Projectors LED: ndemanga za opanga ndi kubwerezanso zitsanzo zabwino

Popeza zikamera wa msika za magetsi banja projectors zasintha kwambiri. Si anthu zipangizo zodula ndi utumiki mochepa mtengo, ntchito zomwe zinali zotheka mu mdima. Lero, pogwiritsa ntchito limakupatsani kuona zithunzi ndi mavidiyo mosavuta m'malo TV kapena PC chophimba. Ndi mtengo zitsanzo amene amathandiza chigamulocho a Full HD, wofanana ndi mtengo wa mawailesi akanema 40 inchi. Ndi nthawi kuti agwiritse ntchito njira imeneyi ndi kukhala mwini wokondwa wa zisudzo kunyumba ndi chophimba moona chachikulu ndi 300 inchi opendekera, ndiwo za 7,62 m.

chithunzi

The chizindikiro chachikulu cha kusankha ndi khalidwe chifanizo cha purojekitala lapansi. Koma kodi kukhala ngati zochepa zofunika kwambiri ziyenera sakupitanso zitsanzo zodula makina chifukwa cha kusowa zipinda maganizo?

Khalidwe chifanizo cha zolosera angakhale magawo amenewa:

• kulingalira luso;
• kukula ndi Maganizo a masanjidwewo ndi;
• tisiyanitse;
• kuwala;
• ndi Utali.

Choyamba, fano khalidwe zimadalira luso ziyerekezo. Tsopano pali njira zamakono atatu: DLP, LCD ndi LCOS.

DLP

DLP (Engl. Intaneti Kuwala Processing) amagwiritsa bokosi kusintha ndingaliro ngodya ya micromirrors kuti atsogolere kuwala mu mandala moganizira. mtengo ankaudaya kumachitika m'njira zosiyanasiyana. Anthu ena opanga ntchito mofulumira onsewo gudumu galu. Pankhaniyi, diso akuona milozo monochrome chithunzi zimene zingakhudze anthu ena, komanso amalenga utawaleza zotsatira zoletsa kuti kuonera. Ena amagwiritsira atatu micromirror lomenyera aliyense mtundu payokha (3DLP luso). Projectors kuti ntchito 3DLP-luso, ali pakati pa zabwino, koma projectors mtengo kwambiri.

LCD

LCD luso (Engl. Phula Crystal Sonyezani) amagwiritsa atatu LCD masanjidwewo kupanga wofiira, wobiriwira ndi buluu zigawo za kanema chizindikiro. The otaya kuwala zitsulo halide nyale umadutsa ndi prism kapena ndondomeko ya fyuluta dichroic kuti transmits gawo limodzi la sipekitiramu ndi Kuganizira wina ogaŵikana zigawo zitatu. Aliyense anatumiza kudzera mwa LCD-masanjidwewo kuti ndi kusintha kamwazi kuwala kudutsa aliyense mapikiselo amalenga fano monochromatic. Pawiri zigawo zikuluzikulu zitatu umabala Mipikisano mtundu ziyerekezo. Pakati pa zovuta njira imeneyi imatchedwa otsika Mosiyana fano (chifukwa chakuti galasi ndi boma chatsekedwa transmits kuwala, ndipo osapitirira 7% ya masanjidwewo bandiwifi).

LCOS

LCOS (Engl. Phula Crystal pa pakachitsulo) zochokera yapita awiri. Koma kuwala si kudutsa masanjidwewo madzi galasi, ndipo potengera madzi galasi pa pakachitsulo. Izi zimachititsa zithunzi apamwamba popanda zovuta za DLP- ndi LCD-sayansi. Komanso, n'zotheka kuonjezera mapikiselo osalimba ndi kukwaniritsa mkulu chithunzi kusamvana. Koma mtengo-LCOS projectors si mkulu, mpaka okha cinemas awo ntchito ndi zipinda zazikulu ulaliki.

LED

LED luso (Engl. Kuwala emitting Diode, anatsogolera) polenga fano pogwiritsa ntchito njira pamwamba ndi kusiyana kumene gwero kuwala pano ndi bokosi LED. Izi kumatha kufunika nyale m'malo, mowa mphamvu yafupika. Kungakupatseni moyo wa khamu la LED ndi 25 zikwi. Maola. The sangathe ndi yaing'ono kuwala kamwazi osati choposa 2,000 lumens.

Laser purojekitala ali okonzeka ndi gulu la laser diodes mitundu yaikulu. Zotsikirako mtengo ndi hybrid laser LED projectors, imene kukwaniritsa mkulu kuwala diode laser amaphatikizidwa buluu, wobiriwira ndi wofiira fulorosenti mchitidwe LEDs.

choyendetsera

Maonekedwe anatsimikiza ndi nambala ya pixels. Pakuti mkulu khalidwe chithunzi purojekitala ndi magawo awa ayenera kufanana gwero. Mukhoza kusewera kumbuyo mbendera ndi chikalata osiyana, koma fano lidzachokera molakwika ndi ma aligorivimu ndi psinjika.

Popular mwaubwino ndi 1280 x 768 WXGA, 1280 x 720 HD, 1920 x 1080 Full HD, 1920 x 1200 WUXGA.

kuwala

Wowala kamwazi amayezedwa lumens. Projectors ndi chinyezimiro cha 2000-3000 lumens ntchito m'makalasi ndi zipinda msonkhano waung'ono. Wowala kamwazi mu 3000-4500 lumens oyenera zipinda zazikulu msonkhano. Kunyezimira kwa fano mu nkhani iyi ndi chokwanira, kuti mdima chipinda. A wapamwamba-kuwala projectors 4500 lumens ntchito pa zoimbaimba, mu mabala usiku, mipingo ndi zina zotero. D. Cheap ndi laling'ono projectors kunyamula ndi kamwazi wowala wa lumens 2,000 amafuna zochepa okwana kapena tsankho asiyane chipinda.

tisiyanitse

The chiŵerengero cha luminance wapamwamba ndi kunsi kwa nsalu yotchinga imatchedwa kusiyana chiŵerengero cha purojekitala lapansi. Mwachitsanzo, kusiyana 10,000: 1 limasonyeza kuti kuwala woyera kuposa kuwala kwa wakuda nthawi 10 000. Mosiyana nezatemnonnom chipinda angaimbidwenso ndi magwero kunja kuwala ndi mmene otsika wa kamwazi wowala wa purojekitala kufunika.

mandala

Video projectors magalasi akhoza zokuzira ndi kusintha Buku kapena basi ya kutalika focal. M'pofunika kusintha chithunzi popanda kusuntha pogwiritsa ntchito yokha.

Komanso, disolo amakhala ndi chiŵerengero cha mtunda kuchokera chophimba kuti kukula kwake. Projectors ndi kuleza cholinga (2-8: 1) muyezo (1-2) ndi yochepa cholinga (zosakwana 1).

Features LED-projectors

• ntchito m'nyumba amafuna shading kwa sharpness pazipita ndi kuwala kwa fano.
• Zipangizo ndi kamwazi wowala wa lumens 300 mopitirira pa m'lifupi 0.2 mamita nsalu yotchinga, ndipo oposa 500 lumens - 3 m.
• Oyenera kunyumba zisudzo yam'manja. Si m'malo lathunthu projectors ndi nyali zitsulo halide.
• Portability zimatheka ndi kukhalapo kwa yobweretsa kunja mphamvu, imapanga opanda zingwe.
• Chitsanzo ndi mkulu wowala kamwazi wa mkulu mlingo phokoso, kotero oyenera kugwiritsa ntchito m'malo onse.
• Mphamvu mowa ndi kochepa.

Purojekitala anatsogolera: mwachidule za anthu otchuka

Tsiku lililonse pa msika, zitsanzo watsopano projectors, gwero kuwala imene LEDs ntchito. M'munsimu muli yekha LED-projectors, amene ndemanga anali positive. Choncho tiyeni tiyambe.

Mini LED-purojekitala ViewSonic PLED-W800 - Pocket chipangizo anafuna kuti ulaliki malonda, monga iwo amati, "pa ntchentche". Koma, malinga ogula linanena bungwe kuwala zimathandiza kuti ntchito kunyumba.

ViewSonic California kampani okhazikika zipangizo ziyerekezo ku 80s mochedwa. Zaka zingapo zapitazo izo zakhala mpainiya malire atsopano a mini-LED-projectors ndi chitsanzo PLED-W500. zitsanzo tsopano likupezeka W200, W600 ndi W800.

manambala mu dzina chitsanzo limafanana ndi mphamvu ya kamwazi wowala mu lumens. Pa pepala fanizo ndi mphamvu zitsulo nyali halide, amene alumphe 2000 lumen, sayankhula mokomera LED-purojekitala, komabe, monga ndemanga kasitomala, chipangizo kumathandiza yotchinga ndi wowala kuposa kuyembekezera. The chipangizo kunyamula akhoza kuchita ulaliki PowerPoint, kupereka 80 inchi HD chithunzi 1280 × 720 pa mtunda wa 2.5 mamita kwa kuwala popanda asiyane chipinda. Komabe, muyenera kukhala mafilimu adzakhala zadornut makatani ndi kusinthana kwa mode Movie kupereka fano mtundu kwambiri zachilengedwe. The compactness chipangizo chofunika kuti apereke kusintha m'litali focal. Koma pali phiri kwa ogwiritsa pa miyendo itatu ndi. Ngati purojekitala ndi linapendekeka poyerekezera ndi nsalu yotchinga, chifanizo adzakhala basi kusintha.
