Isimiso esiyisisekelo nokusetshenziswa kwama-red leds

Ukukhanya okukhanyisayo ama-diode (amalambu aholwayo) aguqule imboni yokukhanyisa ngokusebenza kwawo kwamandla, isikhathi sokuphila isikhathi eside, kanye nokuguquguquka okuhlukahlukene. Phakathi kwemibala ehlukahlukene etholakalayo, ama-LED abomvu abamba indawo ekhethekile ngenxa yezakhiwo zawo ezihlukile nezinhlelo zokusebenza ezisabalele. Lo mbhalo uhlose ukuhambisa umgomo oyisisekelo ngemuva kwama-LED abomvu, ukwakhiwa kwabo, nokuhlola ukusetshenziswa kwawo okuhlukahlukene kuwo wonke amasimu ahlukahlukene.
Isigaba 1: Isisekelo esiyisisekelo se-LED ebomvu (faka i-LED ebomvu ye-SMD ne-Red Phole LED)
1.1 I-semiconductor physics:
Ukuqonda umgomo we-LED Red (625nm LED, 635NM LED), kufanele siqale siqonde izisekelo ze-semiconductor physics. I-Semicondectors izinsiza ezinokuphamba kukagesi phakathi kwabaqhubi (njengezinsimbi) nabangewona abaqhubi (njengama-insulance). Ukuziphatha kwama-semiconductors kulawulwa ukunyakaza kwama-elektroni ngaphakathi kwesakhiwo sabo se-athomu.

1.2 I-PN Junction:
Ingxenye esemqoka ye-LED yi-PN Junction. Kwakhiwa ngokujoyina izinhlobo ezimbili ezihlukene zama-semiconductors: P-Type (DED) no-N-Type (negative). I-semiconductor ye-P-Tycond inentsheli yabathwali abaphethe amangalo (izimbobo), ngenkathi uhlobo lwe-n-semiconductor linentshontsho ebilayo labathwali abangenacala (ama-elektroni).
1.3 ElectrolUminescence:
Lapho i-froad voltage isetshenziswa ngaphesheya kwe-PN Junction, ama-elektroni avela esifundeni se-N-Type kanye nezimbobo ezivela esifundeni se-P-Type zihlanganise ekuhlanganeni, ukukhulula amandla ngendlela yama-photons. Le nto yaziwa ngokuthi i-electrollinescence. Amandla we-Photon akhishwe anquma umbala we-LED.

Isigaba 2: Ukwakhiwa kwama-LED abomvu
2.1 Izinto ezisetshenzisiwe:
Ama-Red Leds athathwa ngokujwayelekile usebenzisa inhlanganisela ye-gallium arsenide (gaas) kanye ne-aluminium gallium arsenide (algaas). Lezi zinto zokwenziwa zinikeza i-bandgap yamandla efanelekile yokuphuma kokukhanya okubomvu.
2.2 I-Epitaxy and Wafer FAFECICA:
Inqubo ye-Epitaxy ifaka ukukhulisa ungqimba oluncane lwe-semiconductor ebonakalayo ku-substrate. Endabeni ye-LED ebomvu, i-Epitaxy yenziwa nge-gallium arsenide subsTrate. Le ungqimba ifakwe lapho idala ama-chip aholwa ngamanye.
2.3 PN PN Junction Ukudalwa:
Ngenqubo yokudonsa, ukungcola kwethulwa kwizinto ze-semiconductor ukudala izifunda ze-P ne-N. Isifunda se-P sithathwa ngezinto ezinjenge-aluminium, ngenkathi isifunda se-N senziwe ngezinto ezinjenge-silicon.

2.4 Oxhumana Nama-Metal kanye Nomboleko:
Oxhumana nabo bensimbi bangezwa ezifundeni ze-P ne-N ukuvumela ukuxhumana kagesi. I-Chip ye-LED iphinde yahlotshiswa nge-resin esobala esobala, ukuqinisekisa ukuvikelwa kanye nokuthuthukisa ukuphuma okukhanyayo.
Isigaba 3: Ukusetshenziswa Kwe-LED ebomvu
3.1 Izibani zezinkomba:
Enye yezicelo ezivame kakhulu ze-RED LED zinjengezibani zezinkomba. Zisetshenziswa kabanzi kwi-elekthronikhi yabathengi, njengethelevishini, izinto zasekhaya, kanye namadeshi ezimoto. Ukusetshenziswa kwamandla okuphansi, usayizi we-compact, kanye nesikhathi eside sokuphila isikhathi eside yenza ama-LED abomvu alungele lezi zinhlelo zokusebenza.
3.2 Izimpawu zethrafikhi:
Ama-LED abomvu asetshenziswa kakhulu kumasiginali omgwaqo ngenxa yokubonakala kwawo okuphezulu nokwethembeka. Isibani esibomvu esikhanyayo esikhishwe yilezi zinhlaka ziqinisekisa ukubonakala okucacile ngisho nasezimweni zezulu ezingezinhle. Ngaphezu kwalokho, ukusetshenziswa kwawo kwamandla okuphansi kunciphisa izindleko zamandla nezidingo zokulungisa.

3.3 Ukukhangisa kanye Signage:
Ama-Red Leds aqashwa ekukhangiseni nasekubonisweni kwezimpawu ukuheha ukunakwa futhi adlulise imiyalezo ngempumelelo. Umbala wabo ogqamile kanye nekhono lokudala imiphumela yokukhanyisa elinamandla ukuze adume ukuze asetshenziswe kuma-billboards, izibonakaliso zesitolo, kanye nokuboniswa okukhulu.
3.4 Izicelo zezokwelapha:
Ama-Red LED athola izinhlelo zokusebenza ezinkambu zezokwelapha ezahlukahlukene. Zisetshenziswa ekwelashweni kwe-Photoynamic ukwelapha izinhlobo ezithile zomdlavuza, kanye nasekwelashweni kwe-laser okuphansi kokuphathwa kwezinhlungu nokuphulukiswa kwezilonda. Isimo esingahlaseli se-RED LED sibenza babaluleke ngokwelashwa kwezokwelapha.
3.5 Ukukhanyisa kwe-Horticulture:
Ama-Red Leds adlala indima ebalulekile ezinhlelweni zokukhanyisa ama-horticulture. Izitshalo zidinga ama-wavelength athile okukhanya ukuze akhule kahle ne-photosynthesis. I-Red LEDS ikhipha ukukhanya ohlwini lwama-600-700 nm, okubalulekile ekuvuseleleni ukukhula kwezitshalo, ukuqhakaza kanye nezithelo.

3.6 Ukuxhumana kwe-Optical:
I-Red LEDs isetshenziswa ezinhlelweni zokuxhumana ze-Optical, ikakhulukazi izinhlelo ezifuywayo ezifana nokudluliswa kwedatha okuvela phakathi kwamadivayisi. Ubukhulu babo obuhlanganisiwe, izindleko eziphansi, kanye nokuhambisana nemicu emihle kubenze balungele lezi zinhlelo zokusebenza.
3.7 Amadivayisi Wombono Webusuku:
Kusetshenziswa ama-LED abomvu kumadivayisi wokubuka ebusuku, anjenge-Goggles ye-Night Vision kanye nezinkawu. Isibani esibomvu esikhishwe yilezi zinhlaka mancane amathuba okuthi siphazamise umbono wobusuku bomsebenzisi uma kuqhathaniswa neminye imibala. I-Red Leds nayo inempilo yebhethri ende, ibenze balungele ukusetshenziswa okwengeziwe.
Isiphetho:
Ama-Red Leds asephenduke ingxenye ebaluleke kakhulu yezimpilo zethu zansuku zonke, ukuthola izinhlelo zokusebenza ezinhlobonhlobo zamasimu. Ukuqonda isisekelo esiyisisekelo ngemuva kokusebenza kwabo nokwakhiwa kusenza sikwazise ukukwazisa, ukuqina kanye nokuguquguquka okuhlukahlukene. Njengoba ubuchwepheshe buqhubeka buqhubekisa phambili, bomvu
