SMD-LED: imbali kunye eziphambili neempawu

LED iziphumo mntu wabona okokuqala kwiminyaka 90 eyadlulayo. Oku kwenzeka eRashiya ngowe-1923, xa Oleg Losev e Nizhny Novgorod yaqala nibonwe chweba of lesilicon khabhayithi kwilebhu yekhompyutha. amanqaku Scientific ngalo mbandela zapapashwa 30 kwinkulungwane yokugqibela, kwaye uyilo lokuqala ukuvela kuphela 70s. eLeningrad, Zelenograd kunye ukulungela ukusebenza. uphuhliso Active ndlela ezinxulumene ne-odolo amapolisa ezendlela ukuba nokuveliswa iirobhothi ngo-1000 ukuya kwi 850 isikhumbuzo kwikomkhulu, apho endaweni izibane ezingqengezelayo yasebenzisa LED ohlaza.

I-LED i chip semiconductor eqhotyoshelwe ukuya zeendawana le-alumuniyam okanye ubhedu nesilungiselelwe inkqubo enombala kunye ezinjengeetheminali. LED SMD (umphezulu iinkcukacha montage) kwezinye iintlobo ungachazwa ukuba iinxalenye ekulo ziyaxhonywa ngqo phezu komhlaba. izakhiwo Crystal ngokuba obu bugcisa bazibonise yi epitaxy organometallic. Ngethuba lale nkqubo, phakathi ngenye imini, ungenza ukukhulisa isakhiwo olifunayo (iitshiphusi) ubuninzi substrates 12.

Kamva, le ziikristale ifunyenwe baphathwa ngokusebenzisa zobugcisa eziphakamileyo, elibizelwe ndawonye iziphumo wenza uvuthuluka isicelo, izinto ezongezelelweyo yaye ebikunqwenela amalungiselelo ubushushu egxininisa. Eli nyathelo iindleko kakhulu, ngoko SMD LED zibiza kakhulu kunezi eziqhelekileyo. Kukholelwa ukuba ixabiso le mithambo nganye eveliswa yi-LED izihlandlo 100 ngaphezulu kwe efanayo unit wavelisa kunye isibane halogen.

Ezona mpawu ezintle ezi nkqubo ziquka abile, umbala ngobunyulu phezulu, kungekho infrared kunye ultraviolet radiation namandla ngokwaneleyo, iyahlala nokhuseleko. Namhlanje liruyuschey ilizwe onke, apho imveliso SMD-LED, i Japan.

Xa sisebenza kwezi zinto zikholisa ingqalelo ezi mpawu zilandelayo:

- ukukhanya, leyo ingaba mhlophe (eshushu okanye ebandayo), blue, oluhlaza, mthubi okanye obomvu. ukukhanya White SMD-LED zazifunyanwa ngeendlela ezininzi, kuquka RGB indlela, xa imibala eyahlukileyo zixubene yi lens okanye enye inkqubo optical;

- kwilizwe awazalelwa kuyo chip (njenge, Taiwan);

- ekubhobhozeni liqaqambileyo (lumens);

- efunekayo ombane;

- inani ziikristale (chips);

- amandla ayimfuneko yangoku;

- engile sokukhanyisa (degrees 45 ukuya 140);

- ubukho okanye ukungabikho zeendawana, nto leyo kwakudla iindleko ezongezelelweyo.

SMD-LED zisetyenziswa kakhulu ukukhanyisa kwiindawo ezininzi ezahlukeneyo. bayila zabo uthando umgangatho ophezulu yokukhanya kunye nokhuseleko kombane, abasebenzi Izixhobo zikaWonke - ukutyiwa amandla kunye nokumelana eliphezulu vandal. Le ngaphandle kuphela isicelo ubuchwepheshe namhlanje ubukho kwiindawo ezinkulu, ngoko ke azisetyenziselwa kwimveliso. strip LED kunokubonwa namhlanje kumakhaya, cafes-ofisi, kubandakanywa nabo kwimimandla kunye bume kufumile, usompempe uvumelekile, ngokuba kukho iintlobo ezithile ilight ningoyiki amanzi.

Ubomi inkonzo zezi zixhobo mkhulu kakhulu (ukuya kuma kwiiyure ezingama-50 000 njengezibonelo obuphezulu), ngoko ke ndithi, SMD-LED - sesona sixhobo kakhulu ukukhanyisa elizayo.
