LED LED-isibani: incazelo ngebuhle nebubi

Ugesi okukhanyisa kwezakhiwo esetshenziswa isikhathi eside. Kwaphela isikhathi eside, ezindlini, amahhovisi, izitolo, izindlu nokunye. D. kuphela zisebenza ama-globe kagesi. Lezi amadivayisi ezincane Namanje ibhekwa ukusakaza ikakhulu sasivumela enamandla ukukhanya, ukuba konke okunye uyabukeka emehlweni umthunzi zemvelo. Nokho, incandescent ama babe nemiphumela ethile engathandeki several abalulekile. Ngaphezu kwakho konke, lokhu ukusebenza eqinile ngokuya amandla ukusetshenziswa a lifetime encane. Ngakho-ke, eminyakeni yamuva babe ukukhanyisa kuthandwa nezinye izinhlobo - ukonga futhi isikhathi eside. Lezi zingozi zihlanganisa ama, nokusungulwa akuyona kudala kwaholela LED-izibani.

Umlando omncane

LED kokuqala kwenziwa unjiniyela abadumile Nick Holonyak ngo-1962. Yakhelwe kumadivayisi abo ihlaba umkhosi ukukhanya ebonakalayo abomvu. Ngokushesha ngemva ukuvela kwalesi okusungulile ezithakazelisayo, inkampani US Monsanto uye wakubeka phezu ukugeleza ukukhiqizwa. Idivayisi wokuqala walolu hlobo ushiye yokwakha izimoto ngo-1968 Ikhishwa Monsanto ama zenzelwe ukusetshenziswa ngokuyinhloko emawashini digital nezibali. Ngakusasa amashumi eminyaka ambalwa, LED yasetshenziswa kuphela electronics ezimbonini kanye umthengi.

LED-isibani 220V, likhipha ukukhanya abe mhlophe qwa, futhi yakhelwe okukhanyisa kwezakhiwo ngetinhloso letehlukene, waqala ukuba sikhishelwe 1997 kuphela. UMdali idivayisi lokuqala onjalo kwakuyiNkosi American Fred Schubert. Esikhathini sethu, amadivayisi njenge ziye ezindaweni eziningi ezimbonini kanye yokuhlala.

Izakhi eziyinhloko kwesakhiwo

Modern diode ukukhanya-likhipha LED-izibani ziqoqwa kusetshenziswa izingxenye ezilandelayo:

• Cap. Njengoba ne izibani incandescent, ukuthi kuleli cala, element yakhelwe silingane idivayisi socket kwesibani.

• Abashayeli endaweni izindlu plastic ne imigodi umoya omncane. Kuhloswe ukuthi node yokuguqula ac ukuze dc. Ngaphezu kwalokho, umklamo walo kuhlanganisa capacitors ekhethekile edingekayo ukuze kuphole kwesibani. Esinye isici - a diode zener, esetshenziselwa nokulinganisa voltage lehla inethiwekhi.

• Sesipholisanjini. Lokhu umhlangano eyenziwe aluminium futhi eziningi kakhulu emaphethelweni. Kuyadingeka kwadambisa LED.

• Eyenziwe aluminium ebhodini. Ngakolunye uhlangothi ke elibheke kurediyetha, isicelo thermopaste ekhethekile. Ikhadi idluliswe mayelana 90% yokushisa sasikhipha LED.

• Diffuser. izibani LED ukukhiqiza ukukhanya ohlangothini kakhulu. Lo msuka design kwabo ukuhlakazwa yayo ukuze kungakhanyi ukukhanya iyunifomu egumbini.

• LED uqobo.

Njengoba ubona, uma iqhathaniswa nayo amadivayisi esikhipha ezivamile kubhekwe lapha akheke eziyinkimbinkimbi.

Kuyini LED

Yiqiniso, lo isici kule Isibani eziyisisekelo. Empeleni LED Uyi ekhethekile Semiconductor kudivayisi oguqula amandla kagesi ekukhanyeni. Izakhi eziyinhloko kwesakhiwo zedivayisi yilezi:

• Substrate, lamanje conductive.

• Wabeka crystal wakhe LED.

• Leli bhokisi, okuyinto ufaka zombili lezi zici. Kolunye uhlangothi oxhumana zitholakala, kanti omunye lens. Phakathi yokugcina kanye chip LED ligcwele abicah.

• Aluminium isizinda lapho benzelwe zonke izinto.

Umgomo we operation

LED usebenza ngenqubo olukhethekile recombination of electron phakathi terminals ezimbili nge ntshashintshe ka conductivity. Ezindaweni lapho chip yokugcina kulolu hlangothi Yandisa doping acceptor okuphothula equkethe esincane electron, futhi ngakolunye - ephakanyiswe. Recombination kwenzeka ngokushesha ngemva kokuba isibani ivuliwe e inethiwekhi. Umphumela amandla ngokweqile, okuyinto iguqulwe ibe ecucuza elikhanyayo.

Izici Key

Abanikazi izindlu, amahhovisi, izitolo nezindawo zokuhlala, ngokukhetha LED LED-isibani, okokuqala banake imingcele ezintathu eziyinhloko:

1. I degree of ukushisa yokucucuza. Izibani yalolu hlobo ingase ikhiphe ukukhanya anemibala ehlukene. Amadivayisi ezishisa kakhulu zikhipha izinhlayiyana ekusakazeni abandayo, asetshenziselwa ngokuyinhloko ezikhungweni zomphakathi. Ukuze amafulethi nezindlu bavame ukukhetha izibani nge ukukhanya "efudumele". Lezi zilwane ezidumile baneminyaka ngaleyo ndlela models 2700, 3000 kanye 3300 K.

2. Cap hlobo. Inguqulo esezingeni kubhekwa LED-isibani E27. Amamodeli nge cap efanelekayo wonke izibani yasendlini. On ukudayiswa futhi kukhona Mignon LED kungenziwa ifakwe ilebuli E14.

3. kudivayisi Amandla. Njengoba yaziwa, ethandwa kakhulu kukhona izibani incandescent 60-100 Watt. Lezi zinombolo zivumelana 7-13 W LED.

Iyiphi idivayisi ukuthenga for the efulethini?

Ngakho, impendulo yombuzo othi kanjani ukukhetha isibani LED ekhaya, engeyona inkimbinkimbi. Inketho kangcono iyunithi yokuhlala izoba kanye E27 cap futhi efudumele ukushisa yokucucuza ka 2700 K.

Ngokuqondene namandla, kulesi simo, kukhethwa ngokuya incike ngaziphi izinjongo ezithile kucatshangwa ukusebenzisa kudivayisi. Ngakho-ke, egumbini lokuphumula noma ehhovisi kangcono trinadtsativattnaya isibani LED E27 (Analogue idivayisi 100W esikhipha). Emakamelweni kungcono ukukhetha imodeli at 7-10 Watts. Izibani efanayo Site ekhishini kanye ephasijini encane.

amadivaysi izinzuzo

Ngakho lokho ncamashi Kuyinzuzo ezahlukene LED-isibani? Izibuyekezo amadivayisi yalolu hlobo ngokuyisisekelo okuhle. Ngokusho abathengi, zingabantu:

1. Okwezomnotho. Idivayisi kwalesi silwane sisebenzisa amandla ancishiswe izikhathi 20 kuka ngesibani esikhipha ngoba umfutho efanayo ukukhanya.

2. Yiba ukuphila isikhathi eside. LED asetshenziswa ngaphandle isidingo esikhundleni zisesikhathini eziyikhulu amahora.

3. Amelana ukushaqeka, vibration futhi okushisa aphansi. Nale isibani LED kungasetshenziswa kuhlanganise ukukhanya emgwaqweni.

4. Imvelo ephephile. Ngokungafani ezivamile amandla ukulondoloza, LED izibani akudingeki mercury. Lokhu kwandisa izinga sokuphepha ukukhanyisa futhi kusiza inqubo kabusha.

5. Imisebe yama-UV Unganikeli. Uma usebenzisa lolu hlobo isibani nokutubeka kwenzeka Upholstery, amaphethini zaveza nokunye okunjalo. D.

nemibi LED

Ngakho, izinzuzo isibani kwalesi silwane ziningi. Kodwa kukhona Yiqiniso, nezinkinga ezithile. izindleko High - wukuthi lokuqala zonke libhekisela nemibi idivayisi ezifana LED-isibani. Intengo abendlu LED ziyahlukahluka phakathi ruble 600-3000. On ukudayiswa, yebo, kukhona izinketho ashibhile, ekhiqizwa China ukuphi. Kodwa ukuthenga kubo ngokuqaphela. Iqiniso lokuthi eziphansi kulesi simo kungaba kuphela zingachazwa ngezinqubo ukonga izingxenye ingxenye.

Omunye ethile abalulekile izibani LED kuyinto ukuzwela kwabo voltage lehla. Ngezinye izikhathi izakhamuzi emadolobheni, ukufuya neziqinti komhlaba, uzibuze ukuthi ukukhetha isibani LED ekhaya ngaphandle komuzi. Ngeshwa, kuleli zwe ukusebenzisa amadivaysi ezinjalo abakwazi njalo, futhi konke ngenxa izinguquko kaningi voltage.

Enye Ububi izibani kwalesi silwane ubhekwa into abakwazi ukusonta ku luminaires avaliwe. Ngezinye okweqile njalo, amadivayisi njenge zilinyazwa kalula kakhulu. Ngesizathu esifanayo it is hhayi Kunconywa ukusebenzisa isibani LED ezindaweni ezikhethekile nge okushisa aphezulu kakhulu. Ngemva kwezinyanga eziningana ukusebenza ngaphansi kwalezizimo idivayisi uzoqala ukunikeza ukukhanya angamukelekile dim.

Iqiniso lokuthi lolu hlobo isibani Likhipha ekusakazeni ewumngcingo, kungabuye isibaluli yokuntula kwabo. Ukusebenzisa scatterer kwandisa izindleko idivayisi. Ngaphezu kwalokho, lapho amandla isicelo sasikhipha ecucuza elikhanyayo is kakhulu ziyancipha.

Abenzi ethandwa kakhulu

Brands amadivayisi yalolu hlobo emakethe yesimanje Russian has a lot of. Kungani nomkhiqizi okufanele akhethe, ngokukhetha idivayisi, okufana LED-isibani? Izibuyekezo amadivayisi yalolu hlobo ngokuvamile omuhle. Nokho, ukuthembeka enkulu, ngokuvumelana amakhasimende, imikhiqizo has brand European. IsiShayina ukukhanyisa esifanayo, njengoba sekushiwo, kungaba ozibongayo izinga akunjalo ngaso sonke isikhathi. Kungokufanayo kufanele wathi imikhiqizo abakhiqizi yasekhaya.

brand European ethandwa kakhulu, nahlulele by ukubuyekezwa, sebenzisa LED LED-isibani Artpole, ASD futhi Navigator. Eqolo Kulokhu kukhiqizwe ngokuqinile "ArtPole". ASD futhi Navigator ishibhile, kodwa ukunikeza elengeziwe dim okukhiphayo ukukhanya. Pretty okuningi isibani lezi abakhiqizi kuhluke design. Kodwa kulokhu isinqumo Yiqiniso, kuzoya siqu ukunambitheka okuthandwa umthengi.

Ngakho, izinzuzo main of izibani LED akunakubangelwa ngaphezu kwakho konke ukusebenza kahle futhi ukuphila isikhathi eside. plus yabo ongenambangi iyona ubumsulwa semvelo. Hlobo luni LED amalambu kangcono ekhaya noma ehhovisi? Ngokusho abathengi, imodeli Kungcono ukuthenga kusuka nomkhiqizi elihle. izindleko High buyafaneleka - ngezithukuthuku inzuzo - kuphela ithuluzi izinga. Eshibhile isibani Chinese, cishe, ngokushesha okukhulu behluleka.
