Xa iphezulu ilume, kokukhona isibane siqaqamba ngakumbi?

I-Lumen ngumlinganiselo obalulekileyo wezixhobo zokukhanyisa. Xa iphezulu ilume, kokukhona isibane siqaqamba ngakumbi?
Ewe, kukho ubudlelwane obulinganayo phakathi kwe-lumen kunye nokukhanya, ukuba zonke ezinye izinto ziyafana. Kodwa i-lumen ayisiyiyo kuphela into ebonisa ukukhanya.

Eyona nto ibalulekileyo ukukhetha isibane sentloko kukwazi ukuba i-lumens (lm), into ebizwa ngokuba yi-lumens unokuyithatha njengokukhanya, 50 lumens kunye 300 lumens, 300 lumens ukuqaqamba kuphezulu, iphezulu inombolo yelumen, iphezulu ukuqaqamba. Ukuba ufuna ukugrumba kwinto eyi-lumen, kukukhanya kokukhanya okubonakalayo okuphuma kumthombo wokukhanya.

Ke, okukhona kugxininiswe ngakumbi izibane zentloko, kokukhona kungcono?
Akunjalo ncam. Isalathisi se-laser sigxininise kakhulu, sinamandla kwaye singena ngaphakathi, kodwa kuphela loo ngongoma; isibane esinamandla sidubula kude, kodwa sincama uninzi lwendawo yokukhanyisa…ngoko yonke into iphakathi. Kwingqwalasela ye-Angle ye-headlamp, siqwalasela uluhlu oluqhelekileyo lwe-Angle ebonakalayo yeso lomntu, kunye nekholomu yokukhanya ivumela umsebenzisi ukuba abone indawo efunekayo ngaphandle kokujika i-Angle rhoqo. Enyanisweni, umbono womntu ngummandla obuthathaka kwii-degrees ze-10, i-10 ~ 20 degrees inokuchonga ngokuchanekileyo ulwazi, kwaye i-20 ukuya kwi-30 degrees ivakalelwa ngakumbi kwizinto eziguquguqukayo. Ngokusekelwe kulo mbono, sinokumisela uluhlu olufanelekileyo lokugxila kwikholomu yokukhanya kwentloko.

Ngokwemeko yakho yosetyenziso khetha iisibane esiphezulu se-lumens or isibane esisezantsi se-lumens.

50-100Lumens
Ngokubanzi, kungcono ukuba ubuncinci ube nezibane zelumen ezingama-50, ezilungele le meko: Joyina iklabhu yangaphandle kunye neenkokeli zeqela kunye nezikhokelo Ukupheka, inkampu yokutyela.
100-200Lumens
Izibane ezingaphezulu kwe-100 zelumen ziyakwazi ukujamelana neemeko ezininzi, nangona ukukhanya kuncinci, kodwa nje ukuba uhamba ngokucothayo, akuyi kubakho ngxaki enkulu kakhulu. Nangona kunjalo, akukacetyiswa ukuba usebenze njengenkokeli yeqela. Imeko esebenzayo: inkampu yokukhwela intaba Ukupheka, ukutya

Ngaphezu kwe-200 lumens, okanye nangaphezulu300 lumens headlampinokukuvumela ukuba uhambe ebusuku, ngenxa yokukhanya kokukhanya okuphezulu, ukuze ukwazi ukuqonda ngcono indawo engqongileyo, indawo yangaphambili, kodwa ixabiso le-lumens headlamp liphezulu. Imeko esebenzayo: ukunyuka intaba Buyela kumsinga Ukubaleka ngakumbi kwendlela.

Ke, khetha isibane sakho ngoku!
