Yini Ebangela I-chip ye-LED emhlophe Ife?

Abakhiqizi abaningi bamane basebenzise izinto ezishibhile nezisezingeni eliphansi ukuze behlise intengo yezibani ukuze bahehe amakhasimende. Izinga lezikhalazo zekhwalithi mayelana nezibani zephaneli ze-LED EMHLOPHE linyukile eminyakeni emibili edlule ngenxa yalokhu. Ukuphuzi kwezibani zephaneli kungenye yazo, futhi kubi ngempela. Sizokhuluma ngezimbangela zokuthi kungani Mhlophe i-chip ye-LED emhlophe  fa. Ngaphandle kokuchitha isikhathi, masingene phakathi.

Yini? i-chip ye-LED emhlophe ?

Ukukhiqizwa kokukhanya okumhlophe ngama-LED EMHLOPHE kungenziwa ngezindlela ezimbili ezihlukene. Indlela ye-RGB ingeyokuqala, futhi indlela ye-phosphor ingeyesibili. Indlela ye-phosphor iyona evame ukusetshenziswa kakhulu emkhakheni wokukhanyisa. Indlela ye-phosphor idala iphakheji ye-LED EMHLOPHE ekhiqiza ukukhanya okumhlophe ngokumboza okuluhlaza okwesibhakabhaka i-chip ye-LED emhlophe nge-phosphor ephuzi.

Ukukhiqizwa kokukhanya okumhlophe ngama-LED EMHLOPHE kungenziwa ngezindlela ezimbili ezihlukene. Indlela ye-RGB ingeyokuqala, futhi indlela ye-phosphor ingeyesibili. Indlela ye-phosphor iyona evame ukusetshenziswa kakhulu emkhakheni wokukhanyisa.

Ngokumane uhlanganise izibani ezinombala obomvu, oluhlaza, noluhlaza okwesibhakabhaka ngezilinganiso ezifanele, ukukhanya okumhlophe kukhiqizwa kusetshenziswa indlela ye-RGB.

Indlela ye-phosphor idala iphakheji ye-LED EMHLOPHE ekhiqiza ukukhanya okumhlophe ngokumboza okuluhlaza okwesibhakabhaka i-chip ye-LED emhlophe  nge-phosphor ephuzi. Isendlalelo se-fluorescent esiphuzi sivumela ukukhanya okuluhlaza okwesibhakabhaka okukhiqizwa yi- i-chip ye-LED emhlophe  ukuze udlule, udala ukukhanya okumhlophe ngenhlanganisela yama-blues nama-photon aphuzi.

Ezingeni le-chip, i-light-emitting diode (i-LED) yakhiwe ngezinto ze-semiconductor ezenziwe nge-doped ukuze zakhe ukuhlangana kwe-p-n. Ngokusebenzisa ukuchema okuya phambili ekuhlanganeni, umuntu angaphoqa ama-electron ukuthi asuke ebhendini yokuqondisa yohlobo lwe-n aye ebhendini yokuqondisa yohlobo lwe-p. Lokhu kuhlanganiswa kabusha kuyinqubo yokukhipha imisebe okuthi, ezikhathini eziningi, kuphumele ekukhiqizweni kwe-photon enobude be-wavelength enqunywa i-bandgap yezinto.

Ngemuva kokwenziwa kwephethini ye-LED EMHLOPHE  I-wafer, iyasikwa ngokulandelayo, futhi umuntu oyedwa owenza i-wafer uyaxhunywa futhi apakishwe. Kuyadingeka ukuxhuma i-LED EMHLOPHE  ukuya emithonjeni kusetshenziswa izintambo ezinhle kakhulu, ezivame ukwakhiwa ngegolide, ukuze kukhiqizwe amandla oya phambili adingekayo ukuze kuphume ukukhanya ku-LED EMHLOPHE.

Kungani i-chip ye-LED emhlophe s Ukufa?

Ama-LED OMHLOPHE ngokuvamile ahlangabezana nenye yezinhlobo ezimbili eziyinhloko zokwehluleka: okuqhubekayo noma okuyinhlekelele. Ukuhluleka kwe-LED EMHLOPHE  kungenzeka kakhulu ukuthi kubangelwe ukuwohloka kancane ngokuhamba kwesikhathi ngokuphambene noguquko oluzumayo, ngaphandle kokumbalwa kakhulu. Ukwehluleka, emehlweni abathengisi, akusona isimo sezifunda ezimbili kodwa iphuzu elicacile ekuqhubekeni kwamazinga okusebenza. Ngokocwaningo, iso lomuntu likwazi kuphela ukubona ushintsho olungafika kumaphesenti angama-30 ekukhanyeni okukhanyayo ngaphambi kokuba ukukhishwa kwesibani kwehle ngaleyo ndlela. Njengomphumela walokhu, iningi labakhiqizi lichaza umjikelezo wempilo wedivaysi njengendawo lapho ukuphuma kwayo okukhanyayo kwehla ngaphansi kwamaphesenti angama-70 yenani ebinalo ekuqaleni.

Nokho, lokhu akusho ukuthi ukwehluleka okuyinhlekelele akusoze kwenzeka. Empeleni, amathuba okuthi enye yedivayisi yakho izoyeka ukusebenza kahle ngesikhathi esithile akhuphuka ngokulinganayo ngobunzima bezimo zokusebenza. Kukhona, nokho, izinyathelo ongazithatha ukuze unciphise umthelela walezi zici eziningi futhi wandise amathuba okuthi isicelo sakho samukelwe.

Ukwehluleka kwezinto

WHITE LED  ukusebenza kanye neminyaka yokuphila kuncike kwikhwalithi yezinto ezibonakalayo. Ukuhlanganiswa kabusha kwembobo ye-electron kuzodala ukubola okungashisi uma into inamaphutha amaningi. Ama-LED amaningi amhlophe anokukhanya okumhlophe akhiqizwa kuma-substrates esafire ambozwe nge-GaN. Ubunzima bokungafani kwe-lattice kudala ukugudluka kwentambo. Imifantu emihle isabalalisa ngokuma isuka kufilimu ye-GaN iye endaweni esebenzayo, okubangele ukubola okungeyona imisebe. Ukukhishwa kwesibani kuyehla njengoba ukubola okungeyona imisebe kuyanda. I-Thermocycling ingasabalalisa lezi ziphambeko.

Ukuvuza kwamanje okuvela kumaphutha esakhiwo kuvumele ukugeleza kwamanje kokuhlehla okuchemile. Umjovo wenkampani yenethiwekhi endaweni esebenzayo ungadala noma usakaze amaphutha. Ukuminyana kwesici kwehlisa i-voltage yokuphuka, kuthinte ukusebenza.

Amandla aphezulu angabangela izinkinga ku-p-side we-junction. Ingcindezi kagesi yonakalise i-ultraviolet EMHLOPHE ama-LED ngaphezu kwengcindezi eshisayo. Inkampani Zhuhai Tianhui Electronic Co., Ltd.   I-LED emhlophe epholile ilungele izinhlelo zokusebenza ezikhanya kakhulu. Idivayisi efakwe phezulu ingaphatha u-2.8 A wamanje oya phambili ngokukhipha okungu-900 lm.

Ukushayela ngokweqile i-LED EMHLOPHE

Ukushayela ngokweqile i-LED EMHLOPHE  ingalimaza okukhiphayo kanye nempilo yonke. Kuzinhlelo zokusebenza zokukhanya okuphezulu, cacisa idivayisi efana nale LED emhlophe qhwa, engakhipha 900 lm ku-2.8 A.

WHITE LED  amaphutha awagcini kumidiya esebenzayo. I-epoxy encapsulate ivikela ukufa, kodwa ingabangela izinkinga. Izinto ezimuncayo zingadlulisela umswakama noma amakhemikhali e-caustic ekufeni endaweni enomswakama noma eyonakalisayo. Oxhumana nabo abonakele bangakha izikhindi noma i-overvoltage. I-passivation inganciphisa lo mphumela, kodwa amadivaysi kufanele avikelwe ezimweni ezishisayo nezinomswakama.

Amaphutha kagesi

I-Electromigration, inqubo ezenzekelayo ethuthukiswa umswakama noma izimo ezimanzi, ingakhiqiza ngokuzenzekelayo imicu kusuka ezinsimbi njengesiliva ekunamathiselwe okusetshenziselwa ukunamathela ama-LED angaphezulu kwamabhodi. Gwema ama-LED angavaliwe.

WHITE LE D ukuchayeka ekukhishweni kwe-electrostatic high-voltage kungase kuhluleke ngendlela eyinhlekelele. I-Ultra-high-voltage spikes ijwayelekile. Ukuhamba ekamelweni elinokhaphethi kungakushaja kufika ku-1.5 kV, kuye ngomswakama nezicathulo. Lokho kushaqeka kunganqoba ukumelana ne-semiconductor ye-electrostatic uma ilethwa kufa. Ukushisisa okwedlulele kwasendaweni okuvela ekukhishweni kungabhoboza imidiya esebenzayo, kubangele ukwehluleka kwesiyingi esifushane.

Lapho Ukuthenga Emhlophe i-chip ye-LED emhlophe  Lokho Kuthatha Isikhathi Eside

Inkampani Zhuhai Tianhui Electronic Co., Ltd.  iyikhwalithi ephezulu UV Abakhiqizi be-LED  onguchwepheshe be-UV WHITE LED drive air sanitization, i-UV WHITE LED yokuhlanza amanzi edrayivu, i-UV WHITE LED yokuphrinta idrayivu yokwelapha, UV White LED diode , uv   Okuhola Moduli , nezinye izinto. Inengcweti yocwaningo nentuthuko kanye nezisebenzi zokufinyelela ukuze zinikeze amaklayenti Ukuhlelwa kwe-UV EMHLOPHE LED drive, futhi imikhiqizo yayo ithole ukugunyazwa kabanzi amaklayenti.

I-Tianhui Hardware ibiyingxenye yephakeji yedrayivu ye-UV EMHLOPHE ye-LED enochungechunge lwendalo olugcwele, ikhwalithi engaguquki nokuqina, nezintengo eziphansi. Izingxenye zifaka i-UVA, i-UVB, ne-UVC kusuka kumafrikhwensi amafushane kuya kumade kanye nolwazi oluphelele lweMisebe ye-UV ukusuka emandleni aphansi kuye phezulu.
