Okukhona i-lumen iphezulu, kokukhona isibane sentloko sikhanya ngakumbi?

I-Lumen yindlela ebalulekileyo yokulinganisa izixhobo zokukhanyisa. Okukhona i-lumen iphezulu, kokukhona isibane sentloko sikhanya ngakumbi?
Ewe, kukho ubudlelwane obulinganayo phakathi kwe-lumen kunye nokukhanya, ukuba zonke ezinye izinto ziyafana. Kodwa i-lumen ayisiyo yodwa into ebangela ukukhanya.

Eyona nto ibalulekileyo ukukhetha isibane sentloko kukwazi ukuba ii-lumens (lm), ezibizwa ngokuba zii-lumens ungazithatha njengokukhanya, ii-lumens ezingama-50 kunye nee-lumens ezingama-300, ukukhanya kwe-lumens ezingama-300 kuphezulu, okukhona inani le-lumen liphezulu, kokukhona ukukhanya kuphezulu. Ukuba ufuna ukumba ukuba yintoni i-lumen, kukukhanya kokukhanya okubonakalayo okukhutshwa kumthombo wokukhanya.

Ngoko ke, xa izibane zezibane zigxile ngakumbi, kokukhona kungcono?
Akunjalo kanye. Isalathisi selaser sigxile kakhulu, sinamandla kwaye singena, kodwa kuphela loo ngongoma; ithotshi enamandla idubula kude, kodwa incama uninzi lwendawo yokukhanyisa… ngoko ke yonke into iphakathi. Kwi-engile ye-headlamp, sijonga uluhlu oluqhelekileyo lwe-engile ebonakalayo yeliso lomntu, kwaye ikholamu yokukhanya ivumela umsebenzisi ukuba abone indawo efunekayo ngaphandle kokujika i-engile rhoqo. Enyanisweni, umbono womntu yindawo ebuthathaka kwiidigri ezili-10, iidigri ezili-10 ~ 20 zinokuchonga ulwazi ngokuchanekileyo, kwaye iidigri ezingama-20 ukuya kuma-30 zibuthathaka ngakumbi kwizinto eziguqukayo. Ngokusekelwe kolu luvo, sinokumisela uluhlu olufanelekileyo lwekholamu yokukhanya yentloko.

Ngokwemeko yakho yokusetyenziswa, khethaisibane sentloko esine-lumens ephezulu or isibane sentloko esiphantsi se-lumens.

IiLumens ezingama-50-100
Ngokubanzi, kungcono ukuba nezibane ze-lumen ezingama-50 ubuncinane, ezifanelekileyo kwimeko enjalo: Joyina iklabhu yangaphandle eneenkokheli zeqela kunye nabaqondisi Ukupheka, inkampu yokutyela.
IiLumens ezili-100-200
Izibane ze-lumen ezingaphezu kwe-100 zinokukwazi ukumelana neemeko ezininzi, nangona ukukhanya kusancinci, kodwa logama nje uhamba kancinci, akuyi kubakho ngxaki inkulu kakhulu. Nangona kunjalo, akukhuthazwa ukuba usebenze njengenkokeli yeqela. Imeko esebenzayo: inkampu yokunyuka intaba Ukupheka, ukutya

Iilumens ezingaphezu kwama-200, okanye nangaphezuluIsibane sentloko se-lumens ezingama-300Ingakuvumela ukuba uhambe ebusuku, ngenxa yokukhanya okuphezulu, ukuze ukwazi ukuqonda ngcono imeko-bume ejikelezileyo, engaphambili, kodwa ixabiso lesibane se-lumens liphezulu. Imeko esebenzayo: ukunyuka intaba Ukubuyela emlanjeni Ukubaleka ngaphandle kwendlela.

Ngoko ke, khetha isibane sakho sentloko ngoku!
