Yuav ua li cas kom paub qhov txawv coj hlaws thiab SMD?
Lub kaum ntse ntse: Lub kaum sab xis ntawm cov hlaws LED me heev, uas yog qhov tseem ceeb ntawm lub teeb, qhov khwv tau ntev heev, tab sis txoj kev khoob khaus yog txwv; thiab lub dav ntawm SMD loj heev, uas belongs rau lub teeb tawg, qhov kev txawv txav yog dav, tab sis qhov ntau yog ze.
Luminescence Principle: LED hlaws dai tawm, thaum SMD txias.
Seismic tsis kam: Lub seismic tsis kam ntawm cov hlaws LED tsis zoo li cov teeb meem ntawm LED.
Cov teeb pom kev zoo: LED hlaws daig tuaj yeem tawm liab, txiv kab ntxwv, daj thiab ntsuab lub teeb, thaum lub sijhawm hauv plab LED tsis muaj peev xwm no.
Kev tiv thaiv ib puag ncig: Cov hlaws hluav taws xob tsis muaj mercury, uas yog muaj teeb meem hlau. Nyob rau hauv kev sib piv, qhov tiv thaiv ib puag ncig ntawm cov thaj ua rau thaj chaw tsis zoo txaus.
