ʻO Amrit S.

Aloha Amrit.

Mahalo no kāu leka a e ʻoluʻolu e kala i ka pane lohi. Loaʻa pinepine mākou i kēlā nīnau. Pane mau wau me kahi nīnau naʻu iho:

Ke mālama nei ʻoe i ke kālā inā kūʻai ʻoe i kahi huahana i hana ʻole i ka mea i manaʻo ʻia e hana?

Hana mākou i nā kukui bias haʻahaʻa i kumu kūʻai like ʻia me Lumadoodle, ʻoiai ke hāʻawi nei i ka ʻoihana pae kiʻekiʻe, palapala hoʻokō lōʻihi a me nā koho pili hou aku. 

No laila, inā ʻoe e ʻimi e hana i kahi hoʻohālikelike kūpono aʻe, hoʻohālikelike wau iā Lumadoodle i ka mea hou LX1 Bias Kauila mai ka hui MediaLight like.

ʻOi aku ka nui o ka hana ʻana i ke kukui kū pono ma mua o ka lawe ʻana i ka CRI haʻahaʻa (75 Ra wale nō) e hoʻomoana i kahi ʻāpana LED, "e hemo ana i ka pahu ea a hoʻokau i kahi pepili ma hope. e like me kā Lumadoodle makemake iā ʻoe e manaʻoʻiʻo.

Inā ʻaʻole ʻoe makemake e hopena maikaʻi ʻole i ke kiʻi TV, a laila aia nā pae no CRI (Index Rendering Index), chromaticity a me ka mana spectral mana o ka malamalama ambient e pono e ukali ʻia. 

Ua hala he XNUMX mau makahiki o kā mākou hui i ka hoʻomaikaʻi ʻana i ka pololei a me nā hiʻohiʻona o kā mākou huahana ʻoiai ʻaʻole hoʻomaikaʻi iki kā lākou, a ʻike mākou he wahi koe no ka hoʻomaikaʻi, ʻo ia ke kumu e hana mau nei mākou i ka ʻike hou. ʻO kēia ke kumu e hoʻohana ʻia ai nā huahana MediaLight e nā poʻe loea wikiō ma ka ʻaneʻane i kēlā me kēia keʻena a me nā hale hana i hope. 

Hele me ka ʻōlelo ʻole, akā ʻaʻole pili iki mākou iā Lumadoodle, Govee, Antec, Zabiki a i ʻole nā ​​mea ʻē aʻe .. Eia naʻe, ʻo ka mea e ukali nei e pale i ka manaʻo a kālele ana i ka ʻike spectrophotometric a me ka hoʻolālā kino. 

Akā, hoʻi i kāu nīnau. Makemake wau e hiki ke hoʻouna i kahi pane luhi me maoli ʻikepili, no laila ua kauoha wale wau i kahi anakuhi Lumadoodle hou a ana iā ia ma lalo o Sekonic C7000.

ʻO ka mea mua, e lawe kāua i nā ʻāpana mai kā lākou puʻukana a nānā i ka Lumadoodle e pili ana i kahi MediaLight. ʻO ka mea mua āu e ʻike ai he nui aku nā LED o MediaLight. Loaʻa i kahi kahakai 5m Lumadoodle 90 LED. Loaʻa i kahi MediaLight o ka lōʻihi like me 150 LEDs. Aia he 66.66% mau LED hou ma ka MediaLight i kēlā me kēia mika. 

Ke hoʻohālikelike nei iā Lumadoodle a me MediaLight 
ʻO Density LED

 

ʻOi aku ka uku o nā ʻāpana ma MediaLight i ka 66% hou aʻe ma muli o ka nui o ka LED a ʻoi aku ka haʻahaʻa, ʻoi aku ka nui o ka ʻoiaʻiʻo ʻo SMD chips i hana ʻia. ʻO ka ʻoiaʻiʻo, kumukūʻai lākou ma ka liʻiliʻi 20 mau manawa hou aʻe no LED. 

Ke hoʻohālikelike nei i ke kukui uila LED maikaʻi

ʻO ka mea mua, e ʻōlelo wale wau ʻaʻole kēia he hoʻohālikelike ʻana i nā ʻāpala.

Hoʻolālā ʻia ʻo MediaLight e nā kiʻi ʻepekema imaging a ʻAʻole ʻo Lumadoodle. Aia i loko o MediaLight nā ʻāpana kala Mk2 Customgrade a ʻaʻole Lumadoodle i hana. ʻAʻole ia e kīkēkē i ka poʻe e hana ana ma laila, ʻoiai he poʻe maikaʻi loa lākou, ʻaʻole lākou e noʻonoʻo i ke ʻano o ke kiʻi i ke kūkulu ʻana i kā lākou huahana a ʻoiaʻiʻo loa e pili ana iā ia. Makemake mākou i kēia i nā ʻoihana e kūʻai aku nei i nā LED haʻahaʻa akā e ʻōlelo ana he pololei. 

Ua hoʻāʻo wau i kahi Lumadoodle i kekahi mau makahiki i hala aku nei a ua manaʻo wau, e like me ka nui o nā ʻenehana, inā he hoʻomaikaʻi hoʻonui ʻia mai ia manawa. I ka ʻoiaʻiʻo, ua haʻahaʻa loa ka CRI (index rendering index) ʻoiai ua holomua nui ka ʻenehana LED i nā makahiki he 5 i hala.

Lumadoodle Waihoʻoluʻu Rendering Index (CRI) = 76.3 Ra (hemahema)
ʻO ka Index Index Rendering MediaLight (CRI) ≥ 98 Ra 

No ka hoʻohālikelike, ʻo ka hōʻike mua (post-beta test) ʻo MediaLight i kūʻai ʻia ma 2015 i kahi CRI o 91 (i kēia manawa 98-99 Ra). Akā, ʻo ka MediaLight o 2015 kahi CRI kiʻekiʻe loa ma mua o ka Lumadoodle o kēia lā.

Ua ana ka hahana hou i ka mehana ma mua o ke kaha o mua, kahi e hiki ai iā ʻoe ke ʻike i kaʻu mau ana ʻana ma aneʻi mai ka 2017, Eia naʻe ke kūpono kokoke i kā lākou hoʻolaha CCT o 6000K (e kūlike ana me ke ana hoʻohālikelike 6500K). 

He aha kaʻu manaʻo ke kūpono kokoke?

ʻO ka honua o ka mālamalama bias ka Wild West. Aia nā kūlana ʻoi loa o ka ʻoihana, akā he mea kakaikahi paha ka mea e ukali nei iā lākou.

Waiho mākou i kā mākou huahana no ka hōʻoia kūʻokoʻa e ISF, ʻoiai ka hapa nui o nā ʻoihana e paʻi maʻalahi i ka "6500K" ma ka pūʻolo, a i ʻole "keʻokeʻo keʻokeʻo", a i ʻole "keʻokeʻo maoli." Ua kūʻai aku au i hoʻokahi no ka hoʻāʻo ʻana i ʻōlelo "keʻokeʻo hauʻoli" ma ka pūʻolo. 😁

ʻO nā lawehala ʻelua ʻoi loa, ʻo Vansky lāua ʻo Antec. Nui ʻino lākou a ʻeha maoli lākou i ka hoʻohana ʻana iā lākou. Inā ʻoe i hele wāwae i kahi alapiʻi a i ʻole ka papa kaʻa kau me nā kukui ʻino, ʻino, ʻike ʻoe i kaʻu e ʻōlelo nei. 

Nā kukui Biasky Vansky i koi i kahi anuanu kala o 6500K ma kā lākou pūnaewele akā ana ʻia ma kahi o 20,000K

ʻO Antec Bias Lighting 'ōlelo lākou ua "hoʻonohonoho pololei' ia ko lākou mau kukui i 6500K" ma kā lākou pūnaewele akā lākou ana ʻia ma 54,000K.  ʻAʻole lākou e hele i ka sugarcoat, weliweli lākou. 

Ke hoʻopuni nei i kēia hoʻolauna, Zabiki a Halo Bias Uila ʻino loa hoʻi i kā lākou kuleana ponoʻī, akā, me ka mea pōmaikaʻi, ua hele lākou i waho o ka ʻoihana, no laila ʻaʻole pono wau e loiloi hou iā lākou.

No laila, ʻo ka pane pōkole ʻoi aku ke kumukūʻai o ke kūkulu hou ʻana i MediaLight ma muli o ka nui o nā LED, ʻo lākou iho ke kiʻekiʻe kiʻekiʻe - kūkulu ʻia e noi ana i nā "kūmole kūmole," a me kahi pūpū o nā mea ʻē aʻe e pono ai ʻoe e hana i kahi LED alakai i ʻO ke kukui kūpana piha piha:

• CRI o -98 ma kahi o 76 (nā kukui uila he palena palena iki o 90)
• Hoʻolālā i nā ʻae ʻoihana binning (ma waena o 50K o 6500K)
• Ieoaeunoaa PCB keleawe
• Nui nā keu e pono ai ʻoe e kūʻai ʻokoʻa me nā kukui ʻē aʻe (Ie ʻālohilohi a Mamao, Ho'oponopono, on / off toggle, extension extension, wire routing clips). 
• Ua ʻōlelo au i 66.66% hou aku nā LED i kēlā me kēia pā?

I 'ōlelo e komo koke wau i ka ʻikepili photometric maka. Akā ma mua o kaʻu hana ʻana, aia nō, hoʻokahi mahele huikau o ka inoa ʻo Lumadoodle e hoʻohoka nui ai, a ʻo ka hopena e nui nā leka uila a me nā kamaʻilio pūnaewele ʻana iaʻu. 

ʻAʻole wau i hoʻāʻo i ka Lumadoodle Pro no ka mea inā hauʻoli lākou i ka paʻi ʻana i kahi kikoʻī i ʻoi aku ka maikaʻi ma mua o ko lākou mau kukui keʻokeʻo, ua lawa kēlā iaʻu. Eia naʻe, inā ʻoe e aʻo i hoʻokahi wale nō mea mai kēia leka uila: "mai ka hoʻoliʻiliʻi ʻana i nā kukui bias a me ka acuity o ke kala mai hui.

Hoʻohālikelike ʻia nā ʻāpana MediaLight āpau me D65 keʻokeʻo. ʻAʻole lākou e hoʻololi i nā kala.

Ke hoʻohālikelike nei i nā hiʻohiʻona MediaLight a me Lumadoodle

• Pākuʻi ʻia ʻo MediaLight i kahi dimmer. ʻAʻole hoʻokomo ʻo Lumadoodle i kahi dimmer no kā lākou hiʻohiʻona keʻokeʻo (pono ke keʻokeʻo bias ʻo D65 keʻokeʻo, no laila ʻo kēia kā mākou e hoʻohālikelike nei), akā hiki iā ʻoe ke kūʻai i hoʻokahi no ka $ 12 paha.
• Pākuʻi ʻia ʻo MediaLight i kahi hoʻololi kuapo / pio. ʻAʻole Lumadoodle. Inā ʻaʻole pio ka port USB ma kāu kīwī me ke kīwī, kauoha ʻia ʻoe e unplug ia. 
• Hana ka dimmer a me nā hana mamao a MediaLight me nā mamao mamao Harmony a i ʻole IR unotes, ʻaʻole i hoʻopili ʻia ʻo Lumadoodle i kahi dimmer a ʻo ka uniona i loaʻa no ke kūʻai aku ʻaʻole Harmony a i ʻole IR unuhi mamao maʻalahi.

• Pākuʻi ʻia ʻo MediaLight i kahi palapala hoʻokō 5 mau makahiki, a ʻo ka palapala hoʻokō Lumadoodle he 1 makahiki.
• ʻAʻole hoʻololi ʻo MediaLight i nā kala a hana ʻo Lumadoodle i kahi hoʻohālikelike me nā kala ʻokoʻa. Inā makemake ʻoe e hoʻololi i nā kala, ʻo Lumadoodle kahi koho maikaʻi aʻe. Eia nō naʻe, ʻino nā loli hoʻololi kala i ke kiʻi ma ka pakuhi no ka nānā ʻana i ke kala. ʻO ka hopena, ʻaʻole hāʻawi ʻo MediaLight iā lākou. 
• Ua hōʻoia ʻia ʻo MediaLight no ka pololei e ka Imaging Science Foundation a hoʻolālā ʻia e ʻoi aku ma mua o nā kūlana SMPTE no ka mālamalama e pili ana no nā kaiapuni wikiō koʻikoʻi. Pili kokoke ʻo Lumadoodle i ko lakou i hōʻike ʻia nā māka o 6000K a me 76 Ra, akā ʻaʻole kēia nā pae kuhikuhi.

Nā hiʻohiʻona kauila

• Hoʻohālikelike ʻia nā LED MediaLight me D65 (6500K me ka Δuv o .003 - ka Δuv o ka hoʻomālamalama o ka lā, i ka laina me ka standard CIE illuminant D65) me ka index index rendering (CRI) ʻoi loa o ≥ 98 Ra. ʻO nā kaulike chromaticity kahi kokoke loa i ka x = 0.3127, y = 0.329 maʻamau.
