I-Epson PowerLite 1975W iyingxenye yochungechunge lweprojekthi ye-1900 yenkampani. Lo mkhakha uhloselwe amabhizinisi amancane nabasebenzisi emfundweni. Lokhu kungenye yezinhlobonhlobo eziphezulu kunazo zonke ezisemgqeni, ukupakisha eziningi zokusakaza okungenantambo nokubukeka kobuchwepheshe. Kuyinto, ngokwemvelo, futhi phakathi kwendlela ephezulu kakhulu emgqeni.
Ubukhulu
I-Epson PowerLite 1975W iphrojekthi ye-3LCD. Isilinganiso esingu-14,8 amasentimitha ububanzi ngo-11.4 amasentimitha ububanzi ngamasentimitha angu-4,3 phezulu lapho izinyawo zingacatshangwa, okwenza kube mkhulu kunamamodeli afakwe ngezansi kulo mkhakha.
Ilinganisa ngamapounds angu-10.2, okwenza kube nzima kunabo abanye abaprojekthi.
Bonisa ama-Specs
Ukulinganisa kwesibalo sakwa-1975W kubhalwe ngo-16:10, okusho ukuthi kulungile ukubukwa kwesikrini. Isixazululo somdabu ngu-1280 x 800 (i-WXGA), futhi lokhu kungashintsha kabusha ku-640 x 480, 800 x 600, 1280 x 1024, no-1400 x 1050.
Isilinganiso sokuphambene salesi simodeli ngu-10,000: 1.
Ububanzi bokulinganisa ububanzi bubalwa njengo-1.38 (ukusondeza: ububanzi) - 2.28 (ukusondeza: ucingo). I-1975W ingakwazi ukuhlola kusuka kude wamasentimitha angu-30 kuya kwamasentimitha angu-300, okufana ne-Power Lite 1955 .
Ukukhishwa okukhanyayo kubhalwe ku-5000 lumens for color and 5,000 for light white, okufana nokuphakeme kakhulu kulo mzila futhi cishe kufumaneka ngo- 1960 . 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.
Lesi sithombe sisebenzisa isibani esingu-280 W UHE, esinamandla kunamanye izibani emgqeni. Le nkampani ithi lesi sibani siphelela emahoreni angu-4 000 ku-ECO Mode futhi 3.000 ku-Mode Normal (ekugcineni kwayo ephakeme kunezo ezinye izinhlobonhlobo).
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- $ 140 ngenye.
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
I-PowerLite 1975W iphakamisa amandla okulalelwayo ngokufaka isikhulumi esisodwa se-16-watt. (Amamodeli we-step-down emgqeni abe nesipikha se-10-watt.) Lokhu kumele kusetshenziswe ngokuphelele ekamelweni elikhulu.
Umsindo womculo u-31 dB ku-ECO Mode kanye no-39 dB ku-Mode Normal, ngokusho kwe-Epson. Lokhu kungaphakathi kwebanga elijwayelekile lamamodeli we-PowerLite yenkampani.
Amandla angenantambo
Njenge-1945W, i-PowerLite 1975W ihlanganisa amandla we-Wi-Fi akhiwe ngaphakathi, okuvumela ukuthi 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 1975W ingasetshenziswa futhi ngamathuluzi okulawula nokulawula okude okulandelayo: I-EasyMP Monitor neCrestron RoomView.
I-PowerLite 1975W inika amandla nokusebenzisa i-wireless technology usebenzisa iMetcast technology (ukuze ukwazi ukuklama kusuka kuma-smartphone noma amaphilisi). Iphinde isebenzise ubuchwepheshe be-WiDi kumadivaysi e-Intel nokusabalalisa kwe-MHL nokubukisa kusuka kwamanye amadivayisi ahambisanayo e-MHL. (Funda kabanzi mayelana ne- MHL lapha.)
Imigomo
Kukhona izimpendulo eziningi: i-USB (Thayipha A), i-USB (Thayipha B), ikhompyutha 1, ikhompyutha 2, i-HDMI 1 / MHL, i-HDMI 2, iVidiyo, i-Audio kwesokudla nokunxele, i-Audio 1, i-Audio 2, i-Audio, i-Power, i-RS -232c, i-Monitor Out ne-LAN.
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 1975W inombhalisi wohlobo lwe-A, ngeke kudingeke ukuthi usebenzise ikhompuyutha ukuze uvezwe. Ungagcina amafayela akho kumemori ye-memory noma i-hard drive, ukuxhuma kumprojekti, futhi uqhubeke.
Amandla
Ukusetshenziswa kwamandla we-1975W kubhalwe ku-435 watts ku-Mode Normal. Lokhu kuphakeme kunanoma yimaphi amamodeli wezinyathelo ezenzelwe emgqeni.
Ukuphepha
Njengabaningi, uma kungenjalo bonke, abaprojekthi be-Epson, leli liza nechweba likaKensington's Security Lock (indawo evame ukutholakala ekusetshenzisweni nezinhlelo ezithandwayo zokukhiya).
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 nalabanye abakulesi sigaba.
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 ingasetshenziswa futhi ibanga elingamamitha angaba ngu-26.2, eliphindwe kabili ibanga lamanye ama-remotes emgqeni. Indawo ekude ihlanganisa imisebenzi elandelayo: Ukukhanya, ukuphambene, ukukhomba, ukugcwalisa, ubukhali, isignali yokufaka, ukuvumelanisa, ukulandelela, isikhundla, ukushisa kombala kanye nevolumu.
I-PowerLite 1975W 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 1975W inokulungiswa okuqondile okuyi-keystone, kanye ne-"Quick Corner" ubuchwepheshe obukuvumela ukuba ulungise noma yikuphi ikona lesithombe 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 1975W ine-$ 1,999 ye-MSRP.
