I-visor yakhelwe ukugwema ukugqama kwelanga futhi ivikele ithonya lelanga. Abanye bangahanjiswa emuva naphambili, ukuze balungise ukuvezwa kwelanga emehlweni, bagweme ukuvela kwezingozi, futhi ube nomphumela ongcono wokupholisa. Ingasetshenziswa ngaphakathi endlini, efana ne-visor yemoto: I-visor nayo yenza kube nzima ukuqondisa ukukhanya kwelanga emotweni, kodwa futhi futhi kungavikela ideshibhodi, isihlalo sesikhumba. Ilanga lingasetshenziswa futhi ngaphandle.
Ukusetshenziswa kwangaphandle
I-radius evunyelwe ye-curvature (R) kufanele ibe ngaphezu kwezikhathi eziyi-180 ubukhulu bepuleti.
Example: For example, if the 3mmPC board is used outdoors, its radius of curvature should be 3mm×180=540mm=54cm. Ngakho-ke, i-radius eklanyelwe i-curvature kufanele okungenani ibe ngu-54cm. Sicela ubheke etafuleni lemisebe yokugoba okuncane.
Ukusetshenziswa ngaphakathi
I-radius evunyelwe ye-curvature (R) kufanele ibe ngaphezu kwezikhathi eziyi-150 ubukhulu bepuleti.
