Vim li cas LED nti tau hlawv?
High-power LED teeb hlaws tuaj yeem txuas ntxiv ua haujlwm nyob rau hauv ntau qhov sib txawv. Txawm li cas los xij, ib zaug LED teeb hlaws yog corroded, LED teeb hlaws yog tshuaj lom neeg los ntawm ib puag ncig ib puag ncig, uas yuav txo qis kev ua haujlwm ntawm LED teeb hlaws.
Cov yam ntxwv ua rau lub zog loj coj teeb hlaws kom hlawv tawm:
1) Lub sab sauv thiab sab filaments yog hu ua cov xov hlau kub hauv kev lag luam. Kub ntshiab yog siv rau hluav taws xob conduction. Muaj ob qhov zoo electrodes thiab ob qhov tsis zoo electrodes. Cov khoom tiag tiag yuav muaj ib txoj hlua thib tsib, uas yog welded rau Zener raj. tiv thaiv nyhuv
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) Lub zog hluav taws xob 1W tsav tam sim no nyob ib puag ncig 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 cov txhuas substrates ntawm peb 1W teeb yog tsav los ntawm ib ncig ntawm 12V, thiab ob peb ntawm lawv tau siv ncaj qha ntawm 220V. Koj puas xav tias tsis muaj qhov tam sim no tsis tu ncua lossis 12V tsav fais fab mov?
Yuav ua li cas nrog kev kub siab ntawm high-power LED teeb hlaws:
1. Ua kom lub ntim ntawm lub tshuab radiator;
2. Siv thermal paste los txhim kho cov cua sov kom zoo;
3. Lub hwj chim yog super loj, thiab muaj cov dej ntws kom txias;
4. Saib daim ntawv tshaj tawm, muaj kiv cua kom txias txias.
