ʻO ka MediaLight Pro2
He kūlana hou no ka pololei a me ka hōʻoluʻolu

Please e hoailona oukou: Inā ʻaʻole ʻoe he mea pena kala ʻoihana, mea paʻi kiʻi a i ʻole hoʻoponopono wikiō ke ho'āʻo nei paha ʻoe e ʻimi i ka Mk2 Pūnaewele or LX1 ma kahi.

ka Pūnaehana kukui ʻo MediaLight Pro2 Bias ua hana ʻia no nā alakaʻi, nā mea hoʻoponopono, a me nā mea kala e pono ai ka CRI kiʻekiʻe loa a me ka hāʻawi ʻana i ka mana spectral like ʻole i kahi kukui bias no kā lākou hōʻike ʻoihana.

ka Pro2 hoʻohana i kahi papa hou o ColorGrade™ MPro2 SMD (LED) chips, powered by blue-violet emitters e aneane hoʻopau i ka LED emitter spike, me kahi CRI kupaianaha o 99 Ra, TLCI 99.7 Qa, a me Spectral Similarity Index (SSI) o 88. i hoʻokomo pū ʻia me ka dimmer ʻole flicker-free e hana ana ma 30 kHz (30,000 Hz vs 220 Hz no nā mea hoʻomāmā MediaLight ʻē aʻe - a ʻae, kūʻai kaʻawale mākou i nā dimmers no laila hiki iā ʻoe ke hoʻohui iā lākou i kāu hoʻonohonoho e kū nei - akā e ʻoluʻolu ʻoe ʻaʻole pono ʻoe e hoʻohui i kekahi ma aneʻi no ka mea ua hoʻokomo mua ʻia ka dimmer flicker-free).

ʻAʻole hoʻokomo ka Pro2 i kahi mana mamao. Ma kahi o ia, e komo pū ana kā mākou dimmer kīwī ʻole kiʻekiʻe loa. Hiki iā ʻoe ke noi i kahi dimmer mamao e hoʻohui ʻia i kāu kauoha i ʻole ka uku, akā e haʻalele ʻoe i ka hana dimming ʻole flicker-free. Manaʻo mākou e hāʻawi i nā koho mamao i ka wā e hiki mai ana akā, i kēia manawa, ʻoi aku ka SPD a me ka hoʻonā kino ma mua o ka ʻoluʻolu mamao. Inā makemake ʻoe i kahi mamao manuahi a me ka dimmer, e ʻoluʻolu e leka uila iā mākou me kāu ID kauoha a me kāu kumu hōʻike e pale aku ai i ka hoʻopili ʻana i ka infrared me nā mea ʻē aʻe.

Inā ʻaʻole ʻoe i ʻike ma mua o SSI: he hoʻohālikelike ia o kahi kumu kukui me kahi kukui kuhikuhi (ma kēia hihia, D65). Hoʻohālikelike ia i ka hāʻawi mana spectral (SPD) o ke kumu kukui me D65. No ka hoʻohālikelikeʻana,ʻo ka MediaLight Mk2 (CRI 98 Ra) pono loa he SSI o 70. E like me kēia kākauʻana, hāʻawi ka MediaLight Pro2 i ka SSI kiʻekiʻe loa i loaʻa no kahi kumu kukui LED hana.

ʻO ka hapa nui o nā ʻōnaehana kukui LED e hāʻule i ka waiwai R9 (ʻaʻole i hoʻokomo ʻia i ka helu CRI) akā koʻikoʻi no nā ʻili ʻili kūpono a me nā ʻulaʻula hohonu. Hoʻohana pinepine lākou i nā phosphors ʻōmaʻomaʻo ʻoi aku ka liʻiliʻi, hiki ke hopena i ka ʻōmaʻomaʻo ʻōmaʻomaʻo ʻoiai ke kukui ʻana i nā paia hina hina.

Ma waho aʻe o ka ʻenekini photon polū-violet, kahi kokoke e hoʻopau i ka overshoot polū, ka MediaLight Pro2 hoʻohana i kahi hui phosphor kūikawā e hoʻihoʻi i kēia mau ʻulaʻula koʻikoʻi, e hana ana i kahi SPD maʻalahi a ʻoi aku ka māmā maoli.

Eia ka spike emitter no ka MediaLight Pro kumu (pili ka luminance; e nānā i ke ʻano o ka spike ma ka ʻaoʻao hema i ke koena o ka spectrum):

'Ōlelo Aʻo: Makemake maoli kekahi mau mea kūʻai aku i nā huahana makamae loa. ʻOiai mākou e mahalo i kēlā, e ʻoluʻolu e ʻike i kēlā me kēia huahana a mākou e kūʻai aku ai - mai ka $15 LX1 Bias Light a i ka poʻokela MediaLight Pro - ua hōʻoia ʻia no ka pololei. ʻoi aku ka SMPTE, ISF, a me nā kūlana CEDIA.

Aku; DR: Hiki ke hoʻohana 'ia nā mea a pau ma kēia pūnaewele.

No laila, no ke aha e hana ai i nā huahana hou e like me ka MediaLight Pro2?

1) No ka mea, ʻokoʻa ka ʻike ʻike ma waena o nā kānaka a hoʻomaikaʻi me ka ʻike. ʻO ka nui o ka manawa a mākou e hoʻohana ai me ka ʻenehana hōʻike, ʻoi aku ka nui o kā mākou ʻike ʻana i kona ikaika a me nā hemahema.

I ka wā i ʻike mua ʻia ai nā TV 720p a me 1080p, ʻōlelo kekahi poʻe i ka nānā ʻana iā 1080p e like me ka nānā ʻana ma ka puka makani. I kēia manawa, ʻoi aku mākou ma mua o 4K.

2) No ka mea, ke manaʻo nei nā huahana e like me ka MediaLight Pro2 i kahi e loaʻa ai nā kukui ʻoihana i loko o 3-5 mau makahiki, ʻoiai inā ʻaʻole hiki iā mākou ke hoʻokō i ke kumu kūʻai kūʻai nui. E like me ka MediaLight Pro v1 i hoʻomaha i ka Mk2 Series, ʻo kā mākou pahuhopu ka lawe ʻana i nā mea a mākou e aʻo ai mai Pro2 i ke koena o kā mākou laina.

Size pakuhi

No nā hōʻike i ʻoi aku ka nui ma mua o 90″ kahi i makemake ʻia ai nā kukui ʻaoʻao 4, e kau i ke kāʻei 3″ mai ka lihi (ma mua o 2″) e pale i ka holo pōkole ma nā LED a puni nā ʻaoʻao a pau.

E ʻoluʻolu e heluhelu inā e hahai ana i nā kuhikuhi "Hōʻike ma kahi kū":
Ua emi iki ke kumu kūʻai no ka hoʻohana ʻana i kahi ʻāpana pōkole, akā ua hōʻike nā mea hoʻohana i ka "halo" ke nānā aku i ka laha loa ke noho mamao nā kukui mai ka lihi. ʻAʻole kēia e hōʻemi i ka pono, akā hāʻawi i nā koho hoʻonohonoho liʻiliʻi. Loaʻa iā ʻoe ka maʻalahi ke koho ʻana i nā manaʻo ʻaoʻao 3 a i ʻole 4 ʻaoʻao.

Ke hana mau nei ka hoʻonohonoho pōkole no ka 1 m MediaLight Pro2 ma nā hōʻike a hiki i ka 46″ mai ka hui pū ʻana o ka mālamalama mai nā ʻaoʻao i nā pale liʻiliʻi - ʻo ia hoʻi ke kumu e lawa ai nā ʻaoʻao 3 no nā nānā kamepiula.
