Vim li cas LED txoj kev teeb pom kev tsaus nti thiab tsaus dua?Dab tsi ua rau lub teeb ci ntawm LED teeb?LED teeb lwj yog ib qho ua rau cov teeb meem no.Zoo, lub teeb lwj yog dab tsi, ua rau lub teeb lwj thiab yuav daws li cas.Don Tsis txhob txhawj!Qhov teeb pom kev zoo blog no yuav qhia cov lus teb ib los ntawm ib qho.
LED teeb fixtures muaj teeb meem poob, uas yog ib tug universal phenomenon.Different LED cov khoom, lub teeb lwj lub zog yog txawv.Lub teeb pom kev lag luam tus qauv yog xoom lub teeb lwj rau 1000 teev, 1 feem pua rau 3000 teev, 3 feem pua rau 10000 teev, 30 feem pua rau 50000 teev. Feem ntau, nws yog ib txwm coj teeb pom kev zoo teeb pom kev zoo yog tias ncav cuag cov qauv kev lag luam saum toj no.
LED teeb pom kev zoo yog dab tsi?
LED teeb pom kev zoo yog hais txog tias lub teeb siv zog yuav qis dua qhov qub lub teeb siv tom qab lub sijhawm teeb pom kev zoo ntawm LED, thiab qhov qis dua yog LED teeb lwj.Qhov ci ntsa iab ntawm tag nrho cov teeb pom kev zoo yuav qis dua qhov pib tom qab ib ntus. Kev siv.Yog li lub teeb lwj kuj muaj feem xyuam rau lub neej kev pab cuam ntawm LED teeb.Lub teeb pom kev zoo yog 50 feem pua -60 feem pua ua ntej coj teeb pom kev zoo fixtures ncav cuag nws qhov kawg ntawm lub neej.Lub teeb lwj yog ib qho ntawm cov ntsiab lus los qhia lub teeb quality.Qhov zoo ntawm cov teeb pom kev zoo uas tsis tshua muaj teeb pom kev zoo yog siab dua.Yog li ntawd, nws yog ib qho tsim nyog yuav tau xaiv cov khoom siv sab nraum zoov coj teeb pom kev zoo uas tsis muaj teeb pom kev zoo.
Dab tsi ua rau lub teeb lwj ntawm LED txoj kev teeb?
Qhov teeb meem kub dissipation ntawm LED txoj kev teeb
Qhov kub thiab txias yog qhov tseem ceeb ua rau lub teeb lwj ntawm LED txoj kev teeb.Lub zog luminous ntawm LED txoj kev teeb yog siab dua cov teeb hauv tsev, yog li coj txoj kev teeb pom kev zoo rau cov neeg tsim khoom siv hluav taws kub dissipation substrate fin thiab tshav kub dissipation module.Tom qab kev sib dhos, nws yog ib qho tsim nyog yuav tsum tau ntxiv cov xim sab nraum lub tshav kub dissipation module ntawm lub teeb kom tsis txhob muaj huab cua yaig.Tshwj xeeb, cov xim pleev xim ntawm cov kev tiv thaiv sab nraud tau kaw cov cua sov ntawm cov cua sov dissipation module rov qab, ua rau cov cua sov tsis zoo, thiaj li ua rau teeb meem ntawm LED teeb lwj.
Ntxiv nrog rau qhov teeb meem kub kub ntawm LED teeb, qhov kev tshaj tawm blog no kuj tau piav qhia ob yam hauv qab no ua rau lub teeb lwj.
Qhov zoo ntawm LED khoom nws tus kheej
1.LED nti zoo tsis zoo, brightness attenuation sai
2.Vim qhov tsis xws luag nyob rau hauv cov txheej txheem ntau lawm, lub tshav kub dissipation ntawm LED nti yuav tsis zoo exported los ntawm tus PIN, ua rau lub siab kub ntawm LED nti thiab aggravated lub attenuation ntawm coj teeb brightness.
Tus tsav tsheb
1.LED yog tsav los ntawm qhov tam sim no, thaum qee qhov LEDS tau tsav los ntawm qhov hluav taws xob, uas ua rau LED attenuation ntau dhau.
2.Kev tsav tsheb tam sim no ntau dua qhov ntsuas kev tsav tsheb.
Raws li cov ntsiab lus, muaj ntau yam laj thawj rau LED teeb lwj, tab sis qhov tseem ceeb tshaj plaws yog qhov teeb meem kub dissipation.Yog li cov kev daws teeb meem rau cov teeb meem kub dissipation ntawm cov teeb coj teeb yuav zoo txhim kho lub teeb pom kev tsis zoo, thiaj li ua kom lub neej ntev ntawm cov coj teeb pom kev zoo. txoj kev teeb.
Kev daws teeb meem teeb meem teeb meem ntawm LED txoj kev teeb
3 cov kev daws teeb meem tau teev tseg hauv qab no:
1.Nws tau tawm tswv yim tias coj txoj kev teeb pom kev lag luam pib los ntawm cov ntaub ntawv yooj yim, thiab daws qhov teeb meem ntawm lub zog siab LED hluav taws xob los ntawm sab hauv tawm.
2. Siv cov thermal conductive nplaum zoo, mos ceramic thermal conductive nplaum yog pom zoo.Piv txwv li, thermal conductive nplaum plays lub luag haujlwm tseem ceeb thaum lub sij hawm sib txuas ntawm cov luminescent tivthaiv rau aluminium substrate.Qee manufacturers xav tias thermal conductivity ntawm thermal nplaum. zaj duab xis los yog thermal nplaum ncoo yuav tsum zoo, lub thicker zaj duab xis, qhov zoo dua, tab sis tsis xav txog qhov teeb meem thermal kuj.Txawm li cas los xij, thermal conductivity zoo, nws tsis muaj txiaj ntsig los ntsib cov thermal resistance ntawm zaj duab xis thickness. ntau, cov thermal conductive zaj duab xis los yog mos thermal conductive gasket tsis tuaj yeem kaw nrog lub substrate, thiab muaj ntau qhov pores nyob rau hauv qhov chaw sib txuas.Thaum saib nyob rau hauv ib lub tshuab hluav taws xob, cov pores zoo li lub hnab ntim cua, lwm hom thermal kuj. Muaj ntau ntau yam thermal tsis kam uas cuam tshuam nrog kev siv hluav taws xob, qhov ua tau zoo ntawm cov cua sov dissipation thiab conduction yog txo qis.
3.Soft ceramic kub dissipating xim rau LED teeb yog pom zoo.Qhov no hom ntawm cov mos mos ceramic kub dissipation xim tuaj yeem raug txau ncaj qha rau sab nraud ntawm LED txoj kev teeb pom kev zoo, kev tsim kho yog yooj yim, tuaj yeem hloov mus rau ntau yam duab ntawm cov qauv kub dissipation, kuj tuaj yeem hloov kho rau hauv cov xim sib txawv, raws li kev xav tau ntawm kev tsim toj roob hauv pes.
Nws yog ib qho tshwm sim heev uas LED teeb tau tsaus thiab tsaus dua tom qab siv lub sijhawm.Ntxiv rau lub teeb lwj, muaj lwm 2 yam uas tuaj yeem ua rau LED teeb dim.Qhov ntawd yog: tsav tsheb puas, LED raug hlawv.
LED teeb hlaws yuav tsum ua haujlwm ntawm dc tsis tshua muaj hluav taws xob (qis dua 20V), tab sis peb lub zog hluav taws xob ib txwm yog AC high voltage (AC 220V). Cov hluav taws xob xav tau los tig lub ntsiab rau hauv lub teeb hlaws yuav tsum muaj cov cuab yeej hu ua "LED tam sim no tsav lub zog. muab "Nyob rau hauv txoj kev xav, ntev li ntev raws li qhov tsis sib xws ntawm tus neeg tsav tsheb sib tw nrog lub teeb hlaws lub rooj tsavxwm, nws tuaj yeem txuas ntxiv muab lub zog thiab nquag siv.Lub sab hauv ntawm tus tsav tsheb yog qhov nyuaj, txhua yam khoom siv (xws li capacitor, rectifier, thiab lwm yam. .) tshwm sim tsis ua hauj lwm, tej zaum yuav ua rau cov zis voltage hloov, thiab ces ua rau lub teeb dimming.Driver kev puas tsuaj yog feem ntau tsis ua hauj lwm nyob rau hauv LED teeb, feem ntau yuav daws tau tom qab hloov ntawm tus tsav tsheb.
LED nws tus kheej yog tsim los ntawm kev sib txuas ntawm lub teeb hlaws ib qho los ntawm ib qho, yog tias ib qho lossis ib feem tsis tau teeb, nws yuav tsum ua kom tag nrho lub teeb tsaus. Cov hlaws dai txuas nrog hauv series thiab tom qab ntawd nyob rau hauv parallel, yog li yog tias ib lub teeb hlaws kub hnyiab, Nws tuaj yeem ua rau tag nrho cov khoom ua tsis tiav.Ib qho LED yog kub hnyiab, tej zaum los ntawm kev sib tsoo.Yog kub hnyiab tawm, qhov teeb meem tsav tsheb yuav tsum raug xam tias yog - lwm qhov cim ntawm tus neeg tsav tsheb tsis ua haujlwm yog lub teeb ci hlaws.
