Dayactirka LED laambadihiinnuna gacmahoodii. Sida loo cusboonaysiiyo laambad LED a?

nalalka technology waxyaabaha saarka ayaa dhawaan helay nooc cusub oo qalabka macaamiisha ku salaysan xubno diode. In suuqa way loo yaqaan ay hogaaminayaan-nalalka. faafinta Active ah qalabka si ay u sameeyaan dhigooda qol oo dhaadheer iyo halogeen, in aan ku xuso dhaqanka laambadihii incandescent. Oo kanu waa sharaxaad ka, tan iyo laambadda LED waxaa hore u taagan sida qalabka isagoo khayraadka hawlgalka sare iyo tayada unsurpassed of iftiiminta. Tani waa run, laakiin hoggaamiyo-qalabka ma aha difaaca ka dhaawac, ka saar in mararka qaarkood ma fududa.

LED qalab nalalka

Si loo fahmo, waxa xubno ka waa in la macaamilooday in geedi socodka samaynta, waxaad u baahan tahay in aad barato laambadihii buux hoose. Sida iska cad, waxqabadka sare hawl suurto by sheyga farsamada. Sayidka, iyo laambadahoodii yaryaraa qalab LED waa:

• jirka ah (sida caadiga ah la design gaar ah iyo dhismaha);
• darawalka (Converter awood u qabata shaqo);
• il light (si toos ah uu Kokes);
• hiitarka;
• xubno indhaha.

Haddaba qiimihiisu aragti dhaw at kasta oo ka mid ah qaababka kuwan. Iyada oo jidhku waa cad - ma aha oo xiiso gaar ah marka la eego nidaamka laambad functional. Driver u dhaqmo sida unit awood diode ah, laakiin wax soo saarka lahayn danab iyo hadda joogto. Kokes ku soo saaro iftiinka by diinta koronto ka darawalka bixisey. Sidoo kale, qalabka laambad LED ka mid ah hiitarka iyo optics. First loo isticmaalo kulaalaya ilaa qaboojinta ee uu Kokes oo lenses la iftiinta ah (optics sare) waxaa loo baddalaa LED shucaaca waa la aqbali karo in la isticmaalo nuurka.

Baabi'inta luminaire ah

Aan howlgalkan ma aan samayn karo wax dayactir ah, inkastoo ay dhacdo hab nalalka laambadihii reerka u ekaan qalaad. Waxaa jira laba waji ee falanqaynta ee ay hoggaaminayaan-laambadihii. Xaaladda hore khuseysaa kaashawiito. Haddii model leeyahay feeraha waayo dhereg kulaylka, howlgalka u badan tahay inay ku guuleystaan - ku filan si aad u hesho furitaanka u dhexeeya feeraha ku haboon iyo isku dayaan in ay guryo gaar ah daab qalab. Tan iyo dayactirka LED laambadood oo aad gacmihiinna ku daruuri ma tilmaamayso bedelka ah ee qaybo ka haleysan, marxalad ee falanqaynta waa in si raaxa leh loola dhaqmo si ka kooban gudaha, taas oo ka mid ah guddiga circuit ku daabacan.

Habka labaad ee falanqaynta waa mid ku habboon in lagu daydo luminaire ah koob qaro weyn, taas oo mabda 'ma ku haboon yihiin khalkhalgelinta jirka. Waxaa jira hal trick: waa in aad qaadato qalajiyaha timaha iyo jirkooda kululeeyo - ka dibna dhegaan goobo galaas oo aan dadaal dheeraad ah la sii dayn doono ka saldhig cylindrical. qarsoodi ah ay tahay in saamaynta kaamerada of ballaarinta tirada walxaha, iyo Halabuurka koolo noqdo qof dabacsan - si timaha kulul LED laambadihii yihiin macno ahaan dumi.

Bedelaadda Supply Power ah

Waxaa ka mid ah dhibaatooyinka ay wadaagaan in lagu daydo qaar ka mid ah laambadihii LED la takooro karaan korontada, Gudaheedana waxaa ku capacitor ama resistor gubasho. Isku dayaysa in la qiyaaso waxqabadka instrumentation element this guud ahaan ma bixiyo natiijada la filayaa sababtoo ah khaladka la ogaado oo kaliya haddii la xidhiidha shabakada.

Si kastaba ha ahaatee, sida kaliya ee si loo xaliyo dhibaatada waa in la bedelo qaybta sida laambadihii dayactir LED u baahan karaan falanqaynta a full of guddiga for unu, taas oo ay adag tahay oo aan qalab gaar ah.

Waxaa muhiim ah in la ogaado in ee elektarooniga ah ku kaydi sida caadiga ah ma sameeyo, sidaa darteed waa in aad si toos ah u barta of sale tago oo weydii unit korontada qalabka korontada loogu talagalay ay hogaaminayaan-laambadood ee 5W. Waa maxay soo socota waa a manipulations yar oo sahlan oo la yeereyso ee jirka iyo ku rakibidda qayb cusub.

Haddii fiyuuska LED

Haddii korontada waxaa si caadi ah oo ka hawlgala, waxa macno u raadiyo dhibaatada ka mid ah uu Kokes ku. Ka hor inta aadan u samayn dayactir ah LED ee laambadihiinnuna gacmahooda iyadoo la bedelayo-shaqada aan alaabta, waa in aad hubsataa nooca diode u baahan yahay in la cusboonaysiiyo. Si arrintan loo sameeyo, u isticmaal batari ah 9 V iyo resistor ah (iska caabin ah 1 Ohm) in mid ka mid jeeg dioska- oo dhan.

Marka iin la ogaado, waxaa lagama maarmaan ah in la xiro warbaahinta ay. Sida caadiga ah, iyo laambadahoodii yaryaraa cooshado ilo xidhiidh la sameeyaa on mabda'a of silsilad, sidaas xiritaanka of mid ka mid ah waxay keeni doontaa in khasaaraha ka mid ah shaqo ee xubno kale - waxaa laga yaabaa in ay iftiin jiri doono xitaa ifaya. At dayactir marxaladdan ee LED laambadihiinnuna oo aad gacmihiinna ku suurto gal ahayn oo aan kabida. All dioska- desoldering ka weyn, guddiga ka dibna Wajigooda - ka dibna qaadeen raashin xubno cusub si ay u Waddooyinkiisa xiriir ah.

Features of dayactir ah "hadhuudh" ilayska

Marka la eego istareexsan ee model dayactirka taxane LL-hadhuudh, ie LED laambadihii sida "hadhuudh", ugu tara. Ilo LED waxaa si toos ah kooxda kaalinta on dusha dibadda u ogolaanaya in ninkii u hagaajinno laambadihii LED "hadhuudh", ma fara-ku-dhismeedka gudaha. Haddii loo baahdo, Kokes ku soo wici kartaa oo bedelay - technology la mid ah laambadihii dayactir habka la naqshado kale. Haleysan yahay ama diode Sidoo kale waa in la cusboonaysiiyo, ama gaaban buundada gaar ah. On the xasiloonida iyo isku halaynta qalabka LED kama beddelayso, laakiin in aragtida bilicsanaanta of maqnaanshaha mid ka mid ah ilaha iftiinka ayaa laga dareemi doono.

Unu in darawalladu

Tani element iniinahoodu ku dhex jiraan waa qaybta ugu kalsoonaan karo oo laambadda, sidaas darteed xaaladaha caadiga ah halkaas oo darawal la hayo, iyo inta kale ee buuxintii la Kokes ku updated. Ciladaha ku motherboards isla inta badan dhacaan sababta oo ah daawooyinka iyo isdhaaf ah ciriiriga in tilmaamayaasha hawlgalka magacaaban in muddo iyo sababa dadka isticmaala si ay u cusboonaysiiyaan darawalka LED laambad ama bedelka. Sababaha gaar ah oo darawal u yahay laambad joojinayso shaqada adag tahay in la garto. Haddii aan ka hadlo calaamadaha - LED biligleynaya in ay tahay, inay yihiin, in mabda, shaqaalaha, iyo xiriirada oo dhan si ay, laakiin dhexgalka la circuit Converter waa sax ahayn. Xaaladaha noocaas ah, bedeli karaa oo kaliya darawalka, iibsashada wax cusub raadiyaha - calaamadeynta sabuuradda kaa caawin doona inaad doorato qaabka ku habboon.

Hagaajinta laambadda lagu jiro dayactirka

Xaqiiqda ayaa ah dayactir wanaagsan oo ku filan, laakiin galidda ku qasbay qalabka qalabka siineysaa faa'idooyin qaar ka mid ah. Ka sokow xaqiiqda ah in bilaabayso baran kartaa sida loo cusboonaysiiyo laambadda LED oo aan gargaar ka mid ah xirfadlayaasha, waxa macno in ay isticmaalaan fursadaan si loo hagaajiyo tayada hawlgalka laambadda. Tusaale ahaan, inta lagu guda jiro dib u samaynta tijaabada waa in ay la hogaaminayaan-diode. Inta badan guddiga iyo qolof laftiisa la function saxanka kulaylka ma ku haboon yahay ee uu Kokes "hooyo" - sabab u ah a badan ama ka yar ku salaysan tayada qalabka ilaha iftiin ma aha ilaa ugu badnaan ay suurtogal tahay in sifooyinka warshadu hawada ku. Sidaa darteed, mararka qaarkood waxaa lagama maarmaan ah in si buuxda loo cusboonaysiiyo oo dhan dioska- ah.

Extended xaaladda dambe, marka salaysan aad u of no capacitor iyo rectifier ah. Sida caadiga ah, this dembi iin laambadihii Chinese, taas oo ay hirgeliyaan xiriir taxane ah oo lammaane oo "iska soo horjeeda" dioska- la capacitor waaya'aragnimo, taas oo horseedaysa bilig soo noqnoqda. Dabcan, dayactirka ee nalalka LED iyo baabi'iyo doonaa iin this, laakiin qorsheyaasha dib sida guriga ma bixiso cimri dherer of qalab, inkastoo tayada nalalka, dabcan, waxay kordhin doontaa.

gunaanad

Inkastoo faa'iidooyinka cad ee ay hoggaaminayaan-laambadihii, saarayaasha aan weli la shaqeeyay dad badan oo ka mid ah Gudigga farsamada qalabka dhamaadka dhalashada labaad. dhibaato ayaa ka mid ah qaab-dhismeedka iyo qalabka laambad gudaha ayaa keentay in xaqiiqda ah in liiska balaariyay qaybaha ku xiran failure. Waxaa xaaladda sii xumeeyay by xaqiiqada ah in dayactirka ah ee LED ee laambadihiinnuna gacmahoodii waa weyn u kala duwan oo ka tirsan howlgalka ay u soo celiyaan ilo iftiin dhaqanka iyo in ka badan caadiga ah. user u baahan aqoonta qaar ka mid ah waxyaabaha aasaasiga ah ee injineernimada radio, xirfad bir ah, kabida, laakiin waxaas oo dhan waxaa inta badan xoojiyay by baahida loo qabo in si ay u bartaan ma wadayaasha raqiis ah oo uu Kokes. Anyway,-qalabka ay hogaaminayaan in waxqabadka ugu fiican ee ka mid ah soo saarayaasha tilmaamay waxay leedahay faa'iidooyin badan, taas oo iyaga waa la cafiyayaa karaa xitaa dayactir adag.
