IMediaLight vs.Lumadoodle: Umehluko Osemqoka

MediaLight Ethandekayo:

Ngisanda kuthola iwebhusayithi yakho. Ngivela eLumadoodle engayilimaza lapho ngithuthela efulethini elisha. Ngabe sikhona isizathu esenza ukuthi amalambu akho abize kakhulu? Ungathanda ukungikhombisa idatha yangempela?

U-Amrit S.

Sawubona Amrit.

Siyabonga ngomyalezo wakho futhi ngicela uthethelele impendulo ebambezelekile. Lowo mbuzo siwuthola kakhulu. Imvamisa ngiphendula ngombuzo wami:

Ngabe uyonga imali uma uthenga umkhiqizo ongakwenzi okufanele ukwenze?

Senza izibani zokuchema ezingabizi kakhulu ezibiza cishe ngokufana neLumadoodle, ngenkathi sinikela ngokunemba kwezinga lobuchwepheshe, iwaranti ende nezinketho zokuxhuma eziningi. 

Ngakho-ke, uma ufuna ukwenza ukuqhathanisa okufanelekile, ngingaqhathanisa iLumadoodle ne sha sha Ukukhanyisa kwe-LX1 Bias kusuka eqenjini elifanayo leMediaLight.

Kuningi kakhulu okwenza ukukhanya okunokwenzelela okunembile kunokuthatha umugqa we-LED ophansi we-CRI (kuphela ama-Ra angu-75), “ukukhipha ishubhu lepulasitiki bese ubeka isitika ngemuva,” njengoba iLumadoodle ingathanda ukuthi ukholwe.

Uma ungafuni ukuba nomthelela omubi esithombeni se-TV, khona-ke kunamazinga we-CRI (i-Colour Rendering Index), i-chromaticity nokwabiwa kwamandla we-spectral wokukhanya kokukhanya okufanele kulandelwe. 

Inkampani yethu isichithe iminyaka eyisikhombisa ithuthukisa ukunemba kanye nezici zemikhiqizo yethu ngenkathi eyazo ingakathuthuki nhlobo, futhi siyazi ukuthi kusekhona isikhala sokwenza ngcono, yingakho sihlala sisebenza ku-iteration elandelayo. Kungakho imikhiqizo yeMediaLight isetshenziswa ngabasebenza ngamavidiyo cishe kuzo zonke izikhungo ze-studio nezokukhiqiza okuthunyelwe. 

Akusho, kepha asihlangene neze neLumadoodle, Govee, Antec, Zabiki noma omunye umuntu .. Kodwa-ke, okulandelayo kugwema umbono futhi kugxile kudatha ye-spectrophotometric nokwakhiwa komzimba. 

Kepha, buyela embuzweni wakho. Bengifuna ukwazi ukuthumela impendulo ephelele nge okwangempela idatha, ngakho-ke ngivele ngayalela iyunithi entsha yeLumadoodle ngayilinganisa ngaphansi kwe-Sekonic C7000.

Okokuqala, ake sikhiphe imichilo emaphaketheni abo bese sibheka iLumadoodle eseduze neMediaLight. Into yokuqala ozoyibona ukuthi iMediaLight inama-LED amaningi. Umugqa we-5m Lumadoodle unama-LED angama-90. IMediaLight enobude obufanayo inama-LED ayi-150. Kunama-LED amaningi angama-66.66% kwiMediaLight ngemitha ngalinye. 

Ukuqhathanisa iLumadoodle neMediaLight 
Ubuningi be-LED

 

Amachips akwiMediaLight angabiza u-66% ngaphezulu ngokususelwa kunani le-LED kuphela noma ngabe isivuno esincane, ukunemba okuphezulu kwama-SMD chips akubizi kakhulu ukukhiqiza. Iqiniso ukuthi, zibiza okungenani Izikhathi ezingama-20 ngaphezulu kwe-LED ngayinye. 

Ukuqhathanisa ukukhanya kwe-LED ekhanyayo

Okokuqala, mangisho nje ukuthi lokhu akusikho ukuqhathanisa kwama-apula nama-aphula.

IMediaLight yakhelwe ngabachwepheshe besayensi yezithombe futhi ILumadoodle ayiyona. IMediaLight iqukethe ama-chips we-Colourgrade Mk2 ngokwezifiso kanti iLumadoodle ayinayo. Lokho akukhona ukungqongqoza abantu abasebenza lapho, njengoba bengabantu abahle kakhulu, ababheki nje ikhwalithi yesithombe lapho besakha imikhiqizo yabo futhi bathembeke kakhulu ngakho. Sikhetha lokhu kunezinkampani nazo ezidayisa ama-LED asezingeni eliphansi kodwa athi anembile. 

Ngivivinye iLumadoodle eminyakeni embalwa edlule futhi ngacabanga, njengobuchwepheshe obuningi, ukuthi bekuzoba nokuthuthuka okwengeziwe kusukela lapho. Empeleni, i-CRI (inkomba yokunikeza umbala) isephansi kakhulu yize ubuchwepheshe be-LED buthuthuke kakhulu eminyakeni emihlanu edlule.

I-Lumadoodle Colour Rendering Index (CRI) = 76.3 Ra (kuncane)
I-MediaLight Colour Rendering Index (CRI) ≥ 98 Ra 

Ngokuphambene, okokuqala (ukuhlolwa kwe-post-beta) iMediaLight edayiswe ngo-2015 kwaveza i-CRI engu-91 (manje eyi-98-99 Ra). Kepha, neMediaLight ka-2015 yayine-CRI ephakeme kakhulu kuneLumadoodle yanamuhla.

Umugqa omusha ulinganise ukufudumala kunomugqa wangaphambilini, ongazibona izilinganiso zami lapha kusuka ku-2017, kodwa noma kunjalo ngokuzwakalayo eduze kwe-CCT yabo ekhangisiwe ye-6000K (ngokuqhathaniswa ne-standard standard ye-6500K). 

Ngiqonde ukuthini ngokuzwakalayo vala?

Umhlaba wokukhanyisa okweqile yiWild West. Kunamazinga embonini aqinile impela, kepha bambalwa ababonakala bewalandela.

Sithumela imikhiqizo yethu ukuthola isitifiketi esizimele yi-ISF, ngenkathi izinkampani eziningi zimane ziphrinte u- "6500K" kwiphakethe, noma "umhlophe omsulwa", noma "umhlophe weqiniso." Ngake ngathenga eyodwa ukuze ngivivinye ethi "happy white" ephaketheni. 😁

Ababili abaphula umthetho kakhulu, yize kwakunguVansky no-Antec. Zazimbi kangangokuba zazilimaza empeleni ukuzisebenzisa. Uma wake wahamba ezitebhisini noma emphemeni wokupaka ngamalambu ahlasele, anokhahlo, uyazi ukuthi ngiqonde ukuthini. 

Izibani zeVansky Bias ifune ukushisa kombala kwe-6500K kuwebhusayithi yabo kodwa kulinganiswe cishe i-20,000K

Ukukhanyisa kwe-Antec Bias bathi amalambu abo "alinganiswe kahle afinyelela ku-6500K" kwiwebhusayithi yabo kepha bona kulinganiswe ku-54,000K.  Ukungayi koshukela, babesabeka. 

Ukuhlanganisa lesi sethulo, Zabiki futhi Ukukhanyisa kwe-Halo Bias nabo babenobuhlanya kakhulu, kepha, ngenhlanhla, base bephumile ebhizinisini, ngakho-ke akusadingeki ukuthi ngibuye ngizibuyekeze.

Ngakho-ke, impendulo emfushane ukuthi kubiza imali ethe xaxa ukwakha iMediaLight ngenxa yokuthi kunama-LED amaningi, wona uqobo ayikhwalithi ephezulu - akhelwe ukufuna "amazinga ezethenjwa," kanye nenqwaba yezinye izinto odinga ukuzenza i-LED strip ukukhanya okusebenza ngokugcwele:

  • I-CRI engu-≥98 esikhundleni se-76 (izibani zokuchema kufanele zibe ubuncane obungu-90)
  • Ukubekezelelana okuqinile kwe-binning (ngaphakathi kwe-50K ye-6500K)
  • Ukwakhiwa kwe-PCB yethusi ehlanzekile
  • Kuningi okungeziwe ongakudinga ukukuthenga ngokuhlukile namanye amalambu (Ie ukuncipha futhi kude, I-adapter, ukuvula / ukuvala ukuguquguqula, intambo yokwelula, iziqeshana zomzila wocingo). 
  • Ngabe ngikhulume ngama-LED amaningi angama-66.66% ngomugqa ngamunye?

I isithembiso ukuthi ngizongena kudatha ye-photometric eluhlaza maduzane. Kodwa ngaphambi kokuba ngikwenze, kukhona, ingxenye eyodwa edidayo yokubeka uphawu lwe-Lumadoodle edala ukudideka okuningi, futhi okuholela kuma-imeyili amaningi nasezingxoxweni zewebhu kimi. 

Angizange ngiyivivinye i-Lumadoodle Pro ngoba uma bejabule ukushicilela i-spec ebi kakhulu kunamalambu abo amhlophe, lokho kungifanele. Noma kunjalo, uma ufunda into eyodwa kuphela kule imeyili: "izibani ezishintsha umbala nokukhanya kombala azihlangani.

Yonke imichilo yeMediaLight yenziwe emhlophe i-D65. Azishintshi imibala. 

Ngakho-ke, ukuqhathanisa kwethu kuphakathi kweMediaLight Mk2 neLumadoodle emhlophe.

Nayi idatha eluhlaza kufomethi ye-.csv yezilinganiso ezivela kuzo zombili izingcezu zokukhanya ezithathwe nge-Sekonic C7000 ekhadini elimpunga elingu-18% egumbini elipendwe ngopende kaMunsell N8. (Kungenzeka wake wayibona indawo yethu yokuhlanganisa amanye amakhasi. Sisebenzisa lokho ukuhlola ama-LED, ama-bulb kanye namakhanda wamalambu angawodwa, hhayi amapheshana ahlanganisiwe).

Izilinganiso ezingenhla zithathwe ngobude be-1m bemichilo ye-LED. 

Ukuqhathanisa Izici zeMediaLight neLumadoodle

  • IMediaLight ifaka ne-dimmer. I-Lumadoodle ayifaki i-dimmer yemodeli yazo emhlophe (ukukhanya kwe-bias kufanele kube mhlophe nge-D65, ngakho-ke yilokhu esikufanisa), kepha ungathenga okukodwa cishe u- $ 12
  • IMediaLight ifaka iswishi yokuvula / yokuvala. ILumadoodle ayikwenzi. Uma imbobo ye-USB eku-TV yakho ingacimi ne-TV, uyalelwa ukuthi uyikhiphe. 
  • I-dimmer ne-MediaLight's dimmer kanye neremote isebenza nge-Harmony remote noma i-IR universal remotes, i-Lumadoodle ayifaki i-dimmer futhi iyunithi etholakalayo ukuthengiswa akuyona iHarmony noma i-IR universal remote ehambisanayo. 
  • IMediaLight isebenzisa ithusi elihlanzekile le-PCB (ingxube ye-alloy) ekusebenzeni okuphezulu namakhono okusika ukushisa, iLumadoodle ayisebenzi.
  • IMediaLight ifaka i-adaptha (eNyakatho Melika kuphela), iLumadoodle ayifuni. 
  • IMediaLight ifaka iwaranti yeminyaka emihlanu, kanti iwaranti yeLumadoodle ingunyaka ongu-5.
  • IMediaLight ayishintshi imibala kanti iLumadoodle iyayenza imodeli enemibala ehlukene. Uma ufuna ukushintsha imibala, iLumadoodle inketho engcono. Kodwa-ke, amalambu aguqula umbala athinta kabi isithombe esikrinini ekubukeni okubucayi kombala. Ngenxa yalokho, iMediaLight ayizinikeli. 
  • IMediaLight iqinisekiswe ngokunemba yi-Imaging Science Foundation futhi yakhelwe ukweqa SMPTE amazinga wokukhanya okuzungezile kwezindawo ezibucayi zombala. ILumadoodle isondele ngokunengqondo kubo kusho izinhloso ka-6000K no-76 Ra, kepha lawa awewona amazinga wokukhomba.

Izici Zokukhanyisa

    • Ama-LED e-MediaLight ayenziwa nge-D65 (6500K nge-Δuv ye .003 - the I-ofuv yelanga elakhiwe kabusha, ngokuhambisana ne-CIE ejwayelekile ekhanyayo i-D65) ene-ultra-high color rendering index (CRI) ye- of 98 Ra. Ukuxhumanisa kwe-chromaticity kusondele ngokuphawulekayo ku-x = 0.3127, y = 0.329 standard.

    • ILumadoodle ikhangisa ngokushisa okuncane okungama-6000K (kwamanye amakhasi) futhi izilinganiso zethu ziyakufakazela lokhu. Afudumele kune-6500K (cishe ama-5600K wale sampula). Inkomba yokunikezwa kombala kaLumadoodle ingaphansi kwe- Kunconyelwe i-SMPTE inani eliphansi lika-90 Ra.
Ukukhuluma ngenhloso, izibani eziphakeme ze-CRI zinembe ngokwengeziwe kunezibani eziphansi ze-CRI, kanti ezingama-76 zingaphansi kombundu wokukhiqizwa kabusha kwezithombe okunembile.  
    • IMediaLight inenani elingu-R9 (elibomvu ngokujulile) elingu- ≥ 97. ILumadoodle inenani elingu-R9 elibi. Lokhu kusho ukuthi i-Lumadoodle ayinabo obomvu obujulile kububanzi bayo, okungenani ayihlobene neminye imibala ku-spectrum.
      • Ukukhanya okujulile okubomvu (R9) kubalulekile kumathoni wesikhumba anembile ngenxa yokugeleza kwegazi ngaphansi kwesikhumba sethu. (Lokhu kubalulekile ngisho nangokubonisa okudlulisayo, noma ngabe umthelela ushintshiwe). Ibuye ichaze ukuthi kungani amalambu evamise ukuba nohlobo oluhlaza / oluhlaza okwesibhakabhaka uma kuqhathaniswa namalambu aphezulu e-CRI. Ukukhanya kuqukethe iziqongo eziluhlaza okwesibhakabhaka nokuphuzi.

      Ukusatshalaliswa kwamandla weSpectral ne-CRI yeMediaLight Mk2

      Ukusatshalaliswa kwamandla kwe-Spectral ne-CRI yeLumadoodle

      Kungaba yinselele ukubona ngeso lengqondo umehluko phakathi kokunikezwa kwamandla okubuka kwemithombo emibili elula, ngakho-ke sizogqobhoza amagrafu. Ukusatshalaliswa kwamandla okubukwa kweLumadoodle kuphakanyiswe phambi kweMediaLight Mk2. ILumadoodle ibonakala imhlophe eguquguqukayo nomngcele omnyama kuthi iMediaLight Mk2 ibonakale ngombala. 

      Siyabona ukuthi iLumadoodle idala okumhlophe ngokuhlanganisa ama-phosphors aphuzi (ama-phosphors anebanga eliphakeme le-580 nm) ne-emitter eluhlaza okwesibhakabhaka. Akukho ukuphakama okubomvu noma okuluhlaza kusampula yeLumadoodle (ungenza ukukhanya okumhlophe kwe-CRI ngokuhlanganisa imibala emibili yokukhanya - ophuzi noluhlaza okwesibhakabhaka).  

      Ungabona iziqongo ezihlukile eziluhlaza nokubomvu zeMediaLight Mk2 futhi imibala ebukeka inesibindi kugrafu imelela imibala engekho ku-Lumadoodle spectrum. "Intaba" emhlophe imele izinga lamandla aphezulu we-phosphors ephuzi eLumadoodle.  

      IMediaLight ayiqukethe isiqongo esiphuzi njengoba inhlanganisela yama-phosphors abanzi futhi abanzi-band abomvu naluhlaza ahlanganiswe ne-emitter eluhlaza okwesibhakabhaka ukunikeza iMediaLight Mk2 SPD umumo osondele kakhulu ku-D65, noma "owenziwe nge-D65."

        iziphetho

        Ngenkathi lokhu kuqhathanisa kuvela kumbangi wabo, ngokungafani neminye imikhiqizo emakethe, iLumadoodle ayisho ukuthi yenzelwe ukunemba, futhi intengo iphansi kunentengo yeMediaLight, yize ingekho ngaphansi kwezingcezu ezifanayo ze-LED yempahla. Qhathanisa lokhu nezinkampani ezithembisa okuningi kunalokho ezikulethile. Bathembisa i-CRI yama-76 futhi yilokho okutholayo.

        Izindleko ngokuqinisekile ziyisici futhi ngisho nezibani ezinhle kakhulu zokukhetha ngeke zilondoloze i-TV embi ngezilungiselelo ezingalungile.

        Sincamela ukungathengisi abantu abangadingi noma abafuna ukunemba. Baningi abantu abasebenzisa ama-TV ngqo ngaphandle kwebhokisi kunabantu abalinganisa okuboniswayo kwabo. 

        Siyethemba, nokho, ukuthi sikhombisile ukuthi kungani imikhiqizo yethu ibiza kakhulu ukukhiqiza ukuze ukwazi ukunquma ukuthi yimuphi umkhiqizo olungele wena.

        Naba abasunguli beLumadoodle bekhuluma ngemikhiqizo yabo yokukhanyisa okhetha ukukhetha nokuthi bagxile kanjani okwehlukile. Lokhu akuyona into engavamile. Ama-LED amaningi athengiswa njengezibani zokuchema ayimichilo ye-LED yempahla eyenzelwe izinhloso eziningi, njengezibani zetende.

        Izibani zethu zingenza izibani zamatende ezesabekayo, kepha ziyizibani ezehlukile zokuchema. Kodwa-ke, kunezimo lapho ukunemba kungakhathalekile kangako, futhi ukukhokhela ukunemba akufanelekile izindleko ezengeziwe. Akufanele uthenge okuthile okubiza ngaphezu kokufuna ukukukhokhela izici ongazidingi. 

        Uma ulinganisa i-TV yakho, amalambu anganembile awalinganisa ngokweqile ngombono wombukeli. Umehluko wokuqonda phakathi kokunikezwa kwe-chromaticity nombala we-MediaLight ne-Lumadoodle, ezimweni eziningi, weqise kakhulu kunama-tweaks ozowenza ekubonisweni kwakho, futhi njengoba amalambu enikeza isethenjwa sephuzu elimhlophe elibonakalayo, amashifu abonakalayo ekushiseni kombala futhi i-tint izohambisana nalowo mehluko. 

        Uma isibani esizungezile endaweni yokubuka sifudumele kakhulu futhi sine-thatuv ephakeme kakhulu, sizobukeka siluhlaza futhi sifudumele kunokukhanya kwe-D65 okwenziwe. Njengomphumela, i-TV izobukeka i-magenta futhi ipholile kakhulu kune-D65, noma ngabe isilinganisiwe. 

        Futhi ngaphandle komehluko wokunemba, kukhona ezinye izinto ongathanda ukuzengeza ku-Lumadoodle ukuyenza i-apula-to-apula ukuqhathanisa ngokususelwa kunani, Lezi zinto zifaka irimothi, i-dimmer (amalambu okuchema kufanele setha ku-10% wokukhanya okuphezulu kwesibonakaliso, ngakho-ke udinga i-dimmer) i-adaptha ye-AC, intambo yokwelulwa, ukuminyana kwe-LED ephakeme kanye nesikhathi sewaranti ende kakhulu. Ukungeza izesekeli kuvala igebe lentengo kakhulu. 

        Ukuhweba okuyisihluthulelo kungenye yezindleko uma kuqhathaniswa nokunemba. Uma ungakutholi ukunemba okudingayo, mhlawumbe ukhokha kakhulu, ngaphandle kwentengo ephansi. Futhi, uma ungadingi ukunemba, ungahle ube ngcono ngomkhiqizo oshibhile, kunokuba omunye wemikhiqizo ubuyekezwe kuleli khasi.

        Lokho bekungukuqhathanisa okuthakazelisayo. Yiziphi izibani ongathanda ukuzibona zilinganiswa ngokulandelayo?
