Qee lub sij hawm LED tawg tam sim ntawd, dab tsi tuaj yeem yog vim li cas? Nov yog yim qhov laj thawj thiab kev daws teeb meem los qhia rau koj.
1. Cov teeb meem tshwm sim los ntawm kev siv hluav taws xob tsis zoo:
Xyuas seb lub hwj huam mov puas ua hauj lwm ib txwm, seb lub teeb qhia kev qhia puas yog, yog tias tsis yog, thov xyuas seb lub hwj huam mov txuas nrog;
Xyuas seb lub hwj chim qaum ntawm lub teeb hlaws 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 rau lawv kom raug.
2.LED teeb hlaws rau qhov yuav tsum tau muaj voltage:
Lub 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. Tshaj dhau tam sim no yuav scorch lub wick.
Siv 2.4V rechargeable roj teeb, daj yog ib qho yooj yim rau hlawv, vim hais tias txawm tias qhov voltage tsis siab, tab sis tam sim no loj heev, nws tseem yuav kub hnyiab tau.
Thaum siv cov roj teeb pob, txawm hais tias qhov hluav taws xob ntawm lub pob khawm roj teeb yog 3V, qhov tso tawm tam sim no ntawm lub pob roj teeb me me, yog li 3V LED teeb hlaws yuav tsis raug hlawv. Yog li ntawd, thaum siv LED teeb hlaws dai, koj yuav tsum xaiv cov khoom siv fais fab 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 ib qho kev tiv thaiv ib txwm raug ntsia!
3. Yuav ua li cas faib cov luminous xim ntawm LED teeb hlaws dai
Yog tias nws tsis muaj lub hwj chim, yog tias koj xav ua kom yooj yim rau kev xaiv thaum yuav khoom, nws raug nquahu kom npaj 3V khawm roj teeb, uas tuaj yeem siv tau yooj yim xyuas seb lub LED tawm li cas thaum xaiv.
4. Yog vim li cas rau qhov kub ntawm high-power LED teeb hlaws dai:
Lub sab sauv thiab sab ob filaments yog hu ua kub xov hlau nyob rau hauv peb kev lag luam. Cov kub ntshiab yog siv los ua hluav taws xob. Ob tug ncej zoo thiab ob tug ncej tsis zoo. Ib qho khoom zoo tiag tiag yuav muaj ib txoj hlua thib tsib, uas yog welded rau Zener raj. Tiv thaiv.
Qhov luv luv ntawm cov filament twb qhia rau koj kom meej tias koj lub teeb tau raug kub hnyiab los ntawm ib tug loj tam sim no, uas yog sib npaug rau ib tug Circuit Court breaker.
Lub zog hluav taws xob 1W tsav tam sim no yog kwv yees li 350ma, thiab qhov 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.
Feem ntau, aluminium substrates ntawm peb 1W teeb yog tsav los ntawm 12V. Ob peb ntawm lawv siv 220V ncaj qha. Xyuas seb puas muaj qhov tam sim no tsis tu ncua lossis 12V tsav fais fab mov.
5. Yog vim li cas rau yellowing ntawm LED teeb hlaws dai
Lub yellowing ntawm LED sab nrauv encapsulant feem ntau yog tshwm sim los ntawm kev 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 cov khoom siv sab nraud ntev dhau lawm.
Kev daws: Yuav ua tiav cov txheej txheem sab nraud thiab tus neeg saib xyuas, xws li cov qauv 800 lossis 2339 kua nplaum ntawm kev lag luam tshuaj zoo. Cov xwm txheej hauv qab no yuav tsis tshwm sim. Tsis tas li ntawd, ua tib zoo saib xyuas kev tswj hwm ntau lawm thiab ua raws li cov lus qhia ua haujlwm kom tsis txhob muaj cov laj thawj xws li ntau dhau lossis tsis txaus lub sijhawm ci. Qhov xwm txheej no tswj tau zoo.
6. Yog vim li cas rau qhov to ntawm LED teeb hlaws dai
Lub tshuab tsis yog hauv av, thiab cov neeg ua haujlwm tsis hnav lub ntsej muag electrostatic (yuav tsum tau corded). Kev tiv thaiv tsis zoo static los ntawm. Hauv cov txheej txheem ntim khoom, PAD ntawm cov hlua khi yog offset, thiab thaum kawg qhov zoo ntawm cov nti nws tus kheej tau muab zais.
7. LED teeb hlaws yuav tsum yog qhov teeb meem ntawm lub peev xwm thiab inductive load
Qhov tseeb, tsis yog ob qho tib si, LED teeb hlaws yog lub diode, nws xav tau qhov hluav taws xob zoo ua haujlwm, feem ntau 2-3.5V, ntxiv rau, theem tam sim no tuaj yeem tswj qhov ci ntawm LED teeb hlaws. Hauv lwm lo lus, LED teeb hlaws cia li 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:
Tsis zoo thermal conductivity ntawm hlau bracket.
Yellowing ntawm epoxy resin.
Kev sib cuag ntawm cov nti thiab kev txhawb nqa tsis nyob ze txaus.
Lub nti attenuation yog loj.
