Nā huahana kukui LED CRI kiʻekiʻe
Nui aʻe nā mea e noʻonoʻo ai i ke kūʻai ʻana i nā huahana kukui LED ma mua o nā ʻōpuʻu incandescent, ʻoi aku hoʻi inā ʻo ka ʻenehana wale nō ka ʻenehana i ka mākeke. ʻO kekahi o kēia mau kumu ke ana o nā huahana kukui LED CRI kiʻekiʻe.
I. He aha ka CRI i ke kukui LED?
Nui nā kikoʻī e kau i ka manaʻo koʻikoʻi i ka ʻōlelo kuhikuhi kala (CRI), kahi e ana i ka hiki o ka mālamalama e hoʻopuka pololei i nā kala a e like me nā kala maoli o ka lā. Ke ʻoi aku ka nui o ka CRI o ke kukui LED ma mua o 90, ua manaʻo ʻia he LED CRI kiʻekiʻe.
Ua helu ʻia ʻo CRI ma ke ʻano he waiwai me ka helu kiʻekiʻe loa o 100. ʻO ka helu CRI ʻoi aku ka nui ma mua o 90, ʻo ia ka mea e hoʻohālikelike ke kumu kukui i ka mea i like loa me ke ʻano ma lalo o nā kumu kukui kūlohelohe. ʻO nā huahana kukui LED CRI kiʻekiʻe e hōʻike i nā kala saturated ma mua o nā huahana ma lalo o 90 CRI, a makemake nui ʻia e nā ʻenehana kamera he nui i nā hanana TV a me nā lekiō, ka poʻe i manaʻoʻiʻo ʻo ke kukui LED CRI kiʻekiʻe ka ʻoi aku ka kiʻekiʻe a me ka holomua o nā kukui haʻuki LED i kēia lā.
I mea e ʻike ai i ka ʻokoʻa ma waena o nā pae like ʻole o CRI, hiki iā ʻoe ke kuhikuhi i ke kiʻi ma lalo nei.
II. He aha ka pilina ma waena o CRI a me Lumen i ke kukui LED?
E like me kāu e ʻike ai, ʻoi aku ka ʻoi aʻe o nā kani o ka CRI i ke kiʻi ma luna. Eia naʻe, hiki mai ka vividness a me ka maʻemaʻe i ke kumu kūʻai. ʻO ke kiʻekiʻe o ka CRI, ʻoi aku ka wikiwiki o ka hāʻule ʻana o ka lumen mai ka puka kukui LED. No ka hāʻawi ʻana iā ʻoe i nā kikoʻī hou aku, eia nā hōʻemi lumen āu e makemake ai e ʻike i ka hāʻule ʻana o ka lumen i hoʻohālikelike ʻia me ka CRI 70 maʻamau:
CRI 80 -> -10%
CRI 85 -> -15%
CRI 90 -> -20%
CRI 95 -> -25%
No laila, inā makemake kāu pāʻani pāʻani a i ʻole ʻoihana ʻoihana iā CRI95, e kūʻai ʻoe i 20% o ka mana hou e mālama i nā pae lumen maʻamau a mālama i ka hoʻomālamalama ʻāina i helu ʻia.
III. ʻEhia ke kumukūʻai no ka loaʻa ʻana o kahi kukui CRI kiʻekiʻe?
No nā liona kiʻekiʻe loa a i ʻole nā kahua pāʻani ma ka wikiō HD TV a i ʻole 4K hoʻolaha, koi ʻia nā LED CRI kiʻekiʻe mai 90 a i 95. Eia naʻe, i ka hapanui o nā hihia, ʻaʻole i hoʻohana mau ʻia nā mea hoʻonaninani hāmeʻa CRI LED kiʻekiʻe no nā pāʻani pae maʻamau, ʻoiai ma he pae lux awelika ma ka honua ma kahi o 800 lux.
No laila, inā ponoʻoe e hoʻohana i nā kukui kukui CRI kiʻekiʻe no kāu papahana,ʻo ke kumukūʻai kukui CRI kiʻekiʻe e pili ana i ka mana o nā kukui LED a me ka helu o nā kukui LED āu i hoʻohana ai i ka papahana. Welina mai e kūkākūkā me OAK LED Inā makemake ʻoe i kahi hoʻolālā kumukūʻai i manaʻo ʻia no nā kukui kukui LED CRI kiʻekiʻe.
