Kutheni ukukhanya kwenkundla yebhasikithi kusanda kusebenzisa izibane zezemidlalo ze-LED
Ukukhanya kwezemidlalo kuye kwaphuhliswa ngokukhawuleza kwiminyaka emithathu, kwaye ukukhanya kwezemidlalo ye-LED kuye kwaba yinto ehamba phambili kwiminyaka emihlanu ezayo. Ukusukela ngo-2015, i-30% yokukhanyisa inkundla yebhola yomnyazi eYurophu naseMelika itshintshile ukusuka kwizibane zemveli zentsimbi ye-halide ukuya kwizibane eziguquguqukayo nezisebenzayo zokukhanya kwezemidlalo ze-LED.
Kukho izizathu ezithathu eziphambili zokukhetha inkqubo yokukhanyisa kwezemidlalo ye-LED kwezona nkundla zebhola yomnyazi eziphambili: ukuphucula usasazo lweTV, ukuphucula amava abalandeli, kunye nokunciphisa iindleko zokusebenza kwexesha elide.
Ukukhanya kwezemidlalo ye-LED kunye nokulawula kunokuphucula ukusasazwa kweTV
Ixesha elide, ukusasazwa kweTV kuye kwadlala indima ebalulekileyo ekuphembeleleni ukuguquka kokukhanya. Ukusuka kumdlalo webhola yomnyazi ochwepheshile ukuya kwimidlalo yebhola yomnyazi yasekholejini, ii-LED ziphucula usasazo lukamabonakude ngokususa uphindaphindo oluhamba kancinci lwestrobes, eziqhelekileyo kwizibane zentsimbi.
Xa usebenzisa ukukhanya kwe-LED ukukhanyisa ibala lokudlala, umfanekiso we-TV uya kuqaqamba kwaye ucace ngenxa yokulinganisela phakathi kwemibala efudumele kunye ebandayo yokukhanya kwe-basketball ye-LED. Kukho phantse izithunzi, ukukhanya okanye amabala amnyama, ngoko ke ukunyakaza kuhlala kucacile kwaye kungabonakali. Inkqubo yokukhanyisa ezemidlalo ye-LED inokuhlengahlengiswa isiseko kwibala lomdlalo, ixesha kunye nohlobo lokhuphiswano.
Inkqubo yokukhanyisa ezemidlalo ye-LED inokuphucula amava abalandeli kumdlalo
Ngenkqubo yokukhanyisa kwezemidlalo ye-LED, abalandeli banokuba namava angcono, kungekhona nje ukuphucula ukuzonwabisa komdlalo, kodwa bandise inxaxheba yabaphulaphuli. Izibane zezemidlalo ze-LED zinexesha elisebenzayo, ngoko unokuhlengahlengisa izibane ngexesha lesiqingatha okanye ngexesha lekhefu.
Inkqubo yokukhanya kwezemidlalo ye-LED ephezulu inciphisa iindleko zokusebenza
Ukuqhubela phambili kwitekhnoloji yokukhanyisa kwenze ukuba ukukhanya kwezemidlalo kwe-LED kube nomtsalane ngakumbi kunanini na ngaphambili, kwaye kufikeleleke ngakumbi kunokukhanya kwemveli okufana nezibane zensimbi ze-halide. Amabala ebhola ebhola ekhatywayo anezibane zezemidlalo ze-LED anokonga i-75% ukuya kwi-85% yeendleko zizonke zamandla.
Ke, zithini iindleko zizonke zeprojekthi? Umlinganiselo weendleko zokufakela ibala lemidlalo ususela kwii-$125 000 ukusa kwii-$400 000, ngoxa ukufakwa kwebala lebhola yomnyazi kubiza ukusuka kwii-R800 000 ukusa kwizigidi ezi-2 zeerandi, kuxhomekeka kubukhulu bebala lebhola yomnyazi. Izixhobo zokukhanyisa, njl. Njengoko iindleko zamandla kunye nokugcinwa ziyancipha, ukubuyiswa kotyalo-mali kwiinkqubo zokukhanyisa ezemidlalo ze-LED zidla ngokubonakala kwiminyaka embalwa.
