Lapho i-lumen iphakama, i-headlamp ikhanya ngokwengeziwe?

I-Lumen iyisilinganiso esibalulekile semishini yokukhanyisa. Lapho i-lumen iphakama, i-headlamp ikhanya ngokwengeziwe?
Yebo, kukhona ubudlelwano obulinganayo phakathi kwe-lumen nokukhanya, uma zonke ezinye izici zifana. Kodwa i-lumen akuyona ukuphela kwesici sokukhanya.

Okubaluleke kakhulu ukukhetha i-headlamp ukwazi ukuthi ama-lumens (lm), okuthiwa ama-lumens ungawathatha njengokukhanya, ama-lumens angu-50 nama-300 lumens, ama-lumens angu-300 aphakeme kakhulu, inombolo ye-lumen iphezulu, iphezulu ukukhanya. Uma ufuna ukumba ukuthi iyini i-lumen, ukukhanya kokukhanya okubonakalayo okukhishwa emthonjeni wokukhanya.

Ngakho-ke, lapho izibani zangaphambili zigxile kakhulu, kungcono?
Akunjalo impela. I-pointer ye-laser igxile kakhulu, inamandla futhi ingena, kodwa kuphela lelo phuzu; ithoshi elinamandla lidubula kude, kodwa lidela indawo enkulu yokukhanyisa…ngakho yonke into imaphakathi. Ku-engeli yokugxila yesibani, sicabangela ububanzi obujwayelekile be-Engeli obubonakalayo beso lomuntu, futhi ikholomu yokukhanya ivumela umsebenzisi ukuthi abone indawo edingekayo ngaphandle kokuphendula i-engeli njalo. Eqinisweni, ukubona komuntu kuyindawo ebucayi enamadigri ayi-10, ama-10 ~ 20 degrees angakwazi ukubona kahle ulwazi, futhi ama-20 kuya ku-30 ​​degrees azwela kakhulu ezintweni eziguqukayo. Ngokusekelwe kulo mbono, singakwazi ukunquma ububanzi obufanele bokugxila kwekholomu yokukhanya kwekhanda.

Ngokwesimo sakho sokusebenzisa khetha iisibani esiphezulu se-lumens or isibani esiphansi se-lumens.

50-100Lumens
Ngokuvamile, kungcono ukuthi okungenani ube nezibani zangaphambili ze-lumen ezingama-50, ezilungele lesi simo: Joyina iklabhu yangaphandle enabaholi beqembu nabaqondisi Ukupheka, inkambu yokudlela.
100-200 Lumens
Izibani ze-lumen ezingaphezu kwe-100 zingakwazi ukubhekana nezimo eziningi, nakuba ukukhanya kusalinganiselwe, kodwa uma nje uhamba kancane, ngeke kube nenkinga enkulu kakhulu. Nokho, akukanconywa ukusebenza njengomholi weqembu. Isimo esisebenzayo: ikamu lokukhuphuka intaba Ukupheka, ukudla

Ngaphezu kwama-lumens angama-200, noma nangaphezulu300 lumens headlampingakuvumela ukuthi uhambe ebusuku, ngenxa yokukhanya kokukhanya okuphezulu, ukuze ukwazi ukubamba kangcono indawo ezungezile, imvelo yangaphambili, kodwa ukuphakama kwenani lelambu le-lumens liphezulu. Isimo esisebenzayo: ukukhuphuka intaba Emuva emfudlaneni Ukugijima okuningi ngaphandle komgwaqo.

Ngakho, Khetha isibani sakho manje!
