Isifundo sikaNjingalwazi Xiong: Ingakanani imarike yezibane zokuloba ze-LED?Ngaba ingakwazi ukutshintsha ngokupheleleyo isibane sokuloba i-metal halide?
Abanye abantu baqikelela ukuba2000w izibane ze-LED zokuloba ngaphantsi kwamanziimakethi ingaphezulu kwe 100 billion.Olu qikelelo lunethemba kakhulu.Ingaba inkulu kangakanani imakethi yesibane yegolide yaseMarine yelizwe?Andinayo idatha ebanzi malunga nezikhitshane ezilula kwilizwe, ngoko ndinokusebenzisa kuphela endikubonileyo kwamanye amazibuko okuloba njengomzekelo.
Kukho malunga nama-400 amaphenyane okuloba anekhava elikhanyayo kwiDolophu yaseGangqiao, isikhephe ngasinye sibalwa ngomyinge wezibane ezingama-80, kwaye ukukhanya ngakunye kubalwa nge-yuan eyi-1000.Nangona zonke iinqanawa zokuloba kwi-port yokuloba zitshintshe zonke izibane ze-halide zegolide kunye nezibane zokuloba ze-LED, imarike elindelekileyo yezibane zokuloba ze-LED kwidolophu yaseGangqiao iya kuba ngaphantsi kwe-100 yezigidi, kuphela malunga ne-32 yezigidi.Ngaphezu koko, akunakwenzeka ukuba zonke zitshintshwe zizibane zokuloba ze-LED.Ngoko ke, kwiDolophu yaseGangqiao, imarike elindelekileyo yesibane sentlanzi ye-LED ingaphezulu kwe-10 yezigidi.Zingaphi “iidolophu zebhulorho yaseHarbour” ezikhoyo kweli lizwe?I-10 lulandelelwano oluhle lobukhulu.Oko kukuthi, ukukhanya kweentlanzi ze-LED kunokulindelwa kwimarike iyonke ngamakhulu aliqela ezigidi lo myalelo wobukhulu, akukho ntsomi engaphezulu kwe-100 yeebhiliyoni.
Ngokomntu, ndicinga ukuba yinto eqhelekileyo yokuba izibane zentlanzi ze-LED zigcina amandla kunye nokukhuselwa kwendalo, kunyeIzibane zokuloba ze-LEDngokuyinxenye buyisela izibane zegolide ze halide.Kodwa ngaba akuyi kuba lutshintsho olubanzi lwesibane se-halide yegolide?Ngokwam, andicingi njalo iminyaka elishumi.
Masiqale ngezibane zangaphantsi kwamanzi: Nangona kukho abaqolileyoIzibane ze-LED ngaphantsi kwamanzi, iteknoloji ikhulile kuphela kwizibane zokuloba ze-LED ezingaphantsi kwamanzi ukuya kwi-50m ngaphantsi kwamanzi.Ngokuqhelekileyo, inzuzo yesibane se-halide yegolide kwintsimi yesibane esingaphantsi kwamanzi isabaluleke kakhulu: ukukhanya okukhanyayo akuncinci kakhulu kunesibane se-LED, kodwa umthamo unokwenziwa umncinci, oko kuthetha ukuba uxinzelelo lwamanzi luncinci;I-voltage yokusebenza yesibane se-halide yegolide iphezulu, kwaye i-current ejikelezayo ngocingo oluhambelanayo luncinci.Ngokubanzi, kwiisibane samanzi aphantsi kwamanzi,ukulahleka kwentambo yesibane se-metal halide kuncinci kunesibane se-LED esingaphantsi kwamanzi.
Ukukhanya kwamanzi: Ngenxa yesikhokelo esihle sesibane se-LED sokuqokelela iintlanzi, sinokukhanyisa ulwandle ngokufanelekileyo.Ukongeza, ukusebenza okukhanyayo kwe-LED kuphezulu kancinane kunesibane se-halide yegolide, ngoko kukholelwa ngokubanzi ukuba isibane sokuqokelela iintlanzi se-300W LED sinokuthatha indawo ye-1000W yesibane segolide se-halide.Kodwa ngeteknoloji yangoku, izibane zeentlanzi zasemanzini ze-LED kufuneka zixhotyiswe ngama-radiator anzima.Ubunzima besibane se-LED sokuloba emanzini buya kubangela ukuba abalobi bangaze baxhome isibane phezulu kakhulu.Ukuba uxhonywe phezulu kakhulu, umbindi womxhuzulane wephenyane lonke uya kwandiswa, kwaye ukusebenza kokhuseleko kwesikhephe kuya kuncitshiswa.Njengoko kukhankanyiwe ngasentla, ukuphakama kwesibane sixhonywe, indawo ekhanyisiweyo iya kuba nkulu.Isibane se-halogen sifanelekile ukuxhoma kwindawo ephezulu, esinokutsala ngokufanelekileyo ezinye iintlanzi ukusuka kude ukuya kwisikhephe sesibane.
Ukukhanya okuvela kwisibane se-halogen, esingakhanyisi elwandle ngokufanelekileyo, sinokusetyenziselwa ukuvakalisa indawo yokuloba kwiinqanawa zokuloba ezikufutshane.Ngokwentelekiso, isibane se-halide segolide sinoluhlu olubanzi lokubonwayo.
Ngoko ke, ngokumalunga nokukhanya kwe-LED yangoku kunye nobuchwepheshe bayo bokutshatyalaliswa kobushushu, akunakwenzeka ukubuyisela ngokupheleleyo isibane sentlanzi ye-LED kwixesha elizayo.Ukuphakama kwesibane sentlanzi ye-LED kunokufakwa kuncinci, kwaye inokufakwa ecaleni kwenqanawa ukuze ithathe indawoisibane sokuloba i-metal halide.Ukuba isetyenziswe ngokufanelekileyo, ayikwazi nje ukugcina amandla kunye nokunciphisa ukukhutshwa, kodwa nokwandisa ukubamba, ukugcina amandla kunye nokwandisa ingeniso.
Isishwankathelo sesihloko sesithathu: Isibane sokuloba se-LED sinokulindelwa kwimarike yasekhaya iyonke ngamakhulu aliqela ezigidi lo myalelo wobukhulu, akukho ntsomi engaphezu kwe-100 yeebhiliyoni.Isibane sokuloba se-LED asinakukwazi ukutshintsha ngokupheleleyo isibane se-halide segolide phantse iminyaka eli-10, kodwa sinokutshintshwa ngokuyinxenye.Kwiminyaka emi-3-5, kuya kubakho ukuhlalisana kwesibane sokuloba i-LED kunyeisibane se-metal halide, kwaye isabelo semarike yesibane sokuloba i-LED siya kunyuka ngokuthe ngcembe.
