Monga PowerLite 1930, PowerLite 1940W ndi 1945W PowerLite, 1955 yapangidwa kwa iwo amene akufuna projector kwa bizinesi, maphunziro kapena nyumba yopembedza. Ziri zofanana ndi 1945W, kupatulapo zinthu zingapo.
Miyeso
Epson PowerLite 1955 ndi 3LCD projector. Maseŵera ake amayenda masentimita 14,8 m'lifupi ndi 10.7 mainchesi madigiri ndi 3.6 mainchesi pamwamba pamene mapazi saganiziridwa.
Chitsanzochi chikulemera makilogalamu 8.5. Lili ndi miyeso yofanana ndi kulemera monga zonse za PowerLite 1930 ndi 1940W.
Onetsani Mafotokozedwe
Chiwerengero cha chiwerengero cha 1955 chimawerengedwa pa 4: 3, zomwe zikutanthauza kuti sizowoneka bwino kuti aziwoneka bwinobwino. Ichi ndi chimodzi mwa kusiyana kwakukulu pakati pa chitsanzo ndi 1945W. Chikhalidwe cha chikhalidwe ndi XGA (1024 x 768).
Chiŵerengero chosiyana cha mtundu uwu ndi 3,000: 1, chimene, kachiwiri, n'chofanana ndi zitsanzo zina ziwiri mzerewu.
Zowonjezera chiwerengerochi ndi 1.38 (zojambula: lonse) - 2.24 (zojambula: tele). 1955 ikhoza kuyendetsa kuchokera pamtunda wa masentimita 30 kufika mainchesi 300, yomwe ndi yochepa kwambiri kuposa 1945W (njirayi imapita mpaka masentimita 280).
Kuunika kwa kuwala kumatulutsidwa ndi kuwala kwa 4,500 kwa mtundu ndi 4,500 za kuwala koyera. Kuwala ndi kuwala kumayesedwa pogwiritsira ntchito IDMS 15.4 ndi miyezo ya ISO 21118, motsatira, malinga ndi Epson. Ichi ndi chitsanzo china chofunika kwambiri cha momwe chitsanzochi chikusiyana ndi 1945W.
Pulojekitiyi imagwiritsa ntchito nyali ya UHE E-TORL 245-Watt (teknoloji ya nyali ya Epson). Kampaniyo imati nyali iyi imatha maola 4,000 mu ECO Mode ndi 2,500 mu Machitidwe Ochizolowezi. Moyo wa nyali ndi wochepa kwambiri kuposa mafano ambiri atsopano a PowerLite, makamaka omwe ali ndi chiwerengero chochepa cha lumen. Izi sizodabwitsa - kupambana kwa lumen kumafuna mphamvu yambiri ya nyali - koma izi ndizofunika kwambiri. Pogula projector, nthawi ya moyo wa nyali ndi yofunika kwambiri chifukwa kukhala m'malo mwa nyali kungakhale kovuta (iyi si babu wamba). Mafuta osinthika akhoza kuyendetsa masewera malinga ndi mtundu womwe mukufunikira, koma kuyembekezerani kuti muwononge ndalama zokwana madola 100 pa imodzi.
Moyo wa nyali ungasinthenso mosiyana ndi mtundu wa njira zowonera zomwe zikugwiritsidwa ntchito ndi mtundu wanji wazogwiritsiridwa ntchito. Monga momwe kampani ikusonyezera mu zolemba zake zopangidwa, kuwala kwa nyali kudzachepa pakapita nthawi.
Nkhani Zomveka
Mofanana ndi mafano ena awiri, PowerLite 1955 amabwera ndi wolankhula 10-watt. Izi ndi zowonjezereka kwambiri kuposa zitsanzo zambiri za Epson projector zogwirira ntchito zamalonda ang'onoang'ono, ndipo zalinganizidwa kukhala zoyenera kugwiritsa ntchito m'chipinda chachikulu.
Phokoso la fan ndi 29 dB mu ECO Mode ndi 37 dB mu Machitidwe Ochizolowezi, malinga ndi Epson. Izi ndi zowonjezera zitsanzo za PowerLite za kampani.
Zosayenerera opanda waya
Monga 1945W, PowerLite 1955 ikuphatikizapo Wi-Fi yokhazikika, yomwe ikukuthandizani kuti mugwiritse ntchito pulogalamu ya Epson ya iProjection. Mapulogalamuwa amakulolani kusonyeza ndi kuyendetsa zinthu kuchokera pulojekiti yanu pogwiritsa ntchito iPhone, iPad kapena iPod Touch. Mwachitsanzo, ngati mukufuna kusonyeza chithunzi kapena webusaiti pa iPhone yanu mpaka pulojekiti yowonekera, muyenera kungoyang'ana pulojekiti ndi pulogalamuyi - musamaganizire zingwe za USB kapena ndodo za USB.
Ngati mulibe zipangizo zamapulogalamu awa, mukhoza kuyang'anira pulojekitiyo pogwiritsa ntchito osuta makompyuta ngati pulojekiti ikugwirizanitsidwa ndi intaneti. Epson akuti simukufunikira kukopera pulogalamu iliyonse ndipo imagwira ntchito ndi ma PC ndi Mac.
PowerLite 1955 ikhozanso kugwiritsidwa ntchito ndi zipangizo zotsatirazi: • EasyMP Monitor, AMX Duet ndi Discovery, Crestron Integrated Partner ndi RoomView, ndi PJLink.
Zotsatira
Pali zifukwa zingapo: HDMI imodzi, One DisplayPort, RCA imodzi yamavidiyo, awiri VGA D-sub-pin-15 (pulogalamu yamakina), sewero limodzi la RJ-45, sewero la RS-232C limodzi, D Pangani, mtundu umodzi wa USB A, ndi mtundu umodzi wa USB B.
Ngati simukudziwa bwino kusiyana kwa mtundu wa mtundu A ndi mtundu wa B B, apa pali phunziro lachidule komanso loipa pa kusiyana pakati pa zigawo ziwiri: Mtundu wa A umawoneka ngati rectangle ndipo ndiwo mtundu umene muti mugwiritse ntchito ndi chikumbutso cha kukumbukira (chomwechonso chimatchedwa flash portable drive). Mapangidwe a mtundu B akhoza kusiyana, koma nthawi zambiri amawoneka ngati malo amodzi ndipo amagwiritsidwa ntchito polumikiza zipangizo zina zamakompyuta.
Chifukwa chakuti PowerLite 1955 ili ndi mtundu wa A A chojambulira, simudzasowa kugwiritsa ntchito makompyuta pamakambidwe. Mukhoza kusunga mafayilo anu pamtundu wa memory kapena hard drive, kulumikiza ku projector, ndi kupitiriza.
Mphamvu
Kugwiritsiridwa ntchito kwa mphamvu kwa 1955 kunalembedwa pa 353 Watts mu Njira Yoyenera. Izi ndi zapamwamba kuposa 1945W, zomwe ziyenera kuyembekezera chifukwa cha lumens kwambiri zomwe zingagwire ntchito.
Chitetezo
Monga ambiri, ngati si onse, ojambula a Epson, awa amabwera ndi kensington's lock lock (malo omwe amapezeka kuti agwiritsidwe ntchito ndi machitidwe otchuka otsekemera a Kensington). Ikubweranso ndi choyimira chinsinsi.
Lens
Lensulo ili ndi zojambula. Nkhaniyi kuchokera pa tsamba la About.com ya Camcorder ikufotokoza kusiyana pakati pa zoom optical ndi digito.
Zowonetsera zowerengera zalembedwa pa 1.0 - 1.6. Izi ndi zofanana ndi zina.
Chivomerezo
Chigamulo chokhazikika cha zaka ziwiri chikuphatikiziridwa kwa projector. Nyali ili pansi pa masiku 90, chomwe chimagwiritsidwa ntchito pulojekitiyi imayang'aniranso ndi Epson's Road Service Program, yomwe imalonjeza kuti kamodzi kanyamulo kameneko kamangotengedwa - kwaulere - ngati chinachake chiri cholakwika ndi chanu. Kusindikizira pambali, izi zikuwoneka ngati lonjezo labwino kwa ankhondo apamsewu. Pali mwayi wogula zina zowonjezera mapulani.
Zimene Mumapeza
Zomwe zili m'bokosi: Projector, cable power, vGA-VGA cable, remote control ndi mabatire, mapulogalamu ndi ma CD CD.
Kutalikiranso kungagwiritsidwe ntchito patalika kufika pa 11.5, omwe ali ochepa kwambiri kuposa owonetsa Epson ambiri. Kutalika kumaphatikizapo ntchito zotsatirazi: Zojambulajambula, kuwala, zosiyana, zojambulajambula, zowonjezera mtundu, kuwunika, chizindikiro chowunikira, kusinthasintha, kufufuza kwa magetsi, ndi Split Screen. Chigawo chotsirizachi chimapangitsa ogwiritsa ntchito kusonyeza zinthu zochokera kuzinthu ziwiri zosiyana pa nthawi yomweyo.
Pambuyo pa Split Screen basi, PowerLite 1955 imaphatikizapo chida cha Epson Multi-PC Chigwirizano, kotero mukhoza kusonyeza makanema anayi a makompyuta pa nthawi yomweyo. Zowonjezera zambiri zingathe kuwonjezeredwa ndi kuyika pazithunzi zoyimirira.
Mphamvu iyi ya 1955 ili ndi kukonzanso mwala wowongoka, komanso "Technology Quicker" yomwe imakupangitsani kuti musinthe mtundu uliwonse wa fano.
Iwenso ili ndi malemba otsekedwa, ndipo Epson yaphatikizapo matepi angapo opanga mafilimu opanga mafilimu omwe amatanthawuza kukonza mavidiyo, monga Faroudja DCDi Cinema.
Mtengo
PowerLite 1955 ili ndi $ 1,699 MSRP, yomwe ndi yofanana ndi 1945W. Ngakhale kuti ili ndi chiwerengero cha lumen chokwanira, mufunabe kumamatira ndi 1945W ngati mukufuna kuti mawonekedwe awonekera.
