Maalmahan, inta badan tiyaatarada filimada weli waxay qaataan tignoolajiyada saadaalinta.Waxay ka dhigan tahay in sawirka lagu saadaaliyay daahyada cad ee daahyada by projector.Sida muraayadda yar yar ee LED-ku dhashay, waxay bilaabataa in loo isticmaalo gudaha gudaha, oo si tartiib tartiib ah u beddelo tignoolajiyada saadaalinta.Sidaa darteed, booska suuqa ee suurtogalka ah ee bandhigyada LED-yada yaryar waa mid aad u weyn.
Inkasta oo iftiinka sare uu yahay mid ka mid ah sifooyinka muuqda ee shaashadda LED-ka, guud ahaan wuxuu qaataa mabda'a is-iftiinka, pixel kasta wuxuu soo saaraa iftiin si madax-bannaan, sidaas darteed saameynta soo-bandhigidda waa isku mid ee jagooyinka kala duwan ee shaashadda.Maxaa ka sii badan, shaashadda LED-ku waxay qabataa dhammaan asalka shaashadda madow, taas oo ka duwan tignoolajiyada saadaalinta dhaqameed.
Sida caadiga ah, inta badan qalabka dib-u-ciyaarista ee lagu isticmaalo tiyaatarada dhaqameedku waa tignoolajiyada saadaalinta.Sababtoo ah nidaamka saadaalintu wuxuu isticmaalaa mabda'a sawir-qaadista, masaafada u dhaxaysa iftiinka la saadaaliyay iyo bartamaha shaashadda waa ka duwan yahay, booska saddexda midab ee midabka aasaasiga ah ee tuubada saadaasha waa ka duwan yahay.Habkani waxa uu keenayaa in sawirka la saadaaliyay ay fududahay in la jiro oo leh qadar yar oo pixel defocus ah iyo gees midab leh.Intaa waxaa dheer, shaashadda filimku waxay isticmaashaa daah cad, taas oo yareyn doonta farqiga sawirka.
Faa'iidooyinka iyo khasaaraha ee projectors LED
Faa'iidooyinkaFaa'iidada ugu weyn ee projectors LED waa nolosha laambadahooda iyo wax soo saarka kulaylka yar.Nalalka LED-yadu waxay ugu yaraan 10 jeer ka dheer yihiin nalalka caadiga ah ee projector-ka.Mashruucyaal badan oo LED ah ayaa socon kara 10,000 saacadood ama ka badan.Maaddaama laambaddu ay sii jirto nolosha projector-ka, uma baahnid inaad ka walwasho iibsashada nalal cusub.
Sababtoo ah LED-yadu aad bay u yar yihiin oo waxay u baahan yihiin oo kaliya inay qabtaan semi- conduct, waxay ku shaqeeyaan heerkul aad u hooseeya.Tani waxay ka dhigan tahay inaysan u baahnayn socodka hawada badan, taasoo u oggolaanaysa inay noqdaan kuwo aamusan oo is haysta.
Si aad u dhaqso badan u bilow oo xidho wakhtiyada maadaama aan kululayn ama qaboojin loo baahnayn.Mashruucyada LED-yada ayaa sidoo kale aad uga aamusan kuwa isticmaala nalalka caadiga ah.
Qasaarooyinka:Khasaaraha ugu weyn ee mashruucyada LED waa dhalaalkooda.Najiyeyaasha LED-yada intooda badani waxay ku badan yihiin qiyaastii 3,000 - 3,500 lumens.
LED maaha tignoolajiyada bandhiga.Taas beddelkeeda waxay tixraac u tahay isha iftiinka ee la isticmaalo.
