Isifundo sikaSolwazi Xiong: Ingakanani imakethe yezibani zokudoba ze-LED? Ingabe ingakwazi ukufaka ngokugcwele isibani sokudoba se-metal halide?
Abanye abantu balinganisela ukuthi2000w LED izibani zokudoba ngaphansi kwamanziimakethe ingaphezu kwezigidigidi eziyi-100. Lesi silinganiso sinethemba elikhulu. Ingakanani imakethe yesibani se-Marine gold halide kazwelonke? Anginayo idatha egcwele ngezikebhe ezincane ezweni, ngakho-ke ngingasebenzisa engikubone kwezinye izikebhe zokudoba njengesibonelo.
Kunezikebhe zokudoba ezingaba ngu-400 ezinekhava ekhanyayo eDolobheni lase-Gangqiao, isikebhe ngasinye sibalwa ngesilinganiso sezibani ezingama-80, futhi ukukhanya ngakunye kubalwa ngamayuan ayi-1000. Ngisho noma zonke izikebhe zokudoba echwebeni lokudoba zishintsha zonke izibani ze-halide zegolide ngezibani zokudoba ze-LED, imakethe ephelele elindelwe yezibani zokudoba ze-LED eGangqiao Town izoba ngaphansi kwezigidi ezingu-100, cishe izigidi ezingu-32 kuphela. Ngaphezu kwalokho, akunakwenzeka ukuthi zonke zishintshwe izibani zokudoba ze-LED. Ngakho-ke, eGangqiao Town, imakethe elindelwe yesibani sezinhlanzi ze-LED ingaphezu kwezigidi ezingu-10. Mangaki “amadolobha amabhuloho echweba” akhona ezweni? I-10 iyindlela enhle yobukhulu. Okusho ukuthi, ukukhanya kwezinhlanzi ze-LED kungalindelwa emakethe isiyonke kuyizigidi ezingamakhulu amaningana lolu hlelo lobukhulu, akukho nganekwane engaphezu kwezigidigidi eziyi-100.
Ngokwami, ngicabanga ukuthi kuwumkhuba ojwayelekile wokuthi izibani zezinhlanzi ze-LED zonga amandla nokuvikelwa kwemvelo, futhiIzibani zokudoba ze-LEDshintsha kancane izibani ze-halide zegolide. Kodwa ngeke yini kube ukushintshwa okuphelele kwesibani se-halide segolide? Ngokwami, angicabangi kanjalo okungenani iminyaka eyishumi.
Ake siqale ngamalambu angaphansi kwamanzi: Nakuba kukhona asebekhulileAmalambu angaphansi kwamanzi e-LED, ubuchwepheshe buvuthwe kuphela ezibani zokudoba ze-LED ezingaphansi kwamanzi ezifika ku-50m ngaphansi kwamanzi. Ngokuvamile, inzuzo yesibani se-halide yegolide emkhakheni wesibani esingaphansi kwamanzi isaphawuleka kakhulu: ukusebenza kahle okukhanyayo akuncane kakhulu kunesibani se-LED, kodwa umthamo ungenziwa ube mncane, okusho ukuthi ukucindezela kwamanzi kuncane; I-voltage yokusebenza yesibani segolide se-halide iphezulu, futhi yamanje egeleza ngocingo oluhambisanayo incane. Ngokuvamile, ku-isibani esingaphansi kwamanzi ajulile,ukulahlekelwa kwekhebula kwesibani se-metal halide kuncane kunesibani esingaphansi kwamanzi se-LED.
Ukukhanya kwamanzi: Ngenxa yokuqondisa okuhle kwesibani se-LED esiqoqa izinhlanzi, singakhanyisa ulwandle ngokuphumelelayo. Ngaphezu kwalokho, ukusebenza kahle okukhanyayo kwe-LED kuphakeme kancane kunesibani se-halide segolide, ngakho-ke kukholelwa ukuthi isibani sokuqoqa izinhlanzi esingu-300W LED singangena esikhundleni sesibani segolide se-halide esingu-1000W. Kodwa ngobuchwepheshe bamanje, izibani zezinhlanzi zasemanzini ze-LED kumele zifakwe ama-radiator anzima. Isisindo esinzima sesibani se-LED sokudoba emanzini sizobangela abadobi ukuthi bangalinge balengise isibani phezulu kakhulu. Uma ilenga phezulu kakhulu, isikhungo samandla adonsela phansi kuso sonke isikebhe sizokwandiswa, futhi ukusebenza kokuphepha kwesikebhe kuzoncipha. Njengoba kushiwo ngenhla, ukuphakama kwesibani kulenga, indawo ekhanyisiwe izoba nkulu. Isibani se-halogen sifanelekile ukulenga endaweni ephakeme, engaheha ngokuphumelelayo ezinye izinhlanzi ezisuka kude ukuya esikebheni sesibani.
Ukukhanya kwesibani se-halogen, okungakhanyi kahle olwandle, kungasetshenziswa ukumemezela indawo yokudoba ezikebheni zokudoba eziseduze. Uma kuqhathaniswa, isibani segolide se-halide sinohlu olubanzi olubonakalayo.
Ngakho-ke, mayelana nokukhanya kwe-LED yamanje kanye nobuchwepheshe bayo bokukhipha ukushisa, akunakwenzeka ukufaka ngokugcwele isibani sezinhlanzi ze-LED esikhathini esizayo esiseduze. Ukuphakama kwesibani sezinhlanzi ze-LED kungafakwa kuncane kakhulu, futhi kungafakwa eceleni komkhumbi ukuze kuthathelwe indawo ingxenye yeisibani sokudoba se-metal halide. Uma isetshenziswe kahle, ayikwazi nje ukonga amandla futhi inciphise ukukhishwa, kodwa ikhulise nokubamba, yonga amandla futhi yandise imali engenayo.
Isifinyezo sesihloko sesithathu: LED set isibani sokudoba kungalindelwa ingqikithi emakethe yasekhaya makhulu ambalwa million lokhu oda of magnitude, akukho legend kuka 100 billion. Isibani sokudoba se-LED asikwazi ukufaka ngokuphelele isibani se-halide segolide cishe eminyakeni eyi-10, kodwa singashintshwa ngokwengxenye. Eminyakeni engu-3-5, kuyoba khona ukuhlalisana kwesibani sokudoba se-LED kanyeisibani se-metal halide, futhi isabelo semakethe sesibani sokudoba se-LED sizokhula kancane kancane.
