Ayini ama-LED futhi asebenza kanjani?
I-LEDimelei-diode ekhanyayo.Imikhiqizo yokukhanyisa kwe-LED ikhiqiza ukukhanya kufika ku-90% ngendlela ephumelelayo kunama-incandescent amalambu.Zisebenza kanjani?Umsinga kagesi udlula ku-microchip, ekhanyisa imithombo emincane yokukhanya esiyibiza ngokuthi ama-LED futhi umphumela uba ukukhanya okubonakalayo.Ukuze uvimbele izinkinga zokusebenza, ama-LED okushisa akhiqizwayo afakwa kusinki wokushisa.
Ukuphila konke kwe-LED Lighting Products
Impilo ewusizo yemikhiqizo yokukhanyisa kwe-LED ichazwa ngokuhlukile kunaleyo yeminye imithombo yokukhanya, efana ne-incandescent noma ukukhanya kwe-compact fluorescent (CFL).Ama-LED ngokuvamile "awashi" noma ahluleke.Kunalokho, bathola 'ukwehla kwe-lumen', lapho ukukhanya kwe-LED kuncipha kancane ngokuhamba kwesikhathi.Ngokungafani nezibani ze-incandescent, "isikhathi sokuphila" se-LED sisungulwa ngokubikezela ukuthi ukuphuma kokukhanya kwehla ngamaphesenti angu-30 nini.
Ama-LED Asetshenziswa Kanjani Ekukhanyeni?
Ama-LED afakwa kuma-bulbs nasezintweni ezisetshenziswayo zokukhanyisa okuvamile.Amancane ngosayizi, ama-LED ahlinzeka ngamathuba ayingqayizivele okuklama.Ezinye izixazululo zesibani se-LED zingase zifane nezibani ezijwayelekile futhi zifane kangcono nokubukeka kwamalambu okukhanya endabuko.Ezinye izibani ze-LED zingaba nama-LED akhelwe ngaphakathi njengomthombo wokukhanya waphakade.Kuphinde kube nezindlela ezixubile lapho kusetshenziswa khona “isibani” esingajwayelekile noma ifomethi yomthombo wokukhanya eshintshwayo futhi yakhelwe ngokukhethekile into ehlukile.Ama-LED anikeza ithuba elihle lokuqamba izinto ezintsha ezicini zokukhanyisa futhi alingane nobubanzi obubanzi bezinhlelo zokusebenza kunobuchwepheshe bokukhanyisa bendabuko.
Ama-LED kanye nokushisa
Ama-LED asebenzisa amasinki okushisa ukuze amunce ukushisa okukhiqizwa yi-LED futhi akulahle endaweni ezungezile.Lokhu kugcina ama-LED angashisi ngokweqile futhi angashi.Ukuphatha okushisayo ngokuvamile kuyisici esisodwa esibaluleke kakhulu ekusebenzeni ngempumelelo kwe-LED phakathi nokuphila kwayo.Uma izinga lokushisa liphezulu lapho ama-LED asebenza khona, ukukhanya kuzokwehla ngokushesha, futhi ukuphila okuwusizo kuzoba mfushane.
Imikhiqizo ye-LED isebenzisa imiklamo ehlukile ye-sink yokushisa ehlukile kanye nezilungiselelo ukuze ilawule ukushisa.Namuhla, ukuthuthuka kwezinto zokwakha kuvumele abakhiqizi ukuthi badizayine izibani ze-LED ezihambisana nokubunjwa nosayizi bama-incandescent endabuko.Kungakhathalekile ukuthi iyini idizayini yokucwilisa ukushisa, yonke imikhiqizo ye-LED ezuze I-ENERGY STAR ihloliwe ukuze kuqinisekiswe ukuthi ilawula kahle ukushisa ukuze ukukhanya okukhiphayo kunakekelwe kahle ekupheleni kwempilo yayo elinganiselwe.
Ingabe ukukhanya kwe-LED kuhluke kanjani kuneminye imithombo yokukhanya, njenge-incandescent ne-Compact Fluorescent (CFL)?
Ukukhanyisa kwe-LED kuhluke ku-incandescent kanye ne-fluorescent ngezindlela eziningana.Uma yakhelwe kahle, ukukhanya kwe-LED kusebenza kahle kakhulu, kuyaguquguquka, futhi kuhlala isikhathi eside.
Ama-LED ayimithombo yokukhanya “eqondile,” okusho ukuthi akhipha ukukhanya endaweni ethile, ngokungafani ne-incandescent ne-CFL, ekhipha ukukhanya nokushisa kuzo zonke izinhlangothi.Lokho kusho ukuthi ama-LED ayakwazi ukusebenzisa ukukhanya namandla ngendlela ephumelela kakhulu kuzinhlelo zokusebenza eziningi.Kodwa-ke, kusho nokuthi ubunjiniyela obuyindida buyadingeka ukukhiqiza isibani se-LED esikhanyisa yonke indawo.
Imibala ye-LED evamile ihlanganisa inhlaka, obomvu, oluhlaza okotshani, noluhlaza okwesibhakabhaka.Ukuze kukhiqizwe ukukhanya okumhlophe, ama-LED anemibala ehlukene ahlanganiswa noma ambozwe ngento ye-phosphor eguqula umbala wokukhanya ekukhanyeni okuvamile “okumhlophe” okusetshenziswa ezindlini.I-Phosphor yinto ephuzi evala amanye ama-LED.Ama-LED anombala asetshenziswa kakhulu njengezibani zesignali namalambu ezinkomba, njengenkinobho yamandla kukhompyutha.
Ku-CFL, amandla kagesi ageleza phakathi kwama-electrode ekugcineni kweshubhu eliqukethe amagesi.Lokhu kusabela kukhiqiza ukukhanya kwe-ultraviolet (UV) nokushisa.Isibani se-UV siguqulwa sibe ukukhanya okubonakalayo lapho sishaya i-phosphor coating ngaphakathi kwe-bulb.
