Mokhoa oa tlhahiso eaLifaha tsa lebone la LEDke sehokelo sa bohlokoa indastering ea mabone a LED. Lifaha tse khanyang tsa LED, tse tsejoang hape e le li-light emitting diode, ke likarolo tsa bohlokoa tse sebelisoang lits'ebetsong tse fapaneng ho tloha ho mabone a bolulo ho isa ho tharollo ea 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 lebone la LED, tlhokahalo ea bona e eketsehile haholo, e lebisang tsoelo-pele le ntlafatso ea theknoloji ea tlhahiso.
Ts'ebetso ea tlhahiso ea lifaha tsa lebone la LED e kenyelletsa mekhahlelo e mengata, ho tloha ha ho etsoa thepa ea semiconductor ho ea kopanong ea ho qetela ea li-chips tsa LED. Mokhoa ona o qala ka khetho ea lisebelisoa tse hloekileng tse kang gallium, arsenic le phosphorus. Lisebelisoa tsena li kopantsoe ka tekanyo e nepahetseng ho etsa likristale tsa semiconductor tse etsang motheo oa theknoloji ea LED.
Kamora hore thepa ea semiconductor e lokisoe, e feta ts'ebetsong e matla ea tlhoekiso ho tlosa litšila le ho ntlafatsa ts'ebetso ea eona. Ts'ebetso ena ea tlhoekiso e netefatsa hore lifaha tsa lebone la LED li fana ka khanya e phahameng, ho tsitsisa mebala, le katleho ha li sebelisoa. Kamora ho hloekisoa, thepa e khaoloa ka li-wafers tse nyane ho sebelisa seha se tsoetseng pele.
Mohato o latelang oa ts'ebetso ea tlhahiso o kenyelletsa ho theha li-chips tsa LED ka botsona. Li-wafers li tšoaroa ka hloko ka lik'hemik'hale tse itseng 'me li etsoa ka mokhoa o bitsoang epitaxy, moo likaroloana tsa lisebelisoa tsa semiconductor li kenngoa holim'a sephaphatha. Deposition ena e etsoa sebakeng se laoloang ho sebelisoa mekhoa e kang metal-organic chemical vapor deposition (MOCVD) kapa molecular beam epitaxy (MBE).
Ka mor'a hore ts'ebetso ea epitaxial e phethoe, sephaphatha se hloka ho feta letotong la photolithography le mehato ea etching ho hlalosa sebopeho sa LED. Mekhoa ena e kenyelletsa tšebeliso ea mekhoa e tsoetseng pele ea photolithography ho etsa mekhoa e rarahaneng holim'a sephaphatha se hlalosang likarolo tse sa tšoaneng tsa chip ea LED, tse kang libaka tsa mofuta oa p le mofuta oa n, likarolo tse sebetsang, le li-pads tsa ho kopana.
Kamora hore li-chips tsa LED li hlahisoe, li feta ka mokhoa oa ho hlopha le ho etsa liteko ho netefatsa boleng ba tsona le ts'ebetso ea tsona. Chip e lekoa bakeng sa litšobotsi tsa motlakase, khanya, mocheso oa mebala le likarolo tse ling ho fihlela maemo a hlokahalang. Li-chips tse nang le phoso lia hlophisoa ha li-chips tse sebetsang li ea mothating o latelang.
Mokhahlelong oa ho qetela oa tlhahiso, li-chips tsa LED li phuthetsoe ka lifaha tsa lebone tsa ho qetela tsa LED. Ts'ebetso ea ho paka e kenyelletsa ho kenya li-chips holim'a foreimi ea lead, ho li hokahanya le likhokahano tsa motlakase, le ho li kenya ka har'a thepa e sireletsang ea resin. Sephutheloana sena se sireletsa chip ho tsoa linthong tsa tikoloho mme se eketsa ho tšoarella ha eona.
Kamora ho paka, lifaha tsa lebone la LED li beoa litekong tse ling tsa ts'ebetso, ho tšoarella le ho ts'epahala. Liteko tsena li etsisa maemo a sebele a ho sebetsa ho netefatsa hore lifaha tsa mabone a LED li sebetsa ka mokhoa o tsitsitseng 'me li khona ho mamella maemo a fapaneng a tikoloho joalo ka ho fetoha ha mocheso, mongobo le ho thothomela.
Ka kakaretso, ts'ebetso ea tlhahiso ea lifaha tsa lebone la LED e rarahane haholo, e hloka mechine e tsoetseng pele, taolo e nepahetseng, le tlhahlobo e tiileng ea boleng. Tsoelo-pele ea mahlale a LED le ntlafatso ea lits'ebetso tsa tlhahiso li tlatselitse haholo ho etsa hore tharollo ea mabone a LED e sebetse hantle, e tšoarelle ebile e ka tšeptjoa. Ka lipatlisiso tse tsoelang pele le nts'etsopele lefapheng lena, ts'ebetso ea tlhahiso e lebelletsoe ho ntlafatsoa le ho feta, 'me lifaha tsa mabone a LED li tla sebetsa hantle le ho theko e tlase nakong e tlang.
Haeba u thahasella mokhoa oa ho hlahisa lifaha tsa lebone la LED, u amohelehile ho ikopanya le moetsi oa leseli la seterateng la LED TIANXIANG hobala haholoanyane.
