Ukukhanya Kwesiginali Yethrafikhi yomcibisholo 300mm
Amasignali akhethekile aziwa ngokuthi amarobhothi emicibisholo asetshenziselwa ukuqondisa ithrafikhi ezindaweni ezithile. Ukuchaza ngokusobala indlela yesokudla yezimoto ezijikela kwesokunxele, ziqonde, futhi kwesokudla kuwumsebenzi wazo omkhulu.
Ngokuvamile zikhomba ohlangothini olulodwa nomzila, zenziwe ngemicibisholo ebomvu, ephuzi, neluhlaza. Lapho umcibisholo ophuzi ukhanyisiwe, izimoto esezivele ziwela umugqa wokumisa zingase ziqhubeke, kanti ezingakenziwanga kufanele zime futhi zilinde; lapho umcibisholo obomvu ukhanyiswa, izimoto ezikuleyo ndlela kufanele zime futhi zingaweli umugqa; futhi lapho umcibisholo oluhlaza ukhanyiswa, izimoto eziya kuleyo ndlela zingase ziqhubeke.
Uma kuqhathaniswa namarobhothi ayindilinga, amalambu emicibisholo avimbela ngempumelelo izingxabano zethrafikhi ezimpambanweni zomgwaqo futhi anikeza izinkomba ezinembe kakhudlwana. Ziyingxenye ebalulekile yezinhlelo zezimpawu zomgwaqo wasemadolobheni futhi zivame ukusetshenziselwa ukuthuthukisa ukuhleleka kwethrafikhi nokuphepha emigwaqweni ehlehliswayo kanye nasezimpambanweni zomgwaqo eziyinkimbinkimbi.

Emigwaqweni yasemadolobheni, ukukhanya kwethrafikhi yomcibisholo ongu-300mm wosayizi omaphakathi uvame ukusetshenziswa. Izinzuzo zayo eziyinhloko wukusebenza, ukuguquguquka, nokubonakala, okwenza ifanele izimo eziningi zokuhlangana.
Ukucaca okulinganayo kanye nebanga lokubuka
Ngisho nasemini ekhanyayo, usayizi omaphakathi wephaneli yokukhanya engu-300mm kanye nokubekwa okulungile kophawu lomcibisholo ngaphakathi kwephaneli kuqinisekisa ukukhonjwa okulula. Kumabanga ajwayelekile okushayela emigwaqweni emikhulu yasemadolobheni neyesibili, ukukhanya kwayo okukhanyayo kufanelekile. Kusukela ebangeni lamamitha angu-50 kuya kwangu-100, abashayeli bangabona ngokucacile umbala wokukhanya nesiqondiso somcibisholo, okubavimbela ekwenzeni amaphutha ngenxa yezimpawu ezincane. Ukukhanya kwasebusuku kuqinisekisa ukubukeka okunokulinganisela nokushayela okunethezekile ngoba kokubili kungena kakhulu futhi akunamandla engeziwe ezimotweni ezisondelayo.
Ukuhambisana Okubanzi Nokufakwa
Ngenxa yesisindo sayo esimaphakathi, lesi sibani sesignali somcibisholo ongu-300mm asidingi ukuqiniswa okwengeziwe kwesigxobo. Ayibizi futhi kulula ukuyifaka, futhi ingafakwa ngokuqondile emishinini yesignali ehlanganisiwe, kubakaki be-cantilever, noma izigxobo zesignali zempambanomgwaqo. Ilungele yomibili imigwaqo emikhulu enemizila emine kuya kweyisithupha futhi ingahlangabezana nezidingo zokufakwa kweziphambanomgwaqo eziwumngcingo ezifana neminyango yendawo yokuhlala neyokuphuma kanye nemigwaqo yamagatsha. Iqeda isidingo sokulungisa usayizi wokukhanya wesignali ngokusekelwe kusayizi wempambanomgwaqo, enikeza ukuguquguquka okuphezulu nokunciphisa inkimbinkimbi yokuthengwa nokunakekelwa kukamasipala.
Izindleko Ezithuthukisiwe Zokusebenzisa Amandla Nezokulungisa
Izibani zesignali yethrafikhi yomcibisholo ongu-300mm ngokuvamile zisebenzisa imithombo yokukhanya ye-LED, zisebenzisa kuphela ingxenye eyodwa kwezintathu ukuya kwengxenye yamandla amalambu esignali endabuko, ehlisa kakhulu ukusetshenziswa kwamandla ngokuhamba kwesikhathi. Uma kuqhathaniswa namalambu amasignali amancane, anempilo ende yesevisi yeminyaka emihlanu kuya kweyisishiyagalombili ngenxa yedizayini yawo ehlangene kanye nokunqamuka kokushisa okuphakeme. Ukwengeza, izesekeli zazo ezihambisana kakhulu zenza kube lula ukushintsha izingxenye ezilimele njengephaneli kagesi nephaneli yokukhanya, okuholela kumjikelezo omude wokulungisa kanye nezindleko eziphansi, ukwehlisa izindleko zokusebenza zengqalasizinda yethrafikhi kamasipala.
Ukwengeza, uphawu lwesiginali yethrafikhi yomcibisholo ongu-300mm linosayizi omaphakathi, alikho likhulu kakhulu ukuthi lingathatha isikhala sepali esiningi kakhulu noma lincane kakhulu ukwenza kube nzima ngabahamba ngezinyawo noma izimoto okungezona izimoto ukuthi zilubone. Kuyisixazululo esithengekayo esinelisa izidingo zazo zombili izimoto ezihamba ngezimoto nezingezona izimoto. Isetshenziswa kaningi ezimpambanweni zomgwaqo ezahlukene zasemadolobheni, ithuthukisa ngempumelelo ukuphepha nokuhleleka kwezimoto.
1. Q: Lithini ibanga lokubonakala lamarobhothi wethrafikhi womcibisholo ongu-300mm?
IMPENDULO: Elangeni elikhanyayo, abashayeli bangakwazi ukubona ngokucacile umbala okhanyayo nomcibisholo oqonde ngqo kusuka kumamitha angu-50-100; ebusuku noma esimweni sezulu esinemvula, ibanga lokubonakala lingafinyelela kumamitha angu-80-120, lihlangabezane nezidingo zokubikezela ithrafikhi ezimpambanweni ezivamile.
2. Q: Yisiphi isikhathi sokuphila esijwayelekile sokukhanya, futhi ingabe ukugcinwa kulula?
A: Ngaphansi kokusetshenziswa okuvamile, isikhathi sokuphila singafinyelela eminyakeni engu-5-8. Umzimba wesibani unesakhiwo sokuchitha ukushisa okuhlangene kanye nezinga lokwehluleka eliphansi. Izingxenye zishintshashintsha kakhulu, futhi izingxenye ezilimele kalula njengephaneli yesibani namandla kagesi kulula ukushintshwa ngaphandle kwesidingo semishini ekhethekile.
3. Umbuzo: Uma kuqhathaniswa nokucaciswa okungu-200mm kanye no-400mm, yiziphi izinzuzo eziyinhloko zokukhanya kwesignali yethrafikhi yomcibisholo ongu-300mm?
A: Ukulinganisa "ukucaca" kanye "nokuhlukahluka": Inebanga elibanzi lokubonakala kuno-200mm, lilungele ukuphambana kwezindlela eziningi; ilula futhi iguquguquka kakhulu ekufakweni kuno-400mm, futhi inezindleko eziphansi zokusetshenziswa kwamandla kanye nokuthengwa kwempahla, okwenza kube ukucaciswa kosayizi omaphakathi ongabizi kakhulu.
4. Q: Ingabe ukukhanya nombala wezimpawu zomcibisholo kungaphansi kwezindinganiso ezifanayo?
A: Imithetho kazwelonke eqinile (GB 14887-2011) iyadingeka. Amaza abomvu angama-620-625 nm, amaza aluhlaza angama-505-510 nm, futhi amaza aphuzi angama-590-595 nm. Ukukhanya kwazo kungu-≥200 cd/㎡, okuqinisekisa ukubonakala ezimeni ezihlukahlukene zokukhanyisa.
5. Q: Ingabe isiqondiso somcibisholo singashintshwa ukuze sivumelane nezidingo zomgwaqo? Isibonelo, ukujika kwesokunxele + inhlanganisela eqondile-phambili?
A: Ukwenza ngendlela oyifisayo kuyenzeka. Imicibisholo eyodwa (kwesokunxele/iqondile/kwesokudla), imicibisholo ekabili (isb, jikela kwesokunxele + uqonde phambili), kanye nenhlanganisela yemicibisholo emithathu—engakwazi ukumataniswa kalula ngokuya ngemisebenzi yomzila wempambana-mgwaqo—ziphakathi kwezitayela ezisekelwa imikhiqizo evamile.
