I-LED (Light Emitting Diodes) iyintuthuko entsha futhi ejabulisa kakhulu kwezobuchwepheshe embonini yokukhanyisa, evele kamuva nje futhi yazuza ukuthandwa emakethe yethu ngenxa yezinzuzo zayo - ukukhanya kwekhwalithi ephezulu, impilo ende nokukhuthazela - Imithombo yokukhanya esekelwe kubuchwepheshe be-semiconductor P. futhi i-N inempilo yesevisi ende ephindwe izikhathi ezingu-20 kunezibani ze-fluorescent noma ze-incandescent.Lokhu kusivumela ukuthi sibhale kalula izinzuzo eziningi zeUkukhanyisa kwe-LED.

Ama-diode akhipha ukukhanya ayinto ebalulekile esetshenziswe ku-electronics iminyaka eminingi, kodwa kamuva nje athole ukuthandwa kwawo ngenxa yamandla aphezulu ama-LED, anikeza ukukhanya okuqinile ngokwanele ukuze kusetshenziswe esikhundleni sezibani ze-mercury fluorescent, izibani ze-incandescent noma okuthiwa yi-fluorescent yokonga amandla. ama-bulb.

Njengamanje, kunemithombo ye-LED namamojula atholakalayo emakethe, aqine ngokwanele ukuba asetshenziswe njengezibani zengqalasizinda ezifana nokukhanyisa emgwaqweni noma epaki, ngisho nokukhanyisa kwezakhiwo zamahhovisi, izinkundla zemidlalo namabhuloho.Zibuye zibonakale ziwusizo njengomthombo oyinhloko wokukhanya ezitshalweni zokukhiqiza, izindawo zokugcina izimpahla kanye nezikhala zamahhovisi.

Ezinhlelweni ze-LED ezithatha indawo yokukhanyisa okuvamile, amalambu asetshenziswa kakhulu yi-LED SMD kanye ne-COB ebizwa nangokuthi ama-Chip LEDs anemiphumela esukela ku-0.5W kuya ku-5W yokukhanyisa kwasendlini futhi kusukela ku-10W - 50W ukusetshenziswa kwezimboni.Ngakho-ke, ingabe ukukhanyisa kwe-LED kunezinzuzo zako?Yebo, kodwa futhi inemikhawulo yayo.Bayini?

Izinzuzo zokukhanyisa kwe-LED

Impilo ende yesevisi- ingenye yezinzuzo ezinkulu kakhulu zamalambu e-LED.Ama-LED asetshenziswa kulolu hlobo lokukhanyisa asebenza kahle kakhulu futhi angasebenza iminyaka efika kweyi-11 uma kuqhathaniswa nezibani zokonga amandla anempilo yesevisi engaphansi konyaka.Isibonelo, ama-LED asebenza amahora angu-8 ngosuku azohlala cishe iminyaka engu-20 yempilo yesevisi, futhi ngemva kwalesi sikhathi kuphela, sizophoqeleka ukuthi simiselele umthombo wokukhanya omusha.Ukwengeza, ukuvula nokucisha njalo akunawo umthelela omubi empilweni yesevisi, kuyilapho kunomthelela onjalo esimweni sokukhanya kohlobo oludala.

Ukusebenza kahle - Ama-LED okwamanje angumthombo ongamandla kakhulu wokusebenzisa amandla amancane kakhulu (ugesi) kune-incandescent, fluorescent, meta halide noma amalambu e-mercury, ngaphakathi kokusebenza kahle okukhanyayo okungu-80-90% kokukhanyisa kwendabuko.Lokhu kusho ukuthi u-80% wamandla anikezwa idivayisi aguqulwa abe ukukhanya, kuyilapho u-20% elahlekile futhi aguqulelwe ekushiseni.Ukusebenza kahle kwesibani se-incandescent kusezingeni lika-5-10% - kuphela lelo nani lamandla anikeziwe liguqulwa libe ukukhanya.

Ukumelana nomthelela kanye nezinga lokushisa - ngokungafani nokukhanya kwendabuko, inzuzo yokukhanyisa kwe-LED ukuthi ayiqukethe noma yimiphi imicu noma izakhi zengilazi, ezizwela kakhulu ukushaywa nokushaywa.Ngokuvamile, ekwakhiweni kwezibani zekhwalithi eziphezulu ze-LED, kusetshenziswa amapulasitiki aphezulu kanye nezingxenye ze-aluminium, okubangela ukuthi ama-LED ahlala isikhathi eside futhi amelana nokushisa okuphansi nokudlidliza.

Ukudlulisa ukushisa - Ama-LED, uma kuqhathaniswa nokukhanyisa kwendabuko, akhiqiza ukushisa okuncane ngenxa yokusebenza kwawo okuphezulu.Lokhu kukhiqizwa kwamandla kucutshungulwa kakhulu futhi kuguqulwe kube ukukhanya (90%), okuvumela ukuthintana komuntu ngokuqondile nomthombo wokukhanyisa kwe-LED ngaphandle kokuchayeka ukushisa ngisho nangemva kwesikhathi eside somsebenzi wawo futhi ngaphezu kwalokho kunqunyelwe ukuchayeka emlilweni, okungenzeka emakamelweni lapho
kusetshenziswa ukukhanya kohlobo oludala, okushisa kuze kufike kumadigri angamakhulu amaningana.Ngalesi sizathu, ukukhanya kwe-LED kuvumelana kakhulu nezimpahla noma izinto zokusebenza ezizwela kakhulu izinga lokushisa.

I-Ecology - inzuzo yokukhanyisa kwe-LED futhi iqiniso lokuthi ama-LED awaqukethe izinto ezinobuthi njenge-mercury nezinye izinsimbi eziyingozi emvelweni, ngokungafani nezibani ezonga amandla futhi zikwazi ukuphinda zisetshenziswe ngo-100%, okusiza ukunciphisa i-carbon dioxide. ukukhishwa kwekhabhoni.Ziqukethe izakhi zamakhemikhali ezibhekene nombala wokukhanya kwayo (phosphor), ezingenabungozi emvelweni.

Umbala - Kubuchwepheshe be-LED, siyakwazi ukuthola umbala ngamunye wokukhanya wokukhanya.Imibala eyisisekelo imhlophe, obomvu, oluhlaza okotshani noluhlaza okwesibhakabhaka, kodwa ngobuchwepheshe banamuhla, inqubekelaphambili isithuthuke kakhulu kangangokuthi singathola noma yimuphi umbala.Isistimu ngayinye ye-LED RGB inezigaba ezintathu, ngayinye enikeza umbala ohlukile kumbala wephalethi ye-RGB - obomvu, oluhlaza okotshani, oluhlaza okwesibhakabhaka.

Ukubi

Inani - Ukukhanyisa kwe-LED kuwutshalomali olubiza kakhulu kunemithombo yokukhanya yendabuko.Kodwa-ke, kubalulekile ukukhumbula ukuthi lapha isikhathi sokuphila sikhulu kakhulu (ngaphezu kweminyaka eyi-10) kunezibani ezivamile zokukhanya futhi ngesikhathi esifanayo zisebenzisa amandla ambalwa izikhathi ezimbalwa kunohlobo oludala lokukhanyisa.Ngesikhathi sokusebenza komthombo owodwa wokukhanya we-LED wekhwalithi enhle, sizophoqeleka ukuthi sithenge iminithi.Ama-5-10 ama-bulbs ohlobo oludala, okungeke kubangele ukonga kwesikhwama sethu semali.

Ukuzwela kwezinga lokushisa - Ikhwalithi yokukhanya kwe-diode incike kakhulu kumazinga okushisa asebenzayo.Emazingeni okushisa aphezulu kukhona izinguquko emingceleni yamanje edlula izakhi ze-semiconductor, ezingaholela ekushiseni kwe-module ye-LED.Le nkinga ithinta kuphela izindawo nezindawo ezichayeke ekwenyukeni okusheshayo kwezinga lokushisa noma izinga lokushisa eliphezulu kakhulu (izigayo zensimbi).
