Izinzuzo kanye nokubi kwezibani zangaphambili ze-LED

Ama-light emitting diode (ama-LED) asetshenziswe kuma-radio electronics isikhathi eside. Lapho asetshenziswa, ngokwesibonelo, kuma-optical relays noma ama-optocouplers ukuze adlulisele isignali ngaphandle kokuthinta eshaneli yokubona. Izilawuli ezikude zezinto zikagesi zasekhaya nazo zithumela amasignali zisebenzisa ama-LED e-infrared. Amalambu okukhanya asetshenziselwa izinkomba kanye nokukhanyisa ezintweni zikagesi zasendlini kanye nazo zonke izinhlobo zamagajethi empeleni nawo ngokuvamile ama-LED. I-diode ekhipha ukukhanya iyisici se-semiconductor lapho, lapho okwamanje idlula ekuhlanganeni kwe-pn, ukuhlanganiswa kwe-electron-hole kwenzeka. Le nqubo ihambisana nokukhishwa kwama-photon okukhanya.

Naphezu kwekhono lokukhipha ukukhanya, ama-LED awakakasetshenziselwa ukukhanyisa. Kuze kube muva nje. Konke kwashintsha ngokufika kwezingxenye ezikhanya kakhulu, ezazifaneleka ekudaleni amadivaysi okukhanyisa. Kusukela ngaleso sikhathi, ubuchwepheshe bokukhanyisa okusekelwe ku-LED baqala ukungena ezimpilweni zethu futhi basusa ama-incandescent ama-bulb kuphela, kodwa futhi okuthiwa yiwo osindisa amandla.

Ukusetshenziswa kobuchwepheshe be-LED ezimotweni

Ukuphumelela kwezobuchwepheshe akuzange kuqashelwe abakhiqizi bezimoto. Ama-LED anamandla futhi ngesikhathi esifanayo enza kwaba nokwenzeka ukucisha izibani zangaphambili zemoto. Ekuqaleni baqala ukusetshenziselwa izibani zokupaka, izibani zamabhuleki, ukujika, bese kuba yizinsimbi eziphansi. Muva nje, sekuvele namalambu aphezulu e-LED. 

Uma ekuqaleni izibani ze-LED zifakwe kuphela kumamodeli abizayo, khona-ke muva nje, njengoba izindleko zobuchwepheshe sezishibhile, seziqalile ukubonakala nasezimotweni ezisezingeni eliphakathi. Kumamodeli wesabelomali, ukusetshenziswa kwama-LED kusakhawulelwe emithonjeni yokukhanya eyisizayo - isibonelo, indawo noma izibani ezisebenzayo.

Kodwa abathandi bokushuna sebenethuba elisha lokuhlukanisa imoto yabo kwezinye ngokukhanyiswa okumangalisayo kwe-LED yaphansi, uphawu nezinombolo. Umbala ungakhethwa ngokuthanda kwakho. Ngosizo lwemichilo ye-LED, kulula ukugqamisa isiqu noma ukubuyisela ngokuphelele ukukhanya ekhabetheni.

Idivayisi yokukhanya kwe-LED

Umgomo oyinhloko wabathuthukisi bamalambu emoto ukuhlinzeka ngebanga eliphezulu lokukhanya, kuyilapho besusa umphumela omangalisayo wabashayeli abazayo. Ikhwalithi, amandla kanye nokuqina nakho kubalulekile. Ubuchwepheshe be-LED bukhulisa kakhulu amathuba abaklami bezibani.

Nakuba i-LED eyodwa ingakhanyi kangako futhi ngisho nangaphezulu, ngenxa yobukhulu bayo obuncane, isethi yenqwaba yama-LED anjalo ingafakwa kusibani esikhulu. Ndawonye bazohlinzeka ngokukhanya okwanele kwendawo yomgwaqo. Kulesi simo, ukungasebenzi kahle kwengxenye eyodwa noma ezimbili ngeke kuholele ekuhlulekeni okuphelele kwesibani futhi ngeke kuthinte ngokujulile izinga lokukhanyisa.

Ikhwalithi enhle ye-LED iyakwazi ukusebenza amahora ayizinkulungwane ezingama-50. Lokhu kungaphezu kweminyaka emihlanu yomsebenzi oqhubekayo. Amathuba okwehluleka kwezingxenye ezimbili noma ngaphezulu kusibani esisodwa mancane kakhulu. Empeleni, lokhu kusho ukuthi cishe ngeke udinge ukushintsha ukukhanya okunjalo nhlobo.

Ukunikezwa kwamandla ekukhanyeni kwe-LED akuhlinzekwa ngokuqondile kunethiwekhi esebhodini, kodwa nge-stabilizer. Esimeni esilula, ungasebenzisa i-diode yokubuyisela kanye ne-resistor ekhawulela ukugeleza kwamanje ku-LED. Kodwa abakhiqizi bezimoto ngokuvamile bafaka iziguquli eziyinkimbinkimbi kakhulu ezandisa impilo yezingxenye ze-LED. 

Ukulawula okuzenzakalelayo kwezibani ze-LED

Ngokungafani nezibani ze-incandescent namalambu akhipha igesi, abonakala ngenye inertia, ama-LED avula futhi acime cishe ngokushesha. Futhi njengoba ukukhanya kwe-headlight kwakhiwa ukukhanya okukhanyayo kwezingxenye ngazinye, lokhu kwenza kube nokwenzeka ukujwayela ngokushesha ukukhanya kuye ngesimo sethrafikhi - ngokwesibonelo, shintsha usuka kubhamu oluphezulu uye kugongolo ophansi noma ucime izakhi ze-LED ngayinye ukuze njengokungajabulisi abashayeli bezimoto ezizayo.

Sezakhiwe izinhlelo ezikuvumela ukuthi ulawule amalambu ngokuzenzakalelayo, ngaphandle kokungenelela komuntu. Omunye wabo usebenzisa amakhethini, okuthi, ngosizo lwenjini kagesi, amboze ingxenye yama-LED. Amakhethini alawulwa yikhompyutha, futhi ukutholwa kwethrafikhi ezayo kwenziwa ngekhamera yevidiyo. Inketho ethakazelisayo, kodwa ebiza kakhulu.

Okuthembisayo okwengeziwe isistimu lapho i-elementi ngayinye inesithwebuli sezithombe esengeziwe esikala ukukhanya kwaso esimweni esingekho. Lesi sibani sangaphambili sisebenza ngemodi ye-pulsed. Ijubane eliphezulu likuvumela ukuthi uvule futhi uvale ama-LED ngefrikhwensi engabonakali ngeso lomuntu. Isistimu yokubona yesibani sangaphambili iklanyelwe.Kuvela ukuthi i-photocell ngayinye ithola ukukhanya kwangaphandle kuphela ukusuka ohlangothini lapho i-LED ehambisanayo ikhanya khona. Ngokushesha nje lapho i-photodetector ilungisa ukukhanya, i-LED izocisha ngokushesha. Kulolu khetho, akukho khompyutha, noma ikhamera yevidiyo, noma izinjini ezivuthayo zikagesi ezidingekayo. Akukho ukulungisa okuyinkimbinkimbi okudingekayo. Futhi-ke izindleko ziphansi kakhulu.

Izinzuzo

1. Izakhi ze-LED zincane. Lokhu kuvula inhlobonhlobo yohlelo lokusebenza, ukubekwa kanye namathuba okuklama.
2. Ukusetshenziswa kwamandla okuphansi nokusebenza kahle okuphezulu. Lokhu kunciphisa umthwalo ejeneretha futhi konga uphethiloli. Ukusebenza kahle kwamandla aphezulu kuzoba usizo ikakhulukazi ezimotweni zikagesi, lapho kuzosindisa amandla ebhethri.
3. Ama-LED empeleni awashisi, ngakho-ke inani elikhulu lezingxenye ze-LED lingafakwa kusibani esisodwa ngaphandle kwengozi yokushisa ngokweqile. 
4. Impilo ende yenkonzo - cishe iminyaka emihlanu yokusebenza okuqhubekayo. Ukuze uqhathanise: izibani ze-xenon azisebenzi amahora angaphezu kwezinkulungwane ezintathu, futhi izibani ze-halogen azivamile ukufinyelela inkulungwane.
5. Ukusebenza okuphezulu. Ukusabela okusheshayo kwamalambu amabhuleki e-LED uma kuqhathaniswa nalawo e-halogen kuthuthukisa ukuphepha kokushayela.
6. Ikhono lokudala amalambu ngokulawula ukukhanya okuzenzakalelayo kuye ngesimo somgwaqo.
7. Ikhwalithi ephezulu. Idizayini evaliwe yenza isibani sangaphambili singangeni manzi. Akakwesabi nokuvevezela nokuvevezela.
8. Amalambu e-LED nawo mahle ngokombono wemvelo. Aziqukethe izakhi ezinobuthi, futhi ukunciphisa ukusetshenziswa kukaphethiloli, futhi, kunciphisa inani lamagesi okukhipha amandla.

amaphutha

1. Ububi obukhulu bamalambu e-LED yizindleko eziphezulu. Nakuba iyehla kancane kancane, amanani asaluma kabuhlungu.
2. Ukushisa okuphansi kokushisa kugcina ingilazi yelambu langaphambili lipholile. Lokhu kuvimbela ukuncibilika kweqhwa neqhwa, okuthinta kabi ukusebenza kahle kokukhanyisa.
3. Umklamo we-headlight awuhlukaniseki, okusho ukuthi uma kwenzeka ukwehluleka kuyodingeka kushintshwe ngokuphelele.

isiphetho

Phakathi kwabashayeli, uthando lwamalambu e-xenon alukapheli, futhi ubuchwepheshe be-LED sebuvele buphezulu futhi buzwakala kakhulu. Izinzuzo zezibani ze-LED zisobala, futhi akungabazeki ukuthi ngokuhamba kwesikhathi zizothengeka futhi zizokwazi ukufaka esikhundleni sama-xenon nama-halogens.

Kanti endleleni kunamalambu ezimoto asebenzisa ubuchwepheshe belaser. Futhi amasampula okuqala asevele enziwe. Amalambu angaphambili e-laser, njengamalambu e-LED, anempilo ende yesevisi, futhi ayawedlula ngokwezinga lokukhanya. Kodwa-ke, asikho isidingo sokukhuluma ngabo ngokujulile okwamanje - ngokwezindleko, ukukhanya okukodwa okunjalo kuqhathaniswa nemoto entsha yezinga lesabelomali.
