Advanced Facilities Efficient ProductionSab hluav taws xob thaiv hluav taws xob LED yog lub teeb pom kev, uas yog hom khoom siv kho kom zoo nkauj teeb pom kev zoo uas feem ntau siv hauv kev lag luam thiab tsev teeb pom kev zoo. Nws tsis tsuas yog muaj cov nyhuv ntawm teeb pom kev zoo, tab sis kuj siv rau kev kho kom zoo nkauj sab hauv vim nws qhov muag teeb pom kev zoo. Nws tuaj yeem hloov kho tib neeg lub siab lub ntsws thiab ua kom yooj yim rau tib neeg lub siab. Vim tias cov qauv thiab hom ntawm cov kev thaiv ib sab ntawm lub khw muag khoom yog ntau yam, cov neeg siv khoom yuav tsum nkag siab yuav ua li cas txuas cov ntawv pleev xim rau sab ua ntej yuav khoom. ?
Yuav ua li cas txuas cov yeeb yaj kiab sab nraud coj
Ua ntej, daim ntawv tag nrho
1, daim ntawv yooj yim tandem
Feem ntau, cov LEDs 1 ~ LEDn hauv cov qauv kev sib txuas cov kab txuas txuas rau qhov kawg, thiab qhov tam sim no ntws los ntawm LEDs yog sib npaug. Rau qhov loj-me thiab batch LED, txawm hais tias qhov hluav taws xob ntawm ib qho LED tej zaum yuav sib txawv me ntsis, vim tias cov LEDs yog cov khoom siv tam sim no, nws yog qhov ua tau los xyuas kom meej tias cov sib txuam luminous sib ntxiv tau zoo sib xws, uas yog kev sib txuas yooj yim series. Lub LED muaj cov yam ntxwv ntawm Circuit Court yooj yooj yim thiab kev txuas tau yooj yim. Txawm li cas los xij, vim muaj kev sib txuas ua ke, thaum ib tus ntawm LED muaj qhov qhib tsis ua haujlwm Circuit Court, tag nrho cov hlua LED yuav raug tua, uas cuam tshuam rau kev ntseeg tau ntawm kev siv.
2. Kev sib txuas ua haujlwm nrog rau txuas nrog Zener diodes
Txhua LED txuas nrog hauv kev sib txuas nrog cov kev hloov kho sib txuas ntawm Zener diodes. Hauv qhov txuas no, qhov hluav taws xob tawg ntawm txhua tus Zener diode siab dua qhov ua hauj lwm voltage ntawm LED. Thaum lub LED ua haujlwm zoo li qub, vim tias Zener diodes VD1 ~ VDn tsis muaj kev coj ua, qhov tam sim no feem ntau ntws los ntawm LED1 ~ LEDn. Thaum txoj hlua hluav taws xob LED raug puas tsuaj los ntawm LED, VD1 ~ VDn tau muab qhib, tshwj tsis yog ntxiv rau lub faulty LED, lwm LED tseem muaj qhov tam sim no mus dhau thiab tshaj tawm lub teeb ci. Hom kev sib txuas no zoo heev txhim kho hauv kev ntseeg tau piv nrog cov series yooj yim.
Thib ob, tag nrho thooj txhij daim ntawv
1, daim ntawv yooj yim thaum uas tig mus
Cov LEDs 1 ~ LEDn hauv cov qauv kab hluav taws xob tau yooj yim txuas nrog thaum uas tig mus rau thaum pib thiab thaum kawg, thiab txhua LED tau raug rau tib qho voltage thaum lub sijhawm ua haujlwm. Nws tuaj yeem pom los ntawm cov yam ntxwv ntawm LED uas nws yog hom khoom siv tam sim no, thiab kev hloov me me hauv qhov hluav taws xob siv rau LED yuav ua rau muaj kev hloov loj hauv qhov tam sim no. Tsis tas li ntawd xwb, vim muaj qhov txwv ntawm LED kev tsim thev naus laus zis, txawm hais tias cov hluav taws xob siv hluav taws xob ntau ntawm LED, qhov sib txawv hauv qhov ua tau zoo yog qhov muaj feem, yog li thaum LED1 ~ LEDn ua haujlwm, qhov tam sim no ntawm txhua LED tsis sib npaug. Nws tuaj yeem pom tau tias qhov tsis txaus ntawm kev faib tawm tam sim no ntawm txhua LED tuaj yeem ua rau lub neej ntawm LED nrog ntau dhau tam sim no yuav tsum tau txo qis lossis txawm hlawv tawm. Txoj kev sib txuas no yooj yim dua. Txawm li cas los xij, kev ntseeg tau tsis siab, tshwj xeeb tshaj yog rau cov ntawv thov uas cov naj npawb ntawm LED loj heev, uas yog qhov ntau dua uas yuav ua rau muaj kev ua tsis zoo.
2. Tau ywj siab sib xws daim foos
Rau cov teeb meem cia siab tau nyob hauv kev sib txuam yooj yim, daim ntawv ywj siab txuam thaum ua si yog txoj kev zoo. Txhua LED nyob rau hauv hom no nws muaj nws qhov kev hloov pauv tam sim no (tsav V + tso tawm yog L1 ~ Ln, feem), kom ntseeg tau tias tam sim no ntws los ntawm txhua LED nyob hauv nws qhov yuav tsum tau muaj, nrog cov tsav tsheb zoo, ib qho LED Thaum kev tiv thaiv tiav thiab qhov txhaum tsis cuam tshuam rau lwm LED, nws tuaj yeem phim tus yam ntxwv ntawm LED nrog qhov sib txawv loj. Cov teeb meem tseem ceeb yog cov qauv ntawm cov tsav tsheb sib txuas tag nrho yog qhov nyuaj, tus nqi ntawm cov cuab yeej siv siab, thiab cov khoom ntim hauv lub ntim loj dhau, uas tsis haum rau ntau tus ntawm cov xov tooj ntawm Circuit Court.
