Izibani eziphansi zingabonakala yonke indawo ekuphileni kwethu kwansuku zonke. Kukhona futhi izinhlobo eziningiizibani eziphansi. Namuhla sizokhuluma ngomehluko phakathi kokukhanya kwenkomishi ekhanyayo kanye nokukhanya kwelensi.
Yini iLens?
Impahla eyinhloko ye-lens yi-PMMA, inenzuzo ye-plasticity enhle kanye nokudlulisa ukukhanya okuphezulu (kufika ku-93%). Ububi buwukumelana nezinga lokushisa eliphansi, cishe ama-degree angama-90 kuphela. Ilensi yesibili ivamise ukudizayina ngokubonisa okuphelele kwangaphakathi (TIR). Ilensi yakhelwe ngokukhanya okungena ngaphakathi ngaphambili, futhi indawo eyikholika ingaqoqa futhi ibonise konke ukukhanya okusemaceleni. Ukugqagqana kwezinhlobo ezimbili zokukhanya kungathola ukusetshenziswa kokukhanya okuphelele kanye nomphumela omuhle wendawo.
Yini i-TIR?
I-TIR ibhekisela “ku-Total Internal Reflection”, okuyisenzakalo esibonakalayo. Lapho umsebe ungena endaweni enenkomba ephezulu yokuphinda ikhanye ibe phakathi nendawo enenkomba ephansi ye-refractive, uma i-Angle yesigameko inkulu kune-Engle θc ebucayi (umsebe ukude nokujwayelekile), umsebe ophikisiwe uzonyamalala kanye naso sonke isigameko. i-ray izovezwa futhi ingangeni phakathi nendawo ngenkomba ephansi ye-refractive.
Ilensi ye-TIR: thuthukisa ukusetshenziswa kwamandla okukhanya kwe-LED
Ilensi ye-TIR yamukela umgomo wokuzindla okuphelele, owenziwe ngokuqoqa kanyeukukhanya kokucubungula. Idizayinelwe ukuthi igxile ekukhanyeni ngqo ngaphambili ngohlobo olungena ngaphakathi futhi indawo eyikholika ingaqoqa futhi ibonise konke ukukhanya okusemaceleni.. Ukugqagqana kwalezi zinhlobo ezimbili zokukhanya kungathola ukukhanya okuphelele ukuze kusetshenziswe kanye nomphumela omuhle wendawo.
Ukusebenza kahle kwelensi ye-TIR kungafinyelela ngaphezu kuka-90%, ngezinzuzo zokusetshenziswa kwamandla okukhanya okuphezulu, ukulahlekelwa ukukhanya okuncane, indawo encane yokuqoqa ukukhanya kanye nokufana okuhle, njll. Ilensi ye-TIR isetshenziswa ikakhulukazi kumalambu ama-angle amancane (i-beam Angle <60 °), njengezibani namalambu aphansi.
Yini i-reflector?
Inkomishi ekhumbuzayo iwukukhomba ukusebenzisa isibani somthombo wokukhanya njengomthombo wokukhanya, isibonisi esidinga ibanga ukuze siqoqe ukukhanya, ngokuvamile uhlobo lwenkomishi, oluvame ukwaziwa ngokuthi inkomishi ekhanyayo. Ngokuvamile, umthombo wokukhanya we-LED ukhipha ukukhanya ku-Engeli engaba ngu-120°. Ukuze kuzuzwe umphumela owufiswayo wokubona, isibani kwesinye isikhathi sisebenzisa isibonisi ukulawula ibanga lokukhanya, indawo yokukhanya, nomthelela wamabala.
I-Metal reflector: Idinga ubuchwepheshe bokugxiviza nokupholisha futhi inenkumbulo yokuguqulwa. Inzuzo yizindleko eziphansi kanye nokumelana nokushisa. Ivame ukusetshenziselwa imfuneko yokukhanyisa ebangeni eliphansi.
I-Plastiki Reflector: Kudingeka idemould eyodwa kuphela. Inzuzo ukunemba okuphezulu kwe-optical futhi ayikho inkumbulo yokuguqulwa. Izindleko zilinganiselwe futhi zifanele isibani ukuthi izinga lokushisa alikho phezulu. Ivamise ukusetshenziselwa imfuneko yokukhanyisa ebangeni eliphakathi neliphezulu.
Ngakho-ke yini umehluko phakathi kwelensi ye-TIR nenkomishi ekhanyayo? Eqinisweni, umgomo oyisisekelo wokusebenza kwawo uyafana, kodwa uma kuqhathaniswa, amalensi e-TIR anokulahlekelwa okuncane kwesixhumi esibonakalayo esibonakalayo.
Ilensi ye-TIR: Ukusebenzisana phakathi kobuchwepheshe bokuboniswa okuphelele kanye nendawo ephakathi, enokusabela ngokomzimba namakhemikhali. Umsebe ngamunye uyalawulwa futhi usetshenziswe, ngokuvamile ngaphandle kwamachashazi esibili, futhi uhlobo lokukhanya luhle. Ilensi iyindilinga futhi umsebe omaphakathi ufana kakhulu.Indawo ekhanyayo yelensi ifana ngokuqhathaniswa, unqenqema lwendawo yokukhanya iyindilinga, futhi uguquko lungokwemvelo. Ifanele indawo yesehlakalo enokukhanya okuphansi njengokukhanyisa okuyisisekelo, futhi ifanele indawo yesehlakalo enomklamo ofanayo. Indawo yelensi icacile, umugqa ohlukanisayo awubonakali, futhi ukukhanya kuhamba kancane kancane.
Bonisanoma: Isibani esihlanzekile sokulawula isibonisi. Kodwa uma kuqhathaniswaindawo yesibiliof ukukhanya kuyintoenkulu. Mukukhanya okukhanyayo ngokusebenzisa ukukhanya kwenkomishiiyangaphandle, ukukhanyauhlobo lunqunyiwengendebe.Ngosayizi ofanayo futhiaI-ngle yecala, ngoba ukukhanya kwe-interceptaI-ngle yenkomishi ekhanyayo inkulu, ngakho-ke i-anti glare izoba ngcono. Ingxenye enkulu yokukhanya ayixhumani ne-reflection surface ayilawulwa, indawo yesibili inkulu. Inkomishi ekhanyayo yokukhanya iphuma onqenqemeni futhiaInzwa ye-ngle inamandla ngokuqhathaniswa, isikhungo sokukhanya sinamandla futhi siya phambili.
Inkomishi ekhanyayo inendawo yokukhanya emaphakathi egxiliswe kakhudlwana kanye nomphetho omise okwe-V ohlanekezelwe, ofanele izigcawu ezinezinhlangothi ezincane ezivelele. Indawo yokukhanya yenkomishi ekhanyayo icacile, umugqa osikiwe wonqenqema lokukhanya usobala kakhulu.
Uma ubuza ukuthi yikuphi okungcono, ilensi ye-TIR noma iboniseor? Lokho kufanele kucatshangelwe ngezinjongo ezingokoqobo. Inqobo nje uma ingafinyelela umphumela optical oyifunayo, iyithuluzi elihle le-optical. Isibonelo, umthombo wokukhanya we-LED ngokuvamile ukhipha ukukhanya ku-Engeli engaba ngu-120°. Ukuze kuzuzwe umphumela owufiswayo wokubona, isibani kwesinye isikhathi sisebenzisa inkomishi ekhanyayo ukulawula ibanga lokukhanya, indawo yokukhanya, nomphumela wamabala okukhanya.
