He aha nā Lumens, a he mea pono anei ia no ka loiloi ʻana i nā kukui ulu?

ʻO nā lumens kahi ana oʻoluʻolu ʻālohilohi, a i ʻole ka nui o nā kukui ʻike ʻia mai kahi kumu,kaumaha ʻia e ka maka o ke kanaka i ka lōʻihi nalu o ka mālamalama.ʻO nā lumens ke ana maikaʻi loa e hoʻohana ai i ka loiloi ʻana i ka maikaʻi o ke kukui e hoʻomālamalama i kahi wahi no nā maka kanaka.ʻOi aku ka maʻalahi o ka maka o ke kanaka i ka mālamalama i ka laulā melemele a me ka ʻōmaʻomaʻo o ka spectrum, no lailaHe 100 kiʻi o ke kukui ʻōmaʻomaʻo i ʻoi aku ka nui o ka helu lumen ma mua o 100 photons o ke kukui uliuli a i ʻole 100 photons o ke kukui ʻulaʻula..

Makemake nā mea kanu i ka ʻulaʻula a me ka uliuli.ʻOi aku ka maikaʻi o ka lumens i ke kukui melemele a me ka ʻōmaʻomaʻo a me ke kukui ʻulaʻula a me ka polū,ka hana ʻana i nā lumens e pili ana i ke ana ʻoi loa o ka māmā no ka loiloi ʻana i ka maikaʻi o ka ulu ʻana o nā mea kanu.

Lumen Weighting (melemele) versus Photosynthetic Efficiency ('ōmaʻomaʻo):

ʻO ke ana ʻana o nā lumens i ʻike ʻia e ke kanakaʻoluʻolu ʻālohilohiʻokoʻa maiPAR / PPFD, e ana anaʻōlinolino- ka huina o nā kiʻi kiʻi i loko o ka spectrum ʻike ʻia me ke kaupaona ʻole no ka ʻike kanaka.Hāʻawi i ka Photon Flux (YPF)Ua like ia me nā lumens i loko o ia photons ua kaupaona ʻia ma muli o ko lākou nalu nalu, akā kaupaona ʻo YPF iā lākou ma muli o ko lākou pono i kahi mea kanu ma mua o ka maka kanaka, a manaʻo ʻo YPF i nā photons ma waho o ke ʻano ʻike kanaka.
