Indlela yokukhetha isibani se-LED? Izici, izinhlobo kanye nabakhiqizi

Umuntu ngamunye, esefikile esitolo, ufuna ukuthenga imishini ephakeme kakhulu ezosebenza isikhathi eside. Ngakho-ke, lo mbuzo uvela: kanjani ukukhetha isibani se-LED? Njengomthetho, abantu bathembele ekubuyekezweni kwi-intanethi. Kodwa akuzona njalo lezi zibani ezisesitolo. Bangashintshwa yizinye izinhlobo zezinsiza. Ukuxazulula le nkinga, kubalulekile ukutadisha izici zobuchwepheshe zezingxenye. Ngamunye wabo angatholakala kuphakheji. Ake sicabangele lezi zici ngokuningiliziwe.

I-Plinth

Kuze kube manje, izibani eziningi ze-LED zitholakala kumiklamo ehlukene.

Zonke izinhlobo zezibani ze-LED zinezinhlamvu ezihlukile, ezibonisa ukuthi zingasetshenziswa kuphi. Isibonelo, igama elithi E40 libonisa ukuthi lisetshenziselwa ukukhanyisa amakamelo amakhulu noma izitaladi.

Ukusetshenziswa kwamandla

Idlala indima ebalulekile ekukhanyeni igumbi. Ukuphakama kwamandla, i-brightness igumbi lizoba. Noma kunjalo, lesi sibonakaliso sithinteka ngezinga lokukhanya kwe-flow flux. Wonke amadivaysi alolu hlobo akhiqizwa ngamandla ka-3 kuya ku-25 V. Ukuze igumbi lokuphumula, izibani ezikhanyisayo ze-LED ziyi-12 V.

Umthombo wamanje wedivayisi

Njengoba ukuhlinzekwa kusebenza njengamanje okuhambayo nokuqondile. Uma usebenzisa njalo, ngalezi zinhloso, izibani ze-LED ezihamba phambili ziyi-volts ayi-12. Noma kunjalo, isimo sokugunyazwa sokusebenza kwabo ukusetshenziswa kwabashayeli abakhethekile. Yizinhlelo zabo ezifaka izibani. Amashayeli aphinde axhumane nomkhaya we-AC.

Kubalulekile! Ngaphambi kokuthenga isibani, udinga ukuthola ukuthi yikuphi okuzosetshenziswa manje - okushintshaniswa noma okuhlala njalo.

Uma ukhetho lungalungile, i-LED ngeke isebenze noma ishise okokuqala ivuliwe. Uma umshayeli efakwe isibani se-LED, ivumela kalula ukuqhuma kwe-voltage. Kulokhu, kuzosebenza kumodi efanayo.

Flux Luminous

Lona uphawu oluphawulekayo lobuchwepheshe. Kuncike ekukhanyeni kokukhanya nokusebenza kahle. Iyunithi yokulinganisa yi-lumen. Kubonisa isilinganiso samandla emisebe kuya emotheni esetshenzisiwe, ngaleyo ndlela sibonise ukusebenza kwayo. Isibonelo, emikhiqizweni evamile lesi sibalo singama-15 Lm / W, kanti nemikhiqizo ye-LED iyi-90 Lm / W.. Kungaphetha ngokuthi i-watt ngayinye yesibani se- diode ikhishwa izikhathi eziphindwe izikhathi eziyishumi kunemikhiqizo evamile. Indlela yokukhetha isibani se-LED salesi sibonakaliso? Uma uthenga, kufanele ucabangele le iphethini. Emandleni ka-40 W, ukuhamba kwe-400 lm, 60 W - 600 lm, njalonjalo.

Umbala ogqamile

Le nkhomba ihlukanisa ama-LED avela ezikhanyeni ze-incandescent. Kungenziwa kukhethwe ngokubanzi, ngokungafani nezibani ze-incandescent, lapho umbala obomvu kakhulu. Ukwenza kube lula ukunquma amanani anjalo, isamba esikhethekile sakhiwe.

Yadalwa ngokushisa insimbi endaweni yokushisa ethile. Ngakho, umbala ophuzi kusho ukuthi ukushisa komkhumbi okhishwe yi-2700 K. Ukukhanya kwelanga kubonakala umbala omhlophe. Lapha izinga lokushisa lingu-6000 K. Konke okungaphezulu kwale nkhomba kunesici esihlaza okwesibhakabhaka.

Indlela yokukhetha isibani se-LED ngombala wemisebe? Kumele kukhethwe ngokusekelwe kokuthandayo. Okusho ukuthi, konke kuxhomeke kulokho okuzobonakala khona.

Ukulawula ukukhanya

Okunye ukukhanya kwezibani ze-DEL ukulungiswa kokukhanya. Ukuze wenze lokhu, udinga ukuthenga idivayisi ekhethekile. I-dimmer elawula i-LED ngamapulsi. Ngaphansi kwalokho, okungenani ukukhanya kwesibani, futhi ngokufanayo. Lokhu kushintsha akubonakali, ngoba imvamisa ingaphezu kuka-200 kHz. Ngakho-ke, amehlo abantu awaqapheli lokhu kukhanya. Nokho, akuzona zonke izibani ze-LED ze-volt ezingu-12 ezilungiselelwe. Lokhu akunakwenzeka ngenxa yomshayeli owakhelwe ngaphakathi, oguqula umkhiqizo kumvamisa othile.

Isiqondiso sokugeleza

Uma usebenzisa isibani se- diode, kufanele sicatshangelwe ukuthi ukukhanya kuqondiswa ohlangothini olulodwa. Le nkinga ayitholakali uma usebenzisa imikhiqizo yesibani esincane. Enye into, uma udinga ukumboza indawo enkulu kakhulu ekamelweni.

Ngale njongo, i-diffuser efakwe kumadivayisi.

Ibanga lokusebenza

Isibani se-LED sisebenza ngokushisa kwomoya--45 ° C kuya ku-45 ° C. Lokhu kuvumela ukuba zisetshenziswe ezimweni ezithile zokushisa.

Ezinye izici

Ngaphandle kokukhanya, i-LED ikhipha ukushisa okuncane, okungenakwenzeka. Iphuzu elibi kuphela ukuthi ukushisa akuhambisani nokukhanya, kodwa ngakwesinye isici, okungukuthi, ku-diode. Uma ikhishwa kakhulu, idivayisi ingalimala.

Isibani se-LED ngebhethri

Umkhiqizo onjalo usebenza ohlelweni oluvamile lwamandla kagesi nge-voltage engu-220 volts. Njengomthetho, lezi zibane zibekwe ngokugcwele kwazo iphaneli yokulawula ekhethekile. Isetshenziselwa ukuvula nokuvala. Ngenxa yebhethri eyakhelwe ngaphakathi, umkhiqizo ungasebenza ngaphandle kwegesi cishe amahora angu-24. Abasebenzisi abaningi bakholelwa ukuthi isibani se-LED esinamabhethri siyisetshenziswa esiwusizo.

Manje awudingi ukubuka inkinobho ebusuku. Kwanele nje ukucindezela inkinobho ephaneli. Izindleko zalo modeli zingama-ruble angu-600.

I-LED Light Bulbs i-Philips

Imodeli evamile kakhulu yalolu hlobo lwesibani i-Philips. Uma zivuliwe, ziphuma ekukhanyeni okufudumala okufudumele, okunikeza noma yiliphi igumbi elihle. Ngaphezu kwalokho, banomsebenzi wesikhathi eside, futhi futhi balondoloza ugesi kakhulu. Inzuzo yalo ebalulekile ukulawulwa kokukhanyisa. Ukukhanya okukhanyayo kusisiza ukuba ucabangele kangcono izakhi zokuhlobisa ekamelweni bese udala umoya ophephile ekhaya.

Phakathi kwezinhlobo eziningi kudingeke ukhethe umkhiqizo onjalo njengesibani samakhandlela. Iphelele ngokuphelele kunoma iyiphi ingaphakathi. Izindleko zemikhiqizo enjalo yi-ruble 400. Abasebenzisi abaningi baneliseke ngokuthi basebenzisa izibani ze-Philips ze-LED. Lena imishini yekhwalithi etholakala ngamanani aphansi.

Isiphetho

Imikhiqizo ye-LED yilawo madivaysi ekhwalithi akhonza ukukhanyisa igumbi nezinye izakhi zangaphakathi. Uma kuqhathaniswa nezibani ze-incandescent, zinezinzuzo eziningi. Kwezinzuzo ezibaluleke kunazo zonke, kufanelekile ukugqamisa ukulungiswa kokukhanya, uhla lokusebenza kanye nokukhanya okukhanyayo. Ngokuqondene nombuzo wokuthi ungakhetha kanjani isibani se-LED, okokuqala udinga ukutadisha zonke izici zobuchwepheshe. Kuphela emva kwalokho ungaya esitolo futhi uthenge inketho efanele.

Ngakho, sazi ukuthi singakhetha kanjani isibani esilungile se-LED.
