Amaphrojektha okujikijela amafushane: okudingeka ukwazi ngawo, amamodeli angcono kakhulu

Abasebenzisi bethelevishini besimanje bakhetha iprojektha yokuphonsa emfushane esikhundleni se-“box2” evamile. Yiziphi izici zomsebenzi wakhe? Futhi futhi ihluke kanjani ku-projektha evamile? Lokhu nokunye okuningi kuzoxoxwa ngakho kulesi sihloko.

Iyini iprojektha yokuphonsa okufushane futhi isebenza kanjani?

Njengomphumela weqiniso lokuthi iprojektha yokuphonsa isikhashana inamalensi akhethekile nezibuko ezikuvumela ukuthi udale isithombe esikhulu futhi usibonise esikrinini, ekubeni ngamasentimitha ambalwa ukusuka odongeni, idivayisi enjalo ithole leli gama.

Qaphela! Amaphrojektha endabuko adinga ukufakwa ebangeni elingamamitha amaningana, kuyilapho ama-short-throw angabekwa eduze nodonga.

Lawa ma-projektha avame ukusetshenziswa ezindaweni eziningi zokuhlala lapho abantu befuna ukubalekela ukubuka amamuvi nezinhlelo ze-TV. Ngaphezu kwalokho, ngaphandle kokuthi kulula ukuzifaka, ezincane ngosayizi, lezi projektha akudingeki zixhunywe odongeni zisebenzisa amabakaki. Kwanele ukuba netafula elincane lombhede noma isifuba sabadwebi. Vele uzilungiselele izindleko eziphakeme kakhulu zamaphrojekhtha anjalo okuphonswa okufushane. Amaphrojekhtha amaningi okujikijela amafushane asebenzisa ubuchwepheshe be-DLP kanye nezibani zakudala. Amaphrojektha abiza kakhulu anama-lasers, amalambu e-LED kanye ne-LCD, ubuchwepheshe be-LCoS.

Kunezinhlobo ezimbili ze-DLP [/ caption] Ngakho-ke, lapho uthenga i-projektha, kubalulekile ukuqonda ukuthi isibani esivamile sinikeza isithombe esikhanyayo, kodwa ngokuhamba kwesikhathi singase siqale ukumnyama futhi sihluleke kaningi. Ngaphezu kwalokho, bayakwazi ukufinyelela amandla aphezulu hhayi ngokushesha ngemva kokuvula, kodwa ngemva kwemizuzu engu-1-2. Ngesikhathi esifanayo, i-laser nama-LED ahlala isikhathi eside. Abakwazi ukukhiqiza ukushisa okuningi, futhi futhi abadingi ukufakwa kwezinhlelo zokupholisa ezikhethekile.

Umehluko phakathi kwamaphrojekhtha okujikijela amafushane nawajwayelekile

Amaphrojekhtha okujikijela amafushane ayeklanyelwe ukusetshenziswa ezindaweni ezincane. Isici esiyinhloko yikhono lokunikeza izithombe ezinosayizi ogcwele ebangeni elifushane. Lokhu kufinyelelwa ngokusetshenziswa kwesisombululo se-optical esingajwayelekile, lapho ubude obugxile buqala ukuncipha bube ingxenye yemitha. Izinga lesithombe ngeke lishintshe libe libi kakhulu. Ngaphezu kwalokho, amaphrojektha okujikijela amafushane afakwa ebangeni eliseduze kakhulu nesikrini. Ngebanga elincane ukusuka odongeni, unciphisa isithunzi esithombeni, ngakho-ke ugwema ukukhanya okukhanyayo emehlweni akho. Phakathi komehluko oyinhloko phakathi kweprojektha yokuphonsa iDemo kanye nevamile kukhona:

• kungenzeka ukufakwa eduze odongeni;
• ikhono lokwenqaba ukusetshenziswa kwezintambo ezinde;
• kalula ukufakwa;
• ukungabi khona kwesithunzi.

Ngendlela, uma ungazi ukuthi uzobiza malini ukuthengwa kwe-short-throw projector, ungakwazi ukubala ngokwakho. Ukuze wenze lokhu, vele uye kuwebhusayithi yabakhiqizi abaningi abakhulu be-short-throw projectors, isibonelo, i-Acer bese ufaka yonke imingcele yakho (ibanga lesikrini, kanye nobukhulu bayo obuthandayo). Isibali ngokwaso sizobala izindleko kanye nezinketho zokunikeza. Ngenxa yalokho, umehluko phakathi kokuphonswa okufushane kanye namamodeli ajwayelekile wamaphrojektha ubonakala kakhulu futhi ngoba inketho yokuqala inesilinganiso esikhethekile sokuqagela. Banebanga eliphakeme kakhulu odongeni futhi ububanzi bodonga ngokwalo buzohluka kusuka ku-0.5 kuya ku-1.5 amamitha.

Ubuhle nobubi bamaphrojekhtha okujikijela amafushane

Phakathi kwezinzuzo zokufaka amamodeli we-short-throw ekhaya, singahlukanisa:

• ukukhanya kwesithombe esiphezulu ngisho noma igumbi likhanya kahle;
• ikhono lokubuka umentshisi, imiqhudelwano yezemidlalo, amamuvi esikrinini esikhulu ngamayintshi angaphezu kuka-100.
• ngesofthiwe efakwe ngokukhethekile, umsebenzisi unamandla okubukela imidlalo emine nemiqhudelwano ngesikhathi esisodwa.

Kodwa, njenganoma iyiphi idivayisi, amaphrojektha okujikijela amafushane anenani lokubi:

1. Qhathanisa futhi ubonise ikhwalithi yezithombe ezimnyama. Ngenxa yalokho, ngeke ukwazi ukubuka amafilimu anezigcawu ezimnyama ngemininingwane eminingi.
2. Ikhwalithi yesithombe ephansi kune-projector evamile.
3. Uma singekho isikrini esikhethekile samaphrojektha okujikijela amafushane, isithombe esisodongeni lwendlu sizogezwa kancane futhi siphaphatheke kakhulu.
4. Izindleko eziphezulu zezikrini.
5. Uma i-projektha ibekwe ngokungalingani ebusweni be-dresser noma itafula, kuyoba khona i-fringing ebonakalayo ezungeze izinto.
6. Isipika esisezingeni eliphansi esifakwe kumaphrojekhtha okujikijela amafushane.

Indlela yokukhetha iphrojekthi yokuphonsa iDemo: izincomo ezijwayelekile

Uma, naphezu kwakho konke ukushiyeka kwamamodeli we-projektha we-short-throw, uwakhetha, ngakho-ke kubalulekile ukulandela izincomo zochwepheshe ekuzikhetheni. Ngale ndlela, uzokwazi ukukhetha inketho yeprojektha ezoba sebangeni elingcono kakhulu “lamanani nekhwalithi”. Ngakho-ke, lapho ukhetha i-projektha yokuphonsa iDemo, bese ucabangela amaphuzu alandelayo:

1. Phonsa ibanga . Imele ubuncane/umkhawulo webanga lapho iprojektha ingabekwa khona ukuze kutholwe ikhwalithi yesithombe oyifunayo. Amaphrojekhtha okujikijela okufushane adumile ngoba awadingi isikhala esiningi ukuze abonise isithombe. Isilinganiso esimaphakathi nebanga lesithombe sekhwalithi yimitha elingu-1.
2. Izinga lokukhanya . Inani lama-lumens asebenza njengenkomba eyinhloko yokukhetha ama-projektha okuphonsa okufushane. Khumbula ukuthi izinga lesithombe, ikhono lokulicabangela, lizoxhomeka ekukhanyeni. Ukukhanya okwamukeleka kakhulu kwalolu hlobo lweprojektha kusuka ku-2200 kuya ku-3000 lumens.
3. Imvume . Ikhono lokunquma ukucaca kwesithombe. Kuwumkhuba ukukukala ngendlela efanayo nakuma-TV akudala noma amamonitha ekhompyutha. Khumbula ukuthi amamodeli ashibhile anesinqumo se-HD, kuyilapho enesinqumo somdabu esingu-840 * 840 kuphela (esifanele iDVD).
4. Izinga lokuqhathanisa . Uma uthenga iprojekti yokuphonsa emfushane, qaphela isilinganiso esimhlophe kuya kumnyama. Lapho leli nani liphakeme, i-tint emnyama izogcwala kakhulu. Ngakho-ke, uzothola isithombe esinokujula okuphezulu.
5. Ukuxhumana . Amaphrojektha okuphonsa okufushane kufanele akwazi ukuxhuma kubasizi abaningi efulethini noma ehhovisi. Ngakho-ke, kufanele babe namachweba we-Blu – ray player, ama-consoles wegeyimu yevidiyo. Uma kwenzeka usebenzisa uxhumano olungenantambo, ukukhetha kufanele kwenziwe mayelana namaphrojekhtha asekela i-AirPlay.

Ngakho-ke, lapho ukhetha i-projector ye-short-throw, kubalulekile ukugxila hhayi kuphela kulokho okuthandayo, kodwa futhi uqondiswe yimithetho yokukhetha amadivayisi anjalo. Uma kungenjalo, uzifaka engcupheni yamaphrojekhtha ekhwalithi engeyinhle, okuholela kumamuvi afiphele noma imidlalo kusikrini esikhulu. Okulandelayo, sethula ama-TOP 10 amaphrojekhtha okuphosa amafushane amahle kakhulu afanele ikhaya nehhovisi – ukukala 2022:

I-Top 5 Ultra Short Short Throw 4K Laser Projectors Zikleliswe ngo-2022: https://youtu.be/FRZqMPhPXoA Futhi, khumbula ukuthi iprojektha yokuphosa izohlala ibiza ngaphezu kwe-TV enkulu kakhulu. Uma usulungele ukukhokha inani eliphakeme kakhulu, khona-ke kungcono ukunikeza okuthandayo kumamodeli alula futhi aphezulu. Uma kungenjalo, kuzomele uhlupheke “ngemali ephonswe” ngoba ngeke uyithole into oyifunayo.
