Māhele ʻIke LED 2 : He aha nā kala i loaʻa i nā LED?

LED keʻokeʻo

Hana ʻia kekahi mau ʻokoʻa i ka wā o ke kaʻina hana o nā kukui LED i koho ʻia.ʻO nā ʻāpana chromatic i kapa ʻia ʻo 'bin' he mau ʻāpana ʻāʻī ma ka laina BBL.ʻO ka like ʻole o ka waihoʻoluʻu e pili ana i ka ʻike a me nā kūlana maikaʻi o ka mea hana.ʻO kahi koho nui aʻe ke ʻano o ka maikaʻi, akā ʻoi aku ka nui o nā kumukūʻai.

ʻO MacAdam Ellipses

E nānā i ka ʻāpana ma ke kiʻikuhi chromaticity i loaʻa nā waihoʻoluʻu āpau i hiki ʻole ke hoʻokaʻawale ʻia, i ka awelika o ka maka kanaka, mai ke kala i waenakonu o kahi ellipse.Hōʻike ka contour o ka ellipse i ka ʻokoʻa ʻike ʻia o ka chromaticity.Hōʻike ʻo MacAdam i ka ʻokoʻa ma waena o nā kumu kukui ʻelua ma o nā ellipses, i wehewehe ʻia he 'ʻanuʻu' e hōʻike ana i ka ʻokoʻa maʻamau o ke kala.Ma nā noi i ʻike ʻia nā kumu kukui, pono e noʻonoʻo ʻia kēia ʻano no ka mea he haʻahaʻa haʻahaʻa ka waihoʻoluʻu o ka ellipse 3-step ma mua o ka 5-step.

Nā LED kala

Hoʻokumu ʻia ke kiʻi chromatic CIE ma luna o ke ʻano physiological o ka maka o ke kanaka e nānā i nā kala ma o ka wāwahi ʻana i ʻekolu mau ʻāpana chromatic kumu (ʻekolu kala kala): ʻulaʻula, uliuli a me ka ʻōmaʻomaʻo, i hoʻonoho ʻia ma ka piko o ka pihi kiʻi.Hiki ke loaʻa ke kiʻi chromatic CIE ma ka helu ʻana i ka x a me ka y no kēlā me kēia kala maʻemaʻe.Hiki ke ʻike ʻia nā kala kikoʻī (a i ʻole nā ​​kala maʻemaʻe) ma ka ʻaoʻao kuhi, aʻo nā kala i loko o ke kiʻikuhi he mau kala maoli.Pono e hoʻomaopopo ʻia ʻo ka waihoʻoluʻu keʻokeʻo (a me nā kala ʻē aʻe i ke kikowaena waena - nā kala achromatic a i ʻole nā ​​kala hina) ʻaʻole nā ​​kala maʻemaʻe, a ʻaʻole hiki ke hoʻopili ʻia i kahi lōʻihi nalu.
