Yini eyenza izibani ze-LED zikhetheke?

Izibani ze-LED ziye zanda kakhulu eminyakeni yamuva ngenxa yokusebenza kahle kwamandla, impilo ende, nokukhanya okukhanyayo. Kodwa yini ngempela eyenza izibani ze-LED zikhetheke kangaka? Kulesi sihloko, sizocubungula izici ezihlukahlukene kanye nezinzuzo zamalambu e-LED, futhi sihlole ukuthi yini ewahlukanisa nezinketho zokukhanyisa zendabuko. Kusukela kubuchwepheshe babo obuyingqayizivele kuya ezinzuzweni zabo zemvelo, izibani ze-LED zinokuningi okunikezwayo. Ngakho-ke ake sibhekisise ukuthi yini eyenza izibani ze-LED zikhetheke.

Ukusebenza Kwamandla

Enye yezinto ezibalulekile ezenza izibani ze-LED zikhetheke ukusebenza kahle kwazo okukhethekile. Ngokungafani nezibani zendabuko ze-incandescent noma ze-fluorescent, izibani ze-LED ziguqula iphesenti eliphezulu likagesi eliwusebenzisayo libe ukukhanya, kunokushisa. Lokhu kusho ukuthi izibani ze-LED zidinga amandla amancane kakhulu ukuze zikhiqize inani elifanayo lokukhanya, okuzenza zibe inketho yokukhanyisa eqhubekayo futhi engabizi.

Izibani ze-LED zifinyelela leli zinga eliphezulu lokusebenza kahle kwamandla ngokusebenzisa kwazo i-semiconductor ukukhiqiza ukukhanya. Lapho amandla kagesi edlula ezintweni ze-semiconductor, ashukumisa ukunyakaza kwama-electron, okwenza kube ukukhanya. Le nqubo iphumelela kakhulu kunokushisisa intambo noma i-ionization yegesi esetshenziswa ekukhanyisweni kwendabuko, okuholela ekumoshweni kwamandla amancane kanye nezindleko zikagesi eziphansi.

Ngokungeziwe ekusebenziseni kwabo amandla okuncishisiwe, izibani ze-LED nazo zinesikhathi eside sokuphila uma kuqhathaniswa nezinketho zokukhanyisa zendabuko. Lokhu kusho ukuthi awagcini nje ngokudla amandla amancane, kodwa futhi ahlala isikhathi eside, anciphisa imvamisa yokushintshwa futhi afake isandla ekulondolozeni amandla kanye nezindleko.

Ukugqama kanye Nezinketho Zombala

Esinye isici esenza amalambu e-LED akhethekile wukuguquguquka kwawo ekuhlinzekeni ububanzi bamazinga okukhanya nezinketho zombala. Izibani ze-LED zitholakala ngamaleveli ahlukahlukene okukhanya, okuvumela abasebenzisi ukuthi bakhethe ukushuba kokukhanya okufanela kangcono izidingo zabo. Noma ngabe okokukhanyisa kwe-ambient, ukukhanyisa umsebenzi, noma ukukhanya kwe-accent, izibani ze-LED zingenziwa ngendlela oyifisayo ukuze zinikeze izinga eliphelele lokukhanya kunoma yisiphi isikhala.

Ngokungeziwe ekukhanyeni, izibani ze-LED zinikeza nohlu lwezinketho zemibala, kusukela kokumhlophe okupholile kuya kokumhlophe okufudumele, ngisho nama-LED anombala. Lokhu kuguquguquka kombala kuvumela imiklamo yokukhanyisa yokudala kanye nekhono lokudala i-atmosphere ehlukene ngaphakathi kwesikhala. Kungakhathaliseki ukuthi kwakha indawo efudumele noma ekhangayo endaweni yokuhlala noma kusetshenziswa ama-LED anemibala ngezinjongo zokuhlobisa noma zokuthengisa, izibani ze-LED zinikeza izinketho eziningi ukuze zivumelane nezintandokazi zokukhanyisa ezihlukahlukene kanye nobuhle bedizayini.

Ngokuthuthuka kobuchwepheshe be-LED, manje sekungenzeka ukuthi uthole izibani ze-LED ezikwazi ukukhiqiza imibala ehlukahlukene, enikeza amathuba amaningi nakakhulu emiklamo yokukhanyisa enamandla nenamandla.

Ukukhanya Okusheshayo

Amalambu e-LED agqama ngokukwazi kwawo ukukhanyisa ngokushesha ngaphandle kwanoma yisiphi isikhathi sokufudumala. Ngokungafani nezinye izinketho zokukhanyisa zendabuko, njengezibani ze-compact fluorescent (CFLs), ezingathatha imizuzwana embalwa ukufinyelela ukukhanya okugcwele, izibani ze-LED zinikeza ukukhanya okusheshayo ngokushesha nje lapho zikhanyiswa. Lokhu kukhanyisa okusheshayo akulula nje kuphela kodwa futhi kuthuthukisa ukuphepha ezindaweni lapho ukubonakala ngokushesha kubalulekile, njengezitebhisi, izindawo zokupaka, noma izindawo zokuphuma eziphuthumayo.

Ikhono lezibani ze-LED ukuze zifinyelele ngokushesha ekukhanyeni okugcwele futhi lizenza zilungele izinhlelo zokusebenza lapho ukucisha nokucishwa njalo kuyadingeka, njengoba akuthinti ukuphila kwazo noma ukusebenza kwazo. Lesi sikhathi sokuphendula esisheshayo, sihlanganiswe nokusebenza kahle kwamandla, kwenza izibani ze-LED zibe yisinqumo esiwusizo nesithembekile sezinhlelo zokusebenza zokukhanyisa ezihlukahlukene, kusukela ekukhanyisweni kwezindawo zokuhlala nezokuhweba kuya ekukhanyeni kwezimoto nangaphandle.

Ukuqina Nokugcinwa Okuphansi

Izibani ze-LED ziyaziwa ngokuhlala kwazo kanye nezidingo eziphansi zokugcinwa kwazo, okuzenza zibe isisombululo sokukhanyisa esithembekile nesihlala isikhathi eside. Ngokungafani nezibani zendabuko ezenziwe ngezinto ezibuthakathaka njengengilazi noma imicu, izibani ze-LED zakhiwa kusetshenziswa izinto eziqinile ze-semiconductor ezimelana kakhulu nokushaqeka, ukudlidliza, nomthelela wangaphandle. Lokhu kwakhiwa okuqinile kwenza izibani ze-LED zingangenwa kalula ukulimala nokuphuka, okuzenza zikufanelekele ukusetshenziswa ezindaweni eziyinselele noma izinhlelo zokusebenza lapho ukuqina kubalulekile.

Ngaphezu kwalokho, izibani ze-LED ziphila isikhathi eside kakhulu uma ziqhathaniswa nezinketho zokukhanyisa zendabuko. Ngesilinganiso sokuphila samahora angu-25,000 kuya kwangu-50,000, izibani ze-LED zihlala isikhathi eside ngokuphindwe kaningi kunezibani ze-incandescent noma ze-fluorescent, zinciphisa imvamisa yokushintshwa kanye nezindleko zokulungisa ezihambisanayo. Le nkathi yokuphila ende ayigcini nje ngokusindisa imali kodwa futhi inciphisa umthelela wemvelo wamalambu okukhanya alahliwe, okunikela ezisombululweni zokukhanyisa ezisimeme nezivumelana nemvelo.

Ukuqina kanye nezidingo zokunakekelwa okuphansi kwezibani ze-LED zizenza zibe yinketho ekhangayo kuhlelo olubanzi lwezinhlelo zokusebenza, okuhlanganisa ukukhanya kwangaphandle, ukukhanya kwemboni, nezinye izindawo lapho ukwethembeka nokuphila isikhathi eside kubaluleke kakhulu.

Izinzuzo Zemvelo

Ngokungeziwe ekusebenzeni kahle kwazo kwamandla nokuphila isikhathi eside, izibani ze-LED zinikeza izinzuzo ezimbalwa zemvelo ezizenza zibe inketho yokukhanyisa ekhethekile futhi eqhubekayo. Izibani ze-LED zisebenzisa amandla amancane kunezinketho zokukhanyisa zendabuko, zinciphisa ukukhishwa kwekhabhoni kanye nomthelela jikelele wemvelo ohambisana nokukhiqizwa kukagesi. Lokhu kwenza amalambu e-LED abe yinketho evumelana nemvelo kulabo abafuna ukunciphisa indawo yabo yekhabhoni futhi banikele ekusaseni eliluhlaza nelizinzile.

Ngaphezu kwalokho, izibani ze-LED aziqukethe izinto eziyingozi njenge-mercury, evame ukutholakala kumalambu e-fluorescent. Lokhu kwenza izibani ze-LED ziphephe ukusetshenziswa futhi kulula ukuzilahla ekupheleni kwesikhathi sabo sokuphila, njengoba zingabeki ubungozi obufanayo bemvelo njengezinketho zokukhanyisa ezivamile. Amalambu e-LED aphinde akhiphe ukushisa okuncane, ehlise umthwalo kumasistimu okushisa umoya futhi abe negalelo ekongeni amandla kanye nokusimama kwemvelo.

Ngokusebenza kahle kwawo okukhethekile kwamandla, ubude besikhathi eside, kanye nomthelela omncane kwezemvelo, izibani ze-LED zinikeza isixazululo esicindezelayo kulabo abafuna ukunciphisa ukusetshenziswa kwabo kwamandla, ukonga imali, kanye nokunciphisa indawo yabo yemvelo.

Isiphetho

Sengiphetha, izibani ze-LED zikhethekile ngenxa yezizathu ezihlukahlukene, kusukela ekusebenzeni kahle kwawo kwamandla kanye nempilo ende kuya ezinhlobonhlobo zazo ekukhanyeni nasekukhetheni imibala. Ukukhanya kwazo okusheshayo, ukuqina, kanye nezidingo zokunakekelwa okuphansi, kanye nezinzuzo zazo zemvelo, ziqhubeka zifaka isandla ekuthandeni kwazo njengenketho yokukhanyisa ephezulu. Njengoba ubuchwepheshe be-LED buqhubeka buthuthuka, amandla ezixazululo zokukhanyisa ezintsha neziqhubekayo azokhula kuphela, anikeze izizathu ezengeziwe zokucabangela izibani ze-LED zezinhlelo zokusebenza zokukhanyisa ezihlukahlukene.

Kungakhathaliseki ukuthi okokuhlala, ezohwebo, noma ukusetshenziswa kwezimboni, izibani ze-LED ziyinketho ehlakaniphile futhi eqaphela imvelo enikeza izinzuzo eziningi kunezinketho zokukhanyisa ezivamile. Ngokusebenza kwawo okukhethekile, ukonga izindleko, nomthelela omuhle kwezemvelo, izibani ze-LED zigqama ngempela njengesixazululo sokukhanyisa esikhethekile nesibalulekile samanje nekusasa.
