He aha ka Color Rendering Index (CRI) a no ke aha he mea nui i ke kukui LED?
ʻAʻole hiki iā ʻoe ke ʻike i ka ʻokoʻa ma waena o nā socks ʻeleʻele a me nā kala kala i loko o kāu keʻena hele wāwae ma lalo o kāu mau kukui ʻālohilohi kahiko?Malia paha he haʻahaʻa haʻahaʻa CRI ke kumu kukui o kēia manawa.ʻO ka Papa kuhikuhi Hōʻikeʻike kala (CRI) kahi ana o ka hana ʻana o nā kala kūlohelohe ma lalo o kahi kumu kukui keʻokeʻo i hoʻohālikelike ʻia me ka lā.Ana ʻia ka helu helu mai ka 0-100, me ka 100 maikaʻi loa e hōʻike ana i nā kala o nā mea ma lalo o ke kumu kukui e like me nā kala ma lalo o ka lā maoli.ʻO nā CRI ma lalo o 80 ka mea i manaʻo ʻia he 'ʻilihune' aʻo nā pae ma luna o 90 i manaʻo ʻia he 'maikaʻi'.
ʻO nā kukui LED CRI kiʻekiʻe e hāʻawi i nā leo nani a me nā leo ʻōlinolino ma waena o ka spectrum kala piha.Eia naʻe, hoʻokahi wale nō ana o CRI no ka maikaʻi māmā.No ka hoʻomaopopo maoli ʻana i ka hiki o ke kumu kukui ke hana i nā kala āu e makemake ai, aia nā hoʻāʻo hohonu a mākou e hana ai a ʻōlelo ʻia e kā mākou mau ʻepekema kukui.E wehewehe hou aku mākou ma aneʻi.
He aha ka CRI e hoʻohana ai
Ke kūʻai a hoʻokomo ʻana i nā kukui LED keʻokeʻo, manaʻo mākou i kahi CRI ma luna o 90 akā ʻōlelo pū kekahi i kekahi mau papahana, hiki ke ʻae ʻia ka liʻiliʻi o 85.Aia ma lalo iho kahi wehewehe pōkole o nā pae CRI:
CRI 95 - 100 → Hōʻike kala kupaianaha.Hōʻike ʻia nā kala e like me ka mea e pono ai, puka mai nā leo maʻalahi a hoʻopaʻa ʻia, nani nā ʻili o ka ʻili, ola ke kiʻi, hōʻike nā ʻōpala a me nā pena i ko lākou mau kala maoli.
Hoʻohana nui ʻia i nā papa hana Hollywood, nā hale kūʻai kūʻai kiʻekiʻe, nā paʻi a me nā hale pena pena, nā hōkele hoʻolālā, nā hale kiʻi kiʻi, a me nā noi hale kahi e pono ai nā kala kūlohelohe e ʻālohilohi.
CRI 90 - 95 → ʻO ke kala kala nui!Aneane nā kala 'pop' a maʻalahi ke ʻike ʻia.Hoʻomaka ka kukui maikaʻi loa ma kahi CRI o 90. ʻO kāu backsplash kala-teal hou i hoʻokomo ʻia i loko o kāu lumi kuke e nānā nani, ʻoliʻoli, a piha piha.Hoʻomaka ka poʻe kipa e hoʻomaikaʻi i nā helu helu, pena, a me nā kikoʻī o kāu lumi kuke, akā liʻiliʻi lākou ʻo ka kukui ke kuleana no ka nani loa.
CRI 80 - 90 →ʻO ka hāʻawi kala maikaʻi, kahi i hāʻawi maikaʻi ʻia ka hapa nui o nā kala.ʻAe ʻia no ka nui o nā hoʻohana pāʻoihana.ʻAʻole ʻoe e ʻike i nā mea i piha piha e like me kou makemake.
CRI Ma lalo o 80 →ʻO ke kukui me kahi CRI ma lalo o 80 e manaʻo ʻia he maikaʻi ke kala kala.Ma lalo o kēia mālamalama, hiki ke nānā aku nā mea a me nā kala i ka desaturated, drab, a i kekahi manawa ʻike ʻole ʻia (e like me ka hiki ʻole ke ʻike i ka ʻokoʻa ma waena o nā soka kala ʻeleʻele a me ka navy).He mea paʻakikī ke hoʻokaʻawale i waena o nā kala like.
ʻO ke kala kala maikaʻi ke kī no ke kiʻi, nā hōʻikeʻike hale kūʻai kūʻai, nā kukui hale kūʻai, nā hōʻikeʻike kiʻi, a me nā kiʻi kiʻi no ka inoa ʻana i kekahi.Ma ʻaneʻi, ʻo kahi kumu kukui me kahi CRI ma luna o 90 e hōʻoia i ka nānā pono ʻana o nā kala i ke ʻano e pono ai, hoʻopuka pololei ʻia a ʻike ʻia a ʻoi aku ka māmā.He waiwai like ke kukui CRI kiʻekiʻe i nā noi hale, no ka mea hiki iā ia ke hoʻololi i kahi lumi ma ka hōʻike ʻana i nā kikoʻī hoʻolālā a me ka hana ʻana i kahi ʻoluʻolu, kūlohelohe maoli.ʻOi aku ka hohonu a me ka luster o nā hoʻopau.
Ka hoao ana no CRI
Pono ka hoʻāʻo ʻana no CRI i nā mīkini kūikawā i hoʻolālā ʻia no kēia kumu.I loko o kēia hoʻāʻo ʻana, ʻike ʻia ke kikoʻī māmā o ke kukui i ʻewalu kala like ʻole (a i ʻole "R values"), i kapa ʻia ʻo R1 a hiki i R8.
He 15 mau ana i hiki ke ike ia malalo iho, aka, ke hoohana wale nei ke ana CRI i ka 8 mua. "kūpono" a i ʻole "kumu" kumu kukui e like me ka lā o ka lā i ka mahana waihoʻoluʻu like.Hiki iā ʻoe ke ʻike mai nā hiʻohiʻona ma lalo nei, ʻoiai ʻo ke kiʻi ʻelua he CRI o 81, he mea weliweli ia i ka hoʻolilo ʻana i ke kala ʻulaʻula (R9).
Hoʻopaʻa inoa nā mea hana kukui i nā helu CRI ma kā lākou huahana, a ʻo nā hana aupuni e like me California's Title 24 e hōʻoia i ka hoʻokomo ʻana i nā kukui CRI kiʻekiʻe.
ʻOiai e hoʻomanaʻo ʻaʻole ʻo CRI ke ala kū hoʻokahi no ke ana ʻana i ka maikaʻi o nā kukui;ka Lighting Research Institute hōʻike pū kekahi i ka hoʻohana hui ʻana o TM-30-20 Gamut Area Index.
Ua hoʻohana ʻia ʻo CRI ma ke ʻano he ana mai ka makahiki 1937. Manaʻo kekahi poʻe he hewa a he kahiko ke ana ʻana o ka CRI, no ka mea, aia nā ala maikaʻi e ana i kēia manawa i ka maikaʻi o ka hāʻawi ʻana mai kahi kumu kukui.ʻO kēia mau ana ʻē aʻe ʻo Color Quality Scale (CQS), IES TM-30-20 me Gamut Index, Fidelity Index, Color Vector.
CRI - Papa kuhikuhi kala -Pehea ka pili pono o ka malamalama i ʻike ʻia i nā kala e like me ka lā, me ka hoʻohana ʻana i 8 mau laʻana kala.
ʻIkepili Pono (TM-30) –Pehea ka pili pono o ka malamalama i ʻike ʻia i nā kala e like me ka lā, me ka hoʻohana ʻana i 99 mau laʻana kala.
ʻIkepili Gamut (TM-30) – Pehea ke kala saturated a desaturated paha (ʻo ka ikaika o nā kala).
Kiʻi vector kala (TM-30) – He aha nā waihoʻoluʻu i saturated/desaturated a inā paha he hoʻololi hue i kekahi o nā pahu waihoʻoluʻu 16.
CQS -ʻO ka ʻĀpana Kūleʻa kala - He ʻokoʻa i nā kala ana CRI unsaturated.He 15 mau kala i hoʻopiha piha ʻia i hoʻohana ʻia no ka hoʻohālikelike ʻana i ka hoʻokae chromatic, ka makemake o ke kanaka, a me ka hana kala.
ʻO wai ke kukui LED ʻoi aku ka maikaʻi no kāu papahana?
Ua hoʻolālā mākou i kā mākou mau ʻāpana LED keʻokeʻo āpau e loaʻa i kahi CRI kiʻekiʻe ma luna o 90 me hoʻokahi wale nō ʻokoʻa (no ka hoʻohana ʻana i ka ʻoihana), ʻo ia hoʻi he hana maikaʻi loa lākou e hoʻolilo i nā kala o nā mea a me nā wahi āu e hoʻomālamalama ai.
Ma ka hopena o nā mea, ua hana mākou i kekahi o nā kukui LED CRI kiʻekiʻe loa no ka poʻe i loaʻa nā kūlana kikoʻī a i ʻole no ke kiʻi, televise, hana lole.Loaʻa i ka UltraBright™ Render Series nā waiwai R kokoke loa, me ka helu R9 kiʻekiʻe.Hiki iā ʻoe ke ʻike ma aneʻi i kā mākou hōʻike photometric a pau kahi e ʻike ai ʻoe i nā waiwai CRI no kā mākou mau paʻi āpau.
Loaʻa kā mākou mau kukui a me nā pahu kukui i nā ʻano o nā ʻōlinolino, nā mahana kala, a me nā lōʻihi.ʻO kā lākou mea maʻamau ka CRI kiʻekiʻe loa (a me CQS, TLCI, TM-30-20).Ma kēlā me kēia ʻaoʻao huahana, e ʻike ʻoe i nā hōʻike photometric e hōʻike ana i kēia mau heluhelu āpau.
Hoʻohālikelike i nā kukui kukui LED CRI kiʻekiʻe
Ma lalo ʻoe e ʻike ai i ka hoʻohālikelike ʻana ma waena o nā kukui (lumens i kēlā me kēia wāwae) o kēlā me kēia huahana.Loaʻa mākou i nā manawa a pau e kōkua iā ʻoe i ke koho ʻana i ka huahana kūpono pū kekahi.
