Ukulunga kokukhanya kwesitalato se-LED
Ndiyakholelwa ukuba abaninzi abantu banamava xa bethatha inqwelomoya: ngobusuku obucacileyo, bejonge ngefestile yenqwelo-moya yabahambi, izixeko ezininzi eziphantsi kwendiza zihlanjwe ngokukhanya okukhanyayo kwe-orange. Oku kungenxa yokuba ukukhanya kukhutshwa ngamawaka ezibane zesodium ezinoxinzelelo oluphezulu. Iingcali zokukhanyisa zathi: "Ukusuka esibhakabhakeni, izixeko ezininzi zifana namabala e-orange."
Nangona kunjalo, ngokuguqulwa kokukhanya kwendlela, ii-LED ziye zatshintsha ngokuthe ngcembe izibane zesodium ezinoxinzelelo oluphezulu kunye neenzuzo zenkonzo yexesha elide kunye nesizukulwana esingcono sokukhanya, kwaye oku kuqalisa ukutshintsha.
Kuqikelelwa ukuba isimbuku sezibane zasesitratweni eUnited States siphakathi kwezigidi ezingama-45 nezingama-55. Phakathi kwazo, izibane ezininzi zesitalato zizibane eziphezulu ze-sodium, kwaye inxalenye encinci yizibane ze-metal halide.
Iingcali zokukhanyisa zathi: "Kwiminyaka emibini edlulileyo, isantya sokwamkelwa kwee-LED sinokuphindaphinda kathathu." "Ngenxa yokusetyenziswa kwezibane ze-LED, umgangatho wokukhanya uphuculwe kakhulu, kwaye ukugcinwa kweendleko kubaluleke kakhulu."
Ukholelwa ukuba izibane ze-LED zineenzuzo ezinkulu ezintathu:
Okokuqala, ukukhanya kwe-LED yesitalato eyenziwe kakuhle kukhupha ukukhanya okucacileyo, okulawulekayo, kunye nokuhle. I-optics eyilwe ngokuchanekileyo kwi-luminaire ye-LED iqinisekisa ukuba ukukhanya kukhanyisa apho kufanele khona, oku kuthetha ukukhanya okungaphantsi kokuchithwa.
Okwesibini, izibane ze-LED zifuna iindleko eziphantsi zokugcinwa kunye nokusetyenziswa kwamandla aphantsi. Kuba uninzi lwezibane zendlela zinomnini kwaye ziqhutywa ziinkampani eziluncedo, ukusetyenziswa kwee-LED kunokunciphisa ukusetyenziswa kwamandla malunga ne-40%. Kwangaxeshanye, eyona nto ibalulekileyo ukonga kukugcina. Ekubeni ukuphuma kwe-lumen yesibane soxinzelelo oluphezulu lwesodium kuncitshisiwe, isibane soxinzelelo oluphezulu lwesodium kufuneka sitshintshwe ubuncinci rhoqo emva kweminyaka emihlanu. Isixhobo kunye nomsebenzi wokutshintsha ibhalbhu enye kunokuxabisa phakathi kwe-$80 ne-$200. Ekubeni ubomi bezibane ze-LED bubude obuphindwe kathathu ukuya kane kune-HID, ixabiso lesondlo esisodwa linokuba likhulu kakhulu.
Okwesithathu, ukukhanya kwezitalato ze-LED ezihombisayo kuyakhula. Ngokuphuculwa kwetheknoloji kunye nokunciphisa iindleko zokuvelisa, abavelisi bokukhanyisa banokunika uluhlu olubanzi lweenketho zokukhanyisa izibane, banokuxelisa uyilo lokukhanyisa izibane zegesi zakudala, njalo njalo, ekhangeleka kakhulu.
Kwiminyaka embalwa edlulileyo, izibane ze-LED zibalwa kuphela inxalenye encinci yemarike yokukhanyisa indlela. Iindleko eziphezulu ze-LED zenza kube nzima kwiidolophu ezininzi ukuguqula xa kuthelekiswa nezibane ze-HID. Kodwa namhlanje, ngokuhambela phambili kwetekhnoloji yokukhanyisa i-LED kunye nokwehla kwamaxabiso, isantya sokwamkelwa kwe-LED siyakhawuleza. Kwixesha elizayo, ukukhanya kwendlela kuya kuba yi-LED.
