I nā makahiki i hala iho nei, me ka hoʻohana nui ʻana o ka solid-stateNā kukui kukui LED, He nui ka poʻe e ho'āʻo nei e nānā i ka paʻakikī a me nā ʻano kaohi o ka ʻenehana kala LED.

E pili ana i ka hui hoʻohui

Nā kukui uilae hoʻohana i nā kumu kukui he nui e loaʻa i nā kala like ʻole a me ka ikaika.No ka ʻoihana kukui ʻoliʻoli, ʻo ka hoʻohui ʻana a me ka hui ʻana i nā kala he clich é.No nā makahiki he nui, ua hoʻohana nā mea hoʻomaʻamaʻa i nā kukui me nā kānana kala e hoʻolālā i ka ʻāpana like ma ka canopy, ʻaʻole maʻalahi ke kāohi.ʻO kahi kukui me ʻekolu kumu kukui MR16, kēlā me kēia me nā kānana ʻulaʻula, ʻōmaʻomaʻo, a polū.I nā lā mua, ʻekolu wale nō kaila mana DMX512 o kēia ʻano kukui a ʻaʻohe ala hoʻokele ikaika kūʻokoʻa.No laila paʻakikī ka mālama ʻana i ka waihoʻoluʻu ʻaʻole i hoʻololi ʻia i ka wā o ka dimming.ʻO ka mea maʻamau, hoʻonohonoho nā polokalamu uila uila i kahi "hoʻololi kala ʻana i ke kukui" e hoʻopau maʻalahi i nā kukui.ʻOiaʻiʻo, aia nā ala maikaʻi aʻe, ʻaʻole wau e papa inoa iā lākou āpau ma aneʻi.

Ka Mana a me ka wehewehe o na kala

Inā ʻaʻole hoʻohana ka mea hoʻohana i nā waiwai DMA maʻemaʻe no ka hoʻomalu ʻana i nā kukui uila naʻauao, akā hoʻohana i kekahi ʻano mana abstract, hiki ke hoʻohana ʻia kahi waiwai ikaika virtual.ʻOiai inā ʻōlelo ka mea hana i ka hoʻohana ʻana o nā kukui kukui i ʻekolu mau kaha DMA, hiki ke hāʻawi ʻia ke ʻano hoʻokele abstract i ʻehā mau lima e hoʻomalu ai: ka waiwai ikaika a me nā ʻāpana kala ʻekolu.

ʻEkolu mau ʻāpana kala "ma kahi o ka ʻulaʻula, ka ʻōmaʻomaʻo, a me ka uliuli, ʻoiai ʻo RGB kahi ala e wehewehe ai i nā kala.ʻO kahi ʻano ʻē aʻe e wehewehe ai ʻo ia ka hue, saturation, a me ka luminance HSL (kapa kekahi iā ia he ikaika a māmā paha, ma mua o ka ʻōlinolino).ʻO kekahi wehewehe ʻana he hue, saturation, a me ka waiwai HSV.ʻO ka waiwai, i ʻike ʻia he kukui, ua like ia me Luminance.Eia naʻe, aia kahi ʻokoʻa nui i ka wehewehe ʻana o ka saturation ma waena o HSL a me HSV.No ka maʻalahi, ma kēia ʻatikala, wehewehe ka mea kākau i ka hue e like me ke kala a me ka saturation e like me ka nui o ke kala.Inā hoʻonoho ʻia ʻo 'L' i 100%, he keʻokeʻo, 0% ʻeleʻele, a ʻo 50% o L he kala maʻemaʻe me ka saturation o 100%.No 'V', 'ele'ele 'o O% a pa'a 'o 100%, a pono e ho'onui ka waiwai o ka saturation i ka 'oko'a.

ʻO ke ʻano wehewehe ʻokoʻa ʻē aʻe ʻo CMY, ʻo ia kahi ʻōnaehana waihoʻoluʻu ʻekolu e hoʻohana ana i ka hui kala subtractive.Inā hoʻopuka mua ʻia ke kukui keʻokeʻo, a laila hiki ke hoʻohana ʻia nā kānana kala ʻelua e loaʻa ai ka ʻulaʻula: magenta a me ka melemele;Hoʻokaʻawale lākou i nā mea ʻōmaʻomaʻo a me ka uliuli mai ke kukui keʻokeʻo.ʻO ka maʻamau,Nā kukui hoʻololi kala LEDmai hoʻohana i ka hui ʻana kala subtractive, akā he ala maikaʻi kēia e wehewehe ai i nā kala.

Ma ke kumumanaʻo, i ka wā e hoʻomalu ai i nā LED, pono e hiki ke hoʻololi i ka ikaika a me RGB, CMY Hoʻokahi o HSL a i ʻole HSV (me kekahi mau ʻokoʻa ma waena o lākou).

E pili ana i ka hui ʻana o nā kala LED

Hiki i ka maka kanaka ke ʻike i ka mālamalama me nā lōʻihi hawewe mai 390 nm a 700 nm.Ua ho'ohana 'ia ka 'ula'ula (ma kahi o 630 nm), 'ōma'oma'o (ma kahi o 540 nm), a me ka uliuli (ma kahi o 470 nm).ʻAʻole hiki ke hui ʻia kēia mau kala ʻekolu e hana i kēlā me kēia kala i ʻike ʻia e ka maka kanaka
