Yintoni iprojekti yethiyetha yasekhaya, indlela yokukhetha kunye nokudibanisa

Ekhaya, unokubukela iifilimu kungekuphela nje kwiscreen seTV, kodwa nangoncedo lweprojektha. Ukuyisebenzisa, kufuneka ulungiselele isikrini. Umfanekiso uhanjiswa ngesixhobo ngokuqhelekileyo nge-matrix ekhethekileyo esebenza ngokukhanya. Inzuzo ephambili yeeprojekti ezinjalo kukuba zibonelela ngomfanekiso omkhulu kunezikrini ezininzi zikamabonwakude. Esi sixhobo sithumela ulwazi olufunyenwe kumthombo wangaphandle. Isenokuba yi-flash drive, ikhompyutha eqhagamshelwe ngentambo, okanye enye.
Ukusebenzisa iprojektha kunezi nzuzo zilandelayo:

1. Xa ujonga, unokuhlengahlengisa ngokulula ubungakanani besikrini.
2. Ukulula ukudibanisa ngexesha lofakelo.
3. Ubungakanani obuncinci besixhobo.
4. Intuthuzelo yombono onjalo wokubona.
5. Ukungabi naxabiso kwesixhobo xa kuthelekiswa nezinye iinkqubo ezisetyenziselwa ukubukela iimuvi.

Iprojektha ingasetyenziswa njengomboniso wekhompyuter xa iqwalaselwe kakuhle kwaye ifakwe, ngakumbi kwimidlalo yevidiyo.

Nangona kunjalo, xa uthenga iprojektha, kufuneka uqwalasele ukungalungi kwayo:

1. Iprojektha ayifanelekanga ukubonisa iinkqubo zikamabonwakude.
2. Ukuba ukukhanya akwanelanga ukujonga emini, igumbi kufuneka liqale libe nomthunzi.
3. Ukuqinisekisa isandi esikumgangatho ophezulu, kuya kufuneka ukuba usebenzise inkqubo yesithethi.
4. Xa usebenzisa iimodeli zependant, kuyimfuneko ukwenza uhlengahlengiso oluhle ukuze ufumane umfanekiso okumgangatho ophezulu.

Qinisekisa ukuba iprojektha imiswe kakuhle phambi kokusetyenziswa.

Kutheni ufuna iprojektha kwinkqubo yakho yethiyetha yasekhaya

Iiprojektha zingasetyenziselwa ukubukela iimuvi, ukwenza iinkcazo-ntetho, ukubonisa imifanekiso ukuze ujongwe kakuhle. Ekhaya, ungayisebenzisa ukubukela iividiyo kwiscreen esikhulu, kwaye kwezinye iimeko udlale imidlalo yekhompyuter. Njengoko ubuchwephesha buhambela phambili, umgangatho wemifanekiso uya ubangcono, usondela kwinto onokuyifumana kwiscreen sikamabonakude.

Isebenza njani iprojektha yethiyetha yasekhaya?

Kukho iintlobo ngeentlobo zeeprojekti kwimarike, nganye inamandla kunye nobuthathaka bayo ekufuneka iqwalaselwe xa ukhetha. Ukuba siqwalasela iteknoloji yokubonisa ngokubanzi, kubonakala ngathi. Kukho isibane ngaphakathi kwendawo esinika ukukhanya okunamandla ngexesha lomboniso. Njengoko ukukhanya kudlula kwinkqubo ye-optical, ihlukaniswe ibe yimibala emithathu, eluhlaza, obomvu kunye nohlaza okwesibhakabhaka. Emva koko ukukhanya kudlula kwimodyuli, enokuthi ibe yikristale yolwelo okanye ngendlela ye-micromirror matrix. Inokwakheka kwepixel, ekuvumela ukuba wakhe umfanekiso okumgangatho ophezulu.
Iyunithi yolawulo yenzelwe ukusebenza kunye ne-pixel matrix. Ujoliso lomfanekiso lwenziwa ngokusebenzisa ilensi eqokelela imisinga enemibala eyahlukeneyo kunye kwaye ekugqibeleni yenze umfanekiso.

Zeziphi iintlobo zeeprojektha

Zintathu iindidi zeeprojekti ezithengiswayo: i-LCD, i-DLP kunye ne-LED. Emva koko, nganye kuzo iya kuxutyushwa ngokubanzi.

Iiprojektha zeLCD

Ezi zixhobo zezona zifikelelekayo. Kuzo, umfanekiso wenziwa usebenzisa i-crystal matrix engamanzi. Ukuthandwa kwezo projekti kubangelwa ubukhulu becala kwixabiso elifikelelekayo. Le teknoloji iye yaphuhliswa ngakumbi ngendlela ye-3LCD, eyona nto ibalulekileyo kukusetyenziswa kweematrices ezintathu zekristale zamanzi endaweni enye. Ezi modeli zibonelela ngomgangatho ophezulu kodwa zibiza kakhulu.

Iiprojektha zeDLP

Olu hlobo lufana nexabiso kwiiprojekti zeLCD, kodwa lubonelela ngomgangatho ophezulu womfanekiso. Isixhobo esinjalo, sisebenzisa i-matrix yesibuko, sigudisa ukungafezeki komfanekiso kwaye senza ukuba uphile kwaye ukhangeleke. Nangona kunjalo, ezo projektha zine-drawback, ebizwa ngokuqhelekileyo ngokuba yi-iris effect. Oku kuthetha ukuba iiringi zemibala emininzi zinokubumba malunga nezinto ezihamba kwiscreen.

Iiprojekti ze-LED

Izixhobo ezichaphazelekayo zinokusetyenziswa kunye neentlobo ezahlukeneyo zezibane, okwandisa ukhetho. Banikezela umgangatho ophezulu womsebenzi kwaye kwangaxeshanye bagcina amandla.

Indlela yokukhetha iprojektha yethiyetha yasekhaya

Uyilo lweentlobo ezahlukeneyo zezixhobo ezinjalo zinokuhluka kakhulu komnye nomnye. Enye yezona zinto zibalulekileyo zezixhobo ezinjalo sisibane esisetyenzisiweyo. Umgangatho wokukhanyisa ubukhulu becala umisela inqanaba lokuthuthuzela xa ujonga. Izibane zokukhutshwa koxinzelelo oluphezulu zihlala zisetyenziswa njengomthombo wokukhanya. Eyona nto ingathandekiyo kubo kukunxiba ngokukhawuleza. Ngokuqhelekileyo, ukutshintshwa kuyafuneka emva kweeyure ze-2000-4000 zokusebenza. Kwezinye iimeko, izixhobo zabo zinokufikelela kwiiyure ezingama-8000. Enyanisweni, ukutshintshwa kufuneka kwenziwe emva kweminyaka emi-3-4, kwaye kwezinye iimeko rhoqo. Ukwandisa ubomi bezibane ezinjalo, abavelisi baqala ukusebenzisa iteknoloji ye-UHP. Kwezi zibane, ukukhutshwa kusetyenziselwa ukukhanyisa, okwenzeka phakathi kwe-tungsten electrodes. Ezi zibane zixinene kwaye kwangaxeshanye zibonelela ngokuqaqamba okulinganayo nangokurhabaxa. Oku kuqinisekisa umgangatho ophezulu wokunikezelwa kombala. Ezi zibane ziyancipha kancinci kancinci njengoko ziguga. Ubomi benkonzo kaninzi abudluli kwiiyure ezingama-2000. Kwenziwa utshintsho kwisixhobo sabo esiye sabanceda ukuba bahlawulele iingxaki ezikhankanyiweyo. Izibane zeHCX nazo zinobomi obufutshane obunokuthelekiswa nobo bezinye iindidi zezibane zokubonisa. Izibane ze-Metal halide zenza ukukhanya ngokukhupha i-arc yombane eyenziwe kwigesi phantsi koxinzelelo oluphezulu. Bahluke kwizibane ze-UHP ekubunjweni kwegesi apho izongezelelo zenziwa eziphucula umgangatho wemitha ye-spectral kunye negalelo ekufaniseni kwayo. Njengento engalunganga, ukulahleka kancinci komgangatho kuphawulwa njengoko ubomi benkonzo buphelelwa lixesha, obunokufikelela kwi-50%.
Izibane ze-P-VIP zithathwa njengowona mgangatho uphezulu xa kuthelekiswa nezinye iintlobo. Ubomi babo benkonzo yi-6000-8000 iiyure zokusebenza. Isici esibalulekileyo sezibane ezinjalo kukukhanya rhoqo kulo lonke ixesha lokusetyenziswa kwesixhobo sokukhanyisa. Izibane zeXenon zisebenzisa iXenon ecinezelweyo ukugcwalisa ibhalbhu. Izibane zokukhanyisa ezinjalo zinika amandla aphezulu kunye nokukhanya okukhanyayo okukhanyayo. Amandla aphezulu kunye nomgangatho womsebenzi wakhokelela ekubeni zisetyenziswe kwiiprojekti kwii-cinema.
Ukusetyenziswa kwezibane zokukhutshwa kwegesi ngenxa yeentsilelo zazo zendalo ngokuthe ngcembe ziba yinto edlulileyo. Endaweni yoko, ukukhanya kwe-LED ngokuthe ngcembe kuya kuthandwa ngakumbi. Ukusetyenziswa kwee-LED kwenza kube lula ukwandisa ubomi benkonzo yesixhobo, ukwandisa ukuya kwiiyure ezingama-20 eziliwaka. Izibane zokukhanyisa ezinjalo zenza kube lula ukwenza umboniso ophezulu ngaphandle kweemfuno ezikhethekileyo kumphezulu apho umboniso wenziwa khona. Ukungalungi kwezibane ezinjalo akwanelanga ukukhanya okukhanyayo okukhanyayo xa kuthelekiswa nezinye iintlobo zezibane.
Iiprojektha zezixhobo zokukhanyisela ngelaser zinika umgangatho wemifanekiso ogqwesileyo kwithiyetha yasekhaya [/ caption] Izixhobo zokukhanyisa ngelaser zisebenza ngomgangatho ophezulu, zinobomi benkonzo obude, kodwa zibiza kakhulu. Ke ngoko, olona khetho lunomtsalane lunokuthathwa njengokukhanya kwe-hybrid, edibanisa izibonelelo ze-laser kunye ne-LED.

Imiyalelo kunye nomzobo wokudibanisa ithiyetha yasekhaya kwiprojektha

Ukulungiselela ukubukela iifilimu kunye neprojekti, ukufakela kuyadingeka. Ukwenza oku, kuya kufuneka wenze oku kulandelayo:

1. Kufuneka uxhome isikrini apho ifilimu iya kuboniswa khona . Ngeli nqanaba, kubalulekile ukukhetha indawo efanelekileyo kwaye ubeke umgama ochanekileyo kwiprojekti. Kufuneka kukhunjulwe ukuba isikrini akufanele siwele ekukhanyeni kwemithombo yangaphandle – umzekelo, iinkwenkwezi okanye izibane zesitalato. Ukuba kuyimfuneko, kuya kufuneka usebenzise amakhethini amnyama okanye iimfama kwigumbi. Ukuphakama komphetho ongezantsi kufuneka kukhululeke kubaphulaphuli. Ngokuqhelekileyo kuluhlu lwe-62-92 cm.
2. Kufuneka ukhethe indawo yokufaka iprojekti . Ukwenza oku, inokubekwa kwitafile esecaleni kwebhedi, ixhonywe kwisilingi okanye ibekwe phantsi. Xa ufaka, kufuneka uqinisekise umgama kwisikrini esichazwe kumaxwebhu obugcisa. Ngokuqhelekileyo kugqitywa ngokunxulumene ne-diagonal yesikrini. Inyathelo elilandelayo kukunyusa iprojektha. Ukwenza oku, ifakwe kwaye inikwe indawo efanelekileyo yokuphakama.
3. Ngoku kufuneka uqwalasele izixhobo . Okokuqala, kufuneka ulungise kakuhle ugxininiso. Uninzi lweemodeli zinomsebenzi owakhelwe ngaphakathi wohlengahlengiso lwe-elektroniki. Kufuneka ulungelelanise ukucaca kunye nokubukhali, kwaye ukhangele ukuba umfanekiso ulungile kangakanani kwisikrini.

Emva kokwenza zonke izilungiso eziyimfuneko, kufuneka ubone ukuba baya kujongeka njani kwisikrini kwaye bafezekise umgangatho okhoyo. Enye ividiyo malunga nokuqhagamshela iprojektha kunye nophononongo lwe-Epson EH-TW6700 yethiyetha yasekhaya: https://youtu.be/3-wsz82TBCg Ndikunqwenelela ithamsanqa ngokuthenga kwakho.
