Ts'ebetso ea tlhahiso eaLifaha tsa mabone tsa LEDke sehokelo sa bohlokoa indastering ea mabone a LED. Lifaha tsa mabone a LED, tse tsejoang hape e le li-diode tse ntšang leseli, ke likarolo tsa bohlokoa tse sebelisoang lits'ebetsong tse fapaneng ho tloha mabone a bolulo ho ea ho litharollo tsa mabone a likoloi le a indasteri. Lilemong tsa morao tjena, ka lebaka la melemo ea ho boloka matla, bophelo bo bolelele, le tšireletso ea tikoloho ea lifaha tsa mabone a LED, tlhoko ea tsona e eketsehile haholo, e leng se lebisang tsoelo-peleng le ntlafatsong ea theknoloji ea tlhahiso.
Ts'ebetso ea tlhahiso ea lifaha tsa mabone a LED e kenyelletsa mekhahlelo e mengata, ho tloha tlhahisong ea thepa ea semiconductor ho isa kopanong ea ho qetela ea li-chips tsa LED. Ts'ebetso e qala ka khetho ea thepa e hloekileng haholo joalo ka gallium, arsenic le phosphorus. Lisebelisoa tsena li kopantsoe ka litekanyo tse nepahetseng ho etsa likristale tsa semiconductor tse thehang motheo oa theknoloji ea LED.
Kamora hore thepa ea semiconductor e lokisoe, e feta ts'ebetsong e thata ea ho hloekisa ho tlosa litšila le ho ntlafatsa ts'ebetso ea eona. Ts'ebetso ena ea ho hloekisa e netefatsa hore lifaha tsa mabone a LED li fana ka khanya e phahameng, botsitso ba 'mala le katleho ha li sebelisoa. Kamora ho hloekisa, thepa e sehoa ka li-wafer tse nyane ho sebelisoa sehahi se tsoetseng pele.
Mohato o latelang ts'ebetsong ea tlhahiso o kenyelletsa ho etsoa ha li-chips tsa LED ka botsona. Li-wafer li phekoloa ka hloko ka lik'hemik'hale tse itseng 'me li feta ts'ebetsong e bitsoang epitaxy, moo mekhahlelo ea thepa ea semiconductor e kenngoang holim'a wafer. Ho kenngoa hona ho etsoa tikolohong e laoloang ho sebelisoa mekhoa e kang metal-organic chemical vapor deposition (MOCVD) kapa molecular beam epitaxy (MBE).
Kamora hore ts'ebetso ea epitaxial e phethe, wafer e hloka ho feta letotong la mehato ea photolithography le ho fata ho hlalosa sebopeho sa LED. Ts'ebetso tsena li kenyelletsa ts'ebeliso ea mekhoa e tsoetseng pele ea photolithography ho theha lipaterone tse rarahaneng holim'a wafer tse hlalosang likarolo tse fapaneng tsa chip ea LED, joalo ka libaka tsa mofuta oa p le mofuta oa n, likarolo tse sebetsang, le li-contact pad.
Kamora hore di-chip tsa LED di etswe, di feta tshebetsong ya ho hlopha le ho lekola ho netefatsa boleng le tshebetso ya tsona. Di-chip di lekoa bakeng sa dibopeho tsa motlakase, kganya, mocheso wa mmala, le diparamente tse ding ho fihlela maemo a hlokahalang. Di-chip tse nang le sekoli di a hlophiswa ha di-chip tse sebetsang di ya mohatong o latelang.
Mokhahlelong oa ho qetela oa tlhahiso, li-chip tsa LED li kenngoa ka har'a lifaha tsa mabone a LED tsa ho qetela. Ts'ebetso ea ho paka e kenyelletsa ho kenya li-chip foreiming ea loto, ho li hokahanya le likhokahano tsa motlakase, le ho li koahela ka har'a thepa e sireletsang ea resin. Sephutheloana sena se sireletsa chip ho lintho tse tikolohong 'me se eketsa ho tšoarella ha eona.
Kamora ho paka, lifaha tsa mabone a LED li etsoa liteko tse ling tse sebetsang, tse tšoarellang le tse tšepahalang. Liteko tsena li etsisa maemo a sebele a mosebetsi ho netefatsa hore lifaha tsa mabone a LED li sebetsa ka botsitso 'me li ka mamella lintlha tse fapaneng tsa tikoloho tse kang ho feto-fetoha ha mocheso, mongobo le ho thothomela.
Ka kakaretso, ts'ebetso ea tlhahiso ea lifaha tsa mabone a LED e rarahane haholo, e hloka mechini e tsoetseng pele, taolo e nepahetseng, le tlhahlobo e tiileng ea boleng. Tsoelo-pele theknolojing ea LED le ntlafatso ea lits'ebetso tsa tlhahiso li kentse letsoho haholo ho etseng hore litharollo tsa mabone a LED li boloke matla haholoanyane, li tšoarelle nako e telele, 'me li tšepahale. Ka lipatlisiso le nts'etsopele e tsoelang pele tšimong ena, ts'ebetso ea tlhahiso e lebelletsoe ho ntlafatsoa le ho feta, 'me lifaha tsa mabone a LED li tla ba le katleho e kholo le theko e tlase nakong e tlang.
Haeba o na le thahasello ts'ebetsong ea tlhahiso ea lifaha tsa mabone a LED, re u amohela ho ikopanya le moetsi oa mabone a seterata a LED TIANXIANG hobala haholoanyane.
