Koj puas tau muaj daim iav uas ci thaum xub thawj, tab sis tom qab ib xyoos lossis ob xyoos, nws tsuas zoo li tsis kaj ntxiv?
Qhov ntawd tsis yog koj lub tswv yim. Nws hu uateeb lwj(los yog lumen depreciation).
Lub teeb lwj yog dab tsi?
Txhua lub teeb ci LED tau dimmer me ntsis thaum lub sijhawm. Nws yog ib txwm. Tab sis ceev npaum li cas lawv dim nyob ntawm peb yam:LED nti zoo, tsav tsheb zoo, thiab cua sov dissipation.
Dab tsi ua rau nws hnyav dua?
Tsis zoo LED chips - lawv degrade sai dua.
Tus neeg tsav tsheb tsis zoo tsim - tsis ruaj khov tam sim no ua kom dimming.
Tsis zoo cua sov dissipation - tshav kub yog yeeb ncuab ntawm LED. Qhov kub dua lub nti khiav, qhov ceev nws ploj.
Dab tsi ua rau nws kav ntev?
Zoo zoo chips
ruaj khov tsis tu ncua - tsav tsheb tam sim no
Thaum tshav kub kub dissipation (aluminium thav duab pab ntau heev)
Peb ua dab tsi txawv
Tag nrho peb cov iav LED siv cov chips zoo, cov tsav tsheb ruaj khov (tsim thiab ua hauv -} tsev), thiab aluminium thav duab rau cua sov. Tias yog vim li cas peb qhov ci ci nyob ib puag ncig ntev dua li kev xaiv pheej yig dua.
Ib qho ntxiv
Lub teeb lwj yog qhov qub. Nws tsis txhais hais tias daim iav tawg. Tab sis yog tias qhov ci ntsa iab poob qis hauv ib xyoos - qhov zoo tsuas yog tsis nyob ntawd.
