LED teeb pom kev zoo yog dab tsi?
LED teeb pom kev zoo yog hais txog qhov tseeb tias lub teeb ci ntawm LED yuav qis dua qhov kev siv lub teeb qub tom qab ua haujlwm ib lub sijhawm, thiab qhov qis dua yog lub teeb lwj ntawm LED. Feem ntau, LED ntim cov tuam txhab yuav ua qhov kev sim los ntawm teeb lub LED kom tas li 1000 teev nrog 20MA ncaj qha tam sim no los sib piv lub teeb siv ua ntej thiab tom qab nws tau teeb nyob rau hauv qhov chaw kuaj mob (Ntawm chav ntsuas kub ntawm 25 ° C).
Txog lub teeb lwj, cov qauv sab hauv yog:
Lub luminous lwj yog 0 ntawm 1000 teev yog, 1% ntawm 3000 teev, 3% ntawm 10,000 teev, thiab luminous lwj ntawm 50,000 teev tsis ntau tshaj 30%.
Lub ambient kub ntawm LED teeb hlaws mus txog lub tswv yim lub neej yog 30 degrees. Ua li no, qhov kub ntawm lub bracket thaum lub teeb dawb LED teeb ua haujlwm yuav tsis tshaj 45 degrees. Tau kawg, qhov siab dua qhov kub, qhov nrawm dua lub teeb tawg ntawm lub teeb hlaws.
