Nyob rau hauv cov ntaub ntawv ntawm COB LEDs , nws muaj peev xwm mus txuas ncaj qha a COB LED rau a lub dab dej kub (saib daim duab 2). Raws li qhov tshwm sim, COB LEDs ua tsis yog xav tau PCBs txhawm rau teeb tsa LEDs mus rau hauv lub luminaire thiab cov txheej txheem rov ua dua tom ntej tsis tsim nyog ntxiv lawm.

Ntawm no, vim li cas LEDs xav tau lub rhaub dej kub?

Cov cua sov yog ib feem tseem ceeb ntawm LED teeb pom kev zoo vim tias lawv muab txoj hauv kev kom sov mus los ntawm LED lub teeb ci rau sab nraud.

Tom qab ntawd, lo lus nug yog, qhov kub npaum li cas LED cov dab dej kub tau txais? Txawm li cas los xij, thaum koj txav ze rau lub teeb, lub sijhawm nce mus txog 143 degrees. Qhov kub tshaj plaws ntawm tshav kub nyob sab nraub qaum ntawm Putco Silver-Lux LED qhov kub nce mus txog 143 degrees. Qhov kub thiab txias tseem ceeb tshaj qhov muag halogen, thiab feem ntau LED taub hau qhov muag teev.

Tsis tas li, puas LED sawb teeb xav tau lub dab dej kub?

Ua tsis tsuas yog tso siab rau ib qho txhuas tshav kub kom ploj mus tshav kub deb ntawm cov LEDs. Cov khoom lag luam yuav tsum tau tsim ntawm qib kev tiv thaiv kom ntseeg tau tias lub neej ntev dua. 2. Xim zoo thiab raug - Thaum koj yuav ib lub 'sov dawb' ua LED sawb teeb koj yuav tsum tsis txhob cia siab tias yuav tau txais xim dawb ci los ntawm LEDs.

Cov tsav tsheb LED puas kub?

Thaum tshav kub kub yog yeeb ncuab ntawm electronics thiab qhov no mus rau LED tsav tsheb ib yam nkaus. Qhov no tsis txhais hais tias LED tsav tsheb tsis tuaj yeem ua haujlwm hauv kub ib puag ncig, lawv tuaj yeem ua tau. Tab sis muaj qee qhov kev ceev faj yooj yim uas koj tuaj yeem ua kom tsis txhob poob vim kub dhau. Nws qhia tau hais tias ua haujlwm kub ntawm -40 txog +70 degrees Celsius.
