The Lumens Game
Paunofunga nezvekutenga vhidhiyo projector, zvichida kunyanya kujekesa kwaunoziva ndeye nhamba yechiedza. Lumens inguva yehuwandu hwechiedza chevhidhiyo projector inogona kubudiswa. Zvechokwadi, sezvakangoita nezvimwe zvinyorwa, apo mugadziri anopa chirevo chekucherechedza nhamba, iwe unofanira kungwarira sezvo pasina mhizha inonyanya kudiwa kuti ishandiswe-saka zvakataurwa kuti Lumens yero inoshandiswa neimwe chigadzirwa chezvirara zvingasava zvakafanana seimwe chiratidzo. Zvisinei, kana kuyerwa kwechiedza kunotaurwa maererano neAnsi lumens, iyo ndiyo inoshandiswa mumabhizimisi isingagumi kana ichifananidza mabhii maviri uye vose vari kushandisa ANSI sevanotaura.
White Light Output vs Mucherechedzo
Zvisinei, kune zvakawanda zvokufungisisa mumashoko ekuti chiedza chevhidhiyo projector chinogona kubudiswa sei. Kana imwe tsanangudzo yemwenje inotaurwa, iyo inotsanangurwa ndeyekuti White Light Output (WLO) kana White Brightness, iyo projekiti inokwanisa kubudisa, kwete iyo chiedza chekubuda kana ruvara rwunotorwa mukufungisisa. Semuenzaniso, mapurojekiti maviri anogona kunge akafanana neWLO, asi ruvara rwekuyera (CLO), kana kuti Color Brightness, runogona kunge rwakasiyana.
Kurutivi-nerutivi Kuenzanisa
Kuti uenzanise musiyano uri pakati peChitsvuku neKuchenesa Kwemoto, chinyorwa chiri pamusoro apa chinoratidza kurati-ne-ruvara kuratidzwa kwechigadzirwa chemuvara pane video projoror lights, kana chiedza, zvakabuda. Zvose zviri kujekesa mumifananidzo zvine White Brightness zvakaenzana asi zvakasiyana nehuwandu hweBlue Bright ivo vanogona kuronga.
Chikonzero chokuti pane musiyano muChiratidzo Bhuni chemapurojekiti maviri ndechokuti purojekiti kurutivi rworuboshwe anoshandisa 1-chip DLP design (Optoma GT750E), nepo purojekiti iri kurudyi yakashandiswa 3LCD design (Epson PowerLight Home Cinema 750HD). Zvose zviri kujekesa zvine chimiro chakafanana chekuratidza kuratidzwa kwechizvarwa ( 720p ) uye ANSI imwechete lumens WLO tsanangudzo: 3,000. Chiyero chakasiyana chakasiyana cheOptoma chinokwana 3,000: 1 uye yeEpson inonzi "kusvika ku" 5,000: 1.
Zvisinei, sezvaunogona kuona, purojekiti iri kurudyi inoratidzika kuva yakanyatsojeka, mavara mazhinji ane simba, pamwe nekupenya kwakakwana, kupfuura purojekiti kuruboshwe.
Nzira yei Projector Technology Design Inobata Mavara Akanaka
Chikonzero chekusiyana mumifananidzo chaiyo yakaratidzwa, iyo yaunoona mumufananidzo, inonyatsopindirana nekugadzirwa kwemapurojekiti maviri. The 3LCD design inobvumira zvose zvitsvuku uye ruvara ruvara kuti zvipfuure kuburikidza ne-lens nguva dzose, kujekesa uye kuenzana kweWhite uye Color Brightness. Zvisinei, mune 1-Chip DLP yekugadzira , chiedza chinofanira kufamba nechitsipa chemavara chinoparadzaniswa chakaparadzaniswa sezvikamu zvitsvuku, zvitsvuku, uye zvebhuruu.
Mu 1-chip DLP system, mavara anofungidzirwa sequentially (mune mamwe mazwi, ziso rako harisi kugamuchira ruzivo rwemuvara nguva dzose), izvo zvinogona kukonzera kuwandisa kwemavara ekubuda kwechiedza, maererano nechechi chiedza chinobuda. Kuti uwane chikwereti ichi, 1-chip DLP projekisi kakawanda kuwedzera chikamu chechichena kune girazi kuti riwedzere Icho Chiedza, asi chokwadi chinoramba chiripo kuti dhigirii yeBlue Brightness iri pasi peBlack Brightness.
Ichi chiyamuro kazhinji hachireviki nemuumbi wezvinangwa zvepurojekiti. Izvo zvaunoona kakawanda ndeye Lumens imwechete yezvinyorwa, pane imwe inogona kunyora mbiri lumens tsanangudzo, imwe yeWLO (White Light Output) uye imwe yeCLO (Color Light Output), inopa huwandu hwakajeka hwehuwandu hweBlack Brightness iyo projector inogona kubudisa.
Kune rumwe rutivi, 3LCD Projectors vanoshandisa girazi regirazi / prism (pasina kufamba kwemavhiri gorosi) pamwe chete nechipfeko chakasiyana chemuvara wega wega wekutanga (nyekundu, makaro, bhuruu), saka zvose zviviri zvichena uye maruva zvinoramba zvichisvika paziso rako. Izvi zvinoguma neChite White uye Bright Brightness.
Semugumisiro wakananga wekombiyuta inoshandiswa kujekesa mifananidzo kubva pane imwe shanduro inoshandiswa mumufananidzo uri pamusoro, kuti 1-chip DLP projector kuruboshwe kuti ibudise zvakajeka Mucherechedzo Wemavara se 3LCD projectorori kurudyi, inoda kuva nezvakawanda Kukwidziridzwa kweGreen White Kubudirira kunopfuura purojekiti iri kurudyi - izvi zvinoreva kuti 1-chip DLP projector inofanira kushandisa mwenje wepamusoro-mvura, uye kuwedzera kwekushandisa kwesimba.
Kutora Kwokupedzisira - Sei Kuratidza Kujeka Kwakakosha?
Sezvaunogona kuona nemufananidzo wekumufananidzo uri pamusoro peji, Bhari Bright inogadzirisa pane zvaunoona pahwindo. Izvi zvingave zvakakosha zvakanyanya kwete kungofanirwa kutarisa imba yemitambo yekuona, asi pakuona mumakamuri umo kuvepo kwechiedza chakanaka kuchigona kukwanisa kutaridzika nyore, 3D kuona, apo kurasikirwa kwemazuva kana kutarisa kuburikidza nemagirazi e 3D chinhu, uye kune avo iyo inoshandisa vhidhiyo mapurogiramu muzvidzidzo, bhizinesi, kusanganisira kufamba, apo purojekiti inogona kushandiswa mumakamuri akasiyana-siyana uko kurairika kwekudzivirira kusingazivikanwe pamberi pezvokudya.
Uyewo, kuwedzera ruvara rucheno kunowedzerawo maonero ezvinyorwa mukati memufananidzo, pasinei nekugadzirisa kuratidzwa. Chinhu chimwe chete chinogona kutambura apo ruvara ruchenekera rwakawedzerwa huwandu hwehutano hwakasiyana. Zvisinei, pane mamwe mavhidhiyo ekugadzirisa zvinhu anogona kuchinja izvi.
Kuti uwane mamwe mashoko pamusoro peChiratidzo Brightness Standard, tarisa kune Chiziviso Chakatemwa uye Color Brightness Standard White Paper.
Uyewo, kuti uenzanise Bhuku Rokutaura tsanangudzo yekusarudza vhidhiyo vhidhiyo, chengetedza Muvaravara Wechivara Pakubuda Purogiramu Peji.
Kuti uwane zvakawanda pamusoro peLumens uye Brightness, uyewo kuti video projector light output inorevei neTV chiedza chekubuda , titaurire shamwari yedu nyaya: Nits, Lumens, uye Bright - TVs vs Video Projectors .
