Kungani Ukukhanyisa Kwezemidlalo Kwe-LED Kuduma Kakhulu Ezindaweni Zebhola?
Akukhona nje kuphela ukuthi ukukhanya kwezemidlalo ye-LED kuthuthukiswe ngokushesha eminyakeni emithathu, kodwa futhi sekuphenduke umkhuba eminyakeni emihlanu ezayo. Kusukela ngo-2015, u-30% wezibani zenkundla yebhola e-Europe naseMelika zinezinguquko kusukela kumalambu endabuko e-Metal Halide ukuya ekukhanyeni kwezemidlalo kwe-LED okuguquguqukayo nokusebenza kahle kwesitha. Isibonelo, iqembu lasekhaya iBayern Munich i-Allianz Arena, i-Otkrytiye Arena, i-Aviva Stadium, i-Warsaw National Stadium njalonjalo.
UNobhala we-United States, u-Don Garb, ekwakhiweni kwe-Allianz Arena e-Minnesota, ukhulume ngokukhuphuka kwezinhlelo ze-LED ezindaweni zokukhanyisa ezemidlalo nokuthi kungani izibani eziningi zenkundla yebhola zisebenzisa ubuchwepheshe be-LED.
NgokukaDon-Garber, kunezizathu ezintathu eziyinhloko zokukhetha uhlelo lokukhanyisa ezemidlalo lwe-LED lwezindawo zebhola eziphambili kakhulu: ukuthuthukisa ukusakazwa kwe-TV, ukuthuthukisa isipiliyoni sabalandeli, nokunciphisa izindleko zokusebenza zesikhathi eside.
Ukukhanyisa kwezemidlalo kwe-LED nokulawula kungathuthukisa ukusakazwa kwe-TV.
Ukusakazwa kwethelevishini kudala kunendima ebalulekile ekuthonyeni ukuvela kokukhanya. Kusukela kumaligi ezemidlalo ebhola likanobhutshuzwayo ochwepheshe kuya emidlalweni yebhola lezinyawo yasekolishi, ama-LED athuthukisa ukusakazwa kukamabonakude ngokususa ukudlala kabusha okuhamba kancane kwama-strobes, avamile kumalambu e-metal halide. Ifakwe ukukhanya kwenkundla yebhola lezinyawo ye-LED okuthuthukisiwe, lezi ziqeshana manje zingadlala ngaphandle kokucwayiza ngozimele abangu-20,000 ngesekhondi, ukuze abalandeli bathwebule isekhondi ngalinye lokudlalwa futhi.
Uma ukukhanya kwenkundla yebhola ye-LED kusetshenziselwa ukukhanyisa inkundla yokudlala, isithombe sikhanya kakhulu futhi sicace ku-TV ngoba ukukhanya kwenkundla yebhola lezinyawo ye-LED kungabhalansi phakathi kwemibala efudumele nepholile. Cishe awekho amathunzi, ukuxhopha, noma amachashaza amnyama, ngakho ukunyakaza kuhlala kucacile futhi kungaphazamiseki. Uhlelo lokukhanyisa ezemidlalo lwe-LED lungabuye lulungiswe ngokuya ngendawo yomncintiswano, isikhathi somncintiswano kanye nohlobo lomncintiswano osakazwayo.
Isistimu yokukhanyisa ezemidlalo ye-LED ingathuthukisa ulwazi lwabalandeli emdlalweni.
Abalandeli banokuhlangenwe nakho okungcono kakhulu ngosizo lwesistimu yokukhanyisa ezemidlalo ye-LED, engathuthukisi nje kuphela ukubukwa komdlalo, kodwa futhi yandisa ukubamba iqhaza kwezilaleli. Ukukhanyisa kwezemidlalo kwe-LED kunamandla okukhanyisa ngokushesha, ngakho u-opharetha wezinkundla angakwazi ukulungisa izibani ngesikhathi sekhefu noma phakathi negeyimu.
Uhlelo oluthuthukisiwe lokukhanyisa ezemidlalo lwe-LED lunciphisa izindleko zokusebenza.
Ukuthuthuka kobuchwepheshe bokukhanyisa kwenze izibani zezemidlalo ze-LED zikhange kakhulu kunangaphambili, futhi zithengeke kakhulu kunokukhanyisa kwendabuko okufana nezibani zensimbi ze-halide. Izinkundla zebhola ezinokukhanya kwezemidlalo ze-LED zingonga u-75% kuya ku-85% wengqikithi yezindleko zamandla.
Ngakho-ke, zithini izindleko eziphelele zephrojekthi? Isilinganiso sezindleko zokufakwa kwenkundla isukela ku-$125,000 kuya ku-$400,000, kuyilapho izindleko zokufaka izinkundla zebhola zisukela ku-$800,000 kuya ku-$2 million, kuye ngobukhulu benkundla yebhola, izindawo zokukhanyisa, njll. Njengoba izindleko zamandla nezokulungisa ziyancipha, ukubuya ekutshalweni kwezimali ezinhlelweni zokukhanyisa ezemidlalo ze-LED ngokuvamile kubonakala eminyakeni embalwa.
Izibani zenkundla ye-OAK LED LED zihambisana ngokuqinile nezidingo zemiqhudelwano yezemidlalo yamazwe ngamazwe. Ngokusebenzisa ubuchwepheshe obuphambili kakhulu kanye nezinto ezihamba phambili, izibani zethu zingenza ukukhanya kwezindawo kufinyelele ku-1500-2000 lux nge-flicker ephansi kakhulu. Okwamanje, i-CRI ephezulu ingahlangabezana nezinga lokusakazwa kwe-TV, elingasiza ababukeli kanye nezivakashi ukuba babambe umzuzwana ngamunye enkundleni.
