Projectors LED: dib u eegista ah soo saarayaasha oo dib lagu daydo ugu fiican

Tan ah ee suuqa ee qalabka guriga projectors ayaa wax badan ka bedelay. Ma aha kuwa qalabka qaali adeegga raqiisan ma, la isticmaalayo oo ay suurto gal ahayd oo keliya in mugdi ah. Maanta, borojektar ee kuu ogolaanaya in aad si aad u eegto photos iyo videos si fudud u badali TV ama PC shaashadda. Iyo qiimaha lagu daydo in aan taageeri doonnaa xallinta of HD Full, loo siman yahay kharashka telefishannada 40-inch. Waa waqti in ay ka faa'iidaystaan technology this oo noqday milkiilaha faraxsanahay of tiyaatarka guriga leh shaashad si dhab ah toosaa oo leh 300-inch dadab, taas oo ku saabsan waa 7,62 m.

image

Halbeegga ugu weyn ee doorashada waa tayada image of borojektar ah. Laakiin sida uu u dhigi haddii qiimayn aadka loogu baahan yahay dhawr guuldareysto in la sameeyo daydo mashiinka qaali ah ay sabab u tahay la'aanta qol for views?

Tayada image of Saadaasha noqon kartaa argument sida:

• technology imaging,
• cabbirka iyo xallinta ee maxalka furta,
• iska;
• Nuurkii;
• oo dhererkeedu wuxuu focal.

First of dhan, tayada image waxay ku xiran tahay technology qiyaas ah. Hadda waxaa jira saddex teknoolajiyada: DLP, LCD iyo LCOS.

DLP

DLP (SOMA. Digital Light Processing) isticmaalaa shax la beddelo xagal rabitaan ah micromirrors in si toos ah iftiinka gelin gashto diiradda ku. dyeing dogob dhacdaa siyaabo kala duwan. saarayaasha qaar waxay u isticmaalaan si degdeg ah qoqobada cas wheel a. Xaaladdan oo kale, isha arkaa image a xariijimaha monochrome saameyn kara dadka qaar ka mid ah, iyo sidoo kale abuuraa saamaynta qaansoroobaad in ka hortagtaa daawashada a. Qaar kale waxay codsan saddex micromirror soo diyaariyeen midab kasta si gooni gooni ah (technology 3DLP). Projectors isticmaala 3DLP-technology, ka mid ah ugu wanaagsan yihiin, laakiin sidoo kale projectors ugu qaalisan.

LCD

technology LCD (Liquid SOMA. Crystal Display) wuxuu isticmaalayaa saddex furta LCD si ay u sameeyaan qaybaha casaan, cagaar iyo buluug of signal video ah. socodka iftiinka ilayska halide biraha maraa askunmay ama isku xigxiga oo ka mid ah filter a dichroic oo gudbiya ku xigi doonta qaybta reer spectrum iyo muujineysa kale kala qaybiyey saddex qaybood. Mid kasta oo loo soo diray iyada oo ay LCD-furta in la beddelo ka daadanayo iftiin marayay pixel kasta abuuraa image a monochromatic. Xarunta yahay saddex waaxood oo soo saarta qiyaas multi-midab. Waxaa ka mid ah cillado of technology tani waxaa la yiraahdaa image duwan hooseeya (sabab u tahay xaqiiqda ah in crystal waa xaalad u xiran yihiin gudbiya iftiinka, iyo in aan ka badnayn 7% ee bandwidth furta).

LCOS

LCOS (Liquid SOMA. Crystal on Silicon) oo ku salaysan laba hore. Laakiin nuurka ma dhex mari furta crystal dareere ah, iyo baraf ka muuqataa dareeraha on Silicon. Tani waxa ay keentey in images tayo sare leh iyada oo aan ku cillado ee DLP- iyo LCD-technology. Intaas waxaa sii dheer, waxaa suurtagal ah in la kordhiyo mugga pixel iyo gaaro xal image sare. Laakiin projectors qiimaha-LCOS waa mid qaali ah, ilaa hadda soo koobey isticmaalka shineemooyinka iyo hoolalka bandhig weyn.

LED

technology LED (SOMA. Light-emitting Diode, LED) ee abuuraya sanam la isticmaalayo mid ka mid ah farsamooyinka kor ku xusan iyadoo farqiga u ah in isha light halkan waa shax LED. Tani waxay tiraa baahida loo qabo bedelka laambad, isticmaalka awood waa la dhimay. Meyeydaan Balanqaad of safi LED waa 25 kun. Hours. Faa'iida waa ka daadanayo iftiin yar oo aan ka badnayn 2,000 lumens.

borojektar Laser ku qalabeysan yahay koox ka mid ah dioska- laser midabada aasaasiga ah. raqiisan yihiin laser LED projectors hybrid, kaas oo si ay u gaaraan laser diode dhalaalka sare ah lagu daro buluug ah, oo cagaaran, iyo kuwo gaduud uu Kokes ku element dhaadheer.

ogolaanshaha

Qaraarka waxaa lagu go'aamiyaa tirada pixels. Waayo, tayo sare leh image borojektar iyo xuduudaheedu waa in dhigma isha. Waxaad dib u ciyaari karo signal la xal ka duwan, laakiin image waxaa lagu margado doonaa by algorithms riixo ah.

qaraarada Popular waa 1280 x 768 WXGA, 1280 x 720 HD, 1920 x 1080 Full HD, 1920 x 1200 WUXGA.

Nuurkii

daadanayo iska Ifto Yuuna waxaa lagu cabiraa lumens. Projectors la dhalaalka ee 2000-3000 lumens waxaa loo isticmaalaa in fasalada iyo qolalka shirka yar. daadanayo iska Ifto Yuuna ee 3000-4500 lumens haboon hoolalka shirarka waaweyn. dhalaalka image ah haddii ay taasi ku filan, si aanay u daah qolka. lumens A projectors super-dhalaalaya 4500 waxaa loo isticmaalaa at riwaayada, in lagu caweeyo, kaniisadaha iyo sida. D. Cheap iyo projectors qaadi karo yar leh dheecaan iska Ifto Yuuna of 2,000 lumens baahan madoobaato guud ahaan ama qayb ka mid ah qolka yar.

iska

Ratio of luminance ugu sareeya iyo ugu hooseeya ee shaashadda waxaa lagu magacaabaa ratio duwan ee borojektar ah. Tusaale ahaan, ka duwan ee 10,000: 1 muujinayo in ay dhalaalka cad ka badan dhalaalka madow 10 000 jeer. Marka la barbardhigo qolka nezatemnonnom barbareeyay by ilo iftiin dibadda iyo xadka liita ee ka daadanayo iska Ifto Yuuna muhiimada borojektar ah.

gashto

projectors Video lenses waxaa lagu wareejin karaa isbedel Buuggan ama si toos ah oo dhererkiisu focal. loo baahan yahay in la beddelo size image oo aan dhaqaaqin borojektar laftiisa.

Sidoo kale, siku waxa lagu gartaa ratio ee meel fog ka soo shaashadda si ay size. Projectors waa muddo dheer diirada (2-8: 1) Heerka (1-2) iyo a-diiradda gaaban (in ka yar 1).

Features LED-projectors

• isticmaalka gudaha u baahan tahay ka fujiyaan for macaamiloon ugu badnaan iyo iftiin ee image ah.
• Qalabka la dheecaan iska Ifto Yuuna 300 lumens loo xisaabiyaa on width ah ee 0.2 m screen, iyo in ka badan 500 oo lumens - 3 m.
• Ku haboon tiyaatarka guriga mobile. Ma aha bedelka buuxda projectors iyo laambadaheedii halide biraha.
• Qaadashada waxaa lagu gaarayaa by joogitaanka sahayda ay xoog u dibadda, awood wireless.
• Lagu daydo oo leh dheecaan iska Ifto Yuuna sare oo heer sare buuqa, si ku haboon loo isticmaalo goobaha dadweynaha.
• isticmaalka Awooda waa ay yar tahay.

LED borojektar: muuqaalka guud ee lagu daydo oo caan ah

Maalin kasta ee suuqa, moodooyinka cusub ee projectors, isha iftiin, taas oo uu Kokes waxaa loo isticmaalaa. Kuwa soo socda ayaa kaliya LED-projectors, taas oo u eegay ahaayeen wanaagsan. Sidaas daraaddeed ha ka bilowno.

Mini LED-borojektar ViewSonic PLED-W800 - qalab jeebka loogu tala galay bandhig ganacsi, sida ay yidhaahdaan, "on Daqsi". Laakiin, sida ay macaamiisha, wax soo saarka ee iftiinka u ogolaanaya in uu guriga ku isticmaalo.

Shirkadda ViewSonic California ku takhasusay qalabka qiyaas ka 80s soo daahay. Dhowr sano ka hor waxa uu noqday horyaal ah line cusub ee mini-LED-projectors leh model PLED-W500. lagu daydo oo hadda ku jira W200, W600 iyo W800.
