Nzira yekugadzira yeMwenje we LED mabhedhichinhu chakakosha chinongedzo muindasitiri yemwenje ye LED. Mabhedha emwenje e LED, anozivikanwawo semalight emitting diode, zvinhu zvakakosha zvinoshandiswa mumhando dzakasiyana siyana kubva pakuvhenekesa kwekugara kusvika kune mota uye maindasitiri emwenje mhinduro. Mumakore achangopfuura, nekuda kwezvakanaka zvekuchengetedza simba, hupenyu hurefu, uye kuchengetedzwa kwezvakatipoteredza kwemwenje we LED mabheji, kudiwa kwavo kwakawedzera zvakanyanya, zvichikonzera kufambira mberi nekuvandudzwa kwehunyanzvi hwekugadzira.
Maitiro ekugadzira emarambi e LED mabheji anosanganisira akawanda matanho, kubva pakugadzira semiconductor zvinhu kusvika kumusangano wekupedzisira we LED machipisi. Iyo nzira inotanga nekusarudzwa kwepamusoro-kuchena zvinhu zvakadai se gallium, arsenic, uye phosphorus. Zvinhu izvi zvinosanganiswa muzvikamu chaizvo kuti zvigadzire semiconductor makristasi anoumba hwaro hwe LED tekinoroji.
Mushure mekunge iyo semiconductor zvinhu yagadzirwa, inoenda nenzira yakasimba yekucheneswa kubvisa tsvina uye kuwedzera kushanda kwayo. Iyi nzira yekuchenesa inova nechokwadi chekuti mwenje wemwenje we LED unopa kupenya kwepamusoro, kuenderana kwemavara, uye kugona kana uchishandiswa. Mushure mekucheneswa, zvinhu zvacho zvinochekwa kuita zvimedu zvidiki uchishandisa chemberi chekucheka.
Nhanho inotevera mukuita kwekugadzira inosanganisira kugadzirwa kweiyo LED machipi ivo pachavo. Iwo mawafesi anonyatso batwa nemakemikari chaiwo uye anopinda maitiro anonzi epitaxy, umo maturu e semiconductor zvinhu anoiswa pamusoro pechingwa. Kuiswa uku kunoitwa munzvimbo inodzorwa pachishandiswa matekiniki akadai sesimbi-organic chemical vapor deposition (MOCVD) kana molecular beam epitaxy (MBE).
Mushure meiyo epitaxial process yapera, iyo wafer inoda kupfuura neyakatevedzana yephotolithography uye etching matanho ekutsanangura chimiro che LED. Aya maitiro anosanganisira kushandiswa kwehunyanzvi hwekuita photolithography kugadzira mapatani akaomarara pamusoro peiyo wafer inotsanangura zvakasiyana-siyana zvikamu zve LED chip, senge p-mhando uye n-mhando matunhu, anoshanda akaturikidzana, uye mapedhi ekusangana.
Mushure mekunge machipisi e LED agadzirwa, vanoenda nenzira yekurongedza uye yekuyedza kuti ive nechokwadi chemhando yavo nekuita. Iyo chip inoedzwa hunhu hwemagetsi, kupenya, tembiricha yemavara, uye mamwe ma parameter kuti asangane nezvinodiwa. Akaremara machipisi anorongedzerwa apo anoshanda machipisi anoenda kune rinotevera nhanho.
Muchikamu chekupedzisira chekugadzirwa, machipisi e LED anoiswa mumagetsi ekupedzisira emarambi e LED. Maitiro ekurongedza anosanganisira kukwirisa machipisi pane inotungamira furemu, achiabatanidza kune emagetsi mabatiro, uye nekuaputira mune inodzivirira resin zvinhu. Uku kurongedza kunodzivirira chip kubva kune zvakatipoteredza zvinhu uye inowedzera kusimba kwayo.
Mushure mekurongedza, marambi emwenje e LED anoiswa kune yekuwedzera kushanda, kusimba, uye kuvimbika bvunzo. Iyi bvunzo inoteedzera mamiriro chaiwo ekushanda kuti ave nechokwadi chekuti marambi emwenje e LED anoita zvakatsiga uye anogona kumira zvakasiyana siyana kwezvakatipoteredza zvakaita sekuchinja kwekushisa, humidity, uye vibration.
Pakazere, maitiro ekugadzirwa kwemarambi e LED akaomesesa, anoda michina yepamberi, kunyatso kudzora, uye kuomarara kwemhando yekuongorora. Kufambira mberi mune tekinoroji yeLED uye optimization yemaitiro ekugadzira zvakabatsira zvakanyanya mukuita kuti zvigadziriso zvemwenje zve LED zvive nesimba-rinoshanda, rinogara, uye rakavimbika. Nekuenderera mberi nekutsvagisa nekusimudzira mundima iyi, maitiro ekugadzira anotarisirwa kuwedzera kuvandudzwa, uye marambi emwenje e LED achave akanyanya kushanda uye anokwanisika mune ramangwana.
Kana iwe uchifarira magadzirirwo emagetsi emarambi e LED, unogamuchirwa kubata mwenje wemwenje we LED mugadziri TIANXIANG kuverenga zvimwe.
