Cov tuam txhab tsim teeb dej nyab LED qhia koj yuav ua li cas thiaj tshem tau lub teeb thiab yuav siv nws li cas
Thaum siv dej nyab teeb sab nraum zoov, feem ntau yuav muaj hmoov av. Yog tias nws tsis raug ntxuav, nws yuav cuam tshuam qhov pom kev ntawm qhov pom kev. Siv LED teeb pom kev zoo los so plua plav, koj tuaj yeem so nws nrog daim ntaub huv. Nws zoo ib yam, tab sis tib neeg qhov muag tseem tuaj yeem pom cov hmoov av kom meej. Cov chaw tsim teeb dej nyab yuav qhia koj qee yam ntxiv.
Kev kho ntawm LED dej nyab teeb yuav tsum muaj cov ntsiab lus hauv qab no:
1. Txheeb xyuas cov cuab yeej, peb coj lub teeb dej nyab, thaum lub sijhawm saib xyuas txhua hnub, yog tias koj pom teeb meem nrog lub cuab yeej, koj tuaj yeem kho nws raws sijhawm.
2. Lub kaum sab xis ntawm lub teeb ci LED tawm los ntawm lub sijhawm ntev&"cua los ntawm lub qhov muag mus rau dej &";
3. Hauv kev tshuaj xyuas txhua hnub, yog tias muaj cov kab tawg hauv iav ntawm lub ntsej muag ntawm lub cev, lub teeb pom kev zoo yuav tsum tau muab tshem tawm tam sim ntawd kom tsis txhob raug mob.
1. Main LED teeb dimming tshuab
Peb txoj hauv kev dimmer hauv qab no yog txhawm rau faib cov kev tswj tso tawm ntawm LED tsav tam sim no. Kev tswj hluav taws xob kuj tseem tuaj yeem faib ua kev sib piv thiab PWM kev tswj hwm feem ntau yog ua los ntawm lub microcontroller.
Thawj qhov dimming feem ntau hu ua analog dimming mode lossis linear dimming.
Qhov kom zoo dua ntawm qhov dimming no yog nce linearly lossis txo tus tsav tam sim no nrog muaj zog tiv thaiv rau kev tswj Circuit Court ntawm LED nti. Qhov tsis zoo yog qhov kev hloov pauv ntawm kev tsav tsheb tas li cuam tshuam rau xim kub ntawm LED nti, thiab cuam tshuam rau xim kub ntawm LED nti.
Hauv qhov thib ob dimming, txij li qhov ci ntawm LED nti thiab LED tsav tam sim no muaj qhov sib piv ruaj khov, qhov ua kom pom kev ntawm lub teeb ci LED tau pom los ntawm kev kho qhov tsav tam sim no ntawm LED.
Qhov thib peb txoj kev dimming yog hom mem tes teeb modulator (PWM).
Txoj hauv kev ua rau nws muaj peev xwm txuag lub sijhawm thaum hloov pauv lub zog tso tawm, thaum hloov pauv lub xwmfab tsav tam sim no, qhov sib txawv ntawm cov mem tes dav thiab kev hloov pauv ntawm lub plawv dhia los ntawm kev tswj tas li. Feem ntau, qhov hloov pauv zaus ntawm 200hz txog 10khz, vim tib neeg lub qhov muag tuav lub zeem muag, tib neeg yuav tsis hnov qhov txav ntawm lub teeb ci. Qhov kom zoo dua ntawm txoj kev no yog tias nws tuaj yeem txhim kho cov cua sov ua kom sov ntawm LED. Qhov tsis zoo yog tias kev tsav tsheb ntau dhau tam sim no muaj qhov cuam tshuam rau lub neej ntawm LED nti.
2. Dimming system thiab kev txhim kho yav tom ntej
Kev tswj hwm zoo tshaj plaws yuav tsum muaj kev tswj phau ntawv, tswj ntse, tswj qhov muag, tswj lub sijhawm thiab ceeb toom kev ua haujlwm. Nws yuav qhib lub teeb thaum nws tsaus ntuj, thiab teeb pom kev ntawm 12 o' moos nyob nruab nrab ntawm hmo ntuj tseem yuav raug txiav ib nrab. Tom qab kaj ntug, lub hnub yuav tawm mus;
Hauv qhov xwm txheej tshwj xeeb, tib neeg tuaj yeem tswj hwm tus kheej;
Dab tsi yog cov yam ntxwv ntawm SMD dej nyab teeb?
1. Lub teeb pom kev zoo tau txais cov khoom ci ci ci ci ci ci ci ci ci ua ke ua ke, kev teeb pom kev zoo qib qib lub teeb pom kev zoo, lub teeb dawb huv, ua kom xim zoo;
2. Cov khoom siv aviation aluminium high-concentration tau nthuav tawm thiab tsim, thiab saum npoo yog anodized thiab tawv, thiab saum npoo muaj qhov ci siab thiab ci zoo. Qhov saum npoo ntawm lub teeb txawb tau khov kom ua rau lub teeb pom kev zoo dua qub thiab zoo ib yam, tsis muaj qhov ci;
3. Kev lag luam-qib cov tshuab cua sov ua kom sov, siv cov ntawv tooj liab ua kom sov thiab aluminium alloy radiator, dhau los ntawm huab cua ncig, kom cov cua sov ua kom zoo dua qub, thiab cov tshuab cua sov zoo tshaj tuaj yeem ua kom lub zog tsav tsheb thiab lub teeb ci kom kawg ntev dua;
4. Lub zog txuag hluav taws xob tau pom tseeb. Lub zog loj LED lub teeb ci tau teeb tsa nrog cov khoom siv hluav taws xob zoo, uas tuaj yeem txuag ntau dua 80% ntawm lub zog piv nrog cov teeb ci sodium.
Nws yog qhov tsim nyog rau sab hauv tsev thiab sab nraum zoov teeb pom kev zoo xws li chaw tsim kho, chaw ua haujlwm hauv tsev, chaw khaws khoom, chaw tos tsheb loj, chaw nres tsheb, khw muag khoom loj, chaw tso khoom, chaw ua si, thiab lwm yam.
