Njengombuso we-PowerLite 1930, i- PowerLite 1940W ne- PowerLite 1945W, i -1955 yenzelwe labo abadinga iphrojekthi yebhizinisi, izilungiselelo zemfundo noma indlu yokukhulekela. Cishe ifana ne-1945W, ngaphandle kwezici ezimbalwa.
Ubukhulu
I-Epson PowerLite 1955 iphrojekthi ye-3LCD. Isilinganiso esingu-14,8 amasentimitha ububanzi ngo-10.7 amasentimitha ububanzi ngamamitha angu-3.6 phezulu lapho izinyawo zingacatshangwa.
Le modeli inesisindo esingamakhilogremu angu-8.5. Iba nobukhulu obufanayo nobukhulu bobabili njenge-PowerLite 1930 no-1940W.
Bonisa ama-Specs
Ukulinganisa kwesibalo sakwa-1955 kubhalwe ku-4: 3, okusho ukuthi akuyona into ebonakalayo yokubukwa kwesikrini. Lokhu kungenye yezinto ezahluke kakhulu phakathi kwalesi model kanye no-1945W. Isixazululo somdabu ngu-XGA (1024 x 768).
Isilinganiso sokuphambene salesi simodeli singama-3,000: 1, okuphindaphindiwe, afana nalawa amanye amamodeli amabili emgqeni.
Ububanzi bokulinganisa ububanzi bubalwa njengo-1.38 (ukusondeza: ububanzi) - 2.24 (ukusondeza: ucingo). I-1955 ingayenza ibanga eliqhele ngamasentimitha angu-30 kuya kwamasentimitha angu-300, elingaphansi kuka-1945W (leso sakhiwo senyukela ku-280 amayintshi).
Ukukhishwa okukhanyayo kubhalwe ku-4 500 lumens for color and 4,500 for light white. Umbala nokukhanya okumhlophe kulinganiswa ngokusebenzisa ama-IDMS 15.4 namazinga we-ISO 21118, ngokulandelana, ngokwe-Epson. Lesi esinye isibonelo esibalulekile sendlela le modeli ehluke ngayo kusukela ngo-1945W.
Iprojekti isebenzisa isibani esingu-245-Watt UHE E-TORL (ubuchwepheshe bebani lobu-Epson). Le nkampani ithi lesi sibani sihlala emahoreni angu-4 000 ku-ECO Mode futhi ku-2 500 ku-Mode Normal. Ukukhanya kwesibani kuncane kunamanye amamodeli amasha we-PowerLite, ikakhulukazi lawo anenani eliphansi le-lumen. Lokhu akumangalisi - ukukhishwa okuphezulu kwe-lumen kudinga amandla amaningi esibani - kodwa kusengumsebenzi obalulekile. Uma uthenga iprojekti, isikhathi sokuphila kwesibani siyinto ephawulekayo ngoba ukufaka isibani kungaba yindleko (lokhu akuyona isibani esivamile). Izibani zokushintsha zingasebenzisa i-gamut kuye ngokuthi uhlobo oludingayo, kodwa lindela ukuchitha cishe u-$ 100 ngomunye.
Ukuphila kwamangqamuzana nakho kungashintsha ngokususelwa kuhlobo lokubuka izindlela ezisetshenzisiwe nokuthi yiluphi uhlobo lokusetha olusetshenzisiwe. Njengoba inkampani ibhekisela ezincwadini zayo zomkhiqizo, ukukhanya kwebani kuzokwehla ngokuhamba kwesikhathi.
Izinkomba zomsindo
Njengamanye amamodeli amabili, i-PowerLite 1955 ifika nesishulumi esisodwa se-10-watt. Lokhu ngokuqinisekile kunamandla kunamanye amamodeli amaningi e-Epson ahlose amabhizinisi amancane, futhi aklanyelwe ukuba afanele ukusetshenziswa ekamelweni elikhulu.
Umsindo womculo ngu-29 dB ku-ECO Mode kanye no-37 dB ku-Mode Normal, ngokusho kwe-Epson. Lokhu kumayelana nemigomo yamamodeli we-PowerLite yenkampani.
Amandla angenantambo
Njengomnyaka we-1945W, i-PowerLite 1955 ihlanganisa ukwakheka kwe-Wi-Fi, okukuvumela ukuba usebenzise ngokugcwele uhlelo lokusebenza lwe-Epson's iProjection. Lolu hlelo lokusebenza likuvumela ukuba ubonise futhi ulawule okuqukethwe kusuka kwiprojekitha yakho usebenzisa i-iPhone, iPad noma i-iPod Touch. Isibonelo, uma ufuna ukukhombisa isithombe noma iwebhusayithi ku-iPhone yakho kwisikrini sokubukwa, udinga ukumbhangqa iphrojekitha ngohlelo lokusebenza - ungalokothi ucabangele izintambo ze-USB noma izinti ze-USB.
Uma ungenayo yalezi zidivayisi ze-Apple, ungaphinde ulawule iphrojekitha usebenzisa isiphequluli sekhompyutheni uma iphrojista ixhunywe kunethiwekhi. I-Epson ithi akudingeki ukulanda noma iyiphi isofthiwe futhi isebenza nama-PC nama-Mac.
I-PowerLite 1955 ingasetshenziswa futhi ngamathuluzi okulawula okude nokulawula: i-EasyMP Monitor, i-AMX Duet nokutholakala kwedivayisi, i-Crestron Integrated Partner ne-RoomView, ne-PJLink.
Imigomo
Kunezimpendulo eziningana: i-HDMI eyodwa, i-DisplayPort eyodwa, ividiyo eyodwa ye-RCA, i-VGA D-sub-15-pin (input computer) eyodwa, i-port eyodwa ye-RJ-45, i-port eyodwa ye-RS-232C, i-D-sub eyodwa engu-15 -pini, eyodwa ye-USB Uhlobo A, nohlobo olulodwa lwe-USB B.
Uma ungaqiniseki umehluko phakathi kohlobo lwe-Type A nohlobo lwe-USB B, nasi isifundo esisheshayo nesingcolile umahluko phakathi kwezimpendulo ezimbili: Uhlobo A lubukeka njengetrange futhi luhlobo oluzosebenzisa inkumbulo yememori (ebizwa nangokuthi i-portable flash drive). Ukuma kohlobo B kungashintsha, kodwa ngokuvamile kubonakala njengesikwele futhi kusetshenziselwa ukuxhuma ezinye izithako zekhompyutha.
Ngenxa yokuthi i-PowerLite 1955 ine-Connector ye-Type A, ngeke kudingeke ukuthi usebenzise ikhompuyutha ukuze uthole izinkulumo. Ungagcina amafayela akho kumemori ye-memory noma i-hard drive, ukuxhuma kumprojekti, futhi uqhubeke.
Amandla
Ukusetshenziswa kwamandla ka-1955 kubhalwe ku-353 watts ku-Mode Normal. Lokhu kuphakeme kunama-1945W, okumele kulindeleke ngenxa yezimpawu ezingaphezulu lapho zingase zifeze khona.
Ukuphepha
Njengabaningi, uma kungenjalo bonke, abaprojekthi be-Epson, lokhu kuza nokuhlinzekwa kokukhiya kukaKensington (ibhokisi elivame ukusetshenziselwa ukusetshenziswa nezinhlelo ezithandwayo zokukhiya). Iza futhi nesitika se-password yokwamukela.
I-lens
I-lens ine-zoom yokukhanya. Lesi sihloko esivela ku-website ye-About.com sika-Camcorder ichaza umehluko phakathi kwama-optical optical ne-digital.
Isilinganiso sokusondeza sibhalwe ku-1.0 - 1.6. Lokhu kufana nezinye.
Iwaranti
Iwaranti enomkhawulo weminyaka emibili ifakiwe kumprojekti. Isibani singaphansi kwewaranti yosuku lwezinsuku ezingu-90, okuyinto ejwayelekile Iprojekti iphinde ihlanganiswe ngaphansi kohlelo lwe-Epson's Road Service, oluthembisa ukuthumela ubusuku obunamaprojekti esikhundleni sendawo - mahhala - uma kukhona okungalungile ngeyakho. Ukuphrinta okuhle eceleni, lokhu kuzwakalisa isithembiso esihle sabasemgwaqweni. Kukhona ukhetho lokuthenga izinhlelo ezengeziwe zesevisi enwetshiwe.
Okutholako
Kufakwe ebhokisini: iprojekti, ikhebula lamandla, ikhebula le-VGA, i-remote control kanye namabhethri, ama-software kanye nama-CD omsebenzisi omsebenzisi.
Indawo eyikude ingahle isetshenziswe kude kufike ku-11.5, okuyizinyawo ezimbalwa kunamaphesenti amaningi kunamaprosesa amaningi e-Epson. Indawo ekude ihlanganisa imisebenzi elandelayo: Imodi yombala, ukukhanya, ukuphambene, i-tint, umbala we-saturation, ubukhali, isignali yokufaka, ukuvumelanisa, ukusesha imithombo, ne-Split Screen. Lesi sici sokugcina senza abasebenzisi babonise okuqukethwe kusuka emithonjeni emibili ngesikhathi esisodwa.
Ngaphandle kweSplit Screen nje kuphela, i-PowerLite 1955 ibuye isebenzise ithuluzi le-Epson's Multi-PC Ukusebenzisana, ukuze ukwazi ukubonisa izikrini ezine zekhompyutha ngesikhathi esisodwa. Izikrini eziningi zingabuye zengezwe bese zifakwa esimweni sokulinda.
Le PowerLite 1955 inokulungiswa okuzenzakalelayo okuyi-keystone, kanye nobuchwepheshe bokuthi "Quick Corner" okuvumela ukuthi ulungise noma yikuphi ikona yesithombe ngokuzimela.
Ibuye ine-Captioning Evalelwe ngaphakathi, futhi i-Epson ifake ubuchwepheshe obuningi bokuthuthukiswa kwevidiyo okuhloswe ukuthuthukisa ukusebenza kwevidiyo, njenge-Faroudja DCDi Cinema.
Intengo
I-PowerLite 1955 ine-$ 1,699 i-MSRP, efana ne-1945W. Nakuba kunenani eliphezulu le-lumen, uzobe ufuna ukunamathela ku-1945W uma udinga ukuthi amandla okubukwa kwideskithophu.
