LED LED-isibane: inkcazelo ubuhle nobubi

Umbane yokukhanyisa kwizakhiwo ezisetyenziswa ixesha elide. Kangangexesha elide, barentayo, ii-ofisi, iivenkile, izindlu njalo njalo. D. isicelo kuphela ibhalbhu ukukhanya. Ezi zixhobo amancinci kuyibona umlambo ikakhulu enamandla ngokufanelekileyo ukukhanya, ukuba yonke enye into ezikholekileyo emehlweni umthunzi yendalo. Noko ke, ibhalbhu ezingqengezelayo kuneengxaki ezininzi ezibalulekileyo. Ngaphezu kwako konke, eli impumelelo eqaqambileyo ngokwemiqathango ukusetyenziswa kwamandla kunye ubomi encinane. Ngoko ke, kwiminyaka yakutshanje zibe izibane kuthandwa nezinye iintlobo - enoqoqosho ixesha elide. Le yokugqibela ziquka, yaye wayila ayikho kwakude kudala wakhokela LED-izibane.

A incinane

LED lwaba lolokuqala, injineli odumileyo Nick Holonyak ngo-1962. Lo Endliwa izixhobo zabo kukhutshwe ukukhanya okubonakalayo ebomvu. Kungekudala emva kokuvela yale enomdla, inkampani US Monsanto ubeke phezu nokungena kwimveliso. Isixhobo sokuqala sale hlobo washiya umgca ibandla ngo-1968 Iveliswe Iibhalbhu Monsanto enzelwe ukusetyenziswa kakhulu iiwotshi lwedijithali kunye nezixhobo zokubala. Eminyaka embalwa elandelayo, ii-LED ziye zasetyenziswa kuphela bombane mveliso kunye nomthengi.

LED-isibane 220V, idangatya ukukhanya okuqaqambileyo emhlophe, yaye yenzelwe yokucacisa indawo ngeenjongo ezahlukeneyo, waqalisa ukuba kukhutshwa ngo-1997 kuphela. UMdali isixhobo yokuqala yaba American uFred Schubert. Ekuhambeni kwexesha lethu, izixhobo ezo ziye zasetyenziswa kwiindawo ezininzi mveliso kunye neendawo zokuhlala.

Iimpawu zesakhiwo

Modern ukukhanya-esikhupha diode LED-izibane ziqokelelwa ngokusebenzisa amacandelo alandelayo:

• Cap. Njengoko kunye nezibane ezingqengezelayo, ukuba kulo mzekelo, i element yenzelwe ukulingana idivayisi okusikrotyana isibane.

• Abaqhubi kwi izindlu zeplastiki ezinemingxuma umoya. Kujongwe ukuba node lokuguqula ac ku dc. Ukongeza, uyilo yayo ibandakanya capacitors ezizodwa ukuze Ukupholisa isibane. Enye element - a diode zener, esetyenziselwa nokulinganisa loo ombane lihla kwi network.

• Radiator. Le ibandla yenziwa aluminiyam kwaye inani elikhulu kakhulu ezinemiphetho. Kuyimfuneko kwakhona Ukupholisa LED.

• Made ebhodi aluminiyam. Kwicala kwawo ejongene kwiradiyetha, isicelo thermopaste okhethekileyo. Ikhadi idluliselwa malunga-90% yobushushu ekhutshwa LED.

• Diffuser. izibane LED ukuvelisa ukukhanya zemiyalelo kakhulu. Le ilementi kuyilo zabo kwiintsali yayo ukuze ukhanyiso efanayo egumbini.

• LED ngokwayo.

Njengoko ubona, xa kuthelekiswa izixhobo ezingqengezelayo yesiqhelo ingqalelo apha isakhiwo ezimbaxa ngakumbi.

Yintoni i LED

Kakade ke, nayo le element Isibane esisiseko. Eneneni ii-LED esikhethekileyo isixhobo semiconductor leyo esiguqula amandla ombane abe ukukhanya. Iimpawu noshowo isixhobo zezi:

• Le zeendawana, i yangoku conductive.

• Wabeka crystal yakhe LED.

• Izindlu, leyo Uvingca zombini iziqalelo. Kwelinye icala abafowunelwa elise, yaye omnye lens. Phakathi yokugqibela kunye chip LED uzele abicah.

• base-aluminiyam apho ayinakutshintshwa zonke izinto.

isimiso ukusebenza

LED isebenza ngokusebenzisa inkqubo ekhethekileyo recombination of elektroni phakathi iiclamps amabini kumanqanaba angafaniyo conductivity. Kwiindawo apho chip yokugqibela kwelinye icala akunika kweziyobisi ukungcola acceptor equlathe imali encinane elektroni, yaye kwelinye icala - avuswe. Recombination kwenzeka ngokukhawuleza emva kokuba isibane ivuliwe kwi network. Isiphumo ungamandla agqithisileyo, nto leyo iguqulelwa wampompoza ezikhanyayo.

Iimpawu eziphambili

Abanikazi izindlu, ii-ofisi, iivenkile kunye zokuhlala, ukukhetha LED LED-isibane, okokuqala zonke sinikele ingqalelo eziphambili iparameters ezintathu:

1. Ubungakanani ngobhobhozo ubushushu. Izibane yale hlobo ungeniselo ukukhanya imibala eyahlukileyo. Devices ukuba kukhutshwe qa, zisetyenziswa ikakhulu kumaziko karhulumente. Kuba zokuhlala kunye nezindlu bayathanda ukuba ukhethe izibane ekukhanyeni "efudumeleyo". Iintlobo ithandwayo ngoko neemodeli 2700, 3000 no 3300 K.

2. Cap uhlobo. Inguqulelo standard igqalwa LED-isibane E27. Onobuhle ikepusi afanelekileyo zonke izibane indlu. On sale kwakhona mignon kukho LED ungenza zizakuboniswa E14.

3. isixhobo Power. Njengoko yaziwa, ethandwa kakhulu ke izibane ezingqengezelayo 60-100 Watt. La manani kunxibelelana 7-13 W LED.

Yeyiphi isixhobo ukuthenga kuba indlu?

Ngoko ke, impendulo yombuzo ukukhetha indlela i bulb LED ekhaya, ezingantsonkothanga. Eyona ndlela ilungileyo yokuhlala iya kuba E27 ikepusi nobushushu efudumeleyo flow 2700 K.

Njengoko igunya, kulo mzekelo, ukukhetha ngokuya kuxhomekeke oko ngeenjongo ezithile izakuthatwa njengokuba ukusebenzisa ifowuni. Ngoko ke, ngokuba kwigumbi lokuhlala okanye ofisi na izityalo trinadtsativattnaya bulb LED E27 (analogu isixhobo 100W zigqengezelayo). Lokulala kungcono ukukhetha imodeli kwi 7-10 watts. Izibane efanayo ezifanele ekhitshini kunye epasejini encinane.

izixhobo eziluncedo

Ngoko ke yintoni kanye Kuyinzuzo ezahlukeneyo LED-isibane? Izimvo iingcinga olu hlobo ezi buhle. Ngokutsho kubathengi, zezi:

1. Ukonga. Icebo ezi zilwanyana odla amandla amaxesha 20 ngaphantsi kwe i isibane yale igqengezelayo kuba ngamandla olufanayo ukukhanya.

2. Yiba ubomi inkonzo ende. LED zisetyenziswa ngaphandle imfuneko yokukhupha zezi phezulu enye ikhulu lamawaka iiyure.

3. Ukumelana njengomothuko, ukungcangcazela kunye namaqondo obushushu aphantsi. Ngale bulb LED zingasetyenziswa kuquka zisasetyenziselwa ukukhanyisa esitratweni.

4. Indalo ekhuselekileyo. Ngokungafaniyo kulimo amandla-ugcino, LED izibane abanalo mercury. Oku kwandisa izinga lokhuseleko kwezibane kwaye iququzelela inkqubo okurisayikilisha.

5. Musa ukunika radiation UV. Xa usebenzisa olu hlobo isibane ebekw kwenzeka entofontofo, iiphatheni beqabe kunye like. D.

lobubi LED

Ngenxa yoko, amancedo isibane ezi zilwanyana zininzi. Kodwa kukho, Kakade ke, neengxaki ezithile. ixabiso eliphezulu - kukuba kuqala kubhekiselele nengeloncedo isixhobo afana LED-isibane. Ixabiso LED yasekhaya ingahluka phakathi 600-3000 engange. On ukuthengisa, Kakade, kukho iindlela atshiphu, zenziwe e China. Kodwa uwuthenge ngononophelo. Inyaniso yokuba ixabiso eliphantsi kulo mzekelo ziyacaca kuphela imali kwiindawo candelo.

Enye ethile ebonakalayo izibane LED na uvakalelo lwabo ombane tsakisi. Maxa wambi abahlali ezixeko, ekubeni iziza ezincinane, bayazibuza ukuba ukhethe njani ibhalbhu LED ekhaya ngaphandle komzi. Ngelishwa, kweli lizwe ukuze basebenzise izixhobo ezifana abakwazi njalo, kwaye ngenxa utshintsho rhoqo kwi ombane.

Enye engxakini izibane ezi zilwanyana kucingwa ukuba babe yinto ukuba akufunekanga bajije ngayo luminaires ezivaliweyo. Xa nobushushu rhoqo, izixhobo ezinjalo ngokulula kakhulu yonakele. Ngenxa yesizathu esifanayo oko Kucetyiswa ukuba basebenzise isibane iLED kwiindawo ezikhethekileyo kunye amaqondo obushushu aphezulu kakhulu. Emva kweenyanga eziliqela ukusebenza phantsi kwezi meko isixhobo iya kuqalisa kunika ukukhanya engamkelekanga emnyama.

Isibakala sokuba olu hlobo isibane ikhala umlambo emxinwa, nazo zibangelwa lobubi babo. Ukusetyenziswa afumanane nomhlwayeli kwandisa iindleko kwefowuni. Ngaphezu koko, xa amandla isicelo ezintweni ekubhobhozeni ezikhanyayo yehliswe kakhulu.

Kubakhi kakhulu ethandwa

Brand of iingcinga olu hlobo kwimarike Russian mihla has a lot of. Kutheni umenzi kufuneka ukhethe, ukukhetha isixhobo, ezifana LED-isibane? Izimvo iingcinga olu hlobo HIV jikelele. Noko ke, ukuthembeka mkhulu, ngokutsho kubathengi, iimveliso uye yemiyinge zaseYurophu. Izibane chinese efanayo, njengokuba sele kukhankanyiwe, liyi umgangatho akusoloko kunjalo. Kunjalo kufuneka wathi iimveliso labavelisi zasekhaya.

brand yaseYurophu ethandwa, ebalawula yi-ncomo, sebenzisa LED LED-isibane Artpole, ASD kunye Umlawuli. Ezibiza kakhulu kule meko imveliso ngokuqinileyo "ArtPole". ASD kunye Navigator kubiza, kodwa anike kancinane ngakumbi dim Impahla ukukhanya. Intle kakhulu isibane ezi abenzi bahluka kuyilo. Kodwa ke kule meko ukhetho Kakade ke, iya kuxhomekeka kukhetho ukhetho lobuqu lomthengi.

Ngoko ke, lo iingenelo eziphambili izibane LED oku kubangelwe ngaphezu konke ukusebenza kunye nobomi inkonzo ende. plus lwabo olungenangxaki ke ntumbuluko eziphilayo. Luhlobo olunjani ibhalbhu LED ezifanele ukuba ikhaya okanye i-ofisi? Ngokutsho kubathengi, umzekelo kubhetele ukuba bathenge a kumenzi ezaziwayo. iindleko High uyagwetyelwa - ngeendleko inzuzo - kuphela isixhobo esemgangathweni. Cheap isibane Chinese, mhlawumbi, ngokukhawuleza kakhulu asilele.
