Yuav ua li cas kho LED teeb tsis tig rau
1. Qhov laj thawj vim li cas lub teeb ci LED tsis tig yog vim muaj ob qhov xwm txheej: Ua ntej, qhov hluav taws xob hluav taws xob ntau dhau ntawm LED yuav ua rau PN hlws ris tsis ua haujlwm, ua rau lub teeb LED tig tawm. Qhov thib ob, LED qhov sib txuas sab hauv yog txiav tawm, ua rau tsis muaj qhov tam sim no ntws los ntawm LED thiab ua rau lub teeb tuag.
2. Txhawm rau kho lub teeb ci LED, koj tuaj yeem siv lub tiaj tus ntsia hlau ntsia hlau los ua tib zoo rub tawm cov hlau ntsia hlau txuas ntawm LED lub teeb lub taub hau thiab lub ntsiab yas txuas ntawm lub teeb qhov muag, thiab khaws nws tag nrho tom qab kho. Tom qab qhib, xyuas cov khoom siv hluav taws xob ntawm qhov hloov dua siab tshiab. Yog tias tsis muaj teeb meem, xyuas qhov tso zis hluav taws xob los ntawm kev tig lub hwj chim. Nyob rau hauv cov ntaub ntawv ntawm 2W LED teeb, siv ib tug multimeter los ntsuas qhov tso zis DC voltage ntawm 105.5V, qhia tias qhov txhaum yog nyob rau hauv lub LED teeb-emitting ib feem.
3. Yog hais tias lub teeb LED teeb lub teeb-emitting ib feem yog disconnected los ntawm lub hwj chim qhov chaw, ces cov yas qhov muag teev ua los ntawm cov yas thiab cov yas lub cev uas txuas rau nws cov kev twb kev txuas yog sib cais. Txij li thaum ib feem yog glued rau, nws yuav tsis tuaj sib nrug kiag li thiab nws yuav ua rau lub teeb yas puas, tab sis nws tsis muaj teeb meem yog tias koj tsis siv nws. Tom qab kho, nws tsis cuam tshuam lub ci, nws tsis zoo.
4. Tom qab kho, ntxig daim ntawv plhaub ntsuab feem ntau siv los ntawm cov neeg siv hluav taws xob rau hauv cov hlau ntsia hlau lub qhov ncauj ntawm lub teeb npog. Daim ntawv lub plhaub ntsuab yog muab tso rau hauv lub cev yas kom cais cov LED teeb-emitting ntsiab lus los ntawm cov khoom siv hluav taws xob. Yog li, ua li cas koj thiaj paub tias cov teeb-emitting Cheebtsam puas tawg? Koj tuaj yeem siv qhov kev txiav txim siab tiv thaiv ntawm lub tshuab multimeter kom pom qhov tsis zoo. Kev kuaj liab thiab dub siv lub tshuab ntsuas ntau tau ua rau kev sim ntawm ob qho kawg ntawm nws lub teeb pom kev zoo LED. Koj tuaj yeem sim qhov kev xeem los ntawm kev tawm tsam, hla thiab sib pauv cov kev xeem liab thiab dub coj mus txog thaum pom pom qhov ci ntsa iab. Tom qab tag nrho cov ntsiab lus tau raug ntsuas, daim ntawv yog thawj kos rau txhua pab pawg ntawm luminescent Cheebtsam thiab peb luminescent ntsiab lus nyob rau hauv txhua pab pawg neeg, thiab cov ntsiab lus uas tsis yog-luminescent raug muab sau tseg rau kev sib piv thiab tshem tawm.
Yuav siv LED teeb li cas kom raug
1. Thaum ntxuav lub teeb LED vaj tse nrog cov tshuaj, yuav tsum tau saib xyuas, vim qee cov tshuaj yuav ua rau cov colloidal nto thiab ua kom tsis muaj xim, xws li trichloroethylene, acetone, thiab lwm yam. Nws tuaj yeem ntxuav thiab dipped hauv ethanol hauv tsawg dua 3 feeb ntawm chav kub.
2. Nyob rau hauv tus txheej txheem ntawm kev siv, txawm nws yog ib tug chip los yog multi-chip, nws yog pom zoo kom DC tsav tam sim no ntawm txhua LED yog nyob rau hauv qhov ntau ntawm 10-20mA.
3. Momentary pulses yuav rhuav tshem cov kev sib txuas ruaj khov hauv lub teeb ci LED, yog li lub voj voog yuav tsum tau ua tib zoo tsim kom lub teeb ci LED tsis raug overvoltage lossis overcurrent thaum txoj kab qhib thiab kaw.
Muaj ntau qhov laj thawj vim li cas lub teeb LED yuav tsis qhib vim muaj teeb meem cuam tshuam. Qhov no muaj ntau yam ua rau qhov zoo ntawm LED teeb nws tus kheej. Raws li qhov tshwm sim, qhov chaw raug puas tsuaj, yog li nws yog ib qho tseem ceeb uas yuav tau siv lawv nyob rau hauv dav dav.
