NjengoMandla eLite 1930, i- PowerLite 1940W kunye ne- PowerLite 1945W, i-1955 yenzelwe abo bafuna iphrojekithi kwishishini, imfundo okanye indlu yonqulo. Kuphantse kufana ne-1945W, ngaphandle kwezinto ezimbalwa.
Ubukhulu
I-Epson PowerLite 1955 iprojekti ye-3LCD. Ilinganiselwa kuma-14,8 intshi ububanzi nge-10,7 intshi ububanzi ngo-3.6 intshi ephezulu xa iinyawo zingakhange ziqwalaselwe.
Lo mzekelo unesisindo kuma-8.5. Inokulingana kunye nobukhulu obufanayo kunye ne-PowerLite 1930 no-1940W.
Bonisa iinkcukacha
Umlinganiselo wendawo yokuzalwa ka-1955 ubhalwe ku-4: 3, oku kuthetha ukuba akuyona into efanelekileyo yokubukela kwideskrini. Lo ngenye yezinto eziphambili kakhulu phakathi kwalo mzekelo kunye no-1945W. Isisombululo sesidalwa ngu-XGA (1024 x 768).
Umlinganiselo ochaseneyo kule modeli ngu-3,000: 1, ephindaphindiweyo, efana nezinye iimizekelo ezimbini kumgca.
Ukuphonsa umlinganiselo wezinto ezidweliswe njenge-1.38 (ukusondeza: ububanzi) - 2.24 (ukusondeza: ifoni). I-1955 ingenza iprojekti ukusuka kumgama wama-intshi angama-30 ukuya kuma-intshi angama-300, nto leyo ingaphantsi kwe-1945W (loo modeli iya kuma-intshi angama-280).
Ukuveliswa kokukhanya kubhalwe kwiimitha ezi-4 500 zombala kunye no-4 500 ukukhanya okumhlophe. Umbala kunye nokukhanya okumhlophe kulinganiswa kusetyenziswa ii-IDMS 15.4 kunye nemigangatho ye-ISO 21118, ngokulandelanayo, ngokwe-Epson. Lo ngowomnye umzekelo obalaseleyo wendlela lo mzekelo uhluke ngayo ngo-1945W.
Iprojekti isebenzisa isibane esingu-245-Watt UHE E-TORL isibane (ubuchwepheshe beeteknolo ye-Epson). Inkampani ithi lesi sibane sihlala kwiiyure ezingama-4 000 kwi-ECO Mode kunye ne-2,500 kwiNdlela eqhelekileyo. Ubomi besibane buncinci kunezona ezininzi zeModeli ezitsha zamandla, ngokukodwa ezo zibalo ezincinane ze-lumen. Oku akumangalisi-ukuphakama kwe-lumen ephakamileyo kufuna amandla angaphezulu kwesibane-kodwa kuseyona nto ibalulekileyo. Xa kuthengwa iphrojekithi, isibane sokuphila sisibane kubaluleke kakhulu kuba ukutshintshwa kweso sibane kungabaluleka (akusikho i-bulb light light). Izibane zendawo ziyakwazi ukuqhuba i-gamut ngokuxhomekeka kwimihlobo oyifunayo, kodwa ulindele ukuchitha i-$ 100 enye.
Ubomi bomnxeba buyahlukahluka ngohlobo lweendlela zokubukela ezisetyenzisiweyo kwaye luhlobo luni lokusetyenziselwa. Njengoko inkampani ichaza kwincwadi yayo yemveliso, isibane sokukhanya siza kuhla kwexesha.
IiNkcazo zomsindo
Njengaye eminye imodeli, i-PowerLite 1955 iza nesithethi esisodwa se-10-watt. Oku kuninzi kunamandla kunamanye amanqaku eprojekthi e-Epson ajongene namashishini amancinci, kwaye yenzelwe ukuba ilungele ukusetyenziswa kwigumbi elikhulu.
Ingxolo yomsindo ingu-29 dB kwindlela ye-ECO kunye ne-37 dB kwimodi eqhelekileyo, ngokwe-Epson. Oku malunga nomgangatho wemodeli ye-PowerLite yenkampani.
Amandla angenazintambo
Njengo-1945W, i-PowerLite 1955 ibandakanya ukuxhotyiswa kwe-Wi-Fi, kukuvumela ukuba usebenzise ngokupheleleyo i-Epson iProjection. Le ncedisi ikuvumela ukuba ubonise kwaye ulawule okuqukethwe kwiprojekti yakho usebenzisa i-iPhone, iPad okanye iPod Touch. Umzekelo, ukuba ufuna ukubonisa isithunzi okanye iwebhusayithi kwi-iPhone yakho kwisikrini esicacisiweyo, kufuneka udibanise iprojekti kunye ne-app - ungaze ucinge iingcingo ze USB okanye iintonga ze-USB.
Ukuba awunayo enye yalezi zixhobo ze-Apple, unokulawula kwakhona iphrojekti usebenzisa isiphequluli sekhompyutheni ukuba iphrojekithi ixhunyiwe kwinethiwekhi. U-Epson uthi akukho mfuneko yokukhuphela nayiphi na isofthiwe kwaye isebenza kunye nee-PC nee-Mac.
I-PowerLite 1955 ingasetyenziselwa kunye nezixhobo zokulawula ezikude kunye nezixhobo zolawulo: I-EasyMP Monitor, i-AMX Duet kunye nokuFumana iCandelo, i-Crestron Integrated Partner kunye ne-RoomView kunye ne-PJLink.
Iziphumo
Kukho iziphumo ezininzi: enye i-HDMI, enye i-DisplayPort, enye i-video ye-RCA, i-VGA ye-D-sub-15-pin (input computer), enye ye-port ye-RJ-45, enye ye-RS-232C port, enye ye-D-sub-15. -pin, olunye uhlobo lwe-USB, kunye nohlobo olulodwa lwe-USB B.
Ukuba awuqinisekanga ukuba umehluko phakathi kohlobo lwe-A kunye nohlobo lwe-B b USB, nantsi isifundo esheshayo nesingcolileyo kumbambiswano phakathi kweempembelelo ezimbini: Uhlobo lwe-A libukeka njengomxande kwaye luhlobo oluya kulusebenzisa inkumbulo yememori (ebizwa ngokuba yi-flashable flash drive). Ubume bohlobo B luyahlukahluka, kodwa luhlala lubonakala njengekwere kwaye lusetyenziselwa ukudibanisa ezinye iinkalo zekhompyuter.
Ngenxa yokuba iPowerLite 1955 inomnxibelelisi wohlobo lwe-A, awunakufuneka ukuba usebenzise ikhomputha. Ungagcina iifayile zakho kwi-memory stick okanye kwi-hard drive, xhuma kwiprojekti, kwaye uqhubeke.
Amandla
Ukusetyenziswa kwamandla ngo-1955 kubhalwe kwi-353 watts kwiNdlela eqhelekileyo. Oku kuphakamileyo kunama-1945W, okumele kulindeleke ngenxa yeempawu ezingaphezulu apho zingenza iprojekthi.
Khu seleko
Njengowonke, ukuba akunjalo bonke, abaprojekthi be-Epson, eli liza nelungiselelo lokukhiya i-Kensington (indawo efunyenwe ngokuqhelekileyo isetyenziselwa ukusetyenziswa kunye neenkqubo ezikhuselekileyo ze-lock). Iza kunye nesitifiketi sokuxhaswa ngegama.
Lens
I-lens ine-zoom zoom. Eli nqaku elivela kwi-About.com ye-Camcorder site ichaza ukungafani phakathi kwezinto ezibonakalayo kunye ne-digital.
Isilinganiselo sokusondeza sibhalwe kwi-1.0 - 1.6. Oku kuyafana nabanye.
IWaranti
Iwaranti eminyaka emibini engagqithwanga ifakwe kwiprojekti. Isibane singaphantsi kwe-warranty yeentsuku ezingama-90, okuqhelekileyo Iprojekti iphinde ihlanganiswe phantsi kwe-Epson's Road Service Program, ethembisa ukuthumela ubusuku beprojekthi yesikhokelo-ngokukhululekile-ukuba kukho into engalunganga yakho. Ukushicilelwa okulungileyo eceleni, oku kufana nesithembiso esihle kwiimfazwe zendlela. Kukho ukhetho lokuthenga izicwangciso ezongezelelweyo zenkonzo.
Oko Ufumanayo
Kubandakanywe kwibhokisi: iprojekti, i-cable, i-component-to-VGA ikhebula, ukulawula okude kunye neibhetri, isofthiwe kunye ne-CD yomsebenzisi.
Indawo ekude ingasetyenziselwa kude kumgama we-11.5, owona ambalwa amancinci kunamaprojekti amaninzi e-Epson. Iimpawu ezikude ziquka imisebenzi elandelayo: Imodi yembala, ukukhanya, ukungafani, i-tint, umbala we-color, ukukhanya, uphawu lokufakelwa, ukuvumelanisa, ukukhangela umthombo kunye ne-Split Screen. Olu hlobo lokugqibela lunceda abasebenzisi ukuba babonise umxholo ovela kwimithombo emibini eyahlukeneyo ngexesha elifanayo.
Ngaphandle kweSplit Screen nje kuphela, i-PowerLite 1955 inomsebenzi we-Epson's Multi-PC Colaboration tool, ukuze ukwazi ukubonisa izikrini ezine zekhompyutha ngexesha elifanayo. Izikrini ezingaphezulu zingaphinde zongezwe kwaye zifakwe kwimodi yokulinda.
Le PowerLite ngo-1955 ibonisa ukulungiswa kwamatye okuzitshixo ngokuzenzekelayo, kunye ne-"Quick Corner" iteknoloji ekuvumela ukuba ulungelelanise nayiphi na ikona yomfanekiso ngokuzimela.
Kwakhona uye wakha kwi-Captioning Closed, kwaye i-Epson ifake ubugcisa obuninzi bokuphucula iikhompyutha ezibhekiselele ekuphuculeni ukusebenza kwevidiyo, njenge-Faroudja DCDi Cinema.
Ixabiso
I-PowerLite 1955 inemali eyi-1,699 ye-MSRP, efana ne-1945W. Nangona kunomlinganiselo ophezulu we-lumen, uya kuqhubeka unamathela kwi-1945W ukuba ufuna ukuba ukubukela kwideskrini.
