I-LED (i-Light Emitting Diodes) yeyona nto intsha kunye neyona nto inomdla phambili kwezobuchwepheshe kwishishini lokukhanyisa, elivele kutshanje kwaye lafumana ukuthandwa kwimarike yethu ngenxa yeenzuzo zayo - ukukhanya okusemgangathweni ophezulu, ubomi obude kunye nokunyamezela - Imithombo yokukhanya esekelwe kwi-teknoloji ye-semiconductor P. kwaye i-N inokufikelela kumaxesha angama-20 ubomi benkonzo obude kunezibane ze-fluorescent okanye ze-incandescent.Oku kusivumela ukuba sidwelise ngokulula iingenelo ezininzi zeUkukhanya kwe-LED.

Iidiode ezikhupha ukukhanya ziyinto ebalulekileyo esetyenziswa kwi-electronics iminyaka emininzi, kodwa kutshanje ziye zafumana ukuthandwa kwazo ngenxa yamandla aphezulu e-LED, zinika ukukhanya okunamandla ngokwaneleyo ukuba kusetyenziswe njengeendawo zezibane ze-mercury fluorescent, izibane ze-incandescent okanye ezibizwa ngokuba yi-fluorescent yokonga amandla. iiglowubhu.

Okwangoku, kukho imithombo ye-LED kunye neemodyuli ezikhoyo kwimarike, ezomeleleyo ngokwaneleyo ukuba zisetyenziswe njengezibane zeziseko ezifana nezitalato okanye ukukhanya kwepaki, kunye nokukhanyisa izakhiwo zeofisi, iziteyimu kunye neebhulorho.Zikwangqineka ziluncedo njengomthombo ophambili wokukhanya kwizityalo zemveliso, iindawo zokugcina iimpahla kunye neendawo zeeofisi.

Kwiinkqubo ze-LED ezithatha indawo yokukhanya okuqhelekileyo, izibane ezisetyenziswa ngokuqhelekileyo ziyi-LED SMD kunye ne-COB ebizwa ngokuba yi-Chip LEDs kunye neziphumo ezivela kwi-0.5W ukuya kwi-5W yokukhanya kwendlu kunye ne-10W - 50W yokusetyenziswa kwezoshishino.Ke, ngaba isibane se-LED siluncedo?Ewe, kodwa nayo inemida yayo.Bazintoni?

Izinto ezilungileyo zokukhanyisa kwe-LED

Ubomi benkonzo ende-yenye yeenzuzo ezinkulu zezibane ze-LED.Ii-LED ezisetyenziswe kolu hlobo lokukhanyisa zinomsebenzi ophezulu wokusebenza kwaye ngoko zinokuhamba ukuya kuthi ga kwiminyaka eyi-11 xa kuthelekiswa nezibane zokonga amandla kunye nobomi benkonzo obungaphantsi konyaka.Ngokomzekelo, ii-LED ezisebenza iiyure eziyi-8 ngosuku ziya kuhlala malunga neminyaka engama-20 yobomi benkonzo, kwaye kuphela emva kweli xesha, siya kunyanzeliswa ukuba sitshintshe umthombo wokukhanya omtsha.Ukongezelela, ukucinywa rhoqo kunye nokucima akukho mpembelelo embi kubomi benkonzo, ngelixa kunempembelelo enjalo kwimeko yokukhanya okudala okudala.

Ukusebenza kakuhle - ii-LED okwangoku zingowona mthombo wamandla ombane wokusetyenziswa kwamandla amancinci (umbane) kune-incandescent, i-fluorescent, i-meta halide okanye izibane ze-mercury, ngaphakathi kokukhanya okukhanyayo kwe-80-90% yokukhanyisa kwendabuko.Oku kuthetha ukuba i-80% yamandla anikezelwe kwisixhobo iguqulelwa ekukhanyeni, ngelixa i-20% ilahleka kwaye iguqulelwe kubushushu.Ukusebenza kakuhle kwesibane se-incandescent sikwinqanaba le-5-10% - kuphela ubuninzi bamandla anikezelweyo aguqulwa abe ukukhanya.

Ukuchasana nempembelelo kunye nobushushu - ngokungafaniyo nokukhanya kwendabuko, inzuzo yokukhanyisa i-LED kukuba ayinayo nayiphi na i-filaments okanye i-glass elements, ezithintekayo kakhulu ekubetheni kunye nokubetha.Ngokuqhelekileyo, ekwakhiweni kwezibane eziphezulu ze-LED, iiplastiki eziphezulu kunye neengxenye ze-aluminium zisetyenzisiweyo, ezibangela ukuba ii-LED ziqine kwaye zixhathise ukushisa okuphantsi kunye nokungcangcazela.

Ukutshintshwa kobushushu - ii-LED, xa kuthelekiswa nokukhanya kwendabuko, zivelisa ubushushu obuncinci ngenxa yokusebenza kwazo okuphezulu.Le mveliso yamandla icutshungulwa kakhulu kwaye iguqulelwe ekukhanyeni (90%), evumela uqhagamshelwano oluthe ngqo lomntu kunye nomthombo wokukhanya kwe-LED ngaphandle kokuvezwa ukutshisa nasemva kwexesha elide lomsebenzi wayo kwaye ukongezelela kukhawulelwe ekuvezweni komlilo, enokuthi yenzeke kumagumbi apho
kusetyenziswa ukukhanya kohlobo oludala, olutshisa ukuya kuthi ga kwiidigri ezingamakhulu aliqela.Ngesi sizathu, ukukhanya kwe-LED kulunge ngakumbi kwiimpahla okanye kwizixhobo ezibuthathaka kakhulu kubushushu.

I-Ecology - inzuzo yesibane se-LED ikwayinyaniso yokuba ii-LED azinazo izinto ezinetyhefu ezifana ne-mercury kunye nezinye iintsimbi ezinobungozi kwindalo, ngokungafaniyo nezibane zokulondoloza amandla kwaye zihlaziywa nge-100%, yintoni enceda ukunciphisa i-carbon dioxide. izinto ezikhutshwayo.Ziqulethe iikhompawundi zeekhemikhali ezijongene nombala wokukhanya kwayo (i-phosphor), engenabungozi kwindalo.

Umbala-Kwiteknoloji ye-LED, siyakwazi ukufumana umbala okhanyayo wokukhanya.Imibala esisiseko imhlophe, ibomvu, iluhlaza kunye nohlaza okwesibhakabhaka, kodwa ngeteknoloji yanamhlanje, inkqubela phambili iphezulu kangangokuba sinokufumana nawuphi na umbala.Yonke inkqubo ye-RGB ye-LED inamacandelo amathathu, ngalinye linika umbala owahlukileyo kumbala wephalethi ye-RGB - obomvu, oluhlaza, oluhlaza okwesibhakabhaka.

Iingxaki

Ixabiso - Ukukhanyisa kwe-LED kubiza kakhulu utyalo-mali kunemithombo yokukhanya yendabuko.Nangona kunjalo, kubalulekile ukukhumbula ukuba apha ixesha lokuphila lide kakhulu (ngaphezu kweminyaka eyi-10) kunezibane eziqhelekileyo eziqhelekileyo kwaye ngexesha elifanayo lisebenzisa amaxesha amaninzi ngaphantsi kohlobo oludala lokukhanyisa.Ngexesha lokusebenza komnye umthombo wokukhanya we-LED womgangatho olungileyo, siya kunyanzeleka ukuba sithenge imin.I-5-10 bulbs yohlobo oludala, olungayi kubangela ukonga kwe-wallet yethu.

Ubuzaza bobushushu – Umgangatho wokukhanya kwediode uxhomekeke kakhulu kubushushu bokusebenza obukuyo.Kwiqondo lokushisa eliphezulu kukho utshintsho kwiiparameters zangoku ezidlulayo kwizinto ze-semiconductor, ezinokukhokelela ekutshiseni ngaphandle kwemodyuli ye-LED.Lo mbandela uchaphazela kuphela iindawo kunye nemigangatho evezwe kukunyuka okukhawulezileyo kobushushu okanye ubushushu obuphezulu kakhulu (iintsimbi zokusila).
