Lub zog siab LED nti cov teeb meem zoo thiab cov kev daws teeb meem
① Nws yog qhov teeb meem tshwm sim los ntawm lub zog tsis zoo:
1. Xyuas seb lub hwj huam mov puas ua hauj lwm zoo li qub, thiab seb lub teeb taw qhia puas qhib. Yog tias nws tsis nyob rau, thov xyuas seb lub hwj chim txuas puas zoo;
2. Xyuas seb lub hwj chim qaum ntawm lub teeb hlaws puas zoo txuas nrog qhov zoo thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob, thiab seb nws puas rov qab los. Yog tias muaj teeb meem saum toj no, thov txuas lawv kom raug.
② LED teeb hlaws rau qhov yuav tsum tau muaj voltage:
Nominal 3V LED teeb hlaws, qhov tseeb, cov xim sib txawv muaj cov kev xav tau sib txawv rau tam sim no, daj yuav tsum muaj qhov tsawg tshaj plaws tam sim no, ua raws li liab, ntsuab, dawb, thiab xiav. Ntau dhau tam sim no yuav hlawv lub wick.
Siv lub roj teeb 2.4V rechargeable, daj yog ib qho yooj yim rau hlawv, vim hais tias txawm tias qhov hluav taws xob tsis loj, tab sis tam sim no loj heev, nws tseem yuav kub hnyiab tau.
Thaum siv lub pob roj teeb, vim tias lub pob roj teeb voltage yog 3V, tab sis vim tias lub pob roj teeb tawm tam sim no tsawg heev, 3V LED teeb hlaws yuav tsis raug hlawv. Yog li ntawd, thaum siv LED teeb hlaws dai, koj yuav tsum xaiv lub hwj huam uas tsim nyog, ua tib zoo saib xyuas qhov voltage thiab tam sim no.
Thaum xaiv cov khoom siv hluav taws xob, yog tias nws tsis ua tau raws li qhov yuav tsum tau muaj ntawm LED teeb hlaws, lub voj voog yuav tsum tau txhim kho, thiab qhov kev tiv thaiv ntau ntxiv!
③ Yuav ua li cas faib cov xim luminous ntawm LED teeb hlaws:
Nyob rau hauv cov ntaub ntawv uas tsis muaj fais fab mov, nws raug nquahu kom npaj 3V khawm roj teeb kom yooj yim ntawm kev xaiv thaum lub sijhawm yuav khoom, thiab siv lub roj teeb no kom yooj yim xyuas seb lub teeb ci LED tawm thaum xaiv.
④ Yog vim li cas rau kev kub hnyiab ntawm high-power LED teeb hlaws:
1. Lub sab sauv thiab sab filaments yog hu ua kub xov hlau nyob rau hauv peb kev lag luam. Cov kub ntshiab yog siv los ua hluav taws xob. Muaj ob qhov zoo electrodes thiab ob qhov tsis zoo electrodes. Ib yam khoom zoo tiag tiag yuav muaj ib lub xov tooj thib tsib, uas yog welded rau Zener raj. tiv thaiv
2. Thaum cov filament ua luv luv, nws yuav qhia meej rau koj tias koj lub teeb tau raug kub hnyiab los ntawm cov tam sim no loj, uas yog sib npaug rau qhov qhib Circuit Court.
3. Kev tsav tsheb tam sim no ntawm high-power 1W yog hais txog 350ma, thiab kev ua haujlwm voltage yog nyob nruab nrab ntawm 3.2-3.6V. Thov xyuam xim thaum siv nws. Tshaj tam sim no yuav twv yuav raug hlawv lub teeb.
4. Feem ntau, aluminium substrates ntawm peb lub teeb 1W yog tsav los ntawm 12V, thiab qee qhov ntawm lawv tau siv ncaj qha ntawm 220V. Koj puas xav pom tias qhov tam sim no tsis tu ncua lossis 12V tsav lub zog hluav taws xob ploj lawm?
⑤ Yog vim li cas rau yellowing ntawm LED teeb hlaws:
Yog vim li cas rau qhov yellowing ntawm LED sab nrauv sealant feem ntau yog vim qhov tsis sib haum xeeb ntawm epoxy resin thiab tus neeg sawv cev kho, tab sis nws tsis tuaj yeem txiav txim siab tias lub sijhawm ci ntawm lub sealant sab nraud ntev dhau lawm.
Kev daws: yuav ua tiav txheej txheej sealing txheej thiab kho tus neeg sawv cev, xws li Shanghai Fine Chemical' s qauv 800 lossis 2339 kua nplaum, cov xwm txheej hauv qab no yuav tsis tshwm sim, thiab xyuam xim rau kev tswj ntau lawm, ua raws li kev ua haujlwm nruj me ntsis. cov lus qhia, thiab zam dhau lub sijhawm ci ntau dhau lossis tsis txaus. , qhov xwm txheej no tswj tau zoo.
⑥ Yog vim li cas rau qhov to ntawm LED teeb hlaws:
Cov cuab yeej siv tshuab tsis yog hauv av, thiab cov neeg ua haujlwm tsis hnav electrostatic wristbands (yuav tsum tau corded). Kev tiv thaiv tsis zoo electrostatic. Tom qab ntawd muaj cov txheej txheem ntim khoom, cov vuam hlau PAD yog kev tsis ncaj ncees, thiab thaum kawg qhov teeb meem tsis zoo ntawm lub nti nws tus kheej.
⑦ LED teeb hlaws yuav tsum yog ib qho teeb meem ntawm lub peev xwm thiab inductive loads:
Qhov tseeb, lawv tsis yog. LED teeb hlaws yog lub diode. Nws xav tau ib qho hluav taws xob txuas ntxiv mus ua haujlwm, feem ntau 2-3.5V. Tsis tas li ntawd, qhov loj me tam sim no tuaj yeem tswj qhov ci ntawm LED teeb hlaws. Uas yog hais, LED teeb hlaws tsuas yog hloov hluav taws xob hluav taws xob mus rau lub teeb lub zog.
⑧ Yog vim li cas rau kev lwj loj ntawm LED teeb hlaws:
1. Lub nplhaib hlau tsis zoo thermal conductivity.
2, Epoxy resin yellowing.
3. Kev sib cuag ntawm cov nti thiab lub bracket tsis kaw txaus.
4. Chip attenuation yog loj.
