Lub sijhawm pib:Muaj ob hom kev pib lub sijhawm rau cov khoom siv teeb pom kev ua kis las: pib sai sai thiab pib qeeb, uas yuav tsum tau xaiv kom tsim nyog raws li qhov tshwj xeeb ntawm qhov project.
Impulse tam sim no ntau yam:Thaum lub teeb pib, muaj qhov tam sim no loj tshaj qhov ntsuas tam sim no, uas yog hu ua impulse tam sim no.Qhov piv ntawm cov impulse tam sim no rau cov ntsuas kev khiav hauj lwm tam sim no hu ua impulse tam sim no ntau.Tus nqi me me, qhov cuam tshuam me me rau ntawm lub zog faib hluav taws xob, uas muaj kev nyab xeeb dua.Raws li ib txwm muaj, qhov pib tam sim ntawd ntawm LED kev ua si teeb pom kev zoo tam sim no ntau yam kuj loj, siab li ze li ntawm 40 zaug;thaum lub sij hawm ncua sij hawm pib ntawm kev ua kis las teeb pom kev zoo impulse ntau yam tam sim no kuj me me, tsawg dua 2 zaug.Cov hlau halide teeb muaj lub sijhawm pib qeeb, yog li nws qhov cuam tshuam tam sim no kuj tseem me me, feem ntau tsawg dua 2 zaug.
Luminous flux voltage hloov tus nqi:Qhov ntsuas no qhia txog qib ntawm kev cuam tshuam ntawm kev ua kis las teeb pom kev zoo los ntawm qhov sib txawv ntawm qhov hluav taws xob, thiab yog qhov sib piv ntawm qhov hloov pauv ntawm lub luminous flux rau qhov hloov pauv voltage.
Kev sim tau pom tias LED kev ua si teeb pom kev zoo muaj qhov txo qis ntawm kev hloov pauv ntawm luminous flux voltage, uas yog Δφ% / ΔU%.Thaum qhov voltage yog qhov zoo sib txawv, ces Δφ% / ΔU% = 0.092, thaum qhov hluav taws xob tsis zoo sib txawv, ces Δφ% / ΔU% = 0.075.
Txawm li cas los xij, qhov ntsuas no ntawm cov hlau halide teeb yog qhov tsis zoo thiab tsis txaus siab.Thaum qhov sib txawv voltage yog qhov zoo, Δφ% / ΔU% = 38/10 = 3.8;Thaum qhov voltage sib txawv tsis zoo, ces Δφ% / ΔU% = 28/10 = 2.8.
Qhov taw qhia ntawm cov hlau halide teeb yog qhov loj, thiab kev hloov hluav taws xob muaj kev cuam tshuam zoo rau nws cov luminous flux.Tus nqi ntawm LED teeb pom kev zoo yog qhov me me, tsawg dua 3% ntawm cov hlau halide teeb, uas yog, cov luminous flux tseem tsis tau hloov pauv hauv qhov sib txawv ntawm qhov sib txawv, thiab nws muaj cov yam ntxwv zoo voltage.
THD:Vim tias cov khoom siv teeb pom kev ua kis las feem ntau yog ib lub sijhawm thauj khoom, cov kev sib haum xeeb yog qhov thib peb.Yuav tsum tau ceeb toom, tsis yog tsuas yog yuav tsum tau them sai sai rau qhov teeb meem ntawm kev sib haum xeeb ntawm cov teeb thiab teeb, tab sis kuj muaj teeb meem sib haum xeeb ntawm kev tswj hwm, tshwj xeeb tshaj yog cov dimming module yuav ua rau kom muaj kev sib haum xeeb.
Peb-theem imbalance:Qhov teeb meem no tsis yog tshwj xeeb rau kev ua kis las teeb pom kev zoo.Tag nrho cov khoom siv hluav taws xob ib zaug tuaj yeem muaj peb-theem thauj khoom tsis txaus.Ua ntej tshaj plaws, nws yog ib qho tsim nyog los daws qhov teeb meem hauv kev tsim, sib npaug faib cov khoom thauj ib-theem mus rau peb-theem, thiab khaws peb-theem load tshuav nyiaj li cas ntau npaum li qhov ua tau raws li ntau hom kev tswj.Qhov thib ob, sim ua kom peb lub sijhawm ua haujlwm sib luag kom ntau li ntau tau thaum lub sijhawm ua haujlwm.
Kev tiv thaiv qib tiv thaiv hluav taws xob poob ntawm LED luminaire:Cov teeb pom kev ua si sab nraum zoov yuav tsum raug cais raws li Chav Kawm I, thiab cov teeb pom kev ua si sab hauv tsev tuaj yeem yog Chav Kawm I lossis II.Lub teeb pom kev hauv qab dej yuav tsum siv AC ntsuas qhov hluav taws xob tsis siab dua 12V lossis DC tsis siab dua 30V.Chav kawm III teeb.
Kev tiv thaiv luv luv:Qhov no yog qhov tsim nyog thiab qhov yuav tsum tau ua, thiab nws yog tus qauv tsim.
Kev tiv thaiv overload:Qhov no yog qhov yuav tsum tau xaiv.Nws raug pom zoo kom teeb tsa rau qhov chaw qis thiab nruab nrab;Nws raug nquahu kom tsis txhob teeb tsa rau qhov chaw siab, lossis teeb tsa kev tiv thaiv overload uas ua rau lub tswb.
Residual tam sim no kev tiv thaiv:Cov chaw qis qis tuaj yeem teeb tsa, tau kawg, lossis tsis;Cov chaw nruab nrab-siab yuav tsum tsis txhob teeb tsa, lossis teeb tsa cov kev tiv thaiv seem tam sim no uas ua rau lub tswb.
