Kev tsom xam ntawm LED teeb pom kev zoo hauv thaj av txias
Tom qab 10 xyoo ntawm txoj kev loj hlob sai, LED teeb pom kev zoo tau nkag mus rau theem kev nce qib sai, thiab daim ntawv thov kev lag luam tau maj mam nthuav tawm los ntawm thawj cheeb tsam yav qab teb mus rau thaj tsam nruab nrab thiab sab hnub poob. Txawm li cas los xij, hauv daim ntawv thov tiag tiag, peb pom tias cov khoom siv teeb pom kev zoo sab nraum zoov siv nyob rau sab qab teb tau sim zoo nyob rau sab qaum teb, tshwj xeeb tshaj yog nyob rau sab qaum teb. Tsab ntawv xov xwm no txheeb xyuas qee yam tseem ceeb uas cuam tshuam rau LED teeb pom kev zoo hauv qhov chaw txias, pom cov kev daws teeb meem sib xws, thiab thaum kawg coj tawm qhov zoo ntawm LED teeb pom kev zoo.
Ua ntej, qhov zoo ntawm LED teeb pom kev zoo hauv qhov chaw txias
Piv nrog rau cov thawj incandescent teeb, fluorescent teeb thiab high-intensity gas paug teeb, kev khiav hauj lwm kev ua tau zoo ntawm lub LED ntaus ntawv yog zoo dua nyob rau hauv tsis tshua muaj kub, thiab nws muaj peev xwm txawm hais tias qhov kho qhov muag kev ua tau zoo tshaj nyob rau hauv zoo tib yam kub. Qhov no yog ze ze rau cov yam ntxwv ntawm qhov kub thiab txias ntawm cov khoom siv LED. Raws li qhov sib txuas qhov kub thiab txias, qhov luminous flux ntawm lub teeb yuav nce ntxiv. Raws li txoj cai cua sov dissipation ntawm lub teeb, qhov sib txuas ntawm qhov kub thiab txias yog ze ze rau qhov kub thiab txias. Qhov qis dua qhov kub ntawm qhov chaw, qhov qis dua qhov sib txuas qhov kub thiab txias yog ua tiav. Tsis tas li ntawd, txo qhov kub ntawm qhov sib txuas kuj tseem tuaj yeem txo cov txheej txheem tawg ntawm lub teeb pom kev zoo ntawm LED teeb thiab ncua lub neej kev pab cuam ntawm lub teeb, uas kuj yog cov yam ntxwv ntawm cov khoom siv hluav taws xob feem ntau.
Qhov nyuaj thiab kev ntsuas ntawm LED teeb pom kev hauv qhov chaw txias
Txawm hais tias LED nws tus kheej muaj qhov zoo dua hauv cov xwm txheej txias, nws tsis tuaj yeem tsis quav ntsej tias ntxiv rau qhov chaw teeb pom kev zoo. LED teeb kuj tseem cuam tshuam rau kev tsav tsheb, cov khoom siv lub cev, thiab huab cua pos huab, muaj zog ultraviolet thiab lwm yam huab cua hauv qhov chaw txias. Cov xwm txheej tau coj cov teeb meem tshiab thiab teeb meem rau kev siv lub teeb pom kev tshiab no. Tsuas yog los ntawm kev qhia meej txog cov kev txwv no thiab nrhiav cov kev daws teeb meem, peb tuaj yeem muab kev ua si tag nrho rau qhov zoo ntawm LED teeb qhov chaw thiab ci hauv qhov chaw txias.
1. Tsawg kub pib teeb meem ntawm kev tsav tsheb fais fab mov
Txhua tus neeg uas ua qhov kev tsim hluav taws xob tsim hluav taws xob paub tias qhov kub qis pib ntawm lub zog hluav taws xob yog qhov teeb meem. Qhov laj thawj tseem ceeb yog tias feem ntau ntawm cov kev daws teeb meem uas twb muaj lawm tam sim no yog sib cais los ntawm kev siv ntau ntawm electrolytic capacitors. Txawm li cas los xij, nyob rau hauv qhov chaw qis qis qis dua -25 ° C, qhov kev ua haujlwm ntawm electrolytic ntawm electrolytic capacitor yog txo qis, thiab lub peev xwm capacitance yog heev attenuated, uas ua rau lub Circuit Court malfunction. Yuav kom daws tau qhov teeb meem no, tam sim no muaj ob txoj kev daws teeb meem: ib qho yog siv cov khoom siv hluav taws xob zoo nrog qhov dav dav ntawm kev khiav hauj lwm kub, uas tau kawg yuav nce nqi. Qhov thib ob yog kev tsim hluav taws xob siv hluav taws xob electrolytic capacitors, suav nrog ceramic laminated capacitors, thiab txawm tias lwm yam kev tsav tsheb xws li linear drive.
Tsis tas li ntawd, nyob rau hauv ib puag ncig uas tsis muaj qhov kub thiab txias, qhov kev tiv thaiv hluav taws xob ntawm cov khoom siv hluav taws xob zoo tib yam kuj yuav txo qis, uas yuav cuam tshuam rau tag nrho kev ntseeg siab ntawm Circuit Court, uas yuav tsum tau saib xyuas tshwj xeeb.
2. Kev ntseeg siab ntawm cov ntaub ntawv yas nyob rau hauv qhov kub thiab txias cuam tshuam
Raws li kev sim ua los ntawm cov kws tshawb fawb ntawm qee lub koom haum tshawb fawb hauv tsev thiab txawv teb chaws, ntau cov khoom siv yas thiab cov roj hmab zoo tib yam muaj cov khoom tsis zoo thiab muaj zog brittleness ntawm qhov kub qis dua -15 ° C. Rau LED sab nraum zoov cov khoom, cov ntaub ntawv pob tshab, optical lo ntsiab muag, seals thiab ib co. Cov yam ntxwv ntawm cov khoom siv yuav siv tau cov ntaub ntawv yas, yog li cov khoom siv hluav taws xob qis ntawm cov khoom siv no yuav tsum tau ua tib zoo xav, tshwj xeeb tshaj yog cov khoom siv thauj khoom, kom tsis txhob muaj cov teeb nyob rau hauv qhov kub thiab txias ib puag ncig, nws yuav tawg tom qab raug ntaus los ntawm cov cua muaj zog thiab kev sib tsoo.
Tsis tas li ntawd, LED luminaires feem ntau siv ua ke ntawm cov khoom yas thiab hlau. Vim hais tias qhov nthuav dav coefficients ntawm cov ntaub ntawv yas thiab cov ntaub ntawv hlau sib txawv heev nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, piv txwv li, qhov nthuav dav coefficients ntawm cov hlau txhuas thiab cov ntaub ntawv yas feem ntau siv hauv cov teeb yog li 5 npaug sib txawv, uas yuav ua rau cov ntaub ntawv yas tawg lossis qhov sib txawv. nruab nrab ntawm ob. Yog tias nws tau nce ntxiv, cov qauv sealing tsis muaj dej thaum kawg yuav tsis raug cai, uas yuav ua rau muaj teeb meem ntawm cov khoom.
Hauv thaj av alpine, txij lub Kaum Hli mus txog Lub Plaub Hlis ntawm xyoo tom ntej, nws yuav yog lub caij ntuj sov thiab dej khov. Qhov kub ntawm lub teeb ci LED tuaj yeem qis dua -20 ℃ nyob ze yav tsaus ntuj ua ntej lub teeb tig rau yav tsaus ntuj, thiab tom qab ntawd tom qab hluav taws xob qhib thaum hmo ntuj, qhov kub ntawm lub teeb lub cev yuav nce mus txog 30 ℃ ~ 40 ℃ vim cua sov ntawm lub teeb. Ua rau muaj kev kub ntxhov siab thiab qis qis. Nyob rau hauv ib puag ncig no, yog tias cov qauv tsim ntawm lub luminaire thiab qhov teeb meem ntawm kev sib piv cov ntaub ntawv sib txawv tsis ua haujlwm zoo, nws yog ib qho yooj yim uas yuav ua rau cov teeb meem ntawm cov khoom tawg thiab cov dej tsis zoo uas tau hais los saum no.
