. Kurongedza uku kunodzivirira chipisi kubva kuzvinhu zvakatipoteredza uye kunowedzera kugara kwayo kwenguva refu.

Mushure mekurongedza, mabhero emwenje e LED anoongororwazve mashandiro, kugara kwenguva refu, uye kuvimbika. Miedzo iyi inotevedzera mamiriro chaiwo ekushanda kuitira kuti ive nechokwadi chekuti mabhero emwenje e LED anoshanda zvakanaka uye anogona kutsungirira zvinhu zvakasiyana-siyana zvakaita sekuchinja-chinja kwekushisa, hunyoro, uye kudedera.

Kazhinji, maitiro ekugadzira mabhero emwenje e LED akaomarara zvikuru, anoda michina yepamusoro, kudzora kwakaringana, uye kuongororwa kwakasimba kwemhando. Kufambira mberi muhunyanzvi hwe LED uye kugadzirisa maitiro ekugadzira kwakabatsira zvikuru mukuita kuti mhinduro dzemwenje dze LED dzive dzinochengetedza simba zvakanyanya, dzakasimba, uye dzakavimbika. Nekutsvaga nekuvandudza kuri kuramba kuchiita basa iri, maitiro ekugadzira anotarisirwa kuvandudzwa zvakanyanya, uye mabhero emwenje e LED achava anoshanda zvakanyanya uye anodhura zvishoma mune ramangwana.

Kana uchifarira maitiro ekugadzira mabheya emwenje e LED, gamuchira kuti ubate mugadziri wemwenje wemugwagwa we LED TIANXIANG kuti akubatsire.verenga zvakawanda.
