Ngaba inxenye ye-phailical ye-headlimp ibhetele ngelensi okanye indebe ekhanyayo?

Ukudada i-headlampsesinye sezixhobo ezisetyenziswa rhoqo kwimidlalo yokuntywila, enokubonelela ngomthombo wokukhanya, ukuze iimfesane ziyibone ngokucacileyo indawo ekufutshane nolwandle olunzulu. Inxalenye ye-Optical ye-Trive Chidibemp ibaluleke kakhulu yokumisela isiphumo sayo esikhanyayo, i-lens kunye nekomityi ekhanyayo zizinto ezimbini eziqhelekileyo. Ke, yintoni umahluko phakathi kokusetyenziswa kweelensi kunye neendebe ezikhanyayo kwi-thering yentloko?

Okokuqala, makhe sijonge umxholo osisiseko welensi kunye nekomityi yokukhanya. Ilensi yinto ekhethiweyo, "ekwaziyo ukujonga ukukhanya. Iyakwazi ukubonakalisa okanye ukungcungcutheka, ngaloo ndlela iguqula indlela kunye nokusasazwa kokukhanya." Ikomityi yokukhanya ngumvavanyi ophephe kwaye ugxile kwindawo ethile ukonyusa ukukhanya kunye nokugxila kokukhanya.

In I-EPED ye-EPHUSERDS enokuphinda isebenze, ilensi kunye nekomityi ekhanyayo ngokwahlukeneyo. Ilensi isetyenziselwa ukuhlengahlengisa isikhokelo sokusasazeka kunye nokusasazwa kokukhanya, ukuze ukukhanya kuhle ngakumbi ngaphambili kwebala. Iilensi zinokwenziwa ngokweemfuno, umzekelo, iilensi zeConvex zinokugxila ukukhanya zibe luluhlu oluncinci, ngaloo ndlela ziphucula ukuqaqamba kunye nokugxila kokukhanya; I-cocave iilensi inokusasaza ukukhanya, ivumela ukukhanya kukukhanyisa indawo ekufutshane. Ukukhetha kunye nokuyilwa kweelensi kufuneka kuthathelwe ingqalelo iimfuno zeI-Peleffimp yakhokelwakunye neempawu zendawo yokudada.

Ikomityi yokukhanya isetyenziselwa ukuphucula ukuqaqamba kunye nokugxila kokukhanya. Indebe yokukhanya inokubonakalisa kwaye ijonge ukukhanya ibe yindawo ethile, esenza ukukhanya ngakumbi kwaye kubi kakhulu. Uyilo kunye nokukhethwa kwezinto zekomityi ekukhanyiseni kunefuthe elibalulekileyo kwifuthe lokujonga kokukhanya. Ngokubanzi, enzulu ubume beNdebe ekhanyayo, elona qhina lujolise lokukhanya, kodwa kwangaxeshanye, liya kukhokelela ekubonakalisweni kwendlela encinci yokukhanya. Ke ngoko, ukukhetha iikomityi ezikhanyayo kufuneka zilungelelaniswe ngokweemfuno ze-goring yesihloko sentloko kunye neempawu zendawo yokudada.

Ilensi isetyenziselwa ukuhlengahlengisa isikhokelo sokusasazeka kunye nokusasazwa kokukhanya, ukuze ukukhanya kuhle ngakumbi ngaphambili kwebala. Ikomityi yokukhanya isetyenziselwa ukuphucula ukuqaqamba kunye nokugxila kokukhanya, ukwenza ukukhanya ngakumbi kwaye kubunzulu. Ukukhetha kunye nokuyilwa kweleyile kunye nekomityi ekhanyayo kufuneka kulinganiselwe kwiimfuno zeI-USB ye-USB iphinde isebenzekunye neempawu zendawo yokudada.

Ukongeza, ilensi kunye nekomikhi ekhanyayo ikwanomxholo othile kwisiphumo sokukhanya kweI-Expression yokuphinda isebenze. I-lensi yokuntywila inokutshintsha isiphumo sokugxila kokukhanya ngokuhlengahlengisa ubude kunye nokukhanya kwentloko yokudada kunokuyikhanyisela ngaphambili kwe-diver. Ikomityi ekhanyayo yeNdebe yeNtloko ephucula ubuqaqawuli kunye nokugxila kokukhanya kwesibane sokuntywila ngokubonisa ukukhanya kwaye kugxilise kwindawo ethile. Ke ngoko, i-lensi yokuntywila kunye nekhephu yekomikhi ekhanyayo ineempawu ezahlukeneyo kunye nezibonelelo kwimpembelelo yokukhanya.

Isishwankathelo, kukho umahluko othile ekusebenziseni iilensi kunye neekomityi zokukhanya kwi-righs yesikhungu. I-lensi yokuntywila isetyenziswa ikakhulu ukuhlengahlengisa isikhokelo kunye nokusasazwa kokukhanya, ukuze ukukhanya kwentloko yokuntywila kunokubukhanyisela phambili ngaphambili kwebala; Ikomityi yokukhanyaI-Waterproof yeNewproompisetyenziselwa ikakhulu ukuphucula ukuqaqamba kunye nokugxila kokukhanya. Ukhetho kunye noyilo lweelensi kunye ne-erhef ye-headrols yeNdebe yeNdlela kufuneka ilungelelaniswe ngokweemfuno ze-diver kunye neempawu zendawo yokudada. Nokuba yini i-lens dissids okanye indebe yekomityi ekhanyayo, ingamalungu afanelekileyo othintelayo kwisihloko sokuntywila, kwaye isicelo sabo sinokuphucula amava okhuseleko namava ahlukeneyo.
