Ama-LED aziwa ngokusetshenziswa kwawo okuphansi kwamandla nokukhanya okuphezulu.Ukukhanya nokusetshenziswa kwamandla kungaphezu kuka-60% kwehluke kuma-tungsten bulb endabuko.Kodwa akuwona wonke ama-bulbs acimeka, futhi intengo yama-bulbs azomba eqolo, uzodinga ukuhlola izidingo zakho ngaphambi kokukhetha izibani zakho ze-LED.Lokhu kubaluleke kakhulu uma ushintsha izibani ezindala ngobuchwepheshe obusha be-LED okokuqala ngqa futhi ulindele ukuthi zifiphale.
Ingabe izibani zami ze-Edison ziyacimeka?
Isibani esifiphele isibani esikwazi ukulungisa ukukhanya kokukhanya ngokuvumelana nezimfuneko zekhasimende, ngaleyo ndlela kuthinte ukukhanya kokukhanya kwasendlini futhi kukhiphe izimo zemvelo ezihlukene zasendlini.
Uma uthenge isigxivizo se-LED esiqediwe noma isibani, hlola ukuze uqiniseke ukuthi iphakheji isho ngokuqondile ukuthi iyacimeka.Lokhu kufanele kushiwo encazelweni noma ekucacisweni kobuchwepheshe bokukhanya.Uma usebenzisa i-LED engacishi ku-dimmer uzothola ukucwayiza okuningi futhi ulimaze isibani, ukhawulele ubude bayo bempilo.Uphawu olufana nalolu olungezansi kwesinye isikhathi lusetshenziswa ukukhombisa ukukhanya kufiphale, ngeshwa alukho uphawu oluqondile lomhlaba wonke.
Ngokujwayelekile ukuthi isibani singafiphazwa yini singabonakala ephaketheni lesibani, futhi amalambu acishe acimeke nawo abiza kakhulu kunamalambu angacimeki.Amalambu okukhanya angakwazi ukulungisa ukugqama kokukhanya ngokuvumelana nezidingo zamakhasimende, ngaleyo ndlela athinte ukukhanya kokukhanya kwasendlini futhi akhiphe umkhathi wemvelo ohlukene wasendlini, onge amandla kanye nokunciphisa ukukhishwa kwekhabhoni.Abathengi abaningi ngokwengeziwe bavame ukuthenga izibani ezicimayo.
Isimiso sokufiphalisa isibani se-LED Edison:
Njengomthombo wamanje oqhubekayo, ama-LED ayacimeka ngokwemvelo.Amanje ageleza ebuhlalu besibani se-LED anquma ukuphuma kokukhanya”.Ukukhanya kwabo kungalungiswa kalula ngokulawula amandla akhona ongqimba lwempahla ye-semiconductor enamathiselwe ku-substrate.Ama-LED awafani nemithombo yokukhanya evamile, futhi ukufiphala akuthinti Ukusebenza nempilo yonke yama-LED.Eqinisweni, ukufiphala kunganciphisa izinga lokushisa labo lokusebenza, ngaleyo ndlela kwandise ukuphila kwama-LED.Noma iyiphi idivayisi ye-LED, uma izokwenziwa ibe umthombo wokukhanya esikhundleni noma isibani se-LED, idinga umshayeli ukuze afinyelele ukufiphala.Ngoba ama-LED angumthombo we-DC ene-voltage ephansi, futhi i-LED idinga umshayeli we-electronic ukuze iguqule i-AC ibe yamanje ye-DC esebenzisekayo futhi elungisekayo.Laba bashayeli bahlukaniswe ngezindlela ezintathu zokufiphalisa.
Kumodi ye-pulse width modulation (PWM), i-current ngokusebenzisa i-LED iyavulwa futhi icishwe ngefrikhwensi ephezulu kakhulu, "imvamisa izinkulungwane zezikhathi ngomzuzwana", futhi yamanje nge-LED ilingana nenani elijwayelekile lamanje ngesikhathi umjikelezo wokushintsha kwe-LED.“Ngokunciphisa isikhathi sokusebenza kwe-LED, isilinganiso samanje noma samanje esisebenzayo singancishiswa, ngaleyo ndlela kuncishiswe ukukhanya kwe-LED.Njengemithombo yokukhanya evamile, ama-LED angaphinda afiphazwe ngokunciphisa okuqhubekayo kwamanje (CCR), noma ukufiphala kwe-analog.I-CCR igcina umthombo wokukhanya Kukhona umsinga oqhubekayo, kodwa ukufiphala kufinyelelwa ngokunciphisa ubukhulu bamanje."Ukukhanya okukhiphayo kuhambisana namanje ngedivayisi ye-LED,"
Kokubili i-PWM ne-CCR inezinzuzo kanye nokubi.I-PWM isetshenziswa kabanzi futhi inebanga elibanzi lokufiphala.Ngenxa yokuthi ukufiphaza kwe-PWM kusebenzisa ukuvula nokuvala okusheshayo, kudinga okokusebenza kwe-elekthronikhi eyinkimbinkimbi futhi ebizayo ukuze kukhiqizwe ama-pulses amanje amafrikhwensi aphezulu ngokwanele ukuvimbela amehlo abantu ukuthi angawaboni.ecwayizayo.Indlela yokufiphalisa ye-CCR iphumelela kakhulu futhi ilula, ngoba imishini yokushayela eyidingayo ilula futhi ishibhile.Ngokungafani ne-PWM, i-CCR ayikhiqizi ukuphazamiseka kwe-electromagnetic EMI okubangelwa ukushintsha kwefrikhwensi ephezulu.Nokho, i-CCR ayizilungele izinhlelo zokusebenza lapho imfuneko yokufiphalisa ingaphansi kuka-10%.“Emaza aphansi kakhulu, ama-LED awazange asebenze kahle futhi nokukhanya kwakungazinzile.
Ukunikezwa kwamandla kagesi okulungiswa kabusha okulawulwa yi-Silicon ye-LED kuke kwasetshenziswa ekufiphaliseni amalambu e-incandescent namalambu okonga amandla ngaphambilini, futhi kuyindlela esetshenziswa kakhulu yokufiphalisa i-LED.Isilungisi esilawulwa nge-silicon siwuhlobo lokufiphala ngokomzimba.Umgomo wayo wokusebenza ukukhiqiza i-tangential output voltage waveform ngemuva kokuthi i-waveform ye-voltage yokufaka isikwe yi-engeli conduction.Ukusebenzisa isimiso se-tangential kunganciphisa inani elisebenzayo le-voltage ephumayo, ngaleyo ndlela kunciphise amandla omthwalo ovamile (umthwalo ophikisanayo).I-silicon controlled rectifier dimmers inezinzuzo zokunemba okuphezulu kokulungiswa, ukusebenza kahle okuphezulu, usayizi omncane, isisindo esilula, nesilawuli kude esilula.Ukukhanya okulungisiwe kuthambile futhi kuzinzile, futhi ngeke kube khona ukwenzeka kwe-stroboscopic.ukubusa emakethe.Izinzuzo zokufiphala kwe-rectifier elawulwa yi-Silicon ukusebenza kahle okuphezulu, ukusebenza okuzinzile kanye nezindleko eziphansi zokufiphala.
Ukufiphala kwezigaba ezintathu kwemikhiqizo yethu kusebenzisa amandla okulungisa alawulwa yi-silicon.
Izimo zokusebenzisa amalambu okukhanya acishe abe lula:
Amalambu okukhanya angacimeki asetshenziswa ezigcawini ezihlukahlukene, njengamahhotela, amahholo okudansa, izindawo, amahholo emibukiso nezinye izikhathi ezidinga ukukhanya, ikakhulukazi ngokushintsha inani lomthombo wokukhanya ukuze kulungiswe ukukhanya kokukhanyisa.Manje njengoba umoya uya ukufudumala, indaba yokuthi kuncishiswe kanjani ukusetshenziswa kukagesi ekukhanyiseni nayo isiseduze.Ngenhlanhla, ukuvela kwezibani ze-LED kusindisa amandla amaningi.Kungaba ngcono nakakhulu uma umthetho ungasetshenziswa ukonga ugesi ngempumelelo.Ukuze kufiphale amalambu e-LED, njengamalambu odonga lwasekhaya, amahhovisi, izitolo ezinkulu, izikole, amafekthri nezinye izikhathi kungalungiswa ngokuya ngokukhanyisa okudingekayo, futhi imiphumela yokonga ingafinyelelwa.Uma lezi zikhathi zithathelwa indawo ama-LED ama-bulb alungisekayo, kuzokonga amandla amaningi.
Ukukhanyisa okufiphele kukunikeza ukuguquguquka kokufanisa ukukhanya okuzungezile nomsebenzi wakho.Ungase ufune ukukhanya okukhanyayo uma usebenza kubhuku lokuhlola kodwa ukukhanya okuphumuzayo okufiphele lapho udla kusihlwa.I-Dimming nayo isetshenziswe kakhulu ngaphakathi
izindawo zezohwebo nezimboni.Ukwengeza izibani ezifiphele kunikeza ukuguquguquka kwesikhala sakho sehhovisi futhi kuvumela ukukhanya okulungile kokuncamelayo noma izidingo zabasebenzi bakho.Noma ngabe uhlangana nezivakashi, ubuka i-TV, ulalela umculo, nomndeni wakho, noma ucabanga uwedwa, ungalungisa ukukhanya kwezibani ezihlukene ukuze udale isimo esinethezekile, esithulile, esivumelanayo nesifudumele, kanye nolwazi olujulile lwempilo.Ukukhanya okuthambile kungaletha isimo sengqondo esihle, ukukhanya okuncane nokumnyama kungasiza ukucabanga, ukukhanya okuningi nokukhanya kungenza umkhathi ufudumale.Zonke izidingo eziyinkimbinkimbi zingahlangatshezwana nomsebenzi olula, futhi zidinga kuphela ukulawulwa amaswishi avamile ukuze kulungiswe ukukhanya nobumnyama bezindawo ezihlukene.
