Lub LED matrix yog ob qho tib si LEDs thiab LED sib dhos ua los ntawm ib pawg ntawm cov muaju. Cov matrices no tau siv dav hauv cov tshuab rau kev teeb pom kev dav dav ntawm cov khoom thiab thaj chaw, txoj kev thiab facades ntawm lub tsev, lawv kuj tau siv rau cov teeb pom kev zoo sab hauv, piv txwv li, tsom teeb. LED matrix tuaj yeem tsim, nyob ntawm lub hom phiaj, ob qho tib si lub teeb pom kev taw qhia thiab ib qho diffuse.
Qhov xav tau los kawm txog cov txheej txheem ntawm kev sib txuas lub zog hluav taws xob LED cov qauv, nrog rau cov qauv tsim thiab cov teeb meem thev naus laus zis cuam tshuam nrog cov txheej txheem no, tam sim no yog vim muaj qhov nrov ntawm cov khoom lag luam no, thiab, ntawm chav kawm, lub zog. ntawm qhov kev taw qhia ntawm kev lag luam teeb pom kev zoo. Yog vim li cas rau xws li ib tug loj kev cuam tshuam yog ib tug xov tooj ntawm zoo uas tau ua tiav raws li ib tug tshwm sim ntawm kev hloov luminescent, nqus tsev vacuum, gas-tso qhov chaw ntawm insolation nrog niaj hnub semiconductor teeb pom kev zoo. Nws tsis yog ib qho zais cia rau leej twg tias kev siv cov diodes hnyav tau txo qis lub zog noj, nrog rau kev nce qib ntawm kev ntseeg siab, ua haujlwm ntev thiab ib puag ncig tus phooj ywg ntawm lub teeb ci.
Vim qhov zoo li saum toj no, kev txhim kho thiab tsim cov thev naus laus zis tshiab tshaj plaws hauv thaj chaw ntawm cov khoom siv LED hnub no tau ua tiav ntawm qhov nrawm heev. Nyob rau tib lub sijhawm, qhov yuav tsum tau ua rau qhov zoo ntawm kev tawg ntawm lub teeb pom kev zoo, lub zog luminous ntawm semiconductor LEDs tau loj hlob tas li, uas txhais tau hais tias cov kev xav tau ntawm matrices tseem nce ntxiv.
Lub LED matrix yog ib pawg ntawm cov muaju txuas nrog raws li cov ntsiab lus sib xyaw - sib npaug-series. Tus nqi ntawm cov khoom siv hluav taws xob thiab tam sim no hauv LED arrays yog me ntsis siab dua qhov voltage thiab tam sim no ntawm LEDs yooj yim. Qhov no yog vim lub fact tias lub matrix muaj tag nrho cov pab pawg neeg ntawm semiconductor ntsiab. Rau kev ua haujlwm tau zoo thiab ruaj khov, LED matrix yuav tsum tau nruab nrog lub zog thiab ruaj khov qhov chaw tam sim no (los yog qhov chaw tam sim no thiab tsav tsheb), nrog rau lub dab dej kub. Feem ntau, aluminium lossis tooj liab radiator yog siv los ua lub dab dej kub.
Raws li kev xyaum qhia, lub zog LED matrices tau txais kev nyiam ntau dua hnub no. Tom qab tag nrho, cov khoom no ua rau nws muaj peev xwm txo tau tus nqi ntawm kev tsim lub teeb muaj zog vim yog kev koom ua ke ntawm ntau cov muaju rau hauv ib qho. Xws li kev sib xyaw ua ke tso cai rau cov tuam txhab tsim khoom tsis yog tsuas yog txo cov nqi tsim khoomcov khoom siv teeb pom kev zoo, tab sis kuj tseem txhim kho lawv qhov zoo. Qhov no yog vim hais tias LED matrix Circuit Court tau txo qis heev, thiab qhov yooj yim ntawm Circuit Court, qhov kev ntseeg tau ntau dua.
Ib qho tseem ceeb ntawm txhua qhov LED matrix yog luminous efficiency. Nws nyob ntawm qhov zoo ntawm lub teeb ci siv lead ua. Txawm li cas los xij, nws yuav tsum to taub tias txawm tias siv cov khoom siv lead ua siab, lub teeb pom kev zoo ntawm cov matrix yuav qis dua li qhov tso tawm tag nrho ntawm cov muaju uas muaj nyob hauv cov qauv tsim. Qhov no yog vim cov nyhuv ntawm superposition (kev sib nqus nqus) ntawm lub teeb hluav taws xob, diodes nyob ze ze.
