Maopopo iā ʻoe ka "lumen" e ʻike pono ai ke kukui?

Ma ke kuai ana owahopoʻonā kukuiahoʻomoanaʻIke pinepine nā kukui i ka huaʻōlelo "lumen", maopopo iā ʻoe?

Lumens = Puana kukui.Ma nā huaʻōlelo maʻalahi, ʻo Lumens (i hōʻike ʻia e ka lm) he ana ia o ka nui o nā kukui ʻike ʻia (i ka maka kanaka) mai kahi kukui a i ʻole kumu kukui.

ʻO ka nui loamaʻamau ma wahohoʻomoanamāmā, ke kukui a i ʻole ke kukui uilaʻO nā kukui nā kukui LED, e hoʻohana ana i ka ikehu liʻiliʻi a no laila he haʻahaʻa watt-rating.ʻAʻole pili kēia i nā watts a mākou i hoʻohana ai no ke ana ʻana i ka ʻōlinolino kukui, no laila ke hoʻololi nei nā mea hana i nā lumens.

ʻO Lumen, kahi ʻāpana kino e wehewehe ana i ke kahe o ka mālamalama, ua helu ʻia e "lm", pōkole no "lumen".ʻO ke kiʻekiʻe o ka waiwai lumen, ʻoi aku ka mālamalama o ka puʻupuʻu.Inā ʻaʻole ʻoe maopopo e pili ana i nā helu lumen, hiki i kēia pakuhi o ka incandescent i nā kukui LED ke hāʻawi iā ʻoe i kahi ʻike.ʻO ia hoʻi, inā makemake ʻoe i kahi LED hiki ke hoʻokō i ka hopena o kahi kukui kukui 100W, koho i kahi LED 16-20W a loaʻa iā ʻoe ka ʻōlino like.

Ma waho, e like me nā ʻano hana like ʻole e pono ai nā pae lumen like ʻole, hiki iā ʻoe ke kuhikuhi i ka ʻikepili aʻe: hoʻomoana pō: ma kahi o 100 lumen night hiking, crossing (e noʻonoʻo ana i nā loli e like me ka ua a me ka noe): 200~500 lumen e pili ana ka holo ʻana a i ʻole nā ​​heihei pō ʻē aʻe: 500 ~ 1000 lumen ʻimi a hoʻopakele pō ʻoihana: ʻoi aku ma mua o 1000 lumen

E akahele i ka hoʻohana ʻananā kukui ma waho(ʻoi aku ka nui o nā lumens), mai kuhikuhi iā lākou i nā maka kanaka.Hiki ke hoʻopōʻino i nā maka o ke kanaka ke ʻālohilohi loa.
