Hōʻike Hōʻikeʻike kala (CRI) Vs ka Mahana kala

I nā makahiki i hala iho nei, ua huikau piha e pili ana i ka ʻokoʻa ma waena o ka papa kuhikuhi kala a me ka mahana kala. Akā ma kēia ʻatikala, e wehewehe mākou i kāu mau kānalua e pili ana i nā mea ʻelua a maʻalahi i kou ʻike ʻana i kēia.

He aha ke kala ma ka laulā?

ʻO ka waihoʻoluʻu wale nō ka waiwai o ka mālamalama i ʻike ʻia e ka maka. He mea nui e hoʻomaopopo ʻo nā mea ʻoi loa i waiho ʻia i loko o kahi lumi pouli ʻaʻohe kala. No laila, ʻo ka māmā ka mea nui o ka hoʻoholo ʻana inā hiki iā ʻoe ke ʻike i ke kala.

He aha ka papa kuhikuhi kala (CRI)?

ʻO ka wehewehe maʻalahi ka hiki i kahi kumu kukui ke hōʻike pololei i nā alapine hiki ke hoʻohālikelike ʻia me ka mahana kala. ʻO 1-100 kona pae helu kūpono. Loaʻa i ka lā maoli kahi CRI a hiki i ka 100, ʻoiai nā kukui LED o kēia manawa mai 75 a 90. Ma ke ʻano laulā, ʻoi aku ka nui o nā CRI kiʻekiʻe.

ʻO ka haʻahaʻa o ka CRI, ʻoi aku ka haʻahaʻa o ka pololei o ka hoʻohua kala. ʻO kahi kumu māmā me kahi radiator wela e loaʻa i kahi CRI ma kahi o 100 no ka mea ua hōʻike like ʻia nā kala āpau i ka spectrum CRI i kona ʻano. No ka laʻana, hiki iā ʻoe ke ʻike i ka ʻōleʻa "burgundy" i ka lā, a loaʻa iā lākou kahi waihoʻoluʻu "ʻeleʻele" ma lalo o nā kukui CRI haʻahaʻa. He aha ka mea nui? No nā hanana kūikawā e like me nā hale kiʻi kiʻi a me nā hale hōʻikeʻike, pono ke kukui i kahi CRI a hiki i 95+ e hiki ai i nā malihini ke ʻike i nā kala "ʻoiaʻiʻo".

He aha ka mahana kala?

Ua wehewehe ʻia ʻo ia ke ala maʻalahi e wehewehe i nā ʻano kala like ʻole o ka mālamalama; ʻo ia nā leo mahana (nā leo melemele) a me nā leo ʻoluʻolu (nā leo uliuli) i ana ʻia ma nā degere Kelvin.

ʻO ke kiʻekiʻe o ke degere Kelvin, ʻoi aku ka keʻokeʻo o ka mahana kala. Eia naʻe, ʻoi aku ka mālamalama o ke kukui keʻokeʻo ma mua o ke Kelvin haʻahaʻa.

No laila, pili ka CRI i ke kala o ka mea a mākou e ʻike ai, a ʻo ka mahana o ka waihoʻoluʻu ke kala o ke kukui i hoʻokuʻu ʻia. He mau palena likeʻole lākou e wehewehe ana i keʻano o ke kumu kukui.

Pehea e hoʻohana ai i nā kukui ma nā wahi ʻoihana?

1. Kaʻa kaʻa

He 2700K ka wela o ka waihoʻoluʻu a me ka 80-CRI e holo ana i ke kahua kaʻa, a ʻoi aku ka maikaʻi o nā kukui ʻē aʻe no kēlā me kēia. ʻOi aku ka palekana no nā mea hoʻokele a me ka poʻe hele wāwae, ʻaʻole wale kekahi mau kukui ʻē aʻe, hiki ke alakaʻi i nā pōʻino a me ka ʻaihue. ʻO ka mea nui i ka hoʻomālamalama ʻana o ke kahua kaʻa, ʻo ia ka hoʻomālamalama maikaʻi ʻana i ka pō e hōʻemi i ka nui o nā pōʻino a me nā hewa e kū mai ana. Hoʻohana ka hapa nui o nā kaʻa kaʻa i nā kukui 2700 a 3500K (mahana) a me 65 a 80 CRI.

ʻO kekahi o nā mea e hoʻomanaʻo ai nā kānaka e pili ana i nā ʻoiaʻiʻo o ka pollution māmā. Mai ka neʻe ʻana o nā holoholona honua like ʻole a hiki i ka neʻe ʻana o nā manu nui, hoʻopilikia ka pollution māmā i ke ʻano ma nā ʻano like ʻole. He hopena nui kēia mau mea ola, ʻoi aku ka maikaʻi ʻole, no laila ke hoʻoweliweli nei i ko lākou ola. Hoʻopili pololei ʻia a pili ʻole paha ke kanaka. Ua loli nui ka circadian rhythms o kekahi mau holoholona. No laila, pono e mālama i ke koho ʻana i ke kukui kūpono.

2. kahua pōpeku

Pono nā kahua pāʻani pôpeku e hoʻohana i nā mahana kala kiʻekiʻe a me nā kukui CRI. I kēia manawa, ʻoi aku ka kaulana o ka pôpeku maʻamau ma mua o ka wā. No laila, i mea e pāʻani maikaʻi ai i ka pāʻani, pono e hōʻike piha a pololei i ke kahua. ʻIke loa, ʻoi aku ka maikaʻi o nā kukui CRI kiʻekiʻe i ka wā hoʻolaha a me nā pāʻani i hōʻike ʻia ma mua o ka maʻamau. Eia naʻe, pono e lawa nā kukui i nā pāʻani ʻē aʻe e pāʻani pono ai i ka pāʻani. Pono nā maka e like me ka ʻoluʻolu a me ka ʻike maka, ʻoi aku hoʻi i nā haʻuki kahi o ka wahi noho maoli.
